Figure Lengend Snippet: Cell Viability of gold anticancer agents, gold-loaded peptide nanofilaments ( PD+1 , PD+2 , AD+1 , AD+2 ), and peptides ( PD , AD ) in three human cell lines. Caki-1 (renal cancer), MDA-MB-231 (Triple Negative Breast Cancer), and IMR-90 (lung fibroblasts) incubated with drug-loaded peptide for 72 h. A) Compound 1 , B) Compound 2 . (* represents P <0.05, ** represents P <0.01, *** represents P <0.001).

Article Snippet: Human breast adenocarcinoma line MDA-MB-231 and human lung fibroblast line IMR-90 were obtained from the American Type Culture Collection (ATCC; Manassas, Virginia, USA) and cultured with Dulbecco’s modified Eagle’s medium (DMEM; Fisher Scientific) containing 10 % fetal bovine serum, certified, heat inactivated, US origin (FBS; Fisher Scientific), 1 % minimum essential media (MEM) nonessential amino acids (NEAA; Fisher Scientific), and 1 % penicillin–streptomycin (PenStrep; Fisher Scientific).

Techniques: Incubation

Article Title: Induction of AMPK activation by N , N’- diarylurea FND-4b decreases growth and increases apoptosis in triple negative and estrogen-receptor positive breast cancers

doi: 10.1371/journal.pone.0209392

Figure Lengend Snippet: Equal numbers of MCF-7, T-47D, MDA-MB-231, HCC-1806 or breast cancer stem cells were treated with fresh medium that contained different FND-4b concentrations (0, 1, 2.5, 5, 10, and 20 μM) for 24 h. Western blot analysis was then performed for phosphorylated and total forms of AMPKα, ACC, and S6 as well as cyclin D1 and cleaved PARP. Beta-actin was used as the loading control. Treatment of the HCC-1806 cell line was repeated to confirm the spike in AMPKα activation at the 5 μM dosage with subsequent decreases at higher concentrations.

doi: 10.1371/journal.pone.0209392

Figure Lengend Snippet: (A) Equal numbers of MCF-7, T-47D, MDA-MB-231, HCC-1806, or breast cancer stem cells were grown in medium containing 0 or 5 μM FND-4b for 72 h followed by cell counting. (B) The same procedure described in (A) was followed with the exception of growing cells in medium containing 0 or 1 mM AICAR instead. (C) MCF-7, T-47D, MDA-MB-231, and HCC-1806 cells were grown in medium containing different concentrations of FND-4b (0, 2.5, 5, 10, and 20 μM) for 72 h before SRB growth assays were performed. Data are presented as mean ± SD from experiments performed in triplicate (cell counting) or sextuplicate (SRB assays) and are representative of three independent experiments. * indicates p-value < 0.01.
