Figure Lengend Snippet: Sponging relationship between BACE1-AS and miR-6805-5p in HCT-8 cells during C. parvum infection. (A) Subcellular location of BACE1-AS in HCT-8 cells. HCT-8 cells were seeded on a coverslip and were infected with C. parvum for 24 h and then applied for FISH analysis of BACE1-AS using probes conjugated with cy3, with 18S localized in the cytoplasm as a control. The nucleus was visualized by DAPI staining. (B) The mRNA levels of miR-6805-5p in HCT-8 cells transfected with pcDNA3.1(+)-BACE1-AS plasmid or si-BACE1-AS following C. parvum infection at 24 hpi by using RT-qPCR. (C) Putative binding site between BACE1-AS and miR-6805-5p predicted by LncBook. (D) The luciferase activity in HCT-8 cells co-transfected with miR-6805-5p mimics and pmirGLO-BACE1-AS-WT or pmirGLO-BACE1-AS-MUT. Statistical analysis was conducted by using a non-parametric t -test. * P < 0.05, ** P < 0.01. WT, wild type.
Article Snippet: In this study, the luciferase reporter plasmids of wild-type BACE1-AS (BACE1-AS -WT), mutant BACE1-AS (BACE1-AS -MUT), wild-type IRF3 ( IRF3 -WT), and mutant IRF3 ( IRF3 -MUT) were constructed by cloning BACE1-AS, the miR-6805-5p binding site-mutated BACE1-AS, 3′ UTR region of IRF3 , and the miR-6805-5p binding site-mutated 3′ UTR region of IRF3 into pmirGLO vectors (Promega, Madison, WI, USA), respectively.
