Clues to Allay Aging

...as stunted growth after a couple of weeks. All the transgenic mice died when they were four weeks old. The XPF gene is not the only gene that plays a role in aging or in progeria. However it does play a significant role in repairing damage that occurs in DNA regularly. Experts opine that the hidden reasons b...

Despite the report's emphasis on...

How Taste-buds Develop?

...ling are easily visualized in specially engineered transgenic mice, using an enzymatic assay. "We noticed in the tongue that there was this beautiful pattern of blue spots that correspond to the developing taste papillae," says Millar. "This connected the Wnt pathway to their development." In the present stud...

Non-Steroidal Anti-Inflammatory Drugs Can Cause Liver Damages

...Rudnick says. "The effect of indomethacin on these transgenic mice suggests that NSAIDs may be an example of such an environmental influence." Source-Eurekalert SRI...

Swelling of Prostate Gland Prevented with New drug

.... On testing an estrogen receptor-beta agonist on transgenic mice with BPH Risbridger and her team found that the drug activated just one of the two cell receptors for the hormone to produce the positive impact. This was presented at the Society for Endocrinology conference. The scientists found that regulati...

Mouse Model Demonstrates Immune System Reaction In Chlamydia Infection

...a protein. These mice are known as T cell receptor transgenic (TCRtg) mice and have none of the T cell diversity found in a normal mouse. Starnbach and his team harvested T cells from the Chlamydia-specific TCRtg mice, labeled them with a dye, and injected them into normal mice. By boosting the number of Chlamy...

Researchers have Identified the Gene that Spreads Skin Cancer

...its nearly impossible. Chin had previously created transgenic mice in which melanoma could be induced by turning cancer genes on or off. When tumors from these mice were transplanted into normal mice lacking an immune system, the cancers grew and a few of them became metastatic. Genome scans of the metastatic t...

Prostate cancer risk pronounced with selenium-protein deficiency

...Sciences on research findings using specially bred transgenic mice that suggest it is the level of selenium-containing proteins in the body that is instrumental in preventing cancer, and that dietary selenium plays a role in stimulating the body's level of these selenoproteins. Two genetically manipulated mic...

Protein Responsible for Memory Loss in Alzheimer's disease

...ts found a form of the amyloid beta protein in the transgenic mice that displayed early signs of memory loss but which had no plaques or nerve cell loss. They isolate and purified this protein complex and injected it into a healthy mouse and saw that there was a decline in their cognitive ability. Hence furth...

Non-Coding RNA Vital For Gene Activation And Protein Expression

...Ubx gene. The function of cells can be modified by transgenic transcription of non-coding TRE RNA. Non-coding RNAs have been regarded to be inert, having a limited role in inducing expression or activation of genes followed by protein expression. The present research has highlighted that non-coding RNAs can h...
