Researchers discover key enzymes that are critical for sperm function

Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms.

Study identifies SIRT2 tumor suppressor protein linked to cancer

The list of aging-associated proteins known to be involved in cancer is growing longer, according to research by investigators at Vanderbilt-Ingram Cancer Center and the National Institutes of Health.

Researchers identify age-dependent beta cell proliferation pathway

As a person ages, the ability of their beta cells to divide and make new beta cells declines. By the time children reach the age of 10 to 12 years, the ability of their insulin-producing cells to replicate greatly diminishes. If these cells, called beta cells, are destroyed-as they are in type 1 diabetes-treatment with the hormone insulin becomes essential to regulate blood glucose levels and get energy from food.

WTSI announces new technique to reprogramme human cells

Researchers from the Wellcome Trust Sanger Institute today announce a new technique to reprogramme human cells, such as skin cells, into stem cells. Their process increases the efficiency of cell reprogramming by one hundred-fold and generates cells of a higher quality at a faster rate.

Aduro initiates CRS-207 and GVAX Pancreas Cancer Vaccine Phase 2 clinical trial

Aduro BioTech, Inc. announces the treatment of the first patient in the Phase 2 pancreatic cancer clinical trial of the sequential administration of two cancer vaccines: Aduro's CRS-207 and GVAX Pancreas Cancer Vaccine.

Researchers identify unusual genomic architecture linked with very severe forms of disease

When cells divide normally, DNA gets copied perfectly and distributed among the daughter cells with an even hand. Occasionally though, DNA breaks during division and is rearranged, resulting in duplications or deletions of important parts of the blueprint.

Scientists discover that DNA modifications in brain cells change due to stimulated brain activity

Johns Hopkins scientists investigating chemical modifications across the genomes of adult mice have discovered that DNA modifications in non-dividing brain cells, thought to be inherently stable, instead underwent large-scale dynamic changes as a result of stimulated brain activity.

G-Zero receives NIAID's Phase II Small Business Innovation Research Grant

G-Zero Therapeutics, an RTP company started in 2008 based on technologies from the University of North Carolina at Chapel Hill, has been awarded a $3 million Phase II Small Business Innovation Research Grant from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.

Study provides insight into earliest stages of some cancers

A novel technique that enables scientists to measure and document tumor-inducing changes in DNA is providing new insight into the earliest events involved in the formation of leukemias, lymphomas and sarcomas, and could potentially lead to the discovery of ways to stop those events.

UCSF scientists identify how normal cells transform into brain tumors

Brain tumor specimens taken from neurosurgery cases at the University of California, San Francisco (UCSF) Medical Center has given scientists a new window on the transformation that occurs as healthy brain cells begin to form tumors.

Scientists discover effective target to kill late-stage metastatic prostate cancer cells

Purdue University scientists believe they have found an effective target for killing late-stage, metastatic prostate cancer cells.

Afinitor Phase III study on angiomyolipomas associated with TSC meets primary endpoint

A Phase III study of Afinitor (everolimus) tablets in patients with non-cancerous kidney tumors, or angiomyolipomas, associated with tuberous sclerosis complex (TSC) met its primary endpoint of best overall angiomyolipoma response rate, which includes reduction in kidney tumor size and absence of new tumors.

Combination of Afinitor, exemestane reduces risk of breast cancer progression in women

A pivotal Phase III study shows Afinitor (everolimus) tablets plus exemestane, a hormonal therapy, more than doubled the time women lived without tumor growth (progression-free survival; PFS) and significantly reduced the risk of cancer progression by 57% versus exemestane alone in patients with advanced breast cancer.

Breast cancer drug combination could stop cancer “in its tracks”

The results of a new study revealed that treatment for women with HER2-positive breast cancer – an aggressive form of the disease which is diagnosed in 10,000 British women each year – slowed the progression of tumors by 40 per cent compared with conventional drugs. Tests on 137 women showed that the new therapy – called T-DM1 – which combines the drug Herceptin with an antibody drug, instead of with standard chemotherapy, appeared to stop the cancer “in its tracks”.

Drug combo for breast cancer in post-menopausal women shows promise

Combining two drugs in post-menopausal women with a certain type of advanced breast cancer more than doubled the time they lived without their disease getting worse, a new study data showed.

Researchers analyse effects of BPA in an in-vitro culture of ovaries

Researchers at Universitat Aut-noma de Barcelona, in collaboration with the Vall d'Hebron Hospital Fetal Tissue Bank, the Department of Gynaecology and the Research Unit of Paediatric Endocrinology, analysed the effects of Bisphenol A (BPA), a polymer widely used to manufacture plastics, in an in vitro culture of ovaries.

Study reveals possible new treatment targets for diffuse intrinsic pontine gliomas

Study led by St. Jude Children's Research Hospital scientists points to possible new treatment targets for diffuse intrinsic pontine gliomas; may tip the scales in the current debate about tumor biopsies.

FoxM1 protein plays a critical role in development of medulloblastomas

Medulloblastomas constitute the most frequent class of malignant childhood brain tumor. Tumors of this type arise due to the uncontrolled proliferation of immature nerve cells in the developing brain, and there is no targeted treatment available.

UNC-45A protein plays critical role in breast cancer cell division and migration

Researchers have found that a protein linked to cell division and migration and tied to increased cell proliferation in ovarian tumors is also present at high levels in breast cancer specimens and cell lines. The protein, dubbed "UNC-45A," was also determined to be more active in breast cancer cells than in normal breast cells.

Researchers identify promising new therapies for ependymoma

Researchers have identified promising new therapies for ependymoma, a rare tumor with few treatment options. St. Jude Children's Research Hospital investigators led the effort, which used a new, faster drug development system that combines the latest drug screening technology with the first accurate animal model of the tumor.
