It has been reported that several conifers possess cytotoxic activities on some human tumor cell lines. Taxol as a natural cytotoxic compound has been extracted from this family. In a program to screen the cytotoxic effects of natural resources, male and female branchlets, fruit or bark of two different species of Iranian conifers were collected, identified and the cytotoxic effects of their hy...

MicroRNAs (miRNAs) have significant roles in cell processes, including proliferation, apoptosis and stress responses. To investigate the involvement of miR-99 in the inhibition of HeLa cell proliferation, an miR-99 gene expression vector (pU6.1/miR-99), which overexpressed miR-99 in HeLa cells after transient transfection, was constructed. The expression of miR-99 was detected by qPCR. Cell pro...

HeLa is the most widely used model cell line for studying human cellular and molecular biology. To date, no genomic reference for this cell line has been released, and experiments have relied on the human reference genome. Effective design and interpretation of molecular genetic studies performed using HeLa cells require accurate genomic information. Here we present a detailed genomic and trans...

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...

background: essential oils are found to have multiple active components which can show in vitro cytotoxic action against various cancerous cell lines. this study reports the in vitro cytotoxic effects of the essential oil from artemisia absinthium l. (asteraceae) growing wild in iran. methods: water-distilled essential oil of a. absinthium collected from ardabil, north-western iran, was examine...

Purpose: To explore the functions and regulatory mechanisms of synaptopodin-2 (SYNPO2) in cervical cancer progression.
 Methods: Normal cell lines (Ect1/E6E7) (HeLa, SiHa, C-33A, CaSki) were cultured. The pcDNA3.1 vector overexpressing SYNPO2, a negative control (vector), blank (control) transfected into HeLa SiHa cells. Protein expression from normal was examined by western blot. Cell via...

Poliomyelitis, an acute viral infectious disease caused by poliovirus, still remains a public health problem in developing countries. Despite the global effort to eradicate polio, continuing the polio immunization with a potent and safe vaccine is essential. For accurate vaccine evaluation, three types of cell lines including Hela, Hep2C and Vero were evaluated and compared using two methods of...

there have been efforts to overcome the problem in treatment of cancer using medicinal plants. it has been shown that citrus essential oil of contains different terpens with antitumor activities. in this study we sought to determine the cytotoxicity of essential oils of iranian citrus limon (l.), c. medica (l.), c. sinsensis (l.) peels on cancer cell lines. essential oils were prepared by hydro...

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...
