Autism caused by hundreds of different genetic mutations: Study

New research shows that autism is not caused by one or two gene defects but probably by hundreds of different mutations, many of which arise spontaneously. This comes from the study that has examined the genes of more than 1,000 families.

Single molecule telomerase activator could extend human cell life indefinitely

When expressed (turned on), the gene (hTERT) located on Chromosome number 5p15.33 activates the enzyme telomerase. Human cells can keep living and dividing indefinitely when telomerase is continually present; i.e. the cells become immortal. Telomerase Activation Sciences, Inc. (T.A. Sciences®) announces TA-65® can extend human cell life indefinitely. TA-65® is a single molecule telomerase activator that turns on the Immortality Gene under controlled laboratory conditions.

Increased blood clotting tendency linked to elevated bowel cancer risk

Back in the mid 19th century, a French doctor, Armand Trousseau, discovered a connection between cancer and thrombosis - the formation of often dangerous blood clots that can lead to venous occlusion.

Scientists identify chromosomal mutation responsible for excessive hair growth

Researchers in the Keck School of Medicine of the University of Southern California (USC), together with scientists in Beijing, China, have discovered a chromosomal mutation responsible for a very rare condition in which people grow excess hair all over their bodies.

SMPX gene mutation causes hereditary hearing impairment

Excessive noise is not the only thing that causes damage to hearing. In many cases, genetic factors are responsible for the loss of hearing at a young age. Researchers at the Max Planck Institute for Molecular Genetics in Berlin together with colleagues from Nijmegen have discovered a previously unknown genetic cause of progressive hearing impairment: the disease is caused by mutations of the SMPX gene, which is located on the X chromosome.

Study finds novel site within MS4A gene cluster, confirms presence of SNP linked with Alzheimer's

Recently the number of genes known to be associated with Alzheimer's disease has increased from four to eight, including the MS4A gene cluster on chromosome 11.

Lipidomic profiling can lead to better and earlier prediction of major diseases

Studying the genetic make-up of different varieties of lipids in the blood plasma of an individual can lead to a better and earlier prediction of diseases such as diabetes, atherosclerosis, and heart disease, two researchers will tell the annual conference of the European Society of Human Genetics today.

Karolinska researchers study four siblings affected by early-onset Alzheimer's disease

Four siblings in a family affected by early-onset Alzheimer's have been studied by a group of researchers at Karolinska Institutet in Sweden. This has been a unique opportunity to make comparative studies and to monitor the development of the disease over a prolonged period of time.

New combination therapy eradicates acute lymphoblastic leukemia in children, older adults

In a significant breakthrough, investigators at Weill Cornell Medical College and the University of California, San Francisco, have been able to overcome resistance of a form of leukemia to targeted therapy, demonstrating complete eradication of the cancer in cell and animal studies.

Researchers devise new genetic technique for IVF embryos

Researchers at the Johns Hopkins University School of Medicine have devised a new technique, which helps couples that are affected by or are carriers of genetic diseases have in vitro fertilized babies free of both the disease in question and other chromosomal abnormalities. The results were reported in the April issue of Fertility and Sterility.

Scientists mimic dyskeratosis congenita through study of undifferentiated iPS cells

A rare genetic disease called dyskeratosis congenita, caused by the rapid shortening of telomeres, can be mimicked through the study of undifferentiated induced pluripotent stem cells, according to new findings from the Stanford University School of Medicine.
