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

ABSTRACT: 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 (4×44K) (Agilent, USA)

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.

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.

MIR-204 target genes

Project description:The aim of this study is to discover genes regulated by miR-204. Differential gene expression in HEK-293 cells transfected with miR-204-mimic compared to HEK-293 cells transfected with control oligo (HEK-293 control) was analyzed using the Agilent Human Whole Genome 4x44K gene expression array (Agilent Technologies, Santa Clara, CA). HEK-293 cells were transfected with either miR-204 or a control, and gene expression was analyzed using the Agilent Human Whole Genome 4x44K array. A dye-swap was performed.

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.

The role of microRNA-204 in pressure overload-induced cardiac hypertrophy

Project description:microRNAs regulate cardiac hypertrophy development, which predicts the risk of heart failure. Here we investigate the role of microRNA-204-5p (miR-204) in developing cardiac hypertrophy and cardiac dysfunction following transaortic constriction. To determine the role of miR-204, we determined the transcriptomic profile of hearts following transaortic constriction.

Progression from actinic keratosis to cutaneous squamous cell carcinoma involves miR-204 silencing and a switch towards STAT3 activation

Project description:Squamous cell carcinoma is the second most common skin cancer and frequently progress from an intraepithelial actinic keratosis. The role of microRNAs during the progression from actinic keratosis to cutaneous squamous cell carcinoma (cSCC) remains to be elicited. By using an Agilent microRNA expression microarray we found the expression of miR-204 to be markedly downregulated in cSCC when compared to actinic keratoses. DNA methylation of the TRPM3 promoter region upstream of miR-204-5p was identified as one of the repressive mechanisms that accounts for miR-204 silencing in cSCC. Functional studies on HaCaT cells revealed that this microRNA downregulates the Signal Transducer and Activator of Transcription 3 (STAT3) pathway and favours the MAPK signaling pathway, likely acting through PTPN11, a tyrosine phosphatase that is a direct miR-204 target. We found that activated STAT3, as detected by pY705-STAT3 immunofluorescence, is retained in the membrane and cytoplasm compartment in AK, whereas cSCC displayed STAT3 in the nuclei. Taken together, our data indicates that MiR-204 may act as a “rheostat” that controls the signaling towards the MAPK pathway or the STAT3 pathway.

Hedyotis diffusa-Sculellaria barbata (HD-SB) suppresses the progression of colorectal cancer cells via the hsa_circ_0039933/hsa-miR-204-5p/wnt11 axis

Project description:Our previous study confirmed that the combination of Hedyotis diffusa (HD) and Scutellaria barbata (SB) significantly inhibited colorectal cancer cells proliferation and the WNT signaling pathway. However, the exact molecular modulation remains unclear. In this study, colorectal cancer cells (SW620) were treated with 1 mg/mL HD-SB for 24 h, and high-throughput sequencing of circRNAs was performed. The level of hsa_circ_0039933 in three colorectal cancer cell lines (HT-29, SW620, and HCT116) was verified by qPCR. After transfection of hsa_circ_0039933 overexpression plasmids or small interfering RNAs, CCK8, apoptosis, cell migration, and cell invasion were utilized to evaluate the function of hsa_circ_0039933 in the progression of colorectal cancer cells. We identified hsa_circ_0039933, which was downregulated in HD-SB-induced colorectal cancer cells and positively related to colorectal cancer progression. In SW620 cells with relatively high expression of hsa_circ_0039933, interfering with the expression of hsa_circ_0039933 inhibited the proliferation, invasion, and migration of SW620 cells. In HCT116 cells with relatively low expression of hsa_circ_0039933, overexpression of hsa_circ_0039933 promoted the proliferation and invasion and migration ability of HCT116. Mechanistically, hsa_circ_0039933 targeted hsa-miR-204-5p to increase the expression of wnt11, leading to the activation of the Wnt pathway, thereby promoting the proliferation of colorectal cancer cells. This work revealed the potential molecular mechanism of HD-SB for the treatment of colorectal cancer, which was to inhibit the Wnt signaling pathway through the hsa_circ_0039933/hsa-miR-204-5p/wnt11 axis, then suppressing proliferation, migration, and invasion in colorectal cancer cell.
