In contrast, very high level of CTIP2 was detected in head and neck cell lines (SCC4, SCC25, HSC2, HAN HN2) and also in other carcinomas such as epidermoid carcinoma from submaxillary salivary gland (A253) and breast carcinoma (MCF7) (see Fig. 2E). Here, BCL11B is linked to squamous cell carcinoma.
