Samenvatting Het doel van deze studie was te onderzoeken of de bevindingen op een 18 F‑DCFPyL PET/CT-scan leiden tot verandering het behandeladvies voor patiënten met biochemisch recidief (BCR) prostaatkanker. 253 BCR-prostaatkanker bij wie werd gemaakt ter herstadiëring, werden geïncludeerd. Twee urologen formuleerden voorgestelde behandeling elke patiënt voor- en nadat zij kennis hadden genom...
Background: Identifying prostate cancer (PCa) patients with a worse prognosis and higher risk of biochemical recurrence (BCR) is essential to guide treatment choices. Here, we aimed identify possible imaging biomarker (perfusion/diffusion + radiomic features) profiles extracted from MRIs that were able discriminate according their or the occurrence BCR 10 years after diagnosis, as well evaluate...
The c-Fes protein-tyrosine kinase exhibits strong expression in myeloid hematopoietic cells. Previous studies have shown that Fes induces differentiation in the chronic myelogenous leukemia-derived cell line K-562, suggesting that the Fes signal for differentiation is dominant to the Bcr-Abl signal for transformation in these cells. In addition, Fes has been shown to associate with and phosphor...
A novel variant of the chimeric BCR-ABL mRNA transcript was detected in a patient with Philadelphia chromosome-negative (Ph-) chronic myelogenous leukemia (CML) by multiplex reverse-transcription polymerase chain reaction (RT-PCR). Sequence analysis of the fusion region of the amplified cDNA fragment showed an in-frame joining of exon e6 of the BCR gene and exon a2 of the ABL gene, giving rise ...
The B lymphocyte adaptor molecule of 32 kDa (Bam32) is an adaptor that plays an indispensable role in BCR signaling. In this study, we found that upon BCR ligation, Bam32 is recruited to the plasma membrane where it associates with BCR complexes and redistributes and internalizes with BCRs. BCR ligation induced colocalization of Bam32 with lipid rafts, clathrin, and actin filaments. An inhibito...
Chronic myelogenous leukemia (CML) results from the transformation of a primitive hematopoietic cell by the BCR/ABL gene. BCR/ABL signaling has been studied in cell lines and murine models, but the transforming effects of BCR/ABL are highly dependent on cellular context, and mechanisms responsible for the transformation of primitive human hematopoietic cells remain poorly understood. Current ta...
Kinase inhibitors that target Bcr-Abl are highly effective in the treatment of chronic myeloid leukemia (CML). However, these inhibitors are often invalidated due to the drug resistance. Therefore, the discovery and development of novel Bcr-Abl inhibitors is required to overwhelm the drug resistance in the treatment of CML resistant to the currently used first-line Bcr-Abl inhibitors. Herein we...
HL-60/Bcr-Abl cells, with ectopic expression of p185 Bcr-Abl tyrosine kinase (TK), and K562 cells, with endogenous expression of p210 Bcr-Abl TK, display a high degree of resistance against antileukemic drug-induced apoptosis (G. Fang et al., Blood, 96: 2246-2256, 2000). Present studies demonstrate that treatment with ansamycin antibiotic geldanamycin (GA), or its less toxic analogue 17-allylam...
The t(9;22) in chronic myelogenous leukemia (CML) may be reciprocal or, in a minority of cases, may result in an extensive deletion of a portion of the major breakpoint cluster region (M-bcr) of the BCR. This report provides evidence of the duplication of small segments within the M-bcr in a small group of patients with CML. Southern blots of Bgl II and Bgl II/BamHI double-digested DNA from the...
The aim of this study was to enhance the antileukemic efficacy of the alkylphosphocholine erucylphospho-N,N,N-trimethylpropylammonium (ErPC3) in chronic myeloid leukemia (CML)-derived cell lines by a bcr-directed antisense oligonucleotide (ASO-bcr). The mechanism was substantiated by Western blotting of the BCR-ABL expression level of CML cells, and the efficacy was substantiated by inhibition ...
