Article Abstract
Objective: To investigate the effects of Cordycepin on proliferation and apoptosis of A549 cells, and its possible mechanism of action.
Methods: Human lung cancer cell line A549 cells were treated with different concentrations of Cordycepin for 24 h. MTS assay was used to detect cell proliferation. Hoechst 33258 staining and Annexin V/PI flow cytometry were used to determine the apoptosis of A549 cells. The protein expression of nuclear factor-κB p65 (NF-κB p65), BAX, BCL-2 and cleaved Caspase-3 was determined by Western blot.
Results: In a dose dependent way, Cordycepin inhibited the proliferation and promoted the apoptosis of A549 cells, increased the expression of BAX and cleaved Caspase-3, while decreased the expression of BCL-2. The Western blot results showed, Cordycepin dose-dependently inhibited the entry of NF-κB p65 to nuclear in A59 cells.
Conclusion: Cordycepin can inhibit the proliferation and induct the apoptosis of A549 cells, the mechanism of action is achieved by inhibiting the NF-κB pathway.

Non-small cell lung cancer (NSCLC) is an aggressive malignancy with a poor prognosis. Abnormal expression of focal adhesion kinase (FAK) is closely linked to NSCLC progression, highlighting the need for effective FAK inhibitors in NSCLC treatment. In this study we conducted high-throughput virtual screening combined with cellular assays to identify potential FAK inhibitors for NSCLC treatment.

Coal worker pneumoconiosis is an occupational pulmonary fibrosis (PF) caused by prolonged exposure to respirable coal dust (CD), with limited therapeutic options. Here, we explored the antifibrotic effects of metformin (Met) in CD-nanoparticle (CD-NP)-induced PF, focusing on its preventive and therapeutic potential. In vivo, Met was administered at different doses (low: 31.

A series of novel matrine derivatives incorporating thiosemicarbazide moieties was designed and synthesized. The in vitro cytotoxicity of these compounds was evaluated against four human cancer cell lines: MCF-7, HepG2, SGC-7901, and A549. Results demonstrated that their cytotoxic activity was significantly higher than that of matrine.

Objectives: To investigate the antitumor effects of aucubin (AC) in non-small cell lung cancer (NSCLC) and uncover its plausible mechanism against lung cancer stem-like cells (LCSCs).
Methods: In vitro experiments included MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a reagent commonly used for cell viability assay) and colony formation assays to assess anti-proliferative effects on A549 and NCI-H1975 lung cancer cell lines, wound healing and Transwell invasion assays to evaluate inhibition of cell migration and invasion, tumorsphere-formation experiments to detect changes in NSCLC cell stemness, as well as Western blot and quantitative reverse transcription polymerase chain reaction (qRT-PCR) analyses to measure the expression of LCSC markers (CD44, CD133, Oct4, and Nanog). In vivo experiments were conducted to observe the impact of AC on NSCLC metastasis and mouse survival rates.
