5、itive APL NB4 cells. Bestatin can not reverse the differentiation block in ATRA-resistant APL MR2cells. CD13 ligation with anti-CD13 antibody WM-15 results in phosphorylation of p38 MAPK, reduces theinhibition of Bestatin on the phosphorylation of p38 MAPK, and completely abolishes the enhancement o

6、fBestatin on ATRA-inducing differentiation in NB4 cells 2. Bestatin (600 M)-treated cells progress slowerthrough the cell cycle due to decreased rate of cell growth and the frequency of cell division. Bestatin inhibitsthe frequency of mitosis and the inherent multinuclearity in D. discoideum, and is

7、 not cytotoxic to D.discoideum cells at 0-600 M. Bestatin inhibits aminopeptidase activity in lysates of PsaA-GFP- and GFP-expressing cells by 69.39% 10.5% and 39.93% 18.7% of control, respectively 4.體內(nèi)研究 Bestatin (20 M) significantly reduces CD13 expression in diabetic mice and results a significan

Bestatin treatmentsignificantly inhibits the expression of VEGF and heparanase in diabetic mice. Intravitreal bestatin treatmentsignificantly downregulates the expression of both HIF-1 and VEGF in

9、diabetic mice retinas. Furthermore,the upregulated expression of heparanase in diabetic mice retinas is significantly inhibited by intravitrealbestatin treatment 1. Bestatin (10, 1, and 0.1mg/kg, i.p.) treatment before the antigen-potentiated humoralresponse to SRBC results in an increased number of

10、 splenocytes producing hemolytic anti-SRBC antibodies(PFC) and the 2-ME-resistant serum hemagglutinin titer (at a dose of 0.1 mg/kg). Bestatin (1 and 0.1 mg/kg)administered to mice five times on alternate days after cyclophosphamide injection does not change thesuppressive effect of the drug regardi

Total cell prot

12、ein is quantified using the Bradford assay and 1-mg/mL protein aliquots are made. Tenmicroliters of total cell protein is mixed with 290 L of substrate solution (0.1 mg/mL dithiothreitol DTT, 0.1mg/mL albumin, and 1 mM alanine-naphthylamide). Fluorometric measurements (340 nm excitation, 400nm emiss

13、ion) are made after 15 and 30 min. The slope of the line between the 15- and 30-minmeasurements is used to represent aminopeptidase activity. Total cell protein is preincubated with bestatin,amastatin, puromycin, EDTA, and/or ZnCl2 for 20 min before the fluorometric aminopeptidase assay.MCE has not
