Chemical sensitivity of TRPA1 ion channel may boost melanin production

Last year, a team of researchers at Brown University discovered that certain skin cells use a light-sensitive receptor found outside of the eye to sense ultraviolet light and quickly begin pumping out melanin to protect against DNA damage.

BRCA1-deficient cancer cells take advantage of DNA repair mechanism

Cancer cells are resourceful survivors with plenty of tricks for staying alive. Researchers have uncovered one of these stratagems, showing how cells lacking the tumor suppressor BRCA1 can resume one form of DNA repair, sparing themselves from stagnation or death. The study appears in the January 21st issue of The Journal of Cell Biology.

Itch-specific nerve cells: an interview with Associate Professor Xinzhong Dong

Itch was actually defined by a German physician more than 350 years ago. His name was Samuel Hafenreffer. He defined itch as an unpleasant sensation that makes people want to scratch. You probably think this is a very simple definition but itch is really a very complex sensory modality.

Calcium receptor – potential drug target for sleeping sickness

While its common name may make it sound almost whimsical, sleeping sickness, or African trypanosomiasis, is in reality a potentially fatal parasitic infection that has ravaged populations in sub-Saharan Africa for decades, and it continues to infect thousands of people every year.

Researchers identify signaling pathway used by malarial parasites to destroy host cells

One of the most insidious ways that parasitic diseases such as malaria and toxoplasmosis wreak their havoc is by hijacking their host's natural cellular processes, turning self against self.

Study finds evidence of how daily changes in temperature affect the fruit fly's internal clock

New research led by a team at Queen Mary, University of London, has found evidence of how daily changes in temperature affect the fruit fly's internal clock.

Medications often prescribed for PAH could affect heart health of treated patients

A research team with the Faculty of Medicine & Dentistry at the University of Alberta reported findings that significantly improve understanding of how widely used drugs in Pulmonary Arterial Hypertension (PAH) affect the heart health of treated patients.

Miscarriage and molecular signals: an interview with Prof Brosens and Prof Quenby

Miscarriage is defined as the spontaneous loss of pregnancy before the baby reaches viability. Besides the physical trauma, miscarriage causes considerable anxiety, stress, and depression.

Boehringer Ingelheim receives FDA Priority Review for afatinib to treat EGFR mutation-positive NSCLC

Boehringer Ingelheim today announced that the New Drug Application (NDA) for its investigational oncology compound afatinib has been accepted for filing and granted Priority Review by the U.S. Food and Drug Administration (FDA).

Astellas announces FDA acceptance of Tarceva sNDA for EGFR activating mutation-positive NSCLC

Astellas Pharma US, Inc., a U.S. subsidiary of Tokyo-based Astellas Pharma Inc., today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing a supplemental New Drug Application (sNDA) for Tarceva (erlotinib) for first-line use in people with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) activating mutations.

Study: Patients with EGFR exon 20 insertions need targeted therapies

Exon 20 insertions are the third most common family of epidermal growth factor receptor (EGFR) mutations found in non-small-cell lung cancer (NSCLC). Little is known about cancers harboring these mutations aside from their lack of response to EGFR tyrosine kinase inhibitors, impairing the development of effective targeted therapies. A recent study published in the February 2013 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology, concludes that patients with EGFR exon 20 insertions have similar clinical characteristics to those with common EGFR mutations, but a poorer prognosis.

Tamoxifen can counteract some pathologic features in mouse model of DMD

A new study has found that tamoxifen, a well-known breast cancer drug, can counteract some pathologic features in a mouse model of Duchenne muscular dystrophy (DMD). At present, no treatment is known to produce long-term improvement of the symptoms in boys with DMD, a debilitating muscular disorder that is characterized by progressive muscle wasting, respiratory and cardiac impairments, paralysis, and premature death.

Blocking cholesterol biosynthesis pathway in cancer cells appears to improve ability of common drugs

Shutting down a specific pathway in cancer cells appears to improve the ability of common drugs to wipe those cells out, according to new research from scientists at Fox Chase Cancer Center, published in the January issue of Cancer Discovery.
