Furthermore, immunostaining of consecutive sections revealed significant expression of GLO1, CXCL1, and CXCR2 proteins in tumor epithelial cells [Fig. 5C (b), (d), and (f)], in contrast to no or low expression in noncancerous tissues [Fig. 5C (a), (c), and (e)]. The gene discussed is CXCL1; the disease is neoplasm.
