## Executive GIST (TL;DR)
- Cancer progression involves widespread **DNA methylation** reprogramming, including promoter hypermethylation of tumor suppressor genes and global hypomethylation that alters gene regulation and phenotype. - The authors previously defined the **Methylscape**, a cancer-specific methylation architecture featuring clustered promoter hypermethylation with gene-body hypomethylation that changes DNA biophysical properties. - Methylation-patterned DNA shows enhanced physical affinity for **gold surfaces**, enabling selective enrichment of hypermethylated regions by gold-based capture. - In a TGF-β–induced breast cancer epithelial–mesenchymal transition (EMT) model, DNA from the mesenchymal state exhibited increased **Methylscape enrichment**, indicating sensitivity to subtle epigenetic remodeling associated with progression. - The study combined gold-based DNA desorption enrichment with methylation sequencing and qPCR to demonstrate preferential enrichment of hypermethylated regions on gold. - Based on these principles, the team developed a low-cost, disposable **screen-printed electrode** platform intended for stage-specific breast cancer monitoring. - The authors propose that Methylscape functions as a biophysical biomarker that could enable noninvasive, real-time monitoring of cancer progression and has potential for clinical translation. - Specific experimental details, numeric performance metrics, cohort sizes, and validation data were not reported in the provided abstract and must be retrieved from the full article for implementation or clinical evaluation.

We previously introduced the Methylscape, a cancer-specific DNA methylation landscape characterized by clustered promoter hypermethylation and gene body hypomethylation that enhances DNA's physical affinity for gold surfaces. Here, we demonstrate that Methylscape can be leveraged to monitor cancer progression. In a TGF-β-induced breast cancer epithelial-mesenchymal transition (EMT) model, we observe increased Methylscape enrichment of mesenchymal-state DNA, indicating that this method can sensitively detect subtle epigenetic remodelling linked to tumour progression. Using a gold-based DNA desorption enrichment strategy coupled with methylation sequencing and qPCR, we show that hypermethylated regions are preferentially enriched on gold surface. Finally, we developed a low-cost, disposable screen-printed electrode platform for stage-specific breast cancer monitoring. Together, these findings establish Methylscape as a promising biophysical biomarker for non-invasive, real-time monitoring of cancer progression, advancing its potential for clinical translation.
