4、ieves significant neuroprotection in Huntingtons disease flies at 10 M, improving the number ofrhabdomeres from 5.2 to 5.6 1. AK-1 is a potent, specific and cell-permeable SIRT2 inhibitor, with an IC50 of12.5 M 2. AK-1 treatment induces proteasomal degradation of the Snail transcription factor throu

5、ghinactivation of the NF-B/CSN2 pathway. Reduction in the level of Snail results in upregulation of p21, leadingto G1 arrest, slow proliferation, and slow wound-healing activity. The regulation of Snail-p21 axis by AK-1 alsooccurs in HT-29 colon cancer cells 3. Under hypoxic conditions, AK-1 increas

6、es the ubiquitination of HIF-1in a VHL-dependent manner, leading to the degradation of HIF-1 via a proteasomal pathway. Downregulationof HIF-1 expression reduces its transcriptional activity and, eventually, reduces the expression of BNIP3, oneof HIF-1 target genes, in AK-1-treated cells 4.PROTOCOLC

7、ell Assay 3 HEK293 cells are co-transfected with 3 g of pGL2-PGK1-HRE-Luc and 1 g of pCMV-galactosidaseplasmids. Twenty-four hours later, the cells are incubated under hypoxic conditions for 24 hr in the presenceof 10 M AK-1 and then lysed with luciferase cell lysis buffer. Luciferase and -galactosi

8、dase activities aremeasured using luciferin and -nitrophenyl-d-galactopyranoside, respectively, as substrates. Transfectionefficiency is normalized according to -galactosidase activity 3.MCE has not independently confirmed the accuracy of these methods. They are for reference only.REFERENCES1. Luthi
