Project description:KrÜppel-like factor 10 (KLF10), deficient in two thirds of 105 resected pancreatic adenocarcinoma (PDAC) patients, was associated with rapid loco-regional recurrence and large tumor size. Additional KLF10 depletion in KC (LSL: KrasG12D; Pdx1-CRE) mice accelerated progression from pancreatic intraepithelial neoplasia to PDAC. In Panc-1 cells with KLF10 deficiency (Panc-1-pLKO-shKLF10), increased sphere formation, stem cell markers expression, and tumor growth were noted compared with those of control. Over-expressing KLF10 genetically or pharmacologically using metformin, reversed the stem cell phenotypes induced by KLF10 depletion. Ingenuity pathway analysis and gene set enrichment analysis showed Notch signal molecules including Notch receptors 3 and 4 were over-expressed in Panc-1-pLKO-shKLF10. KLF10 transcriptionally suppressed Notch 3 and 4 receptors by competing with ELF3, a positive regulator, for promoter binding. Downregulating Notch signal genetically or pharmacologically ameliorated stem cell phenotypes of Panc-1-pLKO-shKLF10. Elevating KLF10 expression by metformin with concomitant evodiamine, a non-toxic Notch 3 methylation stimulator, delayed murine tumor growth of PDAC with KLF10 deficiency without prominent toxicity. These results demonstrated a novel signal pathway of KLF10 in modulating stem cell phenotypes of PDAC via transcriptional regulating Notch signal pathway. Elevating KLF10 and suppressing Notch signal may cooperatively reduce PDAC tumorigenesis and malignant progression.

Project description:Nonalcoholic steatohepatitis (NASH), characterized by hepatic steatosis, inflammation, and liver injury, has become a leading cause of end-stage liver diseases and liver transplantation. Krüppel-like factors 10 (KLF10) is a Cys2/His2 zinc finger transcription factor that regulates cell growth, apoptosis, and differentiation. However, whether it plays a role in the development and progression of chronic liver diseases like NASH remains poorly understood. In the present study, we found that KLF10 expression was selectively upregulated in the mouse models and human patients with NASH, compared with simple steatosis (NAFL). Gain- and loss-of function studies demonstrated that hepatocyte-specific overexpression of KLF10 aggravated, whereas its depletion alleviated diet-induced NASH pathogenesis in mice. Mechanistically, transcriptomic analysis and subsequent functional experiments showed that KLF10 promotes hepatic lipid accumulation and inflammation through the palmitoylation and plasma membrane localization of fatty acid translocase CD36 via transcriptionally activation of zDHHC7. Indeed, both expression of zDHHC7 and palmitoylation of CD36 are required for the pathogenic roles of KLF10 in NASH progression. Thus, our results identify an important role for KLF10 in NAFL-to-NASH development through zDHHC7-mediated CD36 palmitoylation.

Project description:Exercise is recognized to be an effective way in the combat against obesity and related metabolic disorders, but the underlying mechanism is incompletely understood. Krüppel-like factor 10 (KLF10) is a transcription factor participating in diverse biological processes. KLF10 expression is abundant in adipose tissue, but its role in obesity is not well defined. Here, we show that exercise could facilitate adipocyte-derived KLF10 expression via the SIRT1/FOXO1 pathway. Adipocyte-specific knockout of KLF10 (KLF10AKO) blunts exercise-promoted white adipose browning, energy expenditure, fat loss, and glucose tolerance in diet-induced obese (DIO) mice. On the contrary, adipocyte-specific transgenic expression of KLF10 in mice (KLF10ATG) enhanced the abovementioned metabolic benefits induced by exercise. Mechanistically, KLF10 interacts with FOXO1 and facilitates the recruitment of KDM4A to form a ternary complex on the promoter regions of the Pnpla2 and Lipe genes to promote the expression of these key lipolytic genes, therefore facilitating lipolysis to defend against DIO in mice. As a newfound downstream effector responding to exercise, adipose KLF10 could act as a potential target in the fight against obesity

Project description:Perivascular fibrosis, characterized by increased amount of connective tissue around vessels, is a hallmark for vascular disease. Angiotensin II (Ang II) contributes to vascular disease and end-organ damage via promoting T-cell activation. Despite recent data suggesting the role of T cells in the progression of perivascular fibrosis, the underlying mechanisms are poorly understood. Kruppel-like Factor 10 is a transcription factor expressed in T cell subsets. We sought to investigate the role of KLF10 in CD4+ T cells in regulating vascular damage in an AngII mouse model. CD4-targeted KLF10 deficient (TKO) and CD4-Cre (WT) mice were generated and subjected to 28 days of Ang II infusion. Differential gene expression profiling of non-stripped aorta, stripped aorta, isolated aortic fibroblasts from CD4-Cre (Cre) or CD4-Cre KLF10-fl/fl mice(TKO) mice after 28 days Angiotensin II (Ang II) treatment were performed to ascertain the underlying global transcriptomic changes involved in perivascular fibrosis. Since increased IL-9 is a profibrotic cytokine, we hypothesized that perivascular fibrosis might be rescued by administration of anti-IL-9 neutralizing monoclonal antibodies (mAbs) in Ang II-treated TKO mice. Then differential gene expression profiling of non-stripped aorta from TKO mice with or without anti-IL9-antibody treatment after 28 days Ang II infusion. To further understand the differences in phenotypic heterogeneity in fibroblasts during the progression of perivascular fibrosis between TKO and control mice in response to Ang II treatment, we performed single-cell RNA-sequencing (scRNA-seq) of the descending aorta. Collectively, comparative RNA-seq transcript profiling identified several pathways associated with periadventitial remodeling and that the calcium signaling pathway is dominantly upregulated in non-stripped aortas of TKO mice after Ang II treatment. Indeed, the profibrotic genes Col8a1, Mmp2, Fmod, and Angptl1, which were identified as significantly increased in TKO aortas and in isolated fibroblasts by both bulk RNA seq and scRNA seq, were all decreased after treatment with anti-IL-9 mAbs. These results indicate that the KLF10-IL-9 signaling axis in CD4+ T cells tightly regulate the processes of Ang II-induced pathological perivascular fibrosis and provide novel therapeutic opportunities for the treatment of hypertensive-associated diseases. 1) Differential gene expression profiling of non-stripped aotra, stripped aorta, aortic fibroblasts from CD4-Cre(Cre) or CD4-Cre KLF10-fl/fl mice(TKO) mice after 28 days Angiotensin II (Ang II) treatment. 2) Differential gene expression profiling of non-stripped aotra from TKO mice with or without anti-IL9-antibody treatment after 28 days Ang II infusion. 3) Single cell RNA-sequencing was perform on descending aorta from Cre or TKO after Ang II treatment.
