Background: It is well known that the prognosis of Gastric cancer (GC) patient is affected by many factors. However, the latent impact of anoikis on the prognosis of GC patients is insufficient understood.Methods: According to the Cancer Genome Atlas (TCGA) database, we elected discrepantly expressed anoikis-related genes (ARGs). Univariate cox and the least absolute shrinkage and selection operator (lasso) analysis were applied to build the ARGs signature. The prognostic effect of the ARGs signature was also evaluated. A series of algorithms were performed to evaluate the discrepancies in the immune microenvironment. Moreover, the correlation between drug sensitivity and ARGs signature was analyzed. We also performed Real-Time Polymerase Chain Reaction (RT-PCR) to probe the signature.Results: The ARGs signature of 9 genes was constructed, which was apparently interrelated with the prognosis. The nomogram was established by combining the ARGs signature with clinicopathological characteristics. We found that the predictive power was noteworthily superior to other individual predictors. The immune microenvironment analysis indicated that ESTIMATEscore, ImmuneScores, StromalScores, tumor immune dysfunction and exclusion (TIDE) score were lower in the low-risk group, while immunophenoscore (IPS) was on the contrary. The infiltrated immune cells and immune checkpoint (ICP) expression levels were significantly different between the two groups. Furthermore, nine drugs were positively associated with the ARGs signature score. The results of RT-PCR analysis were consistent with our previous differential expression analysis.Conclusion: The developed ARGs signature could act as the biomarker and provide a momentous reference for Individual therapy of GC patients.
Neutrophil extracellular traps (NETs) and other factors play a significant role in impacting the prognosis of patients with Hepatocellular carcinoma (HCC). Nevertheless, further research is warranted to fully elucidate the prognostic implications of NETs in patients with HCC. We employed a hierarchical clustering technique to examine the Cancer Genome Atlas-Liver Hepatocellular Carcinoma (TCGA-LIHC) data and identified subtypes associated with NETs. Subsequently, we utilized LASSO regression analysis to identify a distinct gene expression pattern within these subtypes. The strength of this signature was further validated through analysis of TCGA-LIHC and International Cancer Genome Consortium-Liver Cancer (ICGC-LIRI-JP) data. Our findings resulted in the construction of a six-gene signature related to NETs, which can predict survival outcomes in HCC patients. To enhance the predictive accuracy of our tool, we developed a nomogram that integrates the NETs signature with clinicopathological characteristics. We validated the significance of NETs in HCC patients using qRT-PCR and immunohistochemistry assays, along with in vitro experiments targeting high-risk genes. Furthermore, our exploration of the immune microenvironment uncovered augmented immune-specific metrics within the low-risk cohort, implying potential disparities in immune-related attributes between the high-risk and low-risk contingents. In summary, the NETs signature we discovered serves as a valuable biomarker and provides guidance for personalized therapy in HCC patients.
In hepatocellular carcinoma (HCC) individuals, the influence of numerous variables on the HCC prognosis has gained widespread recognition. Nevertheless, there remains a need for further elucidation regarding the underlying mechanism of PANoptosis-related genes (PRGs) on HCC. A consensus clustering approach, based on the TCGA-LIHC data, was used to identify specific subtypes linked to PANoptosis in this study. Next, a signature consisting of predictive differentially expressed genes for these subtypes was established using a least absolute shrinkage and selection operator (LASSO) regression analysis. Additionally, the reliability of the signature was confirmed through verification investigations using the data from the ICGC database and TCGA-LIHC. In the end, we developed a nomogram to enhance the clinical effectiveness of our prediction tool. PRG signature in this study has been highly related to the prognosis of individuals diagnosed with HCC, which was established with six genes. Also, this signature and clinicopathological features were put together to create a nomogram. Interestingly, the forecasting efficiency of this combination approach is better than other prediction models in the reported literature. In addition, an examination of the immunological surroundings indicates that the group with low risk exhibited elevated ESTIMATE score, ImmuneScores, and StromalScores. More, significant differences in infiltrating immune cells and the expression levels of immune-related genes were found between the two groups. In HCC patients, the PRG signature exhibits potential as a biomarker, offering a significant point of reference for tailoring individual therapy.
