"DNA-Binding Proteins/metabolism"

Finding the missing link between the unfolded protein response and O-GlcNAcylation in the heart.

The ER stress-inducible transcription factor, x-box binding protein 1 (XBP1), which enhances protein glycosylation in the endoplasmic reticulum (ER), was shown to also enhance protein glycosylation outside the ER, via a process called …

p38 MAPK and NF-kappa B collaborate to induce interleukin-6 gene expression and release. Evidence for a cytoprotective autocrine signaling pathway in a cardiac myocyte model system.

In cardiac myocytes, the stimulation of p38 MAPK by the MAPKK, MKK6, activates the transcription factor, NF-kappaB, and protects cells from apoptosis. In the present study in primary neonatal rat cardiac myocytes, constitutively active MKK6, …

Collaborative roles for c-Jun N-terminal kinase, c-Jun, serum response factor, and Sp1 in calcium-regulated myocardial gene expression.

Electrical stimulation of contractions (pacing) of primary neonatal rat ventricular myocytes increases intracellular calcium and activates a hypertrophic growth program that includes expression of the cardiac-specific gene, atrial natriuretic factor …
