objective(s): artemisia is a genus of herbs and small shrubs forms an important part of natural vegetation in iran. it has been reported that several artemisia species possess anti-proliferative effects. considering the value of this genus in anti-cancer researches we have chosen artemisia biennis for cytotoxic and mechanistic studies. materials and methods:in this study we have investigated th...
conclusions collectively, the v. pumilum extracts showed remarkable cytotoxic activity and merit further investigation as anticancer agents. results the ch2cl2 fraction of v. pumilum showed a potent dose-related inhibitory effect on cell viability. the ch2cl2 fraction showed ic50 values of 8.3 and 12.5 µg/ml in the k562 and hl-60 cell lines, respectively. a sub-g1 peak in the flow cytometry his...
background and objective: vascular endothelial growth factor (vegf) is a cytokine which is overexpressed in many malignant cancers including leukemia. vegf plays an important role in tumor invasion and metastasis. determination of the pattern of vegf expression in human leukemic cell lines could be useful not only in screening of new antileukemic agents but also to study the mechanism of their ...
Background: Dimethyl Sulfoxide (DMSO) is a solvent most broadly used as a cryopreservative agent. Antitumor effects of DMSO is a recently recognized phenomenon. In this study, cytotoxic effects of DMSO on human monocytes and T leukemic cell lines has been investigated in vitro. Methods: Human leukemic T cells (Molt-4 and Jurkat) and monocytes (U937 and THP1) were cultured in complete RPMI medi...
Background and Objective: Vascular endothelial growth factor (VEGF) is a cytokine which is overexpressed in many malignant cancers including leukemia. VEGF plays an important role in tumor invasion and metastasis. Determination of the pattern of VEGF expression in human leukemic cell lines could be useful not only in screening of new antileukemic agents but also to study the mechanism of their ...
Background: As a T helper type 1 (Th1) derived cytokine, Interferon gamma (IFN-γ) is an important regulator of inflammatory immune responses. Furthermore, IFN-γ plays an essential role in defense against tumors and intracellular pathogens. This study was designed to assess the pattern of IFN-γ production in human leukemic (Jurkat and Molt-4) T cell lines in vitro. Methods: Ju...
considering multiple reports on cytotoxic activity of the artemisia genus and its phytochemicals, in the current study a. armeniaca lam. and the three components isolated from the plant were subjected to cytotoxic studies. analytical fractionation of a. armeniaca aerial parts for the first time was directed to the isolation of 7-hydroxy-8-(4-hydroxy-3-methylbutoxy) comarin (armenin), 8-hydroxy-...
background: beta-adrenergic blocking agents have been broadly used for treatment of many cardiovascular diseases such as arterial hypertension and ischemic heart failure. anti-tumoral, anti-inflammatory and anti-angiogenesis effects of propranolol (a non-selective beta-adrenergic blocker) have been shown. angiogenesis (replenish of the pre-existing vascular networks) plays a critical role in so...
Background: Leukemia is a malignant proliferative disorder of the hematopoietic cells. The important role of angiogenesis in leukemia has been reported by several studies. Matrix metalloproteinases (MMPs) are a large group of endopeptidases which degredate the extracellular matrix and play an important role in angiogenesis. Objective: The present study was conducted to evaluate the patterns of ...
