Scientists identify novel way of synthesising promising new antibiotic

A novel way of synthesising a promising new antibiotic has been identified by scientists at the University of Bristol. By expressing the genes involved in the production of pleuromutilin in a different type of fungus, the researchers were able to increase production by more than 2,000 per cent.

Study reveals new cell-signaling pathway that detects chromosome missegregation

A recent research study at The Hormel Institute, University of Minnesota is providing insight into the regulation of chromosome segregation and the mechanisms used by cells to prevent them from forming tumors.

Researchers identify 43 specific genes associated with both autism and cancer

Autism and cancer share more than 40 risk genes, suggesting that common mechanisms underlying the functions of some of these genes could conceivably be leveraged to develop therapies not just for cancer but for autism as well, an extensive assessment by researchers with the UC Davis MIND Institute and Comprehensive Cancer Center has found.

Riluzole drug can reverse key genetic changes linked to Alzheimer's disease

Aging takes its toll on the brain, and the cells of the hippocampus--a brain region with circuitry crucial to learning and memory--are particularly vulnerable to changes that can lead to Alzheimer's disease or cognitive decline. With the hope of counteracting the changes that can lead to these two conditions, researchers at Rockefeller University and their colleagues have begun examining the effects of a drug known to affect this circuitry.

Total cessation of GnRH production by hypothalamic neurons can lead to infertility

Individual small RNAs are responsible for controlling the expression of gonadoliberin or GnRH (Gonadotropin-Releasing Hormone), a neurohormone that controls sexual maturation, the appearance of puberty, and fertility in adults.

Researchers discover new function of genes in Fanconi anemia pathway

Researchers from UT Southwestern Medical Center have identified an important new function of genes in the Fanconi anemia pathway - a finding that could have implications for development of new therapies to treat this disorder and some cancers.

Researchers examine critical role of hypoxia in induction, amplification of FOP lesions

The cellular response to the lack of oxygen fans the flames of flare-ups in a rare bone disorder. In fibrodysplasia ossificans progressiva (FOP), a mutation triggers bone growth in muscles, which limits motion, breathing, and swallowing, among a host of progressive symptoms.

New project explores role of mosquitoes in transmission of pathogens in Austria

In the wake of climate change and globalisation, non-indigenous mosquito species establish in Europe together with the pathogens they transmit. A project funded by the Austrian Science Fund FWF is currently investigating mosquito species found in Austria and their role in the transmission of pathogens.

LJI study could provide important target for autoimmune disease interventions

Follicular helper T cells (Tfh cells), a rare type of T cells, are indispensable for the maturation of antibody-producing B cells. They promote the proliferation of B cells that produce highly selective antibodies against invading pathogens while weeding out those that generate potentially harmful ones.

Scientists discover genetic switches linked to increased lifespan in mammals

Newly discovered genetic switches that increase lifespan and boost fitness in worms are also linked to increased lifespan in mammals, offering hope that drugs to flip these switches could improve human metabolic function and increase longevity.

Hsp90 inhibitors could be effective in treating drug-resistant prostate cancers

Men with aggressive prostate cancer that has stopped responding to conventional treatment could potentially benefit from a new class of cancer drug designed to overcome drug resistance, a new study suggests.

Researchers one step closer to understanding disease origin

Researchers are one step closer to understanding the genetic and biological basis of diseases like cancer, diabetes, Alzheimer's and rheumatoid arthritis - and identifying new drug targets and therapies - thanks to work by three computational biology research teams from the University of Arizona Health Sciences, University of Pennsylvania and Vanderbilt University.

Small doses of cancer drug may be potential treatment for sepsis and other pandemics

Results from laboratory experiments and mouse studies suggest that small doses of drugs from a specific class of approved cancer medications called topoisomerase 1 (top1) inhibitors may protect against the overwhelming immune response to infection that sometimes leads to sepsis, a bacterial condition that kills as many as 500,000 people in the United States each year.

Novel gene therapy can treat pulmonary hypertension linked with heart failure

Scientists have used a novel gene therapy to halt the progression of pulmonary hypertension, a form of high blood pressure in the lung blood vessels that is linked to heart failure, according to a study led by Roger J. Hajjar, MD, Professor of Medicine and Director of the Cardiovascular Research Center at the Icahn School of Medicine at Mount Sinai.

Study provides new avenues for improving quality, stability of embryonic stem cells

Research led by the Babraham Institute with collaborators in the UK, Canada and Japan has revealed a new understanding of how an open genome structure supports the long-term and unrestricted developmental potential in embryonic stem cells. This insight provides new avenues for improving the quality and stability of embryonic stem cells - an essential requirement to fulfil their promise in regenerative medicine.

Scientists reprogram mature blood cells from mice into blood-forming HSCs

Researchers at Boston Children's Hospital have reprogrammed mature blood cells from mice into blood-forming hematopoietic stem cells (HSCs), using a cocktail of eight genetic switches called transcription factors. The reprogrammed cells, which the researchers have dubbed induced HSCs (iHSCs), have the functional hallmarks of HSCs, are able to self-renew like HSCs, and can give rise to all of the cellular components of the blood like HSCs.

Machine learning could become powerful tool in plastic surgery

With an ever-increasing volume of electronic data being collected by the healthcare system, researchers are exploring the use of machine learning—a subfield of artificial intelligence—to improve medical care and patient outcomes.

New research reveals sliding ability of cancer cells that helps in tumor spread

Metastasis. The very word evokes fear. Defined as the spread of cancer cells from one part of the body to another, metastasis is the cause of approximately 90 percent of deaths among cancer patients. How does metastasis come about? And can we stop it? New research from a team led by Northeastern's Anand Asthagiri, associate professor of bioengineering and chemical engineering, helps to answer those questions. It provides an astonishing look at the biophysical properties that permit breast cancer cells to "slide" by obstales and travel out of their primary tumor toward a blood vessel that will carry them to a new site.

New gene testing method can identify mutations, prioritize variants in breast and ovarian cancer genes

A research team led by an award-winning genomicist at Western University has developed a new method for identifying mutations and prioritizing variants in breast and ovarian cancer genes, which will not only reduce the number of possible variants for doctors to investigate, but also increase the number of patients that are properly diagnosed.

Studies on role of vitamin A in heart health have drawn opposite conclusions

Vitamin A is involved in many bodily processes, including vision and skin health, but its role in the heart is unclear. While vitamin A is critical for heart development of embryos—vitamin A deficiency during pregnancy leads to an abnormal heart and prenatal death—studies on vitamin A's role in heart health have drawn opposite conclusions.
