BACKGROUND This study aimed to develop a novel tumor-specific promoter gene linking sodium iodide symporter (NIS) gene to specifically target hepatocellular carcinoma in a mouse tumor model. MATERIALS AND METHODS A tumor-specific chimeric promoter for alpha-fetoprotein gene (AFP) was combined with hepatitis B virus (HBV) enhancer II to investigate radioiodine uptake in vitro and in vivo in he...
The aim of the study was to test and compare the cytotoxic potential of two synthetic oestrogens: diethylstilboestrol (DES) and ethinyloestradiol (EE2) and two androgens: testosterone propionate (TP) and trenbolone (TREN) on two cell lines. The fibroblast cell line Balb/c 3T3 and the hepatoma cell line HepG2 were selected. To get more insight into the mode of toxic action, four methods were use...
This study demonstrated that glycyrrhizate (GAS) could protect HEPG2 cells against damage and apoptosis induced by H2O2 (1600 μM, 4 h). Cell viability assay revealed that GAS was noncytotoxity at concentration 125 µg/mL, and GAS (5 μg/mL, 25 μg/mL, and 125 μg/mL) protected HepG2 cells against H2O2-induced cytotoxicity. H2O2 induced the HepG2 cells apoptosis, obvious morphologic changes were obs...
Exosomes are membrane-derived extracellular vesicles that have recently been recognized as important mediators of intercellular communication. In the present study, we investigated the effects of exosomes derived from SW480 colorectal cancer cells in recipient HepG2 hepatocellular cancer cells. We demonstrated that SW480-derived exosomes were taken up by the recipient HepG2 cells via dynamin-de...
Hepatocellular carcinoma is the most common type of liver cancer. The risk of hepatocellular carcinoma for type 2 diabetic patients is greater than that for non-diabetic individuals although the mechanism is unclear. The cancer suppressor resveratrol inhibits cancer cell proliferation partly through the STAT3 signaling pathway. However, the effects of resveratrol on STAT3 in high glucose-expose...
An in vitro system for production of hepatitis B virus (HBV) was established by infection of human hepatoma (HepG2) cells. HBV particles obtained from the serum of a chronic hepatitis B surface antigen (subtype ad) carrier were used to inoculate HepG2 cells. HBV envelope and core proteins were synthesized de novo by the infected cells and secreted into the medium 3 to 6 days postinfection. Vira...
HepG2 cells were stably transfected with human caveolin-1 (HepG2/cav cells). Transfection resulted in expression of caveolin-1 mRNA, a high abundance of caveolin-1 protein, and the formation of caveolae on the plasma membrane. Cholesterol efflux from HepG2/cav cells was 280 and 45% higher than that from parent HepG2 cells when human plasma and human apoA-I, respectively, were used as acceptors....
Hypoxia and oxidative stress are critical factors in carcinogenesis and exist throughout cancer development; however, the underlying mechanisms are far from clear. Here, for the first time to our knowledge, we reported that neuroglobin (Ngb), an intracellular hexa-coordinated globin serving as an oxygen/reactive oxygen species (ROS) sensor, functions as a tumor suppressor in hepatocelluar carci...
مقدمه: درمان فتودینامیکی یک روش نسبتاً جدید برای درمان سرطان و برخی از ضایعات غیر بدخیم است. درمان فتودینامیکی برای از بین بردن سلول های بدخیم از نور و داروی حساس به نور استفاده می کند. هدف از این مطالعه بررسی اثر های سمی مادۀ حساس به نور متیلن بلو در شکل غیر فعال و فعالش (القاء شده توسط لیزر) بر روی ردۀ سلول های سرطانی کبد انسان ( hepg2 ) و فیبروبلاست های نرمال انسانی بود. روش بررسی: سلول های...
objective: this study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (hcc) cell line (hepg2). materials and methods: in this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with hepes buffer and sonication at 60% amplitu...
