OBJECTIVES To explore the correlation between expression patterns and functions of miR-383 and LDHA in hepatocellular cancer (HCC). MATERIALS AND METHODS We detected the expression of miR-383 and LDHA in 30 HCC tissues and their matched adjacent normal tissues using qRT-PCR. Then we performed MTT assay, foci formation assay, transwell migration assay, glucose uptake assay and lactate producti...

The transcription factor c-Myc plays critical roles in cancer development and progression through regulating expression of targeted genes. Lactate dehydrogenase A (LDHA), which catalyzes the conversion of L-lactate to pyruvate in the final step of anaerobic glycolysis, is frequently upregulated in pancreatic cancer. However, little is known about the effects of c-Myc-LDHA axis in the progressio...

Lactate dehydrogenase A (LDHA) is involved in a variety of cancers. The purpose of this study was to investigate the expression, prognostic roles and function of LDHA in breast cancer. We found that LDHA was upregulated in both breast cancer cell lines and clinical specimens using quantitative real-time PCR (qRT-PCR). Immunohistochemistry (IHC) analysis of tissue microarrays (TMAs) showed that ...

Lactate dehydrogenase A (LDHA) is an important enzyme in fermentative glycolysis, generating most energy for cancer cells that rely on anaerobic respiration even under normal oxygen concentrations. This renders LDHA a promising molecular target for the treatment of various cancers. Several efforts have been made recently to develop LDHA inhibitors with nanomolar inhibition and cellular activity...

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 ...

The diarrheal potential of a Bacillus cereus strain is essentially dictated by the amount of secreted nonhemolytic enterotoxin (Nhe). Expression of genes encoding Nhe is regulated by several factors, including the metabolic state of the cells. To identify metabolic sensors that could promote communication between central metabolism and nhe expression, we compared four strains of the B. cereus g...

Pulmonary fibrosis is a common and dose-limiting side-effect of ionizing radiation used to treat cancers of the thoracic region. Few effective therapies are available for this disease. Pulmonary fibrosis is characterized by an accumulation of myofibroblasts and excess deposition of extracellular matrix proteins. Although prior studies have reported that ionizing radiation induces fibroblast to ...

BACKGROUND Mutations of the isocitrate dehydrogenase 1 and 2 gene (IDH1/2) were initially thought to enhance cancer cell survival and proliferation by promoting the Warburg effect. However, recent experimental data have shown that production of 2-hydroxyglutarate by IDH mutant cells promotes hypoxia-inducible factor (HIF)1α degradation and, by doing so, may have unexpected metabolic effects. ...

Pancreatic cancer has a 5-year survival rate of less than 4%. Despite advances in diagnostic technology, pancreatic cancer continues to be diagnosed at a late and incurable stage. Accurate biomarkers for early diagnosis and to predict treatment response are urgently needed. Since alteration of glucose metabolism is one of the hallmarks of cancer cells, we proposed that pyruvate kinase type M2 (...

As the result of genetic alterations and tumor hypoxia, many cancer cells avidly take up glucose and generate lactate through lactate dehydrogenase A (LDHA), which is encoded by a target gene of c-Myc and hypoxia-inducible factor (HIF-1). Previous studies with reduction of LDHA expression indicate that LDHA is involved in tumor initiation, but its role in tumor maintenance and progression has n...
