Application and Advantages of Omics Technologies in Post-Translational Modification Identification

Post-transcriptional modification refers to the chemical modification processes that RNA molecules undergo during gene transcription. These modifications can affect the stability, transport, translation, and function of RNA, playing a crucial role in the regulation of cellular physiological processes. With the rapid development of omics technology in recent years, researchers can gain a more comprehensive understanding of the types and functions of post-transcriptional modifications, thereby revealing their important role in disease occurrence and development.

 

The Development of RNA Sequencing Technology

With the emergence of high-throughput sequencing technology, RNA sequencing has become an important means to study post-transcriptional modifications. Traditional Sanger sequencing methods have limited the comprehensive study of post-transcriptional modifications due to high costs and low throughput. However, next-generation sequencing technologies like RNA-Seq and MeRIP-Seq can efficiently and accurately detect and quantify RNA's post-transcriptional modifications.

 

The Application of RNA-Seq Technology in the Identification of Post-Transcriptional Modifications

RNA-Seq technology transforms RNA molecules into cDNA and performs high-throughput sequencing, which can obtain the information of the entire transcriptome. In the identification of post-transcriptional modifications, RNA-Seq can help researchers identify and quantify various post-transcriptional modifications, such as N6-methyladenosine (m6A), 5-hydroxymethylcytosine (5hmC), etc. By analyzing RNA-Seq data, we can understand the distribution pattern, differential expression, and functional annotation of post-transcriptional modifications, thereby revealing their regulatory mechanism in gene regulation and disease occurrence.

 

The Application of MeRIP-Seq Technology in the Identification of Post-Transcriptional Modifications

MeRIP-Seq is an antibody-enrichment-based sequencing technology that can efficiently identify and quantify m6A modifications. This technology enriches RNA molecules with m6A modifications using specific antibodies, followed by high-throughput sequencing, to get the whole transcriptome profile of m6A modifications. MeRIP-Seq technology has the advantages of high sensitivity and high specificity, which can help researchers comprehensively understand the function of m6A modifications in gene regulation and disease occurrence.
