Abstract:
Gastric cancer-related long non-coding RNA1 (GClnc1) is an emerging oncogenic regulator in multiple malignancies, including gastric, colorectal, ovarian, and bladder cancers, as well as osteosarcoma. It promotes proliferation, inhibits apoptosis, and enhances drug resistance and metastasis. Mechanistically, GClnc1 dysregulates key cancer-related regulators and pathways, such as p53, MYC, NF-κB, and the SIRT3/SOD2 axis. Clinically, GClnc1 shows diagnostic and prognostic potential across cancers, with aberrant expression in tissues and altered circulating levels. Notably, exosomal GClnc1 serves as a circulating biomarker for early gastric cancer detection and predicts response to fluorouracil-based chemotherapy. This review summarizes current evidence on GClnc1's regulatory mechanisms and discusses its translational applications. GClnc1 may serve as a multi-cancer biomarker and a promising therapeutic target.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
