PDLIM7 and neoplasm: The H&E-stained sections of the tumors showed that the tumor tissue cells in the GSH-PBAE-LMP-g4 group had condensed nuclei, significantly enlarged intercellular spaces, and loose connections between cells, in contrast to the intact cellular morphology of the tumor tissues in the saline and LMP-g4 groups (Fig. 6k), suggesting that the GSH-PBAE-LMP-g4 NPs exhibited strong tumor cytotoxicity and tumor growth inhibition.
