بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...
abstract background: the aims of this study were to assay the activity of adenosine deaminase (ada) in estrogen receptor positive (mcf-7) and negative (mda-mb468) breast cancer cell lines. methods: mda-mb468 and mcf-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-lm diethylstilbestrol (des), complete medium in the presence and absence of 111m t...
objective: the objective of this study was to investigate inhibition and anti-cancer effects of linoleic acid on the mcf-7 and mda-mb-231 human breast cancer cells. materials and methods: cell lines human breast cancer mcf-7 (gdc055) and mda-mb-231 (htb-26) cell lines were obtained from atcc. mcf-7 estrogen receptor positive human breast cancer cell line and the estrogen receptor negative huma...
Background and purpose: Today cancer is considered as one of the leading causes of death worldwide. An impressive number of modern drugs used in cancer treatment are isolated or derived from natural sources based on their use in traditional medicine. Cornus mas L. (Cornaceae) has medicinal applications in treating a wide range of diseases such as cancer. This study was designed to evaluate the ...
background: opticin, as a member of small leucine rich proteoglycans (slrps), mainly expressed in human eyes. it is also expressed in human brain, ligament, liver and skin, but at lower levels than the eyes. in the present study, expression of opticin was studied in a variety of human cancer cell lines. materials and methods: in this basic study, human cancer cell lines including, a-172 (brain ...
background: increasing the complexity in modern radiotherapy techniques have increased the delivery time lowering consequently the treatment efficacy. through simulating the delivery time delay encountered in such techniques, its’ effect on two cancer cell lines and the compensating doses given to prevent such effect was investigated. materials and methods: f10b16 and 4t1 cancer cell lines were...
Received: 3 April, 2009 Accepted: 5 Oct, 2009 Abstract Background & Aim: Nowadays, different medical approaches are used for the treatment of cancers, but in most cases they are not effective or have serious side-effects. This has prompted scientists to look for more effective drugs with less toxicity. This study was to evaluate the cell cytotoxicity effect of fractions isolated from Pleurotu...
Background: Human cancer cell lines express human choriogonadotropin (hCG), its subunits and derivatives, regardless of their origin and type. It appears that hCG is a common phenotype in human cancer cell lines. In this research, the effects of hCG targeting monoclonal antibodies (7D9, T18H7 and T8B12) on human cancer cell lines were evaluated. Methods: Monoclonal antibody secreting hy...
Background and purpose: Incidence of breast cancer is increasing day by day. Scientists are interested in the effects of inhibition of breast cancer cell on treatment of this cancer. The aim of this study was to determine IC50 of doxorubicin in 24 hours on cell lines MCF-7 and MDA-MB-231 and the expression of heat shock protein HSP90α as a factor in the cell before and after 24 hours expo...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
