Clinical Data 58 years

In lung cancer, Vimentin intermediate filament (IF) proteins have been implicated in many aspects of cancer initiation and progression, including tumorigenesis, epithelial-to-mesenchymal transition (EMT/MET), and the metastatic spread of cancer. Vimentin expression is generally upregulated when the cell is in the mesenchymal relative to the epithelial status. Here, we created a Vim-RFP reporter cell line (CCL-185EMT) using the CRISPR/Cas9 gene editing platform and the parental A549 (CCL-185) non-small cell lung cancer (NSCLC) cell line (a gold standard for studying EMT in cancer metastasis within the lung cancer research community). The created CCL-185EMT cell line habors a C-terminal red fluorescent protein (RFP) tag on the vimentin gene. This will enable the tracking of the EMT status of cells in vitro by monitoring RFP expression. The integrity of the Vim RFP knock-in has been verified at the genomic, mRNA and protein level for sequence and expression. Functional evaluation of CCL-185EMT shows sensitivity to anti-EMT drugs PP1 and A83-1. This provides the foundation for the high throughput (HTS) identification of new anti-EMT drugs for metastatic NSCLC therapy. The A549 Vim RFP reporter cell line provides a visualizable, convenient and sensitive platform for research on the mechanisms of metastasis in vitro and the development of new antitumor drugs for metastatic NSCLC.

Complete Growth Medium The base medium for this cell line is F-12K Medium (ATCC 30-2004). To make the complete medium add the following to the base medium:
  • Fetal Bovine Serum (FBS; ATCC 30-2020) for a final concentration of 10%
Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning® T-75 flasks (catalog #430641) are recommended for subculturing this product.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
  3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
    Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
  4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
    Cultures can be established between 2 x 103 and 1 x 104 viable cells/cm2. Do not exceed 7 x 10 4 cells/cm2.
  6. Incubate cultures at 37°C.
Interval: Maintain cultures at a cell concentration between 6 X 103 and 6 X 104 cell/cm2.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:8 is recommended
Medium Renewal: 2 to 3 times per week
