皮肤黑色素瘤的发病率和死亡率存在性别差异,随着年龄的增长和在男性中不成比例。然而,潜在的机制仍不清楚。虽然已经评估了肿瘤细胞的生物性别差异和固有免疫反应变异性,但肿瘤周围微环境在衰老过程中的作用一直被忽视。
造血干细胞和祖细胞(hematopoietic stem and progenitor cell, HSPC)一生都在制造成熟的血细胞 ... 作用是由HSPC表面的“吃我”信号——钙网蛋白(calreticulin, Calr)介导的。活性氧(ROS)水平较高的造血干细胞表面Calr水平会升高,这会触发巨噬细胞吞噬并杀死含有大量 ...
These cells deploy complex cytoskeletal rearrangements to recognize and eliminate potential threats 3. Even in the steady state, myeloid cells constantly survey their surroundings for potential ...
根毛是从根表皮细胞分化而来的管状突起,是植物根系的重要组分。由于根毛的形成大大增加了根系的表面积,因此普遍认为根毛对植物获取土壤中的水分和磷素营养十分重要。在模式植物拟南芥中,根毛发育机理被广泛研究。根毛的形成受特定的转录因子模块控制,同时也受到多种 ...
2024 年 9 月 12 日, Nature Chemical Biology 在线发表了赵忠教授团队题为 Control of DNA demethylation by superoxide anion in plant stem cells 的最新研究成果,解析了超氧根信号传递和决定真核生物干细胞命运的分子机制 ...
FAO is catalyzed by the mitochondrial trifunctional protein (MTP) and, if overloaded, generates ROS. ROS are boosted during ...
皮肤黑色素瘤是一种恶性肿瘤,其发病率和死亡率存在明显的性别差异,尤其在老年男性中更为显著。尽管之前的研究已经评估了肿瘤细胞本身和免疫反应的性别差异,但关于肿瘤微环境在衰老过程中所扮演的角色,尤其是性别特异性的影响,一直缺乏深入探讨。
“Copper also helps protect cells from harmful molecules termed reactive oxygen species, or ROS, which in excess can damage proteins and DNA, ultimately driving cell death, including neurons that die ...
New therapeutic opportunities often emerge from research on simple organisms. For instance, the 2020 Nobel Prize in Chemistry ...
