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...

Objective: Perovskia abrotanoides Karel, belongs to the family Lamiaceae and grows wild alongside the mountainous roads inarid and cold climate of Northern Iran. The anti-tumor activity of P. abrotanoides root extract has been shown previously. This study was designed to examine in vitro anti-proliferative and pro-apoptotic effects of flower extract of P. abrotanoides on MCF-7 and Hela cell lin...

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...

HeLa cells are the archetypal tissue culture cell line for the preparation of mammalian cell-free systems. These cells, derived from a cervical carcinoma, have been maintained in culture since the late 1940s. They grow with a doubling time of ∼24 h and can be cultured in medium containing fetal bovine serum (optimal serum for growth) or medium containing horse serum (in which they grow more slo...

background: functional defects in mitochondria are involved in the induction of cell death in cancer cells. the process of programmed cell death may occur through the mechanisms of apoptosis. several potential lead molecules such as camptothecin (cpt) and its analogues have been isolated from plants with anticancer effect. the aim of the present study was to understand the necrotic effect versu...

Background Polysaccharides extracted from fungus that have been used widely in the food and drugs industries due to biological activities. Objective The objective of the present study was to investigate the tumor-suppressive activity and mechanism of a novel polysaccharide (SAP) extracted from Sarcodon aspratus. Methods The SAP was extracted and purified using Sepharose CL-4B gel from S. as...

The number of mitochondria per cell varies substantially from cell line to cell line. For example, human HeLa cells contain at least twice as many mitochondria as smaller mouse L cells. This protocol starts with a washed cell pellet of 1-2 mL derived from ∼10⁹ cells grown in culture. The cells are swollen in a hypotonic buffer and ruptured with a Dounce or Potter-Elvehjem homogenizer using a ti...

A putative HeLa cell culture line was discovered to be contaminated with mouse cells by examination of agarose gel profiles of restriction endonuclease digests of mitochondrial DNA. The contamination was confirmed by karyotypic analysis, and by observation of the mouse satellite band in an analytical buoyant density centrifugation of total cellular DNA. Restriction endonuclease analysis of mito...
