Summary
Human papillomavirus (HPV) infection activates telomerase in genital condyloma acuminatum (CA). Higher telomerase activity was observed with HPV types 16/18, suggesting a role in CA development and carcinogenesis.
Area of Science:
- Oncology
- Virology
- Molecular Biology
Background:
- Condyloma acuminatum (CA) is a genital infection caused by human papillomavirus (HPV).
- The role of telomerase in the pathogenesis of genital CA requires further investigation.
- HPV infection is linked to cellular proliferation and potential carcinogenesis.
Purpose of the Study:
- To investigate the function of telomerase in the occurrence, development, and carcinogenesis of genital CA.
- To determine telomerase activity in relation to HPV presence and types in CA tissues.
Main Methods:
- Modified telomerase repeat amplification protocol (TRAP) assay was used to determine telomerase activity.
- Polymerase chain reaction (PCR) with typing-specific primers was employed for HPV typing.
- Analysis included 42 genital CA biopsies and 30 control tissue samples.
Main Results:
- All genital CA samples were positive for HPV, with HPV types 6/11 in 32 cases, 16/18 in 3, and mixed types in 7.
- Telomerase activity was detected in all CA patients, but not in normal skin samples (16.7% telomerase expression).
- Telomerase activity was significantly higher in CA samples with HPV types 16/18 compared to those with HPV types 6/11.
Conclusions:
- HPV infection is associated with hyperplasia in genital CA.
- Telomerase activation by HPV, particularly HPV types 16/18, may play a significant role in the etiology and carcinogenesis of genital CA.

02:41Telomeres and Telomerase
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded DNA.

Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
