Cytotoxic effect of nitric oxide on human hematological malignant cells.

Effects of aqueous saffron extract on nitric oxide production by two human carcinoma cell lines: Hepatocellular carcinoma (HepG2) and laryngeal carcinoma (Hep2)

Objective: A number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. It has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (NO) production. These data suggest that the cytotoxic effect of saffron extra...

Sildenafil Effect on Nitric Oxide Secretion by Normal Human Endometrial Epithelial Cells Cultured In vitro

P-96: Survey of In Vitro Effect of Noscapine on Nitric Oxide Secretion of Human Endometrial Stromal Cell

Background: Noscapine is cough suppressant drug with cell inhibitory effect. It is introduced for anti-cancer treatment. The aim of present study was to determine in vitro noscapine effect on nitric oxide (NO) secretion by human endometrial stromal cells. Materials and Methods: Human endometrial biopsies (n=8) were obtained in sterile condition and were chopped mechanically and digested by enzy...

P-113: Survey of In Vitro Effect of Resveratrol on Nitric Oxide Secretion of Human Endometrial Epithelial Cells

Background: Resveratrol is a natural polyphe- nolic compound, synthesized by plants as a phytoalexin and protects against ultraviolet radiation and fungal infection. Nitric oxide is formed from L-arginine through nitric oxide synthases (NOS), a group of enzymes that structurally resemble cytochrome P-450 reductase. In females, circulating NO is increased during follicle development and decrease...

Effect of 17-? Estradiol on the Expression of Inducible Nitric oxide Synthase in Parent and Tamoxifen Resistant T47D Breast Cancer Cells

Indirect evidence suggests that estrogen is involved in the etiology of breast cancer. Estrogen is also thought to modulate nitric oxide (NO) in human breast tumor tissue via regulation of inducible nitric oxide synthase (iNOS). Objectives of this study were to determine whether estradiol (E2) affects iNOS expression level in breast cancer cells and to study the effect of various concentrations...
