Gene expression signatures associated with Perineural Invasion in pancreatic ductal adenocarcinoma

Project description:Perineural invasion (PNI) is a prominent characteristic of pancreatic ductal adenocarcinoma (PDAC) and indicates poor prognosis. The invasion of the surrounding nerves by pancreatic cancer cells not only provides route for metastasis but also contributes to neural remodeling and changes in the neuronal milieu that can profoundly influenced the microenvironment of pancreatic cancer. To investigate the downstream molecules associated with PNI, the experiment analyzed mRNA expression of 50 pairs of pancreatic ductal adenocarcinoma tissue and paired adjacent non-tumor tissue, among which 28 pairs of cases diagnosed with PNI by experienced pathologist. Results provide new insight into molecular basis for the influence of PNI on the microenvironment of pancreatic cancer.

Gene expression level of HEI-286 Schwann cells and MiaPaCa-2 pancreatic cancer cells

Project description:We report the transcriptome analysis of HEI-286 human Schwann cells and MiaPaCa-2 pancreatic cancer cells Nerves stimulate cancer progression for different cancer types, promoting both tumor growth and perineural invasion, a prominent process in pancreatic ductal adenocarcinoma. Yet little is known about how cells in the nerves contribute to cancer progression. Here we demonstrate that Schwann cells, the most abundant cell type in nerves, collectively function as tumor activated Schwann cell tracks (TASTs). Schwann cells in a 3D matrix organize into stellate tracks which serve as a conduit for cancer cell migration. TASTs actively promote pancreatic cancer dissemination during perineural invasion and neoneurogenesis. This key function of TASTs is induced by cancer cells triggering c-Jun activation of Schwann cells, analogous to the reprogramming that promotes nerve repair. In TASTs, dynamic Schwann cell processes wrap around and apply forces directly on cancer cells to enhance cancer motility. We define a model of cancer progression that relies upon collective Schwann cell behavior driven by c-Jun transcriptional reprogramming.

Cancer-Associated Fibroblasts Shape a High-Lactate Microenvironment to Drive Perineural Invasion in Pancreatic Cancer via Histone Lactylation

Project description:Perineural invasion (PNI) is a pivotal prognostic factor in pancreatic cancer, associated with aggressive tumor behavior and adverse patient outcomes. Despite its recognized clinical impact, the molecular mechanisms underlying PNI are not well understood. In this study, we isolated perineural invasion-associated cancer-associated fibroblasts (pCAFs), which demonstrated a markedly enhanced capacity to promote neural invasion in pancreatic cancer compared to non-perineural invasion-associated CAFs (npCAFs). Utilizing single-cell, high-throughput sequencing, and metabolomics, we identified a significant upregulation of glycolysis in pCAFs, fostering a high-lactate tumor microenvironment conducive to cancer progression. pCAFs-derived lactate is absorbed by tumor cells, facilitating histone H3K18 lactylation. This epigenetic modification activates the transcription of neural invasion-associated genes such as L1CAM and SLIT1, thereby driving PNI in pancreatic cancer. Further exploration of metabolic reprogramming in pCAFs revealed enhanced acetylation of the glycolytic enzyme GAPDH, correlated with increased enzymatic activity and glycolytic flux. Targeting of GAPDH and lactylation modifications significantly inhibits neural invasion in a KPC mouse model. Clinical data suggested that high levels of H3K18 lactylation correlate with severe PNI and poorer patient prognosis. Our findings provide critical insights into the role of pCAFs in the PNI of pancreatic cancer, highlighting glycolytic reprogramming and lactate-driven histone modifications as potential therapeutic targets for PDAC.

Expression data of MIAPaCa-2 cells transfected with NDRG1

Project description:NDRG1 functions as a metastasis suppressor in pancreatic and other cancers. To determine the molecular function of NDRG1 in MIAPaCa-2 pancreatic cancer cells, we performed a whole genome gene array analysis on these cells stably transfected with NDRG1 when compared to empty vector-transfected controls. The differentially expressed genes indetified in this microarray may represent potential molecular targets of NDRG1 in pancreatic cancer. Two separate RNA extracts of MIAPaCa-2 vector control and NDRG1 transfected cells were collected and hybridised to Affymetrix Human Genome U133 Plus 2.0 chips.

Expression of microRNAs and Protein-coding Genes Associated with Perineural Invasion in Prostate Cancer

Project description:BACKGROUND. Perineural invasion (PNI) is the dominant pathway for local invasion in prostate cancer. To date, only few studies have investigated the molecular differences between prostate tumors with PNI and those without it. METHODS. To evaluate the involvement of both microRNAs and protein-coding genes in PNI, we determined their genome-wide expression with a custom microRNA microarray and Affymetrix GeneChips in 50 prostate adenocarcinomas with PNI and 7 without it. In-situ hybridization and immunohistochemistry was used to validate candidate genes. RESULTS. Unsupervised classification of the 57 adenocarcinomas revealed two clusters of tumors with distinct global microRNA expression. One cluster contained all non-PNI tumors and a subgroup of PNI tumors. Significance analysis of microarray data yielded a list of microRNAs associated with PNI. At a false discovery rate (FDR) < 10%, 19 microRNAs were higher expressed in PNI tumors than in non-PNI tumors. The most differently expressed microRNA was miR-224. In-situ hybridization showed that this microRNA is expressed by perineural cancer cells. The analysis of protein-coding genes identified 34 transcripts that were differently expressed by PNI status (FDR <10%). These transcripts were down-regulated in PNI tumors. Many of those encoded metallothioneins and proteins with mitochondrial localization and involvement in cell metabolism. Consistent with the microarray data, perineural cancer cells tended to have lower metallothionein expression by immunohistochemistry than nonperineural cancer cells. CONCLUSIONS. Although preliminary, our findings suggest that alterations in microRNA expression, mitochondrial function, and cell metabolism occur at the transition from a non-invasive prostate tumor to a tumor with PNI.
