Abstract
This editorial comments on the manuscript by Chang et al, focusing on the still elusive interplay between epigenetic regulation and autophagy in gastrointestinal diseases, particularly cancer. Autophagy, essential for cellular homeostasis, exhibits diverse functions ranging from cell survival to death, and is particularly implicated in physiological gastrointestinal cell functions. However, its role in pathological backgrounds remains intricate and context-dependent. Studies underscore the dual nature of autophagy in cancer, where its early suppressive effects in early stages are juxtaposed with its later promotion, contributing to chemoresistance. This discrepancy is attributed to the dysregulation of autophagy-related genes and their intricate involvement in cellular processes. Epigenetic modifications and regulations of gene expression, including non-coding RNAs (ncRNAs), emerge as critical players in exerting regulatory control over autophagy flux, influencing treatment responses and tumor progression. Targeting epigenetic mechanisms and improving strategies involving the inhibition or induction of autophagy through pharmacological or genetic means present potential avenues to sensitize tumor cells to chemotherapy. Additionally, nanocarrier-based delivery of ncRNAs offers innovative therapeutic approaches. Understanding the intricate interaction between autophagy and ncRNA regulation opens avenues for the development of targeted therapies, thereby improving the prognosis of gastrointestinal malignancies with poor outcomes.
Core Tip: Understanding the intricate interplay between autophagy, epigenetics, and non-coding RNA (ncRNA) regulation in gastrointestinal (GI) cancers is crucial for devising effective therapeutic interventions. Autophagy exhibits a dual role in cancer progression, impacting treatment response rates, and its modulation through epigenetic alterations and ncRNA regulation offers promising avenues for targeted therapies. Developing strategies to manipulate autophagy, particularly via epigenetic mechanisms and nanocarrier-based ncRNA delivery systems, holds immense potential to enhance the effectiveness of chemotherapy and improve outcomes in GI malignancies.
