  • Conditional description: MDA-MB-231 D3H2LN-Luc cell line that expresses tetracycline (Tet)-regulated transactivator Tet-On 3G regulated expression of ROCK2. Therefore ROCK2 expression is induced in the presence of doxycycline.
  • Description: This cell line has been engineered to enable tetracycline inducible expression of the kinase ROCK2. ROCK2 is a serine/threonine kinase which acts as a key regulator of the actin-myosin cytoskeleton and cell polarity. ROCK2 promotes contractile force generation and therefore is a modulator of cell motility and tumour cell 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.
