[Research Progress of DNA Methylation in Cisplatin Resistance in Lung Cancer]. [PDF]

open access: yesZhongguo Fei Ai Za Zhi, 2023
肺癌作为最常见的恶性肿瘤之一,严重威胁人类的生命健康。铂类药物如顺铂(cisplatin, DDP)是肺癌的一线治疗药物,但其获得性耐药是肺癌治疗的主要难题,也是预后不良的关键原因。顺铂耐药的发生机制较为复杂,确切机制尚未明确。大量研究表明DNA甲基化在肺癌顺铂耐药过程中发挥关键作用,DNA异常高甲基化使染色质构象发生变化,导致多种耐药基因和抑癌基因失活。阐明其复杂机制有望为寻找预测疗效的生物标志物和治疗新靶点的确定提供依据。因此,本文就DNA甲基化在肺癌顺铂耐药过程中的作用和机制做一综述 ...

DNA甲基化是人类发现的第一个表观遗传修饰,其异常变化与疾病的发生发展密切相关。针刺作为中国传统医学的重要组成,已证实其治疗疾病具有显著的疗效,针刺机制是整体性、多靶点互相影响的复杂生理病理过程,但当前针刺机制研究多是单靶点,提示需从更上游的层面研究机制。本文对证明针刺直接或间接调控DNA甲基化的研究进行综述,并探讨其在疼痛、肥胖、抑郁以及阿尔茨海默病等疾病中的作用机制,以期为针灸治疗疾病的机制研究以及针灸学科的DNA甲基化研究提供一个新的视角。未来研究应聚焦针刺对特定基因DNA甲基化影响 ...

Neighborhood disadvantage is associated with biological aging: Intervention‐induced enhancement of couple functioning confers resilience

open access: yesFamily Process, Volume 62, Issue 2, Page 818-834, June 2023., 2023
Abstract The accelerated pace of biological aging predicts mortality and morbidity later in life. The current study examines whether a change in supportive couple functioning buffers accelerated aging associated with stressful community environments among Black Americans who live in rural, Southern, disadvantaged neighborhoods.

U‐shaped association between serum IGF2BP3 and T2DM: A cross‐sectional study in Chinese population 血清IGF2BP3与2型糖尿病的U型关联:一项中国人群横断面研究

open access: yesJournal of Diabetes, Volume 15, Issue 4, Page 349-361, April 2023., 2023
Highlights This is the first cross‐sectional study of the association between serum IGF2BP3 levels and odds of T2DM in high‐risk Chinese population. Two upregulated (IGF2BP2 and IGF2BP3) and 5 downregulated (METTL3, ALKBH1, YTHDF2, YTHDF3, and HNRNPC) m6A‐related genes could contribute to the occurrence of T2DM.

Vitamin D receptor methylation attenuates the association between physical activity and type 2 diabetes mellitus: A case‐control study 维生素D受体甲基化减弱体力活动和2型糖尿病之间的联系:一项病例对照研究

open access: yesJournal of Diabetes, Volume 14, Issue 2, Page 97-103, February 2022., 2022
Highlights Vitamin D receptor (VDR) methylation attenuates the association between physical activity and type 2 diabetes mellitus (T2DM). The methylation status of the VDR promoter is associated with the secretion and sensitivity of insulin. A high physical activity level is associated with a decreased risk of T2DM compared to a low physical activity ...

DNA甲基化与2型糖尿病的相关性研究进展 Progress of the Relationship between DNA Methylation and Type 2 Diabetes

open access: yesZhongguo cuzhong zazhi, 2022
2型糖尿病是缺血性卒中最常见的危险因素之一,其发生、发展的机制尚未阐明。近年来多项研究发现,表观遗传学可以解释部分2型糖尿病相关风险。表观遗传学包括DNA甲基化、组蛋白修饰、染色质重塑、非编码RNA等,其中DNA甲基化是表观遗传学的重要组成部分,也是研究最早最广泛的机制。本文介绍了DNA甲基化在2型糖尿病相关的病理生理机制、环境因素、危险因素及并发症等方面的研究进展,探讨了DNA甲基化用于2型糖尿病预测及诊疗的临床前景,提出了通过研究DNA甲基化促进缺血性卒中一级及二级预防的可能 ...

DNA甲基化与高血压的相关性研究进展 Progress of the Relationship between DNA Methylation and Hypertension

open access: yesZhongguo cuzhong zazhi, 2023
高血压是缺血性卒中最常见的可调节危险因素之一,作为一种多病因、高度异质性的疾病,环境、遗传因素在高血压的发生、发展过程中发挥着重要作用。基因与环境之间的相互作用,也就是表观遗传修饰可能介导遗传因素、环境因素和缺血性卒中之间的关系,但具体机制仍不明确。表观遗传修饰包括DNA甲基化、组蛋白修饰、染色质重塑等,其中DNA甲基化是表观遗传的重要组成部分,也是研究相对成熟的机制。DNA甲基化可以调节基因的表达,同时也受环境因素的影响。本文介绍了DNA甲基化在高血压相关病理生理机制 ...

DNA甲基化与非大动脉粥样硬化型卒中相关性研究进展 Advances in Correlation between DNA Methylation and Non-Large Artery Atherosclerotic Stroke

open access: yesZhongguo cuzhong zazhi, 2023
缺血性卒中由多种环境因素和遗传风险因素共同决定。DNA甲基化作为一种重要的表观遗传学调控机制,可能是缺血性卒中的可遗传危险因素,对缺血性卒中的发生、发展过程产生潜在影响。缺血性卒中不同病因亚型存在特征性候选基因DNA甲基化水平改变,这对探究不同病因亚型的病理生理学过程具有重要价值。DNA甲基化是动态、可逆的表观遗传学改变,其模式可随疾病发生、发展的不同时期发生显著变化,提示DNA甲基化可作为缺血性卒中及其亚型的潜在生物标志物和治疗靶点。本文就DNA甲基化与非大动脉粥样硬化型(心源性栓塞型、小动脉闭塞型 ...

DNA甲基化与高同型半胱氨酸血症 DNA Methylation and Hyperhomocysteinemia

open access: yesZhongguo cuzhong zazhi, 2023
DNA甲基化是一种调控基因表达的表观遗传机制,由Hcy代谢相关底物S-腺苷同型半胱氨酸(S-adenosyl-L-homocysteine,SAH)依赖性的DNA甲基转移酶(DNA methyltransferases,DNMTs)催化,对维持细胞稳态至关重要。多项研究表明,高同型半胱氨酸血症(hyperhomocysteinemia,HHcy)可能通过调节甲硫氨酸-同型半胱氨酸循环(methionine-homocysteine cycle,M-H cycle)调控DNA甲基化状态 ...
