Chemerin system expression in the porcine stalk median eminence (SME) during the oestrous cycle. Gene and protein expression of chemokine-like receptor 1 (CMKLR1; A and B), G protein-coupled receptor 1 (GPR1; C and D) and C-C motif chemokine receptor-like 2 (CCRL2; E and F), as well as chemerin (RARRES2) mRNA content (G) in the porcine SME on days: 2 to 3, 10 to 12, 14 to 16 and 17 to 19 of the oestrous cycle. Gene expression was determined by qPCR. Protein expression was determined by Western blotting; upper panels: representative immunoblots; lower panels: densitometric analysis of CMKLR1/GPR1/CCRL2 proteins relative to actin protein. Representative actin blots are identical for all chemerin receptors though proteins have been analysed on different gels. Results are presented as means ± SEM (n = 5). Bars with different superscripts differ (one-way ANOVA at p < 0.05 followed by Tuckey post-hoc test at p < 0.05).
