Pan-Cancer Landscape of Magnesium Homeostasis: Bulk Omics Research and Single-Cell Sequencing Validation.

ABSTRACT:

Introduction

Magnesium homeostasis is critical for cellular growth and metabolism, yet its pan-cancer implications remain poorly characterized. This study aims to comprehensively analyze magnesium homeostasis across 33 cancer types, exploring its role in tumorigenesis, immune regulation, and therapeutic potential. Key magnesium homeostasis-related genes (e.g., ANK3, CNNM2) were significantly downregulated in most tumors, correlating with improved prognosis. Magnesium homeostasis scores (MHS) were reduced in cancers and linked to lower tumor mutational burden (TMB), microsatellite instability (MSI), immune dysfunction, and checkpoint gene expression. Single-cell sequencing revealed elevated MHS in CD8 + T cells, suggesting immune modulation roles.
