Genetic Link to Adrenal Tumor Revealed

...rs. The researchers found four patients who had mutant copies of a gene that contains the information for Phosphodiesterase 11A (PDE11A). Phosphodiesterases are a family of enzymes involved in 'switching off' a cell's response to hormones, Dr. Stratakis explained. For a hormone to affect the cell, it ...

Three-Dimensional Image Of AIDS Virus – BY FSU Researcher

...nd organs. They imaged HIV samples as well as a mutant SIV (non-human primate) strain, genetically engineered for the study by collaborators at the National Cancer Institute to express about 74 spikes as opposed to the 14 found on the HIV virus –- more spikes make it easier to work with. The virus sample...

New Screening Techniques to Lead Advances In Pain Therapy

To understand the effect of a particular mutant protein, whose individual amino acid residue has been, mutated it has to be passed through the ion channel protein// and examine the effect that these mutations have on the channel's function. But it is a very laborious process. Hence the new high-t...

Researchers Discover Two Proteins Involved In Cellular Destruction Of HIV Virus

...lls with normal XPB and XPD than in those with the mutant proteins. "Overall, our results indicate that these two DNA repair proteins participate in the destruction of HIV cDNA in cells," Professor Fishel said. "This process reduces the pool of HIV cDNA that can integrate into host chromosomes, thereby prot...

Anticancer Properties of Vitamin D Revealed

...reported in the journal Molecular Cell, found that mutant forms of the protein that binds to vitamin D in the cell do not allow vitamin D to promote bone development and calcium transport but do permit it to regulate an oncogenic protein known as beta catenin. Some modified forms of vitamin D itself, which...

Anticancer Properties of Vitamin D Could Be Separated From Other Functions

...the journal Molecular Cell. It was found that that mutant forms of the protein that initiate binding with Vitamin D prevent it from exerting its effects on bone development and calcium transport, but do not hinder its anti-cancer property contained in a protein known as beta catenin. “We know beta catenin i...

Mutated Viruses Can Cure Tumors

...nd his team are now going beyond creating a simple mutant and "arming" viruses to make cancer cells commit suicide or to make the body's own immune system turn on them. This would seem the perfect biological weapon against cancer because viruses excel at killing cells, which is the goal of any cancer ther...
