...ble Factor (HIF) responds to low oxygen levels and switches on the genes. However, the nuts and bolts of how it does that have to date only been partially understood.HIF was identified as having two segments that were involved in the switching process.

...addition, one of the teams has identified how MEF2 switches from one program to the other, that is, from dendrite-promoting to dendrite-pruning, and the researchers have identified some of MEF2's targets. In the words of Azad Bonni, MD, PhD, HMS Associate Professor of Pathology, "Changes in the morphology ...

Two in One Cell Offers Hope to Find a Cure for Cancer

...ll. After the cell encounters a pathogen, the cell switches roles from killer to dendritic like messenger. The cell sprouts long, hairy tentacles called dendrites. It uses its "arms" to increase the amount of surface area it reaches to communicate and interact with other immune cells. Then, the cell dies and ...

Gene That Causes Dry Skin, Identified

... that about 10% of Europeans carry a mutation that switches off the filaggrin gene, causing a very common dry, scaly skin condition known as ichthyosis vulgaris. Statistics show that about five million people in the UK have a milder form of the condition, while 120,000 people in the UK have no filaggrin pr...

Mouse Models To Determine The Cause Of Aggressive Leukemia

...hen a fragment of the Bcr gene from one chromosome switches over to fuse with a portion of the Abl gene from the other chromosome. Bcr-Abl encodes for an enzyme called a tyrosine Kinase. This causes the abnormal, uncontrolled multiplication of leukemic cells. It was also shown that by inhibiting the Bcr-Abl k...

Understanding how humans detect sweet taste

...t. Then the researcher found that taste perception switches back to sweetness when these high concentrations are rinsed from the mouth with water, resulting in the aftertaste experience known as sweet water taste. This has guided the researchers to an increased understanding of how humans detect sweet taste...

Sensory Input Necessary During "Critical Periods" Of Brain Development

...ne replacement. "We need to try to find the major switches that turn on genes in the downstream network as opposed to looking at each element of the network and designing therapy based on each gene," said Shatz. This study helps explain why it is that children learn so quickly and easily, and it lends crede...

Scientists Uncover The Secret Behind The Speed In Nerve cells Conduction

...cells use a complex system of proteins as sensors, switches and activators to scan the outside world and decide when to open membrane doorways to take in food, expel waste and export chemical products to the rest of the body. Many studies suggest that a group of proteins called SNAREs act like the cell's lo...
