Objective:To investigate the expression and correlation of cancer stem-like cell(CSC)markers CD44
ALDH1
NANOG and hypoxia inducible factor-1α(HIF-1α) in oral squamous cell carcinoma. Methods:Expression of CD44
ALDH1
NANOG and HIF-1α in 40 cases of oral squamous cell carcinoma tissues
collected form the Affiliated Stomatological Hospital of Chongqing Medical University
10 cases of metastatic lymph node tissues
10 cases of non cancer tissues and 10 cases of normal lymph node tissues were detected using immunohistochemistry.The correlations of the expression of the makers and HIF-1α as well as their correlations with tumor differentiation
histological type
clinical stage and lymphoid metastasis were analyzed using Fisher exact test and KruskalWallis test. Results:(1)The expressions of CD44
NANOG
HIF-1α were significantly higher than those in non-cancer tissues(P
CD44
=0.000;P
NANOG
=0.000;P
HIF-1α
=0.000).(2)Only expression of CD44 was positively correlated with HIF-1α expression in oral squamous cell carcinoma(r
s
=0.498
P=0.027).(3)Expression of CD44
ALDH1
NANOG and HIF-1α was not correlated with tumor differentiation
histological type and lymphoid metastasis. Conclusion:The positive expressions of CD44
NANOG and HIF-1α in oral squamous cell carcinoma are higher than those of non-cancer tissues. Expression of CD44 showed significant correlation with HIF-1α expression.This may suggest that the combined examination of CD44
NANOG and HIF-1α may be significant for the early diagnosis of oral squamous cell carcinoma.
