Tissue localization in tumorigenesis is also highlighted, with patient-derived TCGA microarray data profiled across 31 cancer cohorts to provide a comprehensive guide to the relevance of NOX4/DUOX1/DUOX2 in cancer studies.
Therefore, an MTT assay, wound‑healing assay, quantitative polymerase chain reaction and western blotting assays were used to analyze the RAGE‑NOX‑4 pathway and to determine its potential involvement in glycometabolism‑associated tumorigenesis.
Thus, our results demonstrate the presence of an antagonistic relationship between tuberin and Nox4 to drive oncogenesis in the tuberin deficiency syndrome and identify Nox4 as a target to develop a therapy for TSC.
NADPH oxidase 4 (NOX4), a major source of reactive oxygen species (ROS) production, has been increasingly reported to be involved in tumorigenesis and/or tumor progression, but limited data are available regarding the role of NOX4 in colorectal carcinoma (CRC).
Our results offer direct evidence that NOX4 is critical for renal tumorigenesis and they show how NOX4 suppression and VHL re-expression in VHL-deficient RCC cells are genetically synonymous, supporting development of therapeutic regimens aimed at NOX4 blockade.
Interestingly, immunochemical analyses of NOX4 expression in human liver tumor cell lines and tissues revealed decreased NOX4 protein levels in liver tumorigenesis.
The results provide the first evidence for a role of Nox1, Nox4 and NFκB in PhIP-induced colon carcinogenesis, including during the early stages before tumor onset.
NADPH oxidase DUOX1, DUOX2, and NOX4 have recently been gained considerable concerns, owing to the fact that they involve in reactive oxygen species-induced genetic and epigenetic alternations of human carcinogenesis and serve as biomarkers in several cancers.
