Enzyme complex could be key to new cancer treatments

Penn State scientists are the first to observe in living cells a key step in the creation of adenine and guanine, two of the four building blocks that comprise DNA.

microRNA shown to reduce lung cancer growth

A small RNA molecule, known as let-7 microRNA (miRNA), substantially reduced cancer growth in multiple mouse models of lung cancer, according to work by researchers at Yale University and Asuragen, Inc., published in the journal Cell Cycle.

New hope for victims of macular degeneration and retinitis pigmentosa

Scientists at Schepens Eye Research Institute have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells, a stem-like cell that can generate new retinal cells.

Nuclear protein SATB1 triggers aggressive breast cancer

SATB1 is a nuclear protein well known for its crucial role in regulating gene expression during the differentiation and activation of T cells, making it a key player in the immune system.

Device allows scientists to control gene activity across generations of cells

Just as cells inherit genes, they also inherit a set of instructions that tell genes when to become active, in which tissues and to what extent.

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.

Smoking's effects on genes may play a role in lung cancer development and survival

Smoking plays a role in lung cancer development, and now scientists have shown that smoking also affects the way genes are expressed, leading to alterations in cell division and regulation of immune response.

Ocular melanoma - potential new treatment options

Ocular melanoma is rarely detected before it has grown large enough to impair vision or to metastasize.

Natural secretion marks difference between mole and melanoma

A protein naturally produced and secreted by the body can make the difference between your average mole and melanoma, which killed more than 8,000 people in the United States last year, reveals a new study in the February 8 issue of the journal Cell, a publication of Cell Press.

Protein that controls hair growth also keeps stem cells slumbering

Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently.

Cancer stem cell marker also drives transcription in normal cells

New research links the recently discovered function of a multi-faceted transcriptional complex to control of gene expression in both normal cells and cancer stem cells.

Genetic evolution of tumours according to their growth dynamics.

A study co-directed by the Universidad Complutense de Madrid and La Paz hospital in Madrid identifies a protein of high expression in cells located at the tumour boundary that could play an essential role in the evolution of tumours and their invasive potential.

Discovery of 480 genes that control human cell division

A team of U.S., Israeli and German scientists used computational biology techniques to discover 480 genes that play a role in human cell division and to identify more than 100 of those genes that have an abnormal pattern of activation in cancer cells.

Discovery of molecular signal that helps muscle regenerate and protects it from atrophy

It does not take much to injure a muscle. Sometimes one sudden, inconsiderate movement does the job.

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer

Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.

Wyeth receives European approval for TORISEL

Wyeth Pharmaceuticals, a division of Wyeth, has announced that the European Commission has approved TORISEL (temsirolimus) for the first-line treatment of patients with advanced renal cell carcinoma (RCC) who have at least three of six prognostic risk factors. TORISEL is the only approved cancer therapy that specifically inhibits the mTOR (mammalian target of rapamycin) kinase, an important regulator of cell proliferation, cell growth and cell survival.

Bortezomib pushes cancer cells into overdrive, so that they self-destruct

University of Michigan Comprehensive Cancer Center researchers have discovered that bortezomib, a promising cancer drug, is able to strike a blow against melanoma tumor cells by revving up the action of a cancer-promoting gene.

Compound of milk thistle shows anti-cancer effects

Recently, scientists demonstrated the anti-cancer effects of silibinin, a major biologically active compound of milk thistle. Being widely used as a folk remedy for liver diseases, milk thistle is safe and well-tolerated, and it protects the liver from drug or alcohol-related injury.

Enzyme sphingosine kinase 2 show to be potential new target to fight cancer

Researchers at the Virginia Commonwealth University Massey Cancer Center have identified the enzyme sphingosine kinase 2 as a possible new therapeutic target to improve the efficacy of chemotherapy for colon and breast cancer.
