Abstract
Objectives
This study aimed to investigate oxidative stress markers in the oral mucosal cells of individuals diagnosed with major depressive disorder (MDD).
Methods
A case-control design was used, including twenty patients diagnosed with MDD, based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria, and twenty healthy controls. Oral exfoliated cells were collected from all participants. Intracellular levels of reactive oxygen species (ROS), mitochondrial membrane potential (ΔΨm), caspase-3 and -7 activity, and reduced glutathione (GSH) were measured in Arbitrary Fluorescence Units (AFU).
Results
The MDD group demonstrated significantly elevated intracellular ROS levels (p = 0.0012) and caspase-3 and -7 activity (p = 0.0171) in comparison to the control group. Additionally, a decrease in ΔΨm expression was observed in the oral cells of MDD patients (p = 0.0265), whereas GSH expression levels did not differ significantly between the two groups (p = 0.8908).
Conclusions
The findings indicate heightened oxidative stress in the oral exfoliated cells of individuals with MDD. This study supports the potential use of oral cells as a non-invasive biomarker source for assessing oxidative stress in depressive disorders.
期刊介绍:
Journal of Oral Biology and Craniofacial Research (JOBCR)is the official journal of the Craniofacial Research Foundation (CRF). The journal aims to provide a common platform for both clinical and translational research and to promote interdisciplinary sciences in craniofacial region. JOBCR publishes content that includes diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the mouth and jaws and face region; diagnosis and medical management of diseases specific to the orofacial tissues and of oral manifestations of systemic diseases; studies on identifying populations at risk of oral disease or in need of specific care, and comparing regional, environmental, social, and access similarities and differences in dental care between populations; diseases of the mouth and related structures like salivary glands, temporomandibular joints, facial muscles and perioral skin; biomedical engineering, tissue engineering and stem cells. The journal publishes reviews, commentaries, peer-reviewed original research articles, short communication, and case reports.
