Consistent with findings reported in previous studies, variations in the retinoic acid degrading enzyme Cyp26b1 (31), macrophage capping protein CapG (32), calcium-activated potassium channel protein KCNN4 (33), VAMP-8 (17), and leukemia inhibitory factor (LIF) (34) confirmed the accuracy of the RNA-seq results, suggesting that MC degranulation might expedite the progression of ovarian cancer. Here, CYP26B1 is linked to ovarian cancer.
