Inhibitory effect of saffron, crocin, crocetin, and safranal against adipocyte differentiation in human adipose-derived stem cells.
    Journal of ethnopharmacology, 2022, Aug-10, Volume: 294

    Saffron (Crocus sativus L.) has been introduced as a potential promising natural antioxidant with anti-obesity properties. In Persian Medicine, saffron has been used to control appetite and obesity.. The present study aims to investigate the effect of saffron and its bioactive compounds on adipocyte differentiation in human adipose-derived stem cells (ADSCs).. Flow-Cytometric analysis was performed to quantify the cell surface markers. The extracts cytotoxicity on hASCs was measured using alamarBlue® assay whereas their activities against adipocyte differentiation were studied using Oil Red O staining. The level of Peroxisome proliferator-activated receptor-γ (PPARγ), Fatty Acid Synthetase (FAS), and Glyceraldehyde-3-phosphate dehydrogenase (GAPHD) which are key proteins in cell differentiation was investigated by western blot analysis.. Flow-cytometry revealed the mesenchymal stem cells markers, CD44 and CD90, on ADSCs surface. The saffron, crocin, and crocetin significantly inhibited adipocyte differentiation while saffron up to 20 μg/mL and crocin, crocetin and safranal up to 20 μM did not exhibit cytotoxicity. The western blotting analysis revealed a remarkable reduction in the level of PPARγ, GAPDH, and FAS proteins by 10 and 20 μM of crocin and 2.5 and 5 μM of crocetin.. It seems that saffron, crocin, and crocetin could efficiently inhibit the differentiation of hASCs with benefits for the treatment and prevention of obesity.

Protective effects of quercetin and crocin in the kidneys and liver of obese Sprague-Dawley rats with Type 2 diabetes: Effects of quercetin and crocin on T2DM rats.
    Human & experimental toxicology, 2021, Volume: 40, Issue:4

    Quercetin and crocin are the main active constituents of Eucommia and Gardenia species, respectively. This study was conducted to explore the effects of quercetin and crocin on fat reduction and renal fibrosis and the relationship of these compounds with autophagy. First, a model of high-fat diet- and streptozotocin-induced type 2 diabetes was established and then subjected model animals to 8 weeks of metformin, quercetin and crocin gavage. Then, a high glucose-induced rat mesangial cells (RMCs) model was established, and these cells were cocultured with quercetin and crocin. The results showed that quercetin and crocin can decrease fasting blood glucose levels, reduce fat accumulation in the liver, alleviate renal fibrosis, and reduce blood lipid levels. Quercetin and crocin increased autophagy-related protein (LC3, Atg5, Beclin-1 and p-AMPK) levels in the liver and decreased autophagy-related protein (LC3, Atg5, Beclin-1 and p-AMPK) levels in the kidneys. Moreover, quercetin and crocin inhibited the excessive proliferation of RMCs induced by high-glucose (HG) conditions, decreased autophagy-related protein (LC3, Atg5, Beclin-1 and p-AMPK) levels, and decreased TGF-β1 expression. Importantly, cotreatment with quercetin and crocin had a more significant effect than treatment with either compound alone. These results suggest that combined administration of quercetin and crocin can more significantly reduce blood glucose/lipid levels and improve renal fibrosis than administration of either compound alone and that AMPK-dependent autophagy might be involved in this process.

Crocin inhibits obesity via AMPK-dependent inhibition of adipocyte differentiation and promotion of lipolysis.
    Bioscience trends, 2018, Volume: 12, Issue:6

    Obesity has become a severe public health problem worldwide. Crocin, a natural product, has been reported to have a number of pharmacological activities, including anti-inflammatory, anti-cancer, neuroprotective, antihypertensive, and cardioprotective action. The aims of the current study were to identify the beneficial effects of crocin on obesity, adipocyte differentiation, and lipolysis and to evaluate the possible role of AMPK. Results indicated that crocin significantly increased AMPK phosphorylation in differentiated adipocytes in vitro and in adipose tissue in db/db mice. Crocin reduced lipid accumulation in differentiated adipocytes. In addition, crocin inhibited the expression of mRNA of important adipogenesis-related regulators, including CEBPα, CEBPβ, PPARγ, aP2, FAS, and CD36, in both differentiated adipocytes and adipose tissue in db/db mice. Crocin increased the expression of mRNA of key lipolysis-associated factors, including PPARα, LPL, and HSL, in both differentiated adipocytes and adipose tissue in db/db mice. In adipocytes, knockdown of AMPK significantly suppressed the crocin-induced inhibition of adipocyte differentiation and increase in lipolysis. BML-275 is an inhibitor of AMPK. In adipose tissue in db/db mice, BML-275 suppressed crocin-induced inhibition of fat formation and alleviation of a metabolic disorder. The current results suggest that crocin alleviates obesity in db/db mice and that it inhibits adipocyte differentiation in preadipocytes. Crocin inhibits adipogenesis and promotes lipolysis via activation of AMPK. Therefore, crocin may have promise as an option for the clinical treatment for obesity and associated metabolic diseases.

Effects of crocin on experimental obesity and type-2 diabetes.
    Turkish journal of medical sciences, 2016, Nov-17, Volume: 46, Issue:5

    The aim of this study is to scrutinize the effects of crocin on obesity and type-2 diabetes, with an approach that takes oxidative stress and inflammatory parameters into account.. The experimental obesity model was created by utilizing a 10-week-long high-fat diet (HFD). An experimental type-2 diabetes model was created by injecting multiple low-dose streptozocin (STZ) injections into rats that were fed with the HFD. The treatment groups were administered a daily crocin dose of 150 mg/kg for 6 weeks via gavage.. Findings of the study demonstrated that crocin could be effective in relieving the symptoms of obesity and diabetes (hyperinsulinemia, hyperleptinemia, insulin resistance, and weight gain). It was determined that crocin lowered the plasma TNF-α and IL-1β levels and the pancreas tissue TNF-α and IFN-γ levels, which were increased due to diabetes, and reduced the inflammation in diabetic rats. Similarly, it was found that oxidative stress, which increased due to the progress of diabetes, was reduced in crocin treatment group.. Crocin could contribute to the development of phytotherapeutic approaches in the treatment of obesity, diabetes, and diabesity (obesity-induced diabetes), which is promising as the abovementioned incidences have increased considerably in today's world.
