  • ‘Open science’ could open doors for pharma

    Posted:Wed, 24 Dec 2014 09:30:00 EST
    When Johnson & Johnson agreed to make its clinical trial data available to outside parties through the Yale School of Medicine, proponents billed it as a victory for transparency in drug research. Those same advocates of so-called “open science” hope it will encourage more pharma companies to do the same.
  • Sunitinib appeared active in meningioma

    Posted:Wed, 24 Dec 2014 08:30:00 EST
    Sunitinib appeared effective in patients with recurrent atypical and malignant meningioma, according to results of a prospective, multicenter, phase 2 trial. Because no effective treatment for patients with surgery- and radiation-refractory meningiomas, the findings suggest a randomized trial should be performed to evaluate sunitinib in this setting, researchers wrote. Sunitinib (Sutent, Pfizer) — a small-molecule tyrosine kinase inhibitor — targets the vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor, both of which are prevalent in meningiomas.
  • NF2 Genetic disorder afflicts large Clinton family

    Posted:Wed, 24 Dec 2014 07:30:00 EST
    Francis Barrette died in 1990 of throat cancer, some 21 years before a devastating diagnosis came to light of an illness that affects 11 members of his extended family ranging in age from 3 to 52 years old. So far, that includes three of his children, as well as some of his grandchildren, great-grandchildren and great-great grandchildren. The disease is called neurofibromatosis type 2, or NF2, a genetic disorder known for uncontrolled growth of non-cancerous tumors in a person’s nervous system.

  • (Abstract) Evidence of polyclonality in neurofibromatosis type 2–associated multilobulated vestibular schwannomas

    Posted:Mon, 15 Dec 2014 07:30:00 EST
    Neurofibromatosis type 2 (NF2) is a tumor syndrome that results from mutation of the NF2 tumor suppressor gene. The hallmark of NF2 is the presence of bilateral vestibular schwannoma (VS). Though NF2-associated and sporadic VS share identical histopathologic findings and cytogenetic alterations, NF2-associated VS often appears multilobulated, is less responsive to radiosurgery, and has worse surgical outcomes. Temporal bone autopsy specimens and MRI of the inner ear performed on NF2 patients suggest that multiple discrete tumors may be present within the labyrinth and cerebellopontine angle.
  • Northwestern Medicine Surgeons Using New Adaptive Hybrid Technology

    Posted:Mon, 15 Dec 2014 06:30:00 EST
    Radiosurgery-guided procedure could offer hope for patients with benign and cancerous brain tumors. It started with numbness on the left side of his face. A few months later, Steve Mores couldn’t feel his tongue or chew on the left side of his mouth. TV commercials featuring food or even being in a grocery store made him nauseous. Northwestern Medicine neurosurgeons are spearheading new adaptive hybrid surgery technology to help patients like Mores. Participating in a phase 1 research study, Mores was one of the first subjects in the United States to have a brain tumor removed using this technology that integrates a radiosurgery plan into surgery.

  • ‘Off switch’ for pain discovered: Activating the adenosine A3 receptor subtype is key to powerful pain relief

    Posted:Mon, 01 Dec 2014 08:00:00 EST
    The scientific efforts led by Salvemini, who is professor of pharmacological and physiological sciences at SLU, demonstrated that turning on a receptor in the brain and spinal cord counteracts chronic nerve pain in male and female rodents. Activating the A3 receptor — either by its native chemical stimulator, the small molecule adenosine, or by powerful synthetic small molecule drugs invented at the NIH — prevents or reverses pain that develops slowly from nerve damage without causing analgesic tolerance or intrinsic reward (unlike opioids).
  • Pac-Man instead of patch: Using video games to improve lazy eye, depth perception

    Posted:Mon, 01 Dec 2014 07:30:00 EST
    Scientists have created video games that add an important element of fun to the repetitive training needed to improve vision in people – including adults – with a lazy eye and poor depth perception. The training tools, including a Pac-Man-style “cat and mouse” game and a “search for oddball” game, have produced results in pilot testing: Weak-eye vision improved to 20/20 and 20/50 in two adult research participants with lazy eyes whose vision was 20/25 and 20/63, respectively, before the training began.
  • Suffolk volunteer with genetic condition gets award

    Posted:Mon, 01 Dec 2014 06:30:00 EST
    A young volunteer who founded a support group for people affected by a rare genetic disorder has been given a high profile award. Jessica Cook, 24, from Stowmarket, was born with NF2 – Neurofibromatosis Type 2 – an incurable condition that affects one in 35,000 people and causes tumours to grow throughout the nervous system, most commonly seen in the brain and spine.
  • Growth factor regenerates damaged nerves without sprouting new blood vessels

    Posted:Mon, 17 Nov 2014 09:30:00 EST
    In experiments with normal mice able to produce VEGF-B, Rosenblatt saw that levels of the growth factor rose significantly around corneal nerves after they were damaged. The findings, he said, warrant further investigation of VEGF-B as a potential therapy to treat corneal nerve damage, which can be caused by dry eye, contact lenses, viruses or eye surgery, in addition to trauma. As a treatment, VEGF-B may prove superior to nerve growth factor, which has been used to treat certain eye diseases but can cause significant eye pain or the growth of new blood vessels.
  • Charity Christmas Single

    Posted:Mon, 17 Nov 2014 09:00:00 EST
    A Christmas single has been released to raise money and awareness for Crowborough based charity Taylor-Made Dreams. The charity was founded by the mother of a Crowborough teenager Taylor Mitchell, who died of a rare nerve disorder in September 2011, aged just 15. Taylor was diagnosed with Neurofibromatosis Type 2, which caused tumours to form in his brain and spine. After the death of her son, Suzi Mitchell founded Taylor Made Dreams to help other terminally-ill youngsters complete their “bucket list”.
  • Sesame Lets Seriously Paralyzed Folks Use Smartphones

    Posted:Mon, 17 Nov 2014 08:30:00 EST
    Our smartphones can both bind us and liberate us in a myriad of ways. They put us in touch with others, help us automate things, and guide us when we’re on our way. All this requires the basic ability to tap a finger on the phone’s screen. Yet, the very people that would most benefit from that capabilities of smartphones are the ones least able to use them. Specifically, paraplegics that can’t move their arms can’t make phone calls, turn lights on and off, and direct a wheelchair through a single interface. To make this possible, project called Sesame is aiming to empower standard smartphones to be used by people who only have movement left above the neck.

  • Toward Gene Editing

    Posted:Mon, 17 Nov 2014 06:30:00 EST
    A team of Harvard researchers has developed a system that uses commercially available molecules called cationic lipids — essentially long, greasy molecules that carry a positive charge at one end — to introduce genome-editing proteins into cells efficiently. David Liu, a professor of chemistry and chemical biology, and colleagues used the new system to modify genes in specialized “hair cells” in the inner ears of mice. Hair cell damage, either from environmental or genetic factors, is a common cause of hearing loss.

  • New progress in treatment of brain cancer and other neurological diseases

    Posted:Fri, 07 Nov 2014 09:30:00 EST
    A new technology that may assist in the treatment of brain cancer and other neurological diseases is the subject of an article in a recent issue of the journal Technology, published by World Scientific Publishing Company. According to the authors, the current medical use of chemotherapy to treat brain cancer can be inefficient because of the blood-brain-barrier that impedes the delivery of drugs out of blood vessels and into the tumor.
  • Blood vessel growth in the brain relies on a protein found in tumor blood vessels

    Posted:Fri, 07 Nov 2014 08:30:00 EST
    Do blood vessels that feed tumors differ from other blood vessels? Fourteen years ago, experiments designed to answer that question led to the discovery of several genes that are more active in tumor-associated blood vessels than in normal blood vessels. New research now reveals the normal function of one of those genes and suggests it could be a good target for anticancer drug therapy.

  • (Abstract) Proteomic screening identifies a YAP-driven signaling network linked to tumor cell proliferation in human schwannomas

    Posted:Mon, 22 Sep 2014 08:30:00 EST
    Research highlight: Inactivation of the NF2 gene predisposes to neurofibromatosis type II and the development of schwannomas. In vitro studies have shown that loss of NF2 leads to the induction of mitogenic signaling mediated by receptor tyrosine kinases (RTKs), MAP kinase, AKT, or Hippo pathways. The goal of our study was to evaluate the expression and activity of these signaling pathways in human schwannomas in order to identify new potential therapeutic targets.
  • (Abstract) The p53/mouse double minute 2 homolog complex deregulation in merlin-deficient tumours

    Posted:Mon, 22 Sep 2014 07:30:00 EST

  • (Abstract) NF2 Invasion of the Internal Auditory Canal Wall: Clinical Significance

    Posted:Wed, 03 Sep 2014 08:30:00 EST
    Research Highlight: The majority of IAC (internal auditory canal) tumors associated with the severe “Wishart” phenotype demonstrate bone invasion within the IAC. Invasion of bone was associated with poorer hearing. The invasive nature of NF2-associated tumors may partially explain their higher recurrence rate after resection. Surgeons managing NF2-related VS should be aware of the small infiltrations of the wall of the IAC when removing these tumors to minimize recurrence.

  • Novel drug action against solid tumors explained

    Posted:Wed, 13 Aug 2014 10:30:00 EST
    Researchers at UC Davis, City of Hope, Taipai Medical University and National Health Research Institutes in Taiwan have discovered how a drug that deprives the cells of a key amino acid specifically kills cancer cells. Their paper, published today in Proceedings of the National Academy of Sciences, is the culmination of nearly a decade of research into the role of arginine – and its deprivation – in the generation of excessive autophagy, a process in which the cell dies by eating itself.
  • (Abstract) LIM domain kinases as potential therapeutic targets for NF2

    Posted:Wed, 13 Aug 2014 09:30:00 EST
    Research highlight: Here we report that mouse Schwann cells (MSCs) in which merlin function is lost as a result of Nf2 exon2 deletion (Nf2(ΔEx2)) exhibited increased levels of LIMK1, LIMK2 and active phospho-Thr508/505-LIMK1/2, as well as phospho-Ser3-cofilin, compared with wild-type normal MSCs. Our results suggest that LIMKs are potential drug targets for NF2 and tumors associated with merlin deficiency.
  • Live subtitles: How smart technology could help deaf people

    Posted:Wed, 13 Aug 2014 08:30:00 EST
    There are many new technologies that can help people with disabilities, like live subtitling 24/7 for deaf people, but how well do they work? So when I first heard about Google Glass – wearable technology that positions a small computer screen above your right eye – I was excited. Live subtitling 24/7 and calling up an in-vision interpreter at the touch of a button. Remarkably both seemed possible.
  • Author sheds light on a little-known degenerative disease

    Posted:Wed, 13 Aug 2014 07:30:00 EST
    Anna Lickley was first diagnosed with the rare inherited disease NF2 as a teenager, undaunted she has lived her life to the full. Julie Marshall reports. The idea for her book, Catch it Anytime You Can, which was published last year, came from a blog that Anna began in 2010 to try and make sense of her condition. Catch it Anytime You Can is available from Amazon and in The Grove Bookshop, Ilkley and Salts Mill Saltaire.
  • Scientists demonstrate long-sought drug candidate can halt tumor growth

    Posted:Wed, 13 Aug 2014 06:30:00 EST
    It’s a trick any cat burglar knows: to open a locked door, slide a credit card past the latch. Scientists at The Scripps Research Institute (TSRI) tried a similar strategy when they attempted to disrupt the function of MYC, a cancer regulator thought to be “undruggable.” MYC is a transcriptional factor, meaning it controls gene expression. When MYC is overexpressed or amplified, the unregulated expression of genes involved in cell proliferation, a key step in cancer growth, follows.
  • SickKids doctors remove teen’s tumour without radiation or surgery

    Posted:Tue, 05 Aug 2014 13:30:00 EST

  • Scientists uncover new clues to repairing injured spinal cord

    Posted:Tue, 05 Aug 2014 07:30:00 EST
    Frogs, dogs, whales, snails can all do it, but humans and primates can’t. Regrow nerves after an injury, that is—while many animals have this ability, humans don’t. But new research from the Salk Institute suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits. Such a feat could eventually lead to therapies for the thousands of Americans with severe spinal cord injuries and paralysis.

  • Understanding How Neuro Cells Turn Cancerous

    Posted:Thu, 31 Jul 2014 10:30:00 EST
    Tumor suppressors exist in cells to prevent abnormal cell division in our bodies. The loss Merlin leads to tumors in many cell types within our nervous systems. There are two copies of a tumor suppressor, one on each chromosome that we inherit from our parents. The loss of Merlin can be caused by random loss of both copies in a single cell, causing sporadic tumors, or by inheriting one abnormal copy and losing the second copy throughout our lifetime as is seen in the inherited condition of neurofibromatosis type 2 (NF2).
  • (Abstract) A neuronal function of the tumor suppressor protein merlin

The aim of this study was to elucidate the underlying molecular differences between these groups. We compared the gene expression pattern between patients with early to late age of onset.
  • Is the next ‘new’ cancer drug already in your medicine cabinet?

    Posted:Thu, 03 Jul 2014 07:00:00 EST
    It turns out that the same types of drugs that help reduce watery eyes and runny noses during allergy season might also help ward off tumors too. A new research report appearing in the July 2014 issue of The Journal of Leukocyte Biology suggests that antihistamines may have significant anti-cancer properties as they interfere with the function of a type of cell that is known to reduce the body’s ability to fight tumors (called “myeloid derived suppressor cells”).

  • Immunotherapies: Strengthening Our Own Defenses to Fight Cancer

    Posted:Thu, 03 Jul 2014 06:00:00 EST
    “Tumor cells are the cells of our body that are somehow changed through genetics or environmental factors which make them proliferate or expand uncontrollably,” says Dr. Gabrilovich, M.D., Ph.D., the Christopher M. Davis Professor of Cancer Research. Over the years, researchers have understood ways in which the immune system can be trained to better fight against cancer. Dr. Gabrilovich described it as a similar process to what is done in order to develop effective vaccines. However, when someone receives a vaccine to protect them from a virus, they develop antibodies, which aren’t that effective in cancer. Instead, immunotherapies are required to help the T-cells work harder at fighting the cancer.

  • Scientists design a molecule that blocks cancer growth in mice

    Posted:Thu, 15 May 2014 09:00:00 EST
    A team of researchers from USC and NYU has developed and patented a small molecule that interferes with cancer progression with minimal side effects. The molecule prevents two critical proteins from interacting by mimicking the surface topography of one protein – like wearing a mask – which tricks the other protein into binding with it. This stops a so-called “transcription factor” that controls the transcription of genetic information. That transcription factor is what would have created an aberrant gene expression, contributing to the cancer growth.
  • Hypertension related to new cancer therapies – a new syndrome emerges

    Posted:Thu, 15 May 2014 08:00:00 EST
    The mechanisms underlying VEGF inhibitor-induced hypertension need to be better understood and there is a need for clear guidelines and improved management, say investigators in a review article published in the Canadian Journal of Cardiology. Angiogenesis inhibitors are a new class of cancer drugs that are designed to prevent the formation of new blood vessels, thereby stopping or slowing the growth or spread of tumours.
  • Possible new plan of attack for opening and closing the blood-brain barrier

    Posted:Thu, 15 May 2014 07:00:00 EST
    The blood-brain barrier helps maintain the delicate environment that allows the human brain to thrive. There’s just one problem: The barrier is so discerning, it won’t let medicines pass through. Researchers haven’t been able to coax it to open up because they don’t know enough about how the barrier forms or functions. Now, a team from Harvard Medical School has identified a gene in mice, Mfsd2a, that may beresponsible for limiting the barrier’s permeability—and the molecule it produces, Mfsd2a, works in a way few researchers expected.

  • Goggles help surgeons ‘see’ tumours

    Posted:Wed, 23 Apr 2014 07:00:00 EST
    Currently doctors treating cancer have two main approaches – bombard the tumour with drugs and radiotherapy or cut it out. The second option is very common but not always successful – because it is often also impossible to tell where the tumour ends and healthy tissue begins. But a new goggle technology being developed in the US lets surgeons “see” which cells are cancerous and which are healthy, increasing the chances that they will be able remove all cancer cells in one operation.

  • (Abstract) Exon-Skipping Antisense Oligonucleotides to Correct Missplicing in Neurogenetic Diseases

    Posted:Tue, 08 Apr 2014 11:00:00 EST
    Around 85% of the germline NF2 mutations are point mutations, among which approximately 25% seem to affect splicing. In the recent work by Castellanos and colleagues, a patient with a deep intronic mutation was identified. This mutation leads to the inclusion of a nonsense pseudoexon of 167nt in the mature mRNA, between exon 13 and exon 14, thus resulting in a truncated Merlin protein. Castellanos and colleagues have been successful in devising a therapeutic strategy for the first time for an NFT 2 case, using a PMO targeting the deep intronic mutation.
  • Paralyzed patients regain movement after spinal implant: study

    Posted:Tue, 08 Apr 2014 10:00:00 EST
    Four men who had each been paralyzed from the chest down for more than two years and been told their situation was hopeless regained the ability to voluntarily move their legs and feet – though not to walk – after an electrical device was implanted in their spines, researchers reported on Tuesday. The success, albeit in a small number of patients, offers hope that a fundamentally new treatment can help many of the 6 million paralyzed Americans, including the 1.3 million with spinal cord injuries. Even those whose cases are deemed so hopeless they are not offered further rehabilitation might benefit, scientists say.

  • Image-guided stereotactic radiotherapy for patients with vestibular schwannoma

    Posted:Mon, 10 Mar 2014 07:00:00 EST
    Research Highlight: Local tumor control and functional outcome after linac-based stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (FSRT) for vestibular schwannoma (VS) were assessed. In all, 250 patients with VS were treated: 190 patients with tumors less than 2 cm diameter underwent SRS and 60 patients with tumors greater than 2 to 3.5 cm underwent FSRT. Using SRS to treat small VS results in good local control rates. FSRT for larger lesions also seems effective. Severe treatment-related complications are not frequent. Therefore, image-guided stereotactic radiotherapy is an appropriate alternative to microsurgery for patients with VS.

The research – hailed when it came out in January as a breakthrough that could herald a new era of medical biology – was covered widely in Japan and across the world after it was published in the highly reputable science journal Nature. But since then, there have been reports that other scientists have been unable to replicate the Japanese team’s results and that there may have been problems with its data and images.
  • In Vivo Functional Analysis of the Human NF2 Tumor Suppressor Gene in Drosophila

    Posted:Sat, 08 Mar 2014 11:00:00 EST
    Research Highlight: Here we describe experiments in which we used Drosophila as an in vivo system to test the functions of the normal human NF2 gene products and patient-derived mutant alleles. Although the predominant NF2 gene isoform, isoform 1, could functionally replace the Drosophila Merlin gene, a second isoform with a distinct C-terminal tail could not. Immunofluorescence studies show that the two isoforms have distinct subcellular localizations when expressed in the polarized imaginal epithelium, and function in genetic rescue assays correlates with apical localization of the NF2 protein.
  • Visual Information Restoration and Rehabilitation via Sensory Substitution Technology

    Posted:Sat, 08 Mar 2014 10:00:00 EST
    Richard Hogle of Wicab, Inc. led a team of interdisciplinary scientists at Wicab, University of Pittsburgh Medical Center, Lighthouse International, and Carnegie Mellon University to further develop the BrainPort V100 device. The V100 is a visual prosthetic that enables perception of visual information using the tongue and a camera system as a paired substitute for the eye. Visual information is collected from a video camera and translated into gentle electrical stimulation patterns on the surface of the tongue. The concept is similar to reading Braille with the fingertips. With training, users can perceive shape, size, location and motion of objects in their environment. This technology is intended to augment, and not replace, other assistive methods such as the white cane or guide dog.

  • Man Sees Wife with NF2 Dying Message

    Posted:Mon, 03 Mar 2014 06:00:00 EST
    After a week of trying, a local man was finally able to view a video his wife left him before she died. Last week, when Charles tried to do just that, he found that Facebook had “memorialized” his wife’s account after determining she had died. That status meant the account would remain locked and all of Shannon’s privacy settings would remain exactly the same, meaning Charles could not locate the video. Then he figured out how to access the video through the iCloud that backed up data from his wife’s old cell phone on which the video was originally recorded.

    Posted:Mon, 24 Feb 2014 06:30:00 EST
    Research Highlight: Tumor recurrence represents a major clinical challenge. Our data show that emergent recurrent tumors acquire a phenotype radically different from that of their originating primary tumors. This phenotype allows them to evade a host-derived innate immune response elicited by the progression from minimal residual disease (MRD) to actively growing recurrence.
  • Could One Cancer Test Find Unrelated Tumors?

    Posted:Mon, 24 Feb 2014 06:00:00 EST
    Researchers looked at 12 major types of cancer and identified 127 repeatedly mutated genes that seem to drive the development and progression of a range of tumors. The discovery sets the stage for devising new diagnostic tools and more personalized cancer treatments. The study, published in Nature, shows that some of the same genes commonly mutated in certain cancers also occur in seemingly unrelated tumors. For example, a gene mutated in 25 percent of leukaemia cases in the study also was found in tumors of the breast, rectum, head and neck, kidney, lung, ovary, and uterus.
  • How a simple injection could help shrink a brain tumour

    Posted:Fri, 14 Feb 2014 15:00:00 EST
    University of Leeds scientists are exploring whether a simple injection could help shrink a brain tumour as part of groundbreaking research. The research team hopes to harness the power of certain viruses that can kill cancerous cells without harming healthy ones. Such viruses target and ‘invade’ tumour cells, multiplying inside the invaded cell until it bursts and is destroyed. They can also be primed with anti-cancer drugs to boost their destructive potential as they home in on tumour cells.

  • FB is 10: Strong support for survivors

    Posted:Fri, 14 Feb 2014 07:00:00 EST
    Finding out that you have an illness or genetic disorder is tough on anyone, what more when you or your loved one has a rare condition that many don’t understand. That is why many patients and/or survivors of several conditions create support groups on social media such as Facebook. Keisha Petrus is a NF2 patient who was diagnosed with the disorder when she was just four years old and has since received several surgeries to remove the tumours.
  • Give the Data to the People

    Posted:Fri, 14 Feb 2014 06:30:00 EST
    Today, more than half of the clinical trials in the United States, including many sponsored by academic and governmental institutions, are not published within two years of their completion. Often they are never published at all. The unreported results, not surprisingly, are often those in which a drug failed to perform better than a placebo. As a result, evidence-based medicine is, at best, based on only some of the evidence. One of the most troubling implications is that full information on a drug’s effects may never be discovered or released.
  • We Are Giving Ourselves Cancer

    Posted:Fri, 14 Feb 2014 06:00:00 EST
    Despite great strides in prevention and treatment, cancer rates remain stubbornly high and may soon surpass heart disease as the leading cause of death in the United States.
