Researchers identify several gene mutations responsible for medulloblastoma

Researchers at the Stanford University School of Medicine and Lucile Packard Children's Hospital have identified several gene mutations responsible for the most common childhood brain tumor, called medulloblastoma, adding evidence to the theory that the diagnosis is a group of genetically distinct cancers with different prognoses. These and accompanying findings are likely to lead to less-toxic, better-targeted treatment approaches over the next two years, the researchers said.

Molecular interaction between structural HCV protein and protein critical to viral replication identified

Scientists from the Florida campus of The Scripps Research Institute have identified a molecular interaction between a structural hepatitis C virus protein (HCV) and a protein critical to viral replication. This new finding strongly suggests a novel method of inhibiting the production of the virus and a potential new therapeutic target for hepatitis C drug development.

Scientists uncover minute mechanism of nuclear pore complexes at molecular level

Dr. Joseph Glavy at Stevens Institute of Technology studies the smallest and most basic elements of life. The Assistant Professor of Chemical Biology runs the Glavy Lab, where advanced student scientists study the nuclear pore complexes (NPCs) in cells, observing the minutest mechanisms of life as they unfold during mitosis. The Glavy Lab's formal purpose is to study the NPC at the molecular level in the pursuit of the unknown or unexpected in the well-studied but not always well-understood nuclei of living cells.

Recql5 identified as a tumor suppressor in GI tract

Recql5 is a member of the mammalian RecQ helicase family. Genetic mutations that result in loss of RecQ helicase activity give rise to disorders that are associated with cancer predisposition and premature aging, such as Bloom, Werner, and Rothmund-Thomson syndromes. This class of enzymes is best known for their role in maintaining the integrity of the genome to prevent oncogenic mutations.

New discovery on DNA repair mechanism

Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. Their findings could lead to ways of enhancing chemotherapy drugs that destroy cancer cells by damaging their DNA.

DNA template could explain evolutionary shifts

Rearrangements of all sizes in genomes, genes and exons can result from a glitch in DNA copying that occurs when the process stalls at a critical point and then shifts to a different genetic template, duplicating and even triplicating genes or just shuffling or deleting part of the code within them, said researchers from Baylor College of Medicine in a recent report in the journal Nature Genetics.
