TRIB2 confers resistance to anti-cancer therapy by activating the serine/threon...
Hill, Richard; Madureira, Patricia; Ferreira, Bibiana; Baptista, Inês; Machado, S.; Colaco, Laura; dos Santos, Marta; Liu, Ningshu; Dopazo, AnaIntrinsic and acquired resistance to chemotherapy is the fundamental reason for treatment failure for many cancer patients. The identification of molecular mechanisms involved in drug resistance or sensitization is imperative. Here we report that tribbles homologue 2 (TRIB2) ablates forkhead box O activation and disrupts the p53/MDM2 regulatory axis, conferring resistance to various chemotherapeutics. TRIB2 sup...
TRIB2 as a biomarker for diagnosis and progression of melanoma
Hill, Richard; Kalathur, Ravi Kiran Reddy; Colaco, Laura; Brandao, Ricardo; Ugurel, Selma; Futschik, Matthias; Link, WolfgangMalignant melanoma is the most deadly form of skin cancer. There is a critical need to identify the patients that could be successfully treated by surgery alone and those that require adjuvant treatment. In this study, we demonstrate that the expression of tribbles2 (TRIB2) strongly correlates with both the presence and progression of melanocyte-derived malignancies. We examined the expression of TRIB2 in addit...
