Research Team Creates Model to Predict Cellular Evolution

Aug. 31, 2015 — Scientists have not been able to understand and predict how cells evolve in our bodies, and this process is important because evolving cell populations are at the core of drug-resistant infections ... read more

Aug. 31, 2015 — From 1952, DNA was sequenced, modified and extensively studied, but no technique was able to produce clear direct images of DNA. Now, researchers have developed a new technique to produce a direct ... read more

Aug. 28, 2015 — Researchers have for the first time created and used a nanoscale vehicle made of DNA to deliver a CRISPR-Cas9 gene-editing tool into cells in both cell culture and an animal ... read more

Aug. 28, 2015 — A growing, dividing cell uses most of its energy store to make its "protein factories," the ribosomes. An important player in their "assembly" is the exosome, a molecular ... read more

Aug. 28, 2015 — Researchers have unraveled a role for tumor suppressor genes in restricting the growth of neighboring cell populations. The study might have implications for understanding the early events of ... read more

Scientists Identify Possible Key in Virus, Cancer Research

Aug. 27, 2015 — Scientists have uncovered a viral protein in the cell that inhibits the major DNA sensor and thus the body's response to viral infection, suggesting that this cellular pathway could be ... read more

HIV Particles Do Not Cause AIDS, Our Own Immune Cells Do

Aug. 27, 2015 — Scientists have discovered that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. In a new ... read more

Aug. 27, 2015 — RNA can be translated into protein or transformed into gene-regulating molecules. A newly discovered 'reader' protein recognizes a chemical instruction tag affixed to RNA, an important step ... read more

Researchers Thwart Cancer Cells by Triggering 'Virus Alert'

Aug. 27, 2015 — Working with human cancer cell lines and mice, researchers have found a way to trigger a type of immune system 'virus alert' that may one day boost cancer patients' response to ... read more

Circadian Genes Go to Sleep Every Day at the Periphery of the Nucleus

Aug. 27, 2015 — Mobility between different physical environments in the cell nucleus regulates the daily oscillations in the activity of genes that are controlled by the internal biological clock, according to a new ... read more

Aug. 27, 2015 — Researchers show how DNA repair proteins sound the alarm to threats, pointing to a novel cancer ... read more

Aug. 27, 2015 — A finding reveals why the transformation process of differentiated cells into stem cells results in significant damage to the DNA. Researchers have managed to rectify this damage using a simple ... read more

Aug. 27, 2015 — More than a cause of a simple infection, viruses are often involved in the development of serious diseases. Such is the case with liver cancer, which often develops in an organ that has been weakened ... read more

Trypanosomes and Renal Insufficiency: APOL1 Induces a Double Permeabilization

Aug. 27, 2015 — Scientists shed further light on the way human APOL1 kills the ... read more

New Strategy Improves Detection of Genetic Mutations in Hereditary Colorectal Cancer

Aug. 27, 2015 — Enhanced accuracy and reduced turnaround time of testing can provide vital information for patients suspected of having lynch syndrome and their family members, according to a new ... read more

New 'Mutation-Tracking' Blood Test Could Predict Breast Cancer Relapse Months in Advance

Aug. 26, 2015 — Scientists have developed a blood test for breast cancer able to identify which patients will suffer a relapse after treatment, months before tumors are visible on hospital scans.The test can uncover ... read more

Aug. 26, 2015 — Researchers say they have discovered some of the first steps in how a very common gene mutation causes the brain damage associated with both amyotrophic lateral sclerosis (ALS) and frontotemporal ... read more

Batting Practice in the Genome

Aug. 25, 2015 — In the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players. But scientists have now found that spectator proteins ... read more

Adaptive Mutation Mechanism May Explain Some Forms of Antibiotic Resistance

Aug. 25, 2015 — Evolutionary theory says mutations are blind and occur randomly. But in the phenomenon of adaptive mutation, cells can peek under the blindfold, increasing their mutation rate in response to stress. ... read more

Aug. 25, 2015 — When our cells copy their DNA to grow and replicate, it’s vital the process runs smoothly. To get this right, cells use a complex “machine”, made from many hundreds of ... read more
