Recently, several Pt(IV) complexes as prodrugs have been designed and studied to enhance anti-tumor efficacy of traditional Pt(II) drugs, improving their cellular uptake and blood-circulation time [26], [27], [28], [29]. Compared with their Pt(II) counterparts, six-coordinated Pt(IV) complexes with

Other s6 kinase outside of the circadian clock also have effects on CR. Lithium, a drug used to treat bipolar disorder, has been shown to lengthen τ in a variety of systems [17]. While the molecular mechanism whereby lithium exerts its therapeutic effect is unclear, it is known to be an inhibitor o

Effects of estrogen on vascular function Atherosclerosis is a chronic inflammatory condition of the vascular wall (Figure 1) that can be converted to an acute clinical event by the induction of plaque rupture or erosion, leading to thrombosis [58]. This perpetuating process is characterized by ph

SS is a high-grade malignant soft tissue sarcoma accounting for 5%–10% of soft tissue sarcomas. After RMS, SS is the most common sarcoma in children, adolescents and young adults [9]. SS originates primarily in the lower (62%) and upper (21%) extremities but may occur at any anatomic site [9], [10].

Introduction CYP450 is a superfamily of heme-containing monooxygenases, many of which are expressed in the liver, and they are significant phase-I (S)-Methylisothiourea sulfate synthesis in drug metabolism and detoxification. There are three subfamilies (CYP1, CYP2 and CYP3) that are mainly involve

How does an increase in E2 affinity for the RING domain favor higher activity and polyubiquitination by the E2? Binding of the RING domain to the E2 positions the donor Ub in the E2~Ub conjugate in a closed complex [16], [17], [18] that increases the reactivity of the thioester [60]. A higher affini

2020-12-12

The ubiquitin–proteasome system (Ub–P) is the main cellular machinery for protein turnover in eukaryotic cells (Glickman and Ciechanover, 2002). Degradation by Ub–P involves two steps. Target proteins are selectively, specifically, and covalently attached to ubiquitin (Ub) chains, followed by Ub-tag

The modification of proteins with the small 76-amino UCB 35625 protein ubiquitin (Ub) plays a central role in many key cellular processes. Ubiquitylation of a target protein requires the concerted action of a cascade of three enzymes (Figure 1). The ubiquitin-activating enzyme (E1) catalyzes the for

As mentioned above, there are two major pathways for the DSB repair in mammalian cells, NHEJ and HR/HDR (homology-directed repair) [13], [51]. NHEJ is active throughout the cell cycle, predominately during the G0 and G1 phases and is considered the major pathway for the DSB repair in human cells [52

Here we uncover a highly diverse superfamily of self-replicating MGEs, dubbed pipolins, which are present in three major bacterial phyla, as well as in mitochondria, and encode divergent PolB carrying TPR1 and TPR2 subdomains. Biochemical characterization of a representative enzyme encoded by a pipo

In contrast to the methylation that is catalyzed exclusively by DNMTs, there have been suggested several pathways that could induce demethylation (Watt & Molloy, 1988). However, the existence and influencing of enzymes that promote active demethylation remains elusive. Studies aiming to gain more in

Considering the divergence of multiple DGAT isoforms, we examined whether MiDGAT1 and MiDGAT2s utilized different fatty acids as the substrate to synthesize TAGs. GC-MS analysis indicated that C16:0 and C18:0 were the major components of TAGs in yeast cells, and all three MiDGATs displayed the same

The IL-10 family consists of nine related molecules: IL-10, IL-19, IL-20, IL-22, IL-24, IL-26, IL-28α, IL-28β, and IL-29 [34]. These molecules have a somewhat conserved primary structure and contain a core of hydrophobic Z-YVAD-FMK and two pairs of disulfide bonds in the chain, giving them a simila
