Integrated Transcriptomic and Proteomic Analysis

  • Service Details
  • Case Study

The transcriptome is the complete collection of information transcribed by a cell at a particular stage of development or under physiological conditions. It represents the intermediate state of gene expression. Proteins are the direct executors of life functions, and the proteome is the entire set of proteins expressed by a cell or organism. Both proteomics and transcriptomics are critical tools for obtaining gene expression information. The comprehensive analysis of proteomics and transcriptomics data can compensate for problems caused by the lack of single-omics data, noise interference and other factors. It can also reduce false positives brought about by single-omics analysis. Comprehensive analysis of proteomics and transcriptomics data can be used to explain biological problems from a holistic point of view, explore organism physiological and disease mechanisms. It is conducive to the study of the multilevel regulation of gene expression, and obtains more comprehensive information on gene expression, which can provide more comprehensive information for biomedical research, drug research and development, and agricultural research and application. It can make up for the problems caused by single-omics data, noise interference and other factors. It can also reduce false positives brought on by single histology analyses.

Purpose and advantages of integrated transcriptomics and proteomics analysis

  • The integration of the two groups can provide a "panoramic view" of expression profiles and realize the complementarity of the two groups to analyze the expression levels of mRNAs and proteins in a specific state of an organism.
  • Integration of transcriptome and proteome analysis can provide in-depth understanding of differential expression profiles, uncover key mRNAs or proteins subject to post-transcriptional regulation, and identify and validate important regulatory pathways.
  • For species for which protein databases are lacking or poorly annotated, the number of protein identifications can be substantially increased by constructing protein search libraries from transcriptome data.

Integrated Transcriptome and Proteome Analyses Reveal Organ-Specific Proteome Deterioration in Old Rats

Journal: Cell Syst

Published: 2015


Aging is a multifactorial process associated with progressive loss of physiological integrity, leading to functional decline and increased morbidity. Current studies have found that aging is associated with protein, cellular, and organ decline. The authors utilized an integrated transcriptomic and proteomic analysis approach to study gene expression, bulk translation, and cell biology in the brain and liver of aged old rats, which was used to better explain aging at the organismal level.


In this study, the authors combined birdshot mass spectrometry with subcellular isolation, RNA sequencing, and ribosome analysis to study physiological changes in the liver and brain of young and old rats (Figure 1). This integrated analysis provides a system-wide comparison between the brain, which has limited cellular renewal capacity, and the liver, which has a greater capacity for renewal, enabling the identification of specific alterations, such as protein kinases and signaling mediators in the brain, metabolic processes in the brain, and common responses that differentiate between the organs of young and old animals.

Figure 1Figure 1

The characterization of affected transcripts and proteins also suggests organ-specific differences between young and old animals. Of the 1,099 altered transcript abundances, only 48 were significantly lower than expected and were common in the brain and liver, of which 37 (77%) were consistently changed (Figure 2).

Figure 2Figure 2


By comparing two organs with different physiological and regenerative capacities, the authors distinguish between organ-specific effects and systemic effects of aging. Intuitively, this study suggests that age-specific organ-specific effects are closely related to organ function. In the liver, most age-related changes are driven by alterations in transcript abundance, suggesting age-related changes in transcriptional regulation. In contrast, the brain is affected by age primarily at the translational level. Overall, the study suggests that age-related remodeling of the brain's translational machinery may ultimately lead to changes in the translation efficiency of a subset of transcripts in older animals. Specifically, the authors found that 15% of brain transcripts were affected by translation changes (compared to 2% in the liver).

The authors did this by quantifying the molecular changes between two organs, the brain and the liver, in young and old rats. By integrating transcriptomic and proteomic analyses, they reveal that translation changes are the main cause of altered protein levels during aging. However, they also identified other levels of regulation, such as protein localization and phosphorylation. These levels are involved in proteome modification in older animals.
