To date, familial partial lipodystrophy (FPLD) has been known to consist of seven types, and FPLD type 3 is a rare autosomal dominant genetic disorder caused by mutations of peroxisome proliferator-activated receptor γ gene. In this issue, Dr. Iizaka and colleague report the first pedigree of FPLD 3 in Japanese exemplifying prolonged insulin resistant diabetes mellitus, liver steatosis and hypertriglyceridemia with a relatively low degree of BMI and percentage of body fat. For all endocrinologists, attention should be paid to avoid overlooking lipodystrophy syndromes.
Molecular research on agonists / antagonists / inverse agonists in a variety of G-protein coupled receptors (GPCRs) has long attracted robust attention of endocrinologists. In this issue, Dr. Nagayama and Dr. Nishihara contributes an encyclopedic, well-organized article on the update of antagonists / inverse agonists research around the thyrotropin receptor (TSHR), providing us with promising therapeutic potential for Graves’ hyperthyroidism, non-autoimmune hyperthyroidism, thyroid cancer and resistance to thyroid hormone.
It has long been recognized that uncontrolled high blood pressure, dysmetabolism of glucose and lipids, and sustained inflammation and fibrosis are involved in the pathophysiology and progression of diabetic kidney disease (DKD) in an extremely complexed manner. It is therefore exactly a herculean issue to accurately identify patients with higher risks than we would imagine for end-stage renal diseases (ESRDs). In the October issue, Dr. Xu Ning and colleague provide an attractive review article focusing on potentials of mesenchymal stem cells (MSCs) for the treatment of such an intractable medical condition.
Epigenome-based drugs such as inhibitors against DNA methyltransferases (DNMTs) and histone deacetylase (HDACs) have long been employed for the treatment of a variety of malignancy and pre-cancer status. In this issue, Dr. Rie Hagiwara and colleague provide a convincing data set of in vitro experiments demonstrating a selective HDAC6 inhibitor, tubastatin A substantially suppresses the growth of as well as the ACTH secretion from a murine corticotroph cell line, AtT-20. The present study may open a fresh avenue for brand-new therapeutics in humans on pituitary neuroendocrine tumors including Cushing’s disease.
Science and clinics on phosphate homeostasis are no doubt an authentic, royal road to endocrinology. As most of readers of Endocrine Journal well recognize, basic scientists and endocrinologists in Japan have made a huge contribution to the molecular medicine on fibroblast growth factor 23 (FGF 23) in this academic field. To STATE-OF-THE-ART REVIEW IN ENDOCRINOLOGY in this issue, Dr. Michigami contributes an extensive, well-organized article on the recent research progress in phosphate homeostasis and related disorders with a particular emphasis on FGF 23, providing us with an invaluable perspective for cutting-edge area of bone-mineral endocrinology.
