Skimmed milk -- Straight from the cow

...d fats. Experts say that the discovery of these rogue milkers could completely revolutionise the dairy i...e how much milk the cows actually produce. The rogue cows were discovered when biotech company ViaLactia screened the range of milk compositions across t...

It's never too late to get it back! Aging interrupted

...ause it normally kills some cells like damaged and rogue cancer cells to provide energy when it is starving. Then it replaces these cells when a meal is eaten. It seems it is the total number of calories which are consumed, rather than the type of food which is the key to the effects of low calorie di...

Hope for a more effective and less toxic cancer drug

...ncontrollably. This uncontrolled multiplication of rogue cells can lead to cancer. Conventional chemothe...cking cancer. Rather than attempting to poison the rogue cells, the new drug attempts to reactivate the healthy and normal cell death program that failed to ...

What animals can tell us about hemorrhage, organ transplants and aging

...that oxidative stress -- damage caused to cells by rogue oxygen atoms known as reactive oxygen species -- shortens lifespan. Animals that could best prevent reactive oxygen species (ROS) generation, neutralize them, or repair the damage it causes, would live the longest, the theory goes. Buffenstein's rese...

Research links protein to breast-cancer migration

...d to kick start the anoikis process and kill these rogue cells. But the cancer cells are clever and learn how to avoid being destroyed, which means these treatments no longer work and patients often see their breast cancer return. Dr. Gilmore said: "Understanding more about how the body's natural defences...

Faults in newly discovered breast stem cells may lead to tumours

...ide clues about how breast cancer develops and how rogue cells evade current therapies. Under normal circ... the exact makeup of genes expressed by normal and rogue stem cells will need to be determined. Then a drug will be designed to engage with and neutralize th...

Scientists directly view immune cells interacting to avert autoimmunity

..., or Treg, cells control the destructive action of rogue autoimmune cells when each of the two cell types interact with a third kind of cell. The role of the third cell type -- the antigen-presenting dendritic cell -- in preventing autoimmune attacks of healthy tissue has been a focus of intense research ...

Software 'agents' could help unmask reality of disease clusters

...and prevent 'Trojan horse'-like attacks by fake or rogue agents. "These mechanisms could include the creation of virtual institutions to insulate host organisations from agents and minimise leakage by limiting access to only the necessary data." ...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...zealous cells to undergo apoptosis. However, such rogue cells can still become fully cancerous if they succeed in eliminating p53 activity, in effect silencing the command to commit suicide. This situation occurs when increased TEL2 activity reduces the cell's ability to trigger apoptosis in response to r...
