To Patent or Not-A Question of Life

...risis. Novartis is backing its right to patent a modified version of its drug Glivec produced in India, used to treat leukemia. If it wins its case this will mean the cost of the drug shooting to almost ten times its present value and a move towards more stringent rules on drug patenting. This in turn wil...

Suppression of Enzyme Delays a Type of Breast Cancer

...onducted on laboratory mice which were genetically modified to develop into a breast cancer condition of humans. This research headed by Michel L.Tremblay along with Sophie Julien of McGill cancer Center, Quebec delayed the advancement of a particular kind of breast cancer linked to ERBB2 gene. In this case...

Immune System Gears Up by Specific Enzymes

...r studies using animal cells that were genetically modified to carry LAG-3 on their surface; the researchers also used drugs that inhibit enzymes that chop off LAG-3. The team demonstrated that the two enzymes that cleave LAG-3 are controlled by of distinct but overlapping signals generated from the T cell re...

The gene for the specific protein is injected into the hen's DNA, specifically into that part that controls the production of egg white. Some of these genetically- engineere...

A Spoonful Of Sugar to 'Switch' the Bacteria on and Off

...ill provide that control." Professor Carding has modified one of the trillions of bacteria in the human gut so that it will produce human growth factors which help repair the layer of cells lining the colon, so reducing inflammation caused by IBD. But he's also adapted the bacteria so it only activates in t...

‘Sweet Revenge’ on Inflammatory Bowel Diseae

... On encountering the added source of xylan, the modified bacteria produce cytokines, which heal the gut. A patient can control the amount of cytokines being produced by controlling how much xylan they eat; when the xylan runs out cytokine production stops. Carding believes this discovery could even le...
