A histone deacetylase SIRT6 regulates the transcription of various genes involved in lipid metabolism. Fatty acid (FA) oxidation plays a pivotal role in maintaining hepatic lipid homeostasis, and its dysregulation significantly contributes to lipotoxicity and inflammation, driving the progression of steatotic liver disease. While SIRT6 is known to activate peroxisome proliferator-activated receptor-alpha (PPARα), a central regulator of FA oxidation, the development of SIRT6 activators capable of enhancing FA oxidation and mitigating steatotic liver disease has yet to be achieved. This study evaluated the effect of MDL-800, a selective SIRT6 activator, on the expression of PPARα and genes related to FA oxidation. In AML12 mouse hepatocytes, MDL-800 treatment activated SIRT6 but unexpectedly decreased the expression of PPARα and its FA oxidation-associated target genes. Furthermore, OSS128167, a selective SIRT6 inhibitor, did not reverse the suppressive effects of MDL-800 on PPARα, suggesting that MDL-800 downregulates PPARα and FA oxidation-related genes through a mechanism independent of SIRT6 activation. Mechanistic investigations revealed that MDL-800 increased the production of reactive oxygen species and activated stress kinases. The inhibition of PPARα by MDL-800 was reversed by co-treatment with the antioxidant N-acetylcysteine or the JNK inhibitor SP600125.In summary, MDL-800 suppresses PPARα and FA oxidation-related genes primarily through the induction of oxidative stress in hepatocytes, independent of its role as a SIRT6 activator.

Purpose: As nursing continues to advance through digital health, clinical specialization, and interdisciplinary research, early-career nurse scientists are central to advancing innovation. However, Korea lacks a structured platform to support their research, collaboration, and career development. This review aimed to identify the needs of early-career nurse scientists and examine international best practices to guide the creation of an effective communication platform. Methods: This study involved a secondary analysis of the final report from the project “Establishment of a communication platform for young nursing scientists,” carried out by the Korean Society of Nursing Science. The report comprises data from focus group interviews with domestic graduate students and early-career researchers, a literature review of international communication and support systems, and a global policy analysis related to young nursing scientists. Based on this report, the present review synthesizes key findings and draws implications for the development of a communication platform in Korea. Results: International examples, such as grant writing programs, mentoring initiatives, and digital collaboration hubs, showed positive outcomes in strengthening research capacity and promoting the professional growth of nurse scientists. Based on these findings, key considerations for platform development include: (1) establishing clear leadership and a participatory governance model; (2) providing demand-driven content such as research guides, mentoring, and mental health resources; (3) implementing mechanisms to ensure sustainability, content quality, and user data protection; and (4) designing an integrated platform that fosters synergy across research, policy development, education, and global networking. Conclusion A digital platform for early-career nurse scientists should function not merely as an information portal, but also as dynamic infrastructure for collaboration, mentorship, and growth. It is recommended that the Korean Society of Nursing Science spearhead this initiative, with governmental support, to enhance the research capacity and expand the global engagement of Korean nursing scientists.

Purpose: Relative energy deficiency in sport (REDs) is a syndrome of physiological and/or psychological functioning experienced by female and male athletes that is caused by exposure to problematic low energy availability. For the prevention and intervention of REDs, awareness of REDs among sports physicians is important, but it is largely unknown. This study aimed to survey the awareness and clinical treatment experience of REDs in sports physicians. Methods: We conducted an online survey to assess awareness of the triad and REDs among sports physicians and members of The Korean Society of Sports Medicine. Results: A total of 69 members (62.2% male, including sports physicians) to this survey. Most participants (84.1%) were aware of the triad compared to fewer with awareness regarding REDs (23.2%). People who knew about the difference between REDs and triad was 33.3%, which was lower than those who did not (66.6%). Only 10.1% of the study subjects had experience treating REDs patients, and the biggest difficulty in treating patients was a lack of information and education (50.7%). It appeared that the most information about REDs was obtained from academic conferences (59.4%). Conclusion This survey found relatively low awareness of REDs among physicians treating athletes and sports professionals. Considering the various negative effects of REDs on athlete health and performance, education and promotion are needed to increase awareness among sports physicians and sports professionals.
