HDAC inhibitors may be used to fight against skin cancers

In a study published in the journal Developmental Cell, Sarah Millar PhD, professor of Dermatology and Cell & Developmental Biology at the University of Pennsylvania School of Medicine, and colleagues demonstrate that a pair of enzymes called HDACs are critical to the proper formation of mammalian skin.

Exposure to BPA during perinatal development impairs reproductive capacity of female offspring

Exposure to a ubiquitous environmental chemical during pregnancy may impair reproductive capacity of female offspring, according to a study published online in advance of print on December 2 in Environmental Health Perspectives. Fertility decreased over time in female mice that had been exposed during fetal and neonatal (perinatal) development to doses of bisphenol-A (BPA) that were lower than or equal to human environmental exposure levels.

Odors in womb sensitize fetus to smells, alters brain development

A major new study shows that a pregnant mother's diet not only sensitizes the fetus to those smells and flavors, but physically changes the brain directly impacting what the infant eats and drinks in the future.

Disrupting estrogen pathway can halt expansion of breast cancer stem cells: Research

Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis, are stimulated by estrogen via a pathway that mirrors normal stem cell development.

FDA-approved anti-parasite drug blocks Wnt signaling pathway in colon cancer

An old pinworm medicine is a new lead in the search for compounds that block a signaling pathway implicated in colon cancer. The findings, reported by Vanderbilt University Medical Center researchers in the November issue of Nature Chemical Biology, suggest a fresh approach for developing therapeutics that target the pathway.

Cold Spring releases new series of laboratory manuals

Sophisticated techniques that permit the visualization of dynamic processes in cells, tissues, and organ systems at extraordinary levels of resolution have become tremendously valuable in biological research. However, finding the right imaging method and optimizing it for data collection can be a daunting process, even for an established imaging laboratory. To fill this need, a new series of laboratory manuals has been developed by Cold Spring Harbor Laboratory Press. The first volume in this series, Imaging: A Laboratory Manual, has just been released.

Toxic darts may yiled new strategies to control disease-causing pathogens

In nature, it's a dog-eat-dog world, even in the realm of bacteria. Competing bacteria use "toxic darts" to disable each other, according to a new study by UC Santa Barbara biologists.

Researchers find link between genetic defect and sticky mucus in cystic fibrosis

An imbalance of salt and water in patients with cystic fibrosis makes their lungs clog up with sticky mucus that is prone to infection. The cause of the offending imbalance is a well-known genetic error, one that blocks the molecular expressway for tiny chloride ions to move across the surface of the lungs.

Study suggests microRNA binding site helps improved prognosis of colorectal cancer at early stage

A variant site linked to poor outcome in advanced colorectal cancer has now been found to predict improved prognosis in early stages of cancer, according to research presented at the American Association for Cancer Research special conference on Colorectal Cancer: Biology to Therapy, held Oct. 27-30, 2010.

Researchers use fruit fly for cancer research

SMALL and with a life cycle of just two weeks, fruit flies are seen by many as pests and a problem all year round. However, for nearly a century, the humble insect, officially known as Drosophila melanogaster, which measures no more than 3mm, has performed a vital role in genetics and developmental biology.Fruit flies are genetically diverse and easy to use in research, helping scientists in a variety of studies, from how the brain functions to how cancer develops.

Mirna announces USPTO allows claims to therapeutic application of let-7 miRNA

Mirna Therapeutics, Inc. announced today that the USPTO has allowed claims related to the therapeutic application of let-7 in the regulation of oncogenes. The claims derive from a patent application that was submitted by Yale University and exclusively licensed to Mirna related to the pioneering work of Dr. Frank Slack, Professor of Molecular, Cellular & Developmental Biology at Yale University in New Haven, CT.

Novel bioelectric signals can cause stem cells to trigger melanoma-like growth in pigment cells

Biologists at Tufts University School of Arts and Sciences have discovered that a change in membrane voltage in newly identified "instructor cells" can cause stem cells' descendants to trigger melanoma-like growth in pigment cells. The Tufts team also found that this metastatic transformation is due to changes in serotonin transport. The discovery could aid in the prevention and treatment of diseases like cancer and vitiligo as well as birth defects.

Scientists discover mechanism of anticancer drug to kill cancer cells

A potent drug derived from an evergreen tree may soon save the lives of some patients with the deadliest form of breast cancer. According to the National Cancer Institute, breast cancer will claim approximately 40,000 lives in the U.S. this year.

New York Stem Cell Foundation names first six NYSCF Investigators

In an expansion of its ongoing effort to promote the next generation of stem cell scientists, The New York Stem Cell Foundation (NYSCF) today named the first six NYSCF Investigators. Each of the NYSCF-Robertson and NYSCF-Helmsley Investigators will receive up to $1.5 million over the next five years to expand their own laboratories, train other scientists and foster innovative high-risk/high reward research to explore the therapeutic potential of stem cells derived from humans and model organisms.

Matchmaker function may help cardiologists understand the natural repair process after heart attacks

Heart muscle cells do not normally replicate in adult tissue, but multiply with abandoned during development. This is why the loss of heart muscle after a heart attack is so dire-you can't grow enough new heart muscle to make up for the loss.

PDGF identified as key factor in proliferation and transformation of epicardial cells

In research that one day may lead to the discovery of how to regenerate tissue damaged by heart disease, investigators at Childrens Hospital Los Angeles have identified PDGF as a key factor in the proliferation and transformation of epicardial cells, one type of cell that surrounds heart muscle and contributes to vessels.

NIH awards $2.4 million to help disabled students for careers in neuroscience

The National Institutes of Health (NIH) awarded nearly $2.4 million Friday to University of Colorado Anschutz Medical Campus researcher Diego Restrepo and Elba Serrano of New Mexico State University Las Cruces to help them prepare minority students and those with disabilities for careers in neuroscience.

Researchers report MALAT1 gene regulates pre-mRNA splicing in cancer

Researchers report this month that MALAT1, a long non-coding RNA that is implicated in certain cancers, regulates pre-mRNA splicing a critical step in the earliest stage of protein production. Their study appears in the journal Molecular Cell.
