dytogenetic analysis of hela and chang cells
based on the evaluation of two human cell lines, hela and chang, abeuploidy and several marker chromosomes were found in both cells. the morphological characteristic of marker chromosomes of chang cells was distinctly different from hela. certain submetacentric marker chromosome was frequently present among 80% of marker chromosomes of chang cells which distinguished this line from hela, which ...
متن کاملRadiosensitizing effects of gemcitabine on aerobic and chronically hypoxic HeLa and MRC5 cells in-vitro
Background: Gemcitabine (2′, 2′-difluoro-2′- deoxycytidine, an analogue of deoxycytidine) is a relatively new drug with wide range of anti-cancer activity. In this study, radiosensitizing effects of gemcitabine was investigated on HeLa and MRC5 human originated cell lines under both chronically hypoxic and normoxic conditions using the micronucleus (MN) assay. Materials and Methods: F...
متن کاملEvaluation of the effects of paederus beetle extract and gamma irradiation on HeLa cells
Objective(s):Cervical cancer is a malignancy that is the second most common cause of death from cancer in women throughout the world. Paederus beetle (Paederus fuscipes) extract (PBE), contains bioactive compounds such as pederine which has cytotoxic properties and blocks DNA and protein synthesis at very low concentrations. In this investigation we tried to determine the effects co-treatment w...
متن کاملSubcompartments in Intact HeLa Cells
Two recombinant aequorin isoforms with different Ca 2 1 affinities, specifically targeted to the endoplasmic reticulum (ER), were used in parallel to investigate free Ca 2 1 homeostasis in the lumen of this organelle. Here we show that, although identically and homogeneously distributed in the ER system, as revealed by both immunocytochemical and functional evidence, the two aequorins measured ...
متن کاملKnockdown of mitofilin inhibits autophagy and facilitates starvation-induced apoptosis in HeLa cells
Objective(s): Mitofilin contributes to the maintenance of mitochondrial structure and functions. This study was undertaken to determine the mechanisms underlying its regulation of apoptosis. Materials and Methods: Mitofilin was knockdowned by specific short hairpin RNA (shRNA) and the stable HeLa cell clone was selected. The autophagy a...
