Abstract
Lactate dehydrogenase (LDHA) activation induces tumorigenesis by activating tumor proliferation, growth, invasion, and metastasis. Whether LDHA mediates tumor metabolism that upon diffuse large B-cell lymphoma (DLBCL) occur remains unknown. Here, we investigated how LDHA adopt tumor metabolism after activation to regulate DLBCL-inducible. We investigated LDHA is highly expressed in peripheral blood mononuclear cells (PBMCs) of DLBCL patients. Knockdown of LDHA results in an increase in the apoptosis of cells, suppression of cell growth and migration in OCI-Ly1 and OCI-Ly10 cells. We show that LDHA gains a canonical enzyme activity to produce lactate and triggers NAD + in DLBCL cells. Furthermore, p-STAT5 was identified as a downstream target of LDHA, and the p-STAT5 protein level was significantly reduced related to decreased LDHA protein expression. Collectively, our findings identify the oncogenic role of LDHA in DLBCL and suggest that LDHA can be considered as a pivotal prognostic biomarker and a potential therapeutic target.
期刊介绍：
Annals of Hematology covers the whole spectrum of clinical and experimental hematology, hemostaseology, blood transfusion, and related aspects of medical oncology, including diagnosis and treatment of leukemias, lymphatic neoplasias and solid tumors, and transplantation of hematopoietic stem cells. Coverage includes general aspects of oncology, molecular biology and immunology as pertinent to problems of human blood disease. The journal is associated with the German Society for Hematology and Medical Oncology, and the Austrian Society for Hematology and Oncology.
