Oncogenic Wnt/β-catenin activation promotes cancer development and drug resistance to cancer treatments. We recently revealed an underlying mechanism linking linear ubiquitination with Wnt/β-catenin activation upon genotoxic treatments. We showed that ABL1 (ABL proto-oncogene 1)-dependent phosphorylation of OTULIN (OTU deubiquitinase with linear linkage specificity) upon DNA damage drives β-catenin activation which promotes drug resistance in triple-negative breast cancer.
致癌性Wnt/β-连环蛋白激活促进癌症发展和对癌症治疗的耐药性。我们最近揭示了一种在基因毒性治疗后将线性泛素化与Wnt/β-连环蛋白激活联系起来的潜在机制。我们发现,DNA损伤后,ABL1(ABL原癌基因1)依赖的OTULIN(具有线性连接特异性的OTU去泛素酶)磷酸化驱动β-连环蛋白激活,从而促进三阴性乳腺癌的耐药性。
