CRTC, not phosphorylated CREB1, drives cAMP-induced transcription across diverse cell types

Charles H. Adelmann, Xiaoqing Liu, Allison E. Greuel…·David E. Fisher

The paper shows that CRTC, not phosphorylated CREB1, drives cAMP-induced transcription across multiple cell types, challenging the canonical model of CREB1 activation.

Intermittent parathyroid hormone employs autonomous and non-autonomous mechanisms to drive osteogenesis from Ebf3-expressing skeletal progenitor cells

Byron Chan, Bingzi Dong, M. A. George…·Marc Nathan Wein

This study shows intermittent parathyroid hormone drives osteogenesis from Ebf3-expressing progenitors via both intrinsic and extrinsic mechanisms in mice and humans.

Regulation of intracellular cAMP levels in osteocytes by mechano-sensitive focal adhesion kinase via PDE8A

Garyfallia Papaioannou, Tadatoshi Sato, Caroline Houghton…·Marc Nathan Wein

This study identifies FAK's role in regulating cAMP levels in osteocytes through PDE8A, showing FAK inhibition increases cAMP and downstream signaling.
