    R&D Systems leptin receptor ob r antibody
    <t>Leptin</t> receptor (Ob-R) antagonist reduced the number of metastatic lung nodules and the diameter of nodules. (A) Procedure of animal experiment. Nude mice received venous transplantation of TPC-1 cells. To block OB-R, 1 mg/kg of Allo-aca was administrated to the animal per day. (B) Gross morphology of mice lungs showed nodules. Allo-aca reduced the number of pulmonary nodules. (C) Lung nodules were diagnosed as metastatic tumour under the light microscope. Allo-aca reduced the diameter of the nodules. (D) The lung nodules were examined by Western blot of thyroglobulin (TG). The nodules in the lungs were TG -positive, while the lung tissue was TG -negative. This result confirmed that the lung nodules were from thyroid carcinoma. (E–H) Allo-aca increased the level of serum T3, and had no significant effect on the level of T4, TSH and the body weight of the animal. Experiments were repeated at least five times. Data are expressed as mean ± standard deviation. * p < 0.05, *** p < 0.001, ns: not statistically significant.

    The conditioned medium of ADSCs upregulated the level of leptin receptor (Ob-R) in TPC-1 and BCPAP cells. (A) The concentration of leptin in the medium of ADSCs was ∼3-fold higher than that in the medium of TPC-1 and BCPAP cells, approximately 50 pg/ml. (B) In vitro experiments showed that ADSC-CM increased the level of leptin receptor (Ob-R) in the TPC-1/BCPAP cells. Experiments were repeated at least five times.

    The neutralizing antibody to leptin reduced the invasion and migration of the TPC-1 and BCPAP cells. ADSC-CM upregulated MMP-2 in TPC-1 and BCPAP cells, and the effect was attenuated by the neutralizing antibody to leptin. (A) Addition of 10 μg/mL NAB of leptin to ADSC-CM conditioned medium attenuated TPC-1 and BCPAP invasion. (B) Leptin NAB also attenuated conditioned medium-promoted TPC-1/BCPAP migration. Experiments were repeated at least five times. Data are expressed as mean ± standard deviation. * p < 0.05, *** p < 0.001.

    Hypothesis diagram. Adipose tissue acts on thyroid cancer cells by secreting leptin. Leptin upregulates the level of the leptin receptor (Ob-R) on the surface of thyroid cancer cells and up-modulates the level of MMP-2 by activating the leptin signalling pathway, which may be an important mechanism by which obesity promotes the metastasis of thyroid cancer cells.

    The neutralizing antibody to leptin reduced the invasion and migration of the TPC-1 and BCPAP cells. ADSC-CM upregulated MMP-2 in TPC-1 and BCPAP cells, and the effect was attenuated by the neutralizing antibody to leptin. (A) Addition of 10 μg/mL NAB of leptin to ADSC-CM conditioned medium attenuated TPC-1 and BCPAP invasion. (B) Leptin NAB also attenuated conditioned medium-promoted TPC-1/BCPAP migration. Experiments were repeated at least five times. Data are expressed as mean ± standard deviation. * p < 0.05, *** p < 0.001.

    Neutralizing antibodies against leptin slightly downregulated cell proliferation without significant effect on cell viability. (A) Addition of leptin NAB to ADSC-CM slightly reduced the stimulatory effect of conditioned medium on TPC-1 proliferation. (B) Addition of NAB to the conditioned medium had no significant effect on cell viability of TPC-1 cells. (C) NAB of leptin had no significant effect on BCPAP proliferation. (D) NAB of leptin had no significant effect on BCPAP viability. Experiments were repeated at least five times. Data are expressed as mean ± standard deviation. * p < 0.05, ns: not statistically significant.

    Hypothesis diagram. Adipose tissue acts on thyroid cancer cells by secreting leptin. Leptin upregulates the level of the leptin receptor (Ob-R) on the surface of thyroid cancer cells and up-modulates the level of MMP-2 by activating the leptin signalling pathway, which may be an important mechanism by which obesity promotes the metastasis of thyroid cancer cells.
