ATP1A1 and glioblastoma: qPCR (Figure S1A) and western blot (Figure S1B) analyses showed that ATP1A1 expression was markedly decreased in cells transfected with sh-ATP1A1-1 or sh-ATP1A1-2 vector when compared with cells transfected with sh-NC vector and non-transfected cells (GBM GSCs1-N and GBM GSCs2-N).
