Embryos with abnormalities in initial stages of pregnancy may grow into healthy babies

Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down's syndrome, suggests new research carried out in mice at the University of Cambridge. In a study published today in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing - and in many cases completely fixing - the embryo.

Study confirms involvement of immune system in CASPR2-associated encephalitis

The complement system, which forms part of our immune system, is involved in a special form of epilepsy. This is the conclusion of a recently published single-case study.

Study reveals how lipids control SH2 domain-mediated cellular protein interactions

Prof. You-Me Kim and her student Dajung Jung at Pohang University of Science and Technology, in collaboration with Prof. Wonhwa Cho's group at the University of Illinois at Chicago, have identified that the majority of human Src homology 2 (SH2) domains not only bind to proteins, but also interact with membrane lipids with high affinity and specificity.

KAIST researchers develop bio-medical imaging tool to view, analyze live cells

Professor YongKeun Park of the Physics Department at the Korea Advanced Institute of Science and Technology and his research team have developed a powerful method for 3D imaging of live cells without staining. The researchers announced the launch of their new microscopic tool, the holotomography (HT)-1, to the global marketplace through a Korean start-up that Professor Park co-founded, TomoCube.

Researchers use novel technology to sequence Y chromosome in malaria spreading mosquitoes

A team of researchers with the Fralin Life Science Institute at Virginia Tech, working with a large international consortium, has sequenced the Y chromosome--the genetic driver of sex-determination and male fertility-- in a family of malaria spreading mosquitoes.

New approach allows noninvasive identification of tumor mutations in lung cancer patients

Researchers at the Stanford University School of Medicine have devised a way to significantly increase the sensitivity of a technique to identify and sequence DNA from cancer cells circulating in a person's blood.

Low-oxygen conditions spur growth of breast cancer stem cells

Working with human breast cancer cells and mice, scientists at The Johns Hopkins University say new experiments explain how certain cancer stem cells thrive in low oxygen conditions. Proliferation of such cells, which tend to resist chemotherapy and help tumors spread, are considered a major roadblock to successful cancer treatment.

Protease inhibitors may prevent cardiovascular disease risk caused by HIV medications

According to the World Health Organization, approximately 37 million people are living with HIV. Antiviral medications are used to control the disease and prevent its progression to AIDS.

Vibration sensor helps analyze sense of touch

Type an email on your computer. Raise a glass to your lips. Feel for the light switch in a dark room. Simple, everyday tasks can demand subtle interactions between our hands and our surroundings, but, surprisingly, much remains unknown about the mechanics of the sense of touch.

New TAU study pinpoints precise mechanism that regulates inheritance of epigenetic responses

According to epigenetics -- the study of inheritable changes in gene expression not directly coded in our DNA -- our life experiences may be passed on to our children and our children's children. Studies on survivors of traumatic events have suggested that exposure to stress may indeed have lasting effects on subsequent generations. But how exactly are these genetic "memories" passed on?

Shugoshin protein maintains proper gene expression in subtelomeres

A research group discovered a new function of the chromosomal terminus, which may lead to the clarification of the mechanism for developing abnormal telomere structure such as multiple malformation and mental retardation.

Japanese scientists decode sugar molecule linked to muscular dystrophy

A group of Japanese scientists have succeeded in decoding a sugar molecule and clarifying a mechanism linked to muscular dystrophy. Their discovery has potential implications for muscular dystrophy treatment. The results of their research were published in the journal Cell Reports on February 25, 2016 EST.

Study traces ancient history of malaria evolution

A new analysis of the prehistoric origin of malaria suggests that it evolved in insects at least 100 million years ago, and the first vertebrate hosts of this disease were probably reptiles, which at that time would have included the dinosaurs.

Fertility goes down when cost of achieving social status goes up

Competition for social status may be an important driver of lower fertility in the modern world, suggests a new study published in Philosophical Transactions of the Royal Society B.

Certain gut bacteria can influence the immune system to reduce severity of stroke

Certain types of bacteria in the gut can leverage the immune system to decrease the severity of stroke, according to new research from Weill Cornell Medicine. This finding can help mitigate stroke -- which is the second leading cause of death worldwide.

CCN5 protein reverses cardiac fibrosis in heart failure models

CCN5, a matricellular protein, has been found to reverse established cardiac fibrosis in heart failure models, 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, and Woo Jin Park, PhD, Professor of Life Sciences at the Gwangju Institute of Science and Technology, South Korea.

Scientists identify two enzymes that appear to play role in metabolism, inflammation

A team led by scientists at The Scripps Research Institute and the Salk Institute for Biological Studies has discovered two enzymes that appear to play a role in metabolism and inflammation—and might someday be targeted with drugs to treat type 2 diabetes and inflammatory disorders.

UT Southwestern scientists discover mutation that causes X-linked reticulate pigmentary disorder

UT Southwestern Medical Center researchers have discovered a mutation that causes a rare systemic disorder known as X-linked reticulate pigmentary disorder (XLPDR) and, significantly, the unexpected cellular mechanism by which the mutation causes the disease.

Novel way of hitting prostate cancer

Researchers at UC Davis, in collaboration with the other institutions, have found that suppressing the nuclear receptor protein ROR-γ with small-molecule compounds can reduce androgen receptor (AR) levels in castration-resistant prostate cancer and stop tumor growth.
