An exploration of GuaLouQuMaiWan related novel prognostic model and search for potential compound pachymic acid in bladder cancer

Objective: Bladder cancer (BC) is a highly prevalent malignant tumor. The traditional Chinese medicine formula Guo Lou Qu Mai Wan (GLQMW), when used in conjunction with chemotherapy, has been shown to reduce adverse reactions and prolong survival time, although its specific mechanisms remain unclear. This study aims to investigate whether GLQMW exerts its therapeutic effects on bladder cancer by modulating the tumor immune microenvironment. Methods: To elucidate the molecular mechanisms of GLQMW, we employed bioinformatics analysis, systems pharmacology, and molecular docking to explore the prognostic value of GLQMW-related target genes for BC and to establish a prognostic prediction model. We analyzed the relationship between GLQMW-related target genes and immune cell infiltration, as well as the compositional differences of immune cell subpopulations across different risk groups. Molecular docking was used to screen for pachymic acid (PA) as the main anticancer active compound, and CCK8 and western blot were used to determine the target of PA as the active compound. Result: . Conclusions: PA, the active ingredient of GLQMW, can inhibit BC by inhibiting EGFR and upregulating FABP6.
