Generation of an integration-free human induced pluripotent stem cell line MUSIi010-A from occipital scalp fibroblasts of a male patient with androgenetic alopecia.

An induced pluripotent stem cell (iPSC) line, MUSIi010-A, was established by Sendai virus (SeV) transduction of scalp fibroblasts from a 59-year-old male with androgenetic alopecia (AGA). Pluripotency of the iPSC line was verified by immunofluorescence staining of pluripotent markers and by in vitro trilineage differentiation. The MUSIi010-A line was shown to retain normal karyotype and free of SeV vectors at passage 17.

Derivation of an induced pluripotent stem cell line (MUSIi004-A) from dermal fibroblasts of a 48-year-old spinocerebellar ataxia type 3 patient.

Dermal fibroblasts were obtained from a 48-year-old female patient with spinocerebellar ataxia type 3 (SCA3). Fibroblasts were reprogrammed by nucleofection with episomal plasmids, carrying L-MYC, LIN28, OCT4, SOX2, KLF4, EBNA-1 and shRNA against p53. The SCA3 patient-specific iPSC line, MUSIi004-A, was characterized by immunofluorescence staining to verify the expression of pluripotent markers.

Neuroprotection of -benzylcinnamide on scopolamine-induced cholinergic dysfunction in human SH-SY5Y neuroblastoma cells.

Alzheimer's disease, a progressive neurodegenerative disease, affects learning and memory resulting from cholinergic dysfunction. Scopolamine has been employed to induce Alzheimer's disease-like pathology and through alteration of cholinergic system. -benzylcinnamide (PT-3), purified from , has been shown to exhibit neuroprotective properties against amyloid-β-induced neuronal toxicity in rat cortical primary cell culture and to improve spatial learning and memory of aged rats through alleviating oxidative stress.

Potential role of N-benzylcinnamide in inducing neuronal differentiation from human amniotic fluid mesenchymal stem cells.

Neurodegenerative disorders are characterized by chronic and progressive loss of neurons in structure and function related to aging, such as Alzheimer's disease, the latter characterized by the degeneration of cholinergic neurons in basal forebrain connected to the cerebral cortex and hippocampus. Amniotic fluid mesenchymal stem cells (AF-MSCs) have been proposed as one of the candidates for stem cell therapy of nervous system disorders. This study demonstrates that incubation of AF-MSCs, obtained from 16 to 20 week pregnant women, with 10ng/ml bone morphogenetic protein (BMP)-9 for 48h in conditioned medium resulted in transdifferentiation to cholinergic neuronal-like cells.

Neuroprotective effects of diarylpropionitrile against β-amyloid peptide-induced neurotoxicity in rat cultured cortical neurons.

Alzheimer's disease is a major cause of dementia in the elderly that involves a β-amyloid peptide (Aβ)-induced cascade of an increase in oxidative damage and inflammation. The present study demonstrated the neuroprotective effects of diarylpropionitrile (DPN), a non-steroidal estrogen receptor β selective ligand, against 10 μM Aβ1-42-induced oxidative stress and inflammation in primary rat cortical cell culture. Pre-treatment with 1-100 nM DPN significantly decreased neuronal cell death by increasing cell viability through a significant attenuation in the reactive oxygen species level, downregulation of pro-apoptotic activated caspase-3 and Bax, and upregulation of anti-apoptotic Bcl-2, thereby mitigating apoptotic morphological alterations.

Protective effects of mangosteen extract on H2O2-induced cytotoxicity in SK-N-SH cells and scopolamine-induced memory impairment in mice.

Mangosteen extracts (ME) contain high levels of polyphenolic compounds and antioxidant activity. Protective effects of ME against β-amyloid peptide (Aβ), induced cytotoxicity have been reported. Here, we further studied the protective effects of ME against oxidative stress induced by hydrogen peroxide (H2O2) and polychlorinated biphenyls (PCBs), and demonstrated the protection against memory impairment in mice.

N-benzylcinnamide protects rat cultured cortical neurons from β-amyloid peptide-induced neurotoxicity.

The pathogenesis of Alzheimer's disease involves an amyloid β-peptide (Aβ)-induced cascade of elevated oxidative damage and inflammation. The present study investigates the protective effects and the underlying mechanisms of N-benzylcinnamide (PT-3), purified from Piper submultinerve. Against Aβ-induced oxidative stress and inflammation in rat primary cortical cell cultures.

The platelet amyloid precursor protein ratio as a diagnostic marker for Alzheimer's disease in Thai patients.

The platelet amyloid precursor protein (APP) ratio has recently been shown to be a promising diagnostic marker for Alzheimer's disease (AD). To evaluate its usefulness in Thai patients, platelet APP was analyzed by immunoblotting. The APP ratio was calculated as the ratio of the combined band density of the 120-kD and 130-kD isoforms compared to that of the 110-kD isoform.

Protective role of N-trans-feruloyltyramine against β-amyloid peptide-induced neurotoxicity in rat cultured cortical neurons.

Enhanced oxidative stress and inflammation play important roles in the pathogenesis of Alzheimer's disease (AD). Amyloid β-peptide (Aβ), a major component of amyloid plaques, is considered to have a causal role in the development and progress of AD by being the initiator of a pathological cascade leading to oxidative stress. The present study investigated the effect of N-trans-feruloyltyramine (NTF) purified from Polyalthia suberosa, an alkaloid shown to protect against oxidative stress and cell death.

Protective effect of mangosteen extract against beta-amyloid-induced cytotoxicity, oxidative stress and altered proteome in SK-N-SH cells.

Beta-amyloid (A beta) plays a key role in the pathogenesis of Alzheimer's disease (AD) by inducing neurotoxicity and cell death mainly through production of reactive oxygen species (ROS). Garcinia mangostana L. (mangosteen) has been recognized as a major source of natural antioxidants that could decrease ROS.
