Sequence analysis of the small subunit ribosomal DNA (SSU-rDNA) and elongation factor 1 alpha (ef1α) was performed on Giardia cysts isolated from faeces collected from a quenda (Isoodon obesulus) in the southwest of Western Australia. The SSU-rDNA and ef1α were sequenced in their entirety and correspondingly aligned with the published sequence information of other known species and genotypes of...
Induced pluripotent stem cell (iPSC) therapies offer a promising path for patient-specific regenerative medicine. However, tumor formation from residual undifferentiated iPSC or transformation of iPSC or their derivatives is a risk. Inclusion of a suicide gene is one approach to risk mitigation. We introduced a dimerizable-"inducible caspase-9" (iCasp9) suicide gene into mouse iPSC (miPSC) and ...
The promoter is a major element in the expression cassette of gene therapy vectors. Optimal promoter selection can enhance target specificity and gene expression. Recently, we evaluated three different human elongation factor 1 alpha (EF1α) promoters. The three promoters were put into the same expression vector, pAC-luc, driving expression of the luciferase cDNA. The activity from one EF1α prom...
The expression of predominant housekeeping genes used in RT-qPCR can vary during development and differentiation. The frequently used housekeeping genes (ACTB, GAPDH, 18S rRNA, EF1α and RPL 13a) were evaluated during an early stage of the osteogenic differentiation of mouse bone marrow-derived mesenchymal stem cells (mMSCs) (under normal conditions or treated with CCG-4986) to identify housekee...
Hematopoietic Stem Cell (HSC) targeted gene transfer is an attractive treatment option for a number of hematopoietic disorders caused by single gene defects. However, extensive methylation of promoter sequences results in silencing of therapeutic gene expression. The choice of an appropriate promoter is therefore crucial for reproducible, stable and long-term transgene expression in clinical ge...
Paclitaxel (Taxol), a potent drug of natural origin isolated from the bark of the Pacific yew, is widely used for treating ovarian, lung and breast cancers. Currently, there is little information regarding the specific mechanism underlying the anticancer activity of paclitaxel. In the present study, we found that 5-amino-1-β-D-ribofuranosyl-imidazole-4-carboxamide (AICAR), a well-known activato...
The aim of the present study was to explore the feasibility of lentiviral-mediated sodium iodide symporter (NIS) gene delivery for monitoring bone marrow-derived mesenchymal stem cell (BMSC) transplantation into the infarcted myocardium. For this purpose, we constructed a lentiviral vector (Lv-EF1α-NIS-IRES-EGFP) expressing NIS and enhanced green fluorescent protein (EGFP), and introduced it in...
BACKGROUND Orientia tsutsugamushi, the causative agent of scrub typhus, is an obligate intracellular bacterium. Previously, a large number of genes that encode proteins containing eukaryotic protein-protein interaction motifs such as ankyrin-repeat (Ank) domains were identified in the O. tsutsugamushi genome. However, little is known about the Ank protein function in O. tsutsugamushi. METHODO...
The Pleurotus eryngii species complex comprises at least six varieties (var. eryngii (DC.: Fr) Quel., ferulae Lanzi, elaeoselini Venturella et al., nebrodensis (Inzenga) Sacc., tingitanus Lewinsohn et al. and tuoliensis C.J. Mou). This species is unique among the genus Pleurotus because in nature it is found in association with certain species of the Apiaceae (Umbelliferae) and Asteraceae (Comp...
BACKGROUND Constitutive promoters that ensure sustained and high level gene expression are basic research tools that have a wide range of applications, including studies of human embryology and drug discovery in human embryonic stem cells (hESCs). Numerous cellular/viral promoters that ensure sustained gene expression in various cell types have been identified but systematic comparison of their...
