PG - 97-107 LID - 10.3233/CBM-181947 [doi] AB - Cancer stem cells (CSCs) have the ability to dictate tumor initiation, recurrence, and metastasis. Here, we examined the expression of aalpha2delta1+ in laryngeal cancer tissues and further determined the effect of alpha2delta1 on the migratory ability and tumorigenicity of laryngeal cancer cells. Immunofluorescence staining revealed that alpha2delta1 was positive in 13 (13/16, 81.25%) cases in laryngeal squamous cell carcinoma (LSCC) tissues, 7 (7/16, 43.75%) cases in paracancerous tissues and only 2 (2/16, 12.5%) cases in normal tumor tissues. Our quantitative RT-PCR assays further showed that alpha2delta1+ LSCC cells expressed significantly higher levels of stem cell-associated genes and drug efflux and resistance genes versusalpha2delta1- cells. Sphere-forming assays demonstrated higher sphere-forming efficiency in the alpha2delta1+versusalpha2delta1- subpopulation. Our Matrigel assays showed that alpha2delta1+ cells exhibited significantly greater invasive and migratory ability than alpha2delta1- cells. Furthermore, the percentage of purified alpha2delta1+ in TU686 and TU212 cells treated cisplatin or paclitaxel was significantly higher than that of the control group. Tumor xenograft assays revealed that the tumorigenicity of alpha2delta1+ cells was much higher than alpha2delta1- cells. In conclusion, a alpha2delta1+ subpopulation with CSC-like property was present in laryngeal cancer and possessed high self-renewal activity and was sufficient for tumor growth, differentiation, migration, invasion, and chemotherapeutic resistance. They could represent a promising therapeutic target for LSCC.
