Carcinoma cells hijack the epithelial-mesenchymal transition (EMT) for tumor dissemination. Paired-related homeobox 1 (PRRX1) has been identified as a new EMT inducer. However, the function of PRRX1 in gastric cancer has not been elucidated. In this study, we observed that PRRX1 expression levels were upregulated and positively correlated with metastasis(More)
Peroxiredoxin 2 (Prdx2) has been shown to act as an antioxidant whose main function is to reduce hydrogen peroxide (H2O2) in cells, and Prdx2 is abnormally elevated in colorectal cancer (CRC). However, the functional significance of this up-regulation and the detailed molecular mechanism behind the regulatory effect of Prdx2 on the growth of CRC cells have(More)
Peroxiredoxin 2 (Prdx2) is a member of the peroxiredoxin family, which is responsible for neutralizing reactive oxygen species. Prdx2 has been found to be elevated in several human cancer cells and tissues, including colorectal cancer (CRC), and it influences diverse cellular processes involving cells’ survival, proliferation, and apoptosis, which suggests(More)
Hypoxia microenvironment, as a major feature of solid tumors, increases tumors progression and metastasis. To research whether hypoxia influences the epithelial-mesenchymal transition (EMT) and cancer stem cells (CSCs) of gastric cancer cells and their cell biological behaviors. Human gastric cancer cell lines BGC823 and SGC7901 were cultivated in different(More)
Although human peroxiredoxin 2 (PRDX2) has been implicated in tumor progression (e.g., invasion and metastasis), little is known regarding its role in the epithelial‑mesenchymal transition (EMT) process during tumorigenesis. The present study offers the first evidence, to the best of our knowledge, that the antioxidant enzyme PRDX2 has an important role in(More)
The mammalian peroxiredoxin 2 (Prdx2) is a member of thiol-dependent antioxidant proteins and plays an important role in the progression of colorectal cancer (CRC). The aim of this study was to confirm the role of Prdx2 in formation of VM and progression of CRC. Immunohistochemistry and CD34/periodic acid Schiff double staining were performed to explore the(More)
Cancer stem cells (CSCs) are a key target for reducing tumor growth, metastasis, and recurrence. Redox status is a critical factor in the maintenance of CSCs, and the antioxidant enzyme Peroxiredoxin 2 (Prdx2) plays an important role in the development of colon cancer. Therefore, we investigated the contribution of Prdx2 to the maintenance of stemness of(More)
