Partial hepatectomy accelerates colorectal metastasis by priming a prometastatic niche in the liver

Project description:Despite being the standard of care for patients with Stage IV colorectal cancer (CRC), the effects of a resection of liver metastasis on the metastatic disease are poorly understood. To elucidate the influence of surgical metastasectomies on metastasized CRC, we investigated the cellular and molecular effects of partial hepatectomy in a mouse model of orthograde CRC liver metastasis.

Comparison of hepatic gene change after partial hepatectomy

Project description:Partial hepatectomy, resection of a portion of liver mass, indues significant liver regenerative responses that consist of numerous genetic changes. To identify specific genetic changes, we compare the liver of mice underwent either hepatectomy or sham operation.

Hepatic gene expression during liver regeneration in response to partial hepatectomy: late time points (24h, 38h, 48h)

Project description:The process of liver regeneration can be divided into a series of stages that include initial inductive or priming events through cellular mitosis. Following two-thirds liver resection, the liver undergoes the “priming” phase, in which cytokines TNF-a and IL-6 activate their respective receptors in hepatocytes. This leads to the activation of several key transcription factors: NF-kB, AP-1, Stat 3, Stat 1, and C/EBP-b and -d . These transcription factors induce the expression of immediate early genes. HGF is also expressed at this time and involved in the transition of quiescent hepatocytes into the G1 phase of the cell cycle. During the G1 phase, delayed early genes are expressed followed by induction of cell cycle–related genes, both of which require new protein synthesis for their production. Increased expression of FoxM1B and TGF-a occurs at the G1/S transition and is correlated with increased expression of cyclinD1 and decreased expression of cdk inhibitors. During the G2/M phase of the cell cycle, FoxM1B directly elevates cyclinB1, cyclinB2, and cdc25B expression. Additionally, FoxM1B is associated with increased cyclinF and p55cdc, which are involved in completion of the cell cycle following partial hepatectomy. In mice, two-thirds partial hepatectomy promotes proliferation of liver cells and rapid growth of the remaining liver tissue, resulting in complete restoration of organ mass in approximately 7 days (Mackey S. et al. Hepatology 2003 Dec;38(6):1349-52). Liver tissue was collected 0h, 24h, 38h, and 48h after partial hepatectomy or sham surgery from both young (5-6 months) and old (25-27 months) CB6F1 mice. All control and partial hepatectomy samples were assayed in triplicate. Relative gene expression levels were determined using Affymetrix moe430_2 oligo arrays.

Hepatic gene expression during liver regeneration in response to partial hepatectomy: early time points (0.5h,1h,2h,4h)

All control and partial hepatectomy samples were assayed in triplicate. Relative gene expression levels were determined using Affymetrix Murine Genome U74 Version 2 Array.

Expression data from rat hepatocyte during liver regeneration after partial hepatectomy

Project description:The recovery of liver mass is mainly mediated by proliferation and enlargement of hepatocytes after partial hepatectomy. Studying the gene expression profiles of hepatocytes after partial hepatectomy will be helpful in exploring the mechanism of liver regeneration. We used microarrays to further highlight the regulatory role of hepatocyte in liver regeneration at gene transcription level.

Partial hepatectomy 1, 2, 4, 6h

Project description:Adult male Sprague-Dawley rats (275-350 g) were anesthetized and subjected to two-thirds PHx. Liver sections removed by partial hepatectomy (PHx) were collected and used both as controls (time=0) and as individual reference material for each animal to reduce the error introduced by animal-to-animal variability. At 1, 2, 4, and 6 hours following PHx, rats were killed and liver samples were harvested. Keywords: Time series PHx (1, 2, 4, 6h)

Effect of conditional deletion of S6 ribosomal protein following partial hepatectomy

Project description:Deletion of the RPS6 gene in mouse liver results in the inhibition of 40S ribosome biogenesis and the failure of hepatocytes to enter S-phase following partial hepatectomy. This microarray experiment was designed to assess the effects of RPS6 deletion on the expression of genes involved in liver regeneration following partial hepatectomy. Keywords: time course, liver
