FABP4 and cancer: Such pseudohypoxia states may lead to neovascularization, as was suggested by using an A”D model [138], and malignant tumors [139,140], and this scenario may strongly support our observations, indicating that FABP4 is an independent key pathogenic factor for RVDs [12] such as DR [10] and RVO [9] in addition to intraocular physiology.
