Abstract

BACKGROUND: Aging is an unavoidable part of life, defined by a gradual loss in tissue and organ function and an increasing chance of death. Current studies of aging connected the genetic and epigenetic changes to cause this process.CONTENT: When the aging-related epigenetic alterations is accumulated, it may result in irregulated gene expression, metabolic instability, stem cell senescence and exhaustion, and imbalance of tissue homeostasis, which all accelerate the aging process. Altered epigenetic gene regulatory mechanisms  such as DNA methylation,  histone modification and chromatin remodeling, and non-coding RNAs can induce aging process, thus manipulating these processes give a chance for the success of age-delaying interventions.SUMMARY: Given updated tools and technologies to investigate the epigenetic regulation affecting aging processes, new therapeutic strategies to delay this process can be developed to increase longevity and improve quality of life.KEYWORDS: aging, epigenetic, senescence, autophagy, mitochondria, metabolism, rejuvenation

Abstract

BACKGROUND: Active mucosal chronic otitis media (COM) is prevalent in lower-income countries and is associated with recurrent episodes of otorrhea due to chronic inflammation of the middle ear. Cytokines, which are well-known for their effects on the immune system, play an important role in the inflammatory response and tissue remodeling. The specific contributions of proinflammatory and immunoregulatory cytokines in the pathophysiology of active mucosal COM remain unclear. This study aimed to compare the levels of serum tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β in patients with active mucosal COM vs. healthy subjects.METHODS: Total 20 subjects with active mucosal COM and 20 healthy subjects participated in this study. The levels of serum TNF-α and TGF-β were measured using enzyme-linked immunosorbent assay (ELISA).RESULTS: The average level of serum TNF-α in subjects with active mucosal COM was significantly higher compare to the healthy subjects (46.373±41.76 pg/mL vs. 15.021±7.16 pg/mL; p=0.004). In contrast, the average level of serum TGF-β in subjects with active mucosal COM was lower compared to the healthy subjects, although the difference is not statistically significant (9.963±3.2 ng/mL vs. 11.78±8.48 ng/mL; p=0.552). Further analysis showed that in subjects with active mucosal COM, the levels of serum TNF-α had a medium positive correlation with the level of TGF-β (r=0.525; p=0.018).CONCLUSION: TNF-α and TGF-β, which are proinflammatory and immunoregulatory cytokines, may contribute to the pathogenesis of recurrent episodes of otorrhea in an active mucosal COM.KEYWORDS: tumor necrosis factor-α, transforming growth factor-β, active mucosal chronic otitis media

Abstract

BACKGROUND: Inflammation occurs in chronic diseases such as type 2 diabetes mellitus (DM). Insulin resistance and inflammation in type 2 DM with obesity can increase interleukin (IL)-6, causing an increase in hepcidin synthesis in the liver. Increased inflammation can exacerbate the course of type 2 DM. This study aims to prove that there are differences in the levels of hepcidin and IL-6 between obese and non-obese type 2 DM.METHODS: This cross-sectional study was conducted on 61 patients with type 2 DM, consist of 22 male and 39 female with an age of more than 40 years. Type 2 DM subjects were obtained from a doctor's diagnosis and were divided into obese and non-obese groups based on body mass index (BMI). Hepcidin and IL-6 levels were examined using the Enzyme-Linked Immunosorbent Assay (ELISA) principle. The data were analyzed using an independent t-test and Mann-Whitney test.RESULTS: The mean level of hepcidin in the obese with type 2 DM group was 25.32±11.54 ng/mL, and non-obese was 11.94±5.31 ng/mL. The median level of IL-6 in the obese with type 2 DM group was 11.9 (5-61) pg/mL, and non-obese 4.8 (1.5-9.8) pg/mL. There was a significant difference in hepcidin and IL-6 levels between the obese and non-obese groups (p=0.000).CONCLUSION: Hepcidin and IL-6 levels in the obese group with type 2 DM were higher than non-obese group.KEYWORDS: type 2 diabetes mellitus, obesity, hepcidin, interleukin-6
