Signaling Pathways and Molecular Biomarkers in Gallbladder Cancer: A State-of-the-Art Review
摘要
Gallbladder cancer (GBC) is a highly aggressive malignancy with limited therapeutic options and poor prognosis. This review explores the multifaceted etiology and molecular mechanisms underlying GBC, highlighting key pathways and biomarkers associated with its progression.
Recent findingsCentral to GBC pathogenesis are genetic mutations, epigenetic modifications, and the interplay between chronic inflammation and gallstone disease. Molecular markers such as TP53, EGFR, and PI3KCA mutations, alongside epigenetic alterations like DNA methylation, play pivotal roles in disease development. Non-coding RNAs, including miRNAs and lncRNAs, modulate oncogenic and tumor suppressor pathways, impacting proliferation, invasion, and chemoresistance. Chronic inflammation driven by bacterial infections and bile acid dysregulation fosters a tumor-promoting microenvironment, with the epithelial-mesenchymal transition (EMT) and cancer stem cells (CSCs) contributing to metastasis and drug resistance. Advances in understanding the tumor microenvironment, signaling pathways, and exosome-mediated communication offer insights into novel therapeutic targets.
SummaryThis review underscores the need for personalized medicine approaches, leveraging high-throughput sequencing and biomarker discovery to develop tailored diagnostic and therapeutic strategies. By unraveling the complex molecular landscape of GBC, this work provides a foundation for innovative treatments, improving outcomes for patients facing this formidable disease.
