Germ cell nuclear factor (GCNF), a nuclear orphan receptor, involved in spermatogenesis, neurogenesis, differentiation, and embryo development, was highly expressed with two transcripts (7.4 and 2.3 kb) in mouse testis and with only one transcript (7.4 kb) slightly expressed in brain, liver, and kidney. The 2.3-kb transcript was restricted to round(More)
Sperm maturation during passage through the epididymis depends on regionalized gene expression which maintains the progressively changing environment within the epididymal tubule. Towards defining the genes that drive the sequential maturation of spermatozoa, we profiled regionally regulated gene expression pattern in the epididymis of a fertile young male(More)
Epididymal secreted proteins promote sperm maturation and fertilizing capacity by interacting with sperm during passage through the epididymis. Here we investigate the molecular basis of sperm maturation by isolating cDNA clones for novel epididymis-specific expressed sequences. Thirty-six novel cDNAs were isolated and sequenced from a subtracted Macaca(More)
Cystatin (CST)11, a novel member of the CST type 2 family of cysteine protease inhibitors, was identified in Macaca mulatta epididymis by subtractive hybridization cloning. The human CST11 gene on chromosome 20p11.2 is located near three other CST genes expressed predominantly in the male reproductive tract. The CST11 gene spans three exons, a structure(More)
BACKGROUND The lipocalin (LCN) family of structurally conserved hydrophobic ligand binding proteins is represented in all major taxonomic groups from prokaryotes to primates. The importance of lipocalins in reproduction and the similarity to known epididymal lipocalins prompted us to characterize the novel human epididymal LCN6. METHODS AND RESULTS LCN6(More)
Mammalian Gene Collection (MGC) verified over 9,000 human full-ORF genes and FLJ Program reported 21,243 cDNAs of which 14,409 were unique ones and 5,416 seemed to be protein-coding. The pity is that epididymis cDNA library was missing in their sequencing target list. Epididymis is a very important male accessory sex organ for sperm maturation and storage.(More)
CCAAT/enhancer-binding protein ␦ (C/EBP␦) is a nuclear transcription factor that regulates cellular growth and differentiation. In this study we demonstrate that C/EBP␦ gene expression is differentially regulated in rat androgen-dependent tissues and human prostate cancer. C/EBP␦ messenger RNA (mRNA) levels were very low in adult rat ventral prostate,(More)
A long and ever-expanding roster of small (∼20-30 nucleotides) RNAs has emerged during the last decade, and most can be subsumed under the three main headings of microRNAs (miRNAs), Piwi-interacting RNAs (piRNAs), and short interfering RNAs (siRNAs). Among the three categories, miRNAs is the most quickly expanded group. The most recent number of identified(More)
Beckman SW41 rotor. After centrifugation, gradient fractions (1 ml) were collected from the top for further analysis. As shown in Figure 1a, the DRM fraction appeared as an opalescent band in the low density fraction of the gradient (fraction No. 6). The total protein in each fraction also can be used as an indicator of appropriate fractionation. Figure 1b(More)
The α-(1,2) fucosyltransferases (Fut1 and Fut2) and α-(1,3) fucosyltransferases (Fut4, Fut9) are responsible for the synthesis of Lewis X (LeX) and Lewis Y (LeY) conjugated to glycoproteins. We recently reported that these fucosyltransferases were differentially expressed in the reproductive tract of male mouse. Here, we studied the effect of androgen on(More)
