Dysregulated expression of ncRNAs alters gene expression, which is implicated in the pathogenesis of several malignancies and inflammatory diseases. Gastric cancer is the fifth most frequently diagnosed cancer and the fourth most common cause of cancer-related death. Studies have found that altered expression of ncRNAs may contribute to tumourigenesis through regulating proliferation, apoptosis, drug resistance and metastasis. This review describes the potential use of ncRNAs as diagnostic and prognostic biomarkers.

Introduction  \nGastric cancer (GC) is the fifth most frequently diagnosed cancer and the fourth most common cause of cancer-related death [1] . Based on the molecular profile, GC can be subdivided into gnomically stable, chromosomally unstable, microsatellite unstable and Epstein–Barr virus positive [2] . Examining the molecular profile of tumours introduced a significant breakthrough in the field of oncology, as it allows for the introduction of targeted therapies. For example, patients with GC overexpressing human epidermal growth factor receptor 2 (HER2) can be treated with a directed monoclonal antibody, trastuzumab [2,3] . Furthermore, multiple other targets are being examined as potential candidates for the treatment of GC [4] . Unfortunately, many patients with GC are diagnosed at advanced stages of the disease. Therefore, investigating strategies for early detection of GC could allow patients tobe treated earlier. Moreover, the identification of biomarkers that could discriminate between treatment responders and non-responders, as well as factors associated with the prognosis, could improve long-term treatment outcomes. Currently, the commonly used and standardised tumour markers are tumour antigens and ectopic hormones [5] . In this review, we discuss the potential use of non-coding RNAs (ncRNAs) as diagnostic and prognostic biomarkers and t","cbCaiquoENN9ckZN","https://ap.wps.com/l/cbCaiquoENN9ckZN","pdf",1676204,27,"English","# Introduction\n# An Overview of Non-Coding RNA\n## ncRNA families and interactions\n## Mechanisms of ncRNA regulation","[{\"question\":\"What types of non-coding RNAs are discussed in this review?\",\"answer\":\"The review covers microRNAs, long non-coding RNAs, and circular RNAs, alongside other ncRNA categories such as small ncRNAs and related regulatory groups.\"},{\"question\":\"How can altered ncRNA expression contribute to gastric cancer?\",\"answer\":\"Dysregulated ncRNAs change gene expression and may drive tumour development by regulating proliferation, apoptosis, drug resistance, and metastasis.\"},{\"question\":\"How are ncRNAs proposed to be used clinically in gastric cancer?\",\"answer\":\"The review describes ncRNAs as potential diagnostic and prognostic biomarkers, and it discusses their involvement in key signalling pathway interactions relevant to gastric cancer pathogenesis.\"}]","Non-Coding RNA as Biomarkers and Their Role in the Pathogenesis of Gastric Cancer - A Narrative Review | PDF",1790014493,68]
