HLA B-27 protein appears to confer ability to suppress HIV viral replication

The rare ability of some individuals to control HIV infection with their immune system alone appears to depend - at least partially - on specific qualities of the immune system's killer T cells and not on how many of those cells are produced.

Genetic variability in the embryo may predispose to cancer in adult life

A study recently published in Nature Genetics provides new evidence that the genetic makeup of the embryo may cause the appearance of tumors in adult life. These results bear out the growing theory that some tumors may have an extremely early origin, tracing to the individual's embryonic development, while offering new clues to understand the genetic causes of certain kinds of cancer, and their prevention and treatment.

Normal p53 gene makes breast cancer chemotherapy with doxorubicin less effective

Presence of normal p53, a tumor suppressor gene, instead of a mutated version, makes breast cancer chemotherapy with doxorubicin less effective. The preclinical study led by MD Anderson scientists was published today in the journal Cancer Cell.

Researchers identify two proteins that are required to maintain kidney stem cells

Studying mice and humans, researchers at Washington University School of Medicine in St. Louis and their collaborators in Paris have identified two proteins that are required to maintain a supply of stem cells in the developing kidney.

Researchers find pathway for origin and growth of the most common form of brain and spinal cord tumor – meningioma

Johns Hopkins researchers say they have discovered one of the most important cellular mechanisms driving the growth and progression of meningioma, the most common form of brain and spinal cord tumor.

Study reveals mystery of how pancreatic cancer escapes immune detection

Researchers at NYU School of Medicine have made a key discovery that could help doctors treat one of the deadliest cancers.

Study documents altruistic behavior by human embryonic stem cells

When most groups of mammalian cells are faced with a shortage of nutrients or oxygen, the phrase "every man for himself" is more apt than "all for one, one for all." Unlike colonies of bacteria, which often cooperate to thrive as a group, mammalian cells have never been observed to help one another out. But a new study led by a researcher at the Stanford University School of Medicine has shown that certain human embryonic stem cells, in times of stress, produce molecules that not only benefit themselves, but also help nearby cells survive.

RGS proteins play an essential role in night blindness

In a pair of related studies, scientists from the Florida campus of The Scripps Research Institute have identified several proteins that help regulate cells' response to light-and the development of night blindness, a rare disease that abolishes the ability to see in dim light.

Children of older fathers inherit longer telomeres

If your father and grandfather waited until they were older before reproducing, you might experience life-extending benefits. Biologists assume that a slow pace of aging requires that the body invest more resources in repairing cells and tissues.

Polymorphism ’protective in pneumococcal disease’

Patients with invasive pneumococcal disease who have the FcyRIIa-R/R131 polymorphism may have better survival outcomes than those without the genotype, suggest study findings.

Mutation responsible for rare, hereditary motor neuron disease disrupts vital links

Studying how nerve cells send and receive messages, Johns Hopkins scientists have discovered new ways that genetic mutations can disrupt functions in neurons and lead to neurodegenerative disease, including amyotrophic lateral sclerosis (ALS).

$27 million received to speed new treatments for disabling neurological disorder

The Johns Hopkins University School of Medicine has announced receipt of a five-year, $27 million gift earmarked to fast-track the development of therapies to treat tumors associated with neurofibromatosis type 1 (NF1), a common and often debilitating neurogenetic disorder that causes tumors called plexiform neurofibromas to grow on nerves anywhere in the body.

Distinct cancer 'signatures' may help predict response to estrogen-lowering therapy

Decoding the DNA of patients with advanced breast cancer has allowed scientists to identify distinct cancer "signatures" that could help predict which women are most likely to benefit from estrogen-lowering therapy, while sparing others from unnecessary treatment.

Biomedical engineers develop SMART detector for flu diagnosis

In April 2009, the world took notice as reports surfaced of a virus in Mexico that had mutated from pigs and was being passed from human to human. The H1N1 "swine flu," as the virus was named, circulated worldwide, killing more than 18,000 people, according to the World Health Organization. The Centers for Disease Control and Prevention in the United States said it was the first global pandemic in more than four decades.

Promising results for dabrafenib in advanced melanoma

The BRAF inhibitor dabrafenib shows promising results for treatment of advanced melanoma, both alone and in combination with the MEK inhibitor trametinib, show results from two studies presented at the American Society of Clinical Oncology Annual Meeting in Chicago, Illinois, USA.

Discovery answers why mother's immune system does not reject developing fetus as foreign tissue

Researchers at NYU School of Medicine have made an important discovery that partially answers the long-standing question of why a mother's immune system does not reject a developing fetus as foreign tissue.

Decision Resources forecasts the launch of four new agents to treat DMD by 2021

Decision Resources, one of the world's leading research and advisory firms focusing on pharmaceutical and healthcare issues, finds that interviewed experts unanimously identify a disease-modifying therapy as the highest unmet need in the treatment of Duchenne muscular dystrophy (DMD).

Erivedge drug shows promise against advanced basal cell carcinoma

It's the most common form of skin cancer, but in its advanced stages, basal cell carcinoma has the potential to become disfiguring and life threatening. An international phase 2 study headed by Mayo Clinic led to the recent Food and Drug Administration approval of the first drug of its kind to help advanced basal cell carcinoma patients who have few treatment options.

Tp53 genetic mutation may play an important role in prostate cancer

A team of UC Davis investigators has found that a genetic mutation may play an important role in the development of prostate cancer. The mutation of the so-called p53 (or Tp53) gene was previously implicated in late disease progression, but until now has never been shown to act as an initiating factor. The findings may open new avenues for diagnosing and treating the disease.
