Abstract (original English)
Objective To investigate the expression levels and mechanisms of microRNA (miRNA) 26a (miR-26a) and phosphatase and tensin homolog (PTEN) in patients with human papillomavirus (HPV)-induced condyloma acuminatum (CA) and penile squamous cell carcinoma (PSCC). Methods Thirty-one patients with HPV-positive CA and 28 with HPV-positive PSCC were included in this retrospective, cross-sectional study. PTEN mRNA and miR-26a levels in lesion tissues, blood, and urine were analyzed by quantitative reverse transcription polymerase chain reaction, and PTEN protein was detected by western blot and enzyme-linked immunosorbent assay. Cell proliferation was assessed by MTT assay. The interaction between miR-26a and PTEN was predicted by bioinformatics analysis and confirmed by dual luciferase reporter assay. Results PTEN mRNA and protein levels were significantly lower and miR-26a levels were significantly higher in all samples from patients with PSCC compared with the CA group. Bioinformatics analysis and luciferase reporter assay confirmed PTEN as a target gene of miR-26a. Up-regulation of miR-26a significantly increased the proliferation of Penl1 PSCC cells. Conclusions PTEN expression is down-regulated and miR-26a levels are up-regulated in PSCC compared with CA. PTEN is a direct target gene of miR-26a. These results suggest that miR-26a might regulate HPV-positive progression from CA to P
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • Without an adequate control group, treatment effects cannot be separated from other factors.
Evidence level
