  • Title: Abnormal Expression of miR-21 and miR-95 in Cancer Stem-Like Cells is Associated with Radioresistance of Lung Cancer.
    Author: Zhang J, Zhang C, Hu L, He Y, Shi Z, Tang S, Chen Y.
    Journal: Cancer Invest; 2015 May; 33(5):165-71. PubMed ID: 25831148.
    Abstract:
    This study demonstrated that miR-21 and miR-95 expression were significantly higher in the ALDH1(+)CD133(+)subpopulation than in the ALDH1(-)CD133(-) subpopulation of lung cancer cells. Combined delivery of anti-miR-21 and anti-miR-95 by calcium phosphate nanoparticles significantly inhibited tumor growth in a xenograft tumor model and sensitized radiotherapy. The anti-miRNAs significantly reduced miR-21 and miR-95 levels, increased PTEN, SNX1, and SGPP1 protein expression, but reduced Akt Ser(473) and Thr(308) phosphorylation. ALDH1(+)CD133(+) subpopulation of NSCLC tumor cells confers radioresistance due to high expression of miR-21 and miR-95. Targeting inhibition of miR-21 and miR-95 can inhibit tumor growth through elevating PTEN, SNX1, and SGPP1 expression and inhibiting Akt phosphorylation.
