Discovery of 13 new tumor-suppressor genes in liver cancer

Over the years, hunting for cancer-related genes and understanding how they work has been an important, although time-consuming, exercise.

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.

Researchers screen 700 molecules by RNAi to identify host factors involved in malaria infection

The researchers of the Malaria Unit at Instituto de Medicina Molecular (IMM, Lisbon, Portugal) publish in the peer reviewed journal PLoS Pathogens the results of a large scale screening of more than 700 genes to identify host factors involved in the liver stage of malaria infection.

Quark Pharmaceuticals' siRNAs examined alone and in xombination with chemotherapy

Quark Pharmaceuticals, Inc. has announced that the journal Cancer Research published results on efficacy of siRNA targeting its proprietary target gene against non-small cell lung cancer (NSCLC) in the edition dated October 1, 2008.

Designer RNA fights high cholesterol, medical researchers find

Small, specially designed bits of ribonucleic acid (RNA) can interfere with cholesterol metabolism, reducing harmful cholesterol by two-thirds in pre-clinical tests, according to a new study by researchers at UT Southwestern Medical Center in collaboration with Alnylam Pharmaceuticals and the Massachusetts Institute of Technology.

RNAi used to dramatically suppress HIV infection in an organism

Hopes languished last September when a promising candidate HIV vaccine failed to work. Despite this setback, many researchers still believe immunization is possible, and a new study suggests they're correct-at least at the cellular level.

Roche acquires Mirus to advance RNAi delivery research

Roche (Basel) and Mirus Bio Corporation (Madison, WI, USA) announced today that they have entered into a definitive agreement under which Roche will acquire Mirus Bio Corporation, a privately-owned US company based in Madison, Wisconsin, that focuses on the discovery and development of innovative nucleic acid based technologies, including a proprietary RNAi (Ribonucleic Acid interference) delivery platform.

Scientists identify 22 genes that control embryonic stem cell fate

Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they suspect. The limbo lies between the embryonic stage and fully differentiated, or specialized, cells, such as bone, muscle or fat.

Researchers detail types of genes necessary for brain

Researchers from Harvard Medical School and Brandeis University have successfully completed a full-genome RNAi screen in neurons, showing what types of genes are necessary for brain development. Details of the screen and its novel methodology are published July 4th in the open-access journal PLoS Genetics.

Protein thought to promote cancer instead functions as a tumor suppressor

A protein previously thought to promote colorectal cancer instead suppresses the growth of human cancer cells in culture, researchers at UT Southwestern Medical Center have found.

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.

A genetic tool for cleaner water

A genetic tool used by medical researchers may also be used in a novel approach to remove harmful microbes and viruses from drinking water.

You may not be what you eat after all!

A new study shows that increased eating does not necessarily lead to increased fat. The finding in the much-studied roundworm opens the possibility of identifying new targets for drugs to control weight, the researchers say.

New treatments for viral and other diseases by blocking genes

The elusive goal of developing effective treatments for viral diseases such as AIDS and influenza has been brought closer by dramatic progress in the ability to interfere with viral genetic machinery. The stage was set for a coordinated European effort to accelerate research and stimulate development of new treatments against viral diseases at a recent research conference organised by the European Science Foundation (ESF).

Scientists reveal the genetic determinants of fat storage in cells

New research by the Gladstone Institutes of Cardiovascular Disease (GICD) and the University of California, San Francisco (UCSF), has revealed the genetic determinants of fat storage in cells, which may lead to a new understanding of and potential treatments for obesity, diabetes, and heart disease. While scientists have long understood that lipid droplets contribute to fat build up in cells, the genes involved in droplet biology have been a focus of extensive research.

Scientists solve mystery about critical mechanism of gene expression

Although letters representing the three billion pairs of molecules that form the "rungs" of the helical DNA "ladder" are routinely called the human "genetic code," the DNA they comprise transmits traits across generations in a variety of ways, not all of which depend on the sequence of letters in the code.
