Human papillomavirus type 16 (HPV-16) is associated with abnormal Papanicolou smears, indicative of cervical intraepithelial neoplasia. HPV-16 is the most common genital HPV and is found in up to 40% of young women with normal cervical cytology. In order to investigate whether transcriptionally active HPV-16 infection is associated with abnormal cervical smears, a reverse transcription-nested PCR assay with primers from the E5 open reading frame was developed to detect all HPV-16 early-region mRNA (E-mRNA) transcripts. It was used to study HPV-16-infected women with normal and abnormal cervical cytologies to obtain evidence of active infection. Among HPV-16 DNA-positive women, HPV-16 E-mRNA was detected in 15 of 37 (40.5%) women with abnormal cervical cytology but in only 4 of 35 (11.4%) women with normal cytology (P = 0.007). Thus, HPV-16 E-mRNA transcription is associated with abnormal cervical smears and may have value as a prognostic marker of progressive disease.
16型人乳头瘤病毒(HPV-16)与巴氏涂片异常有关,提示宫颈上皮内瘤变。HPV-16是最常见的生殖道HPV,在宫颈细胞学正常的年轻女性中,高达40%可检测到该病毒。为了研究转录活跃的HPV-16感染是否与宫颈涂片异常有关,开发了一种使用E5开放阅读框引物的逆转录巢式PCR检测方法,以检测所有HPV-16早期区域mRNA(E-mRNA)转录本。该方法用于研究HPV-16感染且宫颈细胞学正常和异常的女性,以获取活跃感染的证据。在HPV-16 DNA阳性女性中,宫颈细胞学异常的37名女性中有15名(40.5%)检测到HPV-16 E-mRNA,而宫颈细胞学正常的35名女性中只有4名(11.4%)检测到(P = 0.007)。因此,HPV-16 E-mRNA转录与宫颈涂片异常有关,可能作为疾病进展的预后标志物具有价值。
