Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively detect oxidative stress in cells using genomic samples, which is crucial for preventing further damage from ROS-induced conditions like psoriasis or skin cancer.
Innovation Solution
A method is developed to detect oxidative stress by comparing the methylation status of CpG sites in a test cell to a control cell, utilizing differential methylation patterns as biomarkers, particularly through bisulfite treatment and epigenetic analysis of CpG sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to detect oxidative stress, then detection can be performed, but they cannot effectively detect OS using genomic samples from the body
Solution Approach 1:
The patent changes the detection parameter from general oxidative stress markers to specific epigenetic markers (DNA methylation status at CpG sites). This parameter change enables effective detection using genomic samples by focusing on heritable epigenetic modifications that reflect oxidative stress exposure, thereby resolving the contradiction between detection effectiveness and applicability to genomic samples
2Loss of time
If early detection of oxidative stress is achieved, then timely intervention can prevent further damage, but no official method exists for detecting OS in cells using body genomic samples
Solution Approach 1:
The patent performs preliminary detection of epigenetic markers that indicate oxidative stress exposure before significant cellular damage occurs. By detecting DNA methylation changes at CpG sites as early biomarkers, the method enables timely intervention while maintaining scientific validity, thus resolving the contradiction between early detection timing and method reliability
3Duration of action of stationary object
If epigenetic markers are used for detection, then long-term inheritable biomarkers are available, but the method complexity increases
Solution Approach 1:
The patent extracts and focuses on specific epigenetic markers (DNA methylation status at particular CpG sites) from the complex genome. By selecting and analyzing only these specific heritable markers rather than performing comprehensive genomic analysis, the method achieves long-term biomarker stability while reducing detection complexity to manageable levels

AI summary
The present invention is related to a method of identifying oxidative stress (OS) in a test cell, comprising(a) determining the methylation status of at least one CpG site in a DNA sample obtained from the test cell,(b) comparing the methylation status of the CpG site from (a) with that of a control without OS,wherein difference in the methylation status of the CpG site in the test cell compared to the CpG site in the control is indicative of the test cell having OS.
