Mechanism discovered that can send cells on the road to cancer

Using a common virus as a tool for investigating abnormal cell proliferation, a team led by scientists at Cold Spring Harbor Laboratory (CSHL) has succeeded in clarifying an intricate series of biochemical steps that shed light on a way that cancer can begin.

Discovery of gene that may influence metastasis risk in breast cancer

Researchers have identified a pattern of gene activity in mice that may help to predict individual risk for breast cancer metastasis and survival in humans. A single gene, called bromodomain 4 (Brd4), regulates the expression of this pattern, also called a signature.

New insight into the pathogenesis of neurodegeneration in Ataxia telangiectasia

An upcoming paper from Dr. David Wassarman (University of Wisconsin School of Medicine and Public Health) in the May 1 issue of G&D lends new insight into the pathogenesis of neurodegeneration in Ataxia telangiectasia.

Stem cell marker controls two key cancer pathways

Researchers at Georgetown University Medical Center have discovered that a gene associated with human breast stem cells can stimulate development of mammary cells by activating two critical cancer pathways.

Blood pressure drugs halt pancreatic cancer cell growth

Researchers at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia are inching closer to understanding how common blood pressure medications might help prevent the spread of pancreatic cancer.

New regulatory circuit identified for aggressive, malignant brain tumor

Research using a newly developed algorithm has significantly advanced understanding of the molecular events associated with the most common primary brain tumor in adults, human glioblastoma (GBM).

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.

20 Feb 2008

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.
