Abstract It is not known whether the lack of antibody response against human papillomavirus (HPV) type 16 E6 and E7 among some cervical cancer patients is due to naturally existing sequence variations. In this study, naturally occurring HPV-16 E6 and E7 variants (including the prototype) were cloned, antigens were expressed by in vitro transcription and translation, and the humoral immune response of 34 HPV-16-positive cervical cancer patients was analyzed by radioimmunoprecipitation assay (RIPA). In addition, the RIPA results were compared with those of a sandwich-protein ELISA, to further substantiate antibody status. Sera lacking E6 reactivity by RIPA remained negative by protein ELISA. All E6 antigens (the prototype and the variants 350G inverted question markL83V, 131G inverted question markR10G/350G inverted question markL83V, 335T inverted question markH78Y/350G inverted question markL83V, 345G inverted question markY81C/350G inverted question markL83V, and African 2 inverted question markAf2) showed cross-reactivity by RIPA. The lack of HPV-16 E6 or E7 antibodies is independent of naturally occurring variants in cervical cancer patients. Thus, testing for HPV-16 E6 or E7 prototype antigens seems to be sufficient in serological assays.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
