Viral RNA linked to human immune response

In its fight against an intruding virus, an enzyme in our immune system may sense certain types of viral RNA pairs, according to scientists.

Discovery of mechanism that protects somatic cells against the behaviour of germ cells

An IRB Barcelona research team discovers the mechanism that favors the correct separation of germ cells -- future ovules and sperm -- from the rest of the cells during embryonic development

Epigenetic signature changes in low oxygen levels may contribute to prostate cancer development

UCD Conway researchers have characterised epigenetic signature changes in prostate cells under conditions of low oxygen levels that may lead to tumour development.

Malaria vaccine in the pipeline

Australian scientists have developed the first genetically-engineered malaria vaccine and the vaccine will be trialled in humans early next year.

World's first genetically-modified strain of malaria parasite

Walter and Eliza Hall Institute scientists have created a weakened strain of the malaria parasite that will be used as a live vaccine against the disease. The vaccine, developed in collaboration with researchers from the US, Japan and Canada, will be trialled in humans from early next year.

Gene expression patterns in cancer could aid early screening and prevention

Distinctive patterns of genes turned off - or left on - in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them, Medical College of Georgia scientists say.

UT Southwestern Medical Center grant aids study of lung cancer in people who never smoked

Researchers at UT Southwestern Medical Center are among an elite group of cancer scientists to share a $2 million grant to find biomarkers for lung cancer that develops in people who have never smoked.

A quantum dot-based method for analysis of DNA methylation

One of the earliest events that changes a normal cell into a malignant one is known as deoxyribonucleic acid (DNA) hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes.

Discovery of gene linked to follicular lymphoma

California and Arizona researchers have identified a gene variant that carries nearly twice the risk of developing an increasingly common type of blood cancer, according to a study published online today by the science journal Nature Genetics.

Scientists develop process for 'surgical' genetic changes

Research led by scientists at Iowa State University's Plant Sciences Institute has resulted in a process that will make genetic changes in plant genes much more efficient, practical and safe.

New understanding on mechanisms of DNA replication and transcription

By manipulating individual atoms in DNA and forming unique molecules, a Georgia State University researcher hopes to open new avenues in research towards better understanding the mechanisms of DNA replication and transcription, and perhaps leading to new treatments for diseases.

Discovery of genetic trigger for disease-fighting antibodies

A research team led by the La Jolla Institute for Allergy & Immunology has identified the specific gene which triggers the body to produce disease-fighting antibodies -- a seminal finding that clarifies the exact molecular steps taken by the body to mount an antibody defense against viruses and other pathogens.

Discovery of five genetic variants related to blood pressure in African-Americans

A team led by researchers from the National Institutes of Health (NIH) has reported the discovery of five genetic variants related to blood pressure in African-Americans, findings that may provide new clues to treating and preventing hypertension. The effort marks the first time that a relatively new research approach, called a genome-wide association study, has focused on blood pressure and hypertension in an African-American population.

Estrogen can reduce stroke damage by inactivating a tumor-suppressing protein

Estrogen can halt stroke damage by inactivating a tumor-suppressing protein known to prevent many cancers, Medical College of Georgia researchers say.

Genome sequencing of schistosomiasis parasites could promote drug development

Researchers have sequenced the genomes of two parasites that cause bilharzia or schistosomiasis - a disease transmitted by water-borne snails that affects more than 200 million people worldwide - "revealing potential weaknesses that could be exploited by drug developers," Nature reports (Smith, 7/15).

Research reveals major genetic differences between blood and tissue cells

Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell. Their results appear in the July issue of the journal Human Mutation.

New research tool – map of genomic variation for diagnosing and identifying genetic problems

Genetics researchers have unveiled a powerful new resource for scientists and health providers studying human illnesses -- a reference standard of deletions and duplications of DNA found in the human genome. Drawn from over 2,000 healthy persons, the study provides one of the deepest and broadest sets of copy number variations (CNVs) available to date, along with a new research tool for diagnosing and identifying genetic problems in patients.

Discovery of brain-protecting protein

Johns Hopkins researchers have discovered a novel protein that can protect brain cells by interrupting a naturally occurring "stress cascade" resulting in cell death.

Researchers map how staph infections alter immune system

Infectious disease specialists at UT Southwestern Medical Center have mapped the gene profiles of children with severe Staphylococcus aureus infections, providing crucial insight into how the human immune system is programmed to respond to this pathogen and opening new doors for improved therapeutic interventions.

Dramatic drop in deaths from most common cancers

The death toll from three of the UK's most common cancers has dropped to its lowest level for almost 40 years* - according to new figures released by Cancer Research UK.
