Non-coding small RNA expression analysis of rat pancreatic acinar cells(AR42J) treated with sodium taurocholate

Project description:Acute pancreatitis (AP) is a common digestive disorder with high morbidity and mortality. At present, the pathogenic mechanisms of AP remain unclear. Pancreatic acinar intracellular trypsinogen activation is considered to be an important cause of AP and is an important event in the early stages of AP. The activation of trypsinogen is a key factor for the pancreas to maintain normal function and that the abnormal activation of trypsinogen in pancreatic acinar cells is an initiating factor for the occurrence of AP. In the past decade, microRNA-related research results suggest that small non-coding RNAs play an important role in AP. Recently, endogenous transfer RNA-derived small RNA (tsRNA), a newly identified non-coding small RNA, is reported to be associated with multiple diseases. tsRNAs can be broadly classified into two main groups: tiRNAs (tRNA halves) and tRFs (tRNA-derived fragments). tiRNAs are produced by specific cleavage in the anticodon loop under various stress conditions (29-50 nucleotides). tRFs are separated to 4 subtypes by their sites of origin in pre-tRNA or mature tRNA, and generally shorter than tiRNAs (16-28 nucleotides). Similar to the function of microRNA, tsRNA can inhibit their functions by binding to target genes. However, the role of tsRNA in regulating AP pathogenesis has not been investigated. In this experiment, sodium taurocholate was used to treat the rat pancreatic acinar cell (AR42J) to establish the AP-related intracellular activation of trypsinogen model. Then we used RNA sequencing to identify the differentially expressed non-coding small RNAs including microRNA and tsRNA in the cell model.

RNA-Seq of explanted murine pancreatic acinar cells

Project description:To investigate the underlying changes during acinar-to-ductal metaplasia, pancreatic acinar cells were isolated from 5 week old KrasG12D-mice. RNA was isolated immediately after isolation (t=0 days) or after 3 days embedded in collagen.

Gene expression of non-apoptotic pancreatic acinar cell death with autophagy

Project description:Serine protease inhibitor Kazal type 3 (Spink3) is a trypsin inhibitor in the pancreas. Spink3-/- pancreatic acinar cells are dead with excessive autophagy at birth (p0.5). To prove the role of nonapoptotic cell death with autophagy, we generated by transgenic technology the pancreas of Spink3-/-;XKI/+ mice contained both normal and dying acinar cells with autophagy. In this new mouse model, chronic inflammation occurred in the pancreas, indicating that some signals from nonapoptotic dead cell induce chronic inflammation in the pancreas. All samples were the pancreas at p0.5. Sample 1 and 2 are the pancreas from wild type (Spink3+/+, control) mice. Sample 3 and 4 are the pancreas from Spink3-/-, which all pancreatic acinar cells show induced nonapoptotic cell death with autophagy. Sample 5 and 6 are the pancreas from Spink3-/-XKI/+, about half acinar cells are normal, but other acinar cells show induced nonapoptotic cell death with autophagy.

Epigenetic reprogramming in pancreatic acinar cell in the absence of MIST1

Project description:Epigenetic profile of tissues is reprogrammed under diseased conditions. H3K4Me3 and H3K27Me3 represent active and repressive epigenetic marks, respectively. ChIP-seq is an effective tool to study global protein-DNA interactions. To study global epigenetic differences, we used H3K4Me3 antibody to evaluate its enrichment in pancreatic acinar cells of WT and Mist1-/- mice followed by next generation sequencing. We found specific hotspots that showed differential enrichment for H3K4Me3 both in WT and Mist1-/- mice. The data show that pancreatic acinar cells are epigenetically reprogrammed under stressed cellular conditions. Global H3K4Me3 profiling of WT and Mist1-/- pancreatic acinar cells using ChIP-seq.

PHARMACOLOGICAL INHIBITION AND REVERSAL OF PANCREATIC ACINAR DUCTAL METAPLASIA

Project description:Acinar ductal metaplasia (ADM), is believed to be one of the earliest precursor lesions towards the development of pancreatic ductal adenocarcinoma, and maintaining the pancreatic acinar cell phenotype suppresses tumor formation. We report that pStat3 and HDAC inhibition can attenuate ADM in vitro and TSA treatment reverses the dedifferentiated phenotype to one that is more acinar. Our findings suggest that pharmacological inhibition or reversal of pancreatic ADM represents a potential therapeutic strategy for blocking ductal reprogramming of acinar cells.

RNA-seq of purified human pancreatic dedifferentiated acinar cells and duct cells

Project description:Pancreatic acinar cells can dedifferentiate upon tissue injury and acquire ductal characteristics. This acquisition of duct cell features is critical in tumor development. Nevertheless, duct cells themselves are less prone for development of PDAC (pancreatic ductal adenocarcinoma) than dedifferentiated acini. We aimed to clarify which genes are unique for dedifferentiated acini. Mixed exocrine preparations of acinar and duct cells were obtained from human pancreatic donor organs and cultured to induce dedifferentiation. We lineage-labeled and FACS-purified these human dedifferentiated acinar cells and compared them to duct cells from the same donor (n=5).
