MAP1LC3B and laryngotracheoesophageal cleft: 28 The report of Chen L et al. showed that miR-101 lowered the autophagy, proliferation and enhanced the apoptosis in LC cells.29 In addition, studies have indicated that compared with normal laryngeal tissues, HPV-infected respiratory papilloma tissues have more LC3B expression and autophagosomes.20 In this study, we found that HPV transfection enhanced the autophagy of LC cells.
