PARP and PARG inhibitors in cancer treatment - PubMed
2020年3月1日 · Inhibitors of poly(ADP-ribose) glycohydrolase (PARG) exploit and exacerbate replication deficiencies of cancer cells and may complement PARP inhibitors in targeting a broad range of cancer types with different sources of genomic instability. Here I provide an overview of the molecular mechanisms and cellular consequences of PARP and PARG ...
靶向DNA修复途径治疗肿瘤的机制及临床应用 - 健康界
2022年4月21日 · parp抑制剂是brca突变肿瘤的一种很有前途的治疗策略。 聚adp-核糖水解酶(parg)抑制剂. parg通过在dna损伤后水解par核糖键来逆转parp酶的作用。同样,parg在dna复制和修复中的积极作用导致parg缺陷细胞对dna损伤剂的敏感性增加。
Poly (ADP-Ribose) Glycohydrolase (PARG) vs. Poly (ADP-Ribose ...
2020年8月28日 · The therapeutic potential of targeting PARylation using PARP or PARG inhibitors alone or in combination with other therapies clearly has promise as an anti-cancer therapy. However, genetic manipulation of PARP and PARG suggests that PAR levels can also impact tumor induction and progression.
Selective small molecule PARG inhibitor causes replication fork ...
2019年12月11日 · Poly (ADP-ribose)ylation (PARylation) by PAR polymerase 1 (PARP1) and PARylation removal by poly (ADP-ribose) glycohydrolase (PARG) critically regulate DNA damage responses; yet, conflicting...
PARP and PARG inhibitors in cancer treatment - PMC
PARP inhibitors act through synthetic lethality with mutations in DNA repair genes and were approved for the treatment of BRCA mutated ovarian and breast cancer. PARP inhibitors destabilize replication forks through PARP DNA entrapment and induce cell death through replication stress-induced mitotic catastrophe.
“合成致死”新靶点,中国首个PARG抑制剂在美获批临床_生命科学_ …
2024年6月25日 · 据该公司介绍,dat-2645是丹擎医药自主研发的一种全新结构的、高选择性的口服小分子聚adp核糖水解酶(parg)抑制剂。 PARG与多聚ADP核糖聚合酶(PARP)作用于相同的信号通路,在DNA损伤修复应答和DNA复制过程中起关键作用。
蛋白质的ADP-核糖化修饰 - 知乎 - 知乎专栏
2021年1月7日 · 负责清除ADPR修饰的eraser包括多种水解酶,如ADP-核糖基水解酶3(ARH3)、PAR糖水解酶(PARG)、TARG / C6orf130、MacroD1和MacroD2以及NUDIX水解酶家族等。 这些eraser作用方式不同,PARG和ARH3催化PAR链断裂,保留末端ADP-核糖部分;NUDIX水解酶家族保留磷酸核糖部分; TARG ...
聚(ADP-核糖)糖水解酶(PARG)与聚(ADP-核糖)聚合酶(PARP…
聚(adp-核糖)糖水解酶(parg)逆转parp酶的作用,水解聚(adp-核糖)中存在的核糖-核糖键。 像PARPs一样,PARG参与DNA复制和修复,PARG耗尽/抑制的细胞对DNA损伤剂的敏感性增加。
Poly (ADP-Ribose) Glycohydrolase (PARG) vs. Poly (ADP-Ribose ...
2020年8月28日 · Poly(ADP-ribose) glycohydrolase (PARG) reverses the action of PARP enzymes, hydrolysing the ribose-ribose bonds present in poly(ADP-ribose). Like PARPs, PARG is involved in DNA replication and repair and PARG depleted/inhibited cells show increased sensitivity to DNA damaging agents.
PARP、PARG
Poly (ADP-ribose) glycohydrolase (PARG) 是多聚 ADP-核糖水解酶的主要成员之一。 爱思益普针对 PARP 家族和 PARG 也设计并验证了一系列生化合细胞学的实验来助力化合物的筛选。
