The mRNA expression of zinc transporters, such as Slc39a (Zip) 4, Zip5, Zip10, and Slc30a (ZnT) 1, in various tissues (liver, kidney, and duodenum) quickly responded to dietary zinc deficiency. Although there was no significant difference in serum calcium concentrations between the PF and ZD groups, serum 1,25-dihydroxycholecalciferol (1,25(OH)2D3) was higher in the ZD group than in the PF group. Moreover, short-term zinc deficiency significantly increased mRNA expression of transient receptor potential (TRP) cation channel subfamily vanilloid (V) member 6, S100 calcium binding protein G (S100g), and ATPase plasma membrane Ca2+ transporting 1 (Atp2b1) in the duodenum. Furthermore, short-term zinc deficiency increased vitamin D receptor (VDR) and cytochrome P450 family 24 subfamily A member 1 (Cyp24a1) mRNA expression in the kidney. These findings suggested that short-term zinc deficiency maintains serum calcium concentrations through Ca absorption-related gene expression in the duodenum, and that short-term zinc deficiency induced the expression of Cyp24a1 in kidney in response to an increase in the serum 1,25(OH)2D3 level.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 1","pages":"82-87"},"PeriodicalIF":1.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139990353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its upregulation in the brain can effectively prevent and treat central nervous system (CNS) diseases, including depression, Alzheimer's disease (AD), and Parkinson's disease (PD). BDNF is synthesized in various peripheral tissues as well as in the brain and can be transported from peripheral circulation into the brain through the blood-brain barrier. Therefore, foods that upregulate BDNF in peripheral tissues may be beneficial in preventing and treating these CNS diseases. Previously, we revealed that treatment with Chinpi (Citrus unshiu peel) and Citrus natsudaidai increased BDNF levels in the human renal adenocarcinoma cell line ACHN. Here, we evaluated the effects of 21 citrus cultivars on BDNF production in ACHN cells by measuring BDNF levels in the cell culture medium. We found that treatment with peels and pulps of 13 citrus varieties increased BDNF levels in ACHN cells. Treatment with Aurantium, Acrumen, and their hybrids citrus varieties showed a potent BDNF-upregulating effect but not with varieties belonging to Limonellus, Citrophorum, and Cephalocitrus. In addition, treatment with some of those Acrumen and its hybrid citrus species resulted in elevated levels of BDNF transcripts in ACHN cells. These results suggest that peels of many citrus cultivars contain ingredients with a potential BDNF-upregulating ability, which may be novel drug seeds for treating depression, AD, and PD. Furthermore, many citrus cultivars could be used as BDNF-upregulating foods.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 1","pages":"61-71"},"PeriodicalIF":1.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139990380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether FOS enhances the expression of genes in other pathways, particularly the non-inflammatory pathways, in Caco-2 cells has not been investigated. Here, we explored the pathways affected by FOS, based on identification of differentially expressed genes with ≥2-fold change (linear-fold change) in expression upon FOS treatment. Caco-2 cells were cultured for 24 h in high glucose-Dulbecco's modified Eagle medium supplemented with 10% fetal calf serum containing FOS. The differentially expressed genes in these cells, identified using mRNA microarray analysis, were categorized using the pathway analysis and subsequently upregulated genes in typical pathways were subjected to protein network analysis. RT-qPCR was performed to validate the expression of selected genes. Treatment with 10% FOS enhanced the expression of a set of genes, such as ITGB8, ITGA6, SPP1, CAV1, LAMA3, ARHGAP5, and LAMC2, in the focal adhesion pathway. In addition, this treatment increased the expression of many genes involved in various inflammatory pathways, such as TNF, ITGA5, ITGB3, PTGS2, FGF2, FLNC, EDNRB, VEGFA, and MMP13. Protein network analysis showed that genes in the focal adhesion and endothelin pathways induced by FOS were closely associated with each other.

This survey was conducted between 18-20 December 2019 using a self-administered web-based questionnaire. The participants were recruited from panel members of an online survey company. A total of 1,200 adults living in the five Japanese prefectures with the highest predicted food shortages after the anticipated Nankai Trough earthquake, took part in the study. Multivariable logistic regression analyses revealed a significant positive relationship between disaster knowledge level and beginning food stockpiling (p for trend <0.001). Compared with those who had a low level of disaster knowledge, participants who had a medium level of knowledge were 2.11 times more likely to begin stockpiling food (adjusted odds ratio [OR]: 2.11, 95% confidence intervals [CI]: 1.49-2.97), whereas those with the highest knowledge level were 2.52 times more likely to begin stockpiling food (adjusted OR: 2.52, 95% CI: 1.79-3.56). Beginning food stockpiling can be the first step toward disaster preparedness. It is considered that people with low disaster knowledge levels are more likely to have no beginning food stockpiling and are at high risk for disasters. These findings suggest ways to approach prioritizing people facing high disaster risk.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 5","pages":"422-429"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142546017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, however, no study has examined the association between antioxidant vitamin intake and LOX-index, a predictive biomarker of cardiovascular disease. We investigated the cross-sectional association between antioxidant vitamin (α-carotene, β-carotene, α-tocopherol, and vitamin C) intake and LOX-index in Japanese municipal workers. Participants were 346 workers (171 men and 175 women aged 19-71 y) who received a health check-up and participated in a nutrition and health survey. Antioxidant vitamin intake was assessed using a validated brief self-administered diet history questionnaire. LOX-index was calculated by multiplying serum concentrations of the soluble form of lectin-like oxidized LDL receptor 1 by those of LOX-1 ligands containing apolipoprotein B. Multiple regression analysis was used to estimate the geometric mean of LOX-index according to tertile of each antioxidant vitamin intake. Overall, α-carotene, β-carotene, α-tocopherol, and vitamin C intake were not associated with LOX-index. However, in stratified analyses by sex, geometric means of LOX-index tended to decrease with antioxidant vitamin intake in women, but not in men. The geometric means of LOX-index for the lowest through highest tertile of α-carotene intake were 771 (604-984), 639 (511-799), and 564 (469-677) (p for trend=0.07).

Paternal zinc deficiency can lead to developmental programming effects on the offspring's zinc homeostasis. This study investigated the effects of paternal zinc deficiency on the zinc homeostasis of offspring in a Drosophila melanogaster (fruit fly) model. Male flies were reared on a diet supplemented with a zinc-chelator, N,N,N',N'-Tetrakis(2-pyridylmethyl)ethylenediamine (TPEN), from the egg stage until adulthood, and their offspring were subsequently reared on a normal diet for 7 d. Body zinc status and zinc transporters were assessed afterwards. The results indicated that the prenatal zinc deficiency significantly lowered total body zinc levels (p<0.05) compared to the controls. Additionally, the mRNA levels of zinc transporters, dZip42C.1, dZnT63C, and dZnT35C, were lower in the zinc-deficient male parents (p<0.05) and their male offspring (p<0.05). These findings suggested that paternal zinc deficiency can alter offspring zinc homeostasis, even when the offspring was fed a zinc-sufficient diet. This is an important finding, as zinc is an essential nutrient that is required for a variety of bodily functions. Further research is needed to better understand the mechanisms by which zinc deficiency in the male parent affects the health of the offspring and to develop strategies to prevent this from happening.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"70 6","pages":"462-469"},"PeriodicalIF":0.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated gene expression in adipose tissue, as well as short-chain fatty acids (SCFAs) levels and microbial composition in the cecum contents. 1-Kestose intake restored the increased relative abundance of tumor necrosis factor (Tnf) mRNA in adipose tissue and the reduced level of butyrate in the cecum contents of HFD-fed rats to those observed in control diet-fed rats. Additionally, 1-kestose consumption changed the composition of the gut microbiota, increasing Butyricicoccus spp., decreasing UGC-005 and Streptococcus spp., in the cecum contents of HFD-fed rats.

Given that mouse offspring derived from mothers fed a LAhigh/ALAlow diet during gestation and early lactation showed increased anxiety-related behaviors and that rodents exposed to a LAhigh/ALAlow diet are more vulnerable to stress, in this study, we investigated the effects of maternal LAhigh/ALAlow diet consumption on stress-induced anxiety-related behavior and the brain structures involved in the expression of negative emotional states in mouse offspring. In a standard environment, offspring exposed to either the control diet or the LAhigh/ALAlow diet in utero showed similar stay times in the center zone in the open field test. On the other hand, under stressful environments, offspring exposed to the LAhigh/ALAlow diet in utero showed decreased stay times in the center zone compared to those exposed to the control diet. We further found that the number of a subpopulation of pyramidal neurons in the basolateral amygdala, which can regulate negative emotional behaviors, was greater in the offspring exposed to the LAhigh/ALAlow diet compared to those exposed to the control diet.
