Human papillomavirus (HPV) is a risk factor for lung cancer. However, the mechanisms underlying is not known. Long noncoding RNAs (lncRNAs) have been found to play an important part in the occurrence and development of lung cancer due to their particular characteristics. HPV induced lung carcinogenesis are incompletely defined. We aim to screen and clarify the functions of lncRNAs that are differentially expressed in HPV related lung cancer. We find that lncRNA SNHG1 is upregulated in lung cancer cells infected with HPV16 E6 by qRT-PCR. Further results demonstrate that SNHG1 overexpression facilitates the tube formation of lung cancer cells in vitro. Our results also indicate that SNHG1 might function in lung cancer by binding with EGFR. Further studies indicate that SNHG1 overexpression can activate nuclear factor κb (NF-κB) pathway which increases the expression of interleukin-6 (IL-6). We also find IL-6 can activate STAT3 pathway which promote the VEGF-D expression. These results expanded our understanding of SNHG1 as a new avenue for therapeutic intervention against lung cancer progression. Upregulation of SNHG1 by HPV infection might be an undefined link between lung cancer and HPV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
