If plants exhibit resistance or resilience to pathogens, those exposed to pathogen challenge may grow further and form new unchallenged leaves. The purpose of this study was to examine disease resistance in the newly formed leaves of plants subjected to pathogen challenge. We used Arabidopsis thaliana and the oomycete pathogen Hyaloperonospora arabidopsidis (Hpa) as the model pathosystem. We found that Arabidopsis seedlings primarily challenged with the avirulent isolate Hpa exhibited enhanced disease resistance against the virulent isolate Hpa in newly formed rosette leaves (NFRLs). Our observations indicated that the transcript levels of the transcription factor gene WRKY70, which is essential for full resistance to the virulent isolate HpaNoco2, were elevated and maintained at high levels in the NFRLs. In contrast, the transcript levels of the salicylic acid marker gene PR1 and systemic acquired resistance-related genes did not exhibit sustained elevation. The maintenance of increased transcript levels of WRKY70 operated independently of non-expressor of pathogenesis-related gene 1. These findings suggest that prolonged upregulation of WRKY70 represents a defensive state synchronized with plant development to ensure survival against subsequent infections.","PeriodicalId":12742,"journal":{"name":"Genes to Cells","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142521735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Activation of the Notch signaling pathway, a major contributor to cell-cell interactions, is a potential mechanism for cell adaptation to nutrient-poor conditions. Our previous study also demonstrated that during embryogenesis when nutrients such as glutamine and growth factors are potentially maintained at lower levels, Notch signaling suppresses mRNA expression of hexokinase 2 (hk2), which is a glycolysis-associated gene, in the central nervous system. However, whether and how the genetic regulation of HK2 via Notch signaling contributes to cellular adaptability to nutrient-poor environments remains unknown. In this study, we performed gene expression analysis using a U87-MG human glioma cell line and revealed that under conditions where both glutamine and serum were absent, Notch signaling was activated and HK2 expression was downregulated by Notch signaling. We also found that Notch-mediated HK2 suppression was triggered in a Notch ligand-selective manner. Furthermore, HK2 was shown to inhibit cell proliferation of U87-MG gliomas, which might depend on Notch signaling activity. Together, our findings suggest the involvement of Notch-mediated HK2 suppression in an adaptive mechanism of U87-MG glioma cells to nutrient-poor conditions.","PeriodicalId":12742,"journal":{"name":"Genes to Cells","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142499089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further analyze the role of Pbp1 in gene expression, we first examined the time course of gene expression after transfer from YPD medium containing glucose to YPGlyLac medium containing glycerol and lactate. At 12 h after transfer to YPGlyLac medium, the pbp1∆ mutant showed decreased expression of genes related to mitochondrial function but no decrease in expression of glycogenesis-related genes. We also examined a role of the Pbp1-binding factor, Mkt1. The mkt1∆ mutant, like the pbp1∆ mutant, showed slow growth on YPGlyLac plate and reduced expression of genes related to mitochondrial function. Furthermore, we found that mutation of DHH1 gene encoding a decapping activator exacerbated the growth of the pbp1∆ mutant on YPGlyLac plate. The dhh1∆ mutant showed reduced expression of genes related to mitochondrial function. These results indicate that Pbp1 and Mkt1 regulate the expression of genes related to mitochondrial function and that the decapping activator Dhh1 also regulates the expression of those genes.","PeriodicalId":12742,"journal":{"name":"Genes to Cells","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142499090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we evaluated the effects of the exon skipping method using kidney organoids generated from AS-patient-derived induced pluripotent stem cells (AS-iPSCs). We generated kidney organoids from AS-iPSCs, which exhibited nephron structures. As expected, the C-terminus of COL4A5 was not expressed in AS-organoids. Interestingly, anti-sense oligonucleotides restored the expression of the C-terminus of COL4A5 in vitro. Next, we transplanted AS-organoids into mice and evaluated glomerular basement membrane formation in vivo. We found that AS-organoids formed a lower slit diaphragm ratio compared to control organoids. Finally, we assessed the effects of exon skipping on transplanted organoids but observed minimum effects. These studies suggest that AS-iPSCs can generate kidney organoids lacking the C-terminus of COL4A5, and that exon skipping can induce its expression in vitro.","PeriodicalId":12742,"journal":{"name":"Genes to Cells","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142463122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The D1 mice line developed dermatitis, which was not observed in D2 mice. The expression of S100a8/S100a9 was elevated in D1 to a level higher than in D2, suggesting their roles in dermatitis development. CD8 T cells of both D1 and D2 lines expressed inhibitory receptors associated with the exhausted state. In the absence of MHC class II, the skin inflammation was exacerbated in both lines. The gene expression pattern of CD8 T cells became similar to that of effector T cells. Blocking Ab against LAG3 upregulated the expression of the effector molecules of T cells.

At an early two-cell stage after cell division, the cell doublet typically displays \"inverted\" polarity, with apical and basolateral proteins being located to the ECM-facing and cell-cell-contacting plasma membranes, respectively. Correct cystogenesis requires polarity reorientation, a process containing apical protein endocytosis from the ECM-abutting periphery and subsequent apical vesicle delivery to a cell-cell contact site for lumen formation. Here, we show that downstream of the ECM-signal-transducer β1-integrin, Rac1, and its effector IQGAP1 promote apical protein endocytosis, contributing to polarity reorientation of mammalian epithelial Madin-Darby canine kidney (MDCK) cells at a later two-cell stage in three-dimensional culture. Rac1-GTP facilitates IQGAP1 interaction with the Rac-specific activator Tiam1, which also contributes to the endocytosis and enhances the effect of IQGAP1. These findings suggest that Tiam1 and IQGAP1 form a positive feedback loop to activate Rac1. With Rac1-GTP, IQGAP1 also binds to AP2α, an adaptor protein subunit for clathrin-mediated endocytosis; depletion of the AP2 complex impairs apical protein endocytosis in MDCK doublets. Thus, Rac1 likely participates in polarity reorientation at the two-cell stage via its interaction with IQGAP1.","PeriodicalId":12742,"journal":{"name":"Genes to Cells","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142389828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surprisingly, ZEB1 overexpression increased the endogenous level of ZEB2 in MOC cells, and vice versa. The molecular mechanisms underlying these findings remain unclear. However, the in vitro anchorage-independent growth of MOC cells overexpressing ZEB2 was considerably greater than that of MOC cells overexpressing ZEB1.

The CAHS (cytosolic abundant heat-soluble) protein family has been identified as one of the anhydrobiosis-related proteins. In particular, CAHS3 protein from an anhydrobiotic tardigrade, Ramazzottius varieornatus, shows heat-solubility and reversible condensation and is one of the most highly expressed among the CAHS paralogs. A recently developed tardigrade-specific vector showed tissue-specific expression of RvCAHS3 most pronounced in the epidermis in vivo, contrary to the idea that anhydrobiotic genes are uniformly expressed in all tardigrade cells. In this study, we investigated the regulation of RvCAHS3 gene expression through in vivo expression experiments using tardigrade vectors with a series of truncated upstream regions coupled with in silico analysis to identify the anhydrobiosis-related genes that are expressed under the same regulatory system as RvCAHS3. As a result, the 300-350 bp region upstream of RvCAHS3 is critical for regulating gene expression in tardigrade vector experiments, and three motifs conserved between two species of anhydrobiotic tardigrades were identified within a 500 bp region directly upstream of RvCAHS3 start codon. These motifs, which have also been identified upstream of other CAHS genes, could be associated with the regulatory system of anhydrobiosis-related genes in tardigrades.","PeriodicalId":12742,"journal":{"name":"Genes to Cells","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142345083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
