Fig. 3From: Sulforaphane inhibits self-renewal of lung cancer stem cells through the modulation of sonic Hedgehog signaling pathway and polyhomeotic homolog 3SFN inhibits expression of Shh, Gli1, Smo and PHC3 in human lung CSCs. a, b QPCR data shows that the mRNA levels of Shh, Gli1, SMO and PHC3 were significantly inhibited when lung CSCs were treated with SFN, compared with the control group. c–e Western blotting data shows that the protein levels of Shh, Gli1, SMO and PHC3 were significantly inhibited when lung CSCs were treated with SFN, compared with the control group. N = 3, Data are presented as mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
