MiRNA-sequencing of HGC27 and AGS cells with FN1 3' UTR overexpression

ABSTRACT: As a key protein in the tumor microenvironment, FN1 has been proven to promote cancer in a variety of cancer species. However, in our previous study on gastric cancer, it was found that FN1 protein expression in patient tissues was not significantly correlated with prognosis, and clinical data analysis was only correlated with T stage of gastric cancer. Analysis of the relationship between FN1 mRNA expression level and prognosis by TCGA-STAD database revealed that high FN1 mRNA expression was significantly correlated with poor prognosis. Moreover, many miRNA binding sites were found on FN1 3' UTR by database prediction, so we speculated that FN1 played different functions at mRNA and protein levels, and FN1 3' UTR might function as ceRNA. At present, FN1 3' UTR overexpression has been proved to significantly promote the invasion and metastasis of gastric cancer in vivo and in vitro, and its effect is stronger than FN1 protein. Therefore, in this study, miRNA sequencing, which was used to find those miRNAs bound to FN1 3’UTR, was carried out to further explore its cancer-promoting mechanism.

RNA-sequencing of HGC27 cells with and without FN1 3' UTR overexpression

Project description:As a key protein in the tumor microenvironment, FN1 has been proven to promote cancer in a variety of cancer species.

At present, FN1 3' UTR overexpression has been proved to significantly promote the invasion and metastasis of gastric cancer in vivo and in vitro, and its effect is stronger than FN1 protein. Therefore, in this study, transcriptome sequencing of FN1 3' UTR after overexpression was carried out to further explore its cancer-promoting mechanism.

FTO alleviates psoriasis-like dermatitis through the regulation of FN1

Project description:FTO was found to inhibit keratinocyte inflammation and proliferation in both in vitro and in vivo settings, independent of m6A demethylase function. RNA-seq was used to identify fibronectin (FN1,FN) as a potential target for FTO. FTO does not rely on demethylase activity to decrease FN1 expression. The anti-inflammatory and anti-proliferative effects of FTO on psoriasis partly depend on FN1. FTO may regulate the skipping of EDA exon in FN1.

YangziChen2024 - Metabolic Machine Learning Predictor Model for Diagnosis of Gastric Cancer

Project description:The paper "Metabolomic Machine Learning Predictor for Diagnosis and Prognosis of Gastric Cancer" addresses the need for non-invasive diagnostic tools for gastric cancer (GC). Traditional methods like endoscopy are invasive and expensive. The authors conducted a targeted metabolomics analysis of 702 plasma samples to develop machine learning models for GC diagnosis and prognosis. The diagnostic model, using 10 metabolites, achieved a sensitivity of 0.905, outperforming conventional protein marker-based methods. The prognostic model effectively stratified patients into risk groups, surpassing traditional clinical models. I have successfully reproduced the diagnosis model from the paper. This machine learning-based system differentiates GC patients from non-GC controls using metabolomics data from plasma samples analyzed by liquid chromatography-mass spectrometry (LC-MS). The model focuses on 10 metabolites, including succinate, uridine, lactate, and serotonin. Employing LASSO regression and a random forest classifier, the model achieved an AUROC of 0.967, with a sensitivity of 0.854 and specificity of 0.926. This model significantly outperforms traditional diagnostic methods and underscores the potential of integrating machine learning with metabolomics for early GC detection and treatment.

Comprehensive Molecular Characterizations of Gastric Tissue and Gastric Cancer Revealed by Single-cell RNA-seq

Project description:Molecular knowledge of normal gastric tissues and gastric cancers remains incomplete. Here, we used single-cell RNA-seq to study the cell diversity of gastric tissues and gastric cancers. The expression landscape of normal gastric cell types and several candidate stem cell markers were obtained. Surprisingly, nearly all cell types in the antrum could transdifferentiate to intestinal metaplasia (IM). We also explored intra-tumoral heterogeneity and identified four common features of gastric cancer. In addition, we classified tumor cells into three major subtypes, which are associated with their prognosis. Finally, the proportions of mesenchymal and endothelial cells in the tumor microenvironment (TME) were negatively correlated with the prognosis of gastric cancer. Therefore, our work provides comprehensive molecular characterizations of both gastric development and gastric cancer at single-cell resolution and has significant potential to inspire better treatment strategies for gastric cancer. Keywords: Expression profiling by high throughput sequencing

ELK3 controls gastric cancer cell migration and invasion by regulating ECM remodeling-related genes

Project description:Current therapeutic strategies, including surgery and chemotherapy, for gastric cancer improve survival; however, the survival rate for those with metastatic gastric cancer is very low. The molecular mechanisms underlying dissemination of gastric cancer cells to distant organs are unknown. Here, we show that the ELK3 gene is necessary for migration and invasion of gastric cancer cells. The ELK3 gene modulates expression of extracellular matrix (ECM) remodeling-related genes such as LOXL2, SERPINF1, COL16A1, NID1, and SNAI1 to facilitate cancer cell dissemination. Our in silico analysis indicated that ELK3 expression was positively correlated with these ECM remodeling-related genes in gastric cancer cells and human gastric cancer patients. High expression of ELK3 and other ECM remodeling-related genes was also closely associated with a worse prognosis of gastric cancer patients. These findings suggested that ELK3 acts as an important regulator of gastric cancer dissemination by regulating ECM remodeling.
