Fluorescence in situ hybridization (FISH) using PY3.4, X alpha satellite, and SRY probes was performed in each case to analyze the sex chromosome translocation and gene translocation. SRY gene was amplified by polymerase chain reaction (PCR) and its mutation was detected by direct sequencing. The results showed that among 8 patients, 5 were positive for SRY and the remaining negative for SRY. In the patients positive for SRY genes, 3 presented testes and the left 2 streak ovaries. In the patients negative for SRY, only one case presented testes, while 2 ovaries. Direct sequencing demonstrated that all SRY genes were normal in the patients positive for SRY genes. FISH technique demonstrated that SRY genes translocated from Ypter to Xpter in 2 46,XX phenotypic males positive for SRY genes. It was concluded that SRY gene is strongly involved in male sex determination, while a sequence of other genes may be taken into account in sexual development.展开更多

Data Sources： The data used in this review were mainly published in English from 2000 to present obtained from PubMed. The search terms were ＂SOX2,＂ ＂cancer,＂ ＂tumor＂ or ＂CSCs.＂ Study Selection： Articles studying the mitochondria-related pathologic mechanism and treatment of glaucoma were selected and reviewed. Results： SOX2, a transcription factor that is the key in maintaining pluripotent properties of stem cells, is a member of SRV-related high-mobility group domain proteins. SOX2 participates in many biological processes, such as modulation of cell proliferation, regulation of cell death signaling, cell apoptosis, and most importantly, tumor formation and development. Although SOX2 has been implicated in the biology of various tumors and CSCs, the findings are highly controversial, and information regarding the underlying mechanism remains limited. Moreover, the mechanism by which SOX2 involved in carcinogenesis and tumor progression is rather unclear yet. Conclusions： Here, we review the important biological functions of SOX2 in different tumors and CSCs, and the function of SOX2 signaling in the pathobiology ofneoplasia, such as Wnt/β-catenin signaling pathway, Hippo signaling pathway, Survivin signaling pathway, P13K/Akt signaling pathway, and so on. Targeting towards SOX2 may be an effective therapeutic strategy for cancer therapy.展开更多

Methods The mierodeletion of AZF was detected by multiplex polymerase chain reaction （PCR） using Y-chromosome specific sequence tagged sites （STSs）, and SRY was analyzed by PCR and sequencing. Results There were 100 cases with AZF microdeletion and the ratio of AZF microdeletion was 6.8% over all 1 474 cases. The ratios of AZF microdeletion of azoospermia group and severe oligozoospermia group were 9.0% and 7.1%, respectively, which was significantly different from oligozoospermia group （P〈 0. 05）. There were 67 cases with 5 STSs mierodeletion of sY152, sY239, sY243, sY254 and sY255. There were 20 cases with long fragment deletion more than 10 STSs, and the patterns of AZF microdeletion in other 13 cases were rare. In all 9 patients with disorders of sex differentiation, there were 6patients with SRY-absent and AZF-absent. There was no mutation of SRY gene by sequencing in other 3 patients with SRY-positive. Conclusion Deletions in AZF region of Y chromosome are specific with diagnoses with spermatogenesis disorder. Deletions of sY152, sY239, sY243, sY254 and sY255 occur the most frequently. SRY was an important candidate gene of testis-determining factor （TDF） gene.展开更多
