RESUMEN

The oncogenic transcription factor forkhead box protein M1 (FOXM1) plays critical roles in gastric cancer (GC) development and progression. However, the underlying mechanisms has not fully demonstrated. Lactate dehydrogenase A (LDHA) is widely overexpressed in a series of cancers and is one of the two subunits of Lactate dehydrogenase (LDH), which is the key glycolytic enzyme and catalyzes the interconversion of pyruvate and lactate. In this study, we characterized the regulation of aerobic glycolysis by FOXM1 via transactivation of LDHA in GC. We found that LDHA was overexpressed GC cells, and the expression of LDHA was transcriptionally regulated by FOXM1. Furthermore, FOXM1 regulated GC cells glycolytic phenotype, proliferation, migration and invasion via LDHA. Thus, FOXM1-LDHA signaling functioned as a stimulator of glycolysis and promoted GC progression.
