Abstract :
[en] Peroxisomes are ubiquitous organelles formed by peroxisome biogenesis (PB). During PB, peroxisomal matrix proteins harboring a peroxisome targeting signal (PTS) are imported inside peroxisomes by peroxins, encoded by PEX genes. Genetic alterations in PEX genes lead to a spectrum of incurable diseases called Zellweger spectrum disorders (ZSD). In vitro drug screening is part of the quest for a cure in ZSD by restoring PB in ZSD cell models. In vitro PB evaluation is commonly achieved by immunofluorescent staining or transient peroxisome fluorescent reporter expression. Both techniques have several drawbacks (cost, time-consuming technique, etc.) which we overcame by developing a third-generation lentiviral transfer plasmid expressing an enhanced green fluorescent protein fused to PTS1 (eGFP-PTS1). By eGFP-PTS1 lentiviral transduction, we quantified PB and peroxisome motility in ZSD and control mouse and human fibroblasts. We confirmed the stable eGFP-PTS1 expression along cell passages. eGFP signal analysis distinguished ZSD from control eGFP-PTS1-transduced cells. Live eGFP-PTS1 transduced cells imaging quantified peroxisomes motility. In conclusion, we developed a lentiviral transfer plasmid allowing stable eGFP-PTS1 expression to study PB (deposited on Addgene: #133282). This tool meets the needs for in vitro PB evaluation and ZSD drug discovery.
