Article
An isolate of human immunodeficiency virus type 1 originally classified as subtype I represents a complex mosaic comprising three different group M subtypes (A, G, and I)
(1998)Full-length reference clones and sequences are currently available for eight human immunodeficiency virus type 1 (HIV-1) group M subtypes (A through H), but none have been reported for subtypes I and J, which have only ...

Article
Phenoxodiol, an anticancer isoflavene, induces immunomodulatory effects in vitro and in vivo
(2009)Phenoxodiol (PXD) is a synthetic analogue of the plant isoflavone genistein with improved anticancer efficacy. Various properties and mechanisms of action have been attributed to the drug, the most important being its ...

Regulation of retinoid X receptor-γ gene transcript levels in rat heart cells
(1998)Retinoid X receptor-γ (RXRγ) is a transcription factor that mediates retinoid signalling and is expressed in rat heart during adult life. However, its expression in embryonic and neonatal heart has not been investigated ...

Parental origin effects in human trisomy for chromosome 14q: Implications for genomic imprinting
(1998)Parental origin specific congenital anomalies have been noted in patients with uniparental disomy of the long arm of human chromosome 14 (UPD14). This suggests the presence of imprinted genes, consistent with observations ...

Article
Evidence of two distinct subsubtypes within the HIV-1 subtype A radiation
(2001)Members of HIV-1 group M are responsible for the vast majority of AIDS cases worldwide and have been classified on the basis of their phylogenetic relationships into nine roughly equidistant clades, termed subtypes. Although ...

Article
Targeting colon cancer cells with genistein-17.1A immunoconjugate.
(2003)We have shown that genistein, a major component of soy, has anti-colon cancer effects in vitro. These effects are attainable at high concentrations that are difficult to achieve in the serum. The purpose of this study was ...

Article
Differential expression of the rat retinoid X receptor γ gene during skeletal muscle differentiation suggests a role in myogenesis
(1997)Even though previous studies have shown that transcripts encoding the murine retinoid X receptor γ (RXRγ) are present in skeletal muscle of mouse embryos and that cultured myoblasts are induced to differentiate upon retinoid ...

Article
Identification of a mutation in complement factor H-related protein 5 in patients of Cypriot origin with glomerulonephritis
(2010)Summary Background Complement is a key component of the innate immune system, and variation in genes that regulate its activation is associated with renal and other disease. We aimed to establish the genetic basis for a ...

Resistance to etoposide in human leukemia HL-60 cells: Reduction in drug-induced DNA cleavage associated with hypophosphorylation of topoisomerase II phosphopeptides
(1996)Tumor cell resistance to anthracyclines and epipodophyllotoxins can be due to reduced drug accumulation and/or alterations in the activity of topoisomerase II (TOPO II). HL-60 cells selected in 0.05 μg/ml doxorubicin (DOX) ...

Article
Refinement of the gene locus for autosomal dominant medullary cystic kidney disease type 1 (MCKD1) and construction of a physical and partial transcriptional map of the region
(2001)Autosomal dominant medullary cystic kidney disease (MCKD) is an adult onset tubulointerstitial nephropathy that leads to salt wasting and end-stage renal failure. A gene locus (MCKD1) has been mapped on chromosome 1q21. ...

Altered Phosphorylation, Biosynthesis and Degradation of the 170 kDa Isoform of Topoisomerase II in Amsacrine-Resistant Human Leukemia Cells
(1993)Resistance to amsacrine in HL-60/AMSA is 50-100 fold compared to the parental HL-60/S cells. Synthesis and phosphorylation of topoisomerase II (TOPO II) were 2-3 fold lower in HL-60/AMSA compared to HL-60/S cells metabolically ...

Limited cross-border infections in patients newly diagnosed with HIV in Europe
(2013)Background: International travel plays a role in the spread of HIV-1 across Europe. It is, however, not known whether international travel is more important for spread of the epidemic as compared to endogenous infections ...

Article
Patterns of transmitted HIV drug resistance in Europe vary by risk group
(2014)Background: In Europe, a continuous programme (SPREAD) has been in place for ten years to study transmission of drug resistant HIV. We analysed time trends of transmitted drug resistance mutations (TDRM) in relation to the ...

Article
Balanced translocations for the analysis of imprinted regions of the mouse genome.
(2001)Experimental studies that investigate the functional and mechanistic properties of an imprinted locus require material in which the two parental chromosome homologs can be easily distinguished. The use of animals with ...

Article
Increase in transmitted resistance to non-nucleoside reverse transcriptase inhibitors among newly diagnosed HIV-1 infections in Europe
(2014)Background: One out of ten newly diagnosed patients in Europe was infected with a virus carrying a drug resistant mutation. We analysed the patterns over time for transmitted drug resistance mutations (TDRM) using data ...

Increased number of MicroRNA target sites in genes encoded in CNV regions. Evidence for an evolutionary genomic interaction
(2011)MicroRNAs (miRNAs) and copy number variations (CNVs) are two newly discovered genetic elements that have revolutionized the field of molecular biology and genetics. By performing in silico whole genome analysis, we demonstrate ...

Molecular investigation and long-term clinical progress in Greek Cypriot families with recessive distal renal tubular acidosis and sensorineural deafness due to mutations in the ATP6V1B1 gene
(2006)The spectrum of distal renal tubular acidosis (dRTA) includes a genetically heterogeneous group of inherited conditions of both autosomal-dominant and recessive mode of inheritance. The basic defect islinked to the renal ...
