A Porcine Dolly

...humans. Every cell in a pig's body carries some 50 copies of PERV. Even so, this does not necessarily mean the end of pig-organ transplantation. Indeed, PERV-infected mice remain as healthy as immunosuppressed animals can be. Needles to say that the jury is still out on using pigs as a granary for much need...

Drugs to stop burgeon of HIV

...ead. After working their way into cells and making copies of themselves, the virus goes to the surface membrane and wraps it around themselves before 'popping' off.// In 1996 the researchers showed that a protein created by HIV called Vpu formed ion channels in fatty membranes around cells. Ion channels ac...

Inherited gene important in ovarian cancer

...ious family history of cancer. We each inherit two copies of all genes - one from the father, one from the mother. It only takes one copy of BRCA1 to be lost for cancer protection to be reduced. It's possible for genes to be lost due to a malfunctioning when cells divide - this can happen even if you inheri...

Hidden influenza virus protein found

...irus. If it were junk, there should be only random copies of the peptide. If it were a protein, large quantities of the molecule should be present. Dr. Yewdell used a technique called immunofluorescence, which makes the molecule glow green, to show how much of it infected cells contained. “The cells we loo...

Pig cloning for organs

...he double knockout." The two genes are actually copies of the same gene, know as GATA1. "This is a major, major step in our attempt to be able to come up with an animal that can be used for transplantation," said Dr. Goran Klintmalm of the Baylor Institute of Transplantation Sciences. "They've knocked ou...

Cure for common cold

In clinical trials, Picovir shortened the length of the cold to roughly six days from seven. Patients took the pills three times a day for five days. First tr...

Y chromosome uses trick to repair its own genes

...led gene conversion. The chromosome carries backup copies of its important genes, and it can use one copy to fix a flaw in the other. The gene-fixing technique comes at a price. When the chromosome makes a mistake in the procedure, it can delete stretches of DNA. Such deletions, occuring in one in every c...

Gene Mutation Causes Ovarian Failure

...0 to 39. Investigators created mice that lack both copies of a gene called FOXO3a, which belongs to the forkhead gene family.// These genes are believed to control processes related to aging, cancer and diabetes. As the gene-altered mice aged, the females had fewer and smaller litters. By 15 weeks, which is...

Photographs An Effective Tool In Detecting Skin Cancer

Researchers then changed the appearance of the patients’ existing moles and created new moles on the photographs using cosmetic eyeliner pencils. Results of the study show patients who used the photographs were nearly 73 percent...
