p53(ΔCp44) became more abundant in cell lysates treated with m‐calpain (from 0.01 units to 0.08 units) as the course of the infection progressed (Figure 5B, left column, middle, and lower panels), which was consistent with the results of immunoblot analysis of the whole‐cell lysates (Figure 1). The gene discussed is TP53; the disease is infection.
