Abstract
Ovarian cancer is the second most common cause of gynecological cancer death and has a high recurrence rate. FOXN3, a transcription inhibitor belonging to FOX family, has anti-tumor effects on several cancers. Bioinformatics analysis revealed that the expression of FOXN3 was downregulated in ovarian cancer specimens. However, the role of FOXN3 in ovarian cancer remains unclear. Herein, we investigated the role of FOXN3 in ovarian cancer using OVCAR3 and A2780 cells. Flow cytometry and CCK-8 analysis showed that overexpression of FOXN3 inhibited the proliferation and cell cycle progression of OVCAR3 cells. Cell invasion and migration abilities were decreased by FOXN3 according to transwell and wound healing assays. The suppression of FOXN3 on angiogenesis in OVCAR3 cells was evidenced by reduced vessel formation and VEGFA protein expression. Taken together, FOXN3 had an inhibitory effect on the proliferation, migration, invasion and angiogenesis of OVCAR3 cells, while its knockdown exhibited an opposite effect in A2780 cells. By inoculation of FOXN3-overexpressing cells into nude mice, tumorigenesis assay demonstrated that FOXN3 could delay the growth of ovarian cancer cells in vivo. The interaction between FOXN3 and RPS15A was preliminarily explored via dual-luciferases assay and ChIP. FOXN3 was confirmed to bind to the promoter (at - 1588/- 1581 and - 1476/- 1467) of gene RPS15A and inhibit its transcriptional expression. We further found that overexpression of RPS15A diminished the inhibition of FOXN3 on ovarian cancer cell malignant behaviors. These findings indicate that FOXN3 negatively regulates the expression of RPS15A and thus suppresses the progression of ovarian cancer.

DLK2 Acts as a Potential Prognostic Biomarker for Clear Cell Renal Cell Carcinoma Based on Bioinformatics Analysis. Genes (Basel) 2022; 13:genes13040629. [PMID: 35456435 PMCID: PMC9030291 DOI: 10.3390/genes13040629] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 03/26/2022] [Accepted: 03/28/2022] [Indexed: 02/07/2023] Open
Abstract
Clear cell renal cell carcinoma (ccRCC) is the most common RCC subtype with a high mortality. It has been reported that delta-like 1 homologue (DLK1) participates in the tumor microenvironmental remodeling of ccRCC, but the relationship between delta-like 2 homologue (DLK2, a DLK1 homologue) and ccRCC is still unclear. Thus, this study aims to investigate the role of DLK2 in the biological function and disease prognosis of ccRCC using bioinformatics analysis. The TNMplot database showed that DLK2 was upregulated in ccRCC tissues. From the UALCAN analysis, the overexpression of DLK2 was associated with advanced stage and high grade in ccRCC. Moreover, the Kaplan-Meier plotter (KM Plotter) database showed that DLK2 upregulation was associated with poor survival outcome in ccRCC. By the LinkedOmics analysis, DLK2 signaling may participated in the modulation of ccRCC extracellular matrix (ECM), cell metabolism, ribosome biogenesis, TGF-β signaling and Notch pathway. Besides, Tumor Immune Estimation Resource (TIMER) analysis showed that the macrophage and CD8+ T cell infiltrations were associated with good prognosis in ccRCC patients. Finally, DLK2 overexpression was associated with the reduced macrophage recruitments and the M1–M2 polarization of macrophage in ccRCC tissues. Together, DLK2 may acts as a novel biomarker, even therapeutic target in ccRCC. However, this study lacks experimental validation, and further studies are required to support this viewpoint.
