May 6, 2015 — The surprising discovery and function of a new DNA modification in insects, worms, and algae has been described in a new article by an international team of ... read more

May 5, 2015 — Research results can help develop anti-inflammatory drugs, scientists say. Results from recent study revealed a nucleic acid molecule that has the perfectly reversed geometry as compared to a ... read more

May 5, 2015 — Finding out how protein-synthesizing cellular machines are assembled in a stepwise fashion has been the focus of recent research. Ribosomes are vital to the function of all living cells. Using the ... read more

Shedding Light on Rods: Novel Technique to Investigate the Activity of These Retinal Cells

May 5, 2015 — By using 'unusual' optic fibres in a novel fashion, an international team of researchers scrutinized the response to light of rods, the light-sensitive cells of the retina, and demonstrated ... read more

Scientists Dramatically Improve Method for Finding Common Genetic Alterations in Tumors

May 4, 2015 — Scientists have developed a significantly better computer tool for finding genetic alterations that play an important role in many cancers but were difficult to identify with whole-genome sequencing. ... read more

Revolutionary Method of Making RNAs

May 4, 2015 — Scientists -- and ultimately patients -- could benefit from a new approach to making ribonucleic ... read more

May 4, 2015 — Various repair mechanisms help our cells to revert continuous damage to their DNA. If they fail, mutations accumulate that can lead to devastating diseases. DNA repair defects underlie predisposition ... read more

Mutations in Two Genes Linked to Familial Pulmonary Fibrosis and Telomere Shortening

May 4, 2015 — Mutations in two genes that cause a fatal lung scarring disease known as familial pulmonary fibrosis have been identified by researchers. Researchers also determined that these mutations cause ... read more

Study Shows Where Damaged DNA Goes for Repair

May 3, 2015 — New research sheds light on the process of DNA repair in the cell. Expanded repeats of the CAG/CTG trinucleotide in yeast shift to the periphery of the cell nucleus for repair. This shift is ... read more

May 1, 2015 — The CRISPR/Cas system, which is based on chemically synthesized small RNAs and commercially available Cas9 enzyme, has enabled long gene-cassette knock-in in mice with highest efficiency ever ... read more

Researchers Create DNA Repair Map of the Entire Human Genome

May 1, 2015 — When common chemotherapy drugs damage DNA in cancer cells, the cells can't replicate. But the cells do have ways to repair the DNA and the cancer drugs aren't effective to do so. ... read more

Link Between Inherited Genetic Variations, Outcomes of Non-Small Cell Lung Cancer Patients Discovered

May 1, 2015 — Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Patients diagnosed with NSCLC have a poor prognosis, with a 5-year survival rate of only 16 percent. Researchers hope to ... read more

UV Radiations: NONO Helps to Mend the Damage

Apr. 30, 2015 — A new molecular mechanism whereby human cells protect their genome from the detrimental effect of UV radiations has been discovered by researchers. NONO is a multifunctional protein involved in ... read more

New Mechanism Controlling Cell Response to DNA Damage Discovered

Apr. 30, 2015 — DNA can be damaged by different environmental insults, such as ultraviolet light, ionizing radiation, oxidative stress or certain drugs. If the DNA is not repaired, cells may begin growing ... read more

New Cellular Response to Radiation Exposure: Must We Reconsider the Risks of Low Doses?

Apr. 30, 2015 — Almost the entire human genome is transcribed into RNA, but only a fraction of this is actually used to produce protein. The function of the majority of the RNA, the so-called 'non-coding ... read more

Researchers Use 'Knockout Humans' to Connect Genes to Disease Risk

Apr. 30, 2015 — Researchers are helping to make precision medicine a reality by sequencing entire exomes of people to assess chronic disease risk and drug efficacy. For years, scientists have been using a method ... read more

Apr. 29, 2015 — The human body is a cross between a factory and a construction zone -- at least on the cellular level. Certain proteins act as project managers, which direct a wide variety of processes and determine ... read more

Toxic Combination of Air Pollution and Poverty Lowers Child IQ

Apr. 29, 2015 — Children born to mothers experiencing economic hardship, who were also exposed during pregnancy to high levels of PAH (polycyclic aromatic hydrocarbons), scored significantly lower on IQ tests at age ... read more

Apr. 29, 2015 — Cardiomyopathies are diseases of weakened heart muscle, which can lead to heart enlargement and heart failure. The conditions are often genetically inherited. Gene therapy can clip out genetic ... read more

Apr. 29, 2015 — Biophysicists are working toward an energy-landscape theory for chromosomes. The theory could help scientists understand the genomic roots of gene regulation, DNA replication and cell ... read more
