However, the correlation between these stromal reactions and cervical adenocarcinoma has been poorly documented. This investigation elucidated whether DR is a prognostic indicator in early cervical adenocarcinoma patients. Fifty-nine patients with early stage cervical adenocarcinoma (stages I/II) were included in the study. DR was divided into three groups, mature, intermediate, and immature, based on the presence of myxoid stroma and hyalinized keloid-like collagen. Inflammatory cell responses were classified as mild, moderate, and severe. Those stromal reactions were separately evaluated in the invasion front stroma and intratumoral stroma. In both the intratumor and invasion front stroma, intermediate/immature DR was correlated with tumor size, T stage, N stage, lymphovascular invasion, and parametrial infiltration (p < 0.001 to p < 0.05). In addition, in the intratumoral stroma, intermediate/immature DR led to short relapse-free survival and overall survival (p < 0.001). In the invasion front stroma, inflammatory cell responses were associated with DR immaturity and FIGO stage (p < 0.01). These results suggest that the classification of DR maturity is a potential prognostic biomarker in early stage cervical adenocarcinoma patients. DR can be evaluated by routine H&E staining without immunohistochemistry, making it convenient and economical in clinical practice.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":"55 4","pages":"275-282"},"PeriodicalIF":1.8,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40623926","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}

Glucocorticoid receptor beta (GRβ) acts as an inhibitor of GR; however, its function is not well understood. Serum- and glucocorticoid-regulated kinase 1 (SGK1) is a GR-responsive gene that phosphorylates N-myc downstream-regulated gene 1 (NDRG1) and is involved in cancer growth and invasion. However, the expression of GR, GRβ, SGK1, and NDRG1 in prostate cancer and their relationship with clinicopathological and functional significance remain unknown. The association between the status of GR, GRβ, SGK1, and NDRG1 immunoreactivity and clinicopathological variables was analyzed in patients with prostate carcinoma to explore their clinical significance. In prostate carcinoma cases, the relative abundance of GR and NDRG1 immunoreactivity was inversely and significantly associated with the primary tumor stage (pT), while GR immunoreactivity was inversely and significantly associated with the Ki-67 score. The relative expression status of NDRG1 was significantly associated with that of GR.

In both cases, several cells with frosted nuclei were observed, and the cytological findings per 100 cells were evaluated. The infected cells were mononuclear to multinuclear, showing chromatin aggregation at the nuclear margins, intranuclear inclusion bodies, eosinophilic cytoplasmic inclusion bodies, and mutual pressure exclusion of the nuclei. Immunocytochemical staining revealed that the cells were positive for AE1/AE3 and negative for CD68 expression, indicating their epithelial origin. Furthermore, infected cells with frosted nuclei were positive for surfactant protein A (SP-A) in Case 2, suggesting infection of type II alveolar pneumocytes or Clara cells. Moreover, in Case 2, the infected cells were positive for herpes simplex virus (HSV) I + II and SARS-CoV-2 spike protein, confirming double infection in these cells.

In this study, IDC-NST, ductal carcinoma in situ (DCIS), atypical ductal hyperplasia (ADH), and non-pathological breast tissues were all evaluated by immunohistochemistry.

MR in progesterone receptor (PR)-positive IDC-NST cases tended to be associated with the Ki-67 labeling index. Results of the present study demonstrated that the status of MR and GR in conjunction with the 11βHSDs was correlated with the development of low-grade proliferative disorders in mammary glands.

We examined the preservation effects of our supercooling preservation technique in a rat model of artery transplantation. Our technique produces a supercooled state at - 2 °C with application of 1000 V. The viability of tissue cells from rat arteries was found to be higher with storage using the proposed method than that under ordinary conditions. Damage to the vascular endothelium of the femoral artery preserved by voltage-applied supercooling at - 2 °C was reduced compared to storage under ordinary conditions. Artery graft revival was successfully achieved with graft patency after supercooling preservation, and 1 week outcomes for post-transplanted grafts, including thrombosis, were better with supercooling preservation than with conventional 4 °C preservation.

In this study, embryonic rat livers were obtained to examine the expression of fascin and fibronectin during liver development. Then, the effect of fibronectin on fascin expression was investigated. At embryonic day (ED) 10.5, when the foregut endoderm began to form the liver bud and spread into the septum transversum, fibrous extracellular matrix was observed between the space where the liver bud and the septum transversum merged. At ED11.5, fibronectin was observed surrounding the cluster of fascin-positive hepatoblasts. At ED13.5, hematopoietic cells emerged and both fibronectin and fascin expression started to decline. Fascin and fibronectin appeared temporarily and disappeared by ED 14.5. Their expression was chronologically synchronized. Subsequently, the effect of fibronectin on fascin was examined by cultivation of hepatoblasts that were isolated from the ED13.5 rat liver. As a result, with fibronectin, fascin was positive in most hepatoblasts, although, without fibronectin, fascin expression was remarkably declined. Presently, there are few studies about the relationship between fascin and fibronectin.

To date, it is suggested that the aberrant microRNA (miRNA) expressions play important roles in the pathogenesis of endometriosis. Reviewing the literature, we found nine overexpressed miRNAs, which were thoroughly investigated in the context of endometriotic tissues and cells. Most of the overexpressed miRNAs induced endometriosis-specific characteristics including inhibition of apoptosis and decidualization, upregulation of fibrogenesis, invasion, migration, cell proliferation, attachment to extracellular matrix, inflammation, and angiogenesis in the endometriotic cells. Then, we found that the downstream target molecules of these miRNAs, such as early growth response protein-1, extracellular signal-regulated kinase, matrix metallopeptidase 1, signal transducer and activator of transcription 3, cyclooxygenase-2, phosphoinositide 3-kinase, AKT, mammalian target of rapamycin, and vascular endothelial growth factor-A are promising for the therapeutic targets of endometriosis. Recent findings suggest that complex molecular mechanisms leading to development and progression of endometriosis by miRNAs may exist in endometriosis. The meticulous balance between tumorigenic miRNAs and tumoristatic miRNAs may destine the natural course and response to the surgical, medical, and hormonal treatments of this disease. Further investigations into endometriosis-associated miRNAs may elucidate the pathogenesis of endometriosis and help to develop novel therapeutics.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":"55 2","pages":"85-90"},"PeriodicalIF":1.2,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39931383","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}
