CD25FOXP3CD45RA regulatory T-cell infiltration as a prognostic biomarker for endometrial carcinoma.

Background: Regulatory T (Treg) cells reportedly play crucial roles in tumor angiogenesis as well as antitumor immunity. In order to explore their therapeutic potential, we investigated the precise prognostic impact of Treg markers in endometrial carcinoma.

Methods: We performed multiplexed immunofluorescence and quantitative image analyses of CD25, FOXP3, CTLA4, and CD45RA in tumor specimens from 176 consecutive patients treated at our institution for primary endometrial carcinomas.

Preoperative Venous Thromboembolism Screening and Postoperative Selective Anticoagulant Therapy Effectively Prevents Postoperative Symptomatic Venous Thromboembolism in Gynecological Malignancies: A 15-Year, Single-Center Study.

The aim of this study was to determine which type of prophylaxis was effective for postoperative symptomatic venous thromboembolism (VTE) in patients with gynecological malignancies. A total of 1756 consecutive patients undergoing laparotomy as first-line treatment were included. In Period 1 (2004-2009), low-molecular weight heparin (LMWH) was not available for postoperative VTE prophylaxis, but available in after Period 2 (2009-2013).

Differential roles of the Wip1-p38-p53 DNA damage response pathway in early/advanced-stage ovarian clear cell carcinomas.

Background: Ovarian clear cell carcinoma (OCCC) is one of the most lethal types of ovarian cancer. Early-stage OCCC can be cured by surgery; however, advanced-stage disease shows poor prognosis due to chemoresistance unlike the more common high-grade serous carcinoma.

Methods: We explored the differential roles of the Wip1-p38-p53 DNA damage response pathway in respective early- or advanced-stage OCCC by immunohistochemistry of Wip1, phospho-p38, p53, and phospho-p53 from consecutive 143 patients.

Daam1 regulates the endocytosis of EphB during the convergent extension of the zebrafish notochord.

Convergent extension (CE) movement of cells is one of the fundamental processes that control the organized morphogenesis of tissues and organs. The molecular events connecting the noncanonical Wnt pathway and CE movement, however, are not well understood. We show that subcellular localization of Daam1, an essential component of noncanonical Wnt signaling, changes dynamically during notochord formation.

Binding of AlF-C, an Orc1-binding transcriptional regulator, enhances replicator activity of the rat aldolase B origin.

A region encompassing the rat aldolase B gene (aldB) promoter acts as a chromosomal origin of DNA replication (origin) in rat aldolase B-nonexpressing hepatoma cells. To examine replicator function of the aldB origin, we constructed recombinant mouse cell lines in which the rat aldB origin and the mutant derivatives were inserted into the same position at the mouse chromosome 8 by cre-mediated recombination. Nascent strand abundance assays revealed that the rat origin acts as a replicator at the ectopic mouse locus.
