| Open AccessMYC paralog-dependent apoptotic priming orchestrates a spectrum of vulnerabilities in small cell lung cancer
The expression of oncogenic MYC paralogs in small cell lung cancer is mutually exclusive. In this study, the authors show that MYC, but not MYCN or MYCL, represses BCL2, resulting in cells that are uniquely sensitive to apoptosis, and find that CHK1 and AURKA inhibitors may be useful for treating these cancers.

| Open AccessCo-activation of super-enhancer-driven CCAT1 by TP63 and SOX2 promotes squamous cancer progression
Master regulator transcription factors TP63 and SOX2 have been reported to overlap in genomic occupancy in squamous cell carcinomas (SCCs). Here, the authors demonstrate that TP63 and SOX2 promote co-operatively long non-coding RNA CCAT1 expression through activating its super-enhancer, and CCAT1 forms a complex with TP63 and SOX2, which regulates EGFR super-enhancers and enhances both the MEK/ERK1/2 and PI3K/AKT signaling pathways in SCC.
