... on the molecular mechanism by which calcium-dependent gene expression regulates brain development and how ASD may occur if this process is compromised. Specifically, the studies of the calcium-dependent transcriptional repressor MeCP2 gave us much insight about how abnormal development may lead to ASD. Most...

...K.K. Pun; S.M. Tam Previous studies have shown that there are two types of parathyroid hormone (PTH) receptors on human dermal fibroblasts. We evaluate the effects of PTH on intracellular cyclic AMP, calcium and phosphoinositides in order to define the effector systems of the PTH receptors...
