Osteosarcoma (OS), a malignant bone tumor with limited treatment options, exhibits low sensitivity to immune checkpoint therapy (ICT). Through genomics and transcriptomics analyses, we have identified a subgroup of OS with methylthioadenosine phosphorylase (MTAP) deletion, which contributes to ICT r...

Glioblastoma (GBM) is a lethal brain tumor with remarkable intra-tumoral heterogeneity and therapeutic resistance which is linked to glioma stem cell (GSC). GSC contains unstable genome and elevated genomic instability could impair GSC self-renewal and tumorigenicity. In addition, GSC displays great...

Both immunodeficient and wild type NOD mice exhibit defects in control of early T-cell development in the thymus. We show that Rag1-deficient NOD mice fail to enforce both the b-selection checkpoint and an earlier T-cell commitment checkpoint, based on genome-wide genetic and transcriptome analyses....

The FA/BRCA pathway repairs DNA interstrand crosslinks. Mutations in this pathway cause Fanconi anemia (FA), a chromosome instability syndrome with bone marrow failure and cancer predisposition. Upon DNA damage, normal and FA cells inhibit the cell cycle progression, until the G2/M checkpoint is tur...
The elucidation of therapy-induced changes to the class I major histocompatibility complex (MHC-I)-bound tumor antigens is crucial for understanding immune-mediated tumor eradication and identifying potential targets for peptide vaccines to enhance the efficacy of immunotherapies. Here, we investiga...

Hypoxia promotes an aggressive tumor phenotype with increased genomic instability, partially due to downregulation of DNA repair pathways. However, in addition to DNA repair, genome stability is also controlled by cell cycle checkpoints. An important issue is therefore whether hypoxia also can alter...
