General description

The TR146 cells are appropriate for drug transport studies and they mimic normal human buccal epithelium. It serves as an oral mucosa model for barrier property studies with various molecules including tight junction proteins, aquaporins and epithelial-mesenchymal transition (EMT) markers.

Cell Line Origin

Human squamous cell carcinoma

Cell Line Description

TR146 was derived from the neck node of a 67 year-old female (primary tumour was sited in buccal mucosa). The patient had had previous radiotherapy (6,000 rads) and neck dissection. TR146 is tumourigenic in female (nu/nu) mice leading to the production of rapidly progressing tumours. Histology: well-differentiated keratinizing squamous cell carcinoma.


TR146 cell line human has been used:
  • in cytotoxicity studies with an antibacterial compound, metronidazole
  • in viability and metabolic studies post blue laser light exposure,
  • as an oral epithelium-resembling cell line model for in vitro C. albicans infection studies
  • in barrier function studies using transepithelial electrical resistance (TEER)
  • for the transport studies with C-reactive protein (CRP)

Parameters that influence the precipitation of the beta-cyclodextrin (beta-CD) inclusion complexes of the antimycotics miconazole and econazole were investigated. The mechanistic reason for the superior antimycotic activity of the miconazole inclusion complex was studied. The toxicity of the complex was...
