  2021-05-27

  

  The folate pathway plays an essential role in cell survival by generating 5, 10-methylene tetrahydrofolate as a one-carbon donor for the synthesis of deoxythymidine monophosphate (dTMP), purines, methionine and histidine. Disruption of this pathway leads to the critical deficiency of these key molec

  This review focuses on the atomic basis of CRM1-mediated nuclear export. There are now 27 crystal structures of CRM1 in the Protein Data Bank (PDB) (www.rcsb.org) [64]. Collectively, this large body of work explains various aspects of CRM1 function. Here we summarize the structure–function studies t

  Introduction Angiotensin II (Ang II) and Endothelin 1 (ET-1) are potent vasoconstrictive peptides recognized as key players in many cardiovascular diseases [1]. Cardiac hypertrophy, ischemic arrhythmia, and stroke have been associated to an overstimulation of the angiotensin II type 1 (AT1) recepto

  Estrogens: Definition and history The term “estrogens” refers to a group of female hormones, including estrone, estradiol, estriol, and estretrol (Fig. 1). Chemically, estrogens belong to the family of organic compounds known as steroids. As such, their core structure is composed of 17 carbon-carbo

  Interestingly, several ES cell lines are null for p53, possibly because the EWS-FLI1 chimeric protein can directly and indirectly interfere with p53 activity [38], [39]. The inhibition, loss and/or mutation of p53, one of the most common events in tumorigenesis, results in a decreased oxygen consump

  Here, two labs that helped characterize these two pathways have worked together to further test whether these apparently parallel pathways from β-AR to CaMKII-RyR might be related in series. Much of the work leading to the Epac pathway involved measurement of Ca sparks as an index of SR Ca leak, oft

  2021-05-26

  

  Regulation of cadherin switching The downregulation of E-cadherin during cadherin switching is induced by multiple mechanisms, including methylation of the E-cadherin promoter and signaling pathways that activate E-cadherin-suppressing transcription factors [[61], [62], [63]]. During the progress

  The methods for DNA MTase activity assay involve radioactive labelling [15], gel electrophoresis [16], high-performance liquid chromatography [17], [18], bisulfite conversion [19], [20], and affinity enrichment [21], [22]. In these methods, the methylated bases under the action of active MTase could

  — 1(2)-Dehydrogenation by a Δ1-KSTD is also a crucial step during Ramelteon synthesis degradation of the steroid core. Several Δ1-KSTDs were shown to be active under either aerobic or anaerobic conditions [27,29,47,50,66]. Furthermore, the last common intermediate of both aerobic and anaerobic ste

  In Agitoxin 2 to DDR1, the role of oligomerization and/or clustering of DDR2 in mediating its interactions with collagen is less understood. Current data show that in DDR2, like in DDR1, (i) dimerization [7] and higher-order oligomerization of its ECD [11], [22] enhance its binding to collagen, an

  Redundancy of tumor promoting signaling pathways is one of the mechanisms that prevent a lasting effect of targeted therapies, as has been demonstrated by the growing number of alternative pathways that confer resistance to EGFR-targeted therapies [3].
