Protein vital for cell survival and immune balance has another form with different function

Research led by St. Jude Children's Research Hospital investigators suggests that safeguarding cell survival and maintaining a balanced immune system is just the start of the myeloid cell leukemia sequence 1 (MCL1) protein's work.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Researchers discover small molecules that kill HPV-infected cancer cells

Researchers at The Wistar Institute announce the discovery of small molecules that kill cancer cells caused by infection with human papillomavirus (HPV). Their results, in both cell and mouse models, demonstrate that the small molecule inhibitors protect a tumor-suppressing protein targeted by viral proteins, thus killing the infected tumor cells.

University of Kentucky researchers make major breakthrough in GA

University of Kentucky researchers, led by Dr. Jayakrishna Ambati, have made a major breakthrough in the "dry" form of age-related macular degeneration known as geographic atrophy.

Study shows how PCBs could add to autism risk

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites - the filament-like projections that conduct electrochemical signals between neurons - and disrupts normal patterns of neuronal connections in the brain.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.

Positive results from Repligen's RG3039 Phase 1 study for spinal muscular atrophy

Repligen Corporation today announced positive results from a Phase 1 study to evaluate the pharmacokinetic (PK) and safety profile of RG3039, a novel small molecule drug candidate for the potential treatment of spinal muscular atrophy (SMA).

Non-coding RNA gives off biological signals during viral infection

Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) - RNA molecules that do not translate into proteins - play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.

PET/CT could help improve prediction of heart attack

An award-winning research project, funded by the British Heart Foundation (BHF), has tested a new imaging method which could help improve how doctors predict a patient's risk of having a heart attack.

Researchers describe novel mechanism of HIV-1 spread by dendritic cells

A new understanding of the initial interactions of human immunodeficiency virus type 1 (HIV-1) and dendritic cells is described by Boston University School of Medicine (BUSM) researchers in a study currently featured in the Proceedings of the National Academy of Sciences.

Cancer therapy with common cold virus

Common viruses have become the latest weapon against cancer. There is the case of the eight-year-old African boy diagnosed with Burkitt's lymphoma at a Ugandan health clinic. He was exposed to the measles virus and in the next few weeks his tumour regressed completely and he entered remission. But only relatively recently have scientists clinically examined the interaction between viruses and cancers in the growing area of oncolytic virotherapy.

TopBP1 protein prevents early brain cells from DNA damage

St. Jude Children's Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer.

Nano-devices cross blood-brain barrier to deliver drug to treat cerebral palsy

A team of scientists from Johns Hopkins and elsewhere have developed nano-devices that successfully cross the brain-blood barrier and deliver a drug that tames brain-damaging inflammation in rabbits with cerebral palsy.

Mod5 yeast prion contributes to cell survival under environmental stress

One of the greatest mysterious in cellular biology has been given a new twist thanks to findings reported in Science. Researchers at the RIKEN Brain Science Institute show that prions, proteins that transmit heritable information without DNA or RNA, can contribute to drug resistance and cellular adaptation. Their discovery of a yeast prion with these properties demonstrates the active role of the prion conversion in cellular fitness adaptation, providing new insights into the potentially broader function of prions in living organisms.

APS honors MCW professor with Henry Pickering Bowditch Lecture Award

High blood pressure, or hypertension, is a major problem worldwide, with the latest estimates suggesting that a billion people across the globe may have this condition. Hypertension not only takes an enormous cost on health and wellbeing, but it also exacts an expensive financial toll. Complications from this condition including kidney disease, and its resulting treatments, such as long-term dialysis and kidney transplant, are some of the costliest conditions the American health care system must contend with.

Autophagy potential target for new CF treatments

Scientists have found why a certain type of bacteria, harmless in healthy people, is so deadly to patients with cystic fibrosis.
