  2022-06-13

  

  Most studies of HIF-1α have focused on its transcriptional activity-dependent functions. However, our results indicate that the oxidative stress-related effects of mtHIF-1α occur independently of its translocation to the nucleus and do not require its transcriptional activity. In fact, several studi

  Resistance to targeted therapy The idea of treating HER2 mutant tumors with specific therapies is relatively new and, as a consequence, little is known about the potential mechanisms of resistance to anti-HER2 agents in this setting. Primary resistance may be mediated by the presence of on-target

  Heme and the HO system Heme, a complex of iron and protoporphyrin IX, has versatile functions, which are critical for the survival of all aerobic organisms including mammalians and bacteria [9]. The central iron in heme facilitates six ligand binding sites [10], four of which are occupied by nitr

  The 50% inhibitory concentration of atrial natriuretic factor at midgestation and term are –7.4 ± 0.12 and –7.38 ± 0.11, respectively, demonstrating no gestational age dependency in the effect of atrial natriuretic factor on spontaneous contractile activity. Diethyl amine/nitric oxide starts to inh

  2022-06-13

  

  Etoposide (VP-16), a semisynthetic podophyllotoxin derivative agent, is widely used as a chemotherapic treatment for many cancers (Hande, 1998). VP-16 has been known that its activity is mediated by the interaction with topoisomerase II (an ATP-dependent nuclear enzyme) which regulates DNA topology

  For several years, CXCL17 had been classified as an orphan chemokine, until Maravillas-Montero et al. claimed that orphan G-coupled protein receptor GPR35 is the receptor of CXCL17 [15], [16]. However, no following research has been produced to further explore the function of the CXCL17-CXCR8 (GPR3

  2022-06-13

  

  Recently, several groups reported that four orphan receptors, GPR40, GPR41, GPR43, and GPR120, can be activated by free fatty acids. Short-chain fatty acids are specific agonists for GPR41 and GPR43 . Medium and long-chain fatty acids can activate GPR40 and GPR120 . Our previous report showed that

  It may seem counterintuitive that a lymphocyte which is unable to proliferate could have neoplastic potential since the very definition of neoplasia is one of autonomous clonal expansion of a cell. The lack of co-stimulatory molecules CD27 and CD28 can potentially be overcome by activating NK cell r

  2022-06-13

  

  To verify DNA glycosylase/AP lyase activity we have employed a simple and efficient method to investigate based on fluorescein-labeled duplex oligonucleotides read on an automated sequencer (Allgayer et al., 2013, Lopes et al., 2007, Lopes et al., 2008). This approach using purified CpMutY proteins

  The HH signaling has also been implicated in the regulation of cancer stem CU CPT 4a synthesis (CSC) by promoting their self-renewal [53]. Activated HH signaling has been identified in CSCs of many solid tumors, such as glioblastoma, breast, colon, pancreatic cancer, melanoma, and hematological mal

  Introduction RNA splicing occurs in the nucleus when noncoding sequences (introns) are removed from the pre-mRNA transcript and coding sequences (exons) are joined to form a mature mRNA [1,2]. This reaction is catalyzed by a multiprotein complex called spliceosome. The spliceosome consists of five
