用于检测、定量和定位抗原与抗体的技术——ELISA、免疫印迹、免疫组化与流式细胞术。以下是我们知识库中标注该主题的实验方案、常见问题与技术文章。
MTAP loss disrupts the methionine salvage pathway, resulting in the accumulation of 5′-methylthioadenosine (MTA) and partial inhibition of PRMT5 activity. Cancer cells consequently enter a state with limited PRMT5 functional reserve and develop greater dependence on residual PRMT5 activity and ...
MTAP缺失可阻断甲硫氨酸补救代谢，使5′-甲硫腺苷（MTA）积累并部分抑制PRMT5活性。癌细胞由此进入PRMT5功能余量降低的状态，对剩余PRMT5活性及SAM供应形成更强依赖，使MTAP缺失成为可利用的肿瘤代谢脆弱性。
MAT催化甲硫氨酸与 ATP 生成 S-腺苷甲硫氨酸（SAM），而 SAM 既是细胞内最核心的活性甲基供体之一，又处于一碳代谢、表观遗传调控和应激适应的交汇位置。随着 MAT1A/MAT2A 同工酶切换、MTAP 缺失相关 MAT2A 依赖以及 PRMT5 轴耦合机制逐步明确，MAT-SAM ...
MAT catalyzes the conversion of methionine and ATP into S-adenosylmethionine (SAM). SAM is not only one of the most central active methyl donors in cells, but also lies at the intersection of one-carbon metabolism, epigenetic regulation, and stress adaptation. As mechanisms involving MAT1A/MAT2A ...
