BACKGROUND AND AIM The human CD24 antigen is a small heavily glycosylated cell surface protein, which is expressed in a large variety of solid tumors,including gastric cancer. Enriched on the surface of many tumor cells,CD24 promotes tumor growth,invasion and metastasis and confers resistance to some chemotherapeutic drugs.In this study, we investigated the possible effect of CD24 suppression o...

objective: acorus calamus (a. calamus) has been used as a medicinal plant in asia for its effects on digestive system for the last 2000 years. to investigate the anti-cancer activity of rhizome of a. calamus, the ethanolic and methanolic extracts and essential oil of the rhizome were prepared and their effects were assessed on human gastric cancer cell line (ags). materials and methods: the via...

AIM In this paper effect of combinational usage of calprotectin and etoposide on AGS cell line is studied. BACKGROUND Application of combined toxic agents such as etoposide and cicplatin are commonly used for chemotherapy purposes. As a matter of fact, calprotectin and etoposide were both applied on human gastric adenocarcinoma cell line (AGS) as antitumor agents. Both calprotectin and etopos...

Abnormal expression of the kallikrein (KLK) family of serine proteases closely correlates with onset, progression, and prognosis of endocrine gland-related malignant tumors. The aim of this study was to evaluate how downregulation of KLK12 influenced cell cycle and proliferation of the AGS gastric cancer cell line. KLK12 was detected by western blot in GES-1 normal gastric epithelial and AGS ce...

AIM To investigate the response to hyperthermia and chemotherapy, analyzing apoptosis, cytotoxicity, and cisplatin concentration in different digestive system cancer cells. METHODS AGS (gastric cancer cell line), Caco-2 (colon cancer cell line) and T3M4 (pancreatic cancer cell line) were treated by cisplatin and different temperature setting (37 °C to 45 °C) either in isolation, or in combina...

BACKGROUND Gastric cancer is a common and highly lethal malignancy in the world, but its pathogenesis remains elusive. In this study, we focus on the biological functions of CDK-associated Cullin1 (CAC1), a novel gene of the cullin family, in gastric cancer, which may help us to further understand the origin of this malignancy. METHODS The AGS and MGC803 gastric cancer cell lines and the GES-...

objective: curcumin, is the active component in turmeric (curcuma long). this agent induces apoptosis via inhibiting various signaling pathways. however, its poor aqueous solubility prevents its widespread application. in this study, dendrosomes with water-solubility, nano-sized dimensions and nontoxic properties, was used for curcumin delivery to cells. materials & methods: in the present...
