LY2109761 treatment induces a dose-dependent low-anchorage growth inhibition of L3.6pl/GLT cells, leading to ~33% or 73% inhibition at 2 μM and 20 μM, respectively, which can be strongly enhanced when combined with gemcitabine in combination index value of 0.36581. Blocking TβRI/II kinase activity with LY2109761 (5 μM) completely suppresses both the basal and TGF-β1-stimulated migration and invasion of L3.6pl/GLT cells, significantly enhances the detachment-induced apoptosis by 26% at 8 hours treatment, and completely suppresses TGF-β–induced Smad2 phosphorylation. [1] LY2109761 treatment at 1 nM is sufficient to significantly block the migration and invasion but not adhesion of hepatocellular carcinoma cells by increasing E-cadherin expression. [2] LY2109761 pretreatment enhances radiosensitivity of glioblastoma cells via TGF-β signaling blockage. LY2109761 (10 μM) reduces the self-renewal and proliferation of GBM-derived cancer stem–like cells (CSLC), which can be significantly enhanced when combined with radiation. [3]

In vivo Administration of LY2109761 (50 mg/kg) alone or in combination with gemcitabine (25 mg/kg) significantly reduces the tumor volume by ~70% and ~90%, respectively, prolongs the survival with the median survival duration of 45.0 days and 77.5 days, respectively, and reduces spontaneous abdominal metastases in the L3.6pl/GLT Xenograft mice model. [1] In consistent with the in vitro effect, administration of LY2109761 alone or in combination with radiation, markedly inhibits tumor growth in the orthotopical CSLC glioblastoma model by 43.4% and 76.3%, respectively, decreases tumor invasion and tumor microvessel density, and significantly enhances radiation-induced tumor growth delay in the U87MG xenograft mice model. [3]

Protocol (from reference)

Cell Research:[1]
  • Cell lines: Colo357FG/GLT, and Colo357L3.6pl/GLT
  • Concentrations: Dissolved in DMSO, final concentrations ~10 μM
  • Incubation Time: 48 hours
  • Method: Cells are exposed to increasing doses of LY2109761 (~10 μM) for 48 hours. The medium containing drugs is removed, the cells are washed twice with PBS, and fresh medium is added. After 5 days of incubation, the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay is used to obtain relative variable cell numbers.
  • (Only for Reference)
Animal Research:[1]
  • Animal Models: Athymic nude mice with orthotopic implantation of L3.6pl/GLT cells
  • Dosages: 50 mg/kg
  • Administration: Twice a day p.o.
  • (Only for Reference)
