EEF1A2 Interacts with HSP90AB1 to Promote Lung Adenocarcinoma Metastasis via Enhancing TGF-β/SMAD Signaling

Scientists report that eukaryotic protein translation elongation factor 1α2 (EEF1A2) mediates the epithelial–mesenchymal transformation, to promote the metastasis of lung adenocarcinoma cells in vitro and in vivo.

ACPA Decreases Non-Small Cell Lung Cancer Line Growth through Akt/PI3K and JNK Pathways In Vitro

Investigators confirmed that CB1 receptor (CB1R) was expressed in non-small cell lung cancer cells in this study. Arachidonoylcyclopropylamide (ACPA) as a synthetic, CB1R-specific ligand decreased proliferation rate in NSCLC cells by WST-1 analysis and real-time proliferation assay.

Metabolism and Pharmacokinetics of a Novel Polyphenol Fatty Acid Ester Phloridzin Docosahexaenoate in Balb/C Female Mice

Researchers report metabolites and pharmacokinetic parameters of phloridzin docosahexaenoate (PZ-DHA), determined using ultra-high-performance liquid chromatography-electrospray ionization tandem mass spectrometry. PZ-DHA was taken-up by human and mouse mammary carcinoma and human non-malignant mammary epithelial cells in cellular uptake assays.
