STC1 and neoplasm: STC1 is a glycoprotein found in the endocrine glands of the fish kidney, and it is considered a tumor cell apoptosis‐inducing factor.17GPM6A is a transmembrane protein widely distributed on the neuronal cells surface in the central nervous system; it is believed that GPM6A is one of the pathogenic genes of human lymphatic leukemia and is closely related to apoptosis.13 Therefore, we chose STC1 and GPM6A for RT‐qPCR analysis.
