Cancer&Entry Information

Cancer Name	thyroid cancer
ICD-0-3	C73.9
Methods	qPCR, Western blot
Sample	thyroid cancer tissues, cell lines (CAL-62, WRO and FTC-133)
Expression Pattern	up-regulated
Function Description	The expression level of BANCR differed between cultured thyroid cancer cell lines; BANCR expression was lower in the BCPAP cell line than that observed in the CAL-62, WRO and FTC-133 cell lines. Western blot analysis and flow cytometry revealed that overexpression of BANCR in the BCPAP cell line resulted in increased expression of the cancer stem cell markers, LGR5 and EpCAM. Single-clone formation experiments showed that upregulated expression of BANCR in the BCPAP cell line promoted an increase in the number of clones formed. Similarly, in microsphere formation experiments, overexpression of BANCR resulted in increased number and size of microspheres compared with the control cell line. Western blotting experiments showed that BANCR overexpression in BCPAP upregulated the expression of phosphorylated c-Raf, MEK1/2 and ERK1/2. Inhibition of c-Raf via U0126 decreased the expression of LGR5 and EpCAM, as well as phosphorylated levels of c-Raf, MEK1/2 and ERK1/2 in the BCPAP cells, compared to levels in the DMSO controls. In the xenograft mouse model, BANCR overexpression in the thyroid cancer cells significantly increased tumor growth.
