Abstract: Leptin is a multifunctional adipose-derived cytokines that play a critical role in bodyweight homeostasis and energy balance.  
Recently, leptin and leptin receptor dysreulation  have been reported in variety of malignant cells including thyroid.  Leptin modulates growth
and proliferation of cancer cells via activation of various growth and survival signaling pathways  including JAK/STAT, PI3-kinase/AKT and/or
Map kinases. In this review, current understanding of leptin’s role in the pathogenesis of thyroid cancer has been described. (IJCEP1108015).

Keywords: Leptin, leptin receptors, sinaling pathways, papillary thyroid carcinoma
