Indeed, the ARV825 treatment substantially reduced HCC development (Fig. 2a, b), coincident with the reduction of the senescent HSC number in the obesity-induced HCC mouse model, as judged by the immunofluorescence (IF) staining analysis using the combination of antibodies against αSMA (activated HSCs marker) and p21 (senescence marker) or IL6/Groα (SASP markers)13 (Fig. 2c). The gene discussed is ACTA1; the disease is Obesity.
