Raf Kinase Inhibitor Protein plays a role in controlling the active movement of cells

University of Illinois at Chicago researchers report that a protein that regulates key signaling pathways in cells also plays a role in controlling the active movement or migration of cells. The finding may suggest new pharmaceutical therapies for treating a variety of diseases, including cancer.

Change in gene may be underlying molecular defect in some colorectal cancers

Inactivation of a DNA repair gene may be an early step in the development of sporadic colorectal tumors, and detection of the molecular basis for this inactivation may ultimately be useful in risk assessment for colorectal cancer, according to a new study in the current issue of the Journal of the National Cancer Institute.

Antibiotic resistance has put humans in an escalating 'arms race' with infectious bacteria

...as scientists try to develop new antibiotics faster than the bacteria can evolve new resistance strategies. But now, researchers have a new strategy that may give them a leg up in the race -- reproducing in the lab the natural evolution of the bacterial enzymes that confer resistance.

Increased ovarian cancer risk not linked to cancer family history

Women with a strong family history of breast cancer but who don't have breast cancer genetic mutations can now be reassured that they are not at increased risk for ovarian cancer, according to a new study by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC).

Study reveals critical molecular events in the origin of fat cells

A new study reveals critical molecular events in the origin of fat cells. The findings are central to understanding chronic diseases, such as obesity and diabetes, as fat cells produce hormones critical for metabolic control, the researchers said.

New research adds to the emerging range of functions that miRNAs perform in an organism

In an effort to understand the biological function of the microRNA mir1, Drs. Nicholas Sokol and Victor Ambros (Darmouth Medical School) have studied the expression profile, transcriptional regulation and loss-of-function phenotype of Drosophila mir-1 (Dmir-1).

Suppression of FOXO1a gene might kill resistant alveolar rhabdomyosarcoma (ARMS) tumors

FOXO1a caused death of tumor cells in laboratory study by triggering expression of caspase-3, which blocks cell division and causes cells to undergo apoptosis, according to St. Jude.

Researchers identify gene prevalent in the population that controls the clinical severity of asthma

The study by Bucala and his colleagues in Dublin, Ireland, included experiments in mice that are resistant to developing asthma because they lack the gene, and an examination of a human population in Dublin chosen for their similar ethnic and geographic identity.

Link between CAPON gene and schizophrenia

We have known for a long time that there is a genetic component to schizophrenia, but nailing down the gene(s) has not been easy.

Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence

Using a recently developed mouse model of breast cancer, a team from the University of Pennsylvania School of Medicine has shown that Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence.

Approximately 25 percent of how a person ages is inherited from parents

According to professor Thomas Kirkwood of the University of Newcastle, there is no single gene for ageing. Throughout time, Humans have used energy to get food, produce offspring and survive danger - not to repair and maintain cells. So the maintenance system in the body slowly breaks down.

Study points to importance of MYC gene in cancer progression

The cancer gene MYC is among the most commonly overexpressed oncogenes in human cancers. Most human cancers demonstrate high levels of MYC or its biological partners, including those of the breast, ovaries, lung, prostate, and skin, as well as leukemias and lymphomas.
