Controlling Neuronal Activity

American Journal of Psychiatry, 2008
With a new technology called optogenetics, it is possible to turn neuronal activity on and off in distinct neuronal populations, using cell-type specific, optically-sensitive, molecular, neuronal activity "switches." These "switches" are microbial, light-sensitive ion conductance-regulating proteins, exemplified by channelrhodopsin-2 (ChR2) and ...

Mechanisms controlling CDK9 activity

Frontiers in Bioscience, 2006
This review primarily focuses on the mechanisms that modulate CDK9 activity and its recruitment to cellular genes, where it phosphorylates the C-terminal domain of RNA polymerase II (RNAPII) as well as negative elongation factors. CDK9 associates with each of four cyclins (T1, T2a, T2b and K), forming distinct positive transcription elongation factors (

Electromagnetically controllable osteoclast activity

Bone, 2014
The time-varying electromagnetic field (EMF) has been widely studied as one of the exogenous stimulation methods for improving bone healing. Our previous study showed that osteogenic differentiation of adipose-derived stem cells was accelerated by a 45-Hz EMF, whereas a 7.5-Hz EMF inhibited osteogenic marker expression.
