Microglial Iron Trafficking: New Player In Brain Injury, Elif Keles, Hasan Hüseyi̇n Kazan, Lati̇fe Arzu Aral, Hayrunni̇sa Bolay Belen

Turkish Journal of Medical Sciences

Neonatal brain injury is a significant reason of neurodevelopmental abnormalities and long-term neurological impairments. Hypoxic-ischemic encephalopathy and preterm brain injury, including intraventricular hemorrhage are the most common grounds of brain injury for full-term and preterm neonates. The prevalence of hypoxic ischemic encephalopathy varies globally, ranging from 1 to 3.5/1000 live births in high-resource countries and 26/1000 in low-resource countries. Preterm birth's global incidence is 15 million, a significant reason for infant mortality and morbidity, permanent neurologic problems, and the associated social and economic burden. The widespread neurodevelopmental effects of neonatal brain injury could have an unfavorable impact on a variety …

Turkish Journal of Medical Sciences

Background/aim: NLRP3 inflammasome activation has been known to be involved in the etiology and progression of Alzheimer?s disease (AD). Furthermore, AD and diabetes mellitus have common pathomechanisms. It has been shown that P2X7R whose expression is increased in brain tissues with AD and plays a role in the activation of NLRP3 inflammasome is suppressed by miR-373 in patients with osteoarthritis. Therefore, the question of whether the suppressive effect of miR-373 on NLRP3 may have a role in the pathophysiology of AD comes to mind. On the other hand, it is known that the miR-204 level increases in response to TXNIP, …

The Role Of Pericytes On The Efficacy Of Bevacizumab In Colorectal Cancer, Merve Besler, Fatma Sena Dost, Fi̇li̇z Çay Şenler, Bi̇lge Ayça Kirmizi, Berna Savaş, Hakan Akbulut

Turkish Journal of Medical Sciences

Background/aim: Pericytes are mesenchymal cells surrounding capillary vessels and are known to play an essential role in tumor angiogenesis. Chondroitin sulfate proteoglycan 4 (CSPG4) is a cell surface proteoglycan and its release from pericytes and vascular smooth muscle cells is very important in tumor angiogenesis. Bevacizumab, which is a monoclonal antibody frequently used in the treatment of metastatic colorectal cancer, binds to the ligand of vascular endothelial growth factor A (VEGFA) and inhibits tumor angiogenesis. However, no reliable biomarker for predicting patients that will show a good response to this therapy has been established yet. In this study, we aimed …
