Abstract
BackgroundWe aimed to explore the roles of basic leucine zipper and W2 domains (BZW) 2 in the human papillomavirus-infected laryngeal papillomatosis.MethodsIn the present study, BZW 2 knockdown and overexpressed cell lines were constructed. CCK-8 and colony formation assays were used to determine cell proliferation. Caspase-3 activity and nucleosomes fragmentation assays were used to determine cell apoptosis. qRT-PCR and Western blot were employed to evaluate the mRNA and protein levels of target genes, respectively. Luciferase and biotin-coupled miRNA pulldown assays were used to examine the interactions between mRNA and mRNA.ResultsWe observed the levels of BZW2 were up-regulated in the laryngeal papilloma (LP) tissues as compared with adjacent tissues. The knockdown of BZW2 significantly inhibited cell proliferation and promoted cell apoptosis in the LP cells. Additionally, we identified the expressions of BZW2 negatively regulated by miR-4500. Luciferase and biotin-coupled miRNA pulldown assays demonstrated that LINC00174 competed with the BZW2 for binding with miR-4500. Moreover, the results showed that LINC00174/miR-4500/BZW2 axis regulated cell proliferation and apoptosis.ConclusionOur results demonstrated that the regulation of LINC00174/miR-4500/BZW2 axis might be used as an effective strategy for treatment of human papillomavirus-infected laryngeal papillomatosis.

Summary
We aimed to explore the roles of basic leucine zipper and W2 domains (BZW) 2 in the human papillomavirus-infected laryngeal papillomatosis. Laryngeal papillomatosis (LP) is a rare disease caused by human papillomavirus (HPV) infection. MicroRNAs (miRNAs) have been implicated to play an important role in various biological processes including cell migration, proliferation, invasion and apoptosis [4,5,6]. Liu et al Cancer Cell Int (2020) 20:471 cardiovascular disease, neurological disease, and many types of cancers [6,7,8,9]. The expressions of miRNAs are regulated by other miRNAs or transcription factors when the cells encounter stimuli [7]. It is worthwhile to identify miRNAs with regulatory effects in the occurrence and development of LP
