Project description:As the central hub metabolic organ bodily, the liver is paramount to keep whole-body energy homeostasis. Further, mitochondria are the central metabolic hub within cells to connect the main catabolized, energy production, and hormonal signaling pathways. It is evident that mitochondrial dysfunction may play a critical role in the development of NASH. Accordingly, understanding the underlying mechanisms of mitochondrial dysfunction is of importance to develop therapies for NASH. Here, we report that mice with hepatocyte-specific deletion of Tid1, encoding a mitochondrial cochaperone, tended to develop NASH-dependent HCC. The hepatocellular nodules were developed in 3-month DEN-treated Tid1-/- mice. At the age of 6 months, the DEN-treated Tid1-/- mice showed a higher number of tumors and greater tumor size than the DEN-treated Tid1+/- mice, followed by the DEN-treated WT mice. To gain insights into the mRNA changes during NASH-HCC progress, we performed an RNA-seq analysis with livers collected from 6-month DEN-treated mice.

Project description:To look for age-related changes in the liver that take place during DNA damage resolution, we used RNAseq gene expression analysis to characterize mRNA expression profile in livers from 1-month vs. 6-month-old mice either before or 2 days (representing the peak of DNA damage response) and 6 days (representing the resolution phase of DNA damage) after DEN treatment.

Project description:Liver carcinogenesis induced by DEN closely mimics the pathologies observed during human liver tumor initiation and progression. DEN treatment triggered c-Jun expression lasting up to at least 1 week in mouse livers as measured by Western blots and immunohistochemical staining. DEN-induced liver tumorigenesis was also dramatically reduced in Alfp-cre+/c-jun f/f mice, in which c-Jun is constitutively deleted in hepatocytes around birth. These data unambiguously demonstrate that c-Jun is specifically required during liver cancer initiation. We searched for cell death effectors downstream of c-Jun operating in cancer initiation. Expression profiling revealed that several cell death-associated genes were deregulated by comparing Alfp-cre+/c-junf/f and Alfp-cre-/c-jun f/f livers. Mouse livers were collected before and 48hours after diethylnitrosamine treament (100mg/kg body weight). Whole genome expression profiles were analyzed using total RNAs extracted from the whole liver samples.

Project description:SRSF2 flanked with flox was specifically depleted in the livers by Alb-Cre(HKO),and took the intact ones as contorl(WT).Near 70% of the HKO livers spontaneously developed malignant tumors(took the tumor areas as tumor while the tumor-adjacent as nontumor).Then total RNAs of 2-month WT/HKO and 12-month WT/nontumor/tumor were isolated and performed the next generation sequencing. We profiled the gene expression regulated by Cre-loxp-mediated knockout system.
