αCP Poly(C) binding proteins act as global regulators of alternative polyadenylation.

We have previously demonstrated that the KH-domain protein αCP binds to a 3' untranslated region (3'UTR) C-rich motif of the nascent human alpha-globin (hα-globin) transcript and enhances the efficiency of 3' processing. Here we assess the genome-wide impact of αCP RNA-protein (RNP) complexes on 3' processing with a specific focus on its role in alternative polyadenylation (APA) site utilization. The major isoforms of αCP were acutely depleted from a human hematopoietic cell line, and the impact on mRNA representation and poly(A) site utilization was determined by direct RNA sequencing (DRS).

Outcomes of angiosome and non-angiosome targeted revascularization in critical lower limb ischemia.

Objective: Blood supply to the foot is from the posterior tibial, anterior tibial, and the peroneal arteries. Ischemic ulceration of the foot is the most common cause for major amputations in vascular surgical patients. It can be presumed that revascularization of the artery directly supplying the ischemic angiosome may be superior to indirect revascularization of the concerned ischemic angiosome.

Too much PABP, too little translation.

Posttranscriptional regulation is of critical importance during mammalian spermiogenesis. A set of mRNAs that encode proteins critical to normal sperm formation are synthesized early in the process of male germ cell differentiation and are stored in a repressed state. These mRNAs are subsequently translationally activated during the process of spermatid elongation and maturation.

Liver X receptor inhibits the synthesis and secretion of apolipoprotein A1 by human liver-derived cells.

The liver X receptor (LXR) agonist TO901317 inhibited the synthesis of apolipoprotein A1 (apo A1) by human liver-derived cells, including the formation of lipid-poor, prebeta-migrating high-density lipoprotein (HDL). Despite activation of the lipid transporter ABCA1 under these conditions, cellular efflux of PL and cholesterol from liver cells was also reduced. By assaying transcription from full-length and truncated promoters and by site-directed mutagenesis, the effect of LXR and its ligand was localized to a binding site for hepatic nuclear factor-4 (HNF4) in the proximal apo A1 promoter (-132/-119 bp).

Unique classes of mutations in the Saccharomyces cerevisiae G-protein translation elongation factor 1A suppress the requirement for guanine nucleotide exchange.

G-proteins play critical roles in many cellular processes and are regulated by accessory proteins that modulate the nucleotide-bound state. Such proteins, including eukaryotic translation elongation factor 1A (eEF1A), are frequently reactivated by guanine nucleotide exchange factors (GEFs). In the yeast Saccharomyces cerevisiae, only the catalytic subunit of the GEF complex, eEF1Balpha, is essential for viability.

Repression of c-kit and its downstream substrates by GATA-1 inhibits cell proliferation during erythroid maturation.

Stem cell factor (SCF), erythropoietin (Epo), and GATA-1 play an essential role(s) in erythroid development. We examined how these proteins interact functionally in G1E cells, a GATA-1(-) erythroblast line that proliferates in an SCF-dependent fashion and, upon restoration of GATA-1 function, undergoes GATA-1 proliferation arrest and Epo-dependent terminal maturation. We show that SCF-induced cell cycle progression is mediated via activation of the Src kinase/c-Myc pathway.

Activation of ATP-binding cassette transporter A1 transcription by chromatin remodeling complex.

Objective: Liver X receptor (LXR) regulates the transcription of ATP-binding cassette transporter A1 (ABCA1) by binding to the DR-4 promoter element as a heterodimer with retinoid X receptor (RXR). The role of chromatin remodeling complex in LXR or ABCA1 activation has not been established previously. In this study, we investigated the activation of ABCA1 by brahma-related gene 1 (BRG-1) and brahma, members of the SWI/SNF (mating type switching/sucrose nonfermenting) chromatin remodeling complex.
