  2021-06-07

  

  The Wnt signaling pathway has been demonstrated to be responsible for a variety of biological processes. The three best-characterized Wnt signaling pathways are the canonical Wnt pathway, the noncanonical planar cell polarity pathway, and the noncanonical Wnt/calcium pathway. The canonical Wnt/β-cat

  Other factors regulating DNA-PKcs Recent work in the field has also focused on factors that regulate NHEJ and NHEJ factors, in particular proteins that modulate DNA-PKcs. In this section we will highlight a number of factors which have been found to regulate DNA-PKcs. DNA-PKcs phosphorylation at

  2021-06-07

  

  Over the past decade, targeting DNA repair proteins has emerged as an effective tool to enhance chemosensitivity of malignant cells [9]. However, identification and selection of the proper target of DNA repair pathways is critical to increase cytotoxic activity of chemotherapeutic agents in cancer c

  2021-06-07

  

  Introduction Coping with DNA damage is possible thanks to surveillance mechanisms (checkpoints), that detect the problem and promote its solution [1], [2], and to repair and tolerance pathways that remove the lesions or reduce the damage consequences [3], [4]. Failures in these processes have a h

  2021-06-07

  

  Mitochondrial depolarization induced by DHODH inhibition (Figure 5A) may also contribute to the selective effects of DHODH inhibitors on KRAS mutant cells. If so, the effect may arise more from pro-apoptotic effects of mitochondrial depolarization (Lemasters et al., 1998) than from impaired oxidativ

  2021-06-07

  

  In this context, we initiated a program to develop new antiviral chemotypes towards a host factor implicated in mao inhibitor replication: the host (human) dihydrofolate reductase (DHFR) [21]. We recently identified this enzyme as the molecular target of 1-aryl-4,6-diamino-1,2-dihydrotriazines, str

  2021-06-07

  

  Two in vitro reports using lung fibroblasts have shown that cell transmigration, using transwell migration experiments, through collagen I-coated inserts is mediated by DDR2 and the DDR2-associated signaling kinases JAK2 and ERK1/2, but not DDR1 [63] and that DDR2 regulates the adhesion of fibrobla

  As discussed in the introduction, many pregnant women take medications such as nifedipine and indinavir, which are considerably metabolized by CYP3A [26]. Previous reports have also shown increased CYP3A activity following pregnancy [7], [9], which is consistent with our results. However, previous s

  The data presented above clearly indicate an important role of eIF4E for the nucleocytoplasmic transport of the human iNOS mRNA. To analyze the sequence elements of the iNOS mRNA that are important for this eIF4E-mediated transport we performed transient transfection experiments using constructs con

  Several lines of evidence suggest that the anxiety provoking behavioral effects of CRF involve CRF1 receptors. CRF1 knockout mice show increased anxiolytic-like activity in the elevated plus maze and a tendency to enter the illuminated region of a light–dark box [49], [52]. In addition, studies usin

  Liver metabolic programming begins in utero. Aiming to find a reason for the decreased lipid catabolism enzyme expression observed in fetuses and offspring from SFD rats, we studied the effect of leptin on liver catabolism in fetuses from control and SFD rats. Livers from control fetuses responded t

  It is well known that Doxorubicin-induced cardiotoxicity occurs via p53-mediated apoptosis (Lorusso et al., 2007). However, there are few studies elucidating the mechanism of HFS induced by PLD. We found that PLD induces keratinocyte apoptosis in a very low dose, and the damage induced by PLD cannot
