Cancer Heterogeneity and Cancer Cell Plasticity: Molecular Mechanisms and Precision Therapy

MedComm, Volume 7, Issue 7, July 2026.
Tumor progression is driven by heterogeneity occurring across multiple biological scales. At the molecular level, tumor cells exhibit alterations across distinct omics layers, including genomic mutations, epigenomic reprogramming, transcriptional changes, and proteomic remodeling, collectively shaping tumor cell phenotypes and functional states.

The STAT3‐CCND2 Axis Drives a Proliferative Metaplastic Precursor Population in Gastric Intestinal Metaplasia

Journal of Cellular and Molecular Medicine, Volume 30, Issue 14, July 2026.
ABSTRACT Gastric intestinal metaplasia (GIM) is a crucial precancerous lesion with ill‐defined drivers, and identifying regulators of its early proliferation and reprogramming is key to interception. We integrated epigenomic‐transcriptomic analysis of human GIM and normal tissues, validated targets via dual‐luciferase assay, and mapped cellular ...
