Glypican-1 (GPC1) protein in exosomes was recently identified as a biomarker for the early detection of pancreatic ductal adenocarcinoma (PDAC). Immunohistochemical analyses and in vitro assays were conducted to assess the usefulness of GPC1 as a PDAC biomarker, to reveal the biological role of GPC1 in pancreatic carcinogenesis, and to ascertain the regulation mechanism of GPC1. An aberrant ove...

Nasopharyngeal carcinoma (NPC) is a head and neck cancer with high incidence in South China and East Asia. To provide a theoretical basis for NPC risk screening and early prevention, we conducted a meta-analysis of relevant literature on the association of single nucleotide polymorphisms (SNP)s with NPC susceptibility. Further, expression of 15 candidate SNPs identified in the meta-analysis was...

These studies build on 2 prior observations, that exposure of CB-derived CD34 cells to UM171 leads to a rapid induction of EPCR expression both at the messenger RNA and protein levels and that EPCR expression can be used to identify murine HSCs, the latter finding suggesting that EPCR may be used similarly in the human setting. Identifying methods to quickly assess expansion of human HSCs ex vi...

Ecotropic viral integration site 1 (EVI1) is an oncogenic dual domain zinc finger transcription factor that plays an essential role in the regulation of hematopoietic stem cell renewal, and its overexpression in myeloid leukemia and epithelial cancers is associated with poor patient survival. Despite the discovery of EVI1 in 1988 and its emerging role as a dominant oncogene in various types of ...

MicroRNA-9 (miR-9) is emerging as a critical regulator of organ development and neurogenesis. It is also deregulated in several types of solid tumors; however, its role in hematopoiesis and leukemogenesis is not yet known. Here we show that miR-9 is detected in hematopoietic stem cells and hematopoietic progenitor cells, and that its expression increases during hematopoietic differentiation. Ec...

Inv(3)(q21q26)/t(3;3)(q21;q26) is recognized as a distinctive entity of acute myeloid leukemia (AML) with recurrent genetic abnormalities of prognostic significance. It occurs in 1-2.5% of AML and is also observed in myelodysplastic syndromes and in the blastic phase of chronic myeloid leukemia. The molecular consequence of the inv(3)/t(3;3) rearrangements is the juxtaposition of the ribophorin...

The development of novel technologies, such as massively parallel DNA sequencing, has led to the identification of several novel recurrent gene mutations, such as DNA methyltransferase (Dnmt)3a, ten-eleven-translocation oncogene family member 2 (TET2), isocitrate dehydrogenase (IDH)1/2, additional sex comb-like 1 (ASXL1), enhancer of zeste homolog 2 (EZH2) and ubiquitously transcribed tetratric...

Net-spinning trichopteran larvae are used as examples of filter-feeding stream insects to show that various species feed upon a range of particle sizes. Evolution of individual species has resulted in cropping various particle sizes of drifting stream seston. Mechanisms of how this is achieved are discussed. The evolutionary diversity of filter feeders has important consequences for stream ecos...

Myeloid sarcoma (MS) is a subgroup of acute myeloid leukemia (AML) where myeloid blasts form a tumoral mass in extramedullary tissues [1]. MS may occur at any point during the disease course and almost every site of the body can be affected. Although MS is often diagnosed as an isolated event without concomitant bone marrow involvement, virtually all of these patients will develop overt hematol...

BACKGROUND AND AIM Overexpression of ecotropic viral integration site 1 (EVI1) is associated with aggressive disease in myeloid leukemia. We therefore studied its expression and function in cluster of differentiation 34-positive (CD34(+)) primary human hematopoietic progenitor cells. MATERIALS AND METHODS CD34(+) cells were differentiated into various myeloid lineages using the appropriate cy...
