Abstract
Signal transducers and activators of transcription 3 (STAT3) is known to participate in various cardiovascular signal transduction pathways, including those responsible for cardiac hypertrophy and cytoprotection. However, the role of STAT3 signaling in cardiomyocyte autophagy remains unclear. We tested the hypothesis that Angiotensin II (Ang II)-induced cardiomyocyte hypertrophy is effected, at least in part, through STAT3-mediated inhibition of cellular autophagy. In H9c2 cells, Ang II treatment resulted in STAT3 activation and cellular hypertrophy in a dose-dependent manner. Ang II enhanced autophagy, albeit without impacting AMPKα/mTOR signaling or cellular ADP/ATP ratio. Pharmacologic inhibition of STAT3 with WP1066 suppressed Ang II-induced myocyte hypertrophy and mRNA expression of hypertrophy-related genes ANP and β-MHC. These molecular events were recapitulated in cells with STAT3 knockdown. Genetic or pharmacologic inhibition of STAT3 significantly increased myocyte ADP/ATP ratio and enhanced autophagy through AMPKα/mTOR signaling. Pharmacologic activation and inhibition of AMPKα attenuated and exaggerated, respectively, the effects of Ang II on ANP and β-MHC gene expression, while concomitant inhibition of STAT3 accentuated the inhibition of hypertrophy. Together, these data indicate that novel nongenomic effects of STAT3 influence myocyte energy status and modulate AMPKα/mTOR signaling and autophagy to balance the transcriptional hypertrophic response to Ang II stimulation. These findings may have significant relevance for various cardiovascular pathological processes mediated by Ang II signaling.

Abstract
Derivation of induced pluripotent stem (iPS) cells requires the expression of defined transcription factors (among Oct3/4, Sox2, Klf4, c-Myc, Nanog, and Lin28) in the targeted cells. Lentiviral or standard retroviral gene transfer remains the most robust and commonly used approach. Low reprogramming frequency overall, and the higher efficiency of derivation utilizing integrating vectors compared to more recent nonviral approaches, suggests that gene activation or disruption via proviral integration sites (IS) may play a role in obtaining the pluripotent phenotype. We provide for the first time an extensive analysis of the lentiviral integration profile in human iPS cells. We identified a total of 78 independent IS in eight recently established iPS cell lines derived from either human fetal fibroblasts or newborn foreskin fibroblasts after lentiviral gene transfer of Oct4, Sox2, Nanog, and Lin28. The number of IS ranged from 5 to 15 IS per individual iPS clone, and 75 IS could be assigned to a unique chromosomal location. The different iPS clones had no IS in common. Expression analysis as well as extensive bioinformatic analysis did not reveal functional concordance of the lentiviral targeted genes between the different clones. Interestingly, in six of the eight iPS clones, some of the IS were found in pairs, integrated into the same chromosomal location within six base pairs of each other or in very close proximity. Our study supports recent reports that efficient reprogramming of human somatic cells is not dependent on insertional activation or deactivation of specific genes or gene classes.
