background: tumour suppressor genes such as tp53, brca1 and rad51 are involved in dna repair and their malfunctions result in genomic instability and cancer. wild type (wt) tp53 binds to brca1and rad51 in vivo and in vitro. however, mutated tp53 in tumours can interfere with wt tp53 function. we studied how mutation of tp53 in mda-mb-468 cell line could affect its binding capacity and interfere...

herpes simplex virus types 1 (hsv-1) and 2 (hsv-2) are members of the herpesviridae family. about 40% to 80% of the world populations are infected with hsv and its prevalence is high in iran. the high prevalence of this virus in the community and the ability of the virus in causing fatal diseases among immunocompromised patients, have encouraged studies to be performed on hsv and suitable cell ...

objective(s): glioblastoma multiforme (gbm) is one of the most lethal forms of human cancer and temozolomide (tmz) is currently part of the standard treatment for this disease. combination therapy using natural substances can enhance the anti-cancer activity of tmz. the purpose of this study was to evaluate the effect of tmz in combination with thymoquinone (tq) on human gbm cell line (u87mg). ...

background: immunotoxins are comprised of both the cell targeting and the cell killing moieties. we previously established a new immunotoxin, i.e. shiga toxin granulocyte macrophage-colony stimulating factor (stxa1-gm-csf), comprises of catalytic domain of stx, as a killing moiety and gm-csf, as a cell targeting moiety. in this study, the ability of the immunotoxin to induce apoptosis and doubl...

background and objective: pneumocystis pneumonia (pcp) has been historically the most prevalent opportunisticinfection in patients infected with the human immunodeficiencyvirus. culture of the organism has not been faced with suitable success in artificial media, while various results have been reported for cell culture media. the aim of this study was proliferation of pneumocystis carinii on t...

abstract the antineoplastic activities of alcoholic and aqueous extracts of the roots, stems and leaves of isatis campylocarpa an endemic species of the brassicaceae family from iran, investigated on the growth of jurkat as an acute lymphocytic leukemia cell line, k562 as a chronic myelogenous leukemia cell line and fen as a bladder cancer cell line using colorimetric assay. results showed that...

Background and Aims: During the last years a new Foreskin cell line strain (RFSC) has been isolated, characterized and stored in a representative cell bank stock in liquid nitrogen as a part of HCB (Human Cell Bank) development program in Razi institute. Materials and Methods: The cell population was serially passaged for mass production purpose based on WHO schedule .The controls on pool sampl...

apoptosis, or programmed cell death, is an essential physiological process that plays a critical role in development and tissue homeostasis. caspases, a family of cysteine-dependent aspartate-directed proteases, play a critical role in the initiation and execution of apoptosis. in this study, cytotoxicity and apoptogenic effect of 2-phenyl 4-carboxamide derivatives were evaluated in sknmc (huma...
