Santaris Pharma releases positive data on LNA-based survivin inhibitor

Santaris Pharma announced today that SPC3042, a RNA-based antisense oligonucleotide developed using the company's proprietary Locked Nucleic Acid (LNA) technology, potently blocks survivin, a key survival protein in cancer cells, in both in vitro and in vivo models of prostate cancer. Importantly, SPC3042 works synergistically with the anticancer drug paclitaxel (Taxol) in both model systems.

How RNA polymerase kick starts gene activation revealed

How 'molecular machines' inside cells swing into action to activate genes at different times in a cell's life is revealed in new research published in Molecular Cell.

Alternative splicing in genes more prevalent than previously believed

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA.

Simple gene-based blood test, quicker, more accurate evaluation for cystic fibrosis

Researchers at National Jewish Health have identified a simple gene-based blood test that more accurately and quickly measures cystic fibrosis patients' response to therapy than current tests.

Sun-damaged skin does not improve with estrogen treatments

Treating the skin with estrogen can stimulate collagen production-which improves the appearance of the skin-in areas not typically exposed to the sun, according to new research from the University of Michigan Health System.

Rifamycin antibiotics attack tuberculosis bacteria with walls, not signals

Amid concerns about the rising number of new tuberculosis cases worldwide, researchers led by Rockefeller University's Seth A. Darst have reexamined and disproved a theory that describes how a potent class of antibiotics kills a deadly form of bacteria. The findings, which will appear in this week's online issue of the Proceedings of the National Academy of Sciences, not only bring scientists closer to understanding how these antibiotics work but also how the bacteria become resistant to their effects.

How short RNAs influence many proteins

During the last decade, microRNAs have emerged somewhat surprisingly as key players in the way genes are regulated. These short snippets of RNA do their work by interacting with messenger RNAs, which act as blueprints for protein creation.

New biomarker for early cancer detection? Research reveals that 'microRNA' may fit the bill

Scientists at Fred Hutchinson Cancer Research Center have discovered that microRNAs - molecular workhorses that regulate gene expression - are released by cancer cells and circulate in the blood, which gives them the potential to become a new class of biomarkers to detect cancer at its earliest stages. Muneesh Tewari, M.D., Ph.D., and colleagues describe their findings in the July 28 issue of the Proceedings of the National Academy of Sciences.

A glimpse of ancient RNA

Some bacterial cells can swim, morph into new forms and even become dangerously virulent - all without initial involvement of DNA. Yale University researchers describe Friday in the journal Science how bacteria accomplish this amazing feat - and in doing so provide a glimpse of what the earliest forms of life on Earth may have looked like.

Researchers find better way to distinguish melanoma from some benign moles

University of Rochester Medical Center researchers found a new protein produced excessively in malignant melanoma, a discovery that is particularly relevant as skin cancer rates climb dramatically among young women.

An inflamed response

Paul Martin, Professor of Cell Biology in the University of Bristol Departments of Physiology and Pharmacology, and Biochemistry, talked to Cherry Lewis about the discovery made in his lab that speeds up wound healing and reduces the size of the wound scar. She was interested not only in the discovery itself, but also in the processes and years of research that led up to it.

Researchers discover that learning suffers if brain transcript isn't transported far out to end of neurons

Neuroscientists at Georgetown University Medical Center have solved a mystery that lies at the heart of human learning, and they say the solution may help explain some forms of mental retardation as well as provide clues to overall brain functioning.

Combining medical knowledge to save lives

Cardiovascular disease (CVD) is the biggest killer among chronic diseases, claiming 17 million lives globally every year. Yet doctors can only attribute 50% of cardiovascular diseases to known risk factors.

New understanding of how herpes simplex virus 1 hides during inactive phase

Now that Duke University Medical Center scientists have figured out how the virus that causes cold sores hides out, they may have a way to wake it up and kill it.

Like father like son - history of heart attacks in the family

Scientists know that heredity plays an important role in causing heart attacks. However the exact genetic mechanisms that transmit the risk of heart attacks from generation to generation still elude them.

Nanoparticle delivers antisense agent to tumors

A multifunctional drug delivery system consisting of a lipid-based nanoparticle, a standard anticancer drug, and a short nucleic acid designed to augment the activity of that drug has demonstrated the ability to treat drug-resistant tumor cells.

Smad proteins regulate microRNA processing

Researchers at Tufts University School of Medicine and Tufts Medical Center have found that Smad proteins regulate microRNA (miRNA) processing.

New molecular mechanism for colorectal cancer

Scientists in Portugal just found a new molecular mechanism behind colorectal cancer in which a mutated and a normal, but over-expressed, gene cooperate and are both needed to create the disease.

New biological classification of ovarian cancer

A thesis from The Sahlgrenska Academy in Sweden shows that it might be possible to predict with great probability which women with ovarian cancer will survive the disease before painful treatment with antineoplastic agents. A better prognosis would considerably improve the quality of life of patients since the treatment could be made more effective and thereby result in fewer side effects.
