PSRC1 and small cell lung carcinoma: The active pathways in the PSRC1 high-expression group indicated the possible presence of cell division process which is mediated by the regulatory role of PSRC1 in SCLC, and the active pathways in the PSRC1 low-expression group indicated the possible presence of humoral immune responses and the metabolic processes of cytochrome P450 which are mediated by the regulatory role of PSRC1 in SCLC.
