In order to evaluate the potential application value of cidofovir (CDV) in the prevention of human papillomavirus (HPV) infection and treatment of cervical cancer, the inhibitory effect of CDV on the proliferation of HPV 18-positive HeLa cells in cervical cancer was preliminarily investigated, using cisplatin (DDP) as a positive control. An MTT assay was used to analyze the effects of CDV and D...

McCoy cell monolayers were compared with HeLa cell monolayers for the detection of Clostridium difficile toxin in 301 stool samples. Tests were positive (greater than or equal to 1/100 dilution) in 83 and 81 specimens tested with McCoy and HeLa cell monolayers, respectively. McCoy cell suspensions were compared with HeLa cell monolayers in 532 stool filtrates. Overall, 90 positive specimens wer...

Kaempferia parviflora (KP) has been traditionally used as a folk remedy to treat several diseases including cancer, and several studies have reported cytotoxic activities of extracts of KP against a number of different cancer cell lines. However, many aspects of the molecular mechanism of action of KP remain unclear. In particular, the ability of KP to regulate cancer cell growth and survival s...

Radiotherapy with γ-radiation is widely used in cancer treatment to induce DNA damage reducing cell proliferation and to kill tumor cells. Although RhoA GTPase overexpression/hyperactivation is observed in many malignancies, the effect of RhoA activity modulation on cancer radiosensitivity has not been previously investigated. Here, we generated stable HeLa cell clones expressing either the dom...

Objective: Lactobacillus has been shown to inhibit proliferation of various cancer cells, but the effects vaginal on cervical cells have rarely reported. The goal this investigation was assess anti-proliferative effect cell line HeLa (Human Cervical Carcinoma Cell) and potential probiotic properties plantarum L4 isolated from cervicovaginal flora healthy women in Turkey. Materials Methods: Mole...

BACKGROUND & OBJECTIVES Studies of interaction between viruses and mitochondria have shown that viruses can affect the mitochondria. Also linkage between human diseases and mitochondrial dysfunction has been revealed. We studied the effect of measles virus (MV) on cell respiration in MV infected Hela cells to see any possible changes in mitochondrial respiration. METHODS Total cell respiratio...

Objective: To evaluate the inhibition function of Photodynamic Therapy mediated by Tetrakismethylpiridiniumylporphine (TMPyP4-PDT) in cervical cancer cell lines (Hela and Caski) in vitro and its effects on the expression levels of c-myc and hTERC, analyzing the advantages of TMPyP4-PDT for the treatment of cervical cancer. Methods: The cervical cancer cell lines (Hela and Caski) in vitro irradi...

PX-12, as an inhibitor of thioredoxin (Trx), has antitumor activity. However, little is known about the toxicological effect of PX-12 on cervical cancer cells. In the present study, the growth inhibitory effects of PX-12 on HeLa cervical cancer cells in association with reactive oxygen species (ROS) and glutathione (GSH) levels were investigated. Based on MTT assays, PX-12 inhibited the growth ...

BACKGROUND Cervical cancer is the second most common female cancer worldwide. Inhibitors of apoptosis proteins (IAPs) block apoptosis; therefore, therapeutic strategies targeting IAPs have attracted the interest of researchers in recent years. Apollon, a member of IAPs, inhibits apoptosis and cell death. RNA interference is a pathway in which small interfering RNA (siRNA) or shRNA (short hairpi...
