Stem cell therapy for damaged cardiac tissue is currently limited by a number of factors, including inability to obtain sufficient cell numbers, the potential tumorigenicity of certain types of stem cells and the possible link between stem cell therapy and the development of malignant arrhythmias. In this study, we investigated whether human amniotic(More)
The ability to extract somatic cells from a patient and reprogram them to pluripotency opens up new possibilities for personalized medicine. Induced pluripotent stem cells (iPSCs) have been employed to generate beating cardiomyocytes from a patient's skin or blood cells. Here, iPSC methods were used to generate cardiomyocytes starting from the urine of a(More)
The aim of this study was to determine whether adipose derived stem cells (ADSCs) expressing vascular endothelial growth factor (VEGF) gene can improve endothelial function, recover the impaired VEGF signaling pathway and enhance smooth muscle contents in a rat diabetic erectile dysfunction (DED) model. DED rats were induced via intraperitoneal injection of(More)
Loss-of-function mutations in the myotubularin gene (MTM1) cause X-linked myotubular myopathy (XLMTM), a fatal, congenital pediatric disease that affects the entire skeletal musculature. Systemic administration of a single dose of a recombinant serotype 8 adeno-associated virus (AAV8) vector expressing murine myotubularin to Mtm1-deficient knockout mice at(More)
BACKGROUND Dystrophin-deficient cardiomyopathy is a growing clinical problem without targeted treatments. We investigated whether nicorandil promotes cardioprotection in human dystrophin-deficient induced pluripotent stem cell (iPSC)-derived cardiomyocytes and the muscular dystrophy mdx mouse heart. METHODS AND RESULTS Dystrophin-deficient iPSC-derived(More)
Ischemic heart disease remains one of the most common causes of mortality in developed countries. Recently, stem cell therapy is being considered for treating ischemic heart diseases. On the other hand, there has been evidence of chondro-osteogenic mass formation after stem cell injection in the heart. In a recent publication, Chiavegato et al. (J Mol Cell(More)
PURPOSE To review mechanisms underlying mutant p53 (mutp53) gain of function (GOF) and mutp53-induced chemoresistance, and to investigate the role of mutp53 in response to clinical chemotherapy. METHODS We searched the PubMed database for clinical studies from the past decade, including data evaluating the impact of mutp53 in clinical chemotherapy(More)
INTRODUCTION We established a colony of dogs that harbor an X-linked MTM1 missense mutation.Muscle from affected male dogs exhibits reduction and altered localization of the MTM1 gene product, myotubularin, and provides a model analogous to X-linked myotubular myopathy (XLMTM). METHODS We studied hindlimb muscle function in age-matched canine XLMTM(More)
BACKGROUND Growing studies have revealed the association between polymorphisms in the Toll-like receptor 9 (TLR9) and susceptibility to cancer, however, the results remained inconsistent. METHODOLOGY/PRINCIPAL FINDINGS To assess the effect of three selected SNPs (rs352140, rs5743836 and rs187084) in TLR9 on cancer, we performed a meta-analysis based on 11(More)
Human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CMs) offer unprecedented opportunities to study inherited heart conditions in vitro, but are phenotypically immature, limiting their ability to effectively model adult-onset diseases. Cardiomyopathy is becoming the leading cause of death in patients with Duchenne muscular dystrophy (DMD), but(More)
