UB researchers express concern about a new variant of Klebsiella pneumoniae

University at Buffalo researchers are expressing concern about a new, under-recognized, much more potent variant of a common bacterium that has surfaced in the U.S.

RAD51 gene behind the cause of congenital mirror movements

Further work carried out on mice suggests that this gene plays a part in motor network cross-over. Cross-over is a key factor in the transmission of brain signals, because it allows the right side of the brain to control the left side of the body and vice versa. This research has been published in The American Journal of Human Genetics.

Study reveals immune mechanism for surveillance over EBV infection

Some 90 percent of people are exposed to the Epstein Barr virus (EBV) at some point in their life. Even though it is quickly cleared from the body, the virus can linger silently for years in small numbers of infected B cells.

Evolutionary biologist receives LRI grant for lupus research

Evolutionary biologist Harmit Singh Malik, Ph.D., of Fred Hutchinson Cancer Research Center, has received a $300,000 grant from the Lupus Research Institute to study the potential role of "genetic conflicts" in the development of lupus, an autoimmune disease.

Scientists observe maturation of immune cells in live zebrafish embryos

T-cells are the immune system's security force. They seek out pathogens and rogue cells in the body and put them out of action. Their precursors are formed in the bone marrow and migrate from there into the thymus. Here, they mature and differentiate to perform a variety of tasks. Scientists at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded for the first time in observing the maturation of immune cells in live zebrafish embryos.

Abcodia, Volition announce collaboration agreement

VolitionRX Limited, a life sciences company focused on developing blood-based diagnostic tests, announces a collaboration agreement with Abcodia, a specialist company spun out from University College London (UCL), under which Volition will gain access to Abcodia's biobank of over 5,000,000 human serum samples to validate its suite of NuQ tests.

Scientists discover molecular pathway by which maternally inherited deafness appears to occur

Yale scientists have discovered the molecular pathway by which maternally inherited deafness appears to occur: Mitochondrial DNA mutations trigger a signaling cascade, resulting in programmed cell death.

New technology opens up pathways for disease cures

The understanding of diseases such as Parkinson's and Alzheimer's is set to take a step forward following groundbreaking technology at which will enable cell analysis using automated 3D microscopy.

New UTA method shows promise against heart disease

University of Texas at Austin researchers have demonstrated a new and more effective method for regrowing blood vessels in the heart and limbs - a research advancement that could have major implications for how we treat heart disease, the leading cause of death in the Western world.

Study reveals new guiding principles for cancer genomics

That our chromosomes can break and reshuffle pieces of themselves is nothing new; scientists have recognized this for decades, especially in cancer cells. The rules for where chromosomes are likely to break and how the broken pieces come together are only just now starting to come into view.

New potential strategy for KRAS-mutant colon cancers

Researchers from the Massachusetts General Hospital (MGH) Cancer Center have identified a new potential strategy for treating colon tumors driven by mutations in the KRAS gene, which usually resist both conventional and targeted treatments.

Study describes how multiple RNA binding proteins cooperatively control genetic splicing code

Understanding how RNA binding proteins control the genetic splicing code is fundamental to human biology and disease - much like editing film can change a movie scene. Abnormal variations in splicing are often implicated in cancer and genetic neurodegenerative disorders.

Glial cells inhibit growth of brainstem neurons

Researchers at Oregon Health & Science University have discovered that brain cells commonly thought to play a supporting role actually are critically important for the growth of brainstem neurons responsible for cardiorespiratory control. The discovery has profound implications for the prevention and treatment of SIDS (Sudden Infant Death Syndrome), the leading cause of death in children aged one month to one year.

University of Georgia researcher to develop first Chagas vaccine for pets

Chagas disease is the single most common cause of congestive heart failure and sudden death in the world. The devastating parasitic infection affects millions of people throughout Central and South America. But as global travel increases, it's becoming a greater threat in the United States and Europe as well.

Study details how breast tumors may flip TGF-beta signalling switch

Signals can tell cells to act cancerous, surviving, growing and reproducing out of control. And signals can also tell cells with cancerous characteristics to stop growing or to die. In breast cancer, one tricky signal called TGF-beta does both - sometimes promoting tumors and sometimes suppressing them.

Study: 3D organization of chromosomes plays a role in cancer genomics

It is well understood that chromosomal translocation - a process whereby pieces of two chromosomes break off and exchange places - is a hallmark of many cancers including leukemia, thyroid cancer and lymphoma and play an important part in how healthy cells become cancerous. The role spatial proximity plays in why certain chromosomal translocations happen repeatedly, however, has been a long-standing area of debate among scientists.

Researchers sequence genome of Tasmanian devil contagious cancer

Researchers have sequenced the genome of a contagious cancer that is threatening the Tasmanian devil, the world's largest carnivorous marsupial, with extinction. Cataloguing the mutations present in the cancer has led to clues about where the cancer came from and how it became contagious.

Scientists create first 3-D living tissue model of glioma

Brown University scientists have created the first three-dimensional living tissue model, complete with surrounding blood vessels, to analyze the effectiveness of therapeutics to combat brain tumors. The 3-D model gives medical researchers more and better information than Petri dish tissue cultures.

New preclinical data from Regulus' miR-21 study on kidney fibrosis

Regulus Therapeutics Inc., a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, today announced that new preclinical data investigating the role of microRNA-21 (miR-21) in the treatment of kidney fibrosis has been published in the journal Science Translational Medicine.

New genetic resource to accelerate development of novel treatments for diseases

A new genetic resource from an international research consortium is expected to accelerate the development of new cures and treatments for a wide range of human diseases. This project, called the mouse "Collaborative Cross" (CC) resource, will increase the likelihood that experiments conducted in mice will advance our understanding of human biology.
