Gene expression of leaders and laggers MiaPaCa-2 pancreatic cancer cells during perineural invasion

ABSTRACT: To investigate the mechanisms of cancer cell migration during perineural invasion in pancreatic cancer, we injected fluorescently labelled MiaPaCA-2 cells in the sciatic nerves and collected the leader and lagger cells.

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.

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.

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.

Translational control of mTOR/4E-BP1 axis in MiaPaca-2 cells

Project description:Pancreatic ductal adenocarcinoma (PDAC) relies on hyper-activated protein synthesis. Consistently, human and mouse PDAC lose expression of the translational repressor and mTOR target 4E-BP1. Using genome-wide polysome-profiling, we here explore mRNAs whose translational efficiencies depend on the mTOR/4E-BP1 axis in Miapaca-2 cells. This was performed by isolating cytoplasmic and efficiently translated (heavy polysome-associated) mRNAs from MiaPaca-2 cells upon PP242-mediated mTOR inhibition

RNA-seq analysis lncRNA and mRNA between crushed sciatic nerves and intact contralateral nerves

Project description:To investigate the potential function of lncRNAs in Schwann cell (SCs) response to sciatic nerve damage and repair, we extracted the total RNA of crushed sciatic nerves and intact contralateral nerves for RNA-sequencing (RNA-seq). A total of 98 differentially expressed lncRNAs (including 46 up-regulated and 52 down-regulated lncRNAs) and 77 differentially expressed mRNAs (including 55 up-regulated and 22 down-regulated mRNAs) were identified between crushed sciatic nerves and normal control (log 2 FC > 1 and p < 0.001).

Transcription profiling of 8 months and 24 months old rat radial and sciatic nerves

Project description:The objective of this study was to determine which pathways are significantly regulated with age in sciatic and radial nerves, individually or considering the interaction term. We find a strong signature of the cholesterol biosynthesis pathway being downregulated with age in both nerves, however, this effect is significantly milder in the radial nerve. We collected both radial and sciatic nerves from 8 adult (8 months old) and 8 old (24 months old) rats.
