Sodium butyrate with UCN-01 has marked antitumour activity against cervical cancer cells.

2010

The effect of combining sodium butyrate (NaB), a histone deacetylase inhibitor, and 7-hydroxy-staurosporine (UCN-01) on cytotoxicity in human cervical carcinoma cells was evaluated.HeLa and CaSki cells were treated using NaB alone or in combination with staurosporine (STS) or its analog UCN-01. Cytotoxicity was determined by flow cytometry and morphological assays. Apoptotic pathways were characterized by Western blotting and immunostaining. CaSki cells were also xenografted into nude mice to assess the in vivo effects of NaB/UCN-01 combination.Treatment with NaB and STS or UCN-01 resulted in enhanced apoptosis of cancer cells. Apoptosis involved mitochondrial pathways and overexpression of…

Differential inhibition of TRAIL-mediated DR5-DISC formation by decoy receptors 1 and 2.

2006

International audience; Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF family that induces cancer cell death by apoptosis with some selectivity. TRAIL-induced apoptosis is mediated by the transmembrane receptors death receptor 4 (DR4) (also known as TRAIL-R1) and DR5 (TRAIL-R2). TRAIL can also bind decoy receptor 1 (DcR1) (TRAIL-R3) and DcR2 (TRAIL-R4) that fail to induce apoptosis since they lack and have a truncated cytoplasmic death domain, respectively. In addition, DcR1 and DcR2 inhibit DR4- and DR5-mediated, TRAIL-induced apoptosis and we demonstrate here that this occurs through distinct mechanisms. While DcR1 prevents the assembly of the…

Use of CDC2 from etoposide-treated cells as substrate to assay CDC25 phosphatase activity

1999

International audience; Cyclin-dependent kinases (CDKs) regulate the key transition of the cell cycle in all organisms. In response to Etoposide (VP-16) induced DNA damage, cells undergo a G2-phase arrest resulting in the accumulation of inactive CDK1 (CDC2) kinase complexes. Here we report that upon Etoposide treatment CDC2 is phosphorylated on tyrosine 15 and is dephosphorylated and activated in vitro by recombinant CDC25 phosphatase. We also show that inactive CDC2 kinase from Etoposide-treated cells can be used as a substrate in a sensitive two-step assay of CDC25 phosphatase. This assay, which is very simple to set-up, is based on the monitoring of CDC2 kinase activity after CDC25-depe…
