The poliovirus (PV)-induced cytopathic effect (CPE) was blocked in neural cells but not in HeLa cells by the addition of monoclonal antibody (MAb) against PV or the human PV receptor (CD155) 2 h postinfection (hpi). Since each MAb has the ability to block viral infection, no CPE in PV-infected neural cells appeared to result from the blockade of multiple(More)
IGF2, a maternally imprinted foetal growth factor gene, is implicated in many childhood tumours including hepatoblastoma (HB); however, the genetic and epigenetic alterations have not comprehensively been studied. We analysed the methylation status of the H19 differentially methylated region (DMR), loss of heterozygosity (LOH) and allelic expression of IGF2(More)
BACKGROUND Bilateral Wilms tumours (BWTs) occur by germline mutation of various predisposing genes; one of which is WT1 whose abnormality was reported in 17-38% of BWTs in Caucasians, whereas no such studies have been conducted in East-Asians. Carriers with WT1 mutations are increasing because of improved survival. METHODS Statuses of WT1 and IGF2 were(More)
BACKGROUND A nucleotide change from U to C at position 472 in the 5' non-coding region of the type 3 poliovirus is associated with increased neurovirulence. Moreover, the proportion of type 3 polioviruses containing this mutation (472-C revertants) correlates with the neurovirulence of a particular sample. We used mutant analysis by PCR and(More)
Telomerase, an enzyme related with cellular immortality, has been extensively studied in many kinds of malignant tumours for clinical diagnostic or prognostic utilities. Telomerase activity is mainly regulated by the expression of hTERT (human telomerase reverse transcriptase), which is a catalytic component of human telomerase. To evaluate whether the(More)
