Uncontrolled self-renewal plays a direct function in the progression of different types of carcinomas. The same molecular pathway that manages self-renewal in normal stem cells also seems to manage cancer stem cells. Here, we examine the expressions of self-renewal regulatory factors Oct4, Nanog, Sox2, nucleostemin, Zfx, Esrrb, Tcl1, Tbx3, and Dppa4 in tissue samples of colon, prostate, and bla...

OBJECTIVE Endothelial progenitor cells (EPCs) have a potential application for cell therapy, however, their biological nature is not well-understood. EPCs also possess some stemness features, such as their clonogenicity and differentiation capacity. The main aim of this study was to evaluate the expression of certain transcription factors regulating selfrenewal property of stem cells. MATERIA...

With 10 segregating sites (simple nucleotide polymorphisms) in the last intron (1089 bp) of the ZFX gene we have observed 11 haplotypes in 336 chromosomes representing a worldwide array of 15 human populations. Two haplotypes representing 77% of all chromosomes were distributed almost evenly among four continents. Five of the remaining haplotypes were detected in Africa and 4 others were restri...

Korean long-tailed goral (Nemorhaedus caudatus) is one of the most endangered species in South Korea. However, detailed species distribution and sex ratio data on the elusive goral are still lacking due to difficulty of identification of the species and sex in the field. The primary aim of this study was to develop an economical PCR-RFLP method to identify species using invasive or non-invasive...

Zfy1 and Zfy2 are homologous zinc finger genes on the mouse Y Chromosome. To ask whether these genes are properly classified as members of the ZFY family, we have characterized and compared their genomic organization to that of mouse Zfx, human ZFX, and human ZFY. We show that Zfy1 has 11 exons distributed across at least 56 kb, and Zfy2 has a minimum of 9 exons distributed across at least 52 k...
