Therapeutic Stress-Induced Remodeling of Transposable Elements and TE-Gene Chimeras in KYSE150 Esophageal Squamous Cell Carcinoma Cells

, strongly downregulated genes, produced novel TE-derived isoforms and were high-potential functional candidates. Epigenetic context analysis showed considerable overlap between exonized chimeras and candidate cis-regulatory elements, suggesting a potential association with regulatory genomic contexts. Pathway enrichment analysis showed synchronized transcriptomic reprogramming and cell cycle and DNA repair pathway activation and autophagy inhibition. In esophageal cancer cells, concurrent genotoxic and proteotoxic stress causes complex TE remodeling, linking traditional TE transcriptional alterations to structured TE-gene chimera development and stress-related transcriptome reprogramming.
