Objective: Cervical cancer is the second most common cause of death from cancer in women throughout the world. The aim of this study was to evaluate the cytotoxic activity of Kelussia odoratissima (K. odoratissima) extract associated with radiotherapy in cervical cancer cells (HeLa cell line).Materials and Methods: Different concentration of the extract (25-500µg/ml) was tested in HeLa cell lin...

Conducting cell apoptosis pathways is a novel strategy in cancer treatment. This study aimed to explain that C. botrys essential oil could induce apoptosis and arrest the cell cycle in HeLa cells. Cytotoxic and apoptogenic effects of the essential oil of Jerusalem-oak (Chenopodium botrys L.), which was obtained from the aerial parts of the plant, were evaluated in HeLa cells. Cell viability was...

background: flavonoids have a variety of biological activities, such as anti-allergic, anti-inflammatory, anti-oxidative, free radical scavenging, and anti-mutagenic. methods: the cytotoxic effects of three synthesized flavonoid derivatives (k3, k4 and k5) were evaluated against hela , mda-mb -231 and ht-29 cancer cells using mtt assay. results: the results showed that these flavonoids were not...

We measured mitosis-promoting factor (MPF) activity in two cell lines, CHO and HeLa, extensively used at mitosis as inducers in the assay of premature chromosome condensation to study the yield and the repair kinetics of radiation damage in interphase chromosomes of diverse cell lines. We found a 2.5-fold higher MPF activity in HeLa as compared to CHO mitotic cells per mg of crude extract prote...

In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,...

Sulfonamides are the first effective chemotherapeutic agents used for several years to cure or prevent systemic bacterial infections. In addition, this agents showed anti-carbonic anhydrase and cause cell cycle perturbation in the G1 phase, disruption of microtubule assembly, suppression of the transcription activator Nf-Y, angiogenesis and matrix metalloproteinase (MMP). In recent years, novel...

Objective: Cervical cancer is the second most common type of cancer among women, worldwide; and for treatment of this type of cancer radiotherapy is commonly used. Ferula gummosa Boiss(“Barije” in Persian, from the family Apiaceae), (F. gummosa), is an extremely precious medicinal plant which naturally grows throughout the Mediterranean and Central Asia and is a native plant in Iran. The presen...

Background and Aim: Cervical and breast cancer are considered to be the most common cause of death among Iranian women. Various studies have shown that probiotics are effective fighting cancer. The aim of the present study was to investigate the effect of Lactobacillus brevis on apoptosis and casp (casp3, casp8) gene expression in HeLa cancer cells.  Materials and Methods: In this study, L. br...

Campylobacter upsaliensis is an emerging human enteropathogen. However, little is known about the pathogenesis of C. upsaliensis infection. In this study the authors demonstrate that C. upsaliensis whole-cell preparations and extracts produce a cytolethal distending toxin (CDT)-like effect on HeLa cells characterized by progressive distension and nuclear fragmentation culminating in cell death ...
