Combination of exercise and S-nitrosoglutathione improves recovery from stroke

In a study published in the current issue of Restorative Neurology and Neuroscience scientists report that a therapy combining exercise with the neurovascular protective agent S-nitrosoglutathione (GSNO) improved recovery from stroke in a rat model. GSNO is a compound found naturally in the body and it has no known side effects or toxicity.

Targeting elevated HLX gene expression may treat acute myeloid leukemia

Scientists at Albert Einstein College of Medicine of Yeshiva University have made a discovery involving mice and humans that could mean that people with acute myeloid leukemia (AML), a rare and usually fatal cancer, are a step closer to new treatment options. Their study results were published online today in Cancer Cell.

Scientists identify new genetic alterations underlying high-risk subtype of ALL

Scientists have identified new genetic alterations underlying a high-risk subtype of the most common childhood cancer that could be effectively targeted with existing leukemia therapies.

Researchers identify molecular pathway by which Notch regulates cell proliferation in lung cancer

Lung cancer is one of the most aggressive types of cancer and the most common cause of death from this disease worldwide. Despite the progress in the molecular biology of lung cancer achieved in recent years, the mechanisms used by tumor cells to grow and spread throughout the body are not yet completely understood. This lack of information is responsible for the limited range of available therapeutic possibilities and their undesirable side effects.

HHS says billing rule will cut red tape for doctors, save up to $9B

Officials say the interim rule, published Tuesday, will streamline electronic billing for doctors and save time and money.

Interface zone fibroblasts play key role in gastric cancer

Interface zone fibroblasts in gastric adenocarcinoma promote the invasion, migration, and proliferation of cancer cells, as well as prevent apoptosis, to a greater degree than normal or tumor zone fibroblasts, say researchers.

Mammalian cells divide when their growth rate hits a specific threshold

It's a longstanding question in biology: How do cells know when to progress through the cell cycle? In simple organisms such as yeast, cells divide once they reach a specific size. However, determining if this holds true for mammalian cells has been difficult, in part because there has been no good way to measure mammalian cell growth over time.

Potential new drug to treat common inherited kidney disease

Scientists at UC Santa Barbara have demonstrated in the laboratory that a new drug is effective in treating a very common kidney disease -- although it will be a few years before it becomes available for clinical testing. The findings resulted from a collaboration between UCSB and a biotech firm based in Indiana. The study is published in this week's Journal of the American Society of Nephrology.

HSF1 increases expression of chaperones and supports cancer metastasis

Whitehead Institute researchers have found that increased expression of a specific set of genes is strongly associated with metastasis and death in patients with breast, colon, and lung cancers.

Mass. lawmakers unveil bill to cut health costs

Massachusetts lawmakers are expected to vote Tuesday on long-awaited legislation to rein in health care costs. The effort, which would put the state again at the forefront of health policy, will be watched by other states looking to control spiraling costs. After months of debate, House and Senate leaders filed a bipartisan compromise bill of more than 350 pages Monday night that would seek to contain health-care costs by setting a target at which overall state health spending should rise.

Chk1 gene alone is sufficient to kill cancer cells

Researchers at Case Western Reserve University School of Medicine have discovered a mutant form of the gene, Chk1, that when expressed in cancer cells, permanently stopped their proliferation and caused cell death without the addition of any chemotherapeutic drugs.

Biomimetic bioartificial livers and cell toxicity assays: an interview with Dr. Joris Braspenning, CEO Medicyte

Biomimetic bioartificial livers are liver organoids based on synthetic equivalents of the human extracellular matrix (ECM) which will be seeded with human cells.

Gluconeogenesis severely compromised in HCC by IL6-Stat3-mediated activation of miR-23a

As liver cancer develops, tumor cells lose the ability to produce and release glucose into the bloodstream, a key function of healthy liver cells for maintaining needed blood-sugar levels.

Cepheid launches new Xpert BCR-ABL Monitor test

Cepheid today announced the release of an updated Xpert BCR-ABL Monitor test, now incorporating lot-specific standardization using the WHO (World Health Organization) BCR-ABL standards.

Hypoxic lung environment increases HIF-2a tumor growth signaling

In addition to the well-known risk factor of smoking, chronic obstructive pulmonary disease (COPD) increases lung cancer risk.

Stromal cells offer chemotherapy clue in early lung cancer

Podoplanin-positive cancer-associated fibroblasts predict recurrence in stage I lung adenocarcinoma, which could help identify patients suited for adjuvant chemotherapy, research shows.

Study explores role of L. reuteri against foodborne infection

While many bacteria exist as aggressive pathogens, causing diseases ranging from tuberculosis and cholera, to plague, diphtheria and toxic shock syndrome, others play a less malevolent role and some are critical for human health.

Studies report on therapeutic efficacy of stem cell transplantation in animal models of ALS, SCI

Two studies published in a recent issue of Cell Medicine report on the therapeutic efficacy of stem cell transplantation in animal models of amyotrophic lateral sclerosis (ALS) and spinal cord injury (SCI).

Estrogen may mediate low incidence of HCC in women

Study findings suggest that estrogen may have a suppressive effect on hepatocellular carcinoma, potentially explaining its lower incidence in women.

Combination of Dox with MCP shows promise against prostate cancer

Doxorubicin (Dox) is an effective anti-cancer drug, but it's also a very toxic one, causing severe heart and immune damage. The doses needed to impact tumors are not well tolerated by patients, however, researchers may have found an answer through combination therapy.
