Immunoblot analysis of hypothalamic lysates with a phospho-specific STAT3 antibody showed a 6- to 7-fold stimulation of STAT3 tyrosine phosphorylation in response to both leptin and TNFalpha.

Leptin induced phosphorylation of Janus kinase (JAK)2, signal transducer and activator of transcription (STAT)3, and extracellular signal-regulated kinase (ERK) in ECs from ZL rats but not ZF rats.

The transcription factor Stat3 is activated by multiple cytokines, including leptin and those signaling through the gp130 receptor.

|
Leptin stimulation led to janus kinase (JAK)2-dependent phosphorylation and nuclear translocation of the transcription factors signal transducer and activator of transcription (STAT)3 and STAT5b in INS-1 beta-cells.

|
Leptin activates Janus-activating kinase2 (Jak2) and STAT 3, resulting in stimulation of anorexigenic peptides, e.g., alpha-MSH and CART, and inhibition of orexigenic peptides, e.g., NPY and AGRP.

In order to understand leptin action we have explored the physiological function of LRb signalling pathways, defining important roles for signal transducer and activator of transcription-3 (STAT3) in positive signalling and for LRbTyr(985)-mediated feedback inhibition in leptin signal attenuation.

Leptin receptors in the hypothalamus are known to signal via distinct mechanisms, including signal transducer and activator of transcription-3 (STAT3) and phosphoinositol-3 kinase (PI 3-kinase).

|
Leptin and amylin alone and in combination activate signal transducer and activator of transcription 3 (STAT3), AMP-activated protein kinase, Akt, and extracellular signal-regulated kinase signaling pathways in hAT ex vivo and hPAs and hPBMCs in vitro; all phosphorylation events were saturable at leptin and amylin concentrations of ?50 and ?20 ng/ml, respectively.

|
The effects of leptin and amylin on STAT3 phosphorylation in hPAs and hPBMCs in vitro were totally abolished under endoplasmic reticulum stress and/or in the presence of a STAT3 inhibitor.

Moreover, leptin directly activated the STAT3 signaling pathway and downregulated FTO in in vitro arcuate nucleus of hypothalamus cultures and in vivo wild-type mice but not db/db mice.

|
Leptin binding to its receptor triggers multiple signaling pathways, including signal transducer and activator of transcription 3 (Stat 3), phosphatidylinositol-3-kinase, and ERK.

In vitro, Q223R did not affect leptin signaling as reflected by activation of STAT3.
