BRD4 and neoplasm: To further determine this point, the protein expression levels in tumor samples from animal models were probed by immunohistochemical techniques and found that the proportions of BRD4‐ and Notch1‐positive cells were slightly increased in T@Glu‐NPs and significantly decreased in tumor samples from both A@Glu‐NPs and T+A@Glu‐NPs (Figures 4J,K, and 7H,I).
