Abstract

T‑cell lymphoma (TCL) is a group of heterogeneous disorders with a poor response to conventional treatment. In order to identify novel therapeutic targets, the present study investigated the effect of leptin and its receptor on glucose metabolism in TCL. The expression of the leptin receptor (ObR), and glucose transporter (Glut)1 and 4 was detected in TCL and reactive lymphoid hyperplasia (RLH) tissues by immunohistochemical analysis. A higher level of ObR expression was observed in the TCL tissues than in the RLH tissues (58.3 vs. 22.2%; P=0.012), and ObR overexpression was associated with high expression of Glut1 (P=0.007). In vitro analysis using the human TCL MOLT‑3 cell line demonstrated that leptin stimulated cell glucose uptake via promoting recruitment and expression of Glut1, effects which were abolished by ObR‑specific small interfering RNA (siRNA). Additionally, MOLT‑3 cell viability was also increased following leptin treatment. ObR‑specific siRNA abolished these responses. In conclusion, these results suggested that leptin serves a critical role in TCL glucose uptake via the ObR.
