Transcription profiling of human neuro-invasive pancreatic tumors engineered in-vitro compared to less invasive parental cells

Perineural invasion (PNI) is considered to be a specific path for the spread of pancreatic cancer cells and PNI is thought to be one of the important factors that determine local recurrence after resection. In addition PNI has been implicated in the pain syndrome that affects the majority of pancreatic ductal adenocarcinoma (PDAC) patients. Here we aimed to investigate the transcriptional differences between neuro-invasive tumors engineered in-vitro compared to less invasive parental cells. Two colour differential hybridisations were performed with human universal reference total RNA (Clontech, #636538).
