Analysis of lymphoma cells isolated from Eµ-myc mice deficient in H3K9 histone methyltransferase Suv39h1 and treated in vitro with anticancer drug ADR. ADR induces therapy-induced senescence (TIS) in Suv39h1-proficient lymphomas. Results provide insight into the impact of Suv39h1 on TIS induction.

(Submitter supplied) Oncogene-induced senescence (OIS), a terminal cell cycle block countering (pre)neoplastic lesions, is characterised on the molecular level by trimethylated histone H3 lysine 9 (h3K9me3), a transcriptionally repressive chromatin mark linked to silencing of S-phase-promoting genes. Whether H3K9-governed chromatin remodelling influences anticancer treatment-induced senescence (TIS) and whether functional control of this mark impacts on treatment outcome is not known. more...

(Submitter supplied) Treatment induced senescence (TIS) is a terminal cell cycle arrest program, increasingly recognized as a tumor suppressor mechanism complementing apoptosis in response to standard chemotherapy regimens. In particular cells with blocked apoptotic pathways rely on senescence as the only remaining failsafe mechanism to keep the neoplastic growth in check. However, little is known about biological properties, long-term fate of senescent tumor cells and their impact on the microenvironment. more...

(Submitter supplied) Cellular dormancy and heterogeneous cell cycle lengths provide important explanations for treatment failure following adjuvant therapy with S-phase cytotoxics in colorectal cancer (CRC) yet the molecular control of the dormant versus cycling state remains unknown. In CRCs dormant cells are found to be highly clonogenic and resistant to chemotherapies. We sought to understand the molecular features of dormant CRC cells to facilitate rationale identification of compounds to target both dormant and cycling tumour cells.

(Submitter supplied) Glioblastoma (GBM) is a lethal brain cancer composed of heterogeneous cellular populations including glioma stem cells (GSCs) and their progeny differentiated non-stem glioma cells (NSGCs). Although accumulating evidence points out the significance of GSCs for tumour initiation and propagation, the roles of NSGCs remain elusive. Here we demonstrate that, when patient-derived GSCs in GBM tumours undergo differentiation with diminished telomerase activity and shortened telomeres, they subsequently become senescent phenotype, thereby secreting angiogenesis-related proteins, including vascular endothelial growth factors. more...

(Submitter supplied) Acetylation of histones by lysine acetyltransferases (KATs) is essential for chromatin organization and function. The MYST family of KATs (KAT5-8) includes the oncogenes KAT6A (MOZ) and KAT6B (MORF/QKF). KAT6A has essential roles in normal hematopoietic stem cells and is the target of recurrent chromosomal translocations, causing acute myeloid leukemia. Similarly, chromosomal translocations in KAT6B have been identified in diverse cancers. more...

The MYST family of KATs (KAT5-8) includes the oncogenes KAT6A (MOZ) and KAT6B (MORF/QKF). KAT6A has key roles in promoting cell proliferation through transcriptional activation of negative regulators of the Cdkn2a locus, which encode the tumor suppressors INK4A and ARF. We produced a series of highly potent, selective inhibitors of KAT6A/B including WM-8014 and WM-1119. more...

KAT6A has key roles in promoting cell proliferation through transcriptional activation of negative regulators of the Cdkn2a locus, which encode the tumor suppressors INK4A and ARF. To examine the loss of KAT6A function, mouse embryonic fibroblasts (MEFs) were isolated from E13.5 Kat6a+/+ and Kat6a–/– embryos and RNA-seq profiling was performed.

(Submitter supplied) Melanocytes within benign human nevi are the paradigm for tumor suppressive senescent cells in a pre-malignant neoplasm. These cells typically contain mutations in either the BRAF or N-RAS oncogene and express markers of senescence, including p16. However, a nevus can contain 10s to 100s of thousands of clonal melanocytes and approximately 20-30% of melanoma are thought to arise in association with a pre-existing nevus. more...
