Fusarenon X is a type B trichothecene mycotoxin typically derived from Fusarium species. It is primarily found in contaminated cereals. Fusarenon X inhibits protein synthesis, which leads to disruption of DNA synthesis. As this occurs in actively proliferating cells, fusarenon X causes immunosuppression, intestinal malabsorption, developmental toxicity, and genotoxicity. Fusarenon X can be metabolized to fusarenon X-glucoside by infected plants.

Comparison of murine anorectic responses to the 8-ketotrichothecenes 3-acetyldeoxynivalenol, 15-acetyldeoxynivalenol, Fusarenon X and nivalenol
Food Chem Toxicol 2012 Jun;50(6):2056-61.PMID:22465835DOI:10.1016/j.fct.2012.03.055.
While induction of food refusal by the trichothecene mycotoxin deoxynivalenol (DON) has been described in several animal models, much less is known about the anorectic effects of structurally related 8-ketotrichothecenes, 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), Fusarenon X (FX) and nivalenol (NIV). Here, we compared the capacities of these congeners to induce anorexia in the mouse. As previously observed for DON, anorectic responses to 3-ADON and 15-ADON in the B6C3F1 female mouse following both intraperitoneal (IP) and oral exposure were transient, lasting only a few hours, with food intake recovering to control levels within 16 h. For both ADONs, the no observed adverse effect levels (NOAEL) and lowest observed adverse effect levels (LOAEL) were 0.5 and 1mg/kg bw following IP exposure, respectively, and 1 and 2.5mg/kg bw after oral exposure, respectively. In contrast, food refusal persisted from 48 to 96 h following IP and oral exposure to FX and NIV. For both IP and oral FX exposure, the NOAEL was 0.025 mg/kg bw and LOAEL was 0.25mg/kg bw, whereas the NOAELs and LOAELs for NIV were 0.01 and 0.1mg/kg bw, respectively, after IP exposure and 0.1 and 1mg/kg bw, respectively, following oral exposure. Both these data and a prior DON study suggest that anorectic responses to 8-ketotrichothecenes were always greater when administered IP as compared to oral exposure and follow an approximate rank order of NIV>FX>DON≈3-ADON≈15-ADON for IP exposure and FX>NIV>DON≈3-ADON≈15-ADON for oral exposure. Toxic potency data such as is described here will be applicable to future comparative risk assessments for this important group of trichothecene mycotoxins.
Role of cholecystokinin in anorexia induction following oral exposure to the 8-ketotrichothecenes deoxynivalenol, 15-acetyldeoxynivalenol, 3-acetyldeoxynivalenol, Fusarenon X, and nivalenol
Toxicol Sci 2014 Apr;138(2):278-89.PMID:24385417DOI:10.1093/toxsci/kft335.
Cereal grain contamination by trichothecene mycotoxins is known to negatively impact human and animal health with adverse effects on food intake and growth being of particular concern. The head blight fungus Fusarium graminearum elaborates five closely related 8-ketotrichothecene congeners: (1) deoxynivalenol (DON), (2) 3-acetyldeoxynivalenol (3-ADON), (3) 15-acetyldeoxynivalenol (15-ADON), (4) Fusarenon X (FX), and (5) nivalenol (NIV). While anorexia induction in mice exposed intraperitoneally to DON has been linked to plasma elevation of the satiety hormones cholecystokinin (CCK) and peptide YY₃₋₃₆ (PYY₃₋₃₆), the effects of oral gavage of DON or of other 8-keotrichothecenes on release of these gut peptides have not been established. The purpose of this study was to (1) compare the anorectic responses to the aforementioned 8-ketotrichothecenes following oral gavage at a common dose (2.5 mg/kg bw) and (2) relate these effects to changes plasma CCK and PYY₃₋₃₆ concentrations. Elevation of plasma CCK markedly corresponded to anorexia induction by DON and all other 8-ketotrichothecenes tested. Furthermore, the CCK1 receptor antagonist SR 27897 and the CCK2 receptor antagonist L-365,260 dose-dependently attenuated both CCK- and DON-induced anorexia, which was consistent with this gut satiety hormone being an important mediator of 8-ketotrichothecene-induced food refusal. In contrast to CCK, PYY₃₋₃₆ was moderately elevated by oral gavage with DON and NIV but not by 3-ADON, 15-ADON, or FX. Taken together, the results suggest that CCK plays a major role in anorexia induction following oral exposure to 8-ketotrichothecenes, whereas PYY₃₋₃₆ might play a lesser, congener-dependent role in this response.
Apoptosis and gene expression in Jurkat human T cells and lymphoid tissues of fusarenon-X-treated mice
Toxicon 2016 Dec 1;123:15-24.PMID:27773736DOI:10.1016/j.toxicon.2016.10.012.
Fusarenon X, a member of the type B trichothecene mycotoxin group, has been frequently observed, along with deoxynivalenol (DON) and nivalenol (NIV) as a contaminant in cereals. Our previous study demonstrated that a 14-day FX exposure caused apoptosis in the lymphoid tissues of mice, especially at 0.5 mg/kg bodyweight. However, the relationship between low concentrations of FX and apoptotic molecular machinery remains unclear. In the present study, we investigated the genetic regulatory mechanisms in the thymus and Peyer's patches of mice after 14 days oral administration of FX at 0.5 mg/kg bodyweight. FX caused the up-regulation of Bax, Bid, Trp53, and Caspase-9 mRNA but the relative expression of Fas, TNF, and Caspase-8 remained unchanged. Furthermore, we also determined the toxicity of FX in Jurkat T-cells. FX exhibited a concentration- and time-dependent inhibition of cell viability. Thus, incubation time and FX concentration influence the percentage of apoptotic cells. These data suggested that treatment with low dosage of FX can induce apoptosis in lymphocytes through an effect on Bax, Bid, Trp53, and Caspase-9 and therefore the mitochondrial apoptotic pathway.
