Transcription profiling of human HEK293 cells transfected with either wild type or delta exon 4 mutants of surfacant protein C

ABSTRACT: Mutations in the gene encoding surfactant protein C (SFTPC) have been linked to interstitial lung disease in children and adults. Expression of the index mutation, SP-Cdeltaexon4, in transiently transfected cells and type II cells of transgenic mice resulted in misfolding of the proprotein, activation of ER stress pathways and cytotoxicity. In the current study we show that stably transfected cells adapted to chronic ER stress imposed by constitutive expression of SP-Cdeltaexon4 via an NF-kB-dependent pathway. However, infection of cells expressing SP-Cdeltaexon4 with respiratory syncytial virus resulted in significantly enhanced cytotoxicity associated with accumulation of the mutant proprotein, pronounced activation of the unfolded protein response and cell death. Adaptation to chron
