The present study investigated the effects of valerian methanolic extract and valerenic acid on expression LL-37 gene protein in A549 MRC5 line cells. After preparing Valerian seeds, sowing them March 2020, harvesting rhizome October was prepared from by maceration method. content determined using high performance liquid chromatography (HPLC). Two cell lines (A549 MRC-5) were used to extract, M...

Worldwide, lung cancer is the most common form of cancer. Saffron has been used in folk medicine for centuries. We investigated the potential of saffron to induce cytotoxic and apoptotic effects in lung cancer cells (A549). We also examined the caspase-dependent pathways activation of saffron-induced apoptosis against the A549 cells. A549 cells were incubated with different concentrations of sa...

In this study, we evaluated the role of apurinic/apyrimidinic endonuclease1/redox factor-1 (Ref-1) on the tumor necrosis factor-alpha (TNF-alpha) induced cyclooxygenase-2 (COX-2) expression using A549 lung adenocarcinoma cells. TNF-alpha induced the expression of COX-2 in A549 cells, but did not induce BEAS-2B expression. The expression of COX-2 in A549 cells was TNF-alpha dose-dependent (5~100...

Metformin (Met) has been widely used in hypoglycemic therapy, and it is also able to reduce the incidence of tumors and tumor-related mortality. The present study investigated whether Met could inhibit the proliferation of lung cancer cells and enhance the sensitivity of a cisplatin-resistant lung cancer A549/CDDP cell line to cisplatin. It was found that Met treatment inhibited the proliferati...

Hinokitiol, a natural monoterpenoid from the heartwood of Calocedrus formosana, has been reported to have anticancer effects against various cancer cell lines. However, the detailed molecular mechanisms and the inhibiting roles of hinokitiol on adenocarcinoma A549 cells remain to be fully elucidated. Thus, the current study was designed to evaluate the effect of hinokitiol on the migration of h...

Background: Lung cancer is the second most common worldwide. Eucalyptus plant extract has been shown to have anti-neoplastic effects. We investigated antitumor effect of ethanolic and aqueous extracts camaldulensis collected at different altitudes on A549. In addition, we evaluated additive its combination with low-dose cisplatin (CDDP). Methods: Qualitative quantitative analyses secondary meta...

To investigate the role of circ_0084927 in lung cancer cell sensitivity to cisplatin. Half-maximal inhibitory concentration value cisplatin was detected by counting kit-8. and microRNA-634 expression were determined reverse transcription quantitative polymerase chain reaction. Cell kit-8, scratch healing, colony formation as well Transwell experiments used for analyzing viability, healing rate,...

OBJECTIVE To evaluate the cytotoxic effect of a hexane extract of Cassia alata leaves in A549 lung cancer cells. METHOD Parental A549 lung cancer cells were exposed to various concentrations (100-180 microg/ml) of Cassia alata leaf extract for 24 hours. Following treatment, the cells were evaluated using the 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay to determi...

Bufalin is a class of toxic steroids which could induce the differentiation and apoptosis of leukemia cells, and induce the apoptosis of gastric, colon and breast cancer cells. However, the anti-tumor effects of bufalin have not been demonstrated in lung cancer. In this study we used A549 human lung adenocarcinoma epithelial cell line as the experimental model to evaluate the potential of bufal...

BACKGROUND Our previous genome-wide gene expression analysis revealed that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) death receptors 4 (DR4) and 5 (DR5) are markedly upregulated by the ethanolic extract of D. sohia seeds (EEDS) in A549 TRAIL-refractory cancer cells. In the present study, we investigated whether the EEDS-mediated upregulation of TRAIL death receptors was as...
