Searching for Biomarkers in Proliferative Diabetic Retinopathy: Amphiregulin and Progranulin.
Objective: Diabetic retinopathy is a common diabetic microvascular problem. Its diagnosis and classification are based on visible changes in clinical fundus examination. However, the discovery of possible vitreous biomarkers in patients with proliferative and nonproliferative diabetic retinopathy may guide both the differentiation and degree of retinopathy. Biomarkers that will be accepted can be also a treatment target. Amphiregulin (AREG) promotes proliferative and regenerative activity and repairs most cell types by binding and activating epidermal growth factor receptors. Progranulin (PGRN) has complex functions in many physiological and pathological processes. Thus, this study aimed to report vitreous AREG and PGRN levels in patients with diabetes and proliferative retinopathy and compare the results with those without diabetes.
Methods: Thirty-three eyes of 33 patients with proliferative diabetic retinopathy and 31 eyes of 31 patients without diabetes were included in this study. Vitreous humor samples were collected from all patients at the time of pars plana vitrectomy surgery immediately before the surgical procedure. Vitreous AREG and PGRN values were determined by the ELISA method.
Results: The mean AREG and PGRN values were similar in the groups (p=0.427, p=0.459, respectively).
Conclusions: The results demonstrated that vitreous AREG and PGRN levels have no significant relationship with proliferative diabetic retinopathy.
期刊介绍：
The Medeniyet Medical Journal (Medeniyet Med J) is an open access, peer-reviewed, and scientific journal of Istanbul Medeniyet University Faculty of Medicine on various academic disciplines in medicine, which is published in English four times a year, in March, June, September, and December by a group of academics. Medeniyet Medical Journal is the continuation of Göztepe Medical Journal (ISSN: 1300-526X) which was started publishing in 1985. It changed the name as Medeniyet Medical Journal in 2015. Submission and publication are free of charge. No fees are asked from the authors for evaluation or publication process. All published articles are available online in the journal website (www.medeniyetmedicaljournal.org) without any fee. The journal publishes intradisciplinary or interdisciplinary clinical, experimental, and basic researches as well as original case reports, reviews, invited reviews, or letters to the editor, Being published since 1985, the Medeniyet Med J recognizes that the best science should lead to better lives based on the fact that the medicine should serve to the needs of society, and knowledge should transform society. The journal aims to address current issues at both national and international levels, start debates, and exert an influence on decision-makers all over the world by integrating science in everyday life. Medeniyet Med J is committed to serve the public and influence people’s lives in a positive way by making science widely accessible. Believing that the only goal is improving lives, and research has an impact on people’s lives, we select the best research papers in line with this goal.
