The results indicated that niclosamide in combination with DDP demonstrated a synergistic effect in A549/DDP cells and directly induced apoptosis, which may be associated with caspase‑3 activation.
As oxidative stress may drive tumor progression, we further demonstrate that nostoglycan can suppress the proliferation of several types of tumor cells and induce apoptosis of human lung adenocarcinoma A549 cells via caspase-3 activation.
Ruthenium(II)-Polypyridyl Compounds with π-Extended Nitrogen Donor Ligands Induce Apoptosis in Human Lung Adenocarcinoma (A549) Cells by Triggering Caspase-3/7 Pathway.
Overall, these findings suggest that Livin has the potential to become a biomarker for predicting the prognosis of lung adenocarcinoma and may provide a promising strategy for assisting chemotherapy of lung adenocarcinoma through the miR-198/Livin/caspase-3 regulatory network.
MiRNAs are characteristically expressed in tumor-initiating Sca-1(+) CD34(+) cells of lung adenocarcinoma, and may play important roles during the carcinogenesis of lung adenocarcinoma.
Double staining of LRPPRC with active caspase-3 in clinical samples of lung adenocarcinoma revealed that apoptotic cells were hardly observed in LRPPRC-expressing tumours.
Expression of miR-210 in lung adenocarcinoma A549 cells caused an alteration of cell viability associated with induction of caspase-3/7 activity. miR-210 induced a loss of mitochondrial membrane potential and the apparition of an aberrant mitochondrial phenotype.
In present report, we used fluorescence confocal imaging and fluorescence resonance energy transfer (FRET) techniques based on green fluorescent proteins (GFPs) to monitor the spatio-temporal dynamics of Bid translocation and caspase-3 activation in real time in living human lung adenocarcinoma (ASTC-a-1) cells under neutral (pH 7.4) and alkaline (pH 8.0) conditions.
