Background: Aloe-emodin is an anthraquinone with potential pharmacological properties, including numerous antitumor properties. The purpose of the study was to determine whether aloe-emodin induces mitotic death in cervical cancer cells.
Materials And Methods: Analysis of morphological changes as surrogate mitotic death indicators in HeLa cells was carried out using optical, fluorescence and electron microscopy. Viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide reduction assay. Cell-cycle analysis was performed using flow cytometry.
Results: Aloe-emodin increased the number of multinucleate cells, giant and micronuclear cells. There was a concentration-dependent decrease in the mitotic index with a predominance of cells in the metaphase of the mitotic process and inhibition of division in the G/M phase of the cell cycle. The presence of cells with abnormal mitosis and cells with injury to the division spindle was also demonstrated.
Conclusion: Aloe-emodin induces mitotic catastrophe in cervical cancer cells.

Objective: The purpose of this review was to examine new evidence since our 2019 guidelines for cervical cancer (CC) screening in non-HIV immunocompromised persons and to provide updated recommendations based on literature review and expert opinion. In addition, human papillomavirus (HPV) vaccine efficacy in these populations was reviewed.

Background: Fumarate hydratase-deficient renal cell carcinoma (FHRCC) is an aggressive carcinoma that typically presents as advanced-stage disease. Prompt recognition of FHRCC is critical for appropriate clinical care and genetic counseling for patients and family members. However, diagnosing FHRCC from cytology specimens is challenging, with limited characterization and no reports describing prospectively identified cases.

Tumor-associated macrophages (TAMs) are important immune cells in the tumor micro-environment (TME) and play a key role in the occurrence and development of cervical cancer. Besides, targeting TAMs can significantly inhibit cervical cancer tumor growth, invasion, metastasis, and angiogenesis as well as affect immune regulation. This review summarizes the correlation between TAM and tumors, the mechanism of action of TAM in cervical cancer, and the potential application of TAM in the treatment of cervical cancer.

Background Cervical cancer typically progresses over 10-20 years, making it a preventable disease and underscoring the importance of screening. In low-resource settings, Papanicolaou (Pap) smears and visual inspection with acetic acid (VIA) serve as primary screening tools. This study was conducted as part of the noncommunicable disease camps organized by the government of Karnataka, India.
