BACKGROUND: Bone morphogenetic protein-2 (BMP-2) gene activated muscle tissue fragments can regenerate large bone defects in preclinical animal models. The use of tissue fragments instead of isolated cells expedites gene-enhanced tissue engineering and may raise chances for clinical translation. The present in vitro study investigates whether the osteoinductive effect of BMP-2 on muscle tissue fragments can be enhanced by use of the heterodimers BMP-2/6 or BMP-2/7. METHODS: Skeletal muscle tissue fragments from rats were cultured in vitro for up to 20 days in normal medium, osteogenic medium, or osteogenic medium supplemented with either a low (50 ng/ml) or high (200 ng/ml) concentration of recombinant human BMP-2, BMP-2/6 or BMP-2/7...

BACKGROUND: Previous studies have shown that foamy viral (FV) vectors are a promising alternative to gammaretroviral and lentiviral vectors and insulators can improve FV vector safety. However, in a previous analysis of insulator effects on FV vector safety, strong viral promoters were used to elicit genotoxic events. Here we developed and analyzed the efficacy and safety of a high-titer, clinically relevant FV vector driven by the housekeeping promoter elongation factor-1α and insulated with an enhancer blocking A1 insulator (FV-EGW-A1)...

INTRODUCTION: Intrathecal interleukin (IL)-10 delivered by plasmid or viral gene vectors has been proposed for clinical testing because it is effective for chronic pain in rodents, is a potential therapeutic for various human diseases, and was found to be nontoxic in dogs, when the human IL-10 ortholog was tested. However, recent studies in swine testing porcine IL-10 demonstrated fatal neurotoxicity. The present study aimed to deliver vector-encoded human IL-10 in swine, measure expression of the transgene in cerebrospinal fluid and monitor animals for signs of neurotoxicity...

BACKGROUND: Autoimmune hepatitis (AIH) is an inflammatory disease caused by an aberrant immune response to hepatic self-antigens in which regulatory T cells (Tregs) are critical for maintaining immunosupression. The soluble form of fibrinogen-like protein 2 (sFGL2), a novel effector molecule of Treg, is rarely investigated in AIH. In the present study, we dissected the role of sFGL2 in autoimmune hepatitis and its potential mechanism underlying AIH progression. METHODS: Plasma and intrahepatic sFGL2 levels, as well as Treg cells, were measured in both AIH patients and experimental autoimmune hepatitis (EAH) mice...

BACKGROUND: Levels of circulating vascular endothelial growth factor (VEGF) (a potent endothelial-cell-specific angiogenic factor) have been correlated with disease activity in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). In addition, several single nucleotide polymorphisms (SNPs), including the VEGFA -2578C/A, have been associated with RA in some populations. By contrast, the role of different VEGFA SNPs in the susceptibility to SLE has received little attention...

BACKGROUND: Gene correction at specific target loci provides a powerful strategy for overcoming genetic diseases. In the present study, we aimed to use an in vitro model for canine hemophilia B containing a single point mutation in the catalytic domain of the canine coagulation factor IX (cFIX) gene. To correct the defective gene via homology-directed repair (HDR), we designed transcription-activator like effector nucleases and clustered regularly interspaced short palindromic repeats including Cas9 (CRISPR/Cas9) for introduction of double-strand breaks at the mutation site...

BACKGROUND: A combination of tissue engineering methods employing mesenchymal stem cells (MSCs) together with gene transfer takes advantage of innovative strategies and highlights a new approach for targeting osteoarthritis (OA) and other cartilage defects. Furthermore, the development of systems allowing tunable transgene expression as regulated by natural disease-induced substances is highly desirable. METHODS: Bone marrow-derived equine MSCs were transduced with a lentiviral vector expressing interleukin-1 receptor antagonist (IL-1Ra) gene under the control of an inducible nuclear factor-kappa B-responsive promoter and IL-1Ra production upon pro-inflammatory cytokine stimulation [tumor necrosis factor (TNF)α, interleukin (IL)-1β] was analysed...

BACKGROUND: Gene therapy is one treatment that may ultimately cure type 1 diabetes. We have previously shown that the introduction of furin-cleavable human insulin (INS-FUR) to the livers in several animal models of diabetes resulted in the reversal of diabetes and partial pancreatic transdifferentiation of liver cells. The present study investigated whether streptozotocin-diabetes could be reversed in FRG mice in which chimeric mouse-human livers can readily be established and, in addition, whether pancreatic transdifferentiation occurred in the engrafted human hepatocytes...

BACKGROUND: The cellular and molecular mechanisms responsible for the age-associated delay of cutaneous wound healing are still not well understood. Previous studies have shown that miR-21 plays key roles during skin wound healing. We presumed that dysregulation of miR-21 may be involved in age-associated defects in wound healing and that miR-21 may be one potential therapeutic target by which to ameliorate wound defects in elderly subjects. METHODS: Circular full thickness excisional wounds were made on the dorsal skin of young (2-month-old) and aged (12-month-old) female mice...

BACKGROUND: We generated an adeno-associated virus (AAV) vector in which the human SLC2A1 gene, encoding glucose transporter type 1 (GLUT1), was expressed under the human endogenous GLUT1 promoter (AAV-GLUT1). We examined whether AAV-GLUT1 administration could lead to functional improvement in GLUT1-deficient mice. METHODS: We extrapolated human endogenous GLUT1 promoter sequences from rat minimal Glut1 promoter sequences. We generated a tyrosine-mutant AAV9/3 vector in which human SLC2A1-myc-DDK was expressed under the human GLUT1 promoter (AAV-GLUT1)...

Colorectal cancer is a leading form of cancer in both males and females. Early detection of individuals at risk of colorectal cancer allows proper treatment and management of the disease to be implemented, which can potentially reduce the burden of colorectal cancer incidence, morbidity and mortality. In recent years, the role of genetic susceptibility factors in mediating predisposition to colorectal cancer has become more and more apparent. Identification of high-frequency, low-penetrance genetic polymorphisms associated with the cancer has therefore emerged as an important approach which can potentially aid prediction of colorectal cancer risk...
