Gamma-enolase enzymatic activity is involved in glycolysis, a prevalent process cancer cell metabolism. Additionally, gamma-enolase has pro-survival function, exhibited through the active site at C-terminal end of molecule. This regulated by cysteine peptidase cathepsin X, which cleaves two amino acids gamma-enolase. In clinical practice, determination as tumour marker does not differ between t...

In this study, two enolase genes were isolated and characterized from the Chinese oak silkworm, Antheraea perny, which were designated as enolase I and II, respectively. The enolase I cDNA sequence was 1712 bp with an open reading frame (ORF) of 1302 bp encoding 433 amino acids. The enolase II cDNA sequence was 1549 bp with an ORF of 1296 bp encoding 431 amino acids. The amino acid sequences of...

We have investigated the intracellular distribution and mobility of the glycolytic enzyme enolase, using functional fluorescent analogs labeled with the succinimidyl esters of carboxyfluorescein (F1-enolase) and carboxytetramethylrhodamine (Rh-enolase) In contrast to aldolase, neither native enolase nor labeled enolase gelled filamentous actin (F-actin), as measured by falling-ball viscometry, ...

Background: Alpha-enolase is an important glycolytic enzyme, and its aberrant expression has been associated with multiple tumor progression. However, few studies investigated the expression of alpha-enolase and its clinical significance in pancreatic cancer (PC). Objectives: To evaluate alpha-enolase level in PC tissues by immunohistochemical (IHC) analysis, and investigate the association of ...

In previous research, we found α-enolase to be inversely correlated with progression-free and overall survival in lung cancer patients and detected α-enolase on the surface of lung cancer cells. Based on these findings, we hypothesized that surface α-enolase has a significant role in cancer metastasis and tested this hypothesis in the current study. We found that α-enolase was co-immunoprecipit...

Enolase – a glycolytic enzyme is also expressed on the surface of eukaryotic cells such as macrophages, neutrophils, endothelial, neuronal, tumor cells. Surface enolase as plasminogen receptor plays an important role in myogenesis, tumorgenesis and angiogenesis. Determination of enolase localization in the cell lines may give rise to the elucidation of its receptor function in tumor cells. The ...

The enzyme enolase [EC 4.2.1.11] is found in all organisms, with vertebrates exhibiting tissue-specific isozymes encoded by three genes: alpha (alpha), beta (beta), and gamma (gamma) enolase. Limited taxonomic sampling of enolase has obscured the timing of gene duplication events. To help clarify the evolutionary history of the gene family, cDNAs were sequenced from six taxa representing major ...

Enolase detected on the cell surface may be a receptor for certain ligands, especially for plasminogen. It is important for the pathogen invasiveness and in the development of a tumour. Therefore, we sought to preliminarily determine the enolase location and catalytic activity in the subfractions of MCF-7 cells. The latter was done on intact cells and in subfractions of MCF-7 cells. We identifi...

A DNA clone containing a putative enolase gene was isolated from a genomic DNA library of the anaerobic fungus Neocallimastix frontalis. It was deduced from sequence comparisons that the enolase gene was interrupted by a large 331 bp intron. The enolase gene, termed enol, has an ORF of 1308 bp and encodes a predicted 436 amino acid protein. The deduced amino acid sequence shows high identity (7...

Myc-binding protein-1 (MBP-1) is a 37-kDa protein with sequence homology to the 3* portion of the a-enolase gene. a-Enolase is a 48-kDa protein, which plays a critical role in the glycolytic pathway. MBP-1 binds to the c-myc P2 promoter and down-regulates c-myc expression. We have investigated the role of a-enolase in regulation of the c-myc protooncogene. RNase protection assay shows that a-en...
