A549 Cells: A Well-Characterized Lung Carcinoma Cell Line Utilized for a Variety of Scientific Studies, including Adenovirus Pro

Posted May 14 2009 5:00pm

Description of Invention:
Scientists at the National Institutes of Health have developed a cell line designated A549 that was derived from explanted cultures of human lung cancer tissue. The A549 cell line has been tested under the guidance of the United States Food and Drug Administration (FDA) so, under current Good Manufacturing Practices (GMP), these cells may be suitable for use in manufacturing constructs for use in clinical trials. The A549 cell line has also been found to be suitable for adenovirus production, most notably replicating adenovirus constructs that do not require complementation by the viral oncogene, early region 1A (E1A), which is responsible for viral gene transcription. This cell line is further utilized as a negative control in assays to measure the replication of adenoviruses that lack E1A and as a target cell line to detect replication competent adenoviruses (RCA). A549 cells have been well characterized through their use in a wide variety of molecular studies, such as anti-tumor drug permeability and efficacy analysis, infection assays, respiratory immunotoxicity tests, cell senescence studies, and cytokine expression profiling. These cells can also be utilized to study a variety of molecular characteristics for human tumors in culture.

Applications:
  • Cell bank tested under cGMP-compliance regulations and used to produce adenoviruses for use in clinical trials
  • Research tool to analyze the efficacy of potential anti-cancer agents to devise better cancer treatments for malignancies, such as non-small cell lung cancer (NSCLC)
  • Research tool to study the infectivity of viruses that cause asthma in order to develop better asthma treatments
  • Standard research tool to analyze a variety of molecular biology procedures, for example, cell senescence, cytokine induction, protein expression, apoptosis, and receptor-ligand interactions


Advantages:
  • A549 cells are a well-characterized standard among the human lung carcinoma/alveolar cell lines used in molecular biology.
  • The A549 cells stored at the NIH were tested under the guidance of the FDA’s cGMP regulations.
  • The A549 cells stored at the NIH may be suitable for producing adenoviruses that can be used in clinical trials and analyzing adenoviral-based therapies and vaccine strategies.
