Liver Transplantation With Two-stage Liver Resection in Unresectable Liver Cancer , Metastases or Emd-stage Liver Disease (LTLR-LC)

ABSTRACT: Colon cancer and primary liver cancer are common malignant tumors with low survival rate worldwide, and unresectable primary liver cancer and colon cancer liver metastases have worse prognosis. End-stage liver disease is equated with advanced liver disease, liver failure and decompensated cirrhosis because they are generally irreversible. Liver transplantation is a treatment option for the above-mentioned patients and is expected to improve the prognosis of the patients, but the biggest problem faced by such patients is the shortage of donor livers. Recently, a new surgical modality, resection and partial liver segment 2-3 transplantation with delayed total hepatectomy (RAPID), can greatly alleviate these problems.Based on clinical surgical experience, our center proposes and designs a clinical study of adjuvant liver transplantation combined with two-stage hepatectomy in the treatment of patients with unresectable primary liver cancer, colorectal cancer liver metastases, or end-stage liver disease. By improvement of RAPID operation, the safety and efficacy of this treatment method in patients with those disease were evaluated.

Project description:Liver is uniquely capable to repair itself after injury. Multiple molecular and biochemical processes initiated after partial hepatectomy, lead to proliferation of all cells within the liver. MicroRNAs (miRNAs) are a class of highly abundant non-coding RNA molecules that cause post-transcriptional gene repression and are involved in several biological processes including cell cycle regulation and differentiation. We examined the expression levels of miRNAs in liver tissue received from control mice (L0) and compared them with the corresponding levels in liver tissue 12 hours after liver regeneration induced by 2/3 partial hepatectomy (L12). MicroRNA expression was investigated using microRNA profiling. Further qPCR analysis was used for validation of the differentially expressed microRNAs at an early stage of liver regeneration, induced by 2/3 partial hepatectomy. TargetScan and Gene Ontology (GO) analysis was performed in order to identify the possible miRNA target genes and their ontology, respectively. A subset of miRNAs were found to be differentially expressed during liver regeneration. Mmu-miR-21 and mmu-miR-30b* showed the higher levels of up-regulation in liver tissue from the hepatectomized mice at the end of the experiment (L12) compared to the sham operated mice (L0). Mmu-miR-21 up-regulation was further confirmed by qPCR. In situ hybridization (ISH) revealed that mmu-miR-21 exhibited the higher levels of expression at 12 hours post hepatectomy. On the contrary, mmu-miR-34c*, mmu-miR-144, mmu-miR-207, mmu-miR-207, mmu-miR-451, mmu-miR-582-3p and mmu-miR-290-5p exhibited <0.5 down-regulation in liver tissue after partial hepatectomy in L12 vs. L0 mice. Microarrays and qPCR results were in good agreement (Pearson correlation = 0.881). Our results provide important information regarding how microRNAs are deferentially expressed in murine liver tissue before and after partial hepatectomy. The early up-regulation of mmu-miR-21 during the process of liver regeneration suggests a regulatory role in liver regeneration in vivo.
