  [125I] α-bungarotoxin competes with ACh, an endogenous activator of α7-nACh receptors by binding to the ACh binding site on the receptor (Albuquerque et al., 2009). For this reason, the effect of curcumin was investigated on the specific binding of [125I] α-bungarotoxin. Saturation curves for the bi

  Discussion The regulation of intracellular cholesterol levels is a biological process of vital importance for cellular function and integrity, and involves robust transcriptional and post-transcriptional mechanisms that are sensitive to metabolic feedback control. Amongst post-transcriptional mec

  Studies have shown that the cultivation of BMSCs under hypoxic conditions, treating with cytokines (such as HGF, IGF-1 and IL-6) and viral-mediated CXCR-4 gene delivery have been shown to re-establish CXCR-4 expression on the surface of stem MDV 3100 (Liu et al., 2010, Liu et al., 2014a, Ziaei et a

  Perturbations in trilithium are known to induce apoptosis. Our results show that a fraction of the DT40YB-1b+/− cells, in addition to becoming tetraploids, undergo apoptotic cell death. Similar observations linking polyploidy and apoptosis have been made in the past [23], [30], [31], [32], [33], [3

  Among the different factors that modulate Schwann cell biology, several studies pointed out the role played by neuroactive steroids, in particular progesterone (P4) and its derivatives dihydroprogesterone (DHP) and allopregnanolone (ALLO). Schwann PF-04691502 are steroidogenic, possessing the entir

  The first ones class A receptors found as heterodimers were reported by Gomes et al. (2000), who identified a heteromer constituted by two subtypes of opioid receptors (μ and δ) in heterologous cells. The same year, Ginés et al. (2000) showed the first heteromer composed of two different receptors,

  Structural and biochemical features of pol X family polymerases The X-family DNA polymerase (polX) is specialized in DNA repair. This family is composed of four different DNA polymerases: pol β, pol λ, pol μ and TdT. Only three members of the polX family possess an N-terminal BRCT (BRCA1 carboxy-

  As for antiviral activity, eight out of 23 synthesized compounds were active against influenza B virus with EC50 values in the range of 0.19–39 μM. Four of the eight influenza B hits were active against influenza A and two were also active against RSV (4 and 6, EC50 = 0.40 and 1.8 μM, respectively).

  In order to derive a better understanding of the results from our SAR study, we utilized Glide to model the binding of the SAR compounds with the non-active site pocket of TS-DHFR shown in C. The majority of models position the phenolic moiety of these compounds within the non-active site pocket, wh

  Experimentally measured DGAT activity was first reported by Weiss et al. (1960) and several different types of DGAT enzyme have since been described in plants [12,41,42]. As recently as 2011 there appeared to be just two DGAT enzymes both in plants and in other eukaryotes, namely DGAT1 and DGAT2 [43

  Cell migration and invasion are central processes in the development and metastasis of cancer. The regulation of cell migration by DDR1 has been reported in many types of cancer cell lines; however, conflicting results have been reported regarding the inhibitory as well as promotive effects of DDR1

  DNA promoter hypermethylation is an important mechanism in epigenetic modulation of gene expression.[16], [17], [18] When the promoter CpG island of a gene is hypermethylated, the transcription and its associated function of the gene will be subsequently altered.[19], [20], [21] In human cancers, we

  MTT results show that, both pancreatic cell lines were quite sensitive to camptothecin (CPT), a well known topoisomerase I poison. Interestingly, CPT does not show any selectivity over cancer cell lines probably due to the duplication times for cancerous (MIA PaCa-2) and immortalized healthy (HPDEC)
