Apoptosis is programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

Mitochondria play role in pathogenesis of AD and estrogen-induced neuroprotection

As the major source of free radicals in cells, mitochondria contribute to the high levels of oxidative stress believed to play a role in the pathogenesis of Alzheimer's disease.

FDA approves TREANDA (bendamustine hydrochloride) for chronic lymphocytic leukemia

Cephalon, Inc. has announced that the U.S. Food and Drug Administration (FDA) has approved TREANDA (bendamustine hydrochloride) for Injection for the treatment of patients with chronic lymphocytic leukemia (CLL), a slowly progressing blood and bone marrow disease, on March 20, 2008.

Discovery of role of rare gene mutations in schizophrenia

Using an important new method that can be applied in the study of other psychiatric illnesses, scientists at Cold Spring Harbor Laboratory (CSHL) in collaboration with colleagues at the University of Washington (UW) and the National Institute of Mental Health (NIMH), have identified multiple, individually rare gene mutations in people with schizophrenia that may help explain how that devastating illness is caused.

Red wine antioxidant resveratrol kills cancer

Rochester researchers showed for the first time that a natural antioxidant found in grape skins and red wine can help destroy pancreatic cancer cells by reaching to the cell's core energy source, or mitochondria, and crippling its function.

First detailed look at the molecular pathways underlying sleep apnea

Researchers at the University of Pennsylvania School of Medicine have provided, for the first time, a detailed look at the molecular pathways underlying sleep apnea, which affects more than twelve million Americans, according to the National Institutes of Health.

The effect of melatonin on colitis

In rats with experimental colitis, the marked increase in bacterial translocation in postcolitis rats has been reversed by melatonin administration.

Potential new neuronal tumor suppressor

In a G&D paper published online ahead of its April 1 print publication date, Dr. William Kaelin (Dana Farber Cancer Institute) and colleagues identify a potential new neuronal tumor suppressor.

How diabetes drives atherosclerosis

Researchers have discovered how diabetes, by driving inflammation and slowing blood flow, dramatically accelerates atherosclerosis, according to research to be published in the March 14 edition of the journal Circulation Research. Experts once believed that atherosclerosis, or hardening of the arteries, developed when too much cholesterol clogged arteries with fatty deposits called plaques.

Switch for programmed cell death promotes spread of glioblastoma

Malignant tumors have usually lost their ability to destroy themselves by programmed cell death, or apoptosis.

How do infections and toxins launch a cell's self-destruct and alarm system?

Cells are coded with several programs for self-destruction.

Molecular alliance that sustains embryonic stem cell state

One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of a molecular alliance between a specific group of key proteins known as transcription factors, a research team led by the Genome Institute of Singapore (GIS) under the Agency for Science, Technology and Research (A*STAR) reports in the current issue of Nature Cell Biology.

Protein in embryonic stem cells control malignant tumor cells

A protein that governs development of human embryonic stem cells (hESCs) also inhibits the growth and spread of malignant melanoma, the deadliest skin cancer, Northwestern University researchers have discovered.

Isotretinoin and acne

The most potent drug available for the treatment of acne is 13-cis retinoic acid (13-cis RA; also known as isotretinoin); however, little is known about the mechanism by which it acts.

New discovery on programmed cell death

Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process.

New genetic link to schizophrenia

Schizophrenia emerges from an altered pattern of brain development, and researchers continue to search for the genes that cause the brain to develop along a path that ultimately leads to schizophrenia.

Potential novel class of drugs for treating heart attacks and stroke

A new compound that blocks an early step in cell death could lead to a novel class of drugs for treating heart attacks and stroke.

High zinc status in lung cells slows growth and induces DNA

Researchers at the University of Maryland at College Park have discovered that Normal Human Bronchial Epithelial (NHBE) cells cultured in medium with elevated zinc level, at the high end of plasma zinc attainable by oral supplementation, demonstrated inhibition of cell growth, up-regulation of growth arrest and DNA damage-induced gene (Gadd45) mRNA and protein expression, and blockage of G2/M cell cycle progression.

Newly discovered ERK pathway proteins related to CagA induced disease

Cytotoxin-associated gene A protein (CagA) from type I H.pylori has been proved by epidemiological and experimental studies to be closely associated with the H.pylori induced gastric diseases, especially gastric cancer.

Potential new strategy for treating lupus

Immune cells that would normally die in healthy people accumulate in bodies of patients who have lupus and contribute to the disease, according to new Saint Louis University research published in the Feb. 15 issue of Immunity.

Maslinic acid from olives shows anti-cancer properties

A research group of the University of Granada has found out that maslinic acid, a compound present in the leaf and the olive skin wax extracted from alpeorujo (crushed olive pulp), has the capacity of preventing cancer as well as regulating apoptosis in carcinogenic processes.
