Normal breast cells provide an innate defense mechanism against cancer

It is well known that the human body has a highly developed immune system to detect and destroy invading pathogens and tumor cells. Now, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the body has a second line of defense against cancer - healthy cells.

Brain damage starts decade earlier in Alzheimer’s patients

A new study published in the journal Neurology has shown that the brains of people diagnosed with Alzheimer's disease start shrinking up to a decade before symptoms appear. Researchers from Rush University Medical Center in Chicago and Massachusetts General Hospital in Boston did brain imaging tests on older adults with no signs of memory loss.

Alternative mechanism through which tumor cells become invasive

Researchers at the Hebrew University of Jerusalem have discovered a previously unknown mechanism whereby tumor cells invade normal tissues, spreading cancer through various organs.

Insight into neurodegenerative diseases

For years, researchers in genome stability have observed that several neurodegenerative diseases-including Huntington's disease-are associated with cell-killing proteins that are created during expansion of a CAG/CTG trinucleotide repeat.

Key enzyme in non-small cell lung cancers could make standard chemotherapy more effective

Scientists at the Barbara Ann Karmanos Cancer Institute in Detroit today presented a study at the American Association for Cancer Research's 102nd Annual Meeting 2011 that identifies a key enzyme in non-small cell lung cancers that could potentially make standard chemotherapy more effective against this highly deadly disease.

Major depression linked to premature aging of immune cells: Study

Certain cases of major depression are associated with premature aging of immune cells, which may make people more susceptible to other serious illness, according to findings from a new UCSF-led study.

OncoGenex presents OGX-427 preclinical data in prostrate cancer at AACR meeting

OncoGenex Pharmaceuticals, Inc. announced today that preclinical data utilizing their pipeline compound OGX-427 was presented at the AACR 102nd Annual Meeting 2011.

Synta presents ganetespib and elesclomol study data in cancer at AACR meeting

Synta Pharmaceuticals Corp. today presented five posters at the American Association for Cancer Research 102nd Annual Meeting. Three posters reported results from studies of ganetespib, and two posters reported results from studies of elesclomol, a small-molecule mitochondria metabolism inhibitor.

Lilly presents results of JAK2, Hedgehog inhibitor preclinical cancer studies at 102nd AACR

Eli Lilly and Company announced results today from two preclinical studies of molecules that target genetic mutations and disable specific signaling pathways that can lead to cancer. The studies evaluated two unique molecules – a JAK2 inhibitor and a Hedgehog inhibitor – with results presented during the American Association for Cancer Research (AACR) 102nd Annual Meeting in Orlando, Fla.

Scientists discover new compounds that may help fight against parasitic diseases

Trypanosomatid parasites cause diseases like African sleeping sickness, Chagas' disease and leishmaniasis. Leishmaniasis affects about 12 million people worldwide, mostly in developing countries. Current drug treatments are inadequate due to drug toxicity and resistance.

Researchers pinpoint effects of enhanced adult neurogenesis in hippocampus

Adult mice engineered to have more newborn neurons in their brain memory hub excelled at accurately discriminating between similar experiences - an ability that declines with normal aging and in some anxiety disorders.

Researchers develop new way to stimulate neuron production in adult brain

Researchers at Columbia University Medical Center have developed a new way to stimulate neuron production in the adult mouse brain, demonstrating that neurons acquired in the brain's hippocampus during adulthood improve certain cognitive functions.

Scientists sequence tumor genomes from 50 breast cancer patients

In one of the largest cancer genomics investigations reported to date, scientists have sequenced the whole genomes of tumors from 50 breast cancer patients and compared them to the matched DNA of the same patients' healthy cells.

Breast cancer genome reveals potential therapeutic targets

Scientists have sequenced the entire genomes of tumors from 50 breast cancer patients and found more than 1,700 gene mutations, most of which were unique to individual patients. The researchers at Washington University in St. Louis and the Siteman Cancer Center suggest that this variability and uniqueness made it difficult to predict outcomes of the cases.

Rsearchers define new step that controls programmed cell death in cancer cells

When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death.

Loss of SKIP sensitizes cancer cells to apoptotic effects of DNA damage-inducing anticancer drugs

When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death. In contrast to other stress-induced genes, which dispense with the regular transcriptional entourage, p21Cip1 still requires SKIP, a transcription elongation factor that also helps with the editing of transcripts, to be expressed, found researchers at the Salk Institute for Biological Studies.

PUMA-mediated intestinal apoptosis contributes to ulcerative colitis in humans, mice

Ulcerative colitis is an inflammatory bowel disease thought to be related to aberrant activation of the immune system in the intestine. Recent research has also suggested that regulated cell death of the intestinal epithelial cells is a contributing factor to the pathogenesis.
