HIF1A and hepatocellular carcinoma: Lastly, by directly interacting to the promoter of SH3BP5-AS1, HIF-1α could control the transcription of the gene.<h4>Conclusions</h4>Our research suggests that SH3BP5-AS1 controls miR-6838-5p/PTPN4 in order to act as a new carcinogenic LncRNA during the growth of HCC cells.<h4>Methods</h4>The expression levels of SH3BP5-AS1, miR-6838-5p and PTPN4 were detected by qRT-PCR and Western blot.
