Sequenom CMM authorizes SensiGene T21 LDT clinical validation study

Sequenom, Inc. today announced that the company's wholly-owned reference laboratory, the Sequenom Center for Molecular Medicine (Sequenom CMM), has authorized commencement of a pivotal clinical validation study. This validation study is designed to evaluate the clinical performance of the SensiGene T21 Laboratory Developed Test (LDT) for the detection of an overabundance in maternal blood of chromosome 21, which is associated with fetal chromosome 21 aneuploidy.

Male mice created without Y chromosome

University of Adelaide researchers are a step closer to unraveling the mysteries of human sexual development, following genetic studies that show male mice can be created without a Y chromosome - through the activation of an ancient brain gene.

Genetic variant of brain receptor molecule may contribute to impulsive behavior

A multinational research team led by scientists at the National Institutes of Health has found that a genetic variant of a brain receptor molecule may contribute to violently impulsive behavior when people who carry it are under the influence of alcohol.

Researchers discover protein that suppresses melanoma progression

In a breakthrough that could lead to new treatments for patients with malignant melanoma, researchers from Mount Sinai School of Medicine have discovered that a particular protein suppresses the progression of melanoma through regulation of an oncogene, or gene responsible for cancer growth. The study is published in the December 23 issue of Nature.

mTORC1 cellular pathway affects aging phenotype

Whitehead Institute researchers have linked hyperactivity in the mechanistic target of rapamycin complex 1 (mTORC1) cellular pathway, to reduced ketone production, which is a well-defined physiological trait of aging in mice.

Loyola researcher receives $1.3 million NIH grant to study key heart protein

Loyola University Health System researcher Sakthivel Sadayappan, PhD, has been awarded a four-year, $1.3 million grant from the National Institutes of Health to study a protein that is critical for the normal functioning of the heart.

TMEM106B gene appears to protect against frontotemporal lobar degeneration

Neuroscientists had assumed that a mutation in the progranulin gene, which makes the progranulin protein and supports brain neurons, was sufficient to produce a kind of dementia known as frontotemporal lobar degeneration. But now an international team of scientists led by researchers at Mayo Clinic's campus in Florida have found another genetic factor they say appears to protect against the disorder in progranulin mutation carriers.

Tekmira begins patient dosing in TKM-PLK1 phase 1 trail for cancer

Tekmira Pharmaceuticals Corporation, a leading developer of RNA interference therapeutics, announced today it has initiated patient dosing in a Phase 1 human clinical trial for its lead oncology product, TKM-PLK1. TKM-PLK1 targets polo-like kinase 1, or PLK1, a cell cycle protein involved in tumor cell proliferation and a validated oncology target.

Study finds specially designed probiotic can prevent obesity

Specially designed probiotics can modulate the physiology of host fat cells say scientists writing in Microbiology. The findings could lead to specialised probiotics that have a role in the prevention or treatment of conditions such as obesity.

New nanoparticle-based diagnostic platform provides rapid detection of sepsis

Blood poisoning can be fatal. If you suffer from sepsis, you used to have to wait as much as 48 hours for laboratory findings. A new diagnostic platform as big as a credit card will now supply the analysis after as little as an hour. This system is based on nanoparticles that are automatically guided by magnetic forces.

Gene changes during brain development can lead to male genitalia formation in female embryo

Australian scientists have discovered that changes to a gene involved in brain development can lead to testis formation and male genitalia in an otherwise female embryo.

Excessive carbohydrates, rather than fat, may be the source of America's dietary woes

A growing number of top nutritional scientists are pointing to excessive carbohydrates, rather than fat, as the source of America's dietary woes. As reported in the Los Angeles Times on December 20, some researchers are saying that cutting carbohydrates is the key to reversing obesity, heart disease, Type 2 diabetes and hypertension.

Molecular breakdown of Bicoid protein vital for normal patterning of fruit fly's offspring

Using fruit flies as a model to study embryo formation, scientists report in Nature Cell Biology that molecular breakdown of a protein called Bicoid is vital to normal head-to-tail patterning of the insect's offspring.

Time magazine declares NYSCF member as 2010 "Person who Matters" for innovative stem cell research

The New York Stem Cell Foundation extends congratulations to Derrick Rossi, PhD, a member of the inaugural class of NYSCF-Robertson Investigators, who was named one of Time Magazine's 2010 "People Who Mattered" in the December 27, 2010 Person of the Year Issue.

Therapies to target self-renewing population of chemotherapy-resistant cells needed

Leukemia patients whose cancers express higher levels of genes associated with cancer stem cells have a significantly poorer prognosis than patients with lower levels of the genes, say researchers at the Stanford University School of Medicine. The finding is among the first to show that the cancer stem cell hypothesis - which posits that some cancers spring from and are replenished by a small, hardy population of self-renewing cells - can be used to predict outcomes in a large group of patients and one day to tailor treatments in the clinic.
