  • Cancer type: Triple negative breast cancer (TNBC)
  • Disease: Cancer
  • Description: This cell line has been engineered to enable tetracycline inducible expression of the kinase MRCK?. MRCK? is a myotonic dystrophy kinase-related CDC42-binding kinase involved in regulating actin-myosin contractility and implicated in cancer metastasis. MRCK?, in conjunction with MRCKa, ROCK1 and ROCK2 kinases, initiates signalling events that lead to contractile force generation which powers cancer cell motility and invasion. The cell line is a derivative of a human breast cancer cell line shown to reliably metastasize to clinically relevant sites (the lungs and lymph nodes) when implanted orthotopically in mice (i.e. when implanted in the breast pad of mice). The cell line expresses luciferase enabling detection of the location of the cells using bioluminescent imaging. Useful for the study of breast cancer cell cytoskeleton reorganisation and cell migration. This cell line is derived from a triple negative breast cancer (TNBC) meaning it does not express oestrogen, progesterone or HER2 receptors.
