Mitochonic acid-5 (MA-5), an indole-3-acetic acid derivative, improves mitochondrial dysfunction and has therapeutic potential against various diseases including kidney diseases. However, whether MA-5 is effective against peritoneal fibrosis remains unclear. Therefore, we investigated the effect of MA-5 using a peritoneal fibrosis mouse model. Peritoneal fibrosis was induced in C57BL/6 mice via intraperitoneal injection of chlorhexidine gluconate (CG) every other day for 3 weeks. MA-5 was administered daily by oral gavage. The mice were divided into control, MA-5, CG, and CG + MA-5 groups. Following treatment, immunohistochemical analyses were performed. Fibrotic thickening of the parietal peritoneum induced by CG was substantially attenuated by MA-5. The number of α-smooth muscle actin-positive myofibroblasts, transforming growth factor β-positive cells, F4/80-positive macrophages, monocyte chemotactic protein 1-positive cells, and 4-hydroxy-2-nonenal-positive cells was considerably decreased. In addition, reduced ATP5a1-positive and uncoupling protein 2-positive cells in the CG group were notably increased by MA-5. MA-5 may ameliorate peritoneal fibrosis by suppressing macrophage infiltration and oxidative stress, thus restoring mitochondrial function. Overall, MA-5 has therapeutic potential against peritoneal fibrosis.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39496475","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 investigated the function of the microRNA-98-3p (miR-98-3p)/Yin-Yang-1 (YY1) axis to the pathophysiological processes in PCOS mice. A mouse model of PCOS was established using dehydroepiandrosterone (DHEA). Hematoxylin and eosin (HE) staining was used to assess morphologic changes of the ovaries. Hormonal serum levels were measured by ELISA. Estrogen synthesis in OGCs was measured using chemiluminescence immunoassay. The viability, cell cycle, and apoptosis of ovarian granulosa cells (OGCs) were assessed by CCK-8, flow cytometry, and western blot. Luciferase reporter assays were conducted to examine the binding of miR-98-3p to YY1. YY1 was upregulated, while miR-98-3p was downregulated both in the ovarian tissues of PCOS mice and OGCs separated from PCOS mice and patients. YY1 Knockdown promoted OGC proliferation and inhibited apoptosis as well as increased estrogen production in OGCs. YY1 was verified to be targeted by miR-98-3p. Additionally, YY1 overexpression prevented the effects of miR-98-3p overexpression on the proliferation and apoptosis of OGCs. Importantly, miR-98-3p attenuated ovarian injury in PCOS mice. MiR-98-3p targets and downregulates YY1 expression, thereby affecting the proliferation and apoptosis of OGCs in PCOS.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39747851","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 encountered a novel parotid tumor containing numerous ghost cells and herein describe its histological features and discuss diagnostic problems. The patient was a 90-year-old Japanese male, who complained of swelling of the left parotid area for four months. Positron emission tomography indicated no cervical lymph node metastasis or distant metastasis. The tumor was successfully resected with no signs of recurrence or metastasis for six months after surgery. Histologically, the tumor was mainly composed of squamous cells forming irregularly shaped nests with a mixture of pleomorphic giant or multinucleated cells and bland basaloid cell. Keratinized areas were occupied by a prominent ghost cell population. Immunohistochemically, CK5/6 and CK19 were widely positive as well as AE1/AE3, p40 and p63. Nuclear expression of β-catenin was also observed. The present case can be regarded as a particular form of squamous cell carcinoma and is believed to contain a large number of ghost cells resulting from an unclear mechanism. However, it seems difficult to consider such tumors as a clinicopathologically independent entity at present. Applying a term such as \"salivary ghost cell carcinoma\" would be premature.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00795-021-00302-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39322508","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}
