Bulk RNA-sequencing analyses of multi-stroma flow-sorted from cocultures with murine pancreatitis (P)-derived organoids, PDAC organoids, or PDAC organoids following initial coculture with P organoids (ie P-to-PDAC or sequential).

ABSTRACT: We investigated the transcriptomic differences of multi-stroma flow-sorted from cocultures with murine pancreatitis (P)-derived organoids, PDAC organoids, or PDAC organoids following initial coculture with P organoids (ie P-to-PDAC or sequential).

Analysis of pancreatitis-derived organoids and PDAC organoids cocultured with multi-stroma

Project description:We investigated the crosstalk between cocultures of pancreatitis (P)-derived organoids (P1 or P5) or PDAC organoids (T6-LOH or T13-LOH) and multi-stroma (pancreatic stellate cells PSC5, pancreatic fibroblasts FIBRO27 and mesothelial cells M-G1).

Analysis of murine normal pancreatic organoids, pancreatitis-derived organoids, and PDAC organoids in complete media and of pancreatitis-derived organoids, and PDAC organoids cultured alone or cocultured with pancreatic stellate cells in reduced media

Project description:We investigated the differences between murine normal pancreatic organoids (N), pancreatitis-derived organoids (P), and PDAC organoids cultured in completed media (i.e., mCPLT). We also studied the crosstalks between P and PDAC organoids and PSCs when they are cocultured together (i.e., cocx) or in monoculture (i.e., monocx) in reduced media.

Gene expression of matched treatment-naive versus FOLFIRINOX-treated PDAC patient-derived organoids

Project description:In our study, we aimed to investigate adaptive processes of tumors under treatment and therefore, generated PDAC patient-derived organoids (PDOs) and 2D cell lines before and after chemotherapy. We enrolled a patient with borderline resectable PDAC who received neoadjuvant FOLFIRINOX. Endoscopic fine needle (pre-FFX) and surgical biopsies (post-FFX) were used to generate PDOs and 2D cells. Whole exome sequencing (WES) and RNA sequencing data of the pre-FFX and post-FFX organoids were compared in order to evaluate the genetic landscape and PDAC subtypes. Although transcriptional subtyping classified both PDOs as classical PDAC, gene set enrichment analysis (GSEA) revealed a reduced pathway activation linked to the basal-like phenotype such as KRAS signaling in the post-FFX organoids. WES did not show major differences in the genetic landscape of the tumor pre- and post-FFX induction suggesting a plasticity process rather than a clonal selection during chemotherapy. 2D cells were subjected to an unbiased automated drug screening of 415 compounds to investigate FFX-induced vulnerabilities. Top targets such as MEK inhibitors were validated manually in the 2D cells and organoids and an increased sensitivity was observed in the post-FFX cells. Thus, integrating functional layers into personalized medicine allows to identify chemotherapy-induced vulnerabilities as potent targeted therapy options in PDAC.

SOAT1 knock-out downregulates the expression of mevalonate pathway genes in PDAC organoids

Project description:One of the emerging cancer vulnerabilities is altered metabolism, and several metabolic pathways have been shown to promote pancreatic ductal adenocarcinoma (PDAC). Here we use genetic targeting to delete SOAT1 from murine PDAC metastasis organoids, and use RNA-seq to identify genes differentially regulated in normal and cholesterol-supplemented media conditions in the presence or absence of SOAT1.

scRNA-seq of patient-derived PDAC organoids

Project description:We derived PDAC organoids from primary tumors of 18 patients, together with two matched samples from liver metastases. By single-cell RNA sequencing, we show that PDAC organoids consist of ductal cells with patient-specific expression of several gene groups, including genes which encode cell surface proteins. We report Ã¢Â€Â˜classicalÃ¢Â€Â™ and Ã¢Â€Â˜basal-likeÃ¢Â€Â™ cells coexisting within single primary tumors or metastases, with greater intratumor subtype heterogeneity linked to higher tumor grade. Single-cell transcriptome analysis of PDAC organoids and primary PDAC identified distinct tumor cell states shared across patients, including a cycling progenitor cell state and a differentiated secretory state. We show that these cell states are connected by a differentiation hierarchy, with Ã¢Â€Â˜classicalÃ¢Â€Â™ subtype cells concentrated at the endpoint of this hierarchy.

Inhibition of ketohexokinase C isoform impairs the development of PDAC tumors

Project description:the genetic inactivation of Khk-C enhanced the survival of KPC-driven PDAC model even in absence of high fructose diet. Moreover Khk-C knock out decreased the viability of KPC organoids and cancer cells, the migratory capability of PDAC cells in vitro and the growth of KPC cells in vivo in a cell autonomous manner.

RNA-sea of Smad4 wild-type or Smad4 knockout KvPC PDAC organoids from monocultures or co-cultures with pancreatic stellate cells and RNA-seq of flow-sorted PSCs from the same co-cultures.

Project description:RNA-sequencing of flow-sorted Smad4 wild-type (WT) or Smad4 knockout (KO) KvPC (i.e. KRASG12V; p53 mutant) pancreatic ductal adenocarcinoma (PDAC) organoids from monocultures or co-cultures with pancreatic stellate cells (PSCs) and RNA-sequencing of flow-sorted PSCs from the same co-cultures. We investigated changes in transcriptome in Smad4 KO KvPC PDAC organoids compared to Smad4 WT KvPC PDAC organoids in monoculture or in co-culture with PSCs. We also investigated the changes in transcriptome in PSCs co-cultured with Smad4 WT or Smad4 KO KvPC PDAC organoids.
