RNA Modulation of SUV39H1 Expression in Immune Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for modulating SUV39H1 expression in immune cells are limited in their ability to effectively enhance memory potential and survival capacity of T cells and NK cells.
Innovation Solution
The use of specific RNAs, including long noncoding RNAs (lncRNAs) and short hairpin RNAs (shRNAs), that target the SUV39H1 gene to inhibit its expression, thereby reducing SUV39H1 protein levels and affecting chromatin rearrangements and gene expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shRNA is used to inhibit SUV39H1 expression, then memory potential and survival capacity are enhanced, but device complexity increases due to need for plasmid vectors and genomic integration
Solution Approach 1:
The invention extracts the essential functional element (RNAi sequence) from the complex shRNA/plasmid system and delivers it directly as a synthetic RNA molecule, eliminating the need for plasmid vectors, genomic integration, and cellular processing machinery while retaining the gene silencing function
Solution Approach 2:
Instead of introducing genetic material that requires cellular processing (shRNA in plasmids), the invention uses a direct copy of the functional RNA molecule (synthetic RNAi sequence) that can immediately bind and silence the target gene without requiring transcription, processing, or genomic integration
2Duration of action of moving object
If shRNA is used for long-term knockdown, then duration of action increases, but ease of operation decreases due to complex delivery and integration requirements
Solution Approach 1:
The invention extracts the RNAi sequence from the complex shRNA delivery system and delivers it as a simple synthetic RNA molecule, dramatically simplifying the delivery process while maintaining effective gene silencing
Solution Approach 2:
The invention changes the physical state and delivery parameters from genetic material requiring cellular processing (shRNA in plasmids) to a stable synthetic RNA molecule that can be delivered directly, improving ease of operation while achieving comparable or superior duration of action
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Inhibiting SUV39H1 expression in immune cells leads to enhanced memory potential, increased survival capacity, and improved anti-cancer activity, as well as reduced exhaustion of these cells.
Implementation Method 1
Small hairpin RNAs (shRNA) are sequences of RNA, typically about 80 base pairs in length, that include a region of internal hybridization that creates a hairpin structure. shRNA molecules are processed within the cell to form siRNA which in turn knock down gene expression.
Implementation Method 2
Small hairpin RNAs (shRNA) are sequences of RNA, typically about 80 base pairs in length, that include a region of internal hybridization that creates a hairpin structure.
Implementation Method 3
Histone methyltransferases promote chromatin rearrangements into euchromatin (open, actively transcribed chromatin) and heterochromatin (closed, inactive chromatin) via their post-translational modifications of histone molecules at the nucleosomes.
