The role of 5-HT and its receptors in cisplatin-induced anorexia was investigated in four studies [45,46,47,48]; inflammatory cytokines [43,44,47,49] and WBCs [44,47,49,50] were also studied in four studies each; the roles of ghrelin and leptin in cisplatin-induced anorexia were assessed in five [43,44,45,46,48] and two [43,44] studies, respectively. Here, LEP is linked to Anorexia.
