Histone deacetylase inhibitors induce in human hepatoma HepG2 cells acetylation of p53 and histones in correlation with apoptotic effects

2007

This report shows that histone deacetylase inhibitors (HDACIs) induced apoptosis in human hepatoma HepG2 cells in a dose- and time-dependent manner. Trichostatin A (TSA), ITF2357 and suberoylanilide hydroxamic acid (SAHA), which were very effective agents, caused apoptotic effects after a lag phase of 12-16 h. In order to elucidate the mechanism of HDACIs action in HepG2 cells we have studied the effects of TSA, ITF2357 and SAHA on acetylation of p53 and histones H2A, H2B, H3 and H4. It was observed that HDACIs rapidly induced acetylation of these proteins, being the effects clearly visible already at 30 min of treatment at the same doses which caused apoptosis. Analysis of the immunocomple…

COINVOLGIMENTO DELLO STRESS DEL RETICOLO E DEL PROCESSO AUTOFAGICO NELL’APOPTOSI INDOTTA DAL CANNABINOIDE SINTETICO WIN IN CELLULE DI EPATOMA UMANO I…

2009

Studi da noi condotti precedentemente hanno dimostrato la capacità del cannabinoide sintetico WIN di indurre apoptosi in cellule di epatocarcinoma umano HepG2 attraverso un meccanismo, dipendente dal fattore trascrizionale PPARg, che prevede riduzione dei livelli di alcuni fattori di sopravvivenza e attivazione di fattori pro-apoptotici della famiglia Bcl-2 (M. Giuliano et al. Biochimie. 2009). Recentemente è, inoltre, emerso che in cellule di glioma i cannabinoidi possono stimolare l’apoptosi attraverso induzione di stress del reticolo endoplasmatico seguito da autofagia. Scopo L'obiettivo del presente studio è stato quello di valutare il coinvolgimento dell’autofagia nel percorso di morte…
