AGING CELL:新早衰治疗靶标被发现

2018-09-17 海北 MedSci原创

Hutchinson-Gilford早衰综合征(HGPS)是一种致命的早衰,病人会表现出多个和正常的衰老特征相似的表型。这种疾病是由LMNA基因突变导致的,其能产生progerin,引起畸形细胞核,进而引起细胞衰老和衰老。已有的研究显示,磷脂酶A2受体(PLA2R1)促进复制,氧化和致癌应激诱导的衰老,但它在progerin诱导的衰老和早衰中的作用目前尚不清楚。最近,研究人员发现,PLA2R1的敲

Hutchinson-Gilford早衰综合征(HGPS)是一种致命的早衰,病人会表现出多个和正常的衰老特征相似的表型。这种疾病是由LMNA基因突变导致的,其能产生progerin,引起畸形细胞核,进而引起细胞衰老和衰老。
已有的研究显示,磷脂酶A2受体(PLA2R1)促进复制,氧化和致癌应激诱导的衰老,但它在progerin诱导的衰老和早衰中的作用目前尚不清楚。
最近,研究人员发现,PLA2R1的敲低能够防止人成纤维细胞中progerin表达诱导的衰老,并显着延迟了HGPS患者衍生的成纤维细胞的衰老。在早衰小鼠模型中Pla2r1的全身敲除减少了一些早衰表型,例如肋骨骨折和骨含量降低,以及衰老标记物减少。与对照相比,表达Progerin的人成纤维细胞表现出高频率的畸形细胞核和增加的法呢基二磷酸合成酶(FDPS)表达; PLA2R1的敲低降低了畸形核的频率,并使FDPS表达正常化。
PPSidronate是一种FDPS抑制剂,也可以减少衰老和畸形细胞核。在PLA2R1的下游,研究人员发现p53介导了progerin诱导的FDPS表达和畸形细胞核的增加。
这些结果表明PLA2R1通过p53 / FDPS途径介导关键的早衰表型,可能是一种新的治疗靶点。

导致卵巢早衰的十大元凶!

卵巢早衰是指妇女在初潮以后到40岁以前由于卵巢功能衰退而引起月经失调、性欲减退、性功能降低、不孕、围绝经期综合征等一系列症状的疾病。其特征是卵巢内无卵母细胞或虽有原始卵泡,但对促性腺激素无反应,表现为低雌激素(E2) <25 ng/L和高促性腺激素状态。卵巢早衰让年轻女人不再“年轻”。虽然目前对卵巢早衰的具体病因尚未完全阐明,但国内外诸多研究发现有很多环境或医源性因素会促进卵巢的发生,如
