TP53 and lymphoma: These cells were chosen as representative of different types of DLBCL: OCI‐LY19 comes from a germinal center DLBCL; RIVA (also known as RI‐1) is an ABC‐like lymphoma subtype, like U2932 (however, the latter has a mutated p53 while the former expresses the wild type form, which influences their sensitivity and response to chemotherapeutic drugs).
