Importance of Biological Replicates for Inter-Sample Correlation
Biological replicates are crucial for RNA-seq experiments. We assess the correlation of gene expression levels between samples to verify the reliability and reproducibility of experiments. A high correlation coefficient indicates a high similarity between samples, ensuring the quality of the data.

Fig. 1: Correlation of gene expression levels between different samples. The closer the correlation coefficient is to 1, the higher the similarity between the samples.
Differential Gene Expression (DEG) Analysis
Our differential gene expression analysis identifies differentially expressed genes under different conditions. We generate a DEG list and provide data visualizations, including volcano plots, cluster analysis, and pathway enrichment analysis.
-
Volcano Plots: Visualize the distribution of up-regulated and down-regulated genes.

Fig. 2: The x-axis in the volcano plot shows the fold change in gene expression between different samples, while the y-axis shows the statistical significance of the difference.
-
Cluster Analysis: Groups genes with similar expression patterns and visualizes them in a heatmap.

Pathway Enrichment Analysis
We conduct enrichment analysis to identify significant biological pathways associated with differentially expressed genes. This includes:
-
Gene Ontology (GO) Analysis: Identifies significantly enriched biological processes, molecular functions, and cellular components.
-
KEGG Pathway Analysis: Identifies significantly enriched metabolic or signal transduction pathways.
-
Reactome Pathway Analysis: Focuses on reactions and biological pathways in human models.
-
Human Disease Ontology (DO) Analysis: Uncovers associations between gene function and human diseases.
