Autoimmune response mediated by T lymphocytes may play vital role in pathogenesis of biliary atresia

Biliary atresia (BA) is an inflammatory obliterative cholangiopathy with unknown etiology, leading to progressive fibrosis and cirrhosis. Microarray technology, emerged as an indispensable research tool for gene expression profiling, has been used to study the mechanism underlying BA, and allows the simultaneous analysis of thousands of transcripts within a single experiment.

Viruses that are natural part of human genome may retrovirus culprit

A retrovirus that inserted itself into the human genome thousands of years ago may be responsible for some cases of the neurodegenerative disease amyotrophic lateral sclerosis (ALS), also known as Lou Gherig’s disease. The finding, made by Johns Hopkins scientists, may eventually give researchers a new way to attack this universally fatal condition.

Researchers study molecular mechanisms in early stages of IPN virus infection

Infectious pancreatic necrosis is a serious disease that leads to enormous losses in the salmon industry each year. The virus that causes the disease, IPN, is very prevalent in farmed salmon and trout in Norway. The virus attacks a wide diversity of hosts and has been found to occur in many different fish species, in addition to shellfish and molluscs.

Examining genetic material of egg cells may inform about embryos health

Fertility procedures such as in vitro fertilization (IVF) require a couple and the doctor to place the risky bet that the multiple eggs they choose to fertilize will produce an embryo that will thrive in the uterus. Researchers cannot biopsy eggs directly because that would destroy them, but a new discovery by professors at Brown University and Women & Infants Hospital could lead to new insights about how eggs develop and ultimately inform judgments about how the embryos they produce will fare. The idea is to examine the genetic material the egg cells discarded when they were first forming, to see which genes they were expressing.
