NU7441 (KU-57788)NU7441 (KU-57788)是一种高度有效的，选择性DNA-PK抑制剂，在无细胞试验中IC50为14 nM，也会抑制 mTOR 和 PI3K，对应的IC50值分别为1.7 μM和5 μM。它可降低NHEJ的频率，而增强Cas9介导DNA剪接后发生的同源重组修复率。 |
Validation of activity and specificity of chemical inhibitors of; ATM, ATR, and DNAPK. H460 cells were treated with 1 uM camptothecin (CPT) or 20 ug/ml bleomycin for 1 h in the presence of the indicated inhibitors: DNAPK-i1—NU7026, DNAPK-i2—NU7441. MSH6, fibrillarin, and tubulin were used as loading controls.Effects of DNAPK inhibitors on its autophosphorylation in bleomycin-treated cells.

Brefeldin ABrefeldin A 作用于HCT 116细胞，抑制内酯抗生素和ATPase，作用于protein transport（蛋白转运），IC50为0.2 μM，诱导癌细胞分化和凋亡。它还能提高同源重组修复效率，是CRISPR-mediated HDR的增强剂。Brefeldin A 也是自噬和线粒体自噬的抑制剂。 |
Cells were treated with brefeldin A or manumycin A, and the resulting supernatant was collected after 48 h for exosomal preparation (lanes 1 and 2), or exosomes obtained from C81 cells were trypsin-treated or freeze/thawed (F/T) and then trypsin-treated (lanes 3 and 4). Lanes 5 and 6, input exosome controls from C81 or CEM cells, respectively. Resulting exosomes were assayed for the presence of Tax by Western blotting. |

NocodazoleNocodazole是一种微管聚合的快速可逆抑制剂，也抑制Abl， Abl(E255K)和Abl(T315I)，IC50分别为0.21 μM， 0.53 μM和0.64 μM。Nocodazole可提高CRISPR介导的同源重组效率，对增强精确的基因编辑效力具有加成作用。 |
A, HeLa cells were treated with DMSO, Taxol (100 nM for 16 h), or Nocodazole (Noco, 100 ng/ml for 16 h). Total cell lysates were probed with the indicated antibodies against Hippo components on Phos-tag SDS-polyacrylamide gels. O and * mark the non-phosphorylated and phosphorylated proteins, respectively. |

4-Hydroxytamoxifen(Afimoxifene)4-Hydroxytamoxifen是tamoxifen的活性代谢产物，是一种选择性的雌激素受体调节分子，在乳腺癌的治疗和化学疗法中应用广泛。4-HT可激活intein-Cas9突变体的靶向修饰效率。 |
CDK4/6 inhibitor resistance promotes diminished ER expression and activity. (a and b) Proliferation of MCF-7 and MR cells in the presence of different concentrations of ICI (a) or 4-hydroxytamoxifen (4-OHT) (b) was measured by the alamarBlue assay and plotted as % inhibition of proliferation against log concentration of inhibitor. Each data point represents the average value±s.d. of six replicates obtained in three independent experiments. |

SCR7SCR7 是一种特异性 DNA Ligase IV 抑制剂，其阻断非同源性末端连接(NHEJ)。在哺乳动物细胞和小鼠胚胎中，SCR7可增加利用CRISPR/Cas9进行HDR介导的基因编辑效率，最高可增强至19倍。 |
The start codon CUG of PTEN-long was mutated to AUG and PTENlong expression is significantly increased. gRNA1 and gRNA2 have similar efficiency in driving PTEN-long expression (lanes 1 and 2). Combined gRNA1 and gRNA2 (lane 3) did not enhance PTEN-long expression compared to lane 1 and 2. The ssODN is required for mutation of CTG to ATG through HDR and without which PTEN-long is not expressed (lane 4). PTEN-long cDNA cloned into pcDNA3.1 with CTG to ATG mutation was highly expressed in transfected HEK293T cells (lane 5). Lane 6 is protein ladder. Lanes 7–10 indicate that the combination of gRNA and ssODN is required to facilitate HDR occurrence and double-strand DNA break. |
