ZNF460-mediated upregulation of APCDD1L-DT promotes cholangiocarcinoma development by inhibiting the ubiquitin-mediated degradation of DVL2. Cancer Gene Ther 2024:10.1038/s41417-024-00826-z. [PMID: 39210030 DOI: 10.1038/s41417-024-00826-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 08/14/2024] [Accepted: 08/20/2024] [Indexed: 09/04/2024]
Abstract
Cholangiocarcinoma (CCA), known for its aggressive nature, poses a formidable challenge in the current medical landscape, particularly in targeted therapies. Against this backdrop, long non-coding RNAs (lncRNAs) have captured the attention of researchers. These unique RNAs are believed to play pivotal roles in various cancers, offering promising avenues for the development of more effective treatment strategies. Previous studies have substantiated the aberrant expression of the APCDD1L-DT in numerous human tumors, demonstrating its positive regulatory roles in disease progression. Nevertheless, the biological functions of APCDD1L-DT in CCA are still not fully understood. This study marks the inaugural documentation of APCDD1L-DT exhibiting aberrant expression in CCA specimen, establishing a close correlation with the TNM staging of tumor patients. Furthermore, suppressing APCDD1L-DT expression hinders both the viability and motility of tumor cells. Mechanistically, the abnormal activation of the transcription factor ZNF460 positively regulated APCDD1L-DT expression in CCA. This activation, in turn, propels the abnormal activation of the Wnt pathway, fostering tumor development by impeding the ubiquitin-mediated degradation of DVL2. Broadly speaking, this study provides auspicious perspectives for comprehending CCA and furnishes support for addressing this daunting malignancy.

The efficacy of ferroptosis-inducing compounds IKE and RSL3 correlates with the expression of ferroptotic pathway regulators CD71 and SLC7A11 in biliary tract cancer cells. PLoS One 2024; 19:e0302050. [PMID: 38603713 PMCID: PMC11008848 DOI: 10.1371/journal.pone.0302050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 03/27/2024] [Indexed: 04/13/2024] Open
Abstract
INTRODUCTION Biliary tract cancer (BTC) is a lethal disease with a bad overall survivability, partly arising from inadequate therapeutic alternatives, detection at a belated stage, and a resistance to common therapeutic approaches. Ferroptosis is a form of programmed cell death that depends on reactive oxygen species (ROS) and iron, causing excessive peroxidation of polyunsaturated fatty acids (PUFAs). Therefore, the objective of this investigation is, whether ferroptosis can be induced in BTC in vitro and whether this induction is dependent on specific molecular markers. METHODS The study conducted resazurin assay and IC25/50 calculation to explore the possible cytotoxic outcomes of different classes of ferroptosis-inducing substances (FINs) on a comprehensive in vitro model of 11 BTC cell lines. Combinatory treatments with different cell death inhibitors were performed to evaluate the magnitude of ferroptosis induction. To ascertain whether ferroptotic cell death occurred, liperfluo and iron assay kits were employed to evaluate lipid ROS and intracellular iron abundance. Potential biomarkers of ferroptosis sensitivity were then assessed via western blot analysis, a rtPCR panel and functional assay kits. RESULTS The study found that different FINs reduced cell viability in a cell line-dependent manner. In addition, we measured increased lipid ROS and intracellular Fe2+ levels upon exposure to FINs in BTC cells. Combining FINs with inhibitors of ferroptosis, necroptosis or apoptosis suggests the occurrence of ferroptotic events in BTC cell lines CCC-5, HuH-28 and KKU-055. Furthermore, we found that BTC cells display a heterogeneous profile regarding different molecular genes/markers of ferroptosis. Subsequent analysis revealed that sensitivity of BTC cells towards IKE and RSL3 positively correlated with CD71 and SLC7A11 protein expression. CONCLUSION Our results demonstrate that induction of ferroptosis is a promising approach to inhibit BTC cell growth and that the sensitivity of BTC cells towards ferroptosis induction might be dependent on molecular markers such as CD71 and SLC7A11.

[PMID: 38380717 DOI: 10.1002/jgm.3669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 01/02/2024] [Accepted: 01/14/2024] [Indexed: 02/22/2024] Open
Abstract
BACKGROUND This study investigated the role of the ferroptosis-related gene FTH1 in oral squamous cell carcinoma (OSCC) and evaluated the therapeutic potential of baicalin in OSCC cell treatment. METHODS A prognostic model was established by bioinformatic analysis, consisting of 12 ferroptosis related genes (FRGs), and FTH1 was selected as the most significantly up-regulated FRGs. The clinical correlation of FTH1 in OSCC samples was evaluated by both immunohistochemical and bioinformatic characterizations. The effects of FTH1 on migration, invasion, epithelial-mesenchymal transition (EMT) and proliferation were determined by wound healing assays, transwell assays, western blotting and 5'-ethynl 2'-deoxyuridine proliferation assays, respectively. The effects of FTH1 on ferroptosis were tested via ferroptosis markers and Mito Tracker staining. In addition, the therapeutic effects of baicalin on OSCC cells were confirmed using EMT, migration, invasion, proliferation and ferroptosis assays. RESULTS The 12 FRGs were predictive of the prognosis for OSCC patients, and FTH1 expression was identified as significantly up-regulated in OSCC samples, which was highly associated with survival, immune cell infiltration and drug sensitivity. Moreover, knocking down FTH1 inhibited cell proliferation, EMT and invasive phenotypes, but induced ferroptosis in OSCC cells (Cal27 and SCC25). Furthermore, baicalin directly suppressed expression of FTH1 in OSCC cells, and effectively promoted ferroptosis and inhibited the proliferation as well as EMT by directly targeting FTH1. CONCLUSIONS This study has demonstrated that FTH1 is a therapeutic target for OSCC treatment, and has provided evidence that baicalin offers a promising alternative for OSCC treatment.

Abstract
BACKGROUND This study identified and verified the characteristic differentially expressed ferroptosis-related genes (CDEFRGs) in osteosarcoma (OS). METHODS We extracted ferroptosis-related genes (FRGs), identified differentially expressed FRGs (DEFRGs) in OS, and conducted correlation analysis between DEFRGs. Next, we conducted GO and KEGG analyses to explore the biological functions and pathways of DEFRGs. Furthermore, we used LASSO and SVM-RFE algorithms to screen CDEFRGs, and evaluated its accuracy in diagnosing OS through ROC curves. Then, we demonstrated the molecular function and pathway enrichment of CDEFRGs through GSEA analysis. In addition, we evaluated the differences in immune cell infiltration between OS and NC groups, as well as the correlation between CDEFRGs expressions and immune cell infiltrations. Finally, the expression of CDEFRGs was verified through qRT-PCR, western blotting, and immunohistochemistry experiments. RESULTS We identified 51 DEFRGs and the expression relationship between them. GO and KEGG analysis revealed their key functions and important pathways. Based on four CDEFRGs (PEX3, CPEB1, NOX1, and ALOX5), we built the OS diagnostic model, and verified its accuracy. GSEA analysis further revealed the important functions and pathways of CDEFRGs. In addition, there were differences in immune cell infiltration between OS group and NC group, and CDEFRGs showed significant correlation with certain infiltrating immune cells. Finally, we validated the differential expression levels of four CDEFRGs through external experiments. CONCLUSIONS This study has shed light on the molecular pathological mechanism of OS and has offered novel perspectives for the early diagnosis and immune-targeted therapy of OS patients.

Abstract
Cholangiocarcinoma (CCA) is an aggressive cancer associated with a very poor prognosis and low survival rates, primarily due to late-stage diagnosis and low response rates to conventional chemotherapy. Therefore, there is an urgent need to identify effective therapeutic strategies that can improve patient outcomes. Flavonoids, such as quercetin and kaempferol, are naturally occurring compounds that have attracted significant attention for their potential in cancer therapy by targeting multiple genes. In this study, we employed network pharmacology and bioinformatic analysis to identify potential targets of quercetin and kaempferol. The results revealed that the target genes of these flavonoids were enriched in G2/M-related genes, and higher expression of G2/M signature genes was significantly associated with shorter survival in CCA patients. Furthermore, in vitro experiments using CCA cells demonstrated that quercetin or kaempferol induced cell-cycle arrest in the G2/M phase. Additionally, when combined with a Smac mimetic LCL-161, an IAP antagonist, quercetin or kaempferol synergistically induced RIPK1/RIPK3/MLKL-mediated necroptosis in CCA cells while sparing non-tumor cholangiocyte cells. These findings shed light on an innovative therapeutic combination of flavonoids, particularly quercetin and kaempferol, with Smac mimetics, suggesting great promise as a necroptosis-based approach for treating CCA and potentially other types of cancer.
