Project description:Although being essential to respiratory and reproductive tracts multiciliogenesis, TAp73 is dispensable for multiciliogenesis in the ventricles. TAp73 KO is accompanied by dramatic changes in ciliogenic microRNAs miR34bc and miR449 family members, suggestin TAp73 functions partially thorugh posttranscriptional nodes in brain ciliogenesis.

Project description:The aim of the experiment was to analyse the gene expression differences between MEFs containing TAp73 or without TAp73, at basal levels in normal culture conditions, and upon treatment with hypoxia (by incubation in 1% oxygen) for 4 or 8 hrs. The analysis indicate that absence of TAp73 leads to changes in multiple cellular and biological processes.

TAp73-/- and Tap73+/+ MEFs that were untreated, or treated with hypoxia (in 1% oxygen) for 4 and 8 hours were used for gene expression analysis

Project description:Hepatocyte dedifferentiation is a major source of hepatocellular carcinoma (HCC), but its mechanisms are unknown. We explored the p73 expression in HCC tumors and studied the effects of transcriptionally active p73 (TAp73) in HCC cells. Expression profiles of p73 and patient clinical data were collected from the Genomic Data Commons (GDC) data portal and the TSVdb database, respectively. Global gene expression profiles were determined by pan-genomic 54K microarrays. The Gene Set Enrichment Analysis was used to identify TAp73-regulated gene sets. The effects of TAp73 were analyzed in monolayer cell culture, 3D-tumoroid and xenograft models in zebrafish using western blot, flow cytometry, fluorescence imaging, real-time polymerase chain reaction (RT-PCR), immunohistochemistry and morphological examination. TAp73 was significantly upregulated in HCC, and its high expression indicated poor patient survival. The induced expression of TAp73 caused landscape expression changes including genes involved in growth signaling, cell cycle, stress response, immunity, metabolism and development. HCC cells overexpressing TAp73 had lost hepatocyte lineage biomarkers including ALB, CYP3A4, AFP, HNF4α. In contrast, TAp73 upregulated genes promoting cholangiocyte lineage such as YAP, JAG1 and ZO-1, accompanied with an increase in metastatic ability. Our findings strongly suggest that TAp73 is a major promoter of malignant dedifferentiation of HCC cells Hepatocellular carcinoma (HCC) is a highly complex and heterogeneous type of cancer. Hepatocyte dedifferentiation is one of the important steps in the development of HCC. However, its molecular mechanisms are not well known. In this study, we report that TAp73 which is the major transcriptionally active form of p73 is overexpressed in HCC. Mechanically, TAp73 suppresses the expression of the hepatocyte markers including CYP3A4, AFP, ALB, HNF4a, while increasing the expression of several cholangiocyte markers in HCC cell lines. In conclusion, this report reveals a pro-oncogenic role for TAp73 in liver cancer.
