The fractions of the different chemerin forms found in ovarian carcinoma ascitic samples with a low proportion of intact precursor chem163S plus high levels of active chemerin, chem157S and chem156F, differ from those in circulation irrespective of whether they were plasma or serum and if they were from participants with BMI < 25 or patients with BMI > 40 (Figure 1) in the low proportion of intact precursor chem163S. Here, RARRES2 is linked to ovarian carcinoma.
