They produce a plethora of biologically active secondary metabolites, including a wide variety of clinically important drugs. For example, fungi produce beta lactam antibiotics such as penicillin and cephalosporin, which have been dominating the antibiotic market until recently, and were the stepping stones for the development of next generation antibiotics 3. Furthermore, other fungal compounds such as the immunosuppressant cyclosporine and cholesterol lowering compactin and lovastatin are frequently used in the clinic 3 , 4 , 5.

Given the estimates of the biodiversity in the fungal kingdom and the notion that only a small fraction of fungi has ever been tested for the production of biologically active compounds, it is evident that a wealth of compounds is still to be discovered.

This is underlined by the identification of numerous new fungal metabolites in recent years 6 , 7 , 8 , 9 , To uncover compounds with biological activity produced by fungi, we use zebrafish as a model system. This has several advantages over other systems. To assess biological activity in higher eukaryotes, tissue culture cells are often being used.

However, this limits screens to cell type specific effects. In order to do whole animal testing, zebrafish Danio rerio embryos are a great model. Zebrafish are vertebrates with a highly conserved physiology. The embryos develop in aqueous medium and readily take up compounds from the medium. Furthermore, the embryos are transparent and develop all primary organs and tissues in a few days. This makes biological activities of compounds readily detectable as developmental defects in zebrafish embryos.

In addition, due to the high fecundity of zebrafish, large numbers of embryos can be obtained for experiments relatively easily, which makes them an excellent model for high-throughput screens 11 , To date, over 65 small-molecule screens using zebrafish have been reported with various read-outs such as embryo morphology or behavioral differences These screens have been successful in either discovering novel compounds or finding new purposes for existing drugs 14 , 15 , In the process, phenotypes caused by existing drugs may be indicative for the mode-of-action or targets of unexplored compounds.

Here, we combined mycology, embryology and chemistry in our analysis of 10, fungal species from the large collection of the Westerdijk Fungal Biodiversity Institute. We screened these fungi for production of secondary metabolites with biological activity, using zebrafish embryogenesis as read-out. The phenotypes caused by these secondary metabolites are diverse, ranging from severe pleiotropic to highly specific phenotypes.

We selected 39 fungi for further analysis from which we purified and identified 34 metabolites which induced specific developmental defects in zebrafish embryos. This group of identified metabolites consists of both known therapeutic compounds as well as relatively unexplored compounds that induced similar phenotypes as well-known therapeutic compounds. In the process, we generated a library of secondary metabolites from 10, fungi which can be tested in any bioassay.

A library of secreted secondary metabolites mixtures was generated using 10, strains of fungi as outlined in Fig. In short, lyophilized fungal strains were suspended in malt peptone and inoculated on agar plates. In case of sufficient growth, liquid medium aliquots 3. This medium showed the best results in a pilot experiment using a variety of liquid media on a selection of fungi.

After seven days, the broth was filtered to remove fungi and spores, resulting in sterile filtrates containing secondary metabolites. The fungal strains that were used to generate this library were picked from the collection of the Westerdijk Institute in an unbiased manner.

A complete list of the 10, fungi used is included in the Supplementary Table S1. Work-flow of the generation of the library of secondary metabolite mixtures from 10, strains of fungi and initial screen using zebrafish embryos as a read-out. See text for details. At developmental stages 24 hpf and 48 hpf, the zebrafish embryos were inspected for morphological developmental defects.

If 3 or more of the 5 embryos displayed similar developmental defects after repeated testing, the fungal filtrate was scored as positive. In addition, in case incubation with fungal filtrates was toxic, resulting in embryonic lethality at 24 or 48 hpf, the fungal filtrates were tested in serial dilutions until an ineffective dilution was reached.

Morphological defects were assessed by phase contrast microscopy. Embryos were visually inspected and all differences from wild type morphology were scored.

Pictures were taken of treated embryos during the screen to document developmental defects. We classified the phenotypical defects in 13 distinct categories: pigmentation, notochord, truncation, delayed development, fin, tail, heart, yolk, yolk extension, body axis extension, necrosis, death and other. These categories will be further explained below. In cases, phenotypes were assigned to more than one category. Table 1 shows how many filtrates induced a particular phenotype.

Representative examples of developmental defects induced by incubation with fungal filtrates are depicted in Fig. Fungal secondary metabolite mixtures induced distinct morphological defects in zebrafish embryos. Zebrafish embryos were incubated with fungal secondary metabolite mixtures from 6 hpf onwards. Embryos were imaged at 48 hpf. A Control not incubated with a fungal secondary metabolite mixture. B—H Examples of developmental defects caused by distinct fungal secondary metabolite mixtures.

Note the diversity in developmental defects between samples. The filtrates were lethal in the initial concentration. Further dilution of these fungal filtrates abolished the lethal defects, but did not lead to any specific developmental defect. In 79 cases we observed pigmentation defects. Most commonly, this involved less or no melanocytes compared to the untreated wild type embryo Fig.

Upon dilution of the fungal filtrate, the pigmentation gradually increased to normal. A rare but very specific phenotype is defective notochord development 14 times observed.

Characteristically, this category involved an undulating or kinked notochord and a curved tail Fig. Truncated embryos 67 times observed lack formation of a tail, although the anterior part of the embryo developed relatively normally Fig. Upon dilution of the sample, the truncation effect decreased and embryos developed a curved tail and reduced body axis extension was observed.

Another interesting category is delayed development 56 times observed. Here, embryonic development is slowed down or even stalled when embryos are incubated with fungal filtrate, causing them to resemble an earlier developmental stage Fig.

We found less or no fin formation on 50 occasions. This phenotype was often accompanied by a thin yolk extension Fig. The largest category of specific defects was heart defects times observed. This category covers all phenotypes involving the cardiac area. Typically, heart defects are accompanied by a cardiac edema, a stretched heart and malfunctioning blood circulation Fig. This phenotype is commonly seen in combination with other phenotypes, including yolk defects.

Yolk defects times observed mostly involved yolk edemas or yolk hemorrhages that mostly occurred simultaneously with cardiac defects and seldom on their own. In other cases, we observed a change of color of the yolk, caused by colored compounds in the medium or necrosis. We intentionally included a separate category for yolk extension defects. In these cases, the yolk itself appears normal, but the yolk extension is either swollen, thinner or even completely absent 65 times observed.

Again, this phenotype rarely occurred on its own and was mostly observed in combination with either fin or tail defects Fig. The second biggest specific category is tail defects times , covering all phenotypes involving the tail area, but excluding notochord defects and truncation phenotypes.

The embryo depicted in Fig. Necrosis, in either a part or the entire embryo, was observed with filtrates Fig. The final specific category was embryos with reduced body extension.

At first glance embryos in this category look relatively normal. However, when measured they appear shorter. These developmental defects are reminiscent of the characteristic defects that result from defective convergence and extension cell movements during gastrulation Fig. For instance, several fungal filtrates dissolved the chorion or induced premature hatching of the zebrafish embryos without affecting the embryonic development itself.

To identify the mycotoxins in the fungal filtrates responsible for the developmental defects, we performed activity-guided purification as outlined in Fig.

Next, the fungal filtrates were extracted, using ethyl acetate, evaporated to dryness and the residues were dissolved in DMSO. Routinely, we tested the extracts for biological activity prior to further processing. In most cases the biological activity was successfully retained in the ethyl acetate extracts. Next, active extracts were fractionated using preparative HPLC. These fractions were tested on zebrafish, firstly, in pools of 6 fractions and subsequently, individual fractions of selected active pools were tested.

Using this scheme, the individual fractions contained pure compounds in most cases, ready to be analyzed by analytical chemical methods. Typically, we determined the purity and nominal mass using LC-MS of the active compounds. We compared the data with available literature and databases 17 , 18 , resulting in identification of previously identified compounds. Schematic representation of the activity-guided purification and identification of active fractions. Fractions were tested for activity using zebrafish embryonic development as a read-out and biologically active fractions were selected and subjected to spectroscopic identification and characterization methods.

See Materials and Methods section for details. We initially selected the fungal filtrate of Fusarium proliferatum CBS To illustrate the undulating notochord phenotype, we used transgenic notail ntl -gfp fish in which the gene encoding Green Fluorescent Protein GFP is knocked into the ntl gene, generating a Ntl-Gfp fusion protein which is expressed under the control of the ntl promoter Ntl-Gfp is expressed predominantly in the notochord in this transgenic line Fig.

Incubation of transgenic ntl-gfp embryos with fraction 27 of the fungal filtrate from Fusarium proliferatum induced an undulating notochord, which was illustrated spectacularly by fluorescence microscopy Fig.

The anterior half of the notochord undulates, whereas the posterior part of the notochord is straight, comparable to the control. Identification of fusaric acid as bioactive compound from Fusarium proliferatum that induces an undulating notochord in zebrafish embryos. D—G Purification and identification of fusaric acid.

The major peak, fraction 27, contains the biologically active compound. G 1 H-NMR spectrum of fraction Fraction 27 of the bioactive filtrate from Fusarium proliferatum consisted of a single peak harboring the biological activity Fig.

Chemical analyses of this fraction resulted in identification of a compound with molecular mass of These data corresponded closely with reported data of fusaric acid Moreover, Fusarium species are well-known to produce fusaric acid 20 , and fusaric acid has been shown to induce an undulating notochord in zebrafish embryos Altogether, this suggested that the bioactive compound from Fusarium proliferatum was fusaric acid. To verify this, we tested commercially available fusaric acid in parallel with the bioactive compound we had isolated.

The phenotypes induced by the purified compound and the commercially available fusaric acid were identical Fig. Thus, we conclude that the compound produced by Fusarium proliferatum which induced an undulating notochord in zebrafish embryos was fusaric acid. Next, we focused on the shorter category. Zebrafish embryos in this category display reduced body axis extension occasionally combined with other developmental defects, including cardiac edema, craniofacial defects, pigmentation defects and yolk defects Fig.

We selected this category because embryos in this category resemble embryos we have reported before, in which key signaling molecules have been knocked down or knocked out 22 , 23 , 24 , 25 , Furthermore, embryos which have been treated with small molecule inhibitors that induce convergence and extension cell movement defects, including the PI3Kinase inhibitor, LY 27 , 28 , show a similar phenotype.

At later stages, this phenotype is combined with other defects, typically including cardiac edema, pigmentation defects and craniofacial defects. We hypothesize that fungal compounds might act in these important pathways.

The fungal filtrates from 39 species of fungi that induced a reduction in body axis extension were processed to isolate and identify the bioactive compound responsible for the observed defect.

We identified 34 known metabolites from 39 bioactive fungi Table 2 , Fig. These known metabolites include known therapeutic compounds such as the antifungal griseofulvin, immunosuppressant cyclosporine and HMG-CoA reductase inhibitors compactin also known as mevastatin and lovastatin. Furthermore, a noteworthy compound we found in our screen is bostrycin. Other identified compounds include sparsely investigated compounds such as anthracobic acid A and CJ Since not much is known about these compounds and they induced similar phenotypes as therapeutic compounds, they are interesting for further investigation.

On the other hand, one group of compounds we repeatedly found was the group of macrocyclic trichothecenes Fig. These molecules have a characteristic backbone, containing an epoxy-group at C and are reported to be highly toxic. However, in our screen we found characteristic phenotypes in nanomolar concentrations suggesting that these compounds might act on a specific pathway in low concentrations. All analytical chemical data of the identified compounds is available in the Supplementary Note.

The chemical structures of compounds that reduce body axis extension are diverse. The chemical structures of the compounds that induce shorter phenotypes are depicted here. These compounds are listed in Table 2 as well. The chemical structures of the family of macrocyclic trichothecenes, which reduce body axis extension Table 2 show that these compounds clearly belong to the same family of chemical compounds.

To confirm our results, we ordered and tested all commercially available compounds in serial dilutions and found shorter phenotypes in all of them Fig. In the process, we found additional phenotypes of several compounds in high concentrations. Therapeutic statin compounds, like mevastatin, showed pleiotropic phenotypes including curved tail, reduced pigmentation, cardiac edema and affected vasculature in high concentrations Fig.

In lower concentrations these severe effects were abolished and the reduced body axis extension phenotype became evident Fig. Likewise, the trichothecene compounds induced truncation in high concentration Fig. Again, in lower concentrations this effect is abolished and we observed the reduced body axis extension phenotype.

Finally, to assess whether embryos in the reduced body axis extension category also displayed characteristic craniofacial defects, we performed alcian blue stainings on compound treated embryos and found that indeed these treated embryos displayed craniofacial defects, including blunted face and wide-set eyes Fig.

These craniofacial defects resemble the defects in embryos lacking functional Shp2 23 , suggesting that specific signaling pathways are inhibited in response to the fungal secondary metabolites.
