Recent studies demonstrated that proinflammatory migration inhibitory factor(MIF) blocks p53-dependent apoptosis and interferes with the tumor suppressor activity of p53. To explore the mechanism underlying this MIF-p53 relationship, we studied spontaneous tumorigenesis in genetically matched p53-/- and MIF-/-p53-/- mice. We show that the loss of MIF(More)
A core evolutionary function of the p53 family is to protect the genomic integrity of gametes. However, the role of p73 in the male germ line is unknown. Here, we reveal that TAp73 unexpectedly functions as an adhesion and maturation factor of the seminiferous epithelium orchestrating spermiogenesis. TAp73 knockout (TAp73KO) and p73KO mice, but not ΔNp73KO(More)
Over the past years considerable effort has been directed toward identification of genes involved in cancer. We know now that mutations in more than 1% of human genes (out of ~20,000–25,000 genes in human genome) could play a role in cancer. 1 Major advances have been made in understanding the processes involved in cancer progression. Much of this knowledge(More)
Transcriptional silencing of the p73 gene through methylation has been demonstrated in human leukemias and lymphomas. However, the role of p73 in the malignant process remains to be explored. We show here that p73 acts as a T cell-specific tumor suppressor in a genetically defined mouse model, and that concomitant ablation of p53 and p73 predisposes mice to(More)
