Background: The xenotransplant clinical trial with human subjects seems to be technically feasible, however, it needs the strict regulatory framework from the domestic as well as the international level to make sure the safety of the human subject and the general public.
Methods: The authors reviewed and introduced the current regulations regarding the xenotransplant clinical trial in Korea focusing on the recently stipulated act (Advanced Regenerative Medicine and Biopharmacology Act, ARMBA) and the role of the related government agencies and health institutions.
Results And Conclusion: Korea is ready to conduct the xenotransplant clinical trial with human subjects in the current regulatory framework satisfying the requirements of the international guidance. The responsible governmental agencies would collaborate in control the xenotransplant clinical trial under the ARMBA and other related acts and guidance.

Xenotransplantation of porcine organs has made remarkable progress towards clinical application. A key factor has been the generation of genetically multi-modified source pigs for xenotransplants, protected against immune rejection and coagulation dysregulation. While efficient gene editing tools and multi-cistronic expression cassettes facilitate sophisticated and complex genetic modifications with multiple gene knockouts and protective transgenes, an increasing number of independently segregating genetic units complicates the breeding of the source pigs.

Purpose: Oxymatrine has potent anti-cancer activity, but its exact mechanism in liver cancer remains elusive. The present study was designated to explore oxymatrine's effect and the potential mechanism on Programmed cell death-ligand 1 (PD-L1) expression and ferroptosis in liver cancer.
Methods: Oxymatrine's influence on PD-L1 expression and ferroptosis-related proteins in liver cancer cells was explored in vitro and in vivo utilizing Western blotting, qRT-PCR, immunofluorescence, ELISA, H&E staining, immunohistochemistry, as well as detection of Fe, ROS, and MDA.

Based on promising results obtained in primate models, pioneers in the US have now started to explore the new frontier of genetically-edited pig-to-human transplantation. The recent transition of xenotransplantation into clinical medicine has included transplants in brain-dead subjects and the compassionate use of xenotransplants in living recipients without options for allotransplantation. While the barrier of hyperacute rejection seems to be successfully overcome by gene editing of donor pigs, the occurrence of accelerated rejection could pose significant limitations to the success of the procedure.

Can it be ethical to conduct xenotransplant research on a human brain-dead decedent (HB-DD) whose organs could otherwise be given to persons in need? The ethical consensus is that it is better to save existing persons via organ donation than to devote a HB-DD to research that will not directly benefit anyone. I argue otherwise. Given how rapidly xenotransplant research is progressing, and its clinical promise in the next couple of years or decades, I argue that it can be ethical to conduct xenotransplant research on a HB-DD whose organs could otherwise be given to individuals in need.
