We aimed to determine gene expression patterns in the anterior pituitary (AP) of heifers before and after ovulation via deep sequencing of the transcriptome (RNA-seq) to identify new genes and clarify important pathways. Heifers were slaughtered on the estrus day (pre-ovulation; n=5) or 3 days after ovulation (post-ovulation; n=5) for AP collection. We randomly selected 4 pre-ovulation and 4 po...

Using simple stellar population synthesis, we model the bulge stellar contribution in the optical spectrum of a narrow-line Seyfert 1 galaxy RE J1034+396. We find that its bulge stellar velocity dispersion is 67.7± 8 km s . The supermassive black hole (SMBH) mass is about (1−4)×106M⊙ if it follows the well-known MBH−σ∗ relation found in quiescent galaxies. We also derive the SMBH mass from the ...

BACKGROUND/AIMS Stromal interacting molecule-1 (STIM1) aggregation and redistribution to plasma membrane to interact with Orai1 constitute the core mechanism of store-operated Ca2+ entry (SOCE). Previous study has revealed that calsequestrin-1 (CSQ1) regulates SOCE in HEK293 cells through interacting with STIM1 and inhibiting STIM1/Orai1 interaction. Here, we further investigate how CSQ1/STIM1 ...

The yeast Spt10p activator is a putative histone acetyltransferase (HAT) possessing a sequence-specific DNA-binding domain (DBD) which binds to the upstream activation sequences (UAS elements) in the histone gene promoters. Spt10p binds to a pair of histone UAS elements with extreme positive cooperativity. The molecular basis of this cooperativity was addressed. Spt10p (640 residues) is an elon...

Rapid desensitization of G protein-coupled receptors is mediated, at least in part, by their phosphorylation by the G protein-coupled receptor kinases (GRKs). However, only in the case of rhodopsin have the actual sites of receptor phosphorylation been unambiguously determined. Although previous studies have implicated the cytoplasmic tail of the b2-adrenergic receptor (b2AR) as the site of GRK...
