Abstract
Old animals display significant alterations in sleep-wake patterns such as increases in sleep fragmentation and sleep propensity. Here, we demonstrated that PR-domain containing protein 13 (Prdm13)+ neurons in the dorsomedial hypothalamus (DMH) are activated during sleep deprivation (SD) in young mice but not in old mice. Chemogenetic inhibition of Prdm13+ neurons in the DMH in young mice promotes increase in sleep attempts during SD, suggesting its involvement in sleep control. Furthermore, DMH-specific Prdm13-knockout (DMH-Prdm13-KO) mice recapitulated age-associated sleep alterations such as sleep fragmentation and increased sleep attempts during SD. These phenotypes were further exacerbated during aging, with increased adiposity and decreased physical activity, resulting in shortened lifespan. Dietary restriction (DR), a well-known anti-aging intervention in diverse organisms, ameliorated age-associated sleep fragmentation and increased sleep attempts during SD, whereas these effects of DR were abrogated in DMH-Prdm13-KO mice. Moreover, overexpression of Prdm13 in the DMH ameliorated increased sleep attempts during SD in old mice. Therefore, maintaining Prdm13 signaling in the DMH might play an important role to control sleep-wake patterns during aging.

Abstract
Age-related tooth loss impedes mastication. Epidemiological and physiological studies have reported that poor oral hygiene and occlusion are associated with cognitive decline. In the present study, we analyzed the mechanism by which decreased occlusal support following bilateral extraction of the maxillary first molars affects cognitive functions in young and aged mice and examined the expression of brain-function-related genes in the hippocampus and hypothalamus. We observed decreased working memory, enhanced restlessness, and increased nocturnal activity in aged mice with molar extraction compared with that in mice with intact molars. Furthermore, in the hypothalamus and hippocampus of molar-extracted aged mice, the transcript-level expression of Bdnf, Rbfox3, and Fos decreased, while that of Cdkn2a and Aif1 increased. Thus, decreased occlusal support after maxillary first molar extraction may affect cognitive function and activity in mice by influencing aging, neural activity, and neuroinflammation in the hippocampus and hypothalamus.

Abstract
Simple Summary Static electric field (SEF) treatment by high-voltage alternating current is a traditional complementary medicine in Japan. Although it is believed that the SEF-induced electric current serves to regulate cellular or humoral responses in patients, the mechanism for SEF treatment remains poorly understood. There have been very few experimental reports on the biological action with SEF treatment. The aim of this study was to elucidate the effects of SEF treatment on vitamin D3 (Vit D3)-induced abnormalities in mice. SEF treatment improved the abnormalities in the renal function tests and the imbalance of serum electrolytes. In addition, this treatment remarkably attenuated the Vit D3-induced tissue injuries (severe tissue calcification in the kidneys, hearts, and stomachs). It was likely that the SEF treatment had some favorable effects on the metabolism of calcium. In conclusion, this study provides important evidence that SEF treatment can reduce hypercalcemia and remove calcium deposits from the renal, cardiac, and gastric tissues. SEF treatment is useful in the regulation of disorders caused by an imbalance of serum electrolytes. This study experimentally demonstrates the favorable effects of SEF treatment on Vit D3-induced hypercalcemia. For small animals, the larger the body surface area per body weight becomes, the higher the therapeutic efficacy with SEF treatment. Abstract The purpose of this study was to elucidate the effects of static electric field (SEF) treatment on vitamin D3 (Vit D3)-induced hypercalcemia and renal calcification in mice. The mice were assigned to three groups: Vit D3-treated mice, mice treated with Vit D3 and SEF (Vit D3 + SEF), and untreated mice. After the administration of Vit D3, the Vit D3 + SEF-treated mice were exposed to SEF treatment by a high-voltage alternating current over five days. Serum biochemical examinations revealed that both the creatinine and blood urea nitrogen concentrations were significantly higher in the Vit D3-treated group. Significantly, decreased Cl concentrations, and increased Ca and inorganic phosphorus concentrations, were found in the Vit D3-treated group. In the Vit D3 + SEF-treated group, these parameters returned to the levels of the untreated group. In the Vit D3-treated group, histopathological examinations showed marked multifocal calcification in the lumens of the renal tubules and the renal parenchyma. The myocardium was replaced by abundant granular mineralization (calcification), with degeneration and necrosis of the calcified fibers. The stomach showed calcification of the cardiac mucosa. SEF treatment remarkably attenuated the Vit D3-induced hypervitaminotic injuries. In conclusion, this study provides important evidence that SEF treatment can reduce hypercalcemia and remove calcium deposits from the renal, cardiac, and gastric tissues. SEF treatment is useful in the regulation of disorders caused by an imbalance of serum electrolytes.

Abstract
IL-6 is a cytokine that is involved in various physiological and pathological conditions,
and approaches using gain-of-function transgenic animals have contributed in elucidating
IL-6 function. However, studies of the multiple functions of IL-6 in vivo
are very time consuming because they require the generation of transgenic mice that harbor
the gene encoding IL-6 under the control of specific promoters to mimic different
pathologies. Here, we report the establishment of a conditional human IL-6 transgenic
mouse, LGL-IL6, which conditionally expresses human IL-6 by taking advantage of the
well-characterized Cre recombinase drivers.

Abstract
Intense expression of mRNA of endothelin-B receptor (ETBR) has been detected in the Bergmann glia of cerebellum by in situ hybridization, but the intracellular localization has not been reported because of the absence of a useful antibody for immunohistochemical investigations. We made polyclonal antibodies against the carboxyl terminus of human ETBR (420-442) and ETAR (403-427), and performed light- and electron-microscopic immunohistochemistry of the wild-type and ETBR-deficient (sl/sl) rat cerebella. Localization of ETBR during postnatal development was examined by double-staining immunofluorescence using antibodies against ETBR and S-100 beta. In the wild-type rats, ETBR immunoreactivity appeared from postnatal day 5 (P5) and was distributed diffusely in the processes and cell bodies of S-100 beta-positive glial cells. By P14, ETBR immunoreactivity was concentrated in the Golgi apparatus of Bergmann glial cell soma and the plasma membrane of its processes. The ETBR-positive astrocytes in the granular layer decreased in number during P7-14 and had disappeared by week 3. At 3 weeks, ETBR immunoreactivity was restricted to the Golgi apparatus of Bergmann glia. In the sl/sl rats, ETBR immunoreactivity was not observed at all. In contrast to ETBR, ETAR immunoreactivity appeared transiently in the cytoplasm of all astrocytes (Bergmann glia and astrocytes in the granular layer) in the 9- to 14-day-old wild rats and 7- to 14-day-old sl/sl rats, and disappeared within 3 weeks in both. Granule cells did not express immunoreactivity for ETBR and ETAR from the neonatal stage to adulthood. Changes in the intracellular localization of ETBR and transient expression of ETAR may be correlated with the changes of glial functions and proliferation during postnatal development of rat cerebellum.

Abstract
Epithelial proliferation, extracellular matrix remodeling, and interstitial inflammation are central elements in the pathogenesis of slowly progressive polycystic kidney disorders. Probucol, an antioxidant that lowers plasma cholesterol, has been shown to decrease smooth muscle cell proliferation and macrophage accumulation in blood vessels and to prevent restenosis after coronary angioplasty. We determined in 30-day-old male BDF1-pcy hybrid mice (derived from mating DBA/2FG-pcy and C57BL/6FG-pcy) the effect of probucol administered in the diet (1%) for 200 days on kidney weight relative to body weight (KW/BW), cyst expansion, renal interstitial fibrosis, and serum urea nitrogen (SUN) concentration. Animals were fed a moderately high-protein diet (HPD, 36%) to accentuate the development of renal cysts and to promote interstitial fibrosis. Probucol decreased serum cholesterol from 68 to 16 mg/dL but had no effect on food intake or body weight. Probucol decreased relative kidney size from 4.16% +/- 0.55% to 2.64% +/- 0.12% KW/BW (P < 0.01), SUN from 30.5 +/- 1.8 to 25.9 +/- 1.0 mg/dL (P < 0.05), cystic index from 2.45 +/- 0.11 to 1.36 +/- 0.10 (P < 0.01), and fibrosis index from 2.40 +/- 0.11 to 1.82 +/- 0.08 (P < 0.01). We conclude that probucol ameliorates the progressive deterioration in renal function and structure in pcy mice ingesting a relatively high level of dietary protein.

Abstract
The murine polycystic kidney disease gene, pcy, is an autosomal recessive trait located on chromosome 9. To determine the genetic locus of pcy, 222 intraspecific backcross mice were obtained by mating C57BL/6FG-pcy and Mus molossinus. Restriction fragment length polymorphism analysis of 70 of the 222 backcross progeny showed that pcy, dilute coat color (d), and cholecystokinin (Cck) were located in the order d--pcy--Cck from the centromere. Simple sequence repeat length polymorphism analysis of DNA of all 222 backcross mice was carried out using four markers which were located near the central regions of d and Cck. One and eight recombinations were detected between D9Mit24 and pcy and between D9Mit16 and pcy, respectively. However, no recombinant was observed among pcy, D9Mit14, and D9Mit148. These findings strongly suggest that D9Mit14 and D9Mit148 are located near the pcy gene and are good markers for chromosomal walking to this gene.
