Figure Lengend Snippet: Antitumor activity of fractions from BamazV separated by molecular weight. Fractions were separated through an ultrafiltration process using a regenerated cellulose membrane (Amicon ® Ultra-15 Centrifugal Filter Ultracel ® 10K and 3K). MCF10A, SKBR3, MCF7, and MDA-MB-231 cell lines (seeded at 1 × 10 5 cells/well) were treated and incubated with BamazV fractions (<3 kDa, 3–10 kDa, and >10 kDa) at concentrations of 0.2, 1, 5, and 25 μg/mL for 24 h. Then, cell viability was assessed using the MTT assay. Data represent the mean ± SD of triplicate measurements from 3 independent experiments. NC - negative control (only culture medium). PC - positive control (30% DMSO). Statistical significance: group vs. NC, * p < 0.05.
Article Snippet: The breast tumor cell lines SKBr3, MCF-7, and MDA-MB-231, as well as the control breast epithelial cell line MCF10A, were obtained from the American Type Culture Collection (ATCC, Manassas, VA) and maintained in RPMI 1640 (Roswell Park Memorial Institute) supplemented with 10% FBS and 1% penicillin/streptomycin at 37 C, 5% CO 2 .
