MKI67 and neoplasm: Interestingly, no obvious lessons were found in the main organs of mice treated with the combination of cisplatin and GRN A. IHC immunological analysis also revealed that GRN A could sensitize the tumor to cisplatin; the brown particle presented the cellular proliferation marker (Ki-67) expression, as shown in the Figure 6b, and the manual counting data for Ki-67 was performed as described by Yeo, M.K., et al. [28].
