We previously identified MIM-A (missing in metastasis, MTSS1) by differential display techniques as missing in invasive, metastatic bladder cancer cell lines and suggested that MIM-A is a novel putative metastasis suppressor gene. Characterization of the MIM gene revealed a WH2 (Wiskott-Aldrich syndrome protein homology 2) domain in the C-terminus that is(More)
Down-regulation of the KAI1 (CD82) metastasis suppressor is common in advanced human cancer, but underlying mechanism(s) regulating KAI1 expression are only now being elucidated. Recent data provide evidence that low levels of KAI1 mRNA in LNCaP cells are caused by binding of beta-catenin/Reptin complexes to a specific motif in the proximal promoter, which(More)
A molecular mechanism to explain reduced KAI1 expression in invasive and metastatic tumour cells remains elusive. In this report, we extend an earlier study in bladder cells to confirm that a 76 bp region of the KAI1 promoter (residues −922 to −847), with binding motifs for p53, AP1 and AP2, is required for high level activity of a KAI1 reporter in prostate(More)
BACKGROUND Myocardial injury after noncardiac surgery (MINS) was defined as prognostically relevant myocardial injury due to ischemia that occurs during or within 30 days after noncardiac surgery. The study's four objectives were to determine the diagnostic criteria, characteristics, predictors, and 30-day outcomes of MINS. METHODS In this international,(More)
<i>Background.</i> The measurement of gaseous compounds in exhaled breath, such as volatile organic compounds (VOCs), may provide a noninvasive technique for assessing lung pathology, some of which are associated with lung cancer (LC). VOC analysis is laborious while electronic noses are emerging as rapid detectors of an array of gaseous markers recognizing(More)
OBJECTIVE To investigate the relationship between the expression of the cancer metastasis suppressor gene KAI1 and MMP-2 and MMP-9 in human bladder cancer cell lines that express variable levels of KAI1. MATERIALS AND METHODS Five bladder cancer cell lines (BL-28/0, BL-13/0, BL-17/0/×1, B10, and D2) were grown in standard culture conditions. Gelatinase(More)
Mutations in the p53 tumour suppressor gene are generally believed to be a late event in the progression of prostate cancer, and are associated with androgen independence, metastasis, and a worse prognosis. In this review, we examine the current literature available on p53 mutations and focus on stages A (T1) and B (T2) of prostate cancer. We report here(More)
The molecular basis for downregulation of the KAI1 metastasis suppressor gene in invasive and metastatic human cancers is unknown. We have used bisulphite methylation analysis of DNA from paraffin-embedded invasive bladder tumour samples and from bladder cancer cell lines to determine if hypermethylation of a CpG island within the KAI1 promoter is(More)
This study has investigated the impact of three specific dominant-negative p53 mutants (F134L, M237L, and R273H) on tumorigenesis by LNCaP prostate cancer cells. Mutant p53 proteins were associated with an increased subcutaneous "take rate" in NOD-SCID mice, and increased production of PSA. Tumors expressing F134L and R273H grew slower than controls, and(More)
It has been proposed that a 356 amino acid protein encoded by the MIM (Missing In Metastasis) gene on Chromosome 8q24.1, is a bladder cancer metastasis suppressor. Recently, Machesky and colleagues [Biochem. J. 371 (2003) 463] identified MIM-B, a 759 amino acid protein, of which the C-terminal 356 amino acids are almost identical to MIM. Importantly, PCR(More)
