Cancer is a major disease with millions of patients diagnosed each year with high mortality around the world. Various studies are still going on to study the further mechanisms and pathways of the cancer cell proliferation. Fucosylation is one of the most important oligosaccharide modifications involved in cancer and inflammation. In cancer development increased core fucosylation by FUT8 play an important role in cell proliferation. Down regulation of FUT8 expression may help cure lung cancer. Therefore the computational study based on the down regulation mechanism of FUT8 was mechanised. Sapota fruit extract, containing 4-Ogalloylchlorogenic acid was used as the inhibitor against FUT-8 as target and docking was performed using in-silico tool, Accelrys Discovery Studio. There were several conformations of the docked result, and conformation 1 showed 80% dock score between the ligand and the target. Further the amino acids of the inhibitor involved in docking were studied using another tool, Ligplot. Thus, in-silico analysis based on drug designing parameters shows that the fruit extract can be studied further using in-vitro techniques to know its pharmacokinetics.

Abstract Objectives The aim of this study was to investigate the effect of lncRNA-SNHG15 in bladder carcinoma using cell lines experiments and the relationship between clinical characteristics and lncRNA-SNHG15 expression was analyzed. Methods Bladder cancer tissues and near-cancer tissues were collected. The real-time PCR (RT-PCR) was used to detect the expression of lncRNA-SNHG15 in tissues and cell lines. The expression of lncRNA-SNHG15 was downregulated by interference (siRNA), as detected by RT-PCR, that was used to determine the efficiency of the interference. CCK-8 and Transwell assays were used to evaluate the effect of lncRNA-SNHG15 on the proliferation and invasion capability of bladder cancer cells. The t-test was used for Statistical analyses, which were carried out using the Statistical Graph pad 8.0.1.224 software. Result The expression of lncRNA-SNHG15 was up regulated in 5637, UMUC3 and T24 cell lines compared with corresponding normal controls (P < 0.05). Up regulation was positively related to tumor stage (P = 0.015). And tumor size (P = 0.0465). The down-regulation of lncRNA-SNHG15 with siRNA significantly inhibited UMUC3 and T24 cell proliferation and invasion. Conclusion This study showed that lncRNA-SNHG15 is overexpressed in bladder cancer tissues and (5637, UMUC3 T24) cell lines. Up regulation was positively related to tumor stage (P = 0.015), and tumor size (P = 0.0465). Down-regulation of lncRNA-SNHG15 by siRNA significantly inhibited UMUC3 and T24 cell proliferation and invasion, indicating a potential molecular target for future tumor targeted therapy.

miRNA has always been a hot spot research. We assessed the effect of down-regulation of miR-23b-3p on the differentiation of acute myeloid leukemia (AML). Human AML cell line U937 was divided into blank group, NC group and miR-23b-3p low expression group (transfected with miR-23b-3p inhibitor) and miR-23b-3p followed by analysis of WT1 level and relationship between miR-23b-3p and WT1 by dual luciferase reporter assay. All-trans retinoic acid is used to induce differentiation, and then the morphological changes of cells and CD11b level were detected. When miR-23b-3p level was reduced, WT1 mRNA and protein level was also decreased. Dual luciferase assay showed that miR-23b-3p bound to WT1 3’-UTR. Inhibition of miR-23b-3p significantly decreased cell proliferation. Swiss Giemsa staining showed that most of cells were in the differentiation stage with low miR-23b-3p expression. The differentiation marker CD11b was significantly higher than other groups, indicating that low miR-23b-3p expression can promote cell differentiation and reduce cell proliferation to a certain extent. Under low miR-23b-3p expression, the positive rate of CD11b was significantly increased. Down-regulating miR-23b-3p can inhibit WT1 to a certain extent and promote the differentiation of AML, which provides a guidance for the gene-level treatment of AML.
