Core Tip
Core Tip: Metallomics, a study of metallic elements in biological systems, is critical for understanding gastric cancer (GC). It helps identify biomarkers for early diagnosis and offers insights into treatment strategies. Novel biomarkers like matrix metalloproteinases, ferritin, and zinc (Zn2+) finger proteins can improve the sensitivity and accuracy of GC diagnosis compared to conventional tumor markers. Role of metals in GC: (1) Iron: Altered iron metabolism is linked to GC progression and can serve as a prognostic marker; (2) Copper: Copper imbalances contribute to GC development, and supplementation may enhance therapeutic effects; (3) Zn2+: Zn2+ stability is essential for cell function, and imbalances may indicate GC risk; and (4) Calcium: Abnormal calcium signal transduction may promote the occurrence, migration, invasion and other aspects of GC and affect prognosis. Metallomics faces challenges in identifying and quantifying metal-related biomarkers, dealing with low concentrations of elements, and overcoming issues with drug resistance. Advancements in analytical techniques and combining metal-based drugs with traditional therapies could improve GC diagnosis and treatment outcomes.
