Furthermore, the correlation between cancer and the potential rise in chemerin levels due to obesity remains unclear, necessitating further research to elucidate this relationship and its implications for cancer progression and treatment [62,63] Conversely, investigating the relationship between chemerin levels and cachexia could uncover mechanisms by which chemerin influences muscle wasting and weight loss, which represent common complications in advanced cancer stages [58]. The gene discussed is RARRES2; the disease is obesity due to melanocortin 4 receptor deficiency.
