遺伝子研究の概要
Ptgis, also known as prostaglandin I2 synthase, is a member of the cytochrome P450 family. It catalyzes the isomerization of prostaglandin H2 to prostacyclin, a potent vasodilator and inhibitor of platelet aggregation [9]. PTGIS is involved in metabolic pathways, arachidonic acid metabolism, steroid biosynthesis, and cancer pathways [3]. It also plays a role in fatty acid metabolism [2,6].
In patients with idiopathic pulmonary arterial hypertension (IPAH), rare loss-of-function variants in PTGIS were identified. These variants were associated with increased susceptibility to IPAH and a more significant pulmonary vascular response to iloprost, indicating a role in IPAH pathogenesis [1]. In endometriosis, hypoxia-hindered methylation of PTGIS in endometrial stromal cells accelerates the disease progression by inducing CD16-NK-cell differentiation [4]. In prostate cancer, rsRNA-28S regulates chemoresistance by targeting PTGIS [5]. In endometrial cancer, PTGIS affects the malignant biological behavior of the cancer cells [6]. In lung squamous cell carcinoma, PTGIS promotes cancer cell proliferation, migration, and invasion [7]. In liver fibrosis, DNA methylation of PTGIS enhances hepatic stellate cells activation and fibrogenesis, while overexpression of PTGIS inhibits this activation [8].
In conclusion, PTGIS is crucial in multiple biological processes and disease conditions. Its role in regulating prostacyclin production affects various physiological functions. Studies, especially those on loss-of-function variants and methylation-related changes, have revealed its significance in diseases like IPAH, endometriosis, and multiple types of cancer, providing potential therapeutic targets for these diseases.
