However, lipocalin 2 (LCN2), cyclin-dependent kinase 2 (CDK2), and cyclin A2 (CCNA2) were significantly upregulated, and tissue factor pathway inhibitor (TFPI), growth factor receptor-bound protein 2 (GRB2), and cyclin-dependent kinase inhibitor 1B (CDKN1B) were significantly downregulated in PSMA2 KD+PR8 infection but oppositely regulated and not significant in non-KD PR8-infected cells. Here, CDK2 is linked to infection.
