In the present study, we characterized the gene product of open reading frame 3 encoded at human chromosome 20 (C20orf3), which represents a member of the lactonohydrolase super family. Multiple-tissue Northern blot analysis showed ubiquitous expression of the 2.4 kb transcript coding for 416 amino acids, with highest levels in human liver, placenta and kidney. After recombinant production of p...

Human bocavirus 1 (HBoV1) has been identified as one of the etiological agents of wheezing in young children with acute respiratory-tract infections. In this study, we have obtained the sequence of a full-length HBoV1 genome (including both termini) using viral DNA extracted from a nasopharyngeal aspirate of an infected patient, cloned the full-length HBoV1 genome, and demonstrated DNA replicat...

In this study we report the cloning of four human OCT1 (hOCT1/SLC22A1) isoforms: a long form, hOCT1G/L554, and three shorter forms (hOCT1G/L506, hOCT1G483 and hOCT1G353). All four variants could be identified in the human glioma cell line SK-MG-1, whereas only two isoforms (hOCT1G/L554 and hOCT1G/L506) were found in human liver cDNA. The hOCT1G/L554 represents the full length hOCT1 since the se...

objectives: long non-coding rnas (lncrnas), a vast class of recently discovered non-coding genes in the human genome, have been implicated in the regulation of several biological processes, including the maintenance of stem cell pluripotency and neurogenesis. new evidences have emerged that some long incrnas act as enhancers for their neighboring genes. oct4, also known as pou5f1 and oct3/4, fu...

K562 human leukemia cells synthesize embryonic hemoglobins after culture in the presence of hemin. We have rigorously identified these hemoglobins by globin chain analysis and peptide mapping. No adult hemoglobin could be detected, and beta-globin synthesis was less than 2 ppm of total protein synthesis. Persistent embryonic globin gene expression is known to occur as a consequence of globin ge...

background: prostate cancer is one of the leading causes of cancer deaths among men. new gene expressed in prostate (ngep), is a prostate-specific gene expressed only in normal prostate and prostate cancer tissue. because of its selective expression in prostate cancer cell surface, ngep is a potential immunotherapeutic target. to target the ngep in prostate cancer, it is essential to investigat...

We have studied a number of cell surface, enzyme, and protein markers in the human leukemic K562 cell line. We have confirmed previous observations that these cells accumulate human embryonic hemoglobins after exposure to hemin. In addition, our results demonstrated that these cells possess in the "ininduced" state i surface antigen, lactate dehydrogenase isoenzymes characteristic of embryonic ...

objective: mir-302-367 is a cluster of polycistronic micrornas that are exclusively expressed in embryonic stem (es) cells. the mir-302-367 promoter is functional during embryonic development but is turned off in later stages. motivated by the cancer stem cell hypothesis, we explored the potential expression of mir-302 in brain tumor cell lines. materials and methods: in the present experimenta...
