Interaction between the Wilms tumour factor-1 element in the promoter of Amh and a downstream enhancer is required for a strong expression of the gene in pre-pubertal sertoli cells
(Scientific Research Publishing, 2013-07)Amh (anti-Müllerian hormone) is a single copy gene which is expressed strongly in Sertoli cells in the foetal testis and participates in the onset of sexual differentiation. Its promoter driving the expression of a reporter ... -
Interaction of haptoglobin with hemoglobin octamers based on the mutation αAsn78Cys or βGly83Cys
(Scientific Research Publishing, 2012-01)Octameric hemoglobins have been developed by the introduction of surface cysteines in either the alpha or beta chain. Originally designed as a blood substitute, we report here the structure and ligand binding function; in ... -
Intergenic subset organization within a set of geographically-defined viral sequences from the 2009 H1N1 influenza A pandemic
(Scientific Research Publishing, 2012-01)We report a bioinformatic analysis of the datasets of sequences of all ten genes from the 2009 H1N1 influenza A pandemic in the state of Wisconsin. The gene with the greatest summed information entropy was found to be the ... -
Investigating genotoxicity of Eleusine indica by micronuclei assay in albino rats
(African Journal of Biological Sciences, 2019-01-16)Genotoxicity of Eleusine indica (Nkim enang: Efik) was investigated in the Wister strain albino rat (Rattus novergicus). Nine (9) male and nine (9) female rats were randomly assigned to three (3) groups, of which two were ... -
An investigation of 10 Y-STR loci and the detection of specific haplotype frequencies in Turkish population
(Scientific Research Publishing, 2011-07)This study is to survey 10 Y-STR loci in 241 males from Turkey. In this study, the 241 healthy and unrelated males living in different parts of Turkey for at least three generations were included. Genomic DNAs were isolated ... -
JnCML-like, an EF-hand motif-containing gene seasonally upregulated in the transition zone of black walnut (Juglans nigra L.)
(Scientific Research Publishing, 2011-10)The economic value of a black walnut (Juglans nigra L.) tree is strongly determined by the quality and quantity of darkly colored heartwood in its stem. To understand the regulation of heartwood formation, we analyzed the ... -
Knockdown of Dock7 in vivo specifically affects myelination by Schwann cells and increases myelin thickness in sciatic nerves without affecting axon thickness
(Scientific Research Publishing, 2012-07)During development of the peripheral nervous system (PNS), Schwann cells (SCs) wrap individual axons to form myelin sheaths, which act as surrounding insulators and markedly enhance the propagation of the action potential. ... -
