Clusterin, a haploinsufficient tumor suppressor gene in neuroblastomas.
BACKGROUND Clusterin expression in various types of human cancers may be higher or lower than in normal tissue, and clusterin may promote or inhibit apoptosis, cell motility, and inflammation. We investigated the role of clusterin in tumor development in mouse models of neuroblastoma. METHODS We assessed expression of microRNAs in the miR-17-92 cluster by real-time reverse transcription-polym...
متن کاملASPP2 is a haploinsufficient tumor suppressor that cooperates with p53 to suppress tumor growth.
ASPP2 stimulates the apoptotic function of the p53 family in vivo. We show here that ASPP2-/- pups died before weaning. This postnatal lethality was significantly enhanced in p53+/- background and both deletions are synthetic lethal. ASPP2+/- mice developed spontaneous tumors. The tumor onset was accelerated by gamma-irradiation or in p53+/- background. Tumors derived from ASPP2+/- mice retaine...
متن کامل53BP1 cooperates with p53 and functions as a haploinsufficient tumor suppressor in mice.
p53 binding protein 1 (53BP1) is a putative DNA damage sensor that accumulates at sites of double-strand breaks (DSBs) in a manner dependent on histone H2AX. Here we show that the loss of one or both copies of 53BP1 greatly accelerates lymphomagenesis in a p53-null background, suggesting that 53BP1 and p53 cooperate in tumor suppression. A subset of 53BP1-/- p53-/- lymphomas, like those in H2AX...
متن کاملDdb2 is a haploinsufficient tumor suppressor and controls spontaneous germ cell apoptosis.
Damage-specific DNA-binding (DDB) protein heterodimer has been extensively studied in the context of nucleotide excision repair. However, the smaller subunit, DDB2, is also implicated in tumor suppressor p53-mediated processes, although the precise details of the DDB2 - p53 interactions are unknown. Here, we report that Ddb2(-/-) and Ddb2(+/-) mice have shortened lifespans and increased frequen...
متن کاملBeclin 1, an autophagy gene essential for early embryonic development, is a haploinsufficient tumor suppressor.
The biochemical properties of beclin 1 suggest a role in two fundamentally important cell biological pathways: autophagy and apoptosis. We show here that beclin 1-/- mutant mice die early in embryogenesis and beclin 1+/- mutant mice suffer from a high incidence of spontaneous tumors. These tumors continue to express wild-type beclin 1 mRNA and protein, establishing that beclin 1 is a haploinsuf...
