Transcriptomics Services: RNA-Seq Data Analysis for Microbial and Host Transcriptomes

 

 

From raw FASTQ files to differential gene expression, functional enrichment, and publication-ready figures.

What is Transcriptomics and Why Does It Matter

Transcriptomics is the study of the transcriptome, the complete set of RNA transcripts produced by cells under specific conditions. Unlike genomics, which reveals the genetic potential of an organism, transcriptomics provides a dynamic snapshot of gene activity, showing how organisms respond to stimuli, environments, or treatments. For a more detailed explanation about what transcriptomics is, you should read the dedicated post in our blog!

While genomics, metagenomics, or microbiome analysis can help identify which organisms or genes are present, transcriptomics reveals which genes are actively expressed and how expression changes across conditions. RNA-seq analysis is therefore often integrated withother approaches such as metagenomics, microbiome analysis or microbial genomics.

This information is crucial for:

  • Understanding functional responses to stress or treatment

  • Identifying biomarkers or drug targets

  • Exploring regulatory pathways and gene networks

What Can You Achieve with RNA-Seq Analysis?

RNA-seq analysis provides insight into the functional biology of your system by measuring gene expression across conditions. Whether you are studying microbes, hosts, or mixed systems, transcriptomics can help identify regulatory responses, pathway changes, and condition-specific expression patterns.

 

  • Identify Key Regulatory Genes

    Uncover transcription factors and regulators that control pathways of interest — from virulence to stress response.

  • Compare Gene Expression Across Conditions

    Understand how gene activity shifts between time points, treatments, or environments, revealing differential patterns of expression.

  • Explore Pathway Activation and Suppression

    Assess which biological pathways are turned on or off under specific conditions using enrichment analysis and pathway databases.

  • Support Hypothesis-Driven or Exploratory Research

    Generate new hypotheses or validate existing ones by measuring transcript-level responses in a high-throughput, quantitative way.

Applications of Our RNA-Seq Data Analysis Services

Functional Genomics

Identify which genes are up- or downregulated under different conditions, complementing genome annotation with real-time gene expression data.

Host–Microbe Interaction Studies

Reveal how hosts and microbes influence each other at the gene expression level — a powerful extension of microbiome analysis.

Comparative Transcriptomics

Compare expression profiles across strains, species, or experimental conditions to identify pathways involved in resistance, adaptation, or virulence — often alongside comparative genomics.

Drug & Treatment Response

Understand how organisms respond at the molecular level to antibiotics, stress, or compounds, enabling biomarker discovery and precision intervention strategies.

Environmental or Evolutionary Stress Responses

Explore how transcriptomes shift in response to temperature, salinity, pH, or nutrient limitation — ideal for researchers working with environmental transcriptomics or host-associated response studies.

Integration with Other -Omics

Combine transcriptomic data with metagenomics, proteomics and metabolomics for systems-level understanding of cellular regulation.

RNA-Seq Analysis Workflow

Our transcriptomics pipeline processes raw RNA-Seq reads into biologically
interpretable results, including differential gene expression and pathway
analysis. For a broader explanation of a typical RNA-Seq pipeline, see our guide: RNA-Seq Data Analysis Pipeline: From FASTQ Files to Differential Gene Expression

RNA-seq bioinformatics workflow including quality control, read alignment, differential expression analysis and functional enrichment.

Our RNA-Seq Data Analysis Services 

We provide end-to-end RNA-seq analysis services for microbial, host, and environmental transcriptomes. From raw reads to publication-ready visualizations and statistical results, each workflow is tailored to your organism, experimental design, and research question. Our RNA-seq analysis pipelines rely on widely used bioinformatics tools such as STAR, HISAT2, Salmon, DESeq2, and edgeR for robust and reproducible differential gene expression analysis.

Quality Control 

We begin by assessing raw data quality with tools like FastQC and trimming low-quality bases or adapters using fastp or Trimmomatic, ensuring clean input for alignment.

Read Mapping & Quantification

Reads are aligned to a reference genome or transcriptome using STAR, HISAT2, or Salmon for fast, accurate quantification of gene or transcript expression.

Differential Expression Analysis

We identify genes with statistically significant expression changes between conditions using DESeq2, edgeR, or limma-voom, with full model transparency and p-value correction.

Functional Enrichment & Pathway Analysis

Enriched pathways and GO terms are detected to interpret the biological meaning of gene expression changes using tools like ClusterProfiler, GSEA, or KEGG/Reactome mapping.

Visualization & Reporting

You’ll receive volcano plots, heatmaps, PCA plots, and other visuals that clearly communicate your transcriptomic trends and clustering patterns.

Custom Comparisons & Metadata Integration

We adapt our models to your study design — time series, multifactorial comparisons, batch correction — and include relevant metadata in visualizations and stats.

What Data Do You Need to Start?

  • Raw RNA-Seq FASTQ files (Illumina or other platforms)
  • Single-end or paired-end sequencing reads
  • Reference genome or transcriptome (optional)
  • Sample metadata and experimental design

If a reference genome is not available, we can perform de-novo transcriptome
assembly and downstream analysis
