Scientists design molecule that reverses some fragile X syndrome defects

Posted: Published on September 5th, 2012

ScienceDaily (Sep. 4, 2012) Scientists on the Florida campus of The Scripps Research Institute have designed a compound that shows promise as a potential therapy for one of the diseases closely linked to fragile X syndrome, a genetic condition that causes mental retardation, infertility, and memory impairment, and is the only known single-gene cause of autism. The study, published online ahead of print in the journal ACS Chemical Biology September 4, 2012, focuses on tremor ataxia syndrome, which usually affects men over the age of 50 and results in Parkinson's like-symptoms -- trembling, balance problems, muscle rigidity, as well as some neurological difficulties, including short-term memory loss and severe mood swings. With fragile X syndrome, tremor ataxia syndrome, and related diseases, the root of the problem is a structural motif known as an "expanded triplet repeat" -- in which a series of three nucleotides are repeated more times than normal in the genetic code of affected individuals. This defect, located in the fragile X mental retardation 1 (FMR1) gene, causes serious problems with the processing of RNA. "While there is an abundance of potential RNA drug targets in disease, no one has any idea how to identify or design small … Continue reading

Women's breasts age faster after multiple pregnancies – but nursing and hormone replacement therapy are the secrets to …

Posted: Published on September 5th, 2012

PUBLISHED: 17:42 EST, 4 September 2012 | UPDATED: 06:41 EST, 5 September 2012 A study of identical twins has shown that breast feeding, daily moisturising and hormone replacement therapy positively affects how a woman's breasts age. However smoking, drinking alcohol and having multiple pregnancies can accelerate breast aging, according to researchers. The study, published today, shows how environmental factors, as well as higher body mass index (BMI) and larger bra and cup sizes can make breasts appear less beautiful over time. Twin Sisters in Tank Tops Side by Side --- Image by Annie Engel/Corbis Using 161 twins aged between 25 and 74 for the study, plastic surgeon Hooman T. Soltanian of University Hospitals Case Medical Center in Cleveland, Ohio identified specific lifestyle behaviors that can slow the aging process in order to avoid plastic surgery. According to the American Society for Aesthetic Plastic Surgery, nearly 316,848 women had breast augmentations and 127,054 had breast lifts last year. Dr Soltanian told ABC News: 'It's very rare that both twins have been through the same exact environmental factors throughout life. 'The idea was that they have the same [breasts] from a genetic standpoint. If we see a difference, it's more likely to … Continue reading

Tumor suppressor genes vital to regulating blood precursor cells in fruit flies

Posted: Published on September 5th, 2012

Public release date: 5-Sep-2012 [ | E-mail | Share ] Contact: Kim Irwin kirwin@mednet.ucla.edu 310-425-9457 University of California - Los Angeles Health Sciences UCLA stem cell scientists have shown that two common tumor suppressor genes, TSC and PTEN, are vital to regulating the stem cell-like precursor cells that create the blood supply in Drosophila, the common fruit fly. The researchers examined a signaling pathway called TOR that the cells use to gauge nutrition levels and stress, said study senior author Dr. Julian A. Martinez-Agosto, an assistant professor of human genetics and pediatrics and a researcher with the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. "We wondered how an organism knows how many blood cells to make and when to make them in the context of injury and repair to tissue. In particular, we wondered how the blood progenitor cells sense that change and know when it's time to make more blood cells," Martinez-Agosto said. "We found that the TOR pathway uses these two genes to regulate its function and, when activated, it expands or increases the number of blood progenitor cells in the fly's blood." The study appears Sept. 5, 2012 in the … Continue reading

Hope for paralysed patients as stem cell jab restores feeling to patients with damaged spines

Posted: Published on September 5th, 2012

By Daily Mail Reporter PUBLISHED: 12:03 EST, 4 September 2012 | UPDATED: 02:38 EST, 5 September 2012 Patients with broken spines have reported having feeling restored to areas that had previously been paralysed, after receiving stem cell injections. Scientists said they were 'encouraged' after two of three patients injected with donated foetal brain tissue responded to treatment at Balgrist University Hospital in Zurich, Switzerland. Each patient had around 20million neural stem cells delivered directly into their injured spinal cords between four and eight months after they were injured. Early tests suggest stem cells could restore feeling to people with damaged spinal cords Before the treatment none of the patients could feel anything below the nipples. Just three months after therapy two of the patients reported feeling some sensation. By six months they could detect both touch and heat between the chest and belly button. The third patient detected no changes. Stephen Huhn, vice president of StemCells in Newark, California, that is developing the treatment told the New Scientist: 'The face we've seen responses to light touch, heat and electrical impulses so far down in two of the patients is very unexpected. 'They're really close to normal in those areas now … Continue reading

FDA, UCSF Partnership Helps Industry Identify Drug Interactions

Posted: Published on September 5th, 2012

UCSF's Kathleen Giacomini, PhD, a leader in the study of pharmacogenomics how an individuals genetics determine his or her response to medicines, is partnering with the Food and Drug Administration on a project to identify drug interactions before the medicines reach patients. Drug interactions and drug side effects occur all-too-often in patients lives. Now theres a new online resource to help guide pharmaceutical developers as they endeavor to improve testing for potentially harmful drug interactions before new medicines reach consumers. The UCSF-FDA TransPortal is the result of partnership spearheaded by UCSF and the U.S Food and Drug Administration (FDA). Its focus is on how drugs interact with gatekeeper proteins called membrane transporters. Transporters play specific roles as hosts or bouncers to either boot out specific drugs or to escort them inside. They control whether drugs can gain access to cells and organs throughout the body, including the liver and kidneys big players in drug metabolism and elimination. In recent years specific transporters have been found to play a role in drug side effects, such as the muscle pain and weakness sometimes caused by statins. Transporters influence the effectiveness of certain anti-cancer treatments. An unanticipated drug interaction with a transporter associated … Continue reading
