Rapamycin is a drug used to prevent the rejection of organ and bone marrow transplants by the body. Rapamycin is an antibiotic that blocks a protein involved in cell division and inhibits the growth and function of certain T cells of the immune system involved in the body's rejection of foreign tissues and organs. It is a type of immunosuppressant and a type of serine/threonine kinase inhibitor. Rapamycin is now called sirolimus.
Scientists at the University of Illinois have found that free fatty acids in the blood appear to boost proliferation and growth of breast cancer cells. The finding could help explain obese women's elevated risk of developing breast cancer after menopause.
Dr. Alan Green's patients travel from around the country to his tiny practice in Queens, N.Y., lured by the prospect of longer lives.
In a strategic search, Johns Hopkins scientists created and screened a library of 45,000 new compounds containing chemical elements of widely used immune system suppressants, and say they found one that may prevent reperfusion injury, a tissue-damaging and common complication of surgery, heart attack and stroke.
Renowned Harvard University geneticist David Sinclair recently made a startling assertion: Scientific data shows he has knocked more than two decades off his biological age
New information is unfolding on the genetic controls of an early turning point in pregnancy. As the tiny, dividing cell mass, the blastocyst, travels from the oviduct and lodges in the wall of the uterus, the cells must exit their pre-implantation state and be ready for post-implantation development.
Chronic kidney disease is a global health concern, affecting about 10 percent of the world's population--and increasing in prevalence. A final, common pathway in chronic kidney disease is fibrosis.
Pseudoachondroplasia (PSACH) is a severe inherited dwarfing condition characterized by disproportionate short stature, joint laxity, pain, and early onset osteoarthritis.
A team of researchers led by Principal Investigator Dr Jan Gruber from Yale-NUS College has discovered a combination of pharmaceutical drugs that not only increases healthy lifespan in the microscopic worm Caenorhabditis elegans (C. elegans), but also delays the rate of ageing in them, a finding that could someday mean longer, healthier lives for humans.
We've all experienced a "gut feeling" -- when we know deep down inside that something is true. That phenomenon and others (like "butterflies in the stomach") aptly describe what scientists have now demonstrated: that the gut and the brain are more closely connected than we once thought, and in fact the health of one can affect the other.
A team of researchers at the Icahn School of Medicine at Mount Sinai and the University of Washington has designed a modeling system that integrates genomic and temporal information to infer causal relationships between genes, drugs, and their environment, allowing for a more accurate prediction of their interactions over time.
New research on autism has found, in a mouse model, that drug treatment at a young age can reverse social impairments. But the same intervention was not effective at an older age.
A new federally-funded research project at the Ohio University Edison Biotechnology Institute and Heritage College of Osteopathic Medicine could lead to treatments that extend human lifespan and allow people to enjoy better health in their old age.
MATCHA, the Green Tea packed with antioxidants, is often hailed as containing properties which prevent disease.
Researchers at the University of Cincinnati College of Medicine have discovered that cell metabolism plays an important role in the ability of cells to start a survival program called autophagy, an unwanted side effect of some anti-cancer drugs that helps some tumor cells dodge treatment and eventually regrow into new tumors.
Pediatric researchers have identified a gene mutation that causes a serious lymphatic condition, and used that knowledge to restore normal lymphatic vessels in model animals. The laboratory findings may lead to a new therapy for patients with this type of abnormal lymphatic circulation.
Autophagy is a process of destruction and processing of damaged cell components by the cells themselves. It is used by a cell to clean itself of excessive organelles and sometimes for self-execution. This adaptive mechanism supports a healthy phenotype on the cellular level.
The rise of genomics, the shift from considering genes singly to collectively, is adding a new dimension to medical care; biomedical researchers hope to use the information contained in human genomes to make better predictions about individual health, including responses to therapeutic drugs.
Focal malformations of cortical development are a heterogeneous group of brain cortical abnormalities.
James McNew's and Michael Stern's biochemical hunt for the root cause of a rare, paralyzing genetic disorder is a 10-year quest that's taken an unexpected turn toward everyday killers such as Alzheimer's disease, cancer and aging.
Scientists report finding a potentially promising treatment target for aggressive and deadly high-grade brain cancers like glioblastoma. But they also say the current lack of a drug that hits the molecular target keeps it from being advanced for testing as a therapeutic strategy for patients with few treatment options.
