Genetic variation in metabolism identified

Metabolic diseases - in particular the increasingly prevalent type 2 diabetes - are caused by a complex interaction between genetic disposition and unfavorable lifestyle, above all unbalanced diet and too little physical exercise.

Diet rich in fat, sugar and cholesterol a potential risk factor for Alzheimer's disease

Mice that were fed a diet rich in fat, sugar and cholesterol for nine months developed a preliminary stage of the morbid irregularities that form in the brains of Alzheimer's patients.

Study identifies genetic variants giving rise to differences in metabolism

Common genetic polymorphisms induce major differentiations in the metabolic make-up of the human population, according to a paper published November 28 in the open-access journal PLoS Genetics.

Researchers discover genomic causes of acute lymphoblastic leukemia relapse

Scientists at St. Jude Children's Research Hospital have identified distinctive genetic changes in the cancer cells of children with acute lymphoblastic leukemia (ALL) that cause relapse.

Protein-misfolding accelerates yeast evolution

Under stress, yeast cells can unleash a remarkable mechanism based on protein-misfolding that gives them new characteristics without requiring genetic mutations.

Condensin II proteins found to keep chromosomes apart when necessary

If chromosomes snuggle up too closely at the wrong times, the results can be genetic disaster.

Discovery of new way in which epigenetic information is inherited

Hereditary information flows from parents to offspring not just through DNA but also through the millions of proteins and other molecules that cling to it.

Researchers provide new evidence that aging can be slowed

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age.

Scientists uncover new RNA processing mechanism and a new class of small RNAs

A very small fraction of our genetic material - about 2% - performs the crucial task scientists once thought was the sole purpose of the genome: to serve as a blueprint for the production of proteins, the molecules that make cells work and sustain life.

Discovery of mechanism linking serotonin with regulation of food intake

Genetic mouse models have provided surprising insight into mechanisms linking serotoninergic compounds with the regulation of feeding behavior and body weight.

Genomics and bioinformatics could be the future in battle against malaria

Malaria, one of the oldest diseases known to man, has shown no signs of slowing down as it ages.

Mouse model of prion disease mimics diverse symptoms of human disorder

A comprehensive mouse model of inherited prion disease exhibits cognitive, motor, and neurophysiological deficits that bear a striking resemblance to the symptoms experienced by patients with the human version of "mad cow disease," Creutzfeldt-Jakob disease (CJD).
