生物活性

MG-132是一种蛋白酶体抑制剂,IC50为100 nM,也抑制钙蛋白酶,IC50为1.2 μM。MG132通过诱导细胞周期停滞以及引发细胞凋亡来抑制HeLa细胞的生长。MG-132 (10 μM) 通过抑制蛋白酶体介导的IκBα降解,有效抑制A549细胞中TNF-α诱导的NF-κB活化。MG132可以抑制NLRP1的活化。

体内研究中,MG-132(ip,0.1 mg/kg/day)通过调节ERK1/2和JNK1信号通路,减轻压力超负荷引起的心脏肥大。MG-132治疗通过下调肌肉特异性泛素连接酶atrogin-1/MAFbx 和MuRF-1 mRNA,显著减少小鼠体内固定化诱导的骨骼肌萎缩。

实验结果 As shown above, GST-Nup53 was immobilized on glutathione sepharose beads (Figure 21A, load, bottom lane; Coomassie blue stained gel) and incubated with equal amounts of CP or Blm10-CP. To confirm that equal amounts of proteasome were used, the loads were separated by SDS-PAGE, and the gel was subsequently stained with Coomassie blue and immunoblotted against the HA-tag of 4 (Figure 21A, load).

实验结果 In fact, our data obtained in the presence of MG132 and/or cycloheximide (Fig. 4 and 5) indicated that CFTR synthesis may also be affected by PsaDM. Our study, as well as data from the literature, thus indicated that P. aeruginosa exoproducts may impact CFTR protein synthesis, degradation and trafficking/recycling to the cell membrane.

实验结果 To confirm that the huge accumulation of CFTR protein observed after proteasomal inhibition with MG132 (MG132+LB at 18 h) (fig. 5a and b) was secondary to newly synthesised CFTR proteins, we verified that a co treatment with CHX (MG132+CHX+LB) totally prevented CFTR accumulation.

实验结果 Results showed that NH4Cl, but not MG132, 3-MA or wortmannin, induced the accumulation of HSD17B4 protein (Fig. 2A ), indicating that the degradation of HSD17B4 is independent of the proteasome and macroautophagy pathways.

细胞系 Lung cancer cell lines A549 and H1299
方法 Cell viability assay. Cell viability was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Cells were seeded in 96-well plates at a density of 2.5x103/well 1 day prior to treatment. Then, cells were treated with MG132 or/and irradiation. After treatment, 20 µl of 5 mg/ml MTT solution was added into each well and incubated for 4 h. After the supernatant was removed, 100 µl of DMSO was added, and then placed in a microplate reader to measure OD value. Cell viability rate (vR) was calculated according to the following formula: vR = (OD in observed group/OD in 0 Gy group) x 100%. All assays were repeated 3 times in quintuplicate.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
