We have reported earlier that a heat shock element in the first intron of human hsp90beta gene (iHSE) acts as an intronic enhancer to bind the heat shock factor (HSF1) and activates hsp90beta gene under heat shock. Here, we show that, in addition to the HSF1, Stat1 phosphorylation is indispensable in the event. We show that Jak2, a Janus kinase specifically(More)
Ribosome biogenesis is critical in the growth of eukaryotic cells, in which the synthesis of precursor ribosomal RNA is the first and rate-limiting step. Here, we show that human PIH1 domain-containing protein 1 (PIH1) interacts directly with histone H4 and recruits the Brg1-SWI/SNF complex via SNF5 to human rRNA genes. This process is likely involved in(More)
The SWI/SNF chromatin-remodeling complexes utilize energy from ATP hydrolysis to reposition nucleosomes and regulate the expression of human genes. Here, we studied the roles of human Brahma (hBrm) and Brahma-related gene 1 (Brg1), the ATPase subunits of the SWI/SNF complexes, in regulating human genes. Our results indicate that both hBrm and Brg1 interact(More)
Myogenin and its upstream regulator MyoD are known to be required for myogenic cell differentiation. Although both of them can be expressed in rhabdomyosarcoma-derived RD cells, the cells are unable to undergo full-scale terminal myogenic differentiation. 12-O-Tetradecanoylphorbol-13-acetate (TPA) has been found to be functional in the induction of RD cell(More)
OBJECTIVE To explore the effect of a non-lethal heat shock, in comparison with the treatment of interferon-gamma (IFN gamma), on the expression of major histocompatibility complex transactivator (CTA) and its downstream target gene of the human leukocyte antigens (HLA)-DR in Jurkat cells. METHODS The changes of CTA mRNA in Jurkat cells before and after(More)
Histone lysine (K) residues, which are modified by methyl- and acetyl-transferases, diversely regulate RNA synthesis. Unlike the ubiquitously activating effect of histone K acetylation, the effects of histone K methylation vary with the number of methyl groups added and with the position of these groups in the histone tails. Histone K demethylases (KDMs)(More)
Mammalian Sirtuin proteins (SIRTs) are homologs of yeast Sir2, and characterized as class III histone deacetylases of NAD(+) dependence. Unlike their lower counterparts that are directly involved in the extending of lifespan, mammalian SIRTs mainly function in metabolism and cellular homeostasis, among them, SIRT7 is the least understood. SIRT7 is localized(More)

CR6-interacting factor 1 (CRIF1) is ubiquitously expressed in human tissues. CRIF1 was first identified as a Gadd45γ (also known as CR6)-interacting protein, and it was also identified in a human colon cancer cell line stably transformed with p53. These results suggested that CRIF1 functions in the nucleus with p53 and Gadd45 family proteins in the(More)
