General description

The human p27Kip1 C-terminus PIM-1 phosphorylation site- (Thr198) containing sequence is synthesized with an N-terminal Arg octamer/R8-containing sequence to facilitate its use as a cell-permeable, substrate-competitive PIM-1 inhibitor. Reported to completely prevents human prostate carcinoma DU145-derived tumor expansion for up to 17 days (0.5 µmol/animal on days 0 & 5; intratumoral injection) in mice in vivo when combined with a single Taxol (Cat. No. 580555) dosage on day zero (60 mg/kg; i.p.). Studies using FITC-conjugated R8-T198wt demonstrate that R8-T198wt-induced cell cycle arrest and apoptosis in PIM-1-expressing DU145 cells are direct consequences of inhibition of PIM-1-mediated p27Kip1 Thr198 and Bad Ser112 phosphorylation, respectively.
The human p27Kip1 C-terminus PIM-1 phosphorylation site- (Thr198) containing sequence is synthesized with an N-terminal Arg octamer/R8-containing sequence to facilitate its use as a cell-permeable, substrate-competitive PIM-1 inhibitor. Reported to retard human prostate carcinoma DU145-derived tumor growth in mice (100% vs 257% tumor growth on day 14 with or without 0.5 µmol/animal dosing on days 0 & 3; intratumoral injection) in vivo and completely prevents tumor expansion for up to 17 days (0.5 µmol/animal on days 0 & 5; intratumoral injection) when combined with a single Taxol (Cat. No. 580555) dosage (60 mg/kg; i.p.) on day zero. Studies using FITC-conjugated R8-T198wt confirms cellular delivery and PIM-1 interaction (KD = 323 nM), demonstrating also that R8-T198wt-induced cell cycle arrest and apoptosis in PIM-1-expressing DU145 cells are direct consequences of inhibition of PIM-1-mediated p27Kip1 Thr198 and Bad Ser112 phosphorylation, respectively.
