MiR-152 suppresses the proliferation and invasion of NSCLC cells by inhibiting FGF2

Cheng Z, Ma R, Tan W, Zhang L

MicroRNAs (miRNAs) regulate the proliferation and metastasis of cancer cells. Here, we showed that miR-152 was downregulated in non-small-cell lung cancer (NSCLC) tissues and cell lines. Overexpression of miR-152 suppressed...

Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) Augments Acute Lung Injury via Its Neutrophil Priming Effects

Choi JC, Jung JW, Kwak HW, Song JH, Jeon EJ, Shin JW, Park IW, Choi BW, Kim JY

Granulocyte macrophage-colony stimulating factor (GM-CSF) has immuno-stimulatory effects. We hypothesized that GM-CSF plays an important role both in lipopolysaccharide (LPS)- and hemorrhage-induced acute lung injury (ALI). We also postulated that...

Enhancement of radiosensitivity by combined ceramide and dimethylsphingosine treatment in lung cancer cells

Park HW, Song JY, Kim KS, Han Y, Kim CW, Yi SY, Yun YS

  • KMID: 1123762
  • Exp Mol Med.
  • 2004 Oct;36(5):411-419.
Ceramide generated from sphingomyelin in response to ionizing radiation has been implicated as a second messenger to induce cellular proapoptotic signals. Both ceramide and its metabolic inhibitor, N, N-dimethyl-D-erythro-sphingosine (DMS),...
