ABSTRACT
Purpose: Cervical carcinoma is the second most common cancer among women worldwide. Viral infections, especially human papillomavirus (HPV) infections, are important factors in its etiology. Changes in apoptotic regulation are considered to have an important role in the carcinogenesis development. In this study, the relationship between apoptosis and HPV infection was investigated. Methods: HPV DNA and HPV DNA type 16 positivity were detected in 110 cervical smear samples with Real Time PCR and sequencing was performed for HPV DNA type 18. The presence of apoptosis was investigated using TUNEL and Annexin V staining methods and analyzed by fluorescence microscope and flow cytometry. Results: HPV DNA type 16 was detected in 9 samples (8.1%), HPV DNA type 18 positive in 6 samples (5.4%) and HPV types other than HPV type 16 and HPV type 18 in 9 samples (8.1%). A decrease apoptosis was found in HPV DNA positive samples compared with controls (P<0.05). Conclusion: The decrease of apoptosis during HPV infection might cause cellular immortality and then malignant transformation.

    Human apurinic/apyrimidinic (AP) endonuclease 1 (APE1) is a multifunctional enzyme involved in base excision repair (BER). APE1 cleaves DNA 5′ of an AP site to produce a single-strand break with 5′-OH and 3′-deoxyribose phosphate. In addition to its AP-endonucleolytic function,...

    Several experiments have been performed to study regularities in the induction of apoptotic cells in human lymphocytes by 60Co γ-rays at different times after irradiation. Apoptosis induction by 60Co γ-rays in human lymphocytes in different cell cycle phases (G0, S, G1, and G2) has been...

    Background: Currently, there is clear evidence that apoptosis plays an important role in the development and progression of tumors. One of the best characterized apoptosis triggering systems is the CD95/Fas/APO-1 pathway; previous reports have demonstrated high levels of soluble CD95 (sCD95) in...

    Normal human cells have a finite proliferative potential in vitro. However, some DNA viral proteins, such as SV40 Tg, can alter this and extend the lifespan after which the cells enter crisis, a period when massive cell death occurs. Based on these observations, a two-stage model for cellular...

    Neuronal cell death in the brain of macular mutant mouse, a model of copper metabolism abnormality, has features of both apoptosis and necrosis. Apoptotic cells were morphologically identified by the terminal deoxynucleotidyl transferase nick end-labeling (TUNEL) method and electron microscopy....

    Maternal effect genes encode proteins that are produced during oogenesis and play an essential role during early embryogenesis. Genetic ablation of such genes in oocytes can result in female subfertility or infertility. Here we report a newly identified maternal effect gene, Nlrp2, which plays a...

    Akabane, Aino and Chuzan virus are arthropod-borne (arbo) viruses mainly associated with reproductive failures in cattle. We investigated apoptosis in Vero cells (C-1586) infected with Akabane, Aino and Chuzan virus. The fragmentation of chromosomal DNA was simultaneously detected with the...
