Cervical cancer is a malignant tumor of the female reproductive system. At present, its occurrence, development and transfer mechanism are not entirely clear. APMAP (Adipocyte Plasma Membrane Associated Protein) is a glycosyl type II transmembrane protein that is mainly distributed in the plasma membrane and endoplasmic reticulum of adipocytes. APMAP has been reported to be involved in lipid transport and can induce epithelial-mesenchymal transition of prostate cancer and the liver metastasis of colorectal cancer. However, the role of APMAP in cervical cancer is still unknown. We analyzed the expression and prognosis of APMAP using data in both the GEO and the TCGA databases. We analyzed the function of APMAP using Transwell, wound healing assay and flow cytometry, and assessed the main mechanisms of APMAP by RT-PCR and Western blotting. We found that APMAP was highly expressed in cervical cancer tissues, and patients with high expression had poor prognosis. The functional experiments demonstrated that APMAP knockdown significantly inhibited the migration ability of cervical cancer cells, but had little effect on cell apoptosis. Mechanically, APMAP promotes cervical cancer cell migration and epithelial-mesenchymal transition by activating the Wnt/β-catenin pathway. Overall, APMAP is a potential prognostic marker as well as a therapeutic target of cervical cancer.

Background: As a prevalent and deadly malignant tumor, the treatment outcomes for late-stage patients with cervical squamous cell carcinoma (CSCC) are often suboptimal. Previous studies have shown that tumor progression is closely related with tumor metabolism and microenvironment reshaping, with disruptions in energy metabolism playing a critical role in this process. To delve deeper into the understanding of CSCC development, our research focused on analyzing the tumor microenvironment and metabolic characteristics across different regions of tumor tissue.

CRISPR-Cas-based technology, emerging as a leading platform for molecular assays, has been extensively researched and applied in bioanalysis. However, achieving simultaneous and highly sensitive detection of multiple nucleic acid targets remains a significant challenge for most current CRISPR-Cas systems. Herein, a CRISPR Cas12a based calibratable single particle counting-mediated biosensor was constructed for dual RNAs logic and ultra-sensitive detection in one tube based on DNA Tetrahedron (DTN)-interface supported fluorescent particle probes coupled with a novel synergistic cascaded strategy between CRISPR Cas13a system and strand displacement amplification (SDA).

Objective: To explore the risk factors associated with the pathological progression to invasive carcinoma following the conization of cervical high-grade squamous intraepithelial lesions (HSIL) and to construct a risk prediction model to guide preoperative risk assessment and optimize the selection of surgical approaches.
Methods: A retrospective analysis was conducted on the clinical data of 3337 patients who underwent cervical conization for HSIL at Hunan Provincial Maternal and Child Health Care Hospital from December 2016 to March 2022. The patients were categorized into the pathological progression group (398 cases) and the nonprogression group (2939 cases) based on postconization pathology results.

Department of Pharmacy, Huaihe Hospital, Henan University, Henan, China.
Background: The prophylactic vaccines available to protect against infections by human papillomavirus (HPV) are well tolerated and highly immunogenic. This systematic review and meta-analysis aimed to explore the efficacy of HPV vaccination on the risk of HPV infection and recurrent diseases related to HPV infection in individuals undergoing local surgical treatment.
Methods: A literature search was performed using PubMed/MEDLINE, Embase, the Cochrane Library, Scopus, Web of Science, and bioRxiv/medRxiv from inception to July 15, 2024.
