Abstract
Background: Esophageal squamous cell carcinoma (ESCC) is closely linked to chronic inflammation, but the transcriptional mechanisms connecting epithelial inflammatory remodeling with malignant transformation remain incompletely understood.
Methods: We integrated secondary analysis of published single-cell epithelial transition-state data, virtual SP1 perturbation, TCGA analyses, xCell immune infiltration analysis, TIDE-based exploratory immunotherapy prediction, Co-IP/MS, and a 4NQO-induced mouse model to investigate SP1-associated network remodeling during ESCC carcinogenesis.
Results: SP1 regulatory importance increased across pairwise epithelial state comparisons. In adjacent normal epithelial cells, virtual SP1 overexpression affected genes linked to inflammatory response, NF-κB-related signaling, epithelial stress remodeling, and proliferation. SP1 expression correlated with immune infiltration features and immune checkpoint gene expression, and TIDE analysis suggested an association with predicted immunotherapy-related features. SP1-binding partners were enriched in RNA metabolism, RNA splicing, and nuclear protein-complex annotations, suggesting potential non-canonical regulatory associations that require further experimental validation.
Conclusions: SP1 may represent a progressively enhanced transcriptional hub during inflammation-associated ESCC carcinogenesis, with state-dependent network remodeling spanning epithelial inflammatory stress, malignant transformation, and tumor immune features.
