CircEZH2 promotes gallbladder cancer progression and lipid metabolism reprogramming through the miR-556-5p/SCD1 axis.

ABSTRACT: Gallbladder cancer (GBC) is characterized by a high degree of malignancy and a poor prognosis. This study revealed that circEZH2 was frequently upregulated in GBC tissues and correlated with advanced tumor-node-metastasis (TNM) stage in GBC patients. In vitro and in vivo experiments confirmed that circEZH2 promoted the proliferation and inhibited the ferroptosis of GBC. Besides, this study discovered that circEZH2 regulated lipid metabolism reprogramming in GBC cells. Mechanistically, circEZH2 promotes SCD1 expression by sponging miR-556-5p in GBC cells. In addition, IGF2BP2 enhances the stability of circEZH2 in an m6A-dependent manner, while circEZH2 suppresses the ubiquitination and degradation of IGF2BP2 by binding to IGF2BP2. Taken together, our findings indicated that circEZH2, upregulated via a positive feedback loop between circEZH2 and IGF2BP2, promotes GBC progression and lipid metabolism reprogramming through the miR-556-5p/SCD1 axis in GBC. circEZH2 may serve as a potential therapeutic target for GBC.

Project description:The incidence of Poorly cohesive carcinoma (PCC) has steadily risen in recent years, posing a significant clinical challenge. To reveal the anti-tumor effects of Jianpi Yangzheng Xiaozheng granule (JPYZXZ) in PCC, an initial investigation was performed using CCK-8, colony formation, scratch, and transwell assays. This was followed by network pharmacology studies to gain a deeper understanding of JPYZXZ's impact on gastric cancer (GC). Then reactive oxygen species (ROS), Fe2+, malondialdehyde (MDA), glutathione (GSH), Oil Red O staining, BODIPY493/503, triglyceride (TG), and cholesterol (TC) assay kits and western blot (Wb) analysis were applied to exam the regulatory effects of JPYZXZ on ferroptosis and lipid metabolism. Additionally, molecular docking studies and Wb analysis were used to further investigate the mechanisms of JPYZXZ on PCC. Finally, in vivo animal studies were conducted. The results show that JPYZXZ can inhibit the proliferation and migration of PCC cell. It increases the levels of ROS, Fe2+, MDA, while declining the content of GSH, TC, TG, and lipid droplet accumulation within cellular compartments. Wb indicates that JPYZXZ can negatively regulate the expression of proteins, including glutathione peroxidase 4 (GPX4), cystine/glutamate antipoter SLC7A11 (xCT), fatty acid synthase (FASN), and acetyl coenzyme A carboxylase 1 (ACC1). Furthermore, ferrostatin-1 (fer-1) is able to reverse the effects of JPYZXZ on the aforementioned markers of ferroptosis and lipid metabolism. Molecular docking analyses reveal that JPYZXZ exhibits a favorable binding affinity towards Stearoyl-Coenzyme A desaturase 1 (SCD1). Mechanism studies demonstrate that JPYZXZ is capable of down-regulating the expressions of proteins like SCD1, β-catenin, GPX4, and xCT, which is analogous to the effects of SCD1 knockdown and the application of SCD1 inhibitor A939572. Nevertheless, when SCD1 is knocked down, JPYZXZ is unable to further downregulate the expressions of these proteins. Animal studies have corroborated the in vitro tumor-inhibiting effects of JPYZXZ. Therefore, this study offers the first evidence that JPYZXZ inhibits PCC progression by orchestrating ferroptosis and altering lipid metabolism, mediated by the SCD1/Wnt/β-catenin pathway.

Project description:Esophageal squamous cell carcinoma (ESCC), one of the most lethal cancers, has become a global health issue. Stearoyl-coA desaturase 1 (SCD1) has been demonstrated to play a crucial role in human cancers. However, pan-cancer analysis has revealed little evidence to date. In the current study, we systematically inspected the expression patterns and potential clinical outcomes of SCD1 in multiple human cancers. SCD1 was dysregulated in several types of cancers, and its aberrant expression acted as a diagnostic biomarker, indicating that SCD1 may play a role in tumorigenesis. We used ESCC as an example to demonstrate that SCD1 was dramatically upregulated in tumor tissues of ESCC and was associated with clinicopathological characteristics in ESCC patients. Furthermore, Kaplan-Meier analysis showed that high SCD1 expression was correlated with poor progression-free survival (PFS) and disease-free survival (DFS) in ESCC patients. The protein-protein interaction (PPI) network and module analysis by PINA database and Gephi were performed to identify the hub targets. Meanwhile, the functional annotation analysis of these hubs was constructed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Functionally, the gain-of-function of SCD1 in ESCC cells promoted cell proliferation, migration, and invasion; in contrast, loss-of-function of SCD1 in ESCC cells had opposite effects. Bioinformatic, QPCR, Western blotting and luciferase assays indicated that SCD1 was a direct target of miR-181a-5p in ESCC cells. In addition, gain-of-function of miR-181a-5p in ESCC cells reduced the cell growth, migratory, and invasive abilities. Conversely, inhibition of miR-181a-5p expression by its inhibitor in ESCC cells had opposite biological effects. Importantly, reinforced SCD1 in miR-181a-5p mimic ESCC transfectants reversed miR-181a-5p mimic-prevented malignant phenotypes of ESCC cells. Taken together, these results indicate that SCD1 expression influences tumor progression in a variety of cancers, and the miR-181a-5p/SCD1 axis may be a potential therapeutic target for ESCC treatment.
