SK-v 细胞是从癌前外阴病变建立的,含有整合在单个细胞位点的人乳头瘤病毒 16 型 (HPV-16) 序列,并且源自体内存在的细胞克隆。通过 cDNA 异源双链图谱和测序以及 RNase 图谱分析 SK-v 细胞中 HPV-16 基因组的转录。病毒序列被证明被转录成病毒-细胞融合信使。两个主要转录物具有编码截短的E6蛋白、E7蛋白和E1-E4融合蛋白的能力,但它们的3'病毒-细胞连接不同。次要转录本具有编码全长 E6 蛋白和 E6 的另一个截短版本的能力。发现 SK-v 细胞和 CaSki 细胞(源自浸润性宫颈癌的细胞系)中 E6-E7 区域的转录模式相同。免疫沉淀实验表明,E6 蛋白 (18K) 和主要的 E7 蛋白 (20K) 在 SK-v 细胞中与 CaSki 细胞中一样表达。 SK-v 细胞中 E7 蛋白的含量低两到三倍,但半衰期相同(约 1 小时)。
The SK-v cells, established from a premalignant vulvar lesion, contain human papillomavirus type 16 (HPV-16) sequences integrated at a single cellular site and derive from a cell clone present in vivo. Transcription of the HPV-16 genome in SK-v cells was analysed by cDNA heteroduplex mapping and sequencing, and by RNase mapping. Viral sequences were shown to be transcribed into virus-cell fusion messengers. The two major transcripts have a coding capacity for a truncated E6 protein, an E7 protein and an E1-E4 fusion protein, but differ in their 3' virus-cell junction. Minor transcripts have a coding capacity for a full-length E6 protein and another truncated version of E6. The transcription pattern in the E6-E7 region was found to be the same both in SK-v cells and in CaSki cells, a line derived from an invasive cervical carcinoma. Immunoprecipitation experiments showed that the E6 protein (18K) and, predominantly, the E7 protein (20K) are expressed in SK-v cells as in CaSki cells. The E7 protein was found in a two- to threefold lower amount in SK-v cells, but showing the same half-life (about 1 h).
