Protein and Transcriptome Joint Analysis
Proteomics and transcriptomics are important tools for understanding gene expression. Integrative analysis of proteomic and transcriptomic data provides a more comprehensive understanding of gene expression.

The relationship between proteomics and transcriptomics
According to the central dogma, genetic information is transferred from DNA to RNA through transcription, and then translated into various proteins by RNA. These proteins can feedback into the process of DNA replication and RNA transcription, and can also catalyze the production of metabolic products. The study of the transmission and expression of genetic information corresponds to a series of 'omics' research, including genomics (corresponding to DNA), transcriptomics (corresponding to RNA), proteomics (corresponding to proteins), and metabolomics (corresponding to metabolic products), among others. It is evident that while these omics have different research objectives, they are closely related. Integrating multi-omics research and data analysis can better explain biological phenomena. From a biological perspective, the transcriptome represents the intermediate state of gene expression, while proteins are the direct executors of function. Conducting system research on biological samples by combining transcriptomics and proteomics data allows for direct observation of the association between mRNA and proteins, thereby explaining biological questions more comprehensively.

Integrative analysis of proteomics and transcriptomics
The integrative analysis of proteomics and transcriptomics aims to combine proteomic and transcriptomic data for analysis. The transcriptome refers to all RNA transcripts present in a given biological or experimental sample. Currently, nearly the entire transcriptome can be captured using strategies similar to DNA screening, such as microarrays and sequencing technologies. Transcriptome sequencing is more comprehensive, achieving higher coverage to capture almost any form of RNA. The proteome represents the complete set of proteins in a given cell, tissue, or biological sample at a certain developmental or cellular stage. Proteomics includes both qualitative and quantitative studies of the proteome, primarily using mass spectrometry-based techniques.
