LINC01123 and head and neck squamous cell carcinoma: When total RNA was extracted from HNSCC cell lines (SCC-9, SCC-15, SCC-25, Fadu, and CAL-27) and human oral epithelial cells (HOEC) and the level of LINC01123 expression detected by qRT-PCR, high LINC01123 expression was seen in all HNSCC cell lines, among which the expression of LINC01123 was the highest in CAL-27.
