Rituxan in combination with chemo improves survival in chronic lymphocytic leukemia

Genentech, Inc. and Biogen Idec have announced that two global Phase III studies in chronic lymphocytic leukemia (CLL), CLL8 and REACH, showed Rituxan (rituximab) plus chemotherapy significantly increased the time patients lived without their disease advancing, as defined by the primary endpoint of progression-free survival (PFS), when compared to chemotherapy alone.

Study links cone death in retinitis pigmentosa to metabolic problem

Rods and cones coexist peacefully in healthy retinas. Both types of cells occupy the same layer of tissue and send signals when they detect light, which is the first step in vision.

Scientists find 12 new genes with potential as drug targets

Scientists have identified 12 new genes that are somewhat strange bedfellows: Some link gallstones and blood cholesterol levels, others link melatonin and sleep patterns to small increases in glucose levels and larger jumps in the risk of diabetes.

Scientists create infectious prion disease in mouse model

A worldwide group of scientists has created an infectious prion disease in a mouse model, in a step that may help unravel the mystery of this progressive disease that affects the nervous system in humans and animals.

Genes for nine health indicators: Population study finds genetics clues

A new genome-wide study examines genetic variants associated with nine metabolic traits and is the first to draw out novel variants from a population unselected for current disease. The traits are indicators for common disease such as cardiovascular disease, type 2 diabetes, blood pressure, inflammation and lipid levels.

Study finds six genetic variants associated with 'bad' cholesterol

A new study presages a real aim of genetics: to look at whole populations to in order determine the significance of individual genetic variants for individual health. The research team, whose work is published in Nature Genetics, find six novel genetic variants that are associated with lipid levels, a common indicator of heart or artery disease.

Body clock and sleep patterns linked to diabetes and high blood sugar

Diabetes and high levels of blood sugar may be linked to abnormalities in a person's body clock and sleep patterns, according to a genome-wide association study published today in the journal Nature Genetics.

Zinc key to formation of hospital-acquired infections

Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of Americans.

Breakthrough in understanding the phenomenon of nucleolar dominance

Since the machinery involved in nucleolar dominance is some of the same machinery that can go haywire in diseases such as cancer, Pikaard and his collaborators' research may have important implications for applied medical research.

Discovery of groundbreaking technique for body to accept gene therapy

Researchers at Columbia University Medical Center and the State University of New York at Stony Brook (SUNY) have developed a groundbreaking technique to sneak therapeutic genes past the body's defenses, possibly clearing one of the largest hurdles to realizing the potentials of medically altering a patient's DNA.

New insights into cell division

Biologists have discovered a mechanism that is critical to cytokinesis -- nature's completion of mitosis, where a cell divides into two identical daughter cells.

Breakthrough in sickle cell disease and thalassemia research

Researchers have identified a gene that directly affects the production of a form of hemoglobin that is instrumental in modifying the severity of the inherited blood disorders sickle cell disease and thalassemia.

Model unravels rules that govern how genes are switched on and off

For years, scientists have struggled to decipher the genetic instruction book that details where and when the 20,000 genes in a human cell will be turned on or off.

Metabolic reactions: Less is more in single-celled organisms

A Northwestern University study has found a surprising similarity among four quite different organisms.

Genetic ancestry of African-Americans reveals new insights about gene expression

The amount of proteins produced in cells—a fundamental determinant of biological outcomes collectively known as gene expression—varies in African American individuals depending on their proportion of African or European genetic ancestry.

Chromatin packaging helps decipher how cancer develops

To decipher how cancer develops, Johns Hopkins Kimmel Cancer Center investigators say researchers must take a closer look at the packaging.

Researchers focus on phosphoinositide 3-kinase pathway in cancer research

Researchers are taking a closer look at the phosphoinositide 3-kinase (PI3-kinase) pathway as studies continue to demonstrate that inhibiting this biological route suppresses tumor growth, reports Genetic Engineering & Biotechnology News (GEN ).

Stem cells derived from bone marrow may offer novel therapeutic option for epidermolysis bullosa

Stem cells derived from bone marrow may serve as a novel therapeutic option to treat a disease called epidermolysis bullosa (EB), a disorder characterized by extraordinarily fragile skin, according to a study prepublished online in Blood, the official journal of the American Society of Hematology.
