سابقه و هدف: سرطان معده یکی از شایع‌ترین و کشنده‌ترین بدخیمی‌ها در جهان است. اسید رتینوئیک تمام ترانس (ATRA) به عنوان القاکننده‌ی تمایز در درمان بسیاری از سرطان‌ها و به طور ویژه در درمان لوسمی پرومیولوتیک حاد (APL) استفاده می‌شود. مسیر پیام‌رسانی سلولی Notch نقش مهمی در حفظ تعادل میان تکثیر سلولی و آپوپتوز ایفا می‌کند. فعالیت نابه‌جای این مسیر در توسعه و پیشرفت بسیاری از بدخیمی‌ها از جمله سرطا...
AIM Helicobacter pylori (H pylori) is associated with increased gastric inflammatory and epithelial expression of macrophage migration inhibitory factor (MIF) and gastric epithelial cell proliferation. This study aimed at determining whether H pylori directly stimulates release of MIF in monocytes, whether the cag pathogenicity island (PAI) is involved for this function, and whether MIF stimula...
We evaluated miR-371-5p expression in gastric cancer (GC) tissues and its influence on the expression of downstream genes, especially SOX2. MiR-371-5p expression (measured using qRT-PCR) was upregulated in GC tissues and correlated positively with TNM staging and lymph node (LN) metastasis. MiR-371-5p expression was higher in human GC cell lines (AGS, MKN-28, BGC-823, MGC-803, SGC-7901 and MKN-...
objective: verotoxin is a member of shiga toxin family. this family contains ab protein toxins with an enzymatic (a) and a binding (b) compartment. cells that have receptor (gb3) are sensitive to cytotoxic effects of toxin. it has been shown that various tumor cells have gb3 receptor and are selectively sensitive to apoptotic effect of verotoxin. studies on tumor cell lines and laboratory anima...
objective: today, special attention is paid to the use of zirconium dioxide nanoparticle (nano-zro2), a neutral bioceramic metal, particularly for drug and gene delivery in medicine. however, there are some reports implying that use of nano-zro2 is associated with cytotoxic effects like inhibiting the cell proliferation, dna damage and apoptosis. in the present study, we examined whether nano-z...
BACKGROUND ErbB receptors and their cognate ligands are implicated in cancer progression. Their expression in gastrointestinal cancer, however, has not been systemically studied. MATERIALS AND METHODS The expression of four ErbB receptors and a panel of ErbB ligands were determined by reverse transcription-PCR in two gastric (TMK1, MKN-45) and two colon (SW1116, HT-29) cancer cell lines. Cell...
Aspirin-induced apoptosis is one of the important mechanisms for its antitumour effect against gastric cancer. We aimed at investigating the involvement of bcl-2 family members in the apoptotic pathway in gastric cancer. Gastric cancer cell line AGS and MKN-45 were observed as to cell growth inhibition and induction of apoptosis in response to treatment with aspirin. Cell proliferation was meas...
