Figure 4. PTPN2 inhibitor XIX mimics the effects of PTPN2 deletion in THP-1 cells. (A) Expression of PTPN2 in THP-1 cells with different concentration of XIX were detected by IB assay. (B) mRNA levels of IL-12 and IL-1β in THP-1 cells were analyzed by qRT-PCR assay. (C) ELISA assay was used to analyze the production of IL-12 and IL-1β in THP-1 cells in the presence of XIX or ox-LDL. (D) Indicated proteins in THP-1 cells were detected by IB assay. (E, F) Transwell migration and invasion assays were performed in THP-1 cells. Bar= 20μM. (G) MTT assay was used to analyze the viability of HUVEC cell after incubated with THP-1 cells. Data are representative of at least three independent experiments and are presented as mean ± SD. ns, not statistically significant; *, P < 0.05. **, P < 0.01.
