On the DL-P vs. H comparison, which evaluated the effect of the dyslipidemia and periodontitis, the qPCR confirmed that the HLADRB4 and CD47 (CD47 molecule) genes were upregulated in H, while the DAB2 (DAB adaptor protein 2) gene was downregulated in H (Fig. 6A,D). The gene discussed is DAB2; the disease is periodontitis.
