MKI67 and liver lymphoma: We could not find a significant immunohistochemical correlation between αB-Crystallin expression and Ki67 proliferation marker nor matrix metalloproteinase‐9 (MMP-9) expression in lung adenocarcinomas, however Ki67 in liver lymphoma and MMP9 in hepatocellular carcinoma were correlated with high αB-Crystallin (Additional file 1: Fig. S6b).
