Molecular epidemiology studies have shown that some types of HPV are causally linked with precancerous lesions of cervix and invasive cervical cancer. In our study, we enrolled HPV infected women with repeated Pap smears (Pap II) in Slovenia and verified HPV infection. HPV genotypes were determined using the method of enzyme restriction of PCR products amplified with group-specific oligonucleotide primers PGMY11/PGMY09 (PCR-RFLP) and restricted with seven different restriction endonucleases. In women aged < or = 30 years we detected 21 different types of HPV and a very high percentage (76.5%) of multiple infections. In women aged > 30 years we detected 11 different types of HPV and found the predominance of a single HPV type infection (85%). In women aged < or = 30 years the most frequent infections, and also equally distributed (10.50%), were those with high-risk types HPV16 and HPV73 and with a probably high-risk type HPV26. In women aged > 30 years most frequent infections, and also equally distributed (18.20%), were those with high-risk type HPV16 and probably high-risk type HPV53. The HPV genotypes were classified by the newest classification according to their oncogenic potential and we have referred the presence of newly high-risk and probably high-risk types of HPV at observed population of women in Slovenia. Using group-specific primers PGMY11/PGMY09 and seven restriction endonucleases in PCR-RFLP method for genotypization of HPV we identified single types of HPV included in large percentage of multiple infections of young women with repeated Pap II smears.

In recent years, epigenetic modifications have attracted significant attention due to their unique regulatory mechanisms and profound biological implications. Acting as a bridge between environmental stimuli and changes in gene activity, they reshape gene expression patterns, providing organisms with regulatory mechanisms to respond to environmental changes. A growing body of evidence indicates that epigenetic regulation plays a crucial role in the pathogenesis and progression of psoriasis.

This study examined the relationship between the vaginal microbiome, HPV infection, and cervical intraepithelial neoplasia (CIN) in 173 women. Subjects were grouped by HPV status and cervical lesion severity, ranging from HPV-negative to CIN Grade 2 or higher. Using VALENCIA classification, the study identified different community state types (CSTs) of vaginal microbiota, with CST IV subtypes (Staphylococcus dominated) showing high diversity and increased pathogenic bacteria.

Incorporating molecular testing for human papillomavirus (HPV) into the screening of cervical specimens can improve risk stratification and, in turn, patient management. Infection with a high-risk (HR) HPV genotype is associated with greater risk for persistent infection, viral integration, and progression of cervical neoplasia. Current guidelines consider HPV 16 or HPV 18 clinically actionable with referral to colposcopy; however, 12 Other HR HPV genotypes have been associated with cervical cancer risk, suggesting a benefit of extended genotyping.

Hormonal contraceptives may influence HPV acquisition, persistence, and clearance, but evidence remains inconclusive. This sub-study aimed to evaluate the impact of different hormonal contraceptives on HPV prevalence and genotype distribution in AGYW.

Productive infections of oncogenic human papillomaviruses (HPVs) are closely linked to the differentiation of host epithelial cells, a process that the virus manipulates to create conditions favorable to produce virion progeny. This viral interference involves altering the expression of numerous host genes. Among these, proprotein convertases (PCs) have emerged as potential oncogenes due to their central role in cellular functions.
