Finally, through rescue assay, we found that KDM3A countervailed miR-216a-5p mediated regulation of neuropathic pain via the Wnt/β-catenin signaling pathway. To sum up, our study confirmed that miR-216a-5p alleviated neuropathic pain in rats by targeting KDM3A and inactivating the Wnt/β-catenin signaling pathway, which may open a new and useful way for treatment of neuropathic pain.In spite of advancements in breast cancer therapy, this disease is still one of the significant causes of women fatalities globally. Dysregulation of miRNA plays a pivotal role in the initiation and progression of cancer. Therefore, the administration of herbal compounds with anticancer effects through controlling microRNA expression can be considered as a promising therapy for cancer. Oleuropein is the most prevalent phenolic compound in olive. Given its domestic consumption, low cost, and nontoxicity for human beings, oleuropein can be used in combination with the standard chemotherapy drugs. To this end, we examined the effect of oleuropein on two breast cancer cell lines (MCF7 and MDA-MB-231). Our findings revealed that oleuropein significantly decreased cell viability in a dose- and time-dependent manner, while it increased the apoptosis in MCF7 and MDA-MB-231 cells. In the presence of oleuropein, the expression levels of miR-125b, miR-16, miR-34a, p53, p21, and TNFRS10B increased, while that of bcl-2, mcl1, miR-221, miR-29a and miR-21 decreased. The findings pointed out that oeluropein may induce apoptosis via not only increasing the expression of pro-apoptotic genes and tumor suppressor miRNAs, but also decreasing the expression of anti-apoptotic genes and oncomiR. Consequently, oleuropein can be regarded as a suitable herbal medication for cancer therapy.Coumarins exhibit a wide variety of biological effects, including activities in the cardiovascular system and the aim of this study was to evaluate the vascular therapeutic potential of 7-Hydroxicoumarin (7-HC). Dabrafenib ic50 The vascular effects induced by 7-HC (0.001 μM-300 μM), were investigated by in vitro approaches using isometric tension measurements in rat superior mesenteric arteries and by in silico assays using Ligand-based analysis. Our results suggest that the vasorelaxant effect of 7-HC seems to rely on potassium channels, notably through large conductance Ca2+-activated K+ (BKCa) channels activation. In fact, 7-HC (300 μM) significantly reduced CaCl2-induced contraction as well as the reduction of intracellular calcium mobilization. However, the relaxation induced by 7-HC was independent of store-operated calcium entry (SOCE). Moreover, in silico analysis suggests that potassium channels have a common binding pocket, where 7-HC may bind and hint that its binding profile is more similar to quinine's than verapamil's. These results are compatible with the inhibition of Ca2+ release from intracellular stores, which is prompted by phenylephrine and caffeine. Taken together, these results demonstrate a therapeutic potential of 7-HC on the cardiovascular system, making it a promising lead compound for the development of drugs useful in the treatment of cardiovascular diseases.Among the 20 or so Leishmania spp. described as pathogenic for humans, those of the Leishmania donovani complex are the exclusive causative agents of systemic and fatal visceral leishmaniasis. Although well studied, the complex is taxonomically controversial, which hampers clinical and epidemiological research. In this work, we analysed 56 Leishmania strains previously identified as L. donovani, Leishmania archibaldi or Leishmania infantum, isolated from humans, dogs and sandfly vectors throughout their distribution area. The strains were submitted to biochemical and genetic analyses and the resulting data were compared for congruence. Our results show i) a partial concordance between biochemical and genetic-based data, ii) very limited genetic variability within the L. donovani complex, iii) footprints of frequent genetic exchange along an east-west gradient, marked by a widespread diffusion of alleles across the geographical range, and iv) a large-scale geographical spreading of a few genotypes. From a taxonomic point of view, considering the absence of relevant terminology in existing classes, the L. donovani complex could be treated as a single entity.This research examined if planning and self-monitoring could be distinguished in terms of quality and quantity, and if differences in the uses of these strategies were associated with distinct eating outcomes. In Study 1 (n = 355), the structure of a new scale designed to measure planning and self-monitoring in terms of quality (i.e., nutrient intake) and quantity (i.e., calories and portion sizes) was examined through Confirmatory Factor Analysis. Structural equation models were also tested in which the relationships between the proposed strategies, healthy and unhealthy eating behaviors and bulimic symptoms, as well as BMI, were examined. The purpose of Study 2 (n = 318) was to replicate the results found in Study 1, using a different sample. Overall, a 6-factor structure was found for the scale and results revealed that strategies related to the quality of eating were more strongly and positively associated with healthy eating and more strongly and negatively associated with unhealthy eating behaviors, whereas strategies related to the quantity of eating were more strongly and positively associated with bulimic symptoms and BMI. Results are discussed in terms of implications for health professionals who wish to improve individuals' eating behaviors and/or weight.Chalcone synthase (CHS, EC 2.3.1.74) is one of the key and rate-limiting enzymes of phenylpropanoid pathway which plays superior roles in the production of secondary metabolites. In the present study a full-length cDNA of CHS gene was isolated and characterized from Coelogyne ovalis, an orchid of ornamental and medicinal importance. The CHS gene sequence from C. ovalis (CoCHS) was found to be 1445 bp and comprised an open reading frame of 1182 bp, encoding for 394 amino acid residues. Further, the sequence alignment and phylogenetic analysis revealed that CoCHS protein shared high degree of similarity with CHS protein of other orchid species. It also confirmed that it contained all four motifs (I to IV) and signature sequence for the functionality of this gene. Structural modeling of CoCHS based on the crystallographic structure of Freesia hybrida indicated that CoCHS had a similar structure. Quantitative polymerase chain reaction (qPCR) disclosed that CoCHS was expressed in all tissues examined, with the highest transcript being in leaves, followed by pseudobulbs and roots.
