Rationale: Pathological cardiac myocyte hypertrophy is thought to be induced by the persistent increases in intracellular Ca needed to maintain cardiac function when systolic wall stress is increased. Hypertrophic Ca binds to calmodulin (CaM) and activates the phosphatase calcineurin (Cn) and CaM kinase (CaMK)II. Cn dephosphorylates cytoplasmic NFAT (nuclear factor of activated T cells), induci...
Purpose: Wnt pathways control key biological processes that potentially impact on tumor progression and patient survival. We aimed to evaluate DNA methylation at promoter CpG islands (CGI) of Wnt pathway genes in ovarian tumors at presentation and identify biomarkers of patient progression-free survival (PFS). Experimental Design: Epithelial ovarian tumors (screening study n 1⁄4 120, validation...
Mitochondria can sense signals linked to changes in energy demand to affect nuclear gene expression. This retrograde signaling pathway is presumed to be involved in the regulation of myoblast proliferation and differentiation. We have investigated the regulation of mitochondrial biogenesis and production of putative retrograde signaling agents [hydrogen peroxide (H(2)O(2)) and Ca(2+)] during th...
The phenotype of NFATc2(-/-) c3(-/-) (double knockout [DKO]) mice implies a disturbed regulation of T cell responses, evidenced by massive lymphadenopathy, splenomegaly, and autoaggressive phenomena. The population of CD4(+) CD25(+) T cells from DKO mice lacks regulatory capacity, except a small subpopulation that highly expresses glucocorticoid-induced tumor necrosis factor receptor family-rel...
Jahnke VE, Sabido O, Freyssenet D. Control of mitochondrial biogenesis, ROS level, and cytosolic Ca concentration during the cell cycle and the onset of differentiation in L6E9 myoblasts. Am J Physiol Cell Physiol 296: C1185–C1194, 2009. First published March 18, 2009; doi:10.1152/ajpcell.00377.2008.—Mitochondria can sense signals linked to changes in energy demand to affect nuclear gene expres...
AIMS Alternative transcription and splicing of the allograft inflammatory factor-1 (AIF-1) gene results in the expression of two different proteins: AIF-1 and interferon responsive transcript-1 (IRT-1). Here, we explore the impact of AIF-1 and IRT-1 on vascular smooth muscle cell (VSMC) activation and neointima formation, the mechanisms underlying their alternative splicing, and associations o...
RATIONALE Pathological cardiac myocyte hypertrophy is thought to be induced by the persistent increases in intracellular Ca(2+) needed to maintain cardiac function when systolic wall stress is increased. Hypertrophic Ca(2+) binds to calmodulin (CaM) and activates the phosphatase calcineurin (Cn) and CaM kinase (CaMK)II. Cn dephosphorylates cytoplasmic NFAT (nuclear factor of activated T cells),...
