Ghrelin–LEAP2 interactions along the stomach–liver axis
Katsuya Sakai, Yuki Nakazato, Yuki Shiimura, Weidong Zhang, Masamitsu Nakazato
Recommendation from the Editor in Chief
There are examples where distinct two peptide ligands respectively act as an agonist and antagonist on the same receptor. To my knowledge, the best-known one is related with the story that alpha-MSH and agouti-related peptide (AgRP) act on the melanocrtin-4 receptor (MC4R) as an agonist and antagonist, thereby minutely regulating appetite and body weight. In this issue, Dr. Katsuya Sakai and Professor Masamitsu Nakazato, a world-renowned physician scientist on research of orexigenic hormone ghrelin, provide us with well-organized, fabulous review article focusing on the dynamic interaction between ghrelin and LEAP-2 (liver-expressed antimicrobial peptide 2) in terms of stomach-liver axis-driven appetite control. Indeed, ghrelin and LEAP-2 respectively act as an agonist and antagonist on the same receptor, GHSR (growth hormone secretagogue receptor). Our editorial team has a firm belief that all readers are surely motivated by the real deal of authentic endocrinology and cutting-edge medicine on GPCR signal transduction in this article.

Ethnicity-dependent differences in drug responsiveness have attracted broad attention also in endocrinological science. In this issue, Dr. Akira Shimatsu and Professor Beverly MK Biller at Massachusetts General Hospital, an active member of international honorary editors of Endocrine Journal, contribute an insightful original article focusing on ethnicity-related impact of oral 11beta-hydroxylase inhibitor, Osilodrostat between patients with Cushing’s disease of Asian and non-Asian origin. In comparison with non-Asians, Asian patients required apparently-lower doses of the drug to achieve clinical benefits, whereas adverse events related with hypocortisolism were manifested in Asians. As authors stated, this study is the first to compare the impact of drug therapy for patients with Cushing’s disease between Asian and non-Asian origin. Although ethnicity-dependent differences in bioavailability of the drug would be involved, elucidation of the entire picture is strongly anticipated.

Relationship between Ca2+ and cAMP as second messengers in ACTH-induced cortisol production in bovine adrenal fasciculata cells
Masahiko Kutsukake, Naoko Kuwabara, Yoshikazu Miyate, Kenzo Kudo, Shoko Goto, Eiichi Taira, Eiichi Tachikawa
Recommendation from the Editor in Chief
It is well known that both Ca 2+ and cAMP play critical roles in ACTH-driven cortisol production by adrenal fasciculate cells. However, the division of role for Ca 2+ and cAMP in this paradigm still remains obscure. In the December Issue, Dr. Masahiko Kutsukake and colleague elegantly unraveled such a long-standing enigma via sophisticated cellular experiments, demonstrating that cortisol production under steady state is preferentially mediated by Ca 2+, but cAMP also participates under stressful conditions where ACTH demand is increased to adapt exaggerated stress.

It is well recognized that a line of symptoms of neurohypophyseal diabetes insipidus (NDI), also known as arginine vasopressin (AVP) deficiency, are masked under the condition of adrenal insufficiency. However, molecular mechanisms whereby polyuria manifests after the administration of glucocorticoids in patients with masked NDI have not been fully elucidated. Kurimoto J and colleague elegantly solved this long-lasting enigma via comprehensive analyses including patients with masked NDI as well as murine model of familial NDI. They provide a convincing proof that mineralcorticoids directly attenuate the expression of aquaporin-2 in the apical membrane of collecting duct, thereby leading to the increase in urine volume in patients with NDI.

Convincing and conveniently-evaluated molecular biomarkers for prediction and assessment of metabolic syndrome are warranted to realize precision health as well as precision medicine in lifestyle-related diseases. In the present study, Yamazaki M and colleague provide intriguing evidence that level of DNA methylation of the gene encoding thioredoxin-interacting protein, a key inhibitor of cellular oxidation, is significantly decreased in peripheral blood cells from subjects with metabolic syndrome. Further extensive studies are strongly expected to see whether such a status of hypomethylation is clinically relevant to the extent of systemic oxidative stress and would be reversible in response to a line of lifestyle modifications or metabolic surgeries.
