High aldehyde dehydrogenase (ALDH) activity characterizes a subpopulation of cells with cancer stem cell (CSC) properties in several malignancies. To clarify whether ALDH can be used as a marker of cervical cancer stem cells (CCSCs), ALDH high and ALDH low cells were sorted from 4 cervical cancer cell lines and 5 primary tumor xenografts and examined for CSC characteristics. Here, we demonstrat...

Cervical cancer is the third most common cancer in women. Radiotherapy resistance remains a major obstacle for patients with cervical cancer. Somatic alterations in human genomes are responsible for radiotherapy resistance. Here, we performed single cell whole genome sequencing on 13 cells before radiotherapy and 12 cells after radiotherapy from a Chinese woman patient with cervical carcinoma. ...

Cervical cancer is a major cause of cancer death in females worldwide. Cervical cancer stem-like cells (CSCs)/cancer-initiating cells (CICs) are resistant to conventional radiotherapy and chemotherapy, and CSCs/CICs are thought to be responsible for recurrence. Eradication of CSCs/CICs is thus essential to cure cervical cancer. In this study, we isolated cervical CSCs/CICs by sphere culture, an...

Human papillomavirus (HPV)-encoded proteins may provide targets for CD8+ or CD4+ T lymphocytes infiltrating into cervical cancer. We established an MHC class II-restricted CD4+ T cell line from a patient with cervical cancer that recognizes autologous (HPV35+, HPV59+) cervical cancer cells and the HLA-DR4-matched cervical cancer cell line Me180 (HPV68+) as determined by TNF-alpha secretion. Exp...

objective(s):cervical cancer is a malignancy that is the second most common cause of death from cancer in women throughout the world. paederus beetle (paederus fuscipes) extract (pbe), contains bioactive compounds such as pederine which has cytotoxic properties and blocks dna and protein synthesis at very low concentrations. in this investigation we tried to determine the effects co-treatment w...

Nestin expression reportedly correlates with aggressive growth, metastasis, poor prognosis and presence of cancer stem cells (CSCs) in various tumors. In this study, we determined the expression and role of nestin in cervical intraepithelial neoplasia (CIN) and cervical cancer. We performed immunohistochemical and in situ hybridization analyses of...

BACKGROUND Cervical cancer is the second most common cancer in females. Recent reports have revealed the critical role of cervical cancer stem cells (CSCs) in tumorigenicity and metastasis. Previously we demonstrated that A1E exerts an anti-proliferative action, which inhibits the growth of cervical cancer cells. METHODS A1E is composed of 11 oriental medicinal herbs. Cervical cancer cell cul...

Ataxin-1 (ATXN1) is a coregulator protein within which expansion of the polyglutamine tract causes spinocerebellar ataxia type 1, an autosomal dominant neurodegenerative disorder. Previously, we reported that ATXN1 regulates the epithelial-mesenchymal transition of cervical cancer cells. In the present study, we demonstrate that ATXN1 is involved in cervical cancer tumorigenesis by promoting th...

Repeated infection with high-risk HPV is a major cause for the development and metastasis of human cervical cancer, even though the mechanism of the metastasis is still not completely understood. Here, we reported that miR-218 (microRNA-218) was downregulated in cervical cancer tissues, especially in metastatic cancer tissues. We found that miR-218 expression was associated with clinicopatholog...

CD147, a multifunction glycoprotein of the immuno-globulin family, is associated with many types of tumors, and the overexpression of CD147 can enhance malignancy. However, the role of CD147 in cervical cancer remains unclear. In the present study, cervical cancer cells were found to express much more CD147 protein and isoform‑4 than normal cervical cells (P<0.05), suggesting that CD147 and iso...
