deletion of the putative tumor suppressor gene, g0s2, does not affect progression of eμ-myc driven lymphomas in mice.several recent reports have suggested that the g0/g1 switch gene 2 (g0s2) is a potential tumor suppressor in leukemia. here we show that deletion of the g0s2 gene in mouse does not affect the latency of cancer progression in the eμ-myc model of lymphoma. our findings do not rule out the possibility that g0s2 may be playing a role in other forms of leukemia, but clearly show that the commonly used eμ-myc transgenic is not the correct model to conduct studies on g0s2.201626654706
combined loss of puma and p21 accelerates c-myc-driven lymphoma development considerably less than loss of one allele of p53.the tumor suppressor p53 is mutated in ~50% of human cancers. p53 is activated by a range of stimuli and regulates several cellular processes, including apoptotic cell death, cell cycle arrest, senescence and dna repair. p53 induces apoptosis via transcriptional induction of the bh3-only proteins puma (p53-upregulated modulator of apoptosis) and noxa, and cell cycle arrest via p21. induction of these processes was proposed to be critical for p53-mediated tumor suppression. it is therefore surpri ...201626640149
