Increased IL-1β, PTX-3 and PROKR2 mRNA and protein levels in mice lacking Mmp8. (a) IL-1β, pentraxin-3 (PTX-3) and prokineticin receptor 2 (PROKR2) mRNA levels were measured by quantitative real-time PCR in arthritic joints of Mmp8-/- mice (n = 6) and Mmp8+/+ mice (n = 6) at day 7 after intraperitoneal serum injection. Levels of IL-1β (b) and PTX-3 (c) proteins were measured by ELISA in extracts from arthritic joints of mice at day 7 after intraperitoneal serum injection. Values expressed as mean ± standard error of the mean; *P < 0.05, by two-sided Mann-Whitney U test.
