Reason for diabetes drug causing edema discovered

...ucose levels. The research results showed that in mice the drug caused bloating with increase in body weights. This shows that there is fluid retention in the body that is causing edema. The receptor affects the distal nephron, which plays an important role in deciding the sodium metabolism in the body. ...

Language development linked to Foxp2 gene

... In the research where scientists have engineered mice with Foxp2 gene mutations, results demonstrate that infant mice with the mutations emitted disrupted ultrasonic vocalizations when separated from their mothers. The...

Understanding Chronic Infections May Help in Developing Therapeutic Vaccines

...d was that the T cells in the chronically infected mice responded poorly to the vaccine." Specifically, Wherry says, the T cells failed to proliferate, or expand in number. This failure to proliferate seemed to correlate with a high viral load, which suggests several directions researchers might pursue ...

Researchers reversed the process of memory loss

...sity of Minnesota had manipulated the genes of the mice so that the mice have a clinical condition very similar to the Alzheimer’s’ disease in humans. Then the researchers u...

Environmental estrogens can cause breast cancer

...hemical industries. The study was carried out in mice experiments by inducing the chemical 4-nonylphenol into mice and all the 5 mice induced with 4-nonylphenol developed tumors in the breast. The study shows that ...

New clues to maternal aggressive behavior

...phological plasticity. Drawing parallel from the mice study, the researchers from University of Edinburgh said that in highly anxiety prone animals, the release of the hormone directly influences the level of maternal offensive behavior against a perceived threat. This is more pronounced in lactating mo...

Scientist discover secrets of ageing

...archers who had worked with genetically engineered mice that ages faster, have said that the symptoms of aging is more emphatic in some critical cells that are adult stem cells and hence are required for replacing the dying cells. This may lead to impairment of the regeneration process of the bone marrow,...

Treatment for heart damage in muscular dystrophy may be possible

MicroRNA provides new insight into birth defects

... Genetics Institute have used genetically modified mice to see how the microRNAs are responsible for the physiological growth of animals. When the mice were grown without the microRNA molecules they grew to be malformed and with nonfunctional limbs. M...

Knowledge Of Infertility Gets New Inputs

...rease fertility in them Drawing parallel from the mice study they have done, researchers had said that this is the first time the role of the receptor gene had been unveiled. The researchers have also been able to design a simple blood test that will be able to say if the women are lacking in this gene o...

New Insight To The Role Of Peptide Signals

.... In their experiments with genetically controlled mice they had showed that the effects of the endogenous alpha-MSH are quite evident in the sexual behaviors of the mice. The researchers also conclude that there is a system in which the alpha-MSH generating neurons play an important part in controlling t...

New Discovery May Help Treat Infertility

...fertility drugs did not improve ovulation rates in mice that were genetically engineered to lack estrogen receptor beta. The estrogen receptor beta is one of two estrogen receptor proteins which mediate the effects of estrogen hormones and are present throughout the female reproductive tissues. The new da...
