  Coactivator Binding Sets APC/C Catalytic Core in Motion A coactivator not only recruits substrates to APC/C [18] (Figure 3B), but also stimulates repositioning of the catalytic core 19, 24. High-resolution cryo-EM maps of apo forms of APC/C without a coactivator show the catalytic core and platfo

  MTX and MTXPGs block the activity of the key enzyme DHFR (Fig. 1), which converts folates to their active forms – dihydrofolate (DHF) and tetrahydrofolate (THF). MTXPGs also potently inhibit thymidylate synthase (TS). Furthermore, during dTMP synthesis, TS utilizes the cofactor 5,10-methylene THF, w

  Conclusion Acknowledgments Introduction Arsenic (As) is one of the most toxic metals derived from the natural environment in soil, air and well water. It has two oxidative states: a trivalent form, arsenite, and a pentavalent form, arsenate. The inorganic As is more toxic than organic As. A

  Having generated synthetic cytokines and synthetic cytokine receptors, the logical next step has been to design fully synthetic cytokine/cytokine receptor systems, modifying either cytokine/cytokine receptor binding interfaces or cytokine-unrelated combinations of substances and their binding domain

  Regarding the mechanism of action of CRF, several studies have shown that low doses of CRF may preferentially activate CRF1 receptors in glutamatergic projection neurons, serotoninergic neurons or glutamatergic collaterals in the medial prefrontal cortex (Vertes, 2004). Indeed, prosencephalic inacti

  The idea of boron-based pro-estrogens has been utilized before; in previous studies, the selective estrogen receptor modulators (SERMs) tamoxifen and endoxifen have been masked as boronate esters.13, 14, 15 Tamoxifen and endoxifen both target ERα as therapies for breast cancer. The previous work foc

  It has previously been shown that human melanocytes are responsive to a multiplicity of hormonal triggers [10], particularly to pituitary or ovarian hormones [11]. Studies concerning the effects of Raltitrexed on human melanocytes led to inconsistent data [12], [13]. Im et al. [14] reported that the

  O-GlcNAc transferase OGT belongs to the metal-independent GT-B superfamily of glycosyltransferases, which has been well-reviewed previously [14,15]. OGT is an essential gene encoded on the X-chromosome, and it has two main regions: a long N-terminal tetratricopeptide repeat (TPR) region and a C-t

  ER stress was monitored by both an increase of the ER chaperone (GRP78, GRP94) and the activation of the ER resident caspase-12. ER stress response (also known as the unfolded protein response) is a defense mechanism against various cellular stresses which causes accumulation of unfolded proteins in

  Regulation of p53 via the ubiquitin-proteasome pathway Studies into regulation of p53 via PTM processes that involve phosphorylation, acetylation, ubiquitination, SUMOylation, neddylation, and methylation are being increasingly reported [23], [24]. Phosphorylation and acetylation of p53 stimulate

  Hedamycin, isolated from Streptomyces griseoruber, belongs to the highly cytotoxic pluramycin class of ER 50891 (Figure 3(c)). It consists of a planar anthrapyrantrione chromophore attached to two amino sugar rings at one end and a bisepoxide-containing side-chain at the other end (Figure 3(c)). Hed
