Transcription profiling of mouse cell lines immune sensitive P0 and immune resistant P3 identifies a tumor immune evasion mechanism using P0 and P3 cell lines


ABSTRACT: The emergence of immune resistance variants during immunotherapy is poorly understood. We generated a highly immune resistant cell line (P3) from a susceptible cell line (P0) by subjecting it to 3 rounds of in vivo immune selection. Subsequently, microarray analysis of P0 and P3 was performed to identify genes that may contribute to the increase in immune resistance. Experiment Overall Design: Four experimental replicates were prepared for each cell line. P0 is the control cell line, and P3 is the experimental/resistant cell line.

Immune escape is an important reason why the immune system cannot control tumor growth, but how escape variants emerge during immunotherapy remains poorly understood. Here, we identify a new mechanism of tumor immune escape using an in vivo selection strategy. We generated a highly immune-resistant cancer cell line (P3) by subjecting a susceptible cancer cell line (P0/TC-1) to multiple rounds of in vivo immune selection. Microarray analysis of P0 and P3 revealed that vascular cell adhesion molec  ...[more]
