Precise Timing Enabled Pig-to-rat Transplants To Cure Diabetes

... primordia into diabetic rats cures their diabetes permanently without the need for immune suppression. The pig primordia are transplanted into the omentum, a membrane that envelopes the intestines and other digestive organs. When the primordia mature, they replace the missing rat insulin with pig insulin, retur...

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...oser to drugs that work by switching telomerase on permanently and keeping the immune cells young and strong in their fight against infection," said Effros. "These therapies are also easier to develop than gene-therapy drugs." The research was supported by a grant from the National Institute of Allergy and Infe...

Gene keeps neural cells on correct developmental path

...ed that adult neurons uniquely lack a protein that permanently turns off neuronal genes in the rest of the body's cells. Now, it turns out that precursor nerve cells contain that same repressive protein after all. In fact, the protein directs the complex network of genes that transforms an embryonic stem cell i...

Used in a new way, RNA interference permanently silences key breast cancer gene

...ed a way to use RNA interference (RNAi) so that it permanently hampers breast cancer development. The technique permanently silences activated STAT3, a crucial gene found in some human breast tumors, thus reducing the cancer...

Viral protein influences key cell-signaling pathway

...ke its cousin HIV, inserts its genetic information permanently into the DNA of a T lymphocyte and remains there for the life of the cell. HTLV-1 infection is also lifelong. A hallmark of HTLV-1 infection is the proliferation of T lymphocytes. This sets HTLV-1 apart from HIV, Lairmore says. "Unlike HIV, which ki...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...nce that even a one-time infection can potentially permanently change physiological systems, a phenomenon called "perinatal programming." Understanding how infection in newborns can disrupt memory in immune-challenged adults may help scientists to understand how exposure to germs or environmental stressors bef...

Bird Brains Show How Trial and Error May Contribute to Learning

Newly Discovered Compound Blocks Known Cancer-Causing Protein

...ng uncontrolled cell growth. Mutations in Ras that permanently activate it have been found in half of all colon cancer and 90 percent of pancreatic cancers, among other cancers. Casey and his colleagues in Duke's Department of Pharmacology and Cancer Biology have already discovered and developed another class o...

Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...tand that prenatal undernourishment makes a person permanently at higher risk for developing diabetes, so prenatal care is important," Dr. Patti said. "Moreover, if someone was born with low weight, they need to pay special attention to prevention tactics, including exercise and weight control to minimize insuli...
