Amelioration of anxiety, depression, and chemotherapy related toxicity after crocin administration during chemotherapy of breast cancer: A double blind, randomized clinical trial.
The effects of saffron (Crocus sativus L.) on mood disorders have already been established. More recently, its anti-neoplastic effects have provoked a great attention. This study aims to assess the effects of crocin administration during doxorubicin-based chemotherapy of breast cancer on anxiety, depression, and chemotherapy toxicity profile. Seventy-two patients with non-metastatic Her2/neu positive or triple negative breast cancer were enrolled and randomly assigned to receive either 30 mg/day of crocin or placebo during chemotherapy [2:2]. Beck's Depression and Anxiety Inventories were used at baseline and end of the trial. In addition, the ECOG Common Toxicity Criteria were applied to assess chemotherapy side-effects. After the intervention, the degree of anxiety and depression decreased significantly in the crocin group (p = .001 for both) and increased significantly in the placebo-group (p = .006 and p = .036, respectively). There were significantly higher grade II-IV leukopenia (47.2% vs. 19.4%, p = .012) in the crocin group, and grade II-IV hypersensitivity-reaction (30.6% vs. 5.6%, p = .006) in addition to neurological disorders (66.7% vs. 41.7%, p = .03) in the placebo-group. The results indicate that using crocin during chemotherapy in patients with breast cancer has ameliorated anxiety and depression. Moreover, leucopenia increased whereas hypersensitivity reaction and neurological disorders decreased in the crocin group. In addition, a trend toward survival improvement was observed, which is going to be investigated on longer follow up.

Crocin suppresses breast cancer cell proliferation by down-regulating tumor promoter miR-122-5p and up-regulating tumor suppressors FOXP2 and SPRY2.
Crocin has been reported to have antitumor activity in several tumors including breast cancer. Nevertheless, the mechanism of action of crocin on breast cancer remains unclear. The cytotoxicity of crocin was evaluated by CCK-8 assay. Cell proliferation was assessed using EdU incorporation assay and western blot analysis. Breast cancer-related genes were extracted from GEPIA. miR-122-5p targets were predicted using Targetscan, starbase, and miRDB softwares. Luciferase reporter assay was employed to confirm whether miR-122-5p targeted sprouty2 (SPRY2) and forkhead box P2 (FOXP2). Results showed that crocin exhibited cytotoxicity and suppressed the proliferation in breast cancer cells. miR-122-5p was upregulated in breast cancer tissues and cells. Crocin suppressed miR-122-5p to block the proliferation of breast cancer cells. Seven targets of miR-122-5p were identified in breast cancer. SPRY2 and FOXP2 were selected for further experiments due to their involvement in breast cancer. miR-122-5p targeted SPRY2 and FOXP2 to inhibit their expression. miR-122-5p knockdown restrained breast cancer cell proliferation by targeting SPRY2 and FOXP2. Additionally, crocin increased SPRY2 and FOXP2 expression by inhibiting miR-122-5p expression. Together, our results suggested that crocin inhibited proliferation of breast cancer cells through decreasing miR-122-5p expression and the subsequent increase of SPRY2 and FOXP2 expression.

Crocin attenuates NF-κB-mediated inflammation and proliferation in breast cancer cells by down-regulating PRKCQ.
Breast cancer (BC) is the most commonly diagnosed cancer confronting women worldwide. Crocin, a glycosylated carotenoid extracted from Crocus sativus L., possesses anti-cancer and anti-inflammatory activities. This study tried to explore the influences of crocin on proliferation and inflammation of BC cells, and to investigate the possible mechanism. The protein levels of protein kinase C theta (PRKCQ) and nuclear factor kappa B (NF-κB) p-p65 and p65 were examined using western blot analysis. The potential targets of crocin were predicted using the PharmMapper database. Cell viability and proliferation were determined utilizing CCK-8 and EdU incorporation assays, respectively. Inflammation was assessed by detecting the levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) using RT-qPCR and ELISA. Results showed that crocin inhibited NF-κB activation and suppressed cell viability and proliferation in BC cells. Crocin caused a significant reduction of levels of TNF-α and IL-1β, suggesting that crocin suppressed inflammation in BC cells. NF-κB inhibition decreased proliferation and inflammation in BC cells. Additionally, PRKCQ was identified as a potential target of crocin according to PharmMapper database. Crocin treatment inhibited the activation of NF-κB in BC cells by reducing PRKCQ expression. Mechanistically, PRKCQ-dependent activation of NF-κB pathway reversed the effects of crocin on the proliferation and inflammation in BC cells. In conclusion, crocin inhibited NF-κB-mediated inflammation and proliferation in BC cells through reducing PRKCQ expression.

Crocin and Metformin suppress metastatic breast cancer progression via VEGF and MMP9 downregulations: in vitro and in vivo studies.
Metastatic breast cancer remains a serious health concern and numerous investigations recommended medicinal plants as a complementary therapy. Crocin is one of the known anticancer bio-component. Recently, the inhibitory effect of metformin has been studied on the various aspects of cancer. However, no study reported their combination effects on metastatic breast cancer. In the present study, we have assessed their anti-metastatic effects on in vitro and in vivo breast cancer models. Using MTT assay, scratch, and adhesion tests, we have evaluated the cytotoxic, anti-invasive and anti-adhesion effects of crocin and metformin on 4T1 cell line, respectively. Their protective effects and MMP9 as well as VEGF protein expression levels (Western blotting) investigated in the 4T1 murine breast cancer model. Our results showed that both crocin and metformin reduced cell viability, delayed scratch healing and inhibited the cell adhesion, in vitro. While crocin alone restored the mice's weight reduction, crocin, metformin, and their combination significantly reduced the tumor volume size and enhanced animal survival rate in murine breast cancer model, responses that were associated with VEGF and MMP9 down-regulation. These findings suggest that a combination of crocin and metformin could serve as a novel therapeutic approach to enhance the effectiveness of metastatic breast cancer therapy.

A Comparative Study on Anti-Invasion, Antimigration, and Antiadhesion Effects of the Bioactive Carotenoids of Saffron on 4T1 Breast Cancer Cells Through Their Effects on Wnt/β-Catenin Pathway Genes.
Crocus sativus L. (saffron) has been used as a spice and as a medicine for the past four thousand years. Recently, saffron has been well documented to possess anticancer effects on primary tumors. However studies of its antimetastatic potential are lacking. The present study is a comparative investigation of the antimetastatic effects of saffron carotenoids, crocin and crocetin, on triple negative metastatic breast cancer cells (4T1) and their effects on the Wnt/β-catenin pathway. It was found that treatment of 4T1 cells with crocin and crocetin resulted in the inhibition of viability in a dose-dependent manner. Scratch and Transwell chamber assays showed that the nontoxic doses of crocin and crocetin significantly inhibited migration, cell mobility, and invasion, also attenuating adhesion to extracellular matrix. Crocin downregulated mRNA expression of FZD7, NEDD9, VIM, and VEGF-α genes and upregulated E-CAD. Crocin and crocetin exhibited comparable anti-invasion properties on 4T1 cells. However, crocin and crocetin exerted more pronounced antimigration and antiadhesion potency, respectively. Furthermore, we showed that the antimetastatic effects of crocin can occur through interfering with the Wnt/β-catenin pathway.

Antiproliferative Activity of Crocin Involves Targeting of Microtubules in Breast Cancer Cells.
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. Electron microscopic analysis showed that crocin inhibited microtubule assembly while it induced aggregation of tubulin at higher concentrations. Crocin co-eluted with tubulin suggesting that it binds to tubulin. Vinblastine inhibited the binding of crocin to tubulin while podophyllotoxin did not inhibit the crocin binding indicating that crocin binds at the vinblastine site on tubulin. The results suggested that crocin inhibited cell proliferation mainly by disrupting the microtubule network.

Antiproliferative and Proapoptotic Effects of Crocin Combined with Hyperthermia on Human Breast Cancer Cells.
We investigated the suppressive effects of crocin alone and in combination with hyperthermia (HT) on proliferation of breast cancer cells. Cell viability, colony formation ability, and apoptosis were assessed by 3-(4,5-dimetylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT), soft agar, Hoechst 33258 staining, and percentage of lactate dehydrogenase (LDH) release methods, respectively. The mRNA levels Hsp27, Hsp70, Hsp90, Bax, and Bcl-2 were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Hsp70 and Hsp90 proteins were determined using enzyme-linked immunosorbent assay (ELISA) technique. Crocin in combination with HT significantly inhibited the proliferation of cancer cells in a dose- and time-dependent manner. There was a degree of synergism in the combined treatment. However, crocin did not show the high cytotoxic effect on normal cells. This treatment decreased colony formation of cancer cells up to 94%. Changed nuclear morphology and increased LDH indicated that crocin combined with HT has a more apoptotic effect than crocin alone. Furthermore, in treated cells Bax/Bcl-2 ratio markedly increased, whereas expression of heat-induced genes decreased. Also, the Hsp70 and Hsp90 proteins decreased in the treated cells. Our study indicated that combination of crocin and HT has strong antiproliferative and apoptotic activities against breast cancer cells. Hence, it is suggested that more studies are warranted to apply crocin as a possible, safe, and promising anticancer agent in cancer.

Effect of Crocin on Cell Cycle Regulators in N-Nitroso-N-Methylurea-Induced Breast Cancer in Rats.
We previously showed the anticancer effect of crocin, a saffron carotenoid, in both breast and gastric cancers in animal models, but its mechanism of action is not clearly known, yet. In this study, the effect of crocin on cell cycle regulators is investigated. Female Wistar Albino rats were divided into two groups, with or without N-nitroso-N-methylurea (NMU) injection. After tumor formation, each group of rats was divided into two subgroups, receiving crocin or vehicle only. After 5 weeks, the rats were sacrificed and the tumors were retained for pathologic investigation and determination of the parameters. Before crocin treatment, the tumor volumes were 13.27±3.77 and 12.37±1.88, but at the end of the experiment, they were 23.66±8.82 and 11.91±2.27 in the control and crocin-treated groups, respectively. Pathologic investigation indicated the adenocarcinoma induction by NMU. Reverse transcription-polymerase chain reaction and Western blot analysis showed overexpression of cyclin D1 and p21(Cip1) in the NMU-induced breast tumors; however, the expression of both of them suppressed by crocin treatment. The previous studies indicated that crocin induces apoptosis in tumor tissue. In this study, we show that it also suppresses tumor growth and induces cell cycle arrest by downregulation of cyclin D1. In addition, crocin suppressed p21(Cip1) in a p53-dependent manner.
