CD40 binding produces multifaceted growth signals in normal and malignant B cells, whereas its physiological role is less well characterized in epithelial cancers. We examined the growth outcome of CD40 ligation in human breast cancer cells, using CD40 (T47D and BT-20) and CD40-negative (MCF-7, ZR-75–1) cell lines as defined by flow cytometric analysis, immunohistochemistry, and reverse transcr...
CD40 binding produces multifaceted growth signals in normal and malignant B cells, whereas its physiological role is less well characterized in epithelial cancers. We examined the growth outcome of CD40 ligation in human breast cancer cells, using CD40+ (T47D and BT-20) and CD40-negative (MCF-7, ZR-75-1) cell lines as defined by flow cytometric analysis, immunohistochemistry, and reverse transc...
برای درمان سرطان استفاده از ترکیباتی گیاهی و جانوری مختلفی در دست بررسی است. در پژوهش حاضر نیز اثر ضدسرطانی جلبک قرمز Laurencia caspica که یکی از ماکروجلبکهای اکوسیستم دریای خزر است، مورد مطالعه قرار گرفته است. از این رو اثر سمیت و تغییر بیان ژن سرکوبگر nm23 به وسیله تیمار با عصاره جلبک L. caspica ارزیابی شد. به این ترتیب که جلبک L. caspica از سواحل رامسر جمعآوری شد و عصاره هیدروالکلی آن به ک...
The dense layer of fibroblasts that accumulate around malignant breast epithelial cells (i.e., desmoplastic reaction) arises from the breast adipose tissue and provides structural and biochemical support for breast cancer. We report herein a number of epithelial-stromal interactions responsible for desmoplastic reaction in breast cancer using cultured 3T3-L1 murine fibroblasts and human adipose...
A new group of 4-(Imidazolylmethyl) quinoline derivatives possessing a methylsulfonyl COX-2 pharmacophore at the para position of the C-2 phenyl ring were designed and synthesized as selective COX-2 inhibitors and in-vitro anti breast cancer agents. In-vitro COX-1 and COX-2 inhibition studies showed that all the compounds were potent and selective inhibitors of the COX-2 isozyme with IC50 value...
