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

...ch 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 relentless prodding by MYC to keep multiplying. ...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...contrast, the team did not find in yeast a network they found in both worm and fly that is involved in the guidance of nerve cell axons to their synaptic targets, or junctions, with other nerve cells. The process, considered an initial step in the development of the central nervous system, would not be ne...
