Although CD30 expression has been described mainly in hematopoietic tissues, several types of nonhematopoietic tumors including embryonic carcinoma and germ‐cell tumors express CD30. We examined CD30 distribution in the testis and epididymis from wild type and CD30‐deficient mice. In the testis, spermatogonia, spermatocytes and Sertoli cells expressed CD30, but not in spermatids. Spermatogonia and spermatocytes near the basement membrane strongly reacted to anti‐CD30. In the epididymis, CD30 expression was exclusively observed in luminal epithelia and some interstitial cells. Taken together, these results show a spatio‐temporal regulation of CD30 expression in mouse testis and epididymis and suggest a possible role of CD30 in spermatogonia and spermatocytes.","PeriodicalId":85060,"journal":{"name":"Korean journal of biological sciences","volume":"8 1","pages":"197 - 203"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12265071.2004.9647751","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59656495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, administration of anti‐4–1BB mAb induced inhibition of melanoma metastasis. Agonistic anti‐4–1 BB mAb induced not only CD8+4–1BB+ T cells but also CD8+IFN‐γ+ T cell population. In the presence of anti‐CD3 antibody, lymphocytes produced high levels of IFN‐γ and low levels of IL‐4 in anti‐4–1 BB mAb treated group. Exposure of melanoma cells to IFN‐γ induced expression of MHC‐I molecules. Thus, the increase in number of CD8+ T cells and enhanced MHC‐I expression on B16F10 cells by augmented IFN‐γ production in response to anti‐4–1 BB mAb may result in suppression of tumor growth and metastasis.","PeriodicalId":85060,"journal":{"name":"Korean journal of biological sciences","volume":"8 1","pages":"117 - 123"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12265071.2004.9647743","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59656533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we carried out site‐directed mutagenesis of 6 conserved amino acids (Cys224, Gln231, Asp296, His457, His465, and Asp482) in Cys box, QQD box, and His box. Interestingly, the conserved Gln 231 was not essential for the catalytic activity of mHAUSP. However, the other conserved amino acids were required for deubiquitinating activity of mHAUSP.

The three inbred lines showed significant differences in their responses to intruder mice. Three factors, accounting for about 68% of the total variance, were extracted from the scores obtained from the three behavioral tests. The first two major factors are primarily associated with the anxiety‐related behaviors. One includes anxiety behaviors with a locomotive basis, while the other includes defecation measured in both anxiety tests. The third factor explains the three social behaviors, facial investigation, ano‐genital investigation, and following, observed in the resident intruder test, although facial investigation is also moderately associated with the second factor.
