Study identifies how skeletal muscle stem cells respond to muscle injury

A study conducted by Children's Hospital & Research Center Oakland scientists identifies how skeletal muscle stem cells respond to muscle injury and may be stimulated to improve muscle repair in Duchenne Muscular Dystrophy, a severe inherited disease of muscle that causes weakness, disability and, ultimately, heart and respiratory failure.

Viewpoints: Can Medicare taxes really fund student loans?; Daschle on diabetes and kids

In the case of the student loans, the Democrats' bill would require certain Americans -- high-income partners in small businesses that provide professional services, such as engineering or lobbying -- to pay payroll taxes on their share of the firm's profits. That's a long way of saying the bill would eliminate a tax-avoidance strategy that some small firms use to reduce their contributions to Social Security and Medicare.

KLF15 molecule inhibits action of estrogen in the endometrium

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a molecule that inhibits the action of estrogen. This female hormone plays a key role in the growth, maintenance and repair of reproductive tissues and fuels the development of endometrial and breast cancers.

Botanical formula inhibits breast to lung cancer metastasis in mice

Scientists at Indiana University Health's Cancer Research Laboratory have found that a sophisticated botanical formula slows human breast cancer growth and inhibits breast to lung metastasis in mice. The formula contains extracts from medicinal mushrooms, medicinal herbs and purified nutritional compounds, and showed no toxic side-effects.

PDE4 enzyme regulates division of tumour cells and blood vessel growth in cancer tissue

Lung cancer is the leading cause of cancer death throughout the world. Standard treatment methods do not usually result in long-term recovery. In addition to the proliferation of the tumour cells, the growth of blood vessels controls tumors development. The blood vessel growth is controlled by several signalling molecules. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and Justus Liebig University Giessen have discovered a molecule that plays a key role in this process. They succeeded in reducing tumour growth in their experiments by blocking the phosphodiesterase PDE4.

Potential breast cancer patients for new immune-targeting therapies

Breast cancer patients whose tumors express high levels of genes related to immune response are more likely to have their tumor completely eradicated by pre-operative chemotherapy compared to patients with low expression of these genes, Belgian researchers report at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium.

New analysis may help identify breast cancer patients who will benefit from immune suppressant

A new analysis may help doctors identify breast cancer patients who will benefit from treatment with the immune suppressant drug everolimus, say French researchers at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium.

Potential ways for doctors to improve hormone receptor-positive breast cancer treatment

American and Spanish researchers have found potential ways for doctors to improve the treatment of hormone receptor-positive breast cancer even if they lack access to costly multi-gene tests, as they report at the 4th IMPAKT Breast Cancer Conference.

Study: Breast cancer in young women is enriched with aggressive basal-like tumors

Breast cancer in young women is a biologically unique disease that requires customized management strategies, researchers report at the 4th IMPAKT Breast Cancer Conference, in Brussels, Belgium.

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

CAPE arrests growth of prostate cancer cells and tumors in mice

An over-the-counter natural remedy derived from honeybee hives arrests the growth of prostate cancer cells and tumors in mice, according to a new paper from researchers at the University of Chicago Medicine.

Scientists identify first gene associated with congenital asplenia

Researchers at Weill Cornell Medical College and Rockefeller University have identified the first gene to be linked to a rare condition in which babies are born without a spleen, putting those children at risk of dying from infections they cannot defend themselves against. The gene, Nkx2.5, was shown to regulate genesis of the spleen during early development in mice.

Math models can be useful tools for study of cancer progression

Using mathematical models, researchers in the Integrated Mathematical Oncology (IMO) program at Moffitt Cancer Center are focusing their research on the interaction between the tumor and its microenvironment and the "selective forces" in that microenvironment that play a role in the growth and evolution of cancer.

Rexahn obtains additional patent coverage for anti-cancer candidate RX-1792 in Japan

Rexahn Pharmaceuticals, Inc., a clinical stage pharmaceutical company developing and commercializing potential best in class oncology and CNS therapeutics, today announced that the Japanese Patent Office has issued to the Company patent No. 4,934,432, entitled "Quinazoline Derivatives and Therapeutic Use Thereof."

Kras gene triggers metabolic changes that fuel cancer cells

Researchers at Dana-Farber Cancer Institute have shown that advanced pancreatic cancers in mice can't survive without continued expression of a mutant oncogene that "rewires" key metabolic pathways to fuel the cancer cells.

FDA approves Novartis’ Afinitor for treatment of renal angiomyolipomas and TSC

Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Afinitor (everolimus) tablets for the treatment of adult patients with kidney tumors known as renal angiomyolipomas and tuberous sclerosis complex (TSC), who do not require immediate surgery.

Researchers identify new components of genetic pathway that controls neural stem cells

Can one feel too attached? Does one need to let go to mature? Neural stem cells have this problem, too. As immature cells, neural stem cells must stick together in a protected environment called a niche in order to divide so they can make all of the cells that populate the nervous system. But when it's time to mature, or differentiate, the neural stem cells must stop dividing, detach from their neighbors and migrate to where they are needed to form the circuits necessary for humans to think, feel and interact with the world.

Self-degradation response to antidepressant Zoloft observed in yeast cells

Princeton University researchers have observed a self-degradation response to the antidepressant Zoloft in yeast cells that could help provide new answers to lingering questions among scientists about how antidepressants work, as well as support the idea that depression is not solely linked to the neurotransmitter serotonin.

RANK inhibitor-chemotherapy combination may have important therapeutic effects against breast cancer

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have shown that overactivation of the RANK signalling pathway promotes the initiation, progression and metastasis of tumours in human breast epithelial cells by dedifferentiation of breast cells to stem cells. The results of this study have been advanced in the electronic edition of the journal Cancer Research.

Non-coding RNA gives off biological signals during viral infection

Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) - RNA molecules that do not translate into proteins - play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.
