Next, we analyzed the expression of AEBP1-correlated gene BGN (R = 0.901, p < 0.001, Fig. S2A) in single-cell RNA-seq data, and found that BGN was expressed in fibroblasts of normal tissues, and when cancer occurred, it was mainly expressed in tumor cells (Fig. S2B). The gene discussed is AEBP1; the disease is neoplasm.
