MicroRNA profile of tumorigenic cells during formation of pulmonary adenocarcinoma

ABSTRACT: Study designed to obtain microRNA profile of tumorigenic Sca-1+CD34+ cells during the formation of pulmonary adenocarcinoma. After intranasal infection with adenovirus CRE (Ad-Cre), lung adenocarcinoma was identified pathologically in Lox-stop-lox Kras (LSL-Kras) G12D mice. Sca-1+CD34+ cells were sorted by flow cytometry and tested for the tumor-initiating ability to undergo self-renewal and differentiation. MiRNA profile was obtained from the microarray and further confirmed by qRT-PCR.The function of miRNAs was predicted bioinformatically, and miR-294 was verified to explore its relationship with tumor migration and invasion. We taken lung tissues from the LSL-Kras G12D mouse on the 0, 15th, 30th days, and defined as Group A, B, C respectively. These 3 samples were analyzed. Each kind of
