Project description:Aging and age-related pathologies can be delayed by specifically targeting the senescence-associated secretory phenotype (SASP), a hallmark feature of senescent cells. Achieving the goal using natural or synthetic agents would have a tremendous impact on the quality of lifespan and burden of age-related chronic diseases. We report the potential of rutin, a bioactive phytochemical component derived from natural plants specifically ginkgo boliva, in targeting senescent cells via suppression of the SASP. This study demonstrates the efficacy of rutin as medicinal agent in controlling the influence of senescent human stromal cells and provides a strong rationale for its future use in aging intervention and geriatric medicine.

Project description:Damage of the intestinal epithelial barrier by xenobiotics or reactive oxygen species and a dysregulated immune response are both factors involved in the pathogenesis of inflammatory bowel diseases (IBD). Curcumin and rutin are polyphenolic compounds known to have anti-oxidant and anti-inflammatory activities, but their mechanism(s) of action are yet to be fully elucidated. Mdr1a-/- mice spontaneously develop intestinal inflammation, predominantly in the colon, with pathology similar to IBD, so this mouse model is relevant for studying diet-gene interactions and potential effects of foods on remission or development of IBD. This study tested whether the addition of curcumin or rutin to the diet would alleviate colonic inflammation in mdr1a-/- mice. Using whole-genome microarrays, the effect of dietary curcumin on gene expression in colon tissue was also investigated. Twelve mice were randomly assigned to each of three diets; control (AIN-76A), control + 0.2% curcumin or control + 0.1% rutin and monitored from the age of 7 to 24 weeks. Curcumin, but not rutin, significantly reduced histological signs of colonic inflammation in mdr1a-/- mice. Microarray and pathway analyses suggested that the effect of dietary curcumin on colon inflammation could be via an up-regulation of xenobiotic metabolism and a down-regulation of pro-inflammatory pathways probably mediated by PXR and PPARï¡ activation of RXR. These results reveal the potential of global gene expression and pathway analyses to study and better understand the effect of foods in colonic inflammation. Experiment Overall Design: Twelve mice were randomly assigned to each of three diets; control (AIN-76A), control + 0â¢2% curcumin or control + 0â¢1% rutin and monitored from the age of 7 to 24 weeks. As only curcumin significantly reduced colonic HIS, comparison of the gene expression levels in colon was carried out using total RNA from colon tissue of four mdr1a-/- mice from the control group (high HIS) and four mdr1a-/- mice from the curcumin group (low HIS). A reference design with eight arrays was used for this comparison, where each individual RNA sample was hybridized in the array with the reference RNA, totalizing 4 biological replicates per treatment.

Project description:Human trisomies can alter cellular phenotypes and produce congenital abnormalities such as Down Syndrome (DS). Here we have generated induced pluripotent stem cells (iPSCs) from DS fibroblasts, and introduced a TKNEO transgene into one copy of chromosome 21 by gene targeting. When selecting against TKNEO, spontaneous chromosome loss was the most common cause for survival, with a frequency of ~10-4, while point mutations, epigenetic silencing, and TKNEO deletions occurred at lower frequencies in this unbiased comparison of inactivating mutations. Mitotic recombination events resulting in extended loss of heterozygosity were not observed in DS iPSCs. The disomic cells that we derived proliferated faster and produced more endothelia in vivo than their otherwise isogenic trisomic counterparts, but hematopoietic differentiation, pluripotency and survival were statistically unchanged. Our study describes the first targeted removal of a human trisomy, which could prove useful in both clinical and research applications. RNA samples were from two trisomic iPSC clone (C2-4, C3-5) and four derived disomic subclones (C2-4-3, C2-4-4 and C3-5-11, C3-5-13). Duplicate RNA samples from human embyonic stem cells (H1) were included as control.

Project description:Human iPSCs were differentiated towards an induced-SMC (iSMC) phenotype in a 10-day protocol. Proteomics was performed throughout the entire differentiation time course to provide a robust, well-defined starting and ending cell population. Proteomics data verified iPSC differentiation to iSMCs. Proteomics comparison with primary human SMCs showed a high correlation with iSMCs. After iSMC differentiation, we initiated calcification in the iSMCs by culturing the cells in osteogenic media for 17 days.

Project description:Corneal endothelial cells (CECs) are critical to maintaining clarity of the cornea. This study was initiated to develop peripheral blood mononuclear cells (PBMC)-originated induced pluripotent stem cells (iPSCs)-derived CECs. We isolated PBMC and programmed the mononuclear cells to generate iPSCs. Subsequently, the PBMC-originated iPSCs were differentiated to CECs. The morphology of differentiating iPSCs was examined at regular intervals by phase contrast microscopy. In parallel, the expression of pluripotent, and CECs-associated markers was investigated by quantitative real-time PCR (qRT-PCR). The molecular architecture of the iPSCs-derived CECs and human corneal endothelium (CE) were examined by mass spectrometry-based proteome sequencing. The PBMC-originated iPSCs expressed pluripotent-specific markers at levels similar to expression in H9 human embryonic stem cells (hESCs). Phase contrast microscopy illustrated that iPSCs-derived CECs are tightly adherent, exhibiting a hexagonal-like shape, one of the cardinal characteristics of CECs. The CECs-associated markers were expressed at many orders of magnitude higher in iPSCs-derived CECs at days 13, 20, and 30 compared to their respective levels in iPSCs. Importantly, only residual expression levels of pluripotency markers were detected in iPSCs-derived CECs. Mass spectrometry-based proteome profiling identified 10,575 proteins in iPSCs-derived CECs. In parallel, we completed proteome profiling of the human CE identifying 6345 proteins. Of these, 5763 proteins were identified in the iPSCs-derived CECs suggesting a 90.82% overlap between the iPSCs-derived CECs and human CE proteomes. Importantly, cryopreservation of iPSCs-derived CECs did not affect the tight adherence of CECs, and their hexagonal-like shape while expressing high levels of CECs-associated markers. We have successfully developed a personalized approach to generate CECs that closely mimic the molecular architecture of the human CE. To the best of our knowledge, this is the first report describing the development of PBMC-originated, iPSCs-derived CECs.

Project description:Ensartinib, an approved ALK inhibitor, is used as the first-line therapy for advanced ALK-positive non-small cell lung cancer in China. Ensartinib shows superior efficacy to crizotinib in both systemic and intracranial disease and is prepared to be reviewed overseas. In future, more patients would benefit from it based on its efficacy. However, a high incidence of hepatotoxicity has been observed in clinic, which often demands dose reduction or discontinuation of the drug, hampering its overall efficacy. Hence, it is inevitably valuable to study the mechanism which would be benefit to overcome the ensartinib-induced hepatotoxicity. In addition, based on the toxicity model, it is well established to understand the process of drug-induced liver injury and hepatic function-related molecules. Our findings discovered the level and location of TXNIP in liver homeostasis regulatory, clarified the molecular mechanism for ensartinib-induced hepatotoxicity and identified rutin as a potential strategy for the first time. We find a novel mode of rutin in intervening ROS production and apoptosis by binding TXNIP. Our study is of great significance to the basic theories and clinical practice. And this work is of broad interest to the readers from drug discovery, hepatologists in this filed and biologists in redox homeostasis.
