Abstract
Gastric cancer is one of the most common gastrointestinal malignancy with high mortality
in East Asia. Investigation of pathogenic mechanisms of gastric cancer is crucial to
develop novel therapeutic strategies and identify new therapeutic candidates. Brain-type
glycogen phosphorylase is a glycogen phosphorylase involved in glycogen metabolism, which
participates in multiple physiological and pathological processes. Overexpression of
brain-type glycogen phosphorylase has been reported in various types of cancer, such as
colorectal cancer and non-small cell lung cancer, however, the potential role of
brain-type glycogen phosphorylase in gastric cancer remains unclear. Herein, we observed
brain-type glycogen phosphorylase expression was significantly elevated in human gastric
cancer tissues and positively correlated with the clinical-pathological features including
tumor size, lymph node involvement, and tumor, node, metastasis stage of patients with
gastric cancer. We further reported brain-type glycogen phosphorylase depletion suppressed
the growth of gastric cancer, weakened the epithelial–mesenchymal transformation, and
reduced the migration and invasion ability in cell models. We further confirmed brain-type
glycogen phosphorylase depletion inhibited tumor growth and lung metastasis in mice.
Importantly, we found brain-type glycogen phosphorylase regulated the progression of
gastric cancer via Wnt/β-catenin pathway, shedding lights on brain-type glycogen
phosphorylase as a promising therapeutic target for drug design and development targeting
gastric cancer.
