The effect of crocetin (C20H24O4) on methylcholanthrene- (MCA-) induced uterine cervical cancer in mice was studied in this paper. After the mice were treated orally with crocetin, maleic dialdehyde (MDA), polymorphonuclear cells (PMN), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) were examined by ELISA or immunohistochemistry. The inducible nitric oxide synthase (iNOS) activatio...
Crocetin, a carotenoid compound derived from saffron, has long been used as a traditional ancient medicine against different human diseases including cancer. The aim of the series of experiments was to systematically determine whether crocetin significantly affects pancreatic cancer growth both in vitro and/or in vivo. For the in vitro studies, first, MIA-PaCa-2 cells were treated with crocetin...
We investigated the cytotoxic activities of crocin and crocetin, 2 major carotenoids isolated from the stigma of Crocus sativus (saffron), on 5 human cancer cell lines and proposed their possible anticancer mechanisms. Crocetin, a glycosylated carotenoid, showed approximately 5- to 18-fold higher cytotoxicity than crocin, a carboxylic carotenoid (IC50 of 0.16-0.61 mmol/L for crocetin vs. 2.0-5....
OBJECTIVE The present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of Crocus sativus L. (saffron) using mice in two different regimens of acute and sub-acute administration. MATERIAL AND METHODS In acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p.) were evaluated using...
OBJECTIVE To investigate the antifibrotic effects of crocetin in scleroderma fibroblasts and in sclerotic mice. METHODS Skin fibroblasts that were isolated from three systemic scleroderma (SSc) patients and three healthy subjects were treated with crocetin (0.1, 1 or 10 μM). Cell proliferation was measured with an MTT assay. Alpha-smooth muscle actin was detected via an immunohistochemical me...
Crocetin, a constituent of saffron, has been shown not only to prevent reactive oxygen species-induced hepatotoxicity and genotoxicity but also to increase whole-body oxygen consumption and survival. The present study was to determine whether crocetin has beneficial effects on cardiac injury caused by hemorrhagic shock and resuscitation in rats. Anesthetized rats were bled to reduce mean arteri...
To develop an artificial photosynthesis model, the anionic water-soluble carotenoid dye crocetin was electrostatically immobilized onto the surface of cationic surfactant cetyltrimethylammonium bromide (CTAB) micellar medium including Mg chlorophyll-a and b (MgChl-a and b) (Cro/MgChl), and its photophysical properties were studied using UV-vis absorption and fluorescence spectroscopy. The fluor...
BACKGROUND/AIM Crocetin is a readily bioavailable and bioactive compound extracted from Saffron. Previous studies indicated its various biomedical properties including antioxidant and anti-coagulation potencies. However, its effect on inflammation, notably within the cardiovascular system, has not been investigated yet. In the present study, we utilized human umbilical vein endothelial cell (HU...
This study aims to investigate the protective role of crocetin, a natural antioxidant, against cytotoxicity produced by exposure to norepinephrine (NE) in primary cultured rat cardiac myocytes. Reactive oxygen species (ROS) and Ca(2+) in cells were evaluated by fluorescence microplate reader using 6-carboxy-2',7'-dichlorofluorescein and fluoro-3-acetoxymethyl ester, respectively. Lipid peroxida...
Crocetin is a carotenoid that is the aglicone of crocin, which are found in saffron stigmas (Crocus sativus L.) and gardenia fruit (Gardenia jasminoides Ellis). In this study, we investigated the effects of crocetin on retinal damage. To examine whether crocetin affects stress pathways, we investigated intracellular oxidation induced by reactive oxygen species, expression of endoplasmic reticul...
