Imprinted Gene Tumor Markers for Early Cancer Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cancer diagnosis methods rely heavily on morphological observation, which is prone to missed diagnoses due to the lack of early morphological changes, while molecular markers like genomic imprinting, which occur earlier in cancer development, are underutilized for sensitive and specific early tumor detection.
Innovation Solution
Utilizing imprinted genes as tumor markers for early tumor diagnosis through in-situ hybridization and analysis of expression patterns, including loss of imprinting and copy number variations, to provide accurate diagnostic models and devices for various cancers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If morphological observation is used for cancer diagnosis, then the diagnosis method is simple and easy to operate, but the sensitivity and accuracy are low due to lack of early morphological changes
Solution Approach 1:
The patent changes the detection parameter from morphological features to molecular biological features (genomic imprinting status). By detecting methylation status of imprinted genes, the method achieves early cancer detection before morphological changes occur, resolving the contradiction between diagnosis sensitivity and method simplicity.
Solution Approach 2:
The patent replaces the mechanical/morphological observation system with a molecular biology-based detection system. Instead of visually examining tissue morphology under microscope, the method uses molecular markers (imprinted gene expression patterns) to detect cancer, significantly improving sensitivity while maintaining operational feasibility.
2Measurement precision
If molecular markers are used for early cancer detection, then the diagnosis sensitivity is improved, but the diagnostic complexity and cost increase
Solution Approach 1:
The patent extracts and focuses on a specific molecular marker system (genomic imprinting) from the complex field of molecular biology. By selecting imprinted genes as the detection target, the method achieves early cancer detection with reduced complexity compared to comprehensive molecular profiling, balancing sensitivity improvement with practical feasibility.
3Measurement precision
If imprinted genes are used as tumor markers, then the early diagnosis accuracy is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent utilizes the universal applicability of genomic imprinting detection across different cancer types. The same detection approach (analyzing imprinted gene expression patterns) can be applied to various cancers, making the measurement process more standardized and less difficult compared to cancer-specific marker detection.

AI summary
This application provides a tumor marker and its applications. The tumor marker includes any one, or a combination of at least two, of imprinted genes Z17, Z18, Z19, Z20, Z21, Z22, Z23, Z25, Z26, Z27, and Z28. If necessary, the tumor marker may further include any one, or a combination of at least two, of imprinted genes Z1, Z2, Z3, Z4, Z5, Z6, Z8, Z9, Z10, N11, Z12, Z13, Z14, Z15, and N16. The imprinted genes in this application have significant diagnostic sensitivity when used as tumor markers for tumor diagnosis and can therefore facilitate early diagnosis of tumors, help increase patients' survival rates, and thus contribute greatly to saving patients' lives. The imprinted genes can also provide important guidance on the treatment and medication of tumors.
