    ..This work demonstrates that signaling through specific matrix-binding beta1 integrins (i.e., alpha5beta1) resulting from exaggerated deposition in lung of the matrix glycoprotein fibronectin might promote lung carcinoma cell growth. ..
  2. Han S, Khuri F, Roman J. Fibronectin stimulates non-small cell lung carcinoma cell growth through activation of Akt/mammalian target of rapamycin/S6 kinase and inactivation of LKB1/AMP-activated protein kinase signal pathways. Cancer Res. 2006;66:315-23 pubmed
    ..Taken together, these observations suggest that fibronectin-induced stimulation of NSCLC cell proliferation requires activation of the Akt/mTOR/p70S6K pathway and is associated with inhibition of LKB1/AMPK signaling. ..
  3. Han S, Roman J. COX-2 inhibitors suppress lung cancer cell growth by inducing p21 via COX-2 independent signals. Lung Cancer. 2006;51:283-96 pubmed
    ..These observations unveil a mechanism for p21 gene regulation by COX-2 inhibitors in lung carcinoma cell growth and this pathway represents a potential target for therapy. ..

    ..These observations unveil a mechanism for p21 gene regulation in lung carcinoma that represents a potential target for therapy. ..

    ..In summary, our results demonstrate that PPARgamma ligands inhibit Fn gene expression in NSCLC cells through PPARgamma-dependent and -independent pathways that affect both CREB and Sp1. ..
