Metastatic competence can emerge with selection of pre-existing oncogenic alleles without a need of new mutations

Several experimental models faithfully recapitulate many important facets of human metastatic disease. Here we have performed whole exome sequencing in five widely used experimental metastasis models that were independently derived through in vivo sele...

KAT6B is a tumor suppressor histone H3 lysine 23 acetyltransferase undergoing genomic loss in small cell lung cancer

Recent efforts to sequence human cancer genomes have highlighted that point mutations in genes involved in the epigenetic setting occur in tumor cells. Small cell lung cancer (SCLC) is an aggressive tumor with poor prognosis where little is known about...

Maspin Expression in Prostate Tumor Cells Averts Stemness and Stratifies Drug Sensitivity

Future curative cancer chemotherapies have to overcome tumor cell heterogeneity and plasticity. To test the hypothesis that the tumor suppressor maspin may reduce microenvironment-dependent prostate tumor cell plasticity and thereby modulate drug sensi...

IL-17 promotes mammary tumor progression by changing the behavior of tumor cells and eliciting tumorigenic neutrophils recruitment

The aggressiveness of invasive ductal carcinoma (IDC) of the breast is associated with increased IL-17 levels. Studying the role of IL-17 in invasive breast tumor pathogenesis, we found that metastatic primary tumor-infiltrating T lymphocytes produced ...

A threshold level of intratumor CD8+ T cell PD1 expression dictates therapeutic response to anti-PD1

Despite successes, thus far a significant proportion of the patients treated with anti-PD1 antibodies have failed to respond. We use mouse tumor models of anti-PD1 sensitivity and resistance, and flow cytometry to assess tumor infiltrating immune cells...
