The catalytic activity of human AURORA-A kinase (AURKA) regulates mitotic progression, and its frequent overexpression in major forms of epithelial cancer is associated with aneuploidy and carcinogenesis. Here, we report an unexpected, kinase-independent function for AURKA in DNA replication initiation

The ChIP-exo assay precisely delineates protein-DNA crosslinking patterns by combining chromatin immunoprecipitation with 5' to 3' exonuclease digestion. Within a regulatory complex, the physical distance of a regulatory protein to DNA affects crosslinking efficiencies. Therefore, the spatial organization of a

Spindle assembly checkpoint governs proper chromosomal segregation during mitosis to ensure genomic stability. At the cellular level, this event is tightly regulated by UBE2C, an E2 ubiquitin-conjugating enzyme that donates ubiquitin to the anaphase-promoting complex/cyclosome. This, in turn, facilitates anaphase-onset

Cell metabolism, 30(3), 556-572 (2019-08-27)
Lipid metabolism is frequently perturbed in cancers, but the underlying mechanism is unclear. We present comprehensive evidence that oncogene MYC, in collaboration with transcription factor sterol-regulated element-binding protein (SREBP1), regulates lipogenesis to promote tumorigenesis. We used human and mouse tumor-derived

The lysine (K)-specific demethylase (LSD1) family of histone demethylases regulates chromatin structure and the transcriptional potential of genes. LSD1 is frequently deregulated in tumors, and depletion of LSD1 family members causes developmental defects. Here, we report that reductions in the

Dishevelled-1 (DVL-1) mediates Wnt signals critical for development and cellular homeostasis. DVL-1 is also linked with tumorigenesis, however its association with specific breast cancer (BC) subtypes and how it contributes to tumorigenicity remains poorly studied. Herein, using bioinformatics and genomics

Nature medicine, 24(10), 1599-1610 (2018-09-19)
Cancer cells rely on dysregulated gene expression. This establishes specific transcriptional addictions that may be therapeutically exploited. Yet, the mechanisms that are ultimately responsible for these addictions are poorly understood. Here, we investigated the transcriptional dependencies of transformed cells to
