The activity of isocitrate dehydrogenase (ICDH) was studied in the tissue of breast cancer and in the blood serum of the women suffering from this neoplasm. The comparative material was the physiological tissue of mammae and blood serum of the healthy women. The activity of ICDH in neoplasm tissue
Lymphovascular invasion (LVI) is a prerequisite step in breast cancer (BC) metastasis. We have previously identified wild-type isocitrate dehydrogenase 2 (IDH2) as a key putative driver of LVI. Thus, we explored the prognostic significance of IDH2 at transcriptome and protein Somatic mutations of isocitrate dehydrogenase (IDH)-1 and IDH2 proteins have been described in gliomas. The mutations target the R132 amino acid residue and the R172 residue in IDH1 and IDH2, respectively. The same mutations were observed in acute myeloid leukemias with normal karyotype, but a new
The isocitrate dehydrogenase (IDH) gene family expresses key functional metabolic enzymes in the Krebs cycle and mediates the epigenetic reprogramming, which serves as an important biomarker of breast cancer. However, the expression levels of the IDH protein and their biological function in human
Distant metastasis represents the major lethal cause of breast cancer. To understand the molecular mechanisms of breast cancer metastasis and identify markers with metastatic potential, we established a highly metastatic variant of parental MDA-MB-231 cells (MDA-MB-231HM). Using two-dimensional
A recent research of cancer has indicated that the mutant of isocitrate dehydrogenase 1 and 2 (IDH1 and 2) genes will induce various cancers, including chondrosarcoma, cholangiocarcinomas, and acute myelogenous leukemia due to the effect of point mutations in the active-site arginine residues of
A binary logistic model is used for predicting response to cytotoxic chemotherapy for a breast cancer patient on the basis of her tumor enzyme activity profile. The enzymes used in the model are lactate dehydrogenase, nicotinamide adenine dinucleotide phosphate-isocitrate dehydrogenase, and
We aimed to investigate the influence of radiation on hypoxia-treated breast cancers cells and its underlying mechanism. We mimicked the hypoxic response in MCF-7 cells by the treatment of CoCl2. Meanwhile, hypoxic MCF-7 cells induced by CoCl2 or untreated MCF-7 cells were treated with or without
BACKGROUND
Breast cancer represents a major public health problem in women worldwide. For many cancers, serum tumour markers play an important role in patient treatment and monitoring. Isocitrate dehydrogenase enzyme is also used as a biomarker for various types of cancer.
OBJECTIVE
The purpose of
Mammary tumors are a major health threat to women and female dogs. In both, metastasis of the primary tumor to distant organs is the most common cause of tumor-related death. Nevertheless, the molecular mechanisms of tumor metastasis are far from being understood, and it is still unknown why some
Activities of glucosephosphate isomerase, lactate dehydrogenase, and NADP-isocitrate dehydrogenase were significantly elevated in breast cancer specimens from patients who responded favorably to combination cytotoxic chemotherapy regimens compared with those in carcinomas from patients failing to
The oncometabolite, D-2-hydroxyglutarate, accumulates in various cancers because of acquired mutations in isocitrate dehydrogenase 1 & 2. Here, we describe a new mechanism for D-2-hydroxyglutarate accumulation in breast cancer. It involves c-Myc signaling and alcohol dehydrogenase, iron-containing
BACKGROUND
Cancer cells have an abnormal energetic metabolism. One of the earliest discovered hallmarks of cancer had its roots in bioenergetics, as many tumours were found in the 1920s to exhibit a high glycolytic phenotype. An animal with cancer shows significant and progressive energy loss from
Mass spectrometry and nuclear magnetic resonance-based metabolomics have been developed into mature technologies that can be utilized to analyze hundreds of biological samples in a high-throughput manner. Over the past few years, both technologies were utilized to analyze large cohorts of fresh
Chemoresistance is a poor prognostic factor in breast cancer and is a major obstacle to the successful treatment of patients receiving chemotherapy. However, the precise mechanism of resistance remains unclear. In this study, a pair of breast cancer cell lines, MCF-7 and its adriamycin-resistant
