Previous studies have revealed that HBx expression has anti-apoptotic effects, resulting in increased drug resistance in HCC cells. Thus, we examined if sorafenib efficiently induces apoptosis in HBx-overexpressing HCC cells. Noticeably, sorafenib efficiently induced apoptosis, even in HBx-expressing HepG2 cells

Hereditary xanthinuria (HX) is a rare inherited disorder caused by a deficiency of xanthine dehydrogenase/oxidase (XDH/XO). Missing XDH/XO activity leads to undetectable levels of uric acid excessively replaced by xanthine in serum/urine. The allopurinol loading test has been traditionally used

Transplantation of insulin (INS)-secreting cells differentiated in vitro from stem cells promises a safer and easier treatment of severe diabetes mellitus. A volatile bioactive compound, hydrogen sulfide (H2S), promotes cell differentiation; human tooth-pulp stem cells undergo hepatic differentiation. The aim

The conversion of differentiated cells into insulin-producing cells is a promising approach for the autologous replacement of pancreatic cells in patients with type 1 diabetes (T1D). At present, cellular reprogramming strategies encompass ethical problems, epigenetic failure or teratoma formation, which
