  2024-11-18

  

  Steroidal CYP17 inhibitors can further be classified based on their mode of action, namely as mechanism-based inhibitors and type I and type II competitive inhibitors [129]. Recent studies investigated other biological targets than CYP17, and some new compounds have shown interesting dual activity a

  Conclusions and future direction ER(−)/PgR(+) breast cancers have a distinct clinical course, response to treatment, and molecular features when compared to other breast cancer types, however some of them are actually technical artifacts or consequences of too high definitions of positivity. Acco

  Implications for cancer ROS have a long history of being involved in the development and progression of cancer and increased ROS level is considered as a hallmark of many tumors [76], [77]. Initially, it was thought that ROS would serve as chemical mutagens that would indiscriminately damage cell

  Acknowledgments Protein microarrays were developed to provide miniaturized high-throughput tools to study protein function, ionophore and post-translational modifications. Just a few years ago, the seminal work performed in Stuart Schreiber's laboratory at Harvard University () and at Michael S

  The protein kinase CK2-mediated phosphorylation of HMGN1 was implicated to be involved in age-associated amnesia in rats [31]. It was shown that the decreased level of HMGN1 phosphorylation due to the down-regulation of CK2 activity could cause amnesia in aged rats, whereas the treatment with protei

  Vascular interventional radiology (VIR) laboratories perform a myriad of procedures ranging from simple tunneled peripherally inserted central catheter lines to complex transjugular intrahepatic portosystemic shunt placements. Infections are a common complication in the VIR environment; thus, the pr

  Aconitase clusters are prone to oxidations and are among the first to undergo a change in transition state during stages of electrophilic stress rendering them inactive [31]. Aconitase activity in LETO and OLETF did not differ at T0 suggesting that the early onset of insulin resistance may not be at

  The increased occurrence of ARIA-E in APOE ε4 carriers in phase 2 studies resulted in separate protocols for carriers and noncarriers in the subsequent phase 3 studies. Two 18-month trials comprising 1121 carriers and 1331 noncarriers with mild to moderate AD tested doses of bapineuzumab that varied

  Despite extensive studies on the expression of T. pallidum-induced pro-inflammatory cytokines, very little is known about T. pallidum-mediated intracellular signaling pathway activation, that leads to cytokine expression in macrophages. A network of signaling molecules, transcription factors, epigen

  Extracellular adenosine acts as a local modulator of cell function via four adenosine receptor subtypes (A1Rs A2AR, A2BR, and A3R) that are involved in numerous physiological and pathophysiological processes [31]. Each is encoded by a separate gene and has different functions, although with some ove

  Curcumin is the principal natural polyphenol curcuminoid of turmeric (Curcuma longa) rhizome, a member of the ginger family (Zingiberaceae) [13]. Curcumin has a wide spectrum of therapeutic properties, and it has been shown to possess antioxidant, anti-inflammatory, anticancer, antiangiogenesis, che

  Acl converts cytosolic citrate, CoA and ATP into acetyl-CoA, ADP+Pi and oxaloacetate (Fig. 1). This cytosolic enzyme is present in few Prokaryotes and in all Eukaryotes, but not in non-oleaginous yeasts [14]. Thus, this enzyme was presumed to be essential for FA synthesis [1], [13], [15]. In most mi

  ACL: A Metabolic Checkpoint for Sensing Excess Nutrients? During normal transitions between fasting and feeding, cells maintain energy homeostasis by integrating energy and nutrient status signals at key metabolic nodes, coordinating multiple processes. For example, the AMP-activated protein kina

  The first objective of the present study was to investigate the impact of ageing on arginase activity in tissues which exhibit age-related impairments in their function. The second objective was to determine whether l-arginine supplementation modulated the effect of ageing on arginase activity. The

  The physiologic conditions and signaling mechanisms that regulate apelin secretion and APLNR expression in malignant tissues appear to be multifactorial.
