LncRNA AFAP1-AS1 Modulates Gastric Cancer Cell Proliferation


13 and hepatocellular carcinoma.
14,15 In a previous analysis of the lncRNA expression profile using a microarray assay, we found that AFAP1-AS1 was upregulated in six GC tissues compared with paired non-cancerous tissues. To investigate the relationship between AFAP1-AS1 and GC, the expression of AFAP1-AS1 was further verified in a study involving a larger sample size composed of tissues and six different GC cell lines. In addition, the potential functions of AFAP1-AS1 on the proliferation, migration, and invasion of GC cells was also investigated in this study.
Materials and Methods
Tissue Samples and RNA Extraction
In this investigation, 97 fresh frozen GC and their paired non-cancerous tissues were collected at Fuzhou General Hospital, which were used to assess the expression of AFAP1-AS1. The collection and preservation of fresh GC tissue samples were carried out as previously described. ....

Inhibition of Long Non-Coding RNA KCNQ1OT1 Attenuates Neuroinflammatio


Knocking Down KCNQ1OT1 Suppressed LPS-Induced Neuroinflammation and Neuronal Apoptosis in HMC3 Cells
For further exploring the function of KCNQ1OT1, we transfected HMC3 cells with pc-KCNQ1OT1 or si-KCNQ1OT1. The expression of KCNQ1OT1 was evaluated by RT-qPCR. Compared with control cells (cells transfected with pc-NC or si-NC), the expression of KCNQ1OT1 in HMC3 cells transfected with pc-KCNQ1OT1 was significantly increased, while the expression of KCNQ1OT1 in cells transfected with si-KCNQ1OT1 was significantly decreased (Figure 2A). Subsequently, we used RT-qPCR and ELISA kits to examine the expressions of TNF-α, IL-1β and IL-6 to evaluate the inflammatory response. The results indicated that LPS treatment markedly promoted the expression levels of inflammatory cytokines TNF-α, IL-1β and IL-6 in HMC3 cells; overexpression of KCNQ1OT1 promoted the expressions of inflammatory cytokines, while KCNQ1OT1 knockdown inhibited their expression (Figure 2B and C). The expression o ....
