A t(1;19)(q10;p10) mediates the combined deletions of 1p and 19q and predicts a better prognosis of patients with oligodendroglioma.
Cancer research 2006 OCT
Abstract
Combined deletion of chromosomes 1p and 19q is associated with improved prognosis and responsiveness to therapy in patients with anaplastic oligodendroglioma. The deletions usually involve whole chromosome arms,suggesting a t(1;19)(q10;p10). Using stem cell medium,we cultured a few tumors. Paraffin-embedded tissue was obtained from 21 Mayo Clinic patients and 98 patients enrolled in 2 North Central Cancer Treatment Group (NCCTG) low-grade glioma trials. Interphase fusion of CEP1 and 19p12 probes detected the t(1;19). 1p/19q deletions were evaluated by fluorescence in situ hybridization. Upon culture,one oligodendroglioma contained an unbalanced 45,XX,t(1;19)(q10;p10). CEP1/19p12 fusion was observed in all metaphases and 74% of interphase nuclei. Among Mayo Clinic oligodendrogliomas,the prevalence of fusion was 81%. Among NCCTG patients,CEP1/19p12 fusion prevalence was 55%,47%,and 0% among the oligodendrogliomas,mixed oligoastrocytomas,and astrocytomas,respectively. Ninety-one percent of NCCTG gliomas with 1p/19q deletion and 12% without 1p/19q deletion had CEP1/19p12 fusion (P textless 0.001,chi(2) test). The median overall survival (OS) for all patients was 8.1 years without fusion and 11.9 years with fusion (P = 0.003). The median OS for patients with low-grade oligodendroglioma was 9.1 years without fusion and 13.0 years with fusion (P = 0.01). Similar significant median OS differences were observed for patients with combined 1p/19q deletions. The absence of alterations was associated with a significantly shorter OS for patients who received higher doses of radiotherapy. Our results strongly suggest that a t(1;19)(q10;p10) mediates the combined 1p/19q deletion in human gliomas. Like combined 1p/19q deletion,the 1;19 translocation is associated with superior OS and progression-free survival in low-grade glioma patients.
Bone morphogenetic proteins inhibit the tumorigenic potential of human brain tumour-initiating cells.
Nature 2006 DEC
Abstract
Transformed,oncogenic precursors,possessing both defining neural-stem-cell properties and the ability to initiate intracerebral tumours,have been identified in human brain cancers. Here we report that bone morphogenetic proteins (BMPs),amongst which BMP4 elicits the strongest effect,trigger a significant reduction in the stem-like,tumour-initiating precursors of human glioblastomas (GBMs). Transient in vitro exposure to BMP4 abolishes the capacity of transplanted GBM cells to establish intracerebral GBMs. Most importantly,in vivo delivery of BMP4 effectively blocks the tumour growth and associated mortality that occur in 100% of mice after intracerebral grafting of human GBM cells. We demonstrate that BMPs activate their cognate receptors (BMPRs) and trigger the Smad signalling cascade in cells isolated from human glioblastomas (GBMs). This is followed by a reduction in proliferation,and increased expression of markers of neural differentiation,with no effect on cell viability. The concomitant reduction in clonogenic ability,in the size of the CD133+ population and in the growth kinetics of GBM cells indicates that BMP4 reduces the tumour-initiating cell pool of GBMs. These findings show that the BMP-BMPR signalling system--which controls the activity of normal brain stem cells--may also act as a key inhibitory regulator of tumour-initiating,stem-like cells from GBMs and the results also identify BMP4 as a novel,non-cytotoxic therapeutic effector,which may be used to prevent growth and recurrence of GBMs in humans.
Sulforaphane targets pancreatic tumour-initiating cells by NF-kappaB-induced antiapoptotic signalling.
Gut 2009 JUL
Abstract
BACKGROUND AND AIMS: Emerging evidence suggests that highly treatment-resistant tumour-initiating cells (TICs) play a central role in the pathogenesis of pancreatic cancer. Tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) is considered to be a novel anticancer agent; however,recent studies have shown that many pancreatic cancer cells are resistant to apoptosis induction by TRAIL due to TRAIL-activated nuclear factor-kappaB (NF-kappaB) signalling. Several chemopreventive agents are able to inhibit NF-kappaB,and favourable results have been obtained--for example,for the broccoli compound sulforaphane-in preventing metastasis in clinical studies. The aim of the study was to identify TICs in pancreatic carcinoma for analysis of resistance mechanisms and for definition of sensitising agents. METHODS: TICs were defined by expression patterns of a CD44(+)/CD24(-),CD44(+)/CD24(+) or CD44(+)/CD133(+) phenotype and correlation to growth in immunodeficient mice,differentiation grade,clonogenic growth,sphere formation,aldehyde dehydrogenase (ALDH) activity and therapy resistance. RESULTS: Mechanistically,specific binding of transcriptionally active cRel-containing NF-kappaB complexes in TICs was observed. Sulforaphane prevented NF-kappaB binding,downregulated apoptosis inhibitors and induced apoptosis,together with prevention of clonogenicity. Gemcitabine,the chemopreventive agents resveratrol and wogonin,and the death ligand TRAIL were less effective. In a xenograft model,sulforaphane strongly blocked tumour growth and angiogenesis,while combination with TRAIL had an additive effect without obvious cytotoxicity in normal cells. Freshly isolated patient tumour cells expressing markers for TICs could be sensitised by sulforaphane for TRAIL-induced cytotoxicity. CONCLUSION: The data provide new insights into resistance mechanisms of TICs and suggest the combination of sulforaphane with TRAIL as a promising strategy for targeting of pancreatic TICs.
