Discovery of new tumor suppressor for lung cancer

Cancer and cell biology experts at the University of Cincinnati (UC) have identified a new tumor suppressor that may help scientists develop more targeted drug therapies to combat lung cancer.

Researchers show mechanisms that regulate DNA damage control and replication

Scientists at Burnham Institute for Medical Research (Burnham) have demonstrated important new roles for the protein kinase complex Cdc7/Dbf4 or Cdc7/Drf1 (Ddk) in monitoring damage control during DNA replication and reinitiating replication following DNA repair.

Discovery of 'on switch' for cell death signaling mechanism

Scientists at Burnham Institute for Medical Research (Burnham) have determined the structure of the interactions between proteins that form the heart of the death inducing signaling complex (DISC), which is responsible for triggering apoptosis (programmed cell death).

Discovery of new syndrome associated with severe congenital neutropenia

A team of scientists has discovered a new syndrome associated with severe congenital neutropenia (SCN), a rare disorder in which children lack sufficient infection-fighting white cells, and identified the genetic cause of the syndrome: mutations in the gene Glucose-6-phosphatase, catalytic subunit 3 (G6PC3).

Discovery of new genetic markers for ulcerative colitis

An international team led by University of Pittsburgh School of Medicine researchers has identified genetic markers associated with risk for ulcerative colitis.

Dormant cancer cells rely on cellular autophagy to survive

A single tumor-suppressing gene is a key to understanding, and perhaps killing, dormant ovarian cancer cells that persist after initial treatment only to reawaken years later, researchers at The University of Texas M. D. Anderson Cancer Center report in the December Journal of Clinical Investigation.

Culprit found in rare type of baldness

Scientists in Beijing say they have discovered a genetic cause for a certain type of premature baldness and they suggest their discovery offers hope in future that those who inherit this rare type of baldness will eventually be able to keep their hair.

Discovery of potential important pathway for controlling cell loss and survival in Parkinson's disease

Neurologists have observed for decades that Lewy bodies, clumps of aggregated proteins inside cells, appear in the brains of patients with Parkinson's disease and other neurodegenerative diseases.

Study links MiR-29 molecule to muscle maturation, muscle cancer

Researchers at The Ohio State University Comprehensive Cancer Center have discovered that a molecule implicated in leukemia and lung cancer is also important in muscle repair and in a muscle cancer that strikes mainly children.

Scientists genetically grab PTEN by the tail to curtail cancer

When researchers look inside human cancer cells for the whereabouts of an important tumor-suppressor, they often catch the protein playing hooky, lolling around in cellular broth instead of muscling its way out to the cells' membranes and foiling cancer growth.

Laminin-111 shows potential for congenital muscular dystrophy

Current research suggests laminin, a protein that helps cells stick together, may lead to enhanced muscle repair in muscular dystrophy.

Lung cancer cells activate inflammation to induce metastasis

A research team from the University of California, San Diego School of Medicine has identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells.

In lung cancer, silencing one crucial gene disrupts normal functioning of genome

While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism.

Scientists isolate genes that made 1918 flu lethal

By mixing and matching a contemporary flu virus with the "Spanish flu" - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.
