"Flow cytometry and immunofluorescence microscopy reveal that CYLD increases the ability of noscapine to induce mitotic arrest and apoptosis."

reach
"Based on the data presented in this work, we propose the following model for how CYLD promotes noscapine activity in leukemia cells."

reach
"We found that CYLD, but not its DeltaCG1 mutant, significantly promoted the effect of noscapine on microtubule assembly in vitro."

reach
"CYLD enhances noscapine activity to induce mitotic arrest and apoptosis in a microtubule dependent manner."

reach
"Examination of cellular microtubules as well as in vitro assembled microtubules shows that CYLD enhances the effect of noscapine on microtubule polymerization."

reach
"Immunofluorescence microscopy also showed that CYLD and its C/S mutant, but not its DeltaCG1 mutant, increased noscapine activity to cause mitotic arrest."

reach
"XREF_BIBR, XREF_BIBR, XREF_BIBR, XREF_BIBR, XREF_BIBR CYLD has also been shown to stimulate noscapine activity in acute lymphoblastic leukemia via a microtubule dependent mechanism."

reach
"CYLD enhances the effect of noscapine on microtubule polymerization."

reach
"Thus, we examined whether CYLD modulates the ability of noscapine to cause mitotic arrest."

reach
"In addition, flow cytometric analysis of DNA content showed that CYLD and its C/S mutant, but not its DeltaCG1 mutant, promoted the ability of noscapine to induce the accumulation of G2/M cells."

reach
"To understand how CYLD modulates noscapine activity in leukemia cells, we transfected cells with GFP, GFP-CYLD, GFP-CYLD-DeltaCG1, in which the extreme N-terminal CAP-Gly domain of CYLD was deleted, or GFP-CYLD-C/S, in which cysteine 601 was mutated to serine to disrupt the deubiquitinase activity of CYLD."

reach
"It is possible that CYLD may also exert on these pathways to stimulate noscapine activity."

reach
"Here we demonstrate that cylindromatosis (CYLD), a microtubule associated tumor suppressor protein, modulates the activity of noscapine both in cell lines and in primary cells of acute lymphoblastic leukemia (ALL)."

reach
"Collectively, these results suggest that CYLD stimulates noscapine activity to promote microtubule polymerization, without affecting microtubule nucleation."

reach
"These data indicate that CYLD increases the effect of noscapine on microtubule polymerization."
