Micropeptide Detection for Gene Expression Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current understanding of microRNAs (miRNAs) does not account for the potential encoding of peptides within their primary transcripts, limiting the control over gene expression modulation.
Innovation Solution
A process for detecting and identifying micropeptides (miPEPs) encoded by nucleotide sequences in the primary transcripts of miRNAs, involving the detection of open reading frames and comparing microRNA accumulation in cells with and without the corresponding peptide to determine modulation effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If microRNAs are considered only as non-coding regulatory RNAs, then the understanding of their function is simplified, but the potential for peptide encoding and additional gene expression control mechanisms is lost
Solution Approach 1:
The patent segments the primary transcript of microRNA into distinct functional regions: the microRNA coding sequence and embedded open reading frames (ORFs) that encode micropeptides. This segmentation allows recognition of multiple functional elements within a single transcript, resolving the contradiction by maintaining conceptual simplicity while revealing functional versatility.
Solution Approach 2:
The patent demonstrates that microRNA primary transcripts serve dual functions: producing regulatory microRNAs and encoding functional micropeptides through embedded ORFs. This multi-functionality principle resolves the contradiction by showing that the same molecular entity can perform multiple roles, thereby increasing adaptability without proportionally increasing complexity.
2Reliability
If traditional miRNA mechanisms are used for gene expression control, then the mechanism is well-understood and predictable, but the range of control options is limited
Solution Approach 1:
The patent introduces micropeptides as intermediary molecules that mediate gene expression control alongside microRNAs. These micropeptides act as intermediate effectors that can modulate gene expression through mechanisms distinct from microRNA-mediated repression, thereby expanding control diversity while maintaining the reliability of the established microRNA pathway.
Solution Approach 2:
The patent changes the functional parameters of microRNA primary transcripts by identifying embedded ORFs that encode peptides. This parameter change transforms the transcript from a purely regulatory RNA molecule into a hybrid molecule with both RNA and peptide coding capabilities, thereby expanding control mechanism diversity while building upon the well-understood microRNA foundation.
