New Cockayne syndrome discovery

Scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have shown that the genetic defect that causes Cockayne Syndrome affects a key function of the cell – the transcription of genes coding for ribosomal RNA.

Effectiveness of mouse breeds that mimic Alzheimer's disease symptoms questioned

Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease (AD) may not be as effective as previously assumed.

Genomic factors may play a role in alcohol and tobacco use

Alcohol and smoking can be harmful, if not deadly. While the desire for these substances can be due to environmental cues, genomic factors also play an important role.

Cause of major subtype of glaucoma discovered

In a paper published in the journal Science, scientists from deCODE genetics and academic colleagues from the National University Hospital in Reykjavik and Uppsala University in Sweden report the discovery of two common single letter variations (SNPs) in the sequence of the human genome that appear to account for virtually all cases of a major subtype of glaucoma.

Chromatin remodeling complex connected to DNA damage control

When molecular disaster strikes, causing structural damage to DNA, players in two important pathways talk to each other to help contain the wreckage, scientists at The University of Texas M. D. Anderson Cancer Center report in the August edition of Cell.

TRF2 and POT1 proteins found on telomeres control DNA damage response pathways

No sooner had cells evolved linear chromosomes than they had a life-threatening problem to solve.

Gender differences in renal and other genes contributing to blood pressure

Many common diseases exhibit gender bias and gender differences have been observed in the development of high blood pressure (hypertension) and heart (cardiovascular) disease.

New research may lead to future gene therapies for patients with sickle cell anemia and beta-thalassemia

Virginia Commonwealth University researchers studying hemoglobin genes, mutations of which play a role in genetic blood disorders like sickle cell anemia and beta-thalassemia, have identified two proteins that are responsible for regulating overlapping groups of genes during the development of red blood cells.

Scientists discover the dynamics of transcription in living mammalian cells

Transcription the transfer of DNA's genetic information through the synthesis of complementary molecules of messenger RNA forms the basis of all cellular activities.

Mechanistic model of DNA repair

Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer.

New insight into mechanism of DNA-break repair

A new UC Davis study that explains the actions of a gene mutation that causes early onset cancer provides a fundamental insight into the mechanism of DNA-break repair.

Biologists discover one reason why chromosomes break, often leading to cancer

In the past ten years, researchers in genome stability have observed that many kinds of cancer are associated with areas where human chromosomes break.

Discredited Korean embryonic stem cells' true origins revealed

A report from researchers at Children's Hospital Boston and the Harvard Stem Cell Institute sheds new light on a now-discredited Korean embryonic stem cell line, setting the historical record straight and also establishing a much-needed set of standards for characterizing human embryonic stem cells.

Detection of gene fusions in prostate cancer

Researchers at the University of Michigan Comprehensive Cancer Center have discovered how genes turn on the switch that leads to prostate cancer.

Prototype vaccine against tuberculosis

Using a novel approach, researchers at the Albert Einstein College of Medicine of Yeshiva University have developed a prototype vaccine against tuberculosis (TB) that works better in animal models than the only TB vaccine now available.

Aggressive therapy best for certain acute myeloid leukemia patients

A new study suggests that acute leukemia patients whose cancer cells show a genetic change that usually predicts a swift return of the disease following remission may remain disease-free longer when given aggressive therapy.
