Human parainfluenza type 2 virus (hPIV-2)-infected HeLa (HeLa-CA) cells and hPIV-2 V-expressing HeLa (HeLa-V) cells show high resistance to alpha/beta interferons (IFN-alpha/beta) irrespective of whether vesicular stomatitis virus or Sindbis virus is used as a challenge virus. When Sindbis virus is used, these cells show high susceptibility to human IFN-gamma. Furthermore, the multiplication of...

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...

Abstract Breast and cervical cancers are the leading cause of death in women, chemotherapy with cytotoxins is usual treatment. This study evaluated cytotoxicity guava leaf ( Psidium guajava L.) extracts as an alternative chemotherapeutic drug. Although many studies related to cytotoxic effects on cancer cells have been reported, fractions human breast (T47D, MCF-7, HeLa) never evaluated. Herein...

cervical cancer is the most common gynecologic cancer and the second most common cancer in women worldwide. herbal preparations are used to treat cancer for centuries. the aim of this study was investigate the cytotoxic effects of the methanol extract of citrullus colocynthis and volatile oils of iranian c. medica on hela cell line. after preparation extract and volatile oils, different concent...

objective(s) nonviral vector can be an attractive alternative to gene delivery in experimental study. in spite of some advantages in comparison with the viral vectors, there are still some limitations for efficiency of gene delivery in nonviral vectors. to determine the effective expression, the recombinant escherichia coli lacz genes were cloned into the different variants of pcdna3.1 and then...

We describe the use of small interfering RNAs (siRNAs) to downregulate Hand L-ferritin levels in HeLa cells. They repressed Hand L-ferritin expression to about 20-25% of the background level, both in stable and transient transfections. HeLa cells transfected with Hand L

Abstract A large common species, Syzygium aqueum , belonging to the genus possesses numerous bioactive phytochemical constituents. Moreover, different parts of this species have been used as folk medicine since centuries ago. In study, a exploration was carried out on plant’s stem bark. Isolation compounds through extraction step with some organic solvents, followed by separation and purificati...

Low power femtosecond-pulsed NIR irradiation kills HeLa cells incubated with Ag nanoplates by both photothermal effect and optical breakdown leading to plasma formation that spreads fast through the cell.

sophora pachycarpa schrenk ex c.a.mey. belongs to the family fabaceae. some species of the genus sophora have shown to possess anti-proliferative and apoptosis-inducing activites in cancer cells. however, there is no available information addressing this effect in s. pachycarpa. here, we investigated the cytotoxic effects of methanol extract and different fractions obtained from s. pachycarpa r...

salvia chorassanica bunge is one of the iranian endemic species of salvia. there is not any reported literature on s. chorassanica. this study was designed to examine the in-vitro anti-proliferative and proapoptotic effects of the methanol extract of s. chorassanica and its fractions on hela cell line. cells were cultured in ex-cell®, an animal free medium specially designed for hela cell line ...
