Quercetin and anti-fungal properties -

Quercetin QCT , a dietary flavonoid, has been demonstrated to possess the antifungal function to manage clinical C. albicans biofilms and sensitize the susceptibility of FCZ-resistant C.

albicans isolates to FCZ [ 18,19 ]. albicans isolated from VVC patients. albicans isolates. albicans reference strains SC and ATCC as well as fifteen clinical isolates from VVC patients were obtained from the Department of Gynecology, the First People's Hospital of Shangqiu and stored in yeast extract-peptone-dextrose YPD, Oxoid Ltd.

These isolates were confirmed by API®32C biochemical testing panel bioMérieux UK Ltd. Then the isolates were propagated in YPD medium for 24 h at 37°C, washed by phosphate-buffered saline PBS Sigma-Aldrich, Shanghai, China , collected by centrifugation and then resuspended in RPMI medium Sigma-Aldrich, Shanghai, China for use.

The antifungal activities of QCT and FCZ against planktonic cells were represented by minimum inhibitory concentration MIC , which was defined as the lowest drug concentration inhibiting visible growth. The combination of QCT and FCZ against biofilm cells were also performed by the checkerboard assay and represented by FICI as described above [ 22 ].

The metabolic activity was performed as described before with a few modifications [ 23 ]. After incubations with antifungal drug, the supernatant was pipetted out and each well was washed by pH 7. Subsequently, the newly-prepared XTT solution was pipetted into the pre-washed wells.

The T-K test were performed according to a previous procedure with a small modifications [ 24 ]. albicans isolates in a well bottom-flat polystyrene microtiter plate. The corresponding MICs in combination were used in the ten isolates for 48 h of incubation at 37°C.

At 8, 16, 24, 32, 40, and 48 h, the strain broth was pipetted out and spread on sabouraud dextrose agar SDA, Gibco, Invitrogen, Carlsbad, CA, USA to evaluate colony forming unit CFU for another 48 h of incubation at 37°C. The control contained fungal cells and broth medium with no drug.

The interpretations were based on the h of results as follows: the synergism was defined as an increase of no less than fold in killing for the combined agents compared with the most active agent used alone, antagonism was defined as a decrease of no less than fold in killing for the combined agents compared with the most active agent alone, and the indifference was defined as a less than fold in killing for the combined agents compared with any agents used [ 25 ].

The control included no drug. After incubations, the supernatant was discarded and the wells were washed three times by sterile PBS. The adhered cells were detected by XTT assay as described above and observed by SEM as described below.

After critical point drying, the samples were sputter coated with gold in a vacuum evaporator, and the morphologies of C. alcbians 04 were observed by a scanning electron microscope SEM, JSMF, Japan. The CSH of C. albicans 04 was surveyed by the water-hydrocarbon twophase assay followed by a previous report [ 26 ].

After 10 min g of centrifugation, the fungal cells were re-suspended with sterile PBS and adjusted OD to 1. After the mixed solution was separated into two definite phases by 3 min vortex, the OD of the aqueous phase was detected. The control was set as the OD of the aqueous phase without the octane overlay.

The flocculation procedures were followed by a previous description with minor modifications [ 27 ]. Briefly, the adjusted C.

Then the suspension was vortexed for several seconds and photographed immediately. The sediments of cells were observed by inverted microscope OLYMPUS, Tokyo, Japan after 2 min. As for the test on solid plate, the strain broth of C.

The colony shape on solid plate was photographed by a digital camera Olympus, Tokyo, Japan. Before the test on semisolid plate, GM-BCP medium 10 g peptone, 5 g glucose, 0. Finally, the plate was dissected and the transection of colony was photographed laterally.

Then the slides were placed in wells of a 6-well plate containing both the strain broth of C. The working solution of FDA , µL freshly diluted in sterile PBS was added into each pre-rinsed well of well microtiter plate with µL fungal solution.

The plate was incubated in the dark at 37 °C for 30 min on a rocking table, and observed by a fluorescent microscope Olympus IX81, Tokyo, Japan at the emission wavelength of nm. The biofilm biomass was measured by crystal violet staining. Briefly, the C.

After 10 min of dyeing, the staining solution was pipetted out gently and the loose cells were removed by sterile PBS. Finally, the OD value was recorded at the wavelength of nm by a microplate reader. The CLSM procedure were undertaken as described before with a few modifications [ 28 ].

Then the supernatant was aspirated and the wells were rinsed by sterile PBS for several times. Subsequently, the freshly-prepared FUN1 solution was added into each well for 30 min of incubation at darkness.

The images were taken by confocal laser-scanning microscope Olympus Fluoview FV , and a detailed three-dimensional image of biofilm was performed using Z-stacks depending on the height of the biofilm.

After washing by PBS, the pieces were pre-incubated with fetal calf serum FCS at 37°C for 4 h, and then transferred to a clean well microtiter plate, co-incubated with C. After incubation, the next process were divided into two steps: on one hand, the supernatant µL was aspirated into a new well microtiter plate, and the OD value was detected at the wavelength of nm; on the other hand, the pieces were fetched out by forceps, rinsed by PBS, put into glass tubes with 1 mL PBS, and vortexed rigorously to detach the biofilm completely.

The solutions containing detached biofilm cells were serially 10 × diluted and spread on SDA plate for CFU counting. The qRT-PCR were performed as previously described with several modifications [ 29 ]. The total RNA was extracted from C. albicans 04 using MagExtractor-RNA kit ToyoBo, Tokyo, Japan.

The absorption was measured at and nm to confirm the purity of RNA and to calculate the amount of RNA. Approximately 1 μg of the extracted total RNA was used to synthesize cDNA by ReverTra Ace qPCR RT Master Mix with gDNA Remover kit ToyoBo, Tokyo, Japan. The primers of ALS1 , ALS3 , HWP1 , SUN41 , UME6 , ECE1 , PDE2 , NRG1 , HSP90 and ACT1 were listed in Table 1.

The procedures of qRT-PCR was performed on ABI fluorescent quantitative PCR system Applied Biosystem including 95°C for 5 min, 40 cycles of 95°C for 15 s, 48°C for 15 s, 72°C for 45 s.

All data were normalized to housekeeping gene ACT1 reference gene. The relative target-gene expression was calculated as a fold change of 2 -ΔΔCt value as previously described [ 30 ]. The murine VVC model was established according to the previous procedures described in [ 31 ]. The animal care and use committee of the First People's Hospital of Shangqiu approved the designs and procedures of the experiment.

All mice were housed in the animal center, given standard food and water provided ad libitum at room temperature for at least a week prior to next experiments. Three days prior to inoculation, mice were injected with µl of sesame oil containing 0. Estrogen injections were administered once every other day for three times in a week.

A loopful of C. albicans 04 blastoconidia from Sabouraud-dextrose agar was added into 10 ml of YPD broth supplemented with 0.

An aliquot of 20 μL of the stationary-phase suspension, generating an inoculum size of 2 × 10 6 blastoconidia, was injected into the vaginal lumen of the estrogen-treated mice.

The normal controls were inoculated with 20 µL of sterile PBS. The infected mice underwent vaginal lavage immediately with 0. The normal control and model control were treated with PBS. At day 1 postinoculation, the vaginal lumens of mice were lavaged by PBS with repeated aspiration and agitation with a pipette tip.

The lavage fluids were combined on ice during processing, were removed to perform fungal colony counting, morphology and HE staining.

All experiments were performed triplicate in three different occasions. The data were presented as means ± standard deviation and calculated by SPSS Differences between groups were determined using analysis of variance ANOVA.

The susceptibilities of 17 C. The susceptibility test showed synergism in FCZ-resistant isolates under planktonic state, and both FCZ-sensitive and -resistant isolates under biofilm states when QCT and FCZ were combined. Due to their susceptibilities to the combination of QCT and FCZ under both planktonic and biofilm states, the 10 FCZ-resistant isolates were used in T-K test.

It could be observed that the antifungal activities of QCT and FCZ alone were weaker than that of their combination Fig. The following experiments were performed in C. albicans 04 isolate due to its strong susceptibility to the combination of QCT and FCZ.

f I: indifference. g S: synergismc. Time-Kill curves of ten clinical FCZ-resistant C. The adherence is the first step of fungal biofilm formation and the initial reversible adherence is especially important for subsequent biofilm development.

The similar conclusions could be made from the SEM results Fig. The Candida CSH and flocculation were also of essential indicators of fungal adherence. albicans 04 isolate, as the results evidently displayed that the organic phase was nearly transparent Fig.

albicans 04 by A XTT assay after 2 h and 4 h incubations and B SEM after 4 h incubation. albicans Yeast-to-hypha transition is a critical process of fungal biofilm development and an important virulence factor.

In the drug-free control, the colony of C. albicans 04 isolate was wrinkled Fig. The antimycotic activity of QCT seemed to stronger than that of FCZ as the former could be more efficient to inhibit yeast-to-hypha transition in C.

albicans 04 isolate Fig. In CLSM results, the fluorescent intensity FI was between and the FIs were even more than in several biofilm areas in the control.

The dispersion was monitored in h pre-formed biofilm in C. albicans 04 isolate after drug treatments. A pre-formed biofilm dispersion by OD value at nm and B fungal quantitation on surface by colony counting in C. It could be observed that the down-regulations of ALS1 , ALS3 , HWP1 , SUN41 , UME6 and ECE1 were of 2.

qRT-PCR analyses of the mRNA expressions of ALS1 , ALS3 , HWP1 , SUN41 , UME6 , ECE1 , PDE2 , NRG1 and HSP90 normalized to housekeeping gene ACT1 in C. albicans 04 isolate. From the images of lavage, we observed abundantly criss-cross filamentous cells in the control Fig.

QCT has been demonstrated to possess a series of functions as well as antifungal potentials [ 19,32,33,34 ]. However, QCT appeared to have strong synergism with FCZ in FCZ-resistant C. albicans isolates Table 2 and Fig. As a matter of fact, most of the flavonoids were good at inhibiting the growth of FCZ-susceptible free-living cells and bad at dealing with FCZ-resistant clinical isolates and biofilms in C.

albicans , but they usually performed satisfactorily in combination with FCZ in biofilm removal [ 18,28,35,36 ]. Combinatorial therapy has become a universal approach in the prevention and management of C.

albicans biofilms [ 37 ]. albicans biofilms represent a new type of mode of fungal survival and confer to fungal pathogen greater resistance that was even up to hundreds of folds greater than their planktonic counterparts, resulting in single use of currently available antifungal agents futile.

albicans biofilms under static state demonstrated in a previous and our studies Table 2 , and can be even higher under flow condition [ 38,39 ]. Fungal adherence was one of the most important determinants of pathogenesis.

Concerning VVC infection, the clinical C. albicans isolates from VVC patients have been shown in vitro the ability to adhere to the surfaces of both microtiter plates and intrauterine contraceptive devices [ 40,41 ].

Herein, the combination of QCT and FCZ could significantly inhibit the adherence of VVC isolate Fig. ALS1 , ALS3 and HWP1 , Fig. ALS1 and ALS3 were members of the Agglutinin-Like Sequence ALS gene family and had great impacts on biofilm formation in the early stage i.

adherence stage [ 42,43,44 ]. HWP1 was a well-characterized genes encoding an important cell surface protein in C. The cell surface hydrophobicity CSH of C. albicans was reported to be implicated in the adhesion, biofilm formation and FCZ resistance, as greater CSH mostly resulted in higher ability of adherence to surface, biofilm formation, resistance to FCZ [ 47,48 ].

Apart from cell-surface adherence, the adhesins e. Als1, Als3 and Hwp1 also conferred a property of cell-cell adhesion in C. albicans , i. flocculation [ 49 ]. It could be observed that combined use of QCT and FCZ reduced the flocculation and CSH in VVC-originated C.

albicans isolate Fig. The yeast-to-hypha transition was a well-known virulence factor to cause tissue damage and a mark of biofilm development in C. albicans [ 50 ]. In this experiment, concomitant used of QCT and FCZ evidently inhibited the yeast-to-hypha transition Fig.

Notably, it was reported that ALS1 and HWP1 were also hypha-specific genes as the expression of former mRNA was correlated well with hyphal growth and the protein product encoded by the latter was only expressed on hyphae [ 51,52,53 ].

Sun41, a putative cell wall glycosidase, is required in biofilm formation, cell wall integrity, and virulence [ 54 ], while UME6 -mediated regulation of hyphal growth and biofilm development of C.

albicans was dependent on the expression of SUN41 [ 55 ]. The expressions of ECE1 and PDE2 were closely related with hyphal growth of C. albicans dependent on cAMP-PKA signaling pathway [ 56 ].

Our results indicated that QCT in combination with FCZ could dramatically influence the expressions of hypha-, biofilm-related genes i. ALS1 , HWP1 , SUN41 , UME6 , PBS2 and PDE2 , Fig. Dispersion was also believed to be an important stage in C.

albicans biofilm development, and the dispersion process occurred throughout the whole biofilm development. Fungal dispersion resulted in an initiation of fungal recolonization and a new round of Candida biofilm formation accompanying with disseminated candidiasis [ 12 ].

Although the dispersed fungal cells had different susceptibility and metabolic pattern, a hypothesis was accepted that the cells free from the protection of biofilm matrix would be more easily to be eradicated by host immune system and antifungal agents.

We found that QCT could assist FCZ to facilitate the dispersion of biofilm cells Fig. It has been reported that NRG1 and HSP90 were negatively in charges of fungal biofilm dispersion [ 57,58 ]. From our results, the expressions of both genes were upregulated by more than two folds after exposure to QCT and FCZ Fig.

A previous study demonstrated that C. albicans could adhere the vaginal mucosa and form a complex three-dimensional architecture of a typical biofilm with abundant extracellular matrix after h of infection [ 59 ], and several key transcriptional regulators e.

NRG1 and UME6 were implicated in the immunopathogenesis of Candida vaginitis via the yeast-to-hypha switch and the associated morphogenetic response [ 60 ]. After the treatments of QCT and FCZ, the fungal loading decreased Fig.

Together with these results, it could be demonstrated that QCT could be a favorable antifungal agent and a promising synergist with FCZ in the clinical management of VVC caused by C.

Research Articles November 30 Quercetin Assists Fluconazole to Inhibit Biofilm Formations of Fluconazole-Resistant Candida Albicans in In Vitro and In Vivo Antifungal Managements of Vulvovaginal Candidiasis Subject Area: Further Areas.

Mei Gao ; Mei Gao. a Department of Gynecology, the First People's Hospital of Shangqiu, Shangqiu City, Henan Province, China. Ergosterol is a vital component of the fungal cell, but little is known about the genetics and biochemistry of the ergosterol biosynthesis pathway and only 20 genes involved in the biosynthesis of ergosterol in T.

rubrum have been sequenced [ 24 ]. Zhang et al. In addition, the ERG5 , ERG6 and ERG25 genes have been shown to be up-regulated in Candida albicans strain SCAR, which is resistant to fluconazole and amphotericin B.

The higher expression of these genes may increase the conversion of lanosterol to eburicol and methyl fecosterol.

By altering the pathway at this particular point, the cell would no longer be susceptible to the effects of fluconazole or amphotericin B. Analysis of sterol content in this strain confirmed the hypothesis that resistance to the two antifungal agents was due to the accumulation of sterol intermediates, which is consistent with the inactivation of lanosterol demethylase, and to the increased expression of several ergosterol biosynthesis genes [ 25 ].

According to Leber et al. Furthermore, ergosterol has been reported to regulate its own synthesis by negative feedback mechanisms [ 27 — 30 ]. The complete assessment of the mode of action of quercetin and trans-chalcone will require the analysis of additional genes and other assays that could demonstrate the interference of FAS inhibition with fatty acid homeostasis in T.

One possibility is supplementation of the growth medium with exogenous fatty acids in the presence of quercetin and trans-chalcone. Nevertheless, the present results indicate that these compounds can be explored for the development of new antifungal drugs.

Quercetin and trans-chalcone presented the best antifungal activity among the flavonoids tested. The results of the FAS enzymatic assay showed that quercetin is a better inhibitor of this enzyme than trans-chalcone.

However, the lower MIC of trans-chalcone when compared to quercetin suggests the involvement of another cellular target in addition to FAS. Therefore, trans-chalcone is a potential candidate for the development of new antifungal drugs against T.

rubrum since it simultaneously inhibits the synthesis of fatty acids and ergosterol, a fact reducing the risk of resistance. This property is another advantage since these two targets are specific of fungal cells.
