However  the mechanisms by which p53 exerts its tumor suppressive function is still unclear. While PUMA/BBC3 and NOXA/PMAIP1 are known to be important in p53 dependent apoptosis  and p21/CDKN1A is crucial for p53 dependent cell cycle arrest  we demonstrate that zebrafish lacking puma  noxa  and p21 do not show a predisposition to cancer. This suggests that additional p53 transcriptional targets are sufficient for its tumor suppressive function. Contrary to the prevailing belief that p21 is the key regulator of p53 dependent cell cycle arrest  we provide evidence that p53 can still induce cell cycle arrest in the absence of p21  following DNA damage or loss of mdm2 p53 activation in the absence of stress. This implies the involvement of other p53 transcriptional targets in mediating p53 dependent cell cycle arrest. Since p53 tumor suppression is conserved across multiple vertebrate species  we conducted a cross species comparative analysis of p53 dependent transcriptional profiles to identify a conserved set of 136 p53 upregulated transcripts. Our analysis stresses the importance of ortholog to paralog analysis across species  since in many cases the paralog but not ortholog in differing species is p53 dependent. Additionally  we performed a CRISPR/Cas9 G0 \u201ccrispant\u201d screen in a genetic background lacking mdm2  puma  noxa  and p21 to identify key components involved in p53 dependent cell cycle arrest. Our findings revealed that ccng1  fbxw7  and foxo3b play an important role in this process. Overall design: RNA sequencing was performed on zebrafish quadruple knockouts of mdm2  puma  noxa  and p21 at 18 hpf Sibling controls from the same batch  including mdm2+/  or mdm2+/+; puma / ; noxa / ; and p21 /  embryos  were also harvested to extract RNA for comparison.", null, "pubmed:40487439", null, "Zebrafish Abnormal MPNP 18hpf 1", "GSM8772775", null, "source name:30 hpf embryos|tissue:30 hpf embryos|genotype:mdm2 / ; puma / ; noxa / ; p21 / |geo loc name:missing|collection date:missing", "Zebrafish Abnormal MPNP 18hpf 1", "Raw sequencing reads were aligned to the Danio rerio GRCz11 genome assemblies using STAR version 2.7.3a  GCC 6.4.0 2.28 with default setting.
