Infection of this porcine epithelial cell line was demonstrated by upregulation of proteasome subunits PSMA1, PSMA2, PSMA5, PSMC5, and PSMD12, as well as other molecules such as CLTA, BSG, IDH1, KPNB1, MAP4, PCBP2, PGM1, RPL10A, RPL12, SF3A1, SF3B2, SNRPD3, TAGLN2, and TFRC (Table S1). The gene discussed is PSMA2; the disease is infection.
