  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

  To overcome problems with the biochemical reconstitution of these heterodimeric cytokines fusion strategies linking both subunits together have been proposed inspired by the “hyper-IL-6” [28]. Much like fusing a protein to a solubility enhancing protein such as MBP or SUMO, fusing two subunits of a

  Nucleophosmin (NPM1), which also plays a role on the nuclear export of ribosomal proteins and subunits (Maggi et al., 2008), is also a relevant MYC target, presumably through an interaction with CRM1. Conversely, it has been recently reported that specific SINE compounds reduce the levels of MYC in

  Results Discussion Drug resistance poses the greatest hurdle of achieving high efficacy with AADs in cancer patients. AAD-treated cancer patients often encounter intrinsic and evasive drug resistance that diminishes the therapeutic efficacy to only minor survival benefits in most cancer types.

  P4H is a nonheme iron(II) dioxygenase that uses O2 and α-ketoglutarate as co-substrates (Fig. 1A). The three-dimensional structure of mammalian P4H is unknown. We reasoned that an electrophilic analog of α-ketoglutarate could serve as an irreversible inhibitor of the enzyme and, hence, a useful prob

  Tacrine (9-amino-1,2,3,4-tetrahydroacridine) (I, Fig. 1) was the first AChEI to be approved by the Food and Drug Administration (FDA) for the treatment of AD [25], [26], [27], [28]. However, despite its good AChE inhibitory activity, tacrine was far from ideal due to its low bioavailability and shor

  The crystal structure of full-length CHK is still unsolved. However, the close homology between CHK and Csk suggests that these kinases share a similar structure. Therefore, the engagement of the CHK SH2–kinase linker with the αC-helix could control the activity of the CHK kinase domain. Sequence al

  In Murray–Darling rainbowfish, confirming the expected in vivo effects of androgenic progestins could be achieved using short-term exposures and determining expression profiles for androgen-responsive genes, or in longer term exposures by monitoring fecundity or the development of male secondary sex

  In brief, while previous studies have evaluated the individual roles of VDR and ER signaling pathways in breast cancer, in the present study we performed an in silico approach for comparative evaluation of these pathways. Considering the complex interaction networks in the context of cancer, such co

  Studies have shown that endothelial cells damaged by SAH can release a large amount of ET-1, thus its plasma level is elevated and is positively correlated with the symptoms of SAH (Lei et al., 2015, Masaoka et al., 1989). Our data obtained from SAH-along rabbits were consistent with these findings.
