MiR-204-5p may Regulate Oxidative Stress in Myopia and Myopia-Related Retinopathy

Project description:Introduction: The mechanisms underlying myopia and myopia-related retinopathy remain not fully understood. We proposed to examine the function and underlying mechanisms of miR-204-5p in myopia development. Methods: The miR-204-5p expression level was assessed in the vitreous humor (VH) of a cohort consisting of 11 patients with high myopia (HM) and 16 control patients undergoing retinal surgery. The functional implications of miR-204-5p in ARPE-19 cells were assessed, encompassing cell aggressiveness. Thioredoxin-interacting protein (TXNIP) was found as a possible target of miR-204-5p through mRNA sequencing, and its interaction with miR-204-5p was confirmed employing luciferase assay and western blotting. Furthermore, the miR-204-5p function in regulating oxidative stress was examined by measuring reactive oxygen species (ROS) accumulation. Results: miR-204-5p was found to be significantly reduced in the VH of HM patients. Overexpression of miR-204-5p suppressed cell proliferation, migration, invasion, and apoptosis in ARPE-19 cells. The bioinformatics analysis demonstrated that miR-204-5p can modulate the genes associated with pathways relevant to myopia, including glycosaminoglycan (GAG) degradation, lysosome, and TGF−beta signaling pathway. The direct targeting of miR-204-5p on TXNIP has been confirmed through validation, and its downregulation mediated the miR-204-5p impacts on ARPE-19 cells. Moreover, miR-204-5p overexpression significantly reduced ROS accumulation by targeting TXNIP. Conclusion: Our findings revealed the possible contribution of the miR-204-5p/TXNIP axis in myopia development by regulating oxidative stress, which may provide new targets and novel therapeutic strategies to combat this prevalent and debilitating condition.

Expression profile of HCT116 cells transfected with miR-204-5p

Project description:We have employed whole genome microarray expression profiling as a discovery platform to screen potential target genes of miR-204-5p in colorectal cancer cell HCT116. HCT116 cells were seeded in 6-cm2 tissue culture plates and transfected with the miR-204-5p mimic or negative control (NC) using Lipofectamine 2000 (Invitrogen, USA). After propagation for 48 hours, total RNA was extracted using TRIzol reagent (Invitrogen, USA). Expression profiling was performed using an Agilent human whole genome oligo microarray chip (4M-CM-^W44K) (Agilent, USA) Expression profiling in HCT116 cells was measured at 48 hours after transfection with miR-204-5p or negative control. Experiments were performed using the two samples without repeat experiment.

RNA-seq of miR-204-5p overexpressing 4T1 murine breast cancer cells

Project description:We established two distinct stable clones which ectopically overexpress miR-204-5p to different levels, then performed transcriptome profiling of miR-204-5p overexpressing cells compared to control 4T1 cells to understand the molecular mechanisms of the miR-204-5p’s effect on cancer cells.

MicroRNA-204-5p is a tumor suppressor and potential therapeutic target in head and neck squamous cell carcinoma.

Project description:To understand molecular mechanisms underlying miR-204-5p mediated suppression of HNSCC progression, we performed RNA-seq analysis in UM-SCC1 cells transfected with miR-204-5p mimics and control mimics. The expression of JAK2, SNAI2, TGFBR2, MAP2K4, involved in both EMT and STAT3 signaling, were all decreased in cells treated with miR-204-5p mimics.

miR-204-5p and miR-211-5p contribute to BRAF inhibitor resistance in melanoma

Project description:Purpose: Identification of miRNAs that enable resistance to BRAF inhibitors in melanoma suggests a mechanism-based strategy to limit resistance and improve clinical outcomes. Methods: We generated A375 melanoma cells resistant to Vemurafenib (VMF) with the goal of investigating changes in miRNA expression patterns that might contribute to resistance. Results: Increased expression of miR-204-5p and miR-211-5p occurring in VMF-resistant cells was determined to impact VMF response.

Astragaloside IV attenuates macrophage-derived exosomes induced peritoneal fibrosis after inflammatory injury through the miR-204-5p/Foxc1 pathway

Project description:Peritoneal dialysis (PD) is a successful renal replacement therapy for end-stage renal disease that effectively improves the quality of life. Long-term PD causes epithelial mesenchymal transformation (MMT) of peritoneal mesothelial cells, leading to peritoneal fibrosis which reduces the efficiency of PD. Macrophages are considered players in the onset and perpetuation of peritoneal injury. Yet, the mechanisms employed by macrophage-mesothelial cells communication to regulate peritoneal fibrosis are not fully elucidated resulting in lack of disease-modified drugs. This study analyzes the role of macrophage-mesothelial cell communication by intraperitoneal injection of macrophage derived exosomes in PD model rats. These results show that macrophages secrete exosomal miR-204-5p that directly targets Foxc1, leading to the activation of MMT in mesothelial cells. The data also shows that intraperitoneal injection of dissolved AS-IV can improve MMT by altering macrophage derived exosomal miRNAs. This study indicates that intercellular crosstalk between peritoneal macrophages and mesothelial cells is mediated by macrophage derived miR-204-5p-containing exosomes that control the MMT progression, providing AS-IV for prevention and treatment of PD induced peritoneal fibrosis. Our results demonstrate, for the first time, a novel role of the AS-IV on miR-204-5p/Foxc1/β-catenin axis in improving peritoneal fibrosis in vivo and vitro.
