Zhou Q, Fang G, Pang Y, Wang X. Combination of Kaempferol and Docetaxel Induces Autophagy in Prostate Cancer Cells In Vitro and In Vivo. Int J Mol Sci 2023; 24:14519. [PMID: 37833967 PMCID: PMC10572510 DOI: 10.3390/ijms241914519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 09/18/2023] [Accepted: 09/20/2023] [Indexed: 10/15/2023] Open
Abstract
Docetaxel is a first-line chemotherapy drug used to treat advanced prostate cancer, but patients who have used it often face the challenges of drug resistance and side effects. Kaempferol is a naturally occurring flavonol; our previous studies have confirmed that it has excellent anti-prostate activity. To investigate the anti-prostate cancer effects of docetaxel in combination with kaempferol, we conducted experiments at the cellular and whole-animal level. Plate cloning assays showed that the combination of docetaxel and kaempferol had a synergistic effect in inhibiting the proliferation of prostate cancer cells. The combination of these two compounds was found to induce autophagy in prostate cancer cells via transmission electron microscopy, and changes in the expression of autophagy-related proteins via Western blot assays also confirmed the occurrence of autophagy at the molecular level. We also confirmed the anti-prostate cancer effect of docetaxel in combination with kaempferol in vivo by establishing a mouse xenograft prostate cancer model. Autophagy-related proteins were also examined in mouse tumor tissues and verified the presence of autophagy in mouse tumor tissues. The above cellular and animal data suggest that docetaxel in combination with kaempferol has significant anti-prostate cancer effects and that it works by inducing autophagy in cells.

Abstract
Wnt proteins are a class of hydrophobic secreted glycoproteins involved in diverse important biological processes, such as tissue formation and regeneration, embryonic development and innate immunity. The Wnt gene family has an early origin and is present in all deuterostomes. In the process of evolution, the phenomenon of gene expansion, contraction and adaptive evolution occurs in the Wnt gene family. In the current study, eleven Wnt genes (NdWnt1-2, NdWnt4-7, NdWnt9-11, NdWnt16, and NdWntA) belonging to different subfamilies were obtained based on the genomic and transcriptomic data of Neocaridina denticulata sinensis. Then the expression patterns of all NdWnts were analyzed in various tissues, at different developmental stages and under different stresses. The expression profiles of NdWnts at different developmental stages showed that most NdWnt genes were initially expressed at gastrula stage, and the expression of NdWnt5 and NdWnt16 throughout all developmental stages. The spatial expression of NdWnt genes presented tissue specificity. They were mainly expressed in four tissues, namely gill, intestines, ovary and eyestalk. After Vibrio parahemolyticus infection and under copper exposure, the expression levels of five NdWnts (NdWnt1, NdWnt5, NdWnt10, NdWnt16 and NdWntA) were variable. Our findings enrich the research on the Wnt gene family of N. denticulata sinensis and provide valuable insights into relationship between structure and function of Wnt genes in crustaceans.

[PMID: 36041626 DOI: 10.1016/j.fsi.2022.08.057] [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: 05/26/2022] [Revised: 08/21/2022] [Accepted: 08/22/2022] [Indexed: 06/15/2023]
Abstract
Hippo signaling pathway is a serine threonine kinase cascade that is evolutionary conserved with well-established roles in organ size control, development, tumorigenesis and immunity. As its core molecule, Yorkie also plays an important role against pathogen. In this study, we cloned and characterized a Yorkie homolog from Litopenaeus vannamei, designed as LvYKI, which has a 1650 bp open reading frame. It has the characterized domains of Yokie family, and displayed to be close to the insects and crustacean. Quantitative Real-time PCR showed that LvYKI had different regulatory mechanisms in different tissues. The transcriptional level of Lvyki was down-regulated in gill, while up-regulated in hepatopancreas post white spot syndrome virus (WSSV) infection. Moreover, the expression and phosphorylation of LvYKI was reduced upon WSSV infection, which indicated that LvYKI was involved in WSSV infection. Furthermore, RNAi was performed to evaluate the role of LvYKI in shrimp immune responses. Knocking down of Lvyki resulted in inhibition of the transcription of WSSV gene ie1 and vp28, and delayed mortality of shrimp post WSSV infection. Meanwhile, the apoptosis of hemocyte was increased as well. All results suggested that shrimp can promote apoptosis to resist WSSV infection mediated by down-regulation of LvYKI. In addition, it was found that LvYKI could interact with Lvβ-catenin, which cross-linked the Wnt and Hippo signaling pathway in innate immunity. Conclusively, our study provided clues that LvYKI plays an important role in the interaction between shrimp and virus. It will promote our understanding of the molecular mechanism in innate immunity.

Comparative Transcriptome Analysis Reveals That WSSV IE1 Protein Plays a Crucial Role in DNA Replication Control. Int J Mol Sci 2022; 23:ijms23158176.

Abstract
For DNA viruses, the immediate-early (IE) proteins are generally essential regulators that manipulate the host machinery to support viral replication. Recently, IE1, an IE protein encoded by white spot syndrome virus (WSSV), has been demonstrated to function as a transcription factor. However, the target genes of IE1 during viral infection remain poorly understood. Here, we explored the host target genes of IE1 using RNAi coupled with transcriptome sequencing analysis. A total of 429 differentially expressed genes (DEGs) were identified from penaeid shrimp, of which 284 genes were upregulated and 145 genes were downregulated after IE1 knockdown. GO and KEGG pathway enrichment analysis revealed the identified DEGs are significantly enriched in the minichromosome maintenance (MCM) complex and DNA replication, indicating that IE1 plays a critical role in DNA replication control. In addition, it was found that Penaeus vannamei MCM complex genes were remarkably upregulated after WSSV infection, while RNAi-mediated knockdown of PvMCM2 reduced the expression of viral genes and viral loads at the early infection stage. Finally, we demonstrated that overexpression of IE1 promoted the expression of MCM complex genes as well as cellular DNA synthesis in insect High-Five cells. Collectively, our current data suggest that the WSSV IE1 protein is a viral effector that modulates the host DNA replication machinery for viral replication.

Abstract
White spot syndrome virus (WSSV) is a large enveloped double-stranded DNA virus that is a major impediment for shrimp aquaculture worldwide. So far, the mechanisms of WSSV-host interactions are ill-defined. Recent studies have revealed that IE1, an immediate-early protein encoded by WSSV, is a multifunctional modulator implicated in virus-host interactions. In this study, the biological functions of IE1 were further explored by identifying its interacting proteins using GST-pull down and mass spectrometry analysis. A total of 361 host proteins that potentially bind to IE1 were identified. Bioinformatics analysis revealed that the identified IE1-interacting proteins were key molecules involved in various signaling pathways such as prophenoloxidase (proPO) system, PI3K-AKT, MAPK, Focal adhesion, and cell cycle. Among these, the regulatory role of IE1 in the shrimp proPO system was further studied. The Co-immunoprecipitation (Co-IP) results confirmed that IE1 interacted with the Ig-like domain of Penaeus vannamei proPO or proPO-like proteins (proPO1/2 and hemocyanin). In addition, we found that in vivo RNAi mediated knockdown of IE1 reduced the viral genes expression and viral loads, as well as caused an increase in the PO activity of hemocytes during infection, whereas recombinant IE1 protein could inhibit the PO activity in a dose-dependent manner. Finally, our result demonstrated that WSSV could suppress the PO activity of hemocytes at the early infection stage. Collectively, our current data indicate that IE1 is a novel viral regulator that negatively modulates the shrimp proPO system, which provide additional insights into the biological functions of IE1 during WSSV infection.

FISH & SHELLFISH IMMUNOLOGY 2021; 118:228-240.

Abstract
β-catenin is a structural protein that makes the cell-cell connection in adherence junctions. Besides the structural functions, it also plays a role as a central transducer of the canonical Wnt signaling cascade, regulating nearly four hundred genes related to various cellular processes. Recently the immune functions of β-catenin during pathogenic invasion have gained more attention. In the present study, we elucidated the immune function of fish β-catenin by identifying and characterizing the β-catenin homolog (PhCatβ) from redlip mullet, Planiliza haematocheila. The complete open reading frame of PhCatβ consists of 2352 bp, which encodes a putative β-catenin homolog (molecular weight: 85.7 kDa). Multiple sequence alignment analysis revealed that β-catenin is highly conserved in vertebrates. Phylogenetic reconstruction demonstrated the close evolutionary relationship between PhCatβ and other fish β-catenin counterparts. The tissue distribution analysis showed the highest mRNA expression of PhCatβ in heart tissues of the redlip mullet under normal physiological conditions. While in response to pathogenic stress, the PhCatβ transcription level was dramatically increased in the spleen and gill tissues. The overexpression of PhCatβ stimulated M2 polarization and cell proliferation of murine RAW 264.7 macrophage. In fish cells, the overexpression of PhCatβ resulted in a significant upregulation of antiviral gene transcription and vice versa. Moreover, the overexpression of PhCatβ could inhibit the replication of VHSV in FHM cells. Our results strongly suggest that PhCatβ plays a role in macrophage activation and antiviral immune response in redlip mullet.

Abstract
Nuclear DNA-binding TCF proteins, which act as the main downstream effectors of Wnt signaling, are essential for the regulation of cell fate and innate immunity. However, their role during viral infection in shrimp remains unknown. Herein, we demonstrated that Litopenaeus vannamei TCF (LvTcf) acts independently of Lvβ-catenin to promote interferon-like protein LvVago1 production, thus mounting the response to WSSV infection. Further, we observed that WSV083, a WSSV serine/threonine protein kinase, bound to LvTcf and phosphorylated it. Phosphorylated LvTcf was then recognized and degraded via the ubiquitin-proteasome pathway. Moreover, mass spectrometry analyses indicated that the T39 and T104 residues of LvTcf were target sites phosphorylated by WSV083. Point mutation analyses suggested that additional sites of LvTcf may undergo phosphorylation via WSV083. Taken together, the current work provides valuable insights into host immunity and viral pathogenesis. LvTcf is not only a modulator of shrimp innate immunity but is also an important target for WSSV immune evasion. Thus, the current findings will help improve disease control in shrimps.

Abstract
Shrimp aquaculture is an essential economic venture globally, but the industry faces numerous challenges, especially pathogenic infections. As invertebrates, shrimp rely mainly on their innate immune system for protection. An increasing number of studies have shown that ubiquitination plays a vital role in the innate immune response to microbial pathogens. As an important form of posttranslational modification (PTM), both hosts and pathogens have exploited ubiquitination and the ubiquitin system as an immune response strategy to outwit the other. This short review brings together recent findings on ubiquitination and how this PTM plays a critical role in immune modulation in penaeid shrimps. Key findings inferred from other species would help guide further studies on ubiquitination as an immune response strategy in shrimp-pathogen interactions.

Abstract
β-catenin, an adaptor molecule in Wnt/β-catenin signaling pathway, is associated with different physiological processes such as intestinal immune, apoptosis, and inflammation-associated response. However, the function of β-catenin is still largely unknown in Apostichopus japonicus. In the present study, we cloned and characterized β-catenin gene from A. japonicus by RNA-seq and RACE approaches. The complete sequence of Ajβ-catenin consisted of a 5' UTR of 166 bp, a 3' UTR of 501 bp and an ORF of 2433 bp encoding a protein of 810 amino acids. Ajβ-catenin has a GSK-β consensus phosphorylation site of 21 amino acids located at N-terminal region and twelve Armadillo/β-catenin-like repeat (ARM) domains from 145 to 671 aa. Spatial expression analysis revealed that Ajβ-catenin mRNA levels displayed higher abundance in intestine. For Vibrio splendidus challenged sea cucumber, Ajβ-catenin transcripts reached their peak at 6 h and remained at higher levels until 24 h post infection in comparison with that of the control group. GSK-3β inhibitor treatment could induce both Ajβ-catenin and the inflammatory factors expression. Ajβ-catenin silencing could also down-regulate inflammatory factors expression. These results collectively suggested that Ajβ-catenin was a novel molecule mediate V. splendidus-induced immune response of A. japonicus via regulating the inflammatory factors expression.

Abstract
β-catenin is a multifunctional protein that participates in a variety of physiological activities, including immune regulation, sex determination, nervous system development and, cell differentiation. However, the function of β-catenin in freshwater mussel Hyriopsis cumingii remains unclear. Herein, the gene encoding β-catenin from H. cumingii (Hc-β-catenin) was cloned and characterised. The full-length 5544 bp gene includes an open reading frame (ORF) of 2463 bp encoding a putative protein of 820 amino acids residues containing 12 armadillo (ARM) repeats. After injecting H. cumingii with Aeromonas hydrophila or lipopolysaccharides, Hc-β-catenin transcription was induced in hemocytes and gills, and the greatest responses occurred at 24 h after bacterial challenge, confirming an important role in immune responses. Quantitative real-time PCR analysis showed that Hc-β-catenin mRNA was distributed in the gill, foot, liver, kidney, mantle, adductor muscle and gonad of male and female mussels. In gonad, Hc-β-catenin expression was markedly higher in females than males. During the embryonic period, Hc-β-catenin expression was highest at 3 day. In 1-, 2- and 3-year-old mature mussels, Hc-β-catenin expression in female gonad tissue was notably higher than in males. In situ hybridisation revealed a significant hybridisation signal in female gonads, indicating that Hc-β-catenin is a pro-ovarian, anti-testis gene. Our findings demonstrate that Hc-β-catenin is important in immune regulation and sex determination in freshwater mussel.

Abstract
GSK3β, a serine/threonine protein kinase, is a crucial regulator in several signaling pathway and plays a vital role in multiple cellular processes including cell proliferation, growth, apoptosis and immune response. In this study, a GSK3β homolog from L. vannamei, designed as LvGSK3β, was characterized. Sequence analysis showed that LvGSK3β possessed a highly similarity with GSK3β from other species, which contained a catalytic domain and serine/threonine phosphorylation sites. To analyze the role of LvGSK3β in the process of white spot syndrome virus (WSSV) infection, real-time quantitative PCR and western blot assays were performed. The results showed that the transcription and expression levels of LvGSK3β were inhibited upon WSSV challenge, accompanied with down-regulated phosphorylation levels. When LvGSK3β was silenced, the transcription of WSSV gene ie1 was inhibited, and the apoptosis of hemocytes induced by WSSV was up-regulated remarkably as well. In addition, inactivation of LvGSK3β could also depress virus infection that further validated the results. Conclusively, LvGSK3β was an important protein for shrimp immunomodulation, and shrimp might promote the apoptosis to restrain WSSV infection by inhibition of LvGSK3β. The study will be helpful for understanding the molecular mechanism of host-virus interaction.

[PMID: 29689303 DOI: 10.1016/j.fsi.2018.04.039] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2018] [Revised: 04/10/2018] [Accepted: 04/18/2018] [Indexed: 06/08/2023]
Abstract
Chibby, a vital inhibitor molecule of Wnt/β-catenin signaling pathway, participates in development and stem cell differentiation through the regulation of β-catenin. Our previous studies have demonstrated that Litopenaeus vannamei β-catenin (Lv-β-catenin) was involved in WSSV infection and could inhibit virus replication by modulating the host immune system. In the study, a Chibby homolog from L. vannamei (designed as Lv-Chibby) was isolated and its role in WSSV infection was investigated. Sequence analysis suggested that Lv-Chibby was a novel homolog of Chibby family. It could transcript in all examined tissues, including hemocyte, gill, intestine, hepatopancreas, muscle and heart. Real-time quantitative PCR demonstrated that Lv-Chibby could take part in WSSV infection and be down-regulated by WSSV. Further studies confirmed that Lv-Chibby was able to interact with Lv-β-catenin. Moreover, the relationship of Lv-β-catenin, Lv-Chibby and WSSV069 was investigated. It was shown that Lv-Chibby enhanced the interaction between Lv-β-catenin and WSSV069. Interestingly, WSSV069 promoted the interaction between Lv-β-catenin and Lv-Chibby under high concentration, while low concentration of WSSV069 inhibited their interaction. A subsequent immunofluorescence assay revealed that WSSV069 appeared to reduce the nuclear entry of Lv-β-catenin. In sum, these results implied that Wnt/β-catenin signal pathway plays an important role in the defense against virus, and Chibby could be modulated by WSSV to regulate the signal pathway.
