In this study, we sought to identify food components with functional properties for the prevention and improvement of metabolic syndrome. We performed a luciferase reporter assay using fatty acid synthase (FAS) and low-density lipoprotein receptor (LDL) receptor gene promoters. Naturally occurring isothiocyanate sulforaphane impaired FAS promoter activity and reduced sterol regulatory element-binding protein (SREBP) target gene expression in human hepatoma Huh-7 cells. Sulforaphane reduced SREBP proteins by promoting the degradation of the SREBP precursor. Furthermore, we screened LDL receptor promoter effectors and observed that extract from sweet cherry peduncles induces LDL receptor gene promoter activity. Several analytical and chemical methods revealed that chrysin 7O-β-D-glucopyranoside in cherry peduncle extract stimulated LDL receptor gene promoter activity. Thus, this comprehensive search for components that alter the expression of genes associated with lipid metabolism led to the discovery of new functions of food components.","PeriodicalId":23810,"journal":{"name":"Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan","volume":"145 1","pages":"23-28"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932759","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}

Although these organoids show long-term proliferation, their hepatic functions remain low. Therefore, it is necessary to enhance the hepatic functions of primary human hepatocyte (PHH)-derived organoids. Here, we propose a novel method for two dimensional (2D)-cultured hepatic differentiation from PHH-derived organoids. PHH-derived organoids were established from cryopreserved PHHs. When cultured under a 2D condition, the single cells from PHH-derived organoids were seeded on collagen type I-coated plates. Then, optimal conditions for hepatic differentiation were screened using several compounds, cytokines and growth factors. Based on the results of the screening, we determined the 2D-cultured hepatic differentiation method from PHH-derived organoids. Hepatic gene expressions in PHH-derived organoids-derived hepatocytes (Org-HEPs) were greatly increased, compared to those in PHH-derived organoids. An RNA-seq analysis showed that gene expressions related to pharmacokinetics were upregulated in Org-HEPs compared to PHH-derived organoids. The metabolic activities of CYP1A2, CYP2C8, CYP2E1 and CYP3A4 were at levels comparable to those in PHHs. We also treated Org-HEPs and PHHs with hepatotoxic drugs, such as acetaminophen, troglitazone, amiodarone and clozapine. The cell viability of Org-HEPs was almost the same as that of PHHs. These results suggested that PHH-derived organoids could be differentiated into highly functional hepatocytes in 2D culture, and Org-HEPs could be used for hepatotoxicity tests. Thus, Org-HEPs will be useful for pharmaceutical research.","PeriodicalId":23810,"journal":{"name":"Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan","volume":"145 3","pages":"189-194"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143537828","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}

It mediates the transportation of nutrients, the exchange of gases such as oxygen and carbon dioxide, and the excretion of waste products between the fetus and mother. The surface of placental villi is covered by two layers of mononuclear undifferentiated cytotrophoblasts (CT) and multinucleated syncytiotrophoblasts (ST). The formation of the multinucleated ST layer via fusion of CT is referred to as syncytialization, which is a well-characterized morphological sign of terminal differentiation. STs function not only as the placental barrier to separate maternal blood from fetal tissue but also as the main source of human chorionic gonadotropin (hCG) and progesterone (P4) during pregnancy. The significance of appropriate differentiation and fusion of CTs to form STs is demonstrated by the finding that disturbance of these processes is linked to the pathogenesis of pregnancy-associated complications such as hypertensive disorders of pregnancy (HDP) and fetal growth restriction (FGR). In this review, we focused on trophoblast differentiation, cell fusion and microvilli formation, and showed the role of short-chain fatty acid butyrate and progesterone receptor membrane component 1 (PGRMC1) in these processes. Furthermore, we described the evaluation of placental function and its prospects utilizing a quantitative trophoblast cell fusion system and microfluidic device.","PeriodicalId":23810,"journal":{"name":"Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan","volume":"145 1","pages":"49-52"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932766","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}

Our concept of alveolar regeneration therapy is based on developing a drug delivery system (DDS) and dry powder inhalation that can efficiently deliver new alveolar regeneration drugs, which were discovered using human alveolar epithelial progenitor cells, to stem cells present on the surface of the alveoli of COPD patients, thereby inducing alveolar regeneration.

Among fatty liver diseases, those that are not caused by alcohol are referred to as nonalcoholic fatty liver disease (NAFLD). Some NAFLD can progress to nonalcoholic steatohepatitis (NASH), and further progression of NAFLD can lead to cirrhosis and liver cancer. Although numerous studies have demonstrated the efficacy of dietary polyunsaturated fatty acids (PUFAs), particularly omega-3 PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), against NAFLD, the detailed mechanisms by which these PUFAs exert their protective effects on the pathogenesis and progression of NAFLD are not well understood. Recent studies using knockout mouse models and genome-wide association studies have suggested a potential role for the enzymes responsible for the biosynthesis of PUFAs (FADS1, FADS2, ELOVL2, and ELOVL5) and their incorporation into phospholipids (LPCAT3/MBOAT5/LPLAT12 and LPIAT1/MBOAT7/LPLAT11) in the development of NAFLD.

T2DM, which accounts for approximately 90-95% of all diabetes mellitus cases, is caused by deficient insulin secretion, tissue insulin resistance, or both. Many therapeutic drugs for T2DM have been developed that target the pancreas, which secretes insulin. The liver is the central organ for glucose and lipid metabolism, and failure of hepatic regulatory mechanisms leads to hyperglycemia, insulin resistance, and lipid accumulation. Here, we focused on the liver as a novel therapeutic target for T2DM. The fatty acid composition of phospholipids, a major component of biological membranes, has received considerable research attention owing to their involvement in T2DM onset and progression. Fatty acids in phospholipids are cleaved by phospholipase A to form lysophospholipids, which are subsequently remodeled back into phospholipids by lysophospholipid acyltransferases (LPLATs). LPLATs play an important role in lipid metabolism and homeostasis by regulating the abundance of various phospholipid species in multiple cell and tissue types. We investigated whether overexpression of LPLAT10, also called LPCAT4 and LPEAT2, in the liver could improve abnormalities in glucose metabolism and help treat T2DM. For overexpression, we generated an LPLAT10-expressing adenovirus (Ad) vector using an improved Ad vector named Ad-E4-122aT, which exhibited higher and longer-term transgene expression and lower hepatotoxicity than conventional Ad vectors. In this article, we review the current findings that changes in hepatic phospholipid species due to liver-specific LPLAT10 overexpression affect the pancreas and suppress postprandial hyperglycemia by increasing postprandial insulin secretion.","PeriodicalId":23810,"journal":{"name":"Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan","volume":"145 3","pages":"171-176"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143537835","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}
