2019-08-02
Thus, DGK-active sites remain ill-defined and, combined with the lack of crystal structures for mammalian DGKs, have limited our understanding of substrate and inhibitor binding. As a result, current DGK inhibitors consist of compounds with poor specificity within the DGK superfamily (de Chaffoy de

Recent studies have shown arsenic could cause autophagic cell death in malignant cells, including leukemia and malignant glioma SH-4-54 [16], [17]. However, at present, little is known about the consequences of arsenic-treated urothelial cells in autophagy and expression of its related proteins. Th

One of the most fundamental distinctions between Ub signals is substrate monoubiquitination versus polyubiquitination. With the exception of the E2, UBE2W, which represents a special case because it selective androgen receptor modulators only ubiquitinates the flexible N-termini of substrates [5], [

The pseudo DUBs KIAA0157 and Abraxas are required for the catalytic function of BRCC36. Comparison of the BRCC36–KIAA0157 heterodimer structure with an inactive BRCC36 homodimer structure provides a model for understanding how this functional interplay is achieved. As shown in schematic form in Figu

Homologous recombination (HR) has important roles in the repair of stalled or collapsed DNA replication forks, as well as of DNA double-strand breaks. Among the factors required for HR in human BI-D1870 are RAD51, BRCA1, and BRCA2 (Davies et al., 2001, Sung and Klein, 2006, Xia et al., 2001). BRCA1

The absence of the LIG3 gene in yeasts has prevented the use of genetically tractable lower eukaryotes, such as Saccharomyces cerevisiae and Schizosaccharomyces pombe, as models to gain insights into the cellular functions of and interplay between the DNA ligases encoded by the LIG1, LIG3 and LIG4 g

Stable isotope studies, applied to skeletal remains of early Pacific populations, have shown a trend toward a horticultural diet with temporal variation in response to local environmental conditions (Field et al., 2009; Kinaston and Buckley, 2013; Valentin et al., 2010, Valentin et al., 2014; Kinast

During the Lapita period in Tonga, the Talasiu site would have been an attractive location for human settlement as it overlooked an embayment holding large numbers of sessile and gregarious shellfish close to a fresh water solution channel, with gardening soils immediately inland. However, sea level

Neonatal hydronephrosis induced by TCDD
2019-08-01
Neonatal hydronephrosis induced by TCDD exposure via lactation has a critical window for onset: the incidence of this disease peaks around PNDs 1–4, followed by a rapid decrease to a substantially null level in adulthood (Couture-Haws et al., 1991; Yoshioka et al., 2016). The EP1 protein was localiz

CXCR5 is not only critical in the B cell lineage in FL. A high proportion of CXCR5-expressing follicular helper T cells (TFH) were observed in FL but not in closely related DLBCL [141] and further investigation revealed that FL regulatory T cells (Tregs) used a CXCL13-CXCR5 autocrine loop for positi

2019-08-01
The component E1 of PDHc (PDHc-E1) catalyzes the first step of multistep processes, using thiamine diphosphate (ThDP) and Mg2+ as cofactors.15, 16 Especially, this PDHc-E1 catalyzed process is a rate limiting step among multistep processes. Accordingly, the PDHc should be inactive by inhibiting the

Our finding that one enzyme acts both as a primase and a DNAP poses evolutionary and mechanistic questions. In particular, why do cellular organisms require two enzymes to fulfill de novo DNA synthesis? The inability of cellular replicases to perform as primases might be dictated by the challenges a
