Notably, the tumour suppressive effect of ARV825 on HCT116 xenograft mice treated with DXR coincided with an increase of cleaved caspase-3 (an apoptosis marker), together with γH2AX (a DNA damage marker), and LC3B (an autophagy marker) in tumour tissues (Fig. 3e). The gene discussed is CASP3; the disease is neoplasm.
