Figure 1B presents the correlation between these genes. As shown in Figure 1C, D, NLRP6, NLRC4, NLRP9 and other 13 DE-PRGs were upregulated in BPD group, while CHMP7, NLRP2, and other 4 DE-PRGs were downregulated, further confirming the results in Figure 1A. The gene discussed is NLRP2; the disease is bronchopulmonary dysplasia.
