Expanding the Paracrine Hypothesis of Stem Cell-Mediated Repair in the Heart: When the Unconventional Becomes Conventional.

Recent interest in mechanisms of stem cell-mediated repair in the heart have spawned the ``paracrine hypothesis'', which posits that stem cells release beneficial substances that improve regeneration and function of the injured and diseased …

Coordination of growth and endoplasmic reticulum stress signaling by regulator of calcineurin 1 (RCAN1), a novel ATF6-inducible gene.

Exposing cells to conditions that modulate growth can impair endoplasmic reticulum (ER) protein folding, leading to ER stress and activation of the transcription factor, ATF6. ATF6 binds to ER stress response elements in target genes, inducing …
