FTO promotes the p-Tau in a TSC-mTOR-dependent manner.(A) Fto knockdown repressed the activation of the mTOR signaling in neurons isolated from 3xTg AD mice. Neurons were infected with indicated lentivirus for 48h.(B) FTO overexpression activated the mTOR signaling in neurons isolated from 3xTg AD mice. Neurons were infected with indicated lentivirus for 48 h.(C) Rapamycin represses FTO-mediated phosphorylation of Tau isolated from 3xTg AD mice. Neurons were infected with indicated lentivirus for 48 h in the presence of rapamycin(100 nM).(D) Fto knockdown increases the total level of TSC1. Neurons from 3xTg AD mice were treated as in (A).(E) FTO overexpression decreases the total level of TSC1. Neurons from 3xTg AD mice were treated as in (B).(F) Fto decreases the mRNA level of Tsc1. Neurons from 3xTg AD mice were treated as in (A) or (B). **p < 0.01
(e and f) qRT-PCR and western blot assays showed the altering expression of PTEN after transfection with miRNA mimics (miR-NC, miR-106b mimics and miR-93 mimics) or anti-miRNA (anti-miR-NC, anti-miR-106b and anti-miR-93)
Increase of MMP-13 expression by Microcystin-LR in DLD-1 and HT-29 cells. After 48 h culture with microcystin-LR, the cells were treated with RIPA lysis buffer with 1mMphenylmethylsulfonyl fluoride and protease inhibitor cocktail and the total cellular protein (40 mg/lane) was used for Western blot with a specific anti-MMP-13 antibody. The membrane was probed with an anti-GAPDH antibody to confirm equal loading.

In search for better protection for PARP, we found that Bimake protease inhibitor cocktail performed best.
Bimake Protease Inhibitor Cocktail provides protein stabilization for your protein of interest. Low-expression of protein in HCT-116 cells can also be detected clearly.
We switched to Bimake protease inhibitor cocktail – it works as well at half the price.
Bimake protease inhibitor cocktail provides the best protection for β-catenin,while Roche tablet performs poorly.
传统的蛋白酶抑制剂(E-64, AEBSF, bestatin, leupeptin and aprotinin)是不能够抑制某些去泛素化(DUB)蛋白酶(例如ATAXIN-3)的功能的。(参考文献: Neil D. Rawlings, Guy Salvesen et al. Handbook of Proteolytic Enzymes,Vol.1, 2012).
