26892607 Results show that PA28alpha was found to be overexpressed in oral squamous cell carcinoma cell lines and tumor tissues. High expression of PA28alpha was significantly associated with recurrence and poorer overall survival.
26399368 Constitutive expression of PA28 and ERAP1 in melanoma cells indicate that both interfere with MART-1(26-35) epitope generation even in the absence of IFN-gamma
23918357 PA28 is a tumor marker and a potential target for therapeutic intervention in prostate cancer.
23383295 Reduction in ATP levels triggers immunoproteasome activation by the 11S (PA28) regulator during early antiviral response mediated by IFNbeta in mouse pancreatic beta-cells.
22532226 the first evidence of a novel ovarian cancer-specific marker
19403671 HIV-1 CA downregulates PA28beta and the beta2i subunit of the immunoproteasome complex in a dendritic cell line (JAWS II), whereas in primary dendritic cells, PA28alpha, beta2i, and beta5i are downregulated by CA
19225532 bortezomib-adapted HL-60 cells showed increased expression and proteasome association of the 11S proteasome activator
17939699 the 11S proteasome activator complex, Reg alpha fragment, may have a role in ovarian cancer
17671684 DJ-1 and PA28alpha may have roles in the onset of hepatocarcinogenesis
14760793 The relationship between anti-PA28alpha and Ki antibodies suggests the importance of an antigen-driven system in the induction of an autoimmune response to PA28 complex.
