COL13A1 and glaucoma: Regarding core ECM genes that were significantly altered only in CAβ3 cells, neither VWA5A (FC = 2.67) nor COL13A1 (FC = −1.64) have been found to be associated with glaucoma, although COL13A1 was differentially regulated in response to the steroid triamcinolone in cultured HTM cells [61].
