| Mechanism Of Toxicity | Neosolaniol is a trichothecene. Unlike many other mycotoxins, trichothecenes do not require metabolic activation to exert their biological activity, instead directly reacting with cellular components. Trichothecenes are cytotoxic to most eukaryotic cells due to their powerful ability to inhibit protein synthesis. They do this by freely moving across the plasma membrane and binding specifically to ribosomes with high-affinity. Specifically, they interfere with the active site of peptidyl transferase at the 3'-end of large 28S ribosomal RNA and inhibit the initiation, elongation or termination step of protein synthesis, as well as cause polyribosomal disaggregation. Protein synthesis is an essential function in all tissues, but tissues where cells are actively and rapidly growing and dividing are very susceptible to the toxins. Additionally, binding to ribosomes is thought to activate proteins in downstream signalling events related to immune response and apoptosis, such as mitogen-activated protein kinases. This is known as ribotoxic stress response. Trichothecenes may also induce some alterations in membrane structure, leading to increased lipid peroxidation and inhibition of electron transport activity in the mitochondria. They can further induce apoptosis through generation of reactive oxygen species. Further secondary effects of trichothecenes include inhibition of RNA and DNA synthesis, and also inhibition of mitosis. |

1. Role of Peptide YY3-36 and Glucose-Dependent Insulinotropic Polypeptide in Anorexia Induction by Trichothecences T-2 Toxin, HT-2 Toxin, Diacetoxyscirpenol, and Neosolaniol
Jie Zhang, Qingqing Wang, Hui Jia, Wenda Wu, Yajie Zhang, Haibin Zhang Toxicol Sci . 2017 Sep 1;159(1):203-210. doi: 10.1093/toxsci/kfx128.
Trichothecences, secondary metabolites produced by Fusarium, are serious health risks to humans and animals worldwide. Although type A trichothecence-induced food refusal has been observed, the mechanism underlying the anorexia caused by these compounds is not fully understood. In this study, we hypothesized that anorexia induced by type A trichothecenes, including T-2 toxin (T-2), HT-2 toxin (HT-2), diacetoxyscirpenol (DAS), and neosolaniol (NEO), in mice corresponds to the changes in the gut satiety hormones peptide YY3-36 (PYY3-36) and glucose-dependent insulinotropic polypeptide (GIP) in plasma. A well-characterized mouse food refusal model was used in this assay. Oral exposure to or intraperitoneal (ip) injection of 1 mg/kg bw T-2, HT-2, DAS, or NEO resulted in dramatically decreased food intake, and PYY3-36 and GIP concentrations were elevated accordingly. Specifically, the PYY3-36 and GIP concentrations peaked at 2 h following oral exposure to these 4 toxins individually, although the durations were not identical. After ip administration of T-2 or HT-2, PYY3-36 significantly increased within 6 h. However, no significant difference was found in the DAS and NEO groups. The GIP levels peaked within 2, 2, 0.5, and 0.5 h, respectively, and remained increased up to 6, 6, 2, and 6 h, respectively, following T-2, HT-2, DAS, or NEO ip exposure. The increase in GIP was greater than that of PYY3-36 after exposure to the 4 toxins using 2 administration routes. Together, these findings suggest that PYY3-36 and GIP play a role in T-2-, HT-2-, DAS-, and NEO-induced anorexia.
2. Comparison of Anorectic Potencies of Type A Trichothecenes T-2 Toxin, HT-2 Toxin, Diacetoxyscirpenol, and Neosolaniol

Trichothecene mycotoxins are common contaminants in cereal grains and negatively impact human and animal health. Although anorexia is a common hallmark of type B trichothecenes-induced toxicity, less is known about the anorectic potencies of type A trichothecenes. The purpose of this study was to compare the anorectic potencies of four type A trichothecenes (T-2 toxin (T-2), HT-2 toxin (HT-2), diacetoxyscirpenol (DAS), and neosolaniol (NEO)) in mice. Following oral exposure to T-2, HT-2, DAS, and NEO, the no observed adverse effect levels (NOAELs) and lowest observed adverse effect levels (LOAELs) were 0.01, 0.01, 0.1, and 0.01 mg/kg body weight (BW), and 0.1, 0.1, 0.5, and 0.1 mg/kg BW, respectively. Following intraperitoneal (IP) exposure to T-2, HT-2, DAS, and NEO, the NOAELs were 0.01 mg/kg BW, except for DAS (less than 0.01 mg/kg BW), and the LOAELs were 0.1, 0.1, 0.01, and 0.1 mg/kg BW, respectively. Taken together, the results suggest that (1) type A trichothecenes could dose-dependently elicit anorectic responses following both oral gavage and IP exposure in mice; (2) the anorectic responses follow an approximate rank order of T-2 = HT-2 = NEO > DAS for oral exposure, and DAS > T-2 = HT-2 = NEO for IP administration; (3) IP exposure to T-2, HT-2, DAS, and NEO evoked stronger anorectic effects than oral exposure. From a public health perspective, comparative anorectic potency data should be useful for establishing toxic equivalency factors for type A trichothecenes.
3. Gut satiety hormones cholecystokinin and glucagon-like Peptide-17-36 amide mediate anorexia induction by trichothecenes T-2 toxin, HT-2 toxin, diacetoxyscirpenol and neosolaniol
Jie Zhang, Wenda Wu, Yuanyuan Li, Haibin Zhang, Shengli Liu, Hua Zhang Toxicol Appl Pharmacol . 2017 Nov 15;335:49-55. doi: 10.1016/j.taap.2017.09.020.
The food-borne trichothecene mycotoxins have been documented to cause human and animal food poisoning. Anorexia is a hallmark of the trichothecene mycotoxins-induced adverse effects. Type B trichothecenes have been previously demonstrated to elicit robust anorectic responses, and this response has been directly linked to secretion of the gut satiety hormones cholecystokinin (CCK) and glucagon-like peptide-17-36amide (GLP-1). However, less is known about the anorectic effects and underlying mechanisms of the type A trichothecenes, including T-2 toxin (T-2), HT-2 toxin (HT-2), diacetoxyscirpenol (DAS), neosolaniol (NEO). The purpose of this study was to relate type A trichothecenes T-2, HT-2, DAS and NEO-induced anorectic response to changes plasma concentrations of CCK and GLP-1. Following both oral gavage and intraperitoneal (IP) administration of 1mg/kg bw T-2, HT-2, DAS and NEO evoked robust anorectic response and secretion of CCK and GLP-1. Elevations of plasma CCK markedly corresponded to anorexia induction by T-2, HT-2, DAS and NEO. Following oral exposure, plasma CCK was peaked at 6h, 6h, 2h, 2h and lasted up to 24h, 24h, > 6h, > 6h for T-2, HT-2, DAS and NEO, respectively. IP exposed to four toxins all induced elevation of CCK with peak point and duration at 6h and >24h, respectively. In contrast to CCK, GLP-1 was moderately elevated by these toxins. Following both oral and IP exposure, T-2 and HT-2 evoked plasma GLP-1 elevation with peak point and duration at 2h and 6h, respectively. Plasma GLP-1 was peaked at 2h and still increased at 6h for IP and oral administration with DAS and NEO, respectively. In conclusion, CCK plays a contributory role in anorexia induction but GLP-1 might play a lesser role in this response.
