Crocin, a component of saffron spice, is known to have an anticancer activity. However, the targets of crocin are not known. In this study, crocin was found to inhibit the proliferation of HCC70, HCC1806, HeLa and CCD1059sk cells by targeting microtubules. Crocin depolymerized both the interphase and mitotic microtubules of different cancer cells, inhibited mitosis and induced multipolar spindle formation in these cells. In vitro, crocin inhibited the assembly of pure tubulin as well as the assembly of microtubule-associated protein rich tubulin...

Saffron (SAF), the dried stigmas of Crocus sativus is commonly used for flavouring and coloring food. Studies on bioactivity of SAF have demonstrated its in vivo antioxidant activity. The aim of our study was to assess the impact of SAF intake on γ-radiation (RAD) induced: (a) chromosomal damage, (b) oxidative stress in liver and brain and (c) histopathological effects in the intestinal cells and male germ cells in mice. Freeze-dried aqueous extract of SAF was used for the experiments. Our preliminary cell-free DNA nicking assay using pBR322 DNA revealed protective effects of freeze-dried SAF extract against hydroxyl radical induced DNA damage...

The aim of the present study is to investigate the effect of a natural compound crocin, one of the active components of saffron, on human multiple myeloma cells. Crocin effectively suppressed constitutive STAT3 activation, translocation of STAT3 to the nucleus, and its target gene expression. The suppression of STAT3 was mediated through the inhibition of activation of protein tyrosine kinases JAK1, JAK2 and c-Src. We found that crocin induced the expression of SHP-1, a tyrosine protein phosphatase, and pervanadate treatment reversed the crocin-induced downregulation of STAT3, suggesting the involvement of a protein tyrosine phosphatase...

As an aromatic and colorful plant of substantive taste, saffron (Crocus sativus L.) owes such properties of matter to growing class of the secondary metabolites derived from the carotenoids, apocarotenoids. Regarding the critical role of microRNAs in secondary metabolic synthesis and the limited number of identified miRNAs in C. sativus, on the other hand, one may see the point how the characterization of miRNAs along with the corresponding target genes in C. sativus might expand our perspectives on the roles of miRNAs in carotenoid/apocarotenoid biosynthetic pathway...

For centuries, spices have been consumed as food additives or medicinal agents. However, there is increasing evidence indicating the plant-based foods in regular diet may lower the risk of neurodegenerative diseases including Alzheimer disease. Spices, as one of the most commonly used plant-based food additives may provide more than just flavors, but as agents that may prevent or even halt neurodegenerative processes associated with aging. In this article, we review the role and application of five commonly used dietary spices including saffron turmeric, pepper family, zingiber, and cinnamon...

Diabetic retinopathy (DR) is a serious microvascular complication of diabetes mellitus that is closely associated with the degeneration and loss of retinal ganglion cells (RGCs) caused by diabetic microangiopathy and subsequent oxidative stress and an inflammatory response. Microglial cells are classed as neurogliocytes and play a significant role in neurodegenerative diseases. Over-activated microglial cells may cause neurotoxicity and induce the death and apoptosis of RGCs. Crocin is one of the two most pharmacologically bioactive constituents in saffron...

INTRODUCTION: There is growing interest in the use of curcumin, a plant polyphenol with potent anti-inflammatory, anti-oxidant, and neuroprotective properties, as a novel antidepressant. Clinical trials have yielded conflicting conclusions pertaining to its effectiveness in depression. A meta-analysis of the topic, which has not been done until now, is therefore necessary to summarize current evidence and generate hypotheses for further research. METHODS: Using the keywords [curcumin OR diferuloylmethane OR curcuminoid OR turmeric OR Indian saffron] AND [depression OR MDD OR suicide], a preliminary search on the PubMed, Ovid, Clinical Trials Register of the Cochrane Collaboration Depression, Anxiety and Neurosis Group (CCDANTR), and Cochrane Field for Complementary Medicine database yielded 2081 articles published in English between January 1, 1960, and August 1, 2016...

Schizophrenia is a chronic mental disease that affects nearly 1% of the population worldwide. Several lines of evidence suggest that the dopaminergic (DAergic) system might be compromised in schizophrenia. Specifically, the mixed dopamine (DA) D1/D2 receptor agonist apomorphine induces schizophrenia-like symptoms in rodents, including disruption of memory abilities. Crocins are among the active components of saffron (dried stigmas of Crocus sativus L. plant) and their implication in cognition is well documented...

Safranal, a major constituent of saffron, possesses antioxidant and anti-apoptotic properties showing considerable neuroprotective effects. However, whether safranal shows therapeutic effect on Parkinson's disease (PD) remains unknown. In this study, we aimed to investigate the potential effect of safranal on PD using an in vitro model of PD induced by rotenone. We found that safranal significantly inhibited rotenone-induced cell death in a dose-dependent manner. Moreover, safranal also markedly suppressed the reactive oxygen species (ROS) generation and cell apoptosis induced by rotenone...

Crocin (CRO) and safranal (SAF) are bioactive constituents of saffron (dried stigma of Crocus sativus flower), an expensive spice with medicinal properties. Aqueous extract of saffron is known for its antigenotoxic effect against environmental genotoxins/carcinogens. However, there is need to identify saffron constituents responsible for this antigenotoxic effect. The aim of our investigation was to ascertain the role of CRO and SAF as inhibitors of in vivo genotoxic stress. For this purpose, Swiss albino mice were pretreated with CRO (50-mg/kg body weight (bw))/SAF (0...

The formation of bilayer-based lyotropic liquid crystals and vesicle dispersions by phospholipids in a range of protic ionic liquids has been investigated by polarizing optical microscopy using isothermal penetration scans, differential scanning calorimetry, and small angle X-ray and neutron scattering. The stability and structure of both lamellar phases and vesicle dispersions is found to depend primarily on the underlying amphiphilic nanostructure of the ionic liquid itself. This finding has significant implications for the use of ionic liquids in soft and biological materials and for biopreservation, and demonstrates how vesicle structure and properties can be controlled through selection of cation and anion...

Alzheimer's disease (AD) is the most common form of dementia, in which the death of brain cells causes memory loss and cognitive decline. Several factors are thought to play roles in the development and course of AD. Existing medical therapies only modestly alleviate and delay cognitive symptoms. Current research has been focused on developing antibodies to remove the aggregates of amyloid-β (Aβ) and tau protein. This approach has achieved removal of Aβ; however, no cognitive improvement in AD patients has been reported...
