Many Gram-negative bacteria use N-acyl-l-homoserine lactones (AHLs) as quorum-sensing signal molecules. We have reported that Acinetobacter strains isolated from activated sludge have AHL-degrading activity. In this study, we cloned the amiE gene as an AHL-degradative gene from the genomic library of Acinetobacter sp. strain Ooi24. High-performance liquid(More)
We analyzed telomerase activities and gene expressions of telomerase components: hTERT, hTR, hTEP1, telomeric repeat binding factors: TRF1, TRF2, and c-myc, Max and Mad in human normal oral and ectocervical epithelial keratinocytes, comparing with those of squamous carcinoma cells and HPV16- or SV40-immortalized cells. Significant telomerase activity and(More)
