  • Description: Abstract 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 the genetic events related to its development. Herein, we have identified the presence of homozygous deletions of the candidate histone acetyltransferase KAT6B, and the loss of the corresponding transcript, in SCLC cell lines and primary tumors. Furthermore, we show, in vitro and in vivo, that the depletion of KAT6B expression enhances cancer growth, while its restoration induces tumor suppressor–like features. Most importantly, we demonstrate that KAT6B exerts its tumor-inhibitory role through a newly defined type of histone H3 Lys23 acetyltransferase activity. Cancer Res; 75(18); 3936–45. ©2015 AACR.
