目的：探讨瘦素对巨核细胞白血病的影响。方法以急性巨核细胞白血病细胞株M07藻为研究对象。运用砸栽-孕悦砸检测M07藻细胞瘦素受体皂砸晕A表达，运用月则凿怎-耘蕴陨杂A法检测瘦素对M07藻细胞的增殖作用，运用A灶灶藻曾蚤灶灾/孕陨双标流式检测瘦素对M07藻细胞的凋亡作用。结果瘦素受体长型韵遭-砸蕴和短型韵遭-砸杂在M07藻细胞均有皂砸晕A表达。瘦素对M07藻细胞的增殖有促进作用，并呈现一定的剂量依赖性，浓度为5灶早/皂L即显示出促增殖效应(孕越0.037)，但浓度在5、10、25灶早/皂蕴之间无明显统计学差异，浓度为100灶早/皂蕴时其增殖效应最大。在时间依赖效应上，瘦素作用48澡，其细胞增殖明显高于作用24澡，而作用72澡其细胞增殖介于两者之间(孕越0.000)。瘦素对M07藻细胞具有抑制凋亡作用(孕越0.001)，而且在作用72h后凋亡率最高。结论瘦素通过促进M07藻细胞的增殖，抑制其凋亡来参与巨核细胞白血病的发生、发展。

Objective To explore whether leptin plays a role in megakaryocytic leukemia. Methods Megakaryocytic leukemia cell line M07e was used in this study. The mRNA expression of leptin receptor (Ob-R) in M07e was detected by RT-PCR. The proliferative effect of leptin on cell M07e was investigated with Brdu-ELISA and the apoptosis of cells was measured with flow cytometry after Annexin V labeling and PI staining. Results There was mRNA expression of Ob-RL and Ob-RS in M07e. Leptin promoted the proliferation of M07e in a dose and time dependent manner. The effect of proliferation was the most significant at the concentration of 100 ng/mL and after cultured for 48 hours. Leptin inhibited the apoptosis of M07e (P = 0.001), and the highest rate of apoptosis appeared after 72 hours. Conclusions Leptin may play an important role in human megakaryocytic leukemia by promoting the proliferation and inhibiting the apoptosis of M07e.
