METHODS
Protein tyrosine phosphatase 1B (PTP1B) negatively regulates insulin signaling by tyrosine dephosphorylation of insulin receptor, and its increased activity and expression is implicated in the pathogenesis of insulin resistance. Hence, PTP1B inhibition is anticipated to improve insulin
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
OBJECTIVE
To investigate the clinical features and mutations of the FAH gene.
METHODS
Clinical records of two cases were collected, and diagnosis was made according to the diagnostic criteria of the International Organization for Rare Disorders (NORD). Genomic DNA was extracted from peripheral blood
Crocin, a main constituent of Crocus sativus L (saffron), has been found to inhibit the growth of K-562 human chronic myelogenous leukemia (CML) cells expressing Bcr-Abl protein tyrosine kinase activity. The aim of our study is to investigate the ability of the bioactive saffron's constituents,
The complexity of Parkinson's disease (PD) pathogenesis is attributed to multiple pathways involved in the neurodegeneration process. Among these pathways arise the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt), and mammalian target of rapamycin (mTOR) axis, where inhibition of this
A common flavonol, kaempferol, isolated from the fresh flower petals of Crocus sativus L. (Iridaceae) was found to inhibit the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) catalyzed by mushroom tyrosinase with an ID(50) of 67 microgram/mL (0.23 mM). Interestingly, its 3-O-glycoside derivatives
Signal transducer and activator of transcription 3 (STAT3) is involved in the survival, proliferation, angiogenesis, invasion and metastasis of tumor cells. In addition, interleukin-6 (IL-6) has been reported to be closely related to STAT3 activity. In the present study, we investigated whether
Parkinson's disease is caused by damage to substantia nigra dopaminergic neurons. Factors such as oxidative stress, inflammatory factors, and acetylcholinesterase activity may induce this disease. On the other hand, crocin-one of the active ingredients of saffron-has anti-oxidant and
OBJECTIVE
Gastric cancer is the first and second leading cause of cancer related death in Iranian men and women, respectively. Gastric cancer management is based on the surgery, radiotherapy and chemotherapy. In the present study, for the first time, the beneficial effect of saffron (Crocus sativus
Lead (Pb) is a metal element released into the atmosphere and a major source of environmental contamination. The accumulation and concentration of this metal in a food web may lead to the intoxication of the body, more precisely, the nervous system (NS). In addition, Pb-exposure can cause structural
BACKGROUND
There is growing evidence that the spice saffron, which contains powerful anti-oxidants, offers protection against neurodegenerative disorders, including age-related macular degeneration and Alzheimer's disease.
OBJECTIVE
We examined whether saffron pre-treatment protects dopaminergic
Culinary herbs and spices are widely used as a traditional medicine in the treatment of diabetes and its complications, and there are several scientific studies in the literature supporting the use of these medicinal plants. However, there is often a lack of knowledge on the bioactive compounds of
