Article Abstract
Objectives: HPV infection and HPV DNA integration can lead to cervical cancer, but the relationship with lesion severity is unclear. This study aimed to investigate the correlation between HPV integration profile and cervical lesion extent.
Materials And Methods: Twenty patients representing cervicitis, CIN I, CIN II, and CIN III underwent nanopore sequencing for HPV genotype and integration site analysis. HPV integration profiles were correlated with lesion severity. Gene Ontology (GO) and KEGG analysis were used to identify stage-specific genes and pathways.
Results: HPV integration rates were 60, 60, 100, and 100% for cervicitis, CIN I, CIN II, and CIN III, respectively, with varying numbers of integrated genes. Each group had specific stage-related genes, with 83 shared genes linked to neuron development and cell-cell processes. CIN II and CIN III displayed more cancer-related pathway enrichment than earlier stages.
Conclusion: A positive correlation exists between HPV integration frequency and cervical lesion stage. Late-stage lesions showed heightened enrichment in cancer-related pathways through specific HPV-integrated genes.

Introduction: Despite high coverage of routine childhood vaccines, uptake of the human papillomavirus (HPV) vaccine in the Pacific Island nation of Tonga has been slow. Culturally appropriate communication resources on the importance, safety, and effectiveness of the HPV vaccine are critical to support acceptance and uptake. To develop these resources, it is important to understand what people want to know.

Screening for high-risk human papillomavirus (hrHPV) infection is essential for cervical cancer prevention. However, developing a simple, portable, and low-cost hrHPV genotyping method remains challenging, particularly in resource-limited settings. Herein, we present an innovative amplification-free, point-of-care hrHPV genotyping platform integrating CRISPR/Cas12a with alkaline phosphatase (ALP)-mediated surface plasmon effect.

Background: Bone metastasis (BM) in breast cancer affects patient prognosis, but its molecular mechanisms and relationship with the gut microbiome are not well understood. This study aims to explore gene expression and gut microbiome differences between BM and non-bone metastasis (BNM) patients, which could shed light on cancer progression and metastasis.
Methods: We utilized a multi-omics approach, integrating transcriptomic and microbiomic data.

Department of Epidemiology and Biostatistics, West China School of Public Health and West China Fourth Hospital, Sichuan University, Chengdu, China.
Background: The HPV infection rate in Sichuan exceeds the national average. The provincial government has initiated vaccination programs, with a particular focus on impoverished areas such as the Ganzi, Aba, and Liangshan prefectures, where both the HPV disease burden is elevated and vaccination uptake remains suboptimal. This study aimed to investigate HPV vaccination among adolescent girls in these prefectures, evaluate caregivers' knowledge and attitudes, identify factors influencing their willingness to vaccinate their daughters, and examine existing policies to provide evidence-based recommendations for improving vaccination strategies.

Cervical cancer remains a major health burden, particularly in low- and middle-income countries, despite being one of the most preventable cancers. WHO's 90-70-90 targets aim to eliminate cervical cancer globally by 2030. These targets include 90% of girls fully vaccinated with the HPV vaccine by the age of 15 years, 70% of women screened using a high-performance test by the age of 35 years and again by 45 years, and 90% of women with cervical disease receiving appropriate treatment.
