An optimized QIAzol-based protocol for simultaneous miRNA, RNA, and protein isolation from precision-cut lung slices (PCLS).

ABSTRACT: Precision-cut lung slices (PCLS) are ex vivo models with preserved lung cell populations and maintained tissue architecture. PCLS are, therefore, a powerful tool in respiratory research to study molecular mechanisms that closely reflect whole tissue biology. High-quality RNA and protein extraction from PCLS is, however, challenging as agarose significantly interferes with the yield and purity of extracted material. The present study aimed to optimize QIAzol-based isolation protocol for high-yield and quality RNA, miRNA, and protein extraction from PCLS. PCLS were prepared from 10 to 15-week-old Wistar rats and cultured for 7 days in Dulbecco's Modified Eagle Medium/Nutrient Mixture F-12 (DMEM/F-12) supplemented with 0.1% FBS, penicillin, and streptomycin.
