Fig. 5From: Upregulation of the long non-coding RNA CASC9 as a biomarker for squamous cell carcinomaExpression of CASC9 in HNSCC cell lines. (a) Relative expression of CASC9 determined by RT-qPCR was heterogeneous across 21 HNSCC cell lines, but mostly increased compared to benign HaCat cells. (b) CASC9 overexpression and downregulation (sh) in stably transfected cells was validated by RT-qPCRBack to article page
