Family 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.

Journal 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.

Journal 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 ...

转突变型A53Tα-突触核蛋白基因的帕金森模型小鼠中脑的全基因组甲基化测序分析
Zhongshan Daxue xuebao. Yixue kexue ban, 2020 【目的】研究帕金森氏病（PD）致病基因SNCA在A53T位置突变后对转基因小鼠中脑多巴胺，神经元DNA甲基化修饰的影响。【方法】分别取转突变的人源α-突触核蛋白（hα-syn）即hA53Tα-syn基因小鼠和对照组小鼠的中脑组织，采用重亚硫酸盐测序法（BS-seq）分别对12月龄的转基因小鼠和非转基因（nTg）小鼠进行全基因组甲基化分析，随后筛选出差异甲基化区域（DMR）用于GO富集分析。【结果】通过对比分析，我们总计发现481个DMR，其中高甲基化与低甲基化DMR分别有257和224个 ...

The epigenetic mechanism of imprinted gene IGF2 regulated by MEN1 in hepatocellular carcinogenesis [PDF]
, 2015 原发性肝癌是肝细胞或肝内胆管上皮细胞发生的恶性肿瘤。死亡率仅次于胃癌和食道癌,其中肝细胞癌(hepatocellularcarcinoma，HCC)占原发性肝癌的90％。我们实验室围绕menin复合物调控的组蛋白甲基化与疾病发生关系开展了较系统深入的研究，证明了menin在肝细胞肝癌、非小细胞型肺癌及恶性黑色素瘤等非内分泌系统肿瘤中的重要生物学功能，阐明了menin调控组蛋白甲基化修饰的规律及机制。胰岛素样生长因子——2（insulinlikegrowthfactor2,IGF2 ...

Zhongguo shiyan zhenduanxue, 2020 DNA启动子或编码区CpG岛甲基化可通过转录抑制途径参与恶性肿瘤的发生和化疗药的耐药[1]。胞嘧啶5’位点甲基化(5-methylcytosine,5mc)是恶性肿瘤中常见的DNA甲基化位点[2]。5mc的形成是一个可逆的过程,研究显示TERT家族蛋白可将5mc进一步氧化为5-羟甲基胞嘧啶(5-hydroxymethylcytosine,5hmc),从而进入胸腺DNA合成途径[3]。恶性肿瘤,包括淋巴瘤中5hmC表达缺失预后差[4-6],提示监测5hmc表达水平有助于判断预后和疗效评估。

The molecular mechanism and biological functions regulation of P2RY1 gene in low differentiated gastric adenocarcinoma [PDF]
, 2016 摘要 背景和目的：P2RY1是细胞膜蛋白受体，ADP及其类似物可以激活该受体。近期的研究发现P2RY1与肿瘤的发生发展密切相关。位于细胞膜上的P2RY1受体在接受细胞外信号刺激后，激活下游相关信号通路，发挥相应生物学功能，继而对癌细胞的增殖、分化、凋亡等产生一系列影响。本研究目的旨在运用分子生物学方法对P2RY1在低分化胃腺癌细胞的发生发展过程中的作用与相关分子机制及其生物学功能的调控进行探索研究。 方法：首先，通过胃癌样本的甲基化芯片筛选出P2RY1基因，同时在样本中通过westen ...
