Fucosyltransferase 8 regulates adult neurogenesis and cognition of mice by modulating the Itga6-PI3K/Akt signaling pathway. SCIENCE CHINA. LIFE SCIENCES 2024; 67:1427-1440. [PMID: 38523237 DOI: 10.1007/s11427-023-2510-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 11/14/2023] [Indexed: 03/26/2024]
Abstract
Fucosyltransferase 8 (Fut8) and core fucosylation play critical roles in regulating various biological processes, including immune response, signal transduction, proteasomal degradation, and energy metabolism. However, the function and underlying mechanism of Fut8 and core fucosylation in regulating adult neurogenesis remains unknown. We have shown that Fut8 and core fucosylation display dynamic features during the differentiation of adult neural stem/progenitor cells (aNSPCs) and postnatal brain development. Fut8 depletion reduces the proliferation of aNSPCs and inhibits neuronal differentiation of aNSPCs in vitro and in vivo, respectively. Additionally, Fut8 deficiency impairs learning and memory in mice. Mechanistically, Fut8 directly interacts with integrin α6 (Itga6), an upstream regulator of the PI3k-Akt signaling pathway, and catalyzes core fucosylation of Itga6. Deletion of Fut8 enhances the ubiquitination of Itga6 by promoting the binding of ubiquitin ligase Trim21 to Itga6. Low levels of Itga6 inhibit the activity of the PI3K/Akt signaling pathway. Moreover, the Akt agonist SC79 can rescue neurogenic and behavioral deficits caused by Fut8 deficiency. In summary, our study uncovers an essential function of Fut8 and core fucosylation in regulating adult neurogenesis and sheds light on the underlying mechanisms.

Exposure to pyrazosulfuron-ethyl induces immunotoxicity and behavioral abnormalities in zebrafish embryos. FISH & SHELLFISH IMMUNOLOGY 2022; 131:119-126. [PMID: 36195270 DOI: 10.1016/j.fsi.2022.09.063] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 09/18/2022] [Accepted: 09/28/2022] [Indexed: 06/16/2023]
Abstract
Pyrazosulfuron-ethyl is one of the most widely used herbicides in agriculture and can be widely detected in aquatic ecosystems. However, its biosafety, including its potential toxic effects on aquatic organisms and its mechanism, is still poorly understood. As an ideal vertebrate model, zebrafish, the effect of pyrazosulfuron-ethyl on early embryonic development and immunotoxicity of zebrafish can be well evaluated. From 10 to 72 h post fertilization (hpf), zebrafish embryos were exposed to 1, 5, and 9 mg/L pyrazosulfuron-ethyl which led in a substantial reduction in survival, total length, and heart rate, as well as a range of behavioral impairments. In zebrafish larvae, the number of neutrophils and macrophages was considerably decreased and oxidative stress levels increased in a dose-dependent way after pyrazosulfuron-ethyl exposure. And the expression of immune-related genes, such as TLR-4, MyD88 and IL-1β, were downregulated by pyrazosulfuron-ethyl exposure. Moreover, pyrazosulfuron-ethyl exposure also inhibited motor behavior. Notch signaling was upregulated after exposure to pyrazosulfuron-ethyl, while inhibition of Notch signaling pathway could rescue immunotoxicity. Therefore, our findings suggest that pyrazosulfuron-ethyl has the potential to induce immunotoxicity and neurobehavioral changes in zebrafish larvae.

Lenvatinib induces cardiac developmental toxicity in zebrafish embryos through regulation of Notch mediated-oxidative stress generation. ENVIRONMENTAL TOXICOLOGY 2022; 37:1310-1320. [PMID: 35119177 DOI: 10.1002/tox.23485] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 01/17/2022] [Accepted: 01/22/2022] [Indexed: 06/14/2023]
Abstract
Due to an increasing number of abused drugs dumped into the wastewater, more and more drugs are detected in the water environment, which may affect the survival of aquatic organisms. Lenvatinib is a multi-targeted tyrosine kinase inhibitor, and is clinically used to treat differentiated thyroid cancer, renal epithelial cell carcinoma and liver cancer. However, there are few reports on the effects of lenvatinib in embryos development. In this study, zebrafish embryos were used to evaluate the effect of lenvatinib on cardiovascular development. Well-developed zebrafish embryos were selected at 6 h post fertilization (hpf) and exposed to 0.05 mg/L, 0.1 mg/L and 0.2 mg/L lenvatinib up to 72 hpf. The processed embryos demonstrated cardiac edema, decreased heart rate, prolonged SV-BA distance, inhibited angiogenesis, and blocked blood circulation. Lenvatinib caused cardiac defects in the whole stage of cardiac development and increased the apoptosis of cardiomyocyte. Oxidative stress in the processed embryos was accumulated and inhibiting oxidative stress could rescue cardiac defects induced by lenvatinib. Additionally, we found that lenvatinib downregulated Notch signaling, and the activation of Notch signaling could rescue cardiac developmental defects and downregulate oxidative stress level induced by lenvatinib. Our results suggested that lenvatinib might induce cardiac developmental toxicity through inducing Notch mediated-oxidative stress generation, raising concerns about the harm of exposure to lenvatinib in aquatic organisms.
