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

Substance found in evening primrose oil inhibits breast cancer gene

Gamma-linolenic acid (GLA), a substance in evening primrose oil and several other plant oils used in herbal medicine, inhibits action of Her-2/neu, a cancer gene that is responsible for almost 30 percent of all breast cancers, Northwestern University researchers report.

Study identifies molecular switch that integrates cell survival signals from multiple intracellular signaling pathways

The finding has substantial clinical significance, as mutations in these cell survival-signaling pathways are associated with many human cancers, and a better understanding of how these pathways converge to regulate the delicate balance between cell proliferation and cell death may lead to development of more effective cancer therapies.

WWOX gene finding could lead to a new strategy for treating lung cancer

The research focused on a gene known as WWOX, which is lost or silenced in a large majority of lung cancers, and in cancers of the breast, ovary, prostate, bladder, esophagus and pancreas. The work was led by scientists at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

E-cadherin, that cellular touch so important in cancer

E-cadherin is a molecule involved in adhesion between epithelial cells that also seems to have a protective role in cancer, since its loss is associated with tumour progression and metastases formation in a series of different cancers.

Fijiian seaweed shows potential to kill cancer cells, bacteria and the HIV virus

Researchers have discovered 10 new molecular structures with pharmaceutical potential in a species of red seaweed that lives in the shallow coral reef along the coastline of Fiji in the south Pacific Ocean.

Researchers find CCL5 protein produced in the course of respiratory viral infections can serve to protect macrophages from an untimely death

Enlisted to help fight viral infections, immune cells called macrophages consume virus-infected cells to stop the spread of the disease in the body.

Mitochondria and apoptosis research

The story of how mitochondria are recruited during times of stress to choreograph apoptosis--the cell's dance of death--is a story that fails to tell which particular set of steps the cells use most often, according to investigators at St. Jude Children's Research Hospital and the La Jolla Institute of Allergy and Immunology (San Diego, CA).

Discovery provides an understanding of the mechanisms of oocyte death and a way to identify potential clinical treatments for infertility

An immature egg's internal nutrient supply is critical to its survival, an insight that offers a new route to understanding and treating infertility due to egg death, according to Duke University Medical Center researchers.

RPL26 and nucleolin play critical roles in controlling the production of p53

Investigators at St. Jude Children's Research Hospital have discovered a previously unrecognized mechanism that controls a key protein linked to the cell's response to stress - a finding that holds promise for new ways to enhance cancer therapies or protect cells from dying after exposure to damaging chemicals or radiation.

9 Oct 2005

Plant-derived compounds appear to block the activity of an enzyme that triggers inflammation in joints

The findings came to light while the researchers were studying the wildly different ways in which cells in human blood vessels and joints respond to pressure gradients generated from liquid moving along their surface, a force called shear stress.

3 Oct 2005

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.

PUMA protein offers critical insights for developing new anti-cancer drugs

The discovery of how the activities of the protein p53 initiate signals that trigger cell suicide offers critical insights for developing new anti-cancer drugs, according to investigators from St. Jude Children's Research Hospital.

20 Sep 2005

New and unusual class of genes plays an important role in the development of chronic lymphocytic leukemia

The study found that the loss of two genes for producing small molecules known as microRNAs enables damaged cells to survive, rather than normally self-destructing before they become cancerous.

Translation elongation factor eEF1A2 is is a potential oncogene that is overexpressed in two-thirds of breast tumors

The tissue-specific elongation factor eEF1A2 might be an oncoprotein involved in breast cancer.

Another use for Botox - enlarged prostate

Botox, appears to alter specific cellular processes that contribute to prostate enlargement according to new study results presented by researchers from the University of Pittsburgh and Chang Gung Memorial Hospital in Taiwan at the International Continence Society annual meeting in Montreal.

Relative of the celebrated COX-2 inhibitor celecoxib is tough tumor fighter

A close structural relative of the celebrated COX-2 inhibitor celecoxib (brand name: Celebrex) is a potent tumor fighter, able to wipe out tumor cells that are resistant to conventional chemotherapies, according to an interdisciplinary team of researchers from the University of Southern California.

Immunity - another important function of the mitochondria

Researchers have discovered a surprise lurking inside mitochondria, the power plants that are present in every cell. It turns out that these powerhouses also contain a protein that triggers the immune system to attack viral invaders.

28 Aug 2005

New technique for creating human embryonic stem cells

Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells. The fusion causes the adult cells to undergo genetic reprogramming, which results in cells that have the developmental characteristics of human embryonic stem cells.

Protein thought to promote lymphoma by merely preventing cancer cells from dying appears to actively promote cancer cell growth

A protein previously thought to merely hinder the activity of a key cellular protein linked to cancer cell death, now appears to mimic the cellular signaling of that protein; potentially leading to the development of lymphoma.

22 Aug 2005

Developmental culling and cancer

A new study reveals that a diverse group of apparently unrelated genes that are associated with pheochromocytoma intersect at a common pathway that drives the necessary culling of cells.
