Mol Cancer 2017; 16:128. [PMID: 28724435 PMCID: PMC5518133 DOI: 10.1186/s12943-017-0693-9] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2016] [Accepted: 07/10/2017] [Indexed: 01/27/2023] Open
Abstract
The WW domain is composed of 38 to 40 semi-conserved amino acids shared with structural, regulatory, and signaling proteins. WW domain-binding protein 2 (WBP2), as a binding partner of WW domain protein, interacts with several WW-domain-containing proteins, such as Yes kinase-associated protein (Yap), paired box gene 8 (Pax8), WW-domain-containing transcription regulator protein 1 (TAZ), and WW-domain-containing oxidoreductase (WWOX) through its PPxY motifs within C-terminal region, and further triggers the downstream signaling pathway in vitro and in vivo. Studies have confirmed that phosphorylated form of WBP2 can move into nuclei and activate the transcription of estrogen receptor (ER) and progesterone receptor (PR), whose expression were the indicators of breast cancer development, indicating that WBP2 may participate in the progression of breast cancer. Both overexpression of WBP2 and activation of tyrosine phosphorylation upregulate the signal cascades in the cross-regulation of the Wnt and ER signaling pathways in breast cancer. Following the binding of WBP2 to the WW domain region of TAZ which can accelerate migration, invasion and is required for the transformed phenotypes of breast cancer cells, the transformation of epithelial to mesenchymal of MCF10A is activated, suggesting that WBP2 is a key player in regulating cell migration. When WBP2 binds with WWOX, a tumor suppressor, ER transactivation and tumor growth can be suppressed. Thus, WBP2 may serve as a molecular on/off switch that controls the crosstalk between E2, WWOX, Wnt, TAZ, and other oncogenic signaling pathways. This review interprets the relationship between WBP2 and breast cancer, and provides comprehensive views about the function of WBP2 in the regulation of the pathogenesis of breast cancer and endocrine therapy in breast cancer treatment.

Exposure to zearalenone mycotoxin alters in vitro porcine intestinal epithelial cells by differential gene expression. Toxicol Lett 2014; 232:310-25. [PMID: 25455459 DOI: 10.1016/j.toxlet.2014.10.022] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2014] [Revised: 10/10/2014] [Accepted: 10/13/2014] [Indexed: 12/21/2022]
Abstract
The gut represents the main route of intoxication with mycotoxins. To evaluate the effect and the underlying molecular changes that occurred when the intestine is exposed to zearalenone, a Fusarium sp mycotoxin, porcine epithelial cells (IPEC-1) were treated with 10μM of ZEA for 24h and analysed by microarray using Gene Spring GX v.11.5. Our results showed that 10μM of ZEA did not affect cell viability, but can increase the expression of toll like receptors (TLR1-10) and of certain cytokines involved in inflammation (TNF-α, IL-1β, IL-6, IL-8, MCP-1, IL-12p40, CCL20) or responsible for the recruitment of immune cells (IL-10, IL-18). Microarray results identified 190 genes significantly and differentially expressed, of which 70% were up-regulated. ZEA determined the over expression of ITGB5 gene, essential against the attachment and adhesion of ETEC to porcine jejunal cells and of TFF2 implicated in mucosal protection. An up-regulation of glutathione peroxidase enzymes (GPx6, GPx2, GPx1) was also observed. Upon ZEA challenge, genes like GTF3C4 responsible for the recruitment of polymerase III and initiation of tRNA transcription in eukaryotes and STAT5B were significantly higher induced. The up-regulation of CD97 gene and the down-regulation of tumour suppressor genes (DKK-1, PCDH11X and TC531386) demonstrates the carcinogenic potential of ZEA.

Abstract
Fumonisin B(1) (FB(1)) is a mycotoxin produced by the fungus Fusarium verticillioides, which commonly infects corn and other agricultural products. Fusarium species can also be found in moisture-damaged buildings, and, therefore, exposure of humans to Fusarium mycotoxins including FB(1) may take place. FB(1) bears a clear structural similarity to the cellular sphingolipids, and this similarity has been shown to disturb the metabolism of sphingolipids by inhibiting the enzyme ceramide synthase leading to accumulation of sphinganine in cells and tissues. FB(1) is neurotoxic, hepatotoxic, and nephrotoxic in animals, and it has been classified as a possible carcinogen to humans. The cellular mechanisms behind FB(1)-induced toxicity include the induction of oxidative stress, apoptosis, and cytotoxicity, as well as alterations in cytokine expression. The effects of FB(1) on different parameters vary markedly depending on what types of cells are studied or what species they originate from. These aspects are important to consider when evaluating the toxic potential of FB(1).

Abstract
Fumonisin B(1) (FB(1)), a mycotoxin produced by Fusarium verticillioides present on corn and corn-based products, causes species- and organ-specific diseases. The hepatotoxic effects of FB(1) in mice have been closely correlated with the accumulation of free sphinganine, a marker for ceramide synthase inhibition, and reduced biosynthesis of more complex sphingolipids. It has been shown that FB(1) modulates expression of many cell signaling factors. In the current study we used myriocin, a specific inhibitor of serine palmitoyltransferase, to investigate the role of free sphinganine accumulation in FB(1)-induced hepatotoxicity and increased expression of selected signaling genes in BALB/c mice. The mice were pretreated daily with intraperitoneal injection of 1.0 mg/kg myriocin 30 min before subcutaneous injections of 2.25 mg/kg of FB(1) for 3 days. Results showed that myriocin alone was not hepatotoxic and the combination of myriocin plus FB(1) completely prevented the FB(1)-induced elevation of hepatic free sphinganine and prevented the FB(1)-induced induction of selected cell signaling genes, suggesting that accumulation of free sphinganine and/or its metabolites contribute to the FB(1)-modulation of the cell signaling factors. However, the combination of myriocin and FB(1) did not prevent FB(1)-increased concentration of plasma alanine aminotransferase and only slightly attenuated aspartate aminotransferase; it did not affect the FB(1)-induced hepatocyte apoptosis or increased cell proliferation. A longer combined treatment of myriocin and FB(1) was highly toxic. The hepatotoxic effects in mice seen in this study are most likely due to a combination of factors including accumulation of free sphinganine, depletion of more complex sphingolipids and sphingomyelin, or other unknown mechanisms.

Abstract
Fumonisin B(1) (FB(1)), a carcinogenic mycotoxin produced primarily by fungus Fusarium verticillioides in corn, causes several fatal animal diseases. In mice, liver is the primary site of its toxicity. Our previous study showed that maximum induction of interferon gamma (IFNgamma) and tumor necrosis factor alpha (TNFalpha) was observed at 4 and 8 h, respectively, after an acute po FB(1) treatment. To further investigate the time-related induction of other cytokines and genes involved in apoptosis signaling, male BALB/c mice were administered orally with either saline or 25 mg/kg of FB(1) and sampled 4 or 8 h after treatment. Expression of various genes was analyzed by ribonuclease protection assay. FB(1) treatment caused increased expression of TNFalpha and interleukin (IL)-1beta in both liver and kidney, whereas IL-1alpha and IL-1 receptor antagonist (IL-1Ra) expression was induced only in the liver. Expression of TNFalpha signaling molecules, TNF receptor 55 and receptor interacting protein, was increased in liver and kidney after FB(1) treatment. Caspase 8 expression was increased only in liver with no changes in kidney with FB(1). FB(1) treatment induced expression of Fas in liver and kidney with no alterations in Fas signaling molecules, Fas ligand, Fas-associated death domain and Fas-associated protein factor. Treatment of mice with FB(1) increased the expression of B-Myc, c-Myc and Max, oncogenic transcription factors in the kidney. FB(1) toxicity caused induction of cytokine network in liver with involvement of TNFalpha signaling pathway. Increased expression of caspase 8 involved in the TNFalpha signaling pathway may contribute to the apoptosis, whereas IL-1Ra induction could contribute to the proliferating effects observed in FB(1) toxicity.

Abstract
Fumonisin B1 (FB1) is a naturally occurring mycotoxin produced primarily by Fusarium verticillioides and related fungi, common contaminants of corn throughout the world. FB1 is a carcinogen and causative agent of several lethal animal diseases, including equine leukoencephalomalacia and porcine pulmonary edema. Liver is the primary target organ in mice. In vivo and vitro, cells exposed to FB1 undergo a mixture of necrotic and apoptotic cell death. Our previous studies showed gender differences in hepatotoxicity caused after 5 day FB1 treatment. Gene alterations in cytokine network and apoptosis signaling molecules were also observed after an acute single dose of FB1. To further investigate the gene alterations after a subchronic FB1 exposure and its correlation to observed gender differences, male and female BALB/c mice (five per group) were injected subcutaneously with either saline or 2.25 mg/kg per day of FB1 for 5 days. FB1 caused increased expression of tumor necrosis factor alpha (TNFalpha), interleukin (IL)-1alpha, IL-1beta, IL-1 receptor antagonist (IL-1Ra), IL-6, IL-10, IL-12 p40, IL-18 and interferon gamma (IFNgamma) in male liver, with a similar increase in females except for IL-1beta and IL-18. Control females showed higher basal levels of IL-1alpha, IL-1Ra, IL-10, IL-12 p40 and IFNgamma compared with males. Expression of TNF receptor 55 and TNF receptor associated death domain (TRADD) was increased, with no changes in Fas signaling molecules, Fas, Fas ligand (FasL), Fas associated death domain (FADD) and Fas-associated protein factor (FAF). Expression of oncogenic transcription factors, c-Myc, B-Myc, Max and Mad, and apoptotic genes, namely Bcl-2, Bax and Bad, was increased after FB1 treatment. FB1 caused an activation of cytokine network in liver, particularly the TNFalpha signaling pathway, suggesting its involvement in hepatotoxic mechanisms. Induction of IL-1Ra and oncogenes is a likely mechanism for the cancer promoting properties of FB1, through a mechanism involving apoptotic necrosis, oncotic necrosis and consequent regeneration.

Abstract
Fumonisin B(1) (FB(1)), a toxic metabolite of Fusarium verticillioides, is a carcinogen and causative agent of various animal diseases. Our previous studies indicated the involvement of tumor necrosis factor-alpha (TNF alpha) in FB(1)-induced toxic responses. To further investigate the time-course of TNF alpha production and signaling, mice (four/group) were treated subcutaneously (s.c.) or per os (p.o.) with either vehicle or 25 mg/kg of FB(1) as a single dose and sacrificed at 0, 2, 4, 8, 12 and 24 h after treatment. The TNF alpha expression was increased in liver and kidney after both routes of FB(1) exposure without any alterations in spleen. The p.o.-route FB(1) treatment caused greater hepatotoxicity compared to the s.c. route, as depicted by increased alanine aminotransferase and aspartate aminotransferase level in plasma, observed only after p.o. FB(1) treatment. The increase in enzymes at 8 h after p.o. treatment correlated with the highest TNF alpha expression, also noted at 8 h after p.o. treatment, thus further confirming the involvement of TNF alpha in FB(1) toxicity. The interferon (IFN)-gamma expression was increased in liver at 4 h after p.o. FB(1) treatment, suggesting a possible combined role of TNF alpha and IFN gamma in their induction and hepatotoxicity.
