To investigate whether Pgrmc1 regulates pro-inflammatory response via EGFR, we performed co-immunostaining of PGRMC1 and EGFR in HCC samples, and found co-localization of PGRMC1 and EGFR in non-parenchymal cells, rather than HCC cells (Figure S7). The gene discussed is EGFR; the disease is hepatocellular carcinoma.
