  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

  Introduction Natural killer (NK) cells have an unique ability to directly lyse transformed, virus-infected or stressed cells without prior sensitization or major histocompatibility complex (MHC) class I restriction [1], [2]. They were initially defined and shown to be important effectors of the i

  Another layer of CK1 regulation in the Hh and Wnt pathways is to employ different CK1 isoforms to phosphorylate distinct pathway components or even distinct sites on the same substrates. In this regard, it has been shown recently that the membrane-associated CK1 isoform CK1γ, but not the cytosolic i

  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

  Structure and function of EPAC isoforms EPACs are guanine nucleotide exchange factors (GEFs) for the Ras-like GTPases Rap1 and Rap2 [9]. There are two mammalian EPAC isoforms, EPAC1 and EPAC2 1, 2 (Figure 1). Whereas EPAC1 displays a wide tissue distribution, the expression of EPAC2 is more rest

  According to the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB, 1992), peptidases are divided into two classes, namely exopeptidases and endopeptidases, based on their actions on substrates and their active sites, respectively. Endopeptidases inclu

  Common enzyme quantitative methods include enzyme-linked immunosorbent assay [,] (ELISA), chemiluminescence (CLIA) [, , ] and immunochromatography []. The advantages of ELISA are cost reduction and automation, but non-specific reaction caused by HOOK effect, false positive caused by cross-contaminat

  The excitatory amino transporters L-glutamate or glutamate mediates most of the excitatory neurotransmission within the mammalian central nervous system (CNS) and has been implicated in numerous peripheral nervous system (PNS) pathways. The excitatory amino acids, including glutamate, are of great

  The CYP3A genes are regulated physiologically by glucocorticosteroids, growth hormone, thyroid hormones and cytokines [13, 20, 30]. It has been shown that glucocorticoid receptor (GR), pregnane X receptor (PXR), constitutive androstane receptor (CAR) and vitamin D receptor (VDR) play an important ro

  Several evidences showed that seizures increase brain extracellular glutamate, which binds to N-methyl-d-aspartate (NMDA) receptor, then up-regulated cyclooxygenase-2 (COX-2) expression in brain capillaries to increase BBB P-gp expression [11,13,29,30]. A recent study demonstrated a different signal

  As described above, we designed and synthesized a new 1,4-di-substituted isoquinoline lead compound, and was identified as a ligand with moderate potency for the CRTH2 receptor. We initially we examined the effects of the steric factor of R group on the CRTH2 binding potency (). When the methyl gro

  Our structures also provide new insights into CRTH2 drug development. The ligand binding pocket revealed by our structures comprises many aromatic residues and a few polar residues at the distal end. Correspondingly, most CRTH2 antagonists share a similar structural feature characterized by an aceta

  It is important to note that CRF1 may be activated during acute stress and early phases of anxiety disorders (Coric et al., 2010, Ising et al., 2007), as well the administration of Astressin 2B into the lateral septum did not have an effect on anxiety-like behavior in low-stress conditions but had a
