Background: Lactoferrin (Lf) is a glycoprotein, a member of the transferrin family.From ten known mechanisms of anti-cancer chemoperotecive compounds, Lf alone, has six of these functions and inhibits cancer. In this study, the effect of lactoferrin purified from bovine colostrum was studied as an anti-cancer agent on esophageal cancer cell line. Materials and Methods: Bovine colostrum were ...

Background: Cumin (Cuminum cyminum L. [family Apiaceae]) seed essential oil is reported to have antiseptic activity. Until now the antiviral properties of cumin seed extracts on viruses such as herpes simplex virus-1 (HSV-1) have not been studied. The objective of this study was to investigate the in vitro effects of aqueous, methanolic and hydroalcoholic extracts of cumin seed on HSV-1 growth ...

background: ß-carbolines, harmaline and harmine, are the major alkaloids presenting in the seeds of the peganum harmala l. these alkaloids are known as herbal active principals with potential use in pharmaceutical and medicine. objectives: to assess the growth inhibitory effect of phyto-alkaloids, harmaline and harmine, on cancer cell lines. methods: the p. harmala l.’s alkaloids were extracted...

cancer cell-stromal cell interaction plays a crucial role in the growth and invasion of tumor cells of various organs. it has been recently suggested that adipocytes and preadipocytes, two specific types of stromal cells, affect the biological behavior of variety of breast cancer cell lines. in spite of few investigations, there is a controversy in the literatures about the effects of adipocyte...

Background: Usually, chemoradiotherapy can be used for the treatment of locally advanced colorectal cancer (CRC) before surgery. On the other hand, some studies have shown that fractional radiation of tumor cells leads to chemoresistance. The aim of this study was to evaluate the chemoresistance of radioresistant sub-line (RR sub-line).Methods: This study was done in Hamadan University of...

background: hyperglycemia is one of the important featurs of diabetes. in cell culture studies different methods are used to mimic the hyperglycemia condition. in this study we investigate response of human liver cancer cell line (hepg2) to high insulin, high glucose, and high insulin/ high glucose medium exposure. methods: hepg2 cells were settled in dmem+0.1% fbs or dmem free-serum medium wit...

Background and objectives: Prosopis farcta has been used as a traditional herbal medicine for treating diabetes mellitus.The aim of this study was investigating the antidiabetic mechanisms of infusion extract of P. farcta and discovering the active extract for the first time. Methods: Six different extracts of P. farcta were ...

Background: Chemo-immunotherapy is one of the new achievements for treatment of cancer, by which the success of anti-cancer therapy can be increased. In vitro studies have been shown that Arteether (ARE) induces apoptosis in tumor cells, but not in normal cells. Objective: To investigate the cytotoxic and immunomodulatory properties of Arteether in-vivo and in-vitro. Methods: In this study, we ...

Introduction: The mechanism of putative cytotoxicity of 4-[3-(cyclopentyloxy)-4-methoxyphenyl]-2-pyrrolidone (rolipram), a specific phosphodiesterase-4 (PDE4) inhibitor, on glioblastoma multiforme (GBM) is almost unknown. This study aimed to investigate the role of protein kinase B (Akt) pathway in the cytotoxic effect of rolipram on human GBM U87 MG cell line and tumor-initiating cells (TICs) ...
