Abstract
Y chromosome microdeletions are the second most common genetic cause of male infertility after Klinefelter syndrome. The aim of this study was to determine the patterns of Y chromosome microdeletions among infertile Mongolian men. A descriptive study was performed on 75 infertile men from February 2017 to December 2018. Y chromosome microdeletions were identified by polymerase chain reaction. Semen parameters, hormonal levels, and testis biopsy samples were examined. Among 75 infertile men, two cases of Y chromosome microdeletions were identified. The first case had an AZFa complete deletion and the other had an AZFc partial deletion. This study found that the proportion of Y chromosome microdeletions among infertile Mongolian men was 2.66%. The findings can be applied to in vitro fertilization and assisted reproductive technology, and our results will help clinicians improve treatment management for infertile Mongolian couples.

Abstract
Peroxidasin (PXDN) has been reported to crosslink the C-terminal non-collagenous domains of collagen IV (Col IV) by forming covalent sulfilimine bond. Here, we explored the physiological role of PXDN and its mechanism of action in endothelial cell survival and growth. Silencing of PXDN using siRNAs decreased cell proliferation without increase of the number of detached cells and decreased cell viability under serum-starved condition with increased fragmented nuclei and caspase 3/7 activity. Conditioned medium (CM) containing wild-type PXDN restored the proliferation of PXDN-depleted cells, but CM containing mutant PXDN with deletion of either N-terminal extracellular matrix (ECM) motifs or peroxidase domain failed to restore PXDN function. Accordingly, anti-PXDN antibody [raised against IgC2 (3-4) subdomain within ECM motifs] and peroxidase inhibitor phloroglucinol prevented the rescue of the PXDN-depleted cells by PXDN-containing CM. PXDN depletion resulted in loss of sulfilimine crosslinks, and decreased dense fibrillar network assembly of not only Col IV, but also fibronectin and laminin like in Col IV knockdown. Exogenous PXDN-containing CM restored ECM assembly as well as proliferation of PXDN-depleted cells. Accordingly, purified recombinant PXDN protein restored the proliferation and ECM assembly, and prevented cell death of the PXDN-depleted cells. PXDN depletion also showed reduced growth factors-induced phosphorylation of FAK and ERK1/2. In addition, siPXDN-transfected cell-derived matrix failed to provide full ECM-mediated activation of FAK and ERK1/2. These results indicate that both the ECM motifs and peroxidase activity are essential for the cellular function of PXDN and that PXDN is crucial for ECM assembly for survival and growth signaling.

Abstract
Abstract
The recombinant kringle domain of urokinase-type plasminogen activator (UK1) has been shown to inhibit angiogenesis in vitro and in vivo and suppress brain tumor in vivo. To avoid limitations in application due to mass production of recombinant proteins, we dissected UK1 sequences to seven peptides based on structure and amino acid characteristics, and examined the anti-angiogenic activities for the constructed peptides. UP-7 peptide derived from ß-sheets region of UK1 was the most potent inhibitor of the proliferation and migration of endothelial cells (ECs) in vitro, and it also inhibited in vivo angiogenesis in the mouse matrigel plug assay. Such anti-angiogenic activities were not exerted by the scrambled peptide. At molecular level, UP-7 inhibited the VEGF or bFGF-induced phosphorylation of FAK and ERK1/2 and suppressed formation of stress fibers and focal adhesions. It also inhibited the attachment and spreading of ECs onto immobilized fibronectin. In a lung cancer animal model xenografted with UP-7-non-sensitive NCI H460, systemic treatment of UP-7 effectively suppressed tumor growth through inhibition of angiogenesis. Interestingly, breast cancer cells such as MDA-MB231 were sensitive to UP-7 in proliferation differently from other cancer cells. It inhibited the migration and invasion of LM-2-MDA-MD231 and suppressed the phosphorylation of FAK. Accordingly, UP-7 potently inhibited lung metastatic growth of LM2-MDA-MB-231 in experimental metastasis model. Taken together, these results suggest that novel UK1-derived peptide, UP-7 can be effectively used for treatment of the metastatic growth of breast cancer.

Abstract
Abstract
The recombinant kringle domain of urokinase-type plasminogen activator (UK1) has been shown to inhibit angiogenesis in vitro and in vivo and suppress brain tumor in vivo. UK1 consists of 83 amino acids and has 2 short helices, rudimentary ß-sheets and one extended antiparallel ß-sheets regions. In order to identify functional core sequence of the UK1 for angiogenesis inhibition, we examined the anti-angiogenic and anti-tumor activities for the seven UK1-derived peptides. Among the tested peptides, UP-7 potently inhibited the proliferation and migration of endothelial cells in vitro and suppressed vessel formation in Matrigel plugs in vivo. However, such anti-angiogenic activities were not exerted by the scrambled peptide UP7-SC7 or UP7-derived shorter peptides. UP-7 also suppressed VEGF-induced phosphorylation of FAK and ERK1/2 in endothelial cells. In a NCI-H460 lung cancer xenografted animal model, UP-7 effectively inhibited tumor growth. In addition, treatment of mice bearing MDA-MB231 tumor with UP-7 peptide resulted in a dose-dependent inhibition of tumor growth. Taken together, these results suggest that UK1- derived novel peptide UP-7 can be used for treatment of cancers. (NRF-2012R1A1A2007175).

Abstract
BACKGROUND Dimeric human erythropoietin (dHuEPO) peptides are reported to exhibit significantly higher biological activity than the monomeric form of recombinant EPO. The objective of this study was to produce transgenic (tg) mice expressing dHuEPO and to investigate the characteristics of these mice. METHODS A dHuEPO-expressing vector under the control of the goat beta-casein promoter, which produced a dimer of human EPO molecules linked by a 2-amino acid peptide linker (Asp-Ile), was constructed and injected into 1-cell fertilized embryos by microinjection. Mice were screened using genomic DNA samples obtained from tail biopsies. Blood samples were obtained by heart puncture using heparinized tubes, and hematologic parameters were assessed. Using the microarray analysis tool, we analyzed differences in gene expression in the spleens of tg and control mice. RESULTS A high rate of spontaneous abortion or death of the offspring was observed in the recipients of dHuEPO embryos. We obtained 3 founder lines (#4, #11, and #47) of tg mice expressing the dHuEPO gene. However, only one founder line showed stable germline integration and transmission, subsequently establishing the only transgenic line (#11). We obtained 2 F1 mice and 3 F2 mice from line #11. The dHuEPO protein could not be obtained because of repeated spontaneous abortions in the tg mice. Tg mice exhibited symptoms such as short lifespan and abnormal blood composition. The red blood cell count, white blood cell count, and hematocrit levels in the tg mice were remarkably higher than those in the control mice. The spleens of the tg mice (F1 and F2 females) were 11- and -21-fold larger than those of the control mice. Microarray analysis revealed 2,672 spleen-derived candidate genes; more genes were downregulated than upregulated (849/764). Reverse transcriptase-polymerase chain reaction (RT-PCR) and quantitative real-time PCR (qRT-PCR) were used for validating the results of the microarray analysis of mRNA expression. CONCLUSIONS In conclusion, dHuEPO tg mice caused excessive erythrocytosis that led to abnormal blood composition, short lifespan, and abnormal splenomegaly. Further, we identified 2,672 genes associated with splenomegaly by microarray analysis. These results could be useful in the development of dHuEPO-producing tg animals.

Abstract
This study was conducted to characterize and functionally analyze the monkey 20α-hydroxysteroid dehydrogenase (20α-HSD) in the ovary, placenta, and oviduct. We focused on 20α-HSD mRNA expression and protein localization in monkey reproductive tissues and the molecular characterization of the promoter region. Reverse transcription-polymerase chain reaction (RT-PCR) monkey 20α-HSD mRNA was more strongly detected in the ovary at pre-ovulation than in the placenta and oviduct at pre-parturition. The mRNA was approximately 1.2kb in size and the expression was high in the ovary, which was the same as the RT-PCR result. We also produced His tagged 20α-HSD proteins by using an Escherichia coli expression system. In a western blot for the 20α-HSD protein, only 1 band of approximately 37-kDa was detected in the ovary, oviduct tissue, and recombinant protein produced in the Chinese hamster ovary (CHO) cell line. However, in the placenta, additional 2 bands (35 and 39 kDa) were detected. Immunohistochemical analyses suggested that the monkey 20α-HSD protein was localized mainly in the syncytiotrophoblast of the placenta and the isthmus cells of the oviduct. According to promoter analyses with the enhanced green fluorescent protein (EGFP) gene, the monkey 20α-HSD promoter was efficiently expressed in the CHO-K1 cell line; however, the promoter was not expressed in bovine fetal fibroblast (bFF) cell. Taken together, our study showed that the 20α-HSD mRNA and protein are coordinately expressed in the ovary at pre-ovulation and in the placenta and oviduct at pre-parturition. Therefore, monkey 20α-HSD in the placenta, ovary and oviduct plays an important role in the estrous cycle, pregnancy, and parturition.

Abstract
BACKGROUND The aldo-keto reductase family 1 member C1 (AKR1C1) belongs to a superfamily of NADPH-dependent reductases that convert a wide range of substrates, including carbohydrates, steroid hormones, and endogenous prostaglandins. The 20 alpha-hydroxysteroid dehydrogenase (20 alpha-HSD) is a member of AKR family. The aims of this study were to determine its expression in the ovary and uterus endometrium during the estrous cycle and pregnancy. METHODS Rapid amplification of cDNA ends (RACE) experiments were performed to obtain the 5' and 3' ends of the porcine 20 alpha-HSD cDNA. Reverse-transcriptase-PCR (RT-PCR), real-time PCR, northern blot analysis, and western blot analysis were performed to examine the expression of porcine 20 alpha-HSD. Immunohistochemical analysis was also performed to determine the localization in the ovary. RESULTS The porcine 20 alpha-HSD cDNA is 957 bp in length and encodes a protein of 319 amino acids. The cloned cDNA was virtually the same as the porcine AKR1C1 gene (337 amino acids) reported recently, and only differed in the C-terminal region (the AKR1C1 gene has a longer C-terminal region than our sequence). The 20 alpha-HSD gene (from now on referred to as AKR1C1) cloned in this paper encodes a deletion of 4 amino acids, compared with the C-terminal region of AKR1C1 genes from other animals. Porcine AKR1C1 mRNA was expressed on day 5, 10, 12, 15 of the cycle and 0-60 of pregnancy in the ovary. The mRNA was also specifically detected in the uterine endometrium on day 30 of pregnancy. Western blot analysis indicated that the pattern of AKR1C1 protein in the ovary during the estrous cycle and uterus during early pregnancy was similar to that of AKR1C1 mRNA expression. The recombinant protein produced in CHO cells was detected at approximately 37 kDa. Immunohistochemical analysis also revealed that pig AKR1C1 protein was localized in the large luteal cells in the early stages of the estrous cycle and before parturition. CONCLUSIONS Our study demonstrated that AKR1C1 mRNA and protein are coordinately expressed in the luteal cell of ovary throughout the estrous cycle and in the uterus on day 30 of pregnancy. Thus, the porcine AKR1C1 gene might control important mechanisms during the estrous cycle.

Abstract
The enzyme 20α-hydroxysteroid dehydrogenase (20α-HSD) catalyzes the conversion of progesterone to its inactive form, 20α-hydroxyprogesterone. This enzyme plays a critical role in the regulation of luteal function in female mammals. In this study, we conducted the characterization and functional analyses of bovine 20α-HSD from placental and ovarian tissues. The nucleotide sequence of bovine 20α-HSD showed significant homology to that of goats (96%), humans (84%), rabbits (83%), and mice (81%). The mRNA levels increased gradually throughout the estrous cycle, the highest being in the corpus luteum (CL) 1 stage. Northern blot analysis revealed a 1.2 kb mRNA in the bovine placental and ovarian tissues. An antibody specific to bovine 20α-HSD was generated in a rabbit immunized with the purified, recombinant protein. Recombinant 20α-HSD protein produced in mammalian cells had a molecular weight of ∼37 kDa. Bacterially expressed bovine 20α-HSD protein showed enzymatic activity. The expression pattern of the 20α-HSD protein in the pre-parturition placenta and the CL1 stage of the estrous cycle was similar to the level of 20α-HSD mRNA expression. Immunohistochemical analysis also revealed that bovine 20α-HSD protein was intensively localized in the large luteal cells during the late estrous cycle.
