Prinaberel (ERB-041) (0-60 µM; 24 hours) treatment of human SCC cells induces cell differentiation, cell cycle arrest and reduces colony formation.
Prinaberel shows a marked reduction in the expression of inflammation regulatory proteins such as p-NFκBp65, iNOS and COX-2 in A431 cells. Prinaberel diminishes phosphorylated-PI3K and -AKT, which is associated with the enhancement in E-cadherin expression and reduction in migration of A431 cells.
Prinaberel (0.01-10 µM) inhibits cell proliferation in a dose- and time-dependent manner.
Prinaberel (10 µM; 48 hours) promotes ovarian cancer (SKOV-3 cells) apoptosis.
Western Blot Analysis
| Cell Line: | A431 cells |
| Concentration: | 0, 20, 40 and 60 µM |
| Incubation Time: | 24 hours |
| Result: | Reduction in the expression of G1 cyclins (D1, D2 and D3) and CDK4. |
Cell Proliferation Assay
| Cell Line: | SKOV-3, A2780CP or OVCAR-3 cells |
| Concentration: | 0.01, 0.1 and 10 µM |
| Incubation Time: | 24-48 hours |
| Result: | Showed significantly inhibitory effect on cell proliferation. |
Prinaberel (2mg/mouse; topically; 30 min prior to UVB irradiation for 30 weeks) suppresses development of squamous cell carcinoma in SKH-1 hairless mice.
Prinaberel reduces proliferation and angiogenesis and induces apoptosis in UVB-induced skin tumors. Prinaberel suppresses pro-inflammatory signaling pathway in UVB-induced skin tumors. Prinaberel diminished tumor invasiveness via PI3K-AKT pathway and WNT signaling.
| Animal Model: | Six- to eight-weeks-old SKH-1 hairless female mice |
| Dosage: | 2 mg/mouse in 200µl ethanol |
| Administration: | Topically; 30 min prior to UVB (180mJ/cm2) irradiation for 30 weeks |
| Result: | Diminished UVB-induced skin tumor development in SKH-1 hairless mice. |
