Comprehensive resource for transcription readthrough events in healthy human tissues

Area of Science:

• Molecular Biology
• Genomics
• Transcriptomics

Background:

• Transcription readthrough (RT) produces elongated RNA molecules (RT transcripts or downstream of gene transcripts).
• The biological roles of RT transcripts in healthy human tissues remain largely unexplored.
• Previous research has linked RT transcripts to stress responses and pathological conditions.

Purpose of the Study:

• To comprehensively analyze transcription readthrough events across a wide range of healthy human tissues.
• To characterize the landscape of RT transcripts and their associated genes in normal human physiology.
• To establish a benchmark dataset for future research on RT transcriptomics and gene regulation.

Main Methods:

• Systematic collection and analysis of RT events from 43 distinct healthy human tissue samples.
• Identification and cataloging of RT events, including transcript sequences, genomic locations, and expression profiles.
• Integration of RT transcript data with comprehensive gene annotation information.

Main Results:

• Identification of 75,248 RT events derived from 35,720 transcripts across 11,692 genes.
• Detailed characterization of RT transcript sequences, genomic locations, and expression patterns in healthy tissues.
• Establishment of a comprehensive dataset linking RT transcripts to their corresponding gene annotations.

Conclusions:

• Transcription readthrough is a significant biological phenomenon occurring across diverse healthy human tissues.
• The generated dataset offers valuable insights into the role of RT transcripts in normal gene regulation.
• This work provides a foundational resource for further investigation into the functional implications of RT transcriptomics.
