Seven DNA Methylation Biomarker Prediction Models for Monitoring the Malignant Progression From Advanced Adenoma to Colorectal Cancer.

Advanced adenoma (AA) holds a significantly increased risk for progression to colorectal cancer (CRC), and we developed a noninvasive DNA methylation prediction model to monitor the risk of AA progression to CRC. We analyzed the differential methylation markers between 53 normal mucosa and 138 CRC tissues, as well as those in cfDNA (cell-free DNA) between 59 AA and 68 early-stage CRC patients. We screened the overlapping markers between tissue DNA and cfDNA for model variables and optimized the selected variables.

Expressions of EZH2 and NOTCH3 pathway in osteosarcoma and their roles in osteosarcoma stem cells.

Osteosarcoma (OS) is the most common malignant bone tumour; however, the underlying mechanisms are mainly unknown. Enhancer of zeste homologue 2 (EZH2) and NOTCH pathway are important molecular signals related to carcinogenesis and tumour progression, but they are not fully understand in OS. Enhancer of zeste homologue 2, Notch3, HES1, and Nanog were detected on OS samples and statistically analysed.

Mir-20a-5p induced WTX deficiency promotes gastric cancer progressions through regulating PI3K/AKT signaling pathway.

Background: The X-linked gene WTX (also called AMER1) has been reported to function as a tumour suppressor gene in Wilms' tumour. In our previous study, WTX expression was shown to be significantly reduced in gastric cancer (GC), but the function and mechanism associated with WTX loss had yet to be fully elucidated.

Methods: WTX expression and clinical significance were father analyzed in GC and control normal gastric tissues, and validated in public databases.

Mir20a/106a-WTX axis regulates RhoGDIa/CDC42 signaling and colon cancer progression.

Wilms tumor gene on the X chromosome (WTX) is a putative tumor suppressor gene in Wilms tumor, but its expression and functions in other tumors are unclear. Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in women and the second leading cause in men in the United States. We demonstrated that WTX frequently lost in CRC which was highly correlated with cell proliferation, tumor invasion and metastasis.

WTX inhibits gastric cancer migration through the reversal of epithelial-mesenchymal transition.

The aim of the present study was to investigate whether the expression of Wilms' tumor gene on X chromosome (WTX) affected the epithelial-mesenchymal transition (EMT) process and migration of gastric cancer cells. Stable WTX-overexpressing AGS cells (AGS.W) were established and analyzed by flow cytometry.

Resveratrol reverses Doxorubicin resistance by inhibiting epithelial-mesenchymal transition (EMT) through modulating PTEN/Akt signaling pathway in gastric cancer.

Background: Gastric cancer is one of the major causes of cancer-related mortality worldwide. Most of patients presenting with inoperable gastric cancers rely on systemic chemotherapy for prolongation of survival. Doxorubicin (DOX) is one of the important agents against gastric cancer.
