BACKGROUND： Reports of fiver transplantation （LT） in patients with mixed hepatocellular carcinoma/cholangiocarcinoma （HCC/CC） and intrahepatic cholangiocarcinoma （ICC） are modest and have been mostly retrospective after pathological categorization in the setting of presumed HCC. Some studies suggest that patients undergoing LT with small and unifocal ICC or mixed HCC/CC can achieve about 40%-60% 5-year post-transplant survival. The study aimed to report our experience in patients undergoing LT with explant pathology revealing HCC/CC and ICC. METHODS： From a prospectively maintained database, we performed cohort analysis. We identified 13 patients who underwent LT with explant pathology revealing HCC/CC or ICC. RESULTS： The observed recurrence rate post-LT was 31% （4/13） and overall survival was 85%, 51%, and 51% at 1, 3 and 5 years, respectively. Disease-free survival was 68%, 51%, and 41% at 1, 3 and 5 years, respectively. In our cohort, four patients would have qualified for exception points based on updated HCC Organ Procurement and Transplantation Network imaging guidelines. CONCLUSIONS： Lesions which lack complete imaging characteristics of HCC may warrant pre-LT biopsy to fully elucidate their pathology. Identified patients with early HCC/CC or ICC may benefit from LT if unresectable. Additionally, incorporating adjunctive perioperative therapies such as in the case of patients undergoing LT with hilar cholangiocarcinoma may improve outcomes but this warrants further investigation.

Plants need to respond quickly and appropriately to various types of light signals from the environment to optimize growth and development. The immediate response to shading, reduced photon flux （low light）, and changes in spectral quality involves changes in gene regulation. In the case of more persistent shade, the plant shows a dramatic change in the organization of chromatin. Both plant responses are controlled via photoreceptor signaling proteins. Re- cently, several studies have revealed similar features of chromatin reorganization in response to various abiotic and biotic signals, while others have unveiled intricate molecular networks of light signaling towards gene regulation. This opinion paper briefly describes the chromatin （de）compaction response from a light-signaling perspective to provide a link be- tween chromatin and the molecular network of photoreceptors and E3 ubiquitin ligase complexes.
