BACKGROUND Most normal cells in the presence of oxygen utilize glucose for mitochondrial oxidative phosphorylation. In contrast, many cancer cells rapidly convert glucose to lactate in the cytosol, a process termed aerobic glycolysis. This glycolytic phenotype is enabled by lactate dehydrogenase (LDH), which catalyzes the inter-conversion of pyruvate and lactate. The purpose of this study was t...
Reprogramming of cellular energy metabolism is widely accepted to be one of the main hallmarks of cancer. The aberrant expression pattern of key regulators in the glycolysis pathway in cancer cells corroborates with the hypothesis that most cancer cells utilize aerobic glycolysis as their main ATP production method instead of mitochondrial oxidative phosphorylation. Overexpression of SLC2A1 and...
Metabolic reprogramming is a hallmark of cancer. Elevated glycolysis in cancer cells switches the cellular metabolic flux to produce more biological building blocks, thereby sustaining rapid proliferation. Recently, new evidence has emerged that metabolic dysregulation may occur at early-stages of neoplasia and critically contribute to cancer initiation. Here, our bioinformatics analysis of mic...
Rhizopus oryzae is used for industrial production of lactic acid, yet little is known about the genetics of this fungus. In this study I cloned two genes, ldhA and ldhB, which code for NAD(+)-dependent L-lactate dehydrogenases (LDH) (EC 1.1.1.27), from a lactic acid-producing strain of R. oryzae. These genes are similar to each other and exhibit more than 90% nucleotide sequence identity and th...
There are over 120 types of brain tumor and approximately 45% of primary brain tumors are gliomas, of which glioblastoma multiforme (GBM) is the most common and aggressive with a median survival rate of 14 months. Despite progress in our knowledge, current therapies are unable to effectively combat primary brain tumors and patient survival remains poor. Tumor metabolism is important to consider...
Abstract Background Lactate dehydrogenase A ( LDHA) is overexpressed and associated with poor prognosis in many kinds of cancer. In the current study, we evaluated prognostic value LDHA expression non-small cell lung cancer (NSCLC), tested whether inhibition might improve radiotherapy efficacy NSCLC. Methods was investigated NSCLC patients, using online database further verified by immunohistoc...
Background: It is expected that the expression of key enzymes glycolysis pathway, specially PFK-1, increases tumor cells and so enhances function this pathway. The p53 HIF-1 proteins are regulators PFK-1 LDH enzymes. This study was performed to investigate changes in LDH-A, p53, HIF-1α genes identify metabolic non-small cell lung carcinoma (NSCLC) samples. Methods: A number 30 tumors their adja...
Targeting the specific metabolic phenotypes of colorectal cancer stem cells (CRCSCs) is an innovative therapeutic strategy for colorectal cancer (CRC) patients with poor prognosis and relapse. However, the context-dependent metabolic traits of CRCSCs remain poorly elucidated. Here we report that adenylate kinase hCINAP is overexpressed in CRC tissues. Depletion of hCINAP inhibits invasion, self...
Although hexokinase (HK) 2, pyruvate kinase muscle (PKM) isozyme 2 and lactate dehydrogenase (LDH) A predict the efficacy of medicines in various solid tumors, their ability to predict the efficacy of cetuximab in metastatic colorectal cancer (mCRC) remains unclear. mCRC patients with pathological specimens who received cetuximab and chemotherapy from 2005 to 2015 in the present institution wer...
Type II diabetes mellitus (T2D) is a chronic metabolic disorder that results from defects in both insulin secretion and insulin action. The deficit and dysfunction of insulin secreting β-cell are signature symptom for T2D. Additionally, in pancreatic β-cell, a small group of genes which are abundantly expressed in most other tissues are highly selectively repressed. Lactate dehydrogenase A (LDH...
