Study: Body and head lice are the same species

A new study offers compelling genetic evidence that head and body lice are the same species. The finding is of special interest because body lice can transmit deadly bacterial diseases, while head lice do not.

Mayo Clinic introduces Breast Cancer Genome Guided Therapy Study

The Breast Cancer Genome Guided Therapy Study (BEAUTY Project) will help physicians tailor chemotherapy to breast cancer patients based on their individual genomes and the genomes of their tumors.

KLF15 gene governs the body's ability to burn fat during exercise

While exercise is accepted universally as the most beneficial prescription physicians can write for patients, little is known about the molecular mechanisms that generate its widespread health benefits. Researchers from Case Western Reserve School of Medicine have shed light on this mystery by discovering that a genetic factor, Kruppel-like Factor 15 (KLF15), governs the body's ability to burn fat during exercise.

Aristolochic acid exposure leads to kidney failure and UUC

Aristolochic acid (AA), a component of a plant used in herbal remedies since ancient times, leads to kidney failure and upper urinary tract cancer (UUC) in individuals exposed to the toxin.

Black fly's blood-sucking tactics may be used for medical advancement

Black flies drink blood and spread disease such as river blindness-creating misery with their presence. A University of Georgia study, however, proves that the pesky insects can be useful.

Novel anti-leukemia compound with little toxicity successfully treats zebrafish

A novel anti-leukemia compound with little toxicity successfully treated zebrafish with T-cell acute lymphoblastic leukemia (T-ALL), suggesting its potential to become a new highly targeted therapy for humans - even those resistant to conventional therapies - according to results from a study published online today in Blood, the Journal of the American Society of Hematology (ASH).

Delivering chemotherapy drugs with nanobubbles more deadly to cancer cells

Using light-harvesting nanoparticles to convert laser energy into "plasmonic nanobubbles," researchers at Rice University, the University of Texas MD Anderson Cancer Center and Baylor College of Medicine (BCM) are developing new methods to inject drugs and genetic payloads directly into cancer cells.

Bimodal genes can define molecular subtypes of ovarian cancer

Scientists from Duke University Medical Center have determined that genes acting as molecular "on/off" switches can define clinically relevant molecular subtypes of ovarian cancer, providing ideal potential targets for use in clinical prognostic and diagnostic testing.

Five significant genetic associations for hypothyroidism found

Using its unique online research platform, 23andMe, a leading personal genetics company, has found five significant genetic associations for hypothyroidism in the largest known genome-wide association study of hypothyroidism conducted to date. The details of the study are now available online in the journal PLoS ONE.

Researchers question wisdom of blocking DP1 in patients prone to cardiovascular disease

Niacin, or vitamin B3, is the one approved drug that elevates "good" cholesterol (high density lipoprotein, HDL) while depressing "bad" cholesterol (low density lipoprotein , LDL), and has thereby attracted much attention from patients and physicians. Niacin keeps fat from breaking down, and so obstructs the availability of LDL building blocks.

Heart cells starved of nutrients less likely to be damaged during ischemia, reperfusion

Heart cells starved of nutrients are less likely to be damaged during periods of decreased blood flow and sudden influxes of blood, known as ischemia and reperfusion, and are also less likely to get out of synch with their cellular neighbors, the damaging phenomenon called arrhythmia.

First study to examine links between neurodevelopmental disorders and maternal metabolic conditions

A major study of the relationships between maternal metabolic conditions and the risk that a child will be born with a neurodevelopmental disorder has found strong links between maternal diabetes and obesity and the likelihood of having a child with autism or another developmental disability.

Inflammasome involved in regulating Age-Related Macular Degeneration

Scientists at Trinity College Dublin have discovered that a part of the immune system called the inflammasome is involved in regulating the development of one of the most common forms of blindness, called Age-Related Macular Degeneration.

Researchers identify new gene variants linked with common childhood obesity

Genetics researchers have identified at least two new gene variants that increase the risk of common childhood obesity.

Researchers discover two molecules that control liver glucose production

In their extraordinary quest to decode human metabolism, researchers at the Salk Institute for Biological Studies have discovered a pair of molecules that regulates the liver's production of glucose---- the simple sugar that is the source of energy in human cells and the central player in diabetes.

Scientists discover novel genes that are mutated in stomach cancer

An international team of scientists, led by researchers from the Duke-NUS Graduate Medical School (Duke-NUS) in Singapore and National Cancer Centre of Singapore, has identified hundreds of novel genes that are mutated in stomach cancer, the second-most lethal cancer worldwide.

Two Rev-erb proteins work together to control fat metabolism

The 24-hour internal clock controls many aspects of human behavior and physiology, including sleep, blood pressure, and metabolism. Disruption in circadian rhythms leads to increased incidence of many diseases, including metabolic disease and cancer. Each cell of the body has its own internal timing mechanism, which is controlled by proteins that keep one another in check.
