Figure Lengend Snippet: Intracellular ROS production in LNCaP cells after treatment with B. natalensis hydroethanolic leaf extract (BNHLE). LNCaP cells (10,000 cells/well) were treated for 45 min with 100 µL of 20 µM of DCFH-DA diluted in culture medium containing 2% FBS. Thereafter, these cells were exposed for 24 h to BNHLE (100, and 200 µg/mL), and hydrogen peroxide (H 2 O 2 , 50 µM) or DMSO (0.5%) used as negative control (Ctrl). Images were captured using a Flexacam C1 camera (Leica Microsystems GmbH, Wetzlar, Germany) connected to a fluorescence microscope (Leica Microsystems GmbH, Wetzlar, Germany) using an excitation/emission filter (480/535 nm) on 20× objective ( A ). The cell fluorescence was measured at the wavelengths of 485 nm (excitation) and 535 nm (emission) on a SpectraMax iD3 multi-mode microplate reader (Molecular Devices, San Jose, CA, USA), and intracellular ROS levels were expressed as percentage of negative control cells ( B ). One-way ANOVA combined with Dunnett or Student–Newman–Keuls’s tests were used for data analysis. * means statistically different ( p < 0.05) vs. Ctrl.
Article Snippet: Eight cancer cell lines, namely, human breast carcinoma cells (MCF-7), 4T1 mammary carcinoma cells, human colorectal carcinoma cells (Caco-2), human cervical carcinoma cells (HeLa), human lung carcinoma cells (A549), human hepatocellular carcinoma (HepG2), DU145 (androgen-insensitive), and LNCaP (androgen-sensitive) human prostate cancer cell lines, were obtained from the American Type Culture Collection (ATCC) (Rockville, MD, USA) or the European Collection of Authenticated Cell Cultures (ECACC) (Porton Down, UK).
