AI Article Synopsis
- CDCA7L, a member of the JPO protein family and a target gene of c-Myc, is often dysregulated in various cancers, and this study investigates its role and clinical significance in glioma.
- Analysis revealed that higher CDCA7L expression correlates with larger tumor size, higher WHO grade, recurrence, and worse overall and recurrence-free survival rates in glioma patients.
- Knocking down CDCA7L in glioma cells reduced their invasion capabilities, indicating that CDCA7L not only predicts poor prognosis but also contributes to glioma progression, potentially serving as a prognostic biomarker.
Article Abstract
Background: Cell division cycle associated 7 like (CDCA7L) belongs to the JPO protein family, which is recently identified as a target gene of c-Myc and is frequently dysregulated in multiple cancers. This study aimed to explore the clinicpathological value and biological role of CDCA7L in glioma.
Methods: CDCA7L expression in glioma patients was determined using the Oncomine database, and the prognostic role of CDCA7L expression was assessed in a retrospective cohort study. Moreover, the relationship of CDCA7L expression with the clinicopathological characteristics in glioma patients, including age, gender, tumor size, cystic change, Karnofsky performance scale (KPS) score, tumor location, extent of resection, WHO grade, adjuvant therapy and tumor recurrence, was analyzed in this study. In addition, the CDCA7L small interfering (si) RNA was constructed and transfected into the glioma U251 cells, so as to examine the role of CDCA7L in glioma patients. Besides, the changes in U251 cell invasion after transfection with CDCA7L siRNA were also monitored through Transwell assay.
Results: Our results suggested that CDCA7L expression was up-regulated in different glioma types, including glioblastoma, oligodendroglioma, diffuse astrocytoma and anaplastic astrocytoma. Moreover, the current retrospective cohort study indicated that high CDCA7L expression was associated with tumor size, WHO grade, adjuvant therapy and recurrence, as well as the poor overall survival (OS) and recurrence-free survival (RFS) in glioma patients. Lastly, CDCA7L expression was knocked down using CDCA7L siRNA, which could block the invasion abilities of glioma U251 cells.
Conclusions: CDCA7L is highly expressed in human glioma tissues and a high CDCA7L expression level predicts the dismal prognosis for glioma patients. Moreover, CDCA7L can promote glioma invasion, which can serve as an independent potential prognostic biomarker for glioma patients.
