Itraconazole affects human cSCC development by regulating HMGCS1 transcription. (A) The relative mRNAs expression levels of HMGCS1 were presented by qRT-PCR. (B) The relative proteins expression levels of HMGCS1 were presented by western blot. qRT-PCR analysis (C) and western blot (D) were performed to detect HMGCS1 expression in A431 cells that were transfected with sh-Con, sh-HMGCS1#2, sh-HMGCS1#3, and sh-HMGCS1#5. (E) A431 sh-Con and A431 sh-HMGCS1#2 cells were treated with indicated concentrations of itraconazole for 48 h. Inhibition of cell viability was analyzed by CCK8 assay. (F) The relative luciferase activity was detected by dual-luciferase reporter gene activity assay. [mean ± SD (error bars), n = 3; *p ≤ .05; **p ≤ .01; ***p ≤ .001, compared with control group].
