Somatic mutations(SMs)accumulate over the lifetime of cells and can lead to cancer and other diseases;however,SMs can be difficult to detect,especially when they are present in very few cells.In a recent Nature paper,Abascal et al.develop a protocol capable of detecting SMs present on only a single molecule of DNA and apply it to both mitotic and post-mitotic human tissues.

动物性食品中脂肪含量的多少及脂肪酸的组成已成为衡量动物性食品质量的主要因素.脂肪含量的多少由脂肪细胞数量的多少和体积的大小共同决定,脂肪细胞凋亡也会直接导致脂肪细胞数量的减少.CLAs(conjugated linoleic acids)是一类含有共轭双键的十八碳二烯酸同分异构体的统称,其活性形式c9,t11-CLA和t10,c12-CLA能够通过调控多种与脂肪生成有关的核转录因子的表达、脂肪酸的摄取、氧化及脂肪的合成来调节脂肪细胞的发育过程进而降低机体脂肪含量,改变脂肪酸组成,改善肉质.该文对CLAs在
中国云南省宣威市是肺部疾病(特别是肺癌和慢性阻塞性肺病)的高发区域,并且其女性肺癌的死亡率居全国首位,因此了解该地区肺癌高发的原因对当地居民尤为重要.肺癌的发生往往是环境与遗传因素共同作用的结果,该地区长期以烟煤为生活燃料,烟煤燃烧和吸烟都会释放大量的多环芳烃(polycyclic aromatic hydrocarbons,PAHs).PAHs在机体内的代谢过程涉及到多种毒物代谢酶的作用,而毒物代谢酶的基因多态性会影响个体对肺癌的易感性.该文的目的 在于探究多环芳烃在机体内的代谢、毒物代谢酶基因的多态性
肥胖症是脂肪过度堆积引起的一类代谢症群,其患病率在全球范围内呈上升趋势.肥胖与代谢性疾病和癌症密切相关,因此了解脂肪形成的过程以及影响脂肪生成的分子机制至关重要.m6A修饰是大多数真核生物最普遍和含量最丰富的mRNA修饰,可以调节mRNA代谢的多个方面,包括mRNA的稳定性、翻译、加工、剪接、转运和降解等.m6A修饰作为动态可逆的转录后修饰,参与胚胎发育、精子发生、DNA损伤、组织稳态等生理过程,对脂肪形成也有调控作用.该综述通过总结最近的研究,概括了m6A修饰对脂肪生成的影响,这有助于研究者从转录后水平
造血干细胞移植(HSCT)是高危恶性血液疾病和遗传等其他因素危及造血系统疾病的有效治疗手段.然而,移植物抗宿主病(GVHD)影响了其广泛应用.肠道微生物(G]Ⅵ)多样性稳.态的维持和相关代谢产物可促进机体新陈代谢、抵御病原体入侵和调节免疫系统,从而对宿主健康和疾病产生影响.异基因造血干细胞移植(allo-HSCT)患者在受到药物和外源细胞处理时,其体内的免疫系统和肠道微生物之间的动态平衡更容易被破坏,由此会继发肠道炎症和GVHD.因此,GM不仅可作为移植后死亡率的独立预测指标,还可靶向肠道微生物,通过营养
