Description:
Keywords: Breast Cancer Stem Cells

Assay Overview: The objective of the experiments in this proposal is to identify chemical compounds that can selectively kill breast cancer stem cells (CSCs). The HMLE cell line suppressing TWIST expression (HMLE_shTWIST), which is a stable cell line that has been induced into epithelial-to-mesenchymal transdifferentiation (EMT). This cell line was used to represent a uniform population of CSCs and act as a confirmation to the HMLE_shECad cell line (See AID 2721). Compounds are added to cells and are incubated ~72 hours. Cell viability was measured using CellTiter-Glo and luminescence is measured. The chemical compounds that selectively kill CSCs would be promising new drug candidates for anti-cancer therapy and would also serve as useful probes to study CSC biology, which are currently lacking.

Expected Outcome: Compounds significantly suppressing luminescence, and therefore toxic to HMLE_shTWIST will be identified as hits in the screen.

HMLE_shTwist were previously described in Gupta PB, Onder TT, Jiang G, Tao K, Kuperwasser C, Weinberg RA, Lander ES. Identification of selective inhibitors of cancer stem cells by high-throughput screening. Cell. 2009 Aug 21;138(4):645-59. Epub 2009 Aug 13. PMID: 19682730).

Cells were propagated in Propagation media. For experiments, cells were plated using Screening media.

Cells were seeded in 40 ul of Screening medium containing 1000 cells per well into white 384-well opaque-bottom plates (Nunc, Rochester, NY) using an automated plate filler (Bio-Tek uFiller; Winsooki, VT). At 24 hr, 100 nL of compound solutions were pin transferred from stock 384-well plates into the 384-well assay plates containing cells, resulting in 0.010-032 uM final concentration. Cells were incubated for 72 hrs.

HMLE_shEcad lines were each screened in two replicates. Two kinds of negative control wells were employed for normalization: multiple DMSO-only control wells were present on each compound assay plate screened. CellTiter-Glo Reagent (Promega) was added 3 days after compound addition (20 ul/well). Luminescence signal was measured with an automated plate reader (Perkin-Elmer Envision 1).
