Project description:Kidney organoids are ideal models to study the complex process of human kidney development. Here we report the generation of functional kidney organoids by reprogramming human urine epithelial cells (hUCs). RNA-seq and ATAC-seq revealed the three-stage process of the 2D U-iRO induction. Single cell RNA-seq further reveals the cell types in 2D and 3D organoids, 2D U-iRO dominated with mesenchyme and 3D U-iRO with tubule.

Project description:Two-dimensional (2D) culture models are commonly used in cancer research, but fail to recapitulate complex mechanical cues of native tissues. In this study, we developed an ex vivo three-dimensional (3D) lung cancer model by seeding human lung adenocarcinoma cells into decellularised rat lungs and culturing them in a pressure chamber and perfusion system mimicking respiratory motion (RM) and blood flow. In 3D culture, RM promoted cell adhesion and proliferation, enhanced the nuclear translocation of β-catenin and YAP, and increased the expression of integrin β1 and E-cadherin. In addition, upregulation of extracellular matrix- and cell adhesion-related genes was particularly notable. In contrast, in 2D culture, RM suppressed cell proliferation and induced apoptosis, with prominent upregulation of tumour suppressor genes. Our findings demonstrate that dimensionality and mechanical stress synergistically influence lung cancer cell dynamics and underscore the need for 3D models in cancer research that closely replicate the native lung tissue microenvironment.

Project description:Background: Prostate cancer is the second leading cause of cancer mortality among US men. Epidemiological evidence suggests that high vitamin D status protects men from prostate cancer and the active form of vitamin D, 1α,25 dihydroxyvitamin D3 (1,25(OH)2D) has anti-cancer effects in cultured prostate cells. Still, the molecular mechanisms and the gene targets for vitamin D-mediated prostate cancer prevention are unknown. Results: We examined the effect of 1,25(OH)2D (+/- 100 nM, 6, 24, 48 h) on the transcript profile of proliferating RWPE1 cells, an immortalized, non-tumorigenic prostate epithelial cell line that is growth arrested by 1,25(OH)2D (Affymetrix U133 Plus 2.0, n=4/treatment per time and dose). Our analysis revealed many transcript level changes at a 5% false detection rate: 6 h, 1571 (61% up), 24 h, 1816 (60 % up), 48 h, 3566 (38 % up). 288 transcripts were regulated similarly at all time points (182 up, 80 down) and many of the promoters for these transcripts contained putative vitamin D response elements. Functional analysis by pathway or Gene Set Analysis revealed early suppression of WNT, Notch, NF-kB, and IGF1 signaling. Transcripts related to inflammation were suppressed at 6 h (e.g. IL-1 pathway) and suppression of proinflammatory pathways continued at later time points (e.g. IL-17 and IL-6 pathways). There was also evidence for induction of anti-angiogenic pathways and induction of transcripts for protection from oxidative stress or maintenance of cell redox homeostasis at 6 h. Conclusions: Our data reveal of large number of potential new, direct vitamin D target genes relevant to prostate cancer prevention. In addition, our data suggests that rather than having a single strong regulatory effect, vitamin D orchestrates a pattern of changes within prostate epithelial cells that limit or slow carcinogenesis. Experiment Overall Design: RWPE1 cells were treated with medium containing 100 nM of 1,25(OH)2D or vehicle (0.1% ethanol) for 6, 24 or 48 hours (n=4 per treatment, 24 total samples). The transcripts levels in each sample were measured by using the Affymetrix HU133 plus 2.0 GeneChip (Affymetrix, Santa Clara, CA).

Project description:Liver has abundant regenerative capacity, but hepatocytes cannot be cultured long-term in vitro. Activation of FXR signaling induced iHOs with both hepatocyte traits and proliferative potential. To investigate the transcriptomic analysis of iHOs, we performed bulk RNA-seq analysis of organoids in different passages and single cell RNA-seq analysis of iHOs. Compared to 2D-iPS-Heps and organoids in other culture conditions, iHOs have expression profiles more similar to primary human hepatocytes and human fetal liver cells. Single cell RNA-seq revealed iHOs have a fraction that co-expresses hepatocyte markers and proliferation markers.
