The metabolic diversity of P. kurroa may stem from the evolutionary processes attributed to pathway genes family expansion via gene duplication or splicing giving rise to paralogues which are further controlled by regulatory components. Occurrence of multiple pathway gene paralogues coupled with which TFs associate with paralogues in different genetic backgrounds (populations) in tissue-specific manner are still unresolved. Here, we unravelled possible correlations between TFs and gene paralogues across a range of P. kurroa accessions which might be contributing to differential contents of Picroside-I and Picroside-II in different tissues/organs. Characterization of shoots, roots, and stolons of eighty-five accessions of P. kurroa revealed significant variations for Picroside-I and Picroside-II contents. Comparative transcriptome analysis of shoot-derived transcriptome (PKSS), and root-derived transcriptome (PKSR) followed by their expression analysis in different P. kurroa accessions revealed TFs; PkWRKY71, PkWRKY12, PkNAC25, and PkMyb46 possibly regulate different gene paralogues. Genes encoding these putative TFs and pathway gene paralogues were further used to generate a robust co-expression network, thereby, uncovering their coordinated behaviour in association with Picroside-I and Picroside-II contents in shoots and roots, respectively. The outcome has provided potential leads, which through further functional validation can provide suitable targets, either for pathway engineering or as gene markers for selection of genetically superior populations of P. kurroa.</p>","PeriodicalId":482,"journal":{"name":"Biochemical Genetics","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142278423","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}

Against the backdrop of efferocytosis's increasingly recognized role in cancer, this research endeavors to develop and authenticate a prognostic signature intricately linked to efferocytosis in bladder cancer. LASSO-COX regression analysis crafted an efferocytosis-related genes risk prognostic model, followed by the construction of a column chart. External validation sets confirmed the predictive accuracy of both the model and chart. Clinical, tumor microenvironment, drug sensitivity, and immunotherapy analyses were employed to comprehensively assess efferocytosis-related scores. The expression of TGFB3 key genes was validated via RT-PCR and western blotting. Further validation included Transwell, Wound healing, Colony formation, and EDU assays. We formulated and validated an efferocytosis-related genes risk model in bladder cancer, comprising 13 core genes. The risk model demonstrated autonomous prognostic significance in both univariate and multivariate Cox analyses. Following the multivariate analysis, we devised a nomogram. Moreover, by utilizing individual risk scores derived from this risk model, we successfully stratified patients into two discernible risk cohorts, unveiling noteworthy variances in immune infiltration profiles and responsiveness to immunotherapy. Notably, the model's key gene TGFB3 was validated through comprehensive experimental investigations, including Transwell assays for migration and invasion and Wound healing assays for motility on the T24 and BIU cell lines.

The present study examined the levels of MMP-2, MMP-9, VEGF, bFGF and CD105 to elucidate the relationship among them and associated clinical features in the given cohort of non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC) patients. Real time-quantitative PCR was done to examine the gene expressions of MMP-2, MMP-9, VEGF, bFGF and CD105 in 70 NMIBC and 40 MIBC patients. Western blotting and immunohistochemical staining were done to check their immunolevels followed by statistical analyses of their expressions with patients' demographic variables. Scanning electron microscopic (SEM) studies were done in representative non-muscle and muscle invasive tumor specimens to elucidate the tumor vasculature and extent of neoangiogenesis. The study reported an increase in gene expression and immunolevels of MMP-2, MMP-9, VEGF, bFGF and CD105-MVD with tumor stage and tumor grade. Statistical studies examined the relevant associations of their expressions with tumor stage, tumor grade, tumor size, tumor type, and tobacco chewing/smoking history of patients. SEM studies revealed marked differences in the vascular architecture and their spatial distribution indicated by increase in vascular density, vascular sprout proliferation and new blood vessel formation with tumor stage and tumor grade. The discriminatory ability of MMP-2, MMP-9, VEGF, bFGF and CD105-MVD in the diagnosis of NMIBC and MIBC was confirmed by ROC curve analysis which revealed the high sensitivity and low specificity of these markers in a given cohort of patients. Observed positive correlations of angiogenic markers with MMP-2 and MMP-9 in the given cohorts of NMIBC and MIBC patients explain their possible effects on bladder tumorigenesis via vascular angiogenesis. Cox regression (univariate and multivariate) and Kaplan-Meier along with log-rank survival analysis examined the strong expressions of these markers as the predictive indicators of poor survival probability (OS, RFS, PFS, and CSS) in 52 NMIBC and 36 MIBC patients. Significant associations of expressions of MMP-2, MMP-9, VEGF, bFGF and CD105-MVD with clinical variables emphasized their significance in diagnosis of NMIBC and MIBC patients.
