Effects of Capsaicin on Adipogenic Differentiation in Bovine Bone Marrow Mesenchymal Stem Cell

Capsaicin is a major constituent of hot chili peppers that influences lipid metabolism in animals. In this study, we explored the effects of capsaicin on adipogenic differentiation of bovine bone marrow mesenchymal stem cells (BMSCs) in a dose- and time-dependent manner. The BMSCs were treated with various concentrations of capsaicin (0, 0.1, 1, 5, and 10 μM) for 2, 4, and 6 days. Capsaicin suppressed fat deposition significantly during adipogenic differentiation. Peroxisome proliferator-activated receptor gamma, cytosine-cytosine-adenosine-adenosine-thymidine/enhancer binding protein alpha, fatty acid binding protein 4, and stearoyl-CoA desaturase expression decreased after capsaicin treatment. We showed that the number of apoptotic cells increased in dose- and time-dependent manners. Furthermore, we found that capsaicin increased the expression levels of apoptotic genes, such as B-cell lymphoma 2-associated X protein and caspase 3. Overall, capsaicin inhibits fat deposition by triggering apoptosis

Generation of induced pluripotent stem cell (iPSC) line from Charcot-Marie-Tooth disease patient with MPZ mutation (CMT1B)

Charcot-Marie-Tooth disease (CMT1B) is an inherited neurological disorder caused by mutation of the myelin protein zero (MPZ) gene. We generated an induced pluripotent stem cell (iPSC) line from an 81-year-old patient with CMT1B by electroporating of lymphoblastoid cell lines with episomal plasmids encoding OCT4, SOX2, KLF4, L-MYC, LIN28, and p53-targeting shRNA. The established iPSCs expressed various pluripotency markers, demonstrated the potential to differentiate into cells of the three germ layers in vitro, had a normal karyotype and retained the MPZ mutation

Generation of induced pluripotent stem cell (iPSC) line from a 21-year-old X-linked adrenoleukodystrophy (X-ALD) patient

X-linked Adrenoleukodystrophy (X-ALD) is a genetic disease that caused by mutations in adenosine triphosphate [ATP]-binding-cassette transporter superfamily D member 1 (ABCD1) gene. We generated an induced pluripotent stem cell (iPSC) line from a 21-year-old male X-ALD patient-derived fibroblasts by Sendai virus mediated reprogramming. Established iPSCs stably expanded while maintaining immunoreactivity for various pluripotency markers and alkaline phosphatase, as well as normal 44 + XY karyotype. Under the differentiation condition, the cells gave rise to cells of three germ layers

Generation of two induced pluripotent stem cell (iPSC) lines from X-linked adrenoleukodystrophy (X-ALD) patients with adrenomyeloneuropathy (AMN)

X-linked adrenoleukodystrophy (X-ALD) is an inherited disorder caused by a mutation in the ATP-binding cassette transporter subfamily D member 1 (ABCD1) gene. We generated two induced pluripotent stem cell (iPSC) lines from X-ALD patients with adrenomyeloneuropathy (AMN) by Sendai virus containing OCT4, SOX2, KLF4 and c-MYC. Established iPSC lines expressed various pluripotency markers, had differentiation potential of three germ layers in vitro, had normal karyotype and retained ABCD1 mutation
