PLPP4 and neoplasm: ENCORI pancancer co-expression analysis predicted that there was no correlation between the expression of miR-892b and PPAPDC1A (PLPP4) in BC patients (Supplementary Figure 1B, p > 0.05) and miR-892b showed extremely poor expression in most clinical tumor samples, so these clinical sample data cannot reflect the regulatory effect between PPAPDC1A and miR-892b.
