Graphical abstract The hypoxia microenvironment induces the expression of HIF1 and EPAS1 in GCA. During tumor development, the EPAS1 suppresses the expression of HIF1, resulting in the dominant form of HIFs switching from HIF1 to EPAS1. LncRNA ZFAS1 binds to EPAS1, facilitating the HIF1 suppression, EPAS1 up-regulation, and the switching from HIF1 to EPAS1.
