a Quantitative analysis of primary and secondary sphere formation by CC-1 and CC-2 cells. b Quantitative analysis of sphere formation by CRC cells treated with perifosine or LY294002. c Flow cytometry analysis of LGR5 expression in CC-1 and CC-2 cells. d qRT-PCR analysis of stem cell markers, CD133, C-MYC, LGR5, ALDH1A1, NANOG and CXCR4 genes expression in CC-1 and CC-2. e Immunoblots showing p-Akt, Akt, LGR5, C-myc and GAPDH (loading control) expression levels in PIK3CA mutant tumor tissue comparing with that without mutation. f Immunoblots showing p-Akt, Akt, LGR5, C-myc and GAPDH (loading control) expression levels in CC-1 cells treated with perifosine, LY294002 or BpV (phen) comparing with vehicle
