LINC00301 and non-small cell lung carcinoma: To clarify which FOXC1 binding sites are responsible for the FOXC1-induced transcriptional activation of LINC00301, chromatin immunoprecipitation (ChIP) assay was conducted to identify that FOXC1 could directly bind to site 6 (− 1395 to − 1388 nt) on the LINC00301 promoter in NSCLC cell lines (Fig. 5n).
