Background: Minimally invasive surgeries are increasingly central to modern medicine, particularly in liver transplantation. These techniques, which offer reduced trauma, precise operations, minimal bleeding, and swift recovery, are, however, unevenly adopted across China. Only a limited number of centers routinely perform minimally invasive donor hepatectomies, indicating a significant imbalance in the development and application of these advanced procedures.

Article Synopsis
  • A retrospective study compared the effectiveness and safety of transarterial chemoembolization plus lenvatinib and tislelizumab (TACE-Len-T) versus just transarterial chemoembolization plus lenvatinib (TACE-Len) for patients with unresectable hepatocellular carcinoma (uHCC).
  • Results showed that patients receiving TACE-Len-T had significantly longer overall survival (OS) and progression-free survival (PFS), along with a higher overall objective response rate (ORR) and disease control rate (DCR) compared to those receiving TACE-Len.
  • Both treatment groups had similar rates and severity of adverse events, indicating that TACE-Len-T is safer while providing

Article Synopsis
  • Scientists wanted a better way to predict how well liver transplants work, so they created a new model that uses information from both donors and recipients.
  • They tested this model with data from 528 patients and found that specific factors, like cold ischemia time (how long the liver was without blood) and a score called MELD, could help predict survival after the transplant.
  • The new model, called the CIT-MELD Index (CMI), was found to be more effective than older methods at predicting outcomes and understanding the risks involved in liver transplants.

The residual dextran impurities in the upstream process significantly impact the crystallization of starch-based functional sugar and the related food properties. This study intends to reveal the mechanism of dextran's influence on trehalose crystallization, and build a relationship among the dextran in syrup and the physicochemical and functional properties of trehalose. Instead of incorporating into the crystal lattice, dextran changes the assembly rate of trehalose molecules on crystal surface.

Long-term stem cell survival in the cirrhotic liver niche to maintain therapeutic efficacy has not been achieved. In a well-defined diethylnitrosamine (DEN)-induced liver fibrosis/cirrhosis animal model, we previously showed that liver-resident stem/progenitor cells (MLpvNG2 cells) or immune cells have improved survival in the fibrotic liver environment but died via apoptosis in the cirrhotic liver environment, and increased levels of hepatocyte growth factor (HGF) mediated this cell death. We tested the hypothesis that inhibiting HGF signaling during the cirrhotic phase could keep the cells alive.

Allostimulated CD8 T cells (aCD8 T cells), as the main mediators of acute liver rejection (ARJ), are hyposensitive to apoptosis due to the inactivation of death receptor FAS-mediated pathways and fail to allow tolerance induction, eventually leading to acute graft rejection. Although tacrolimus (FK506), the most commonly used immunosuppressant (IS) in the clinic, allows tolerance induction, its use is limited because its target immune cells are unknown and it is associated with increased incidences of malignancy, infection, and nephrotoxicity, which substantially impact long-term liver transplantation (LTx) outcomes. The dark agouti (DA)-to-Lewis rat LTx model is a well-known ARJ model and was hence chosen for the present study.

Helicase-like transcription factor (HLTF) has been found to be involved in the maintenance of genome stability and tumour suppression, but whether its downregulation in cancers is associated with posttranslational regulation remains unclear. Here, we observed that HLTF was significantly downregulated in hepatocellular carcinoma (HCC) tissues and positively associated with the survival of HCC patients. Mechanistically, the decreased expression of HLTF in HCC was attributed to elevated β-TrCP-mediated ubiquitination and degradation.
