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. The research, published in the journal Gastroenteroloy1, also reveals how a technique called RNA interference can – by inactivating both genes - kill, in just 48 hours, as much as 80% of cancer cells. These are extremely promising results if transferred into new therapies for humans against a disease, which is still one of the most common cancers in the western world.

In 1928 Alexander Fleming discovered penicillin, which was subsequently developed into a medicine by Florey and Chain in the 1940s. The antibiotic was hailed as a 'miracle cure' and a golden age of drug discovery followed. However, frequent rediscovery of known natural products and technical challenges forced pharmaceutical companies to retreat and stop looking for new molecules.
Big pharmacy companies gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology. Scientists have been mining microbial genomes for new natural…
Researchers at Columbia University Medical Center have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders.
Maria Karayiorgou, M.D., professor of psychiatry, and Joseph A. Gogos, M.D., Ph.D., associate professor of physiology and neuroscience at Columbia University Medical Center explain how they uncovered a previously unknown alteration in the production of microRNAs of a mouse modeled to have the same…
