TMPRSS2 Proteolytic Cascade in Prostate Cancer

Dysregulation of androgen signaling and pericellular proteolysis is necessary for prostate cancer progression, but the links between them are still obscure. In this study, we show how the membrane-anchored serine protease TMPRSS2 stimulates a proteolyt...

Androgen-induced TMPRSS2 activates matriptase and promotes extracellular matrix degradation, prostate cancer cell invasion, tumor growth and metastasis

Dysregulation of androgen signaling and pericellular proteolysis are necessary for prostate cancer (PCa) progression but the links between them are still obscure. In this study, we show how the membrane-anchored serine protease TMPRSS2 stimulates a pr...

Bypass of BRAFV600E Growth Arrest in Lung Tumorigenesis

Lung carcinogenesis is a multistep process in which normal lung epithelial cells are converted to cancer cells through the sequential acquisition of multiple genetic or epigenetic events. Despite the utility of current genetically engineered mouse (GEM...

TP53 Silencing Bypasses Growth Arrest of BRAFV600E-Induced Lung Tumor Cells In a Two-Switch Model of Lung Tumorigenesis

Lung carcinogenesis is a multistep process in which normal lung epithelial cells are converted to cancer cells through the sequential acquisition of multiple genetic or epigenetic events. Despite the utility of current genetically engineered mouse (GEM...

Therapy-Caused Tumor Progression

Tumor resistance to cytotoxic drugs is one of the main obstacles to successful cancer therapy. Emerging evidence suggests that chemoresistance is promoted by substances released from dead and damaged cells that activate the host repair program orchest...
