AMP-activated protein kinase; apoptosis; calcium; cardiomyocytes; cardiomyopathy; diabetic complications; endoplasmic reticulum; epidemiological studies; gene expression; ischemia; protective effect; reactive oxygen species; signal transduction; stress response
Abstract:
... Previous epidemiological studies have shown that methylglyoxal (MGO) levels are highly regulated in diabetic cardiovascular diseases. We have also previously reported that MGO mediates ER stress and apoptosis in cardiomyocytes. Furthermore, activated protein C (APC) has recently been shown to play a protective role against ER stress, as well as a cardioprotective role against ischemia and reperfus ...

Abstract:
... Recent studies suggest that forced activation of AMP-activated protein kinase (AMPK) could inhibit melanoma cell proliferation. In this report, we evaluated the anti-melanoma cell activity by a novel small-molecular AMPK activator, GSK621. Treatment of GSK621 decreased survival and proliferation of human melanoma cells (A375, WM-115 and SK-Mel-2 lines), which was accompanied by activation of caspa ...

Abstract:
... Epicardial progenitor cells (EpiCs) have a crucial role in cardiac development and vasculature formation. Here we detected the expression of Angiotensin II (Ang II) receptors AT1 and AT2 on EpiCs and demonstrated that AngII could increase the expression of smooth muscle specific markers, including α-smooth muscle actin (α-SMA) and myosin heavy chain 11 (Myh11) in EpiCs. Moreover, the expression of ...

Abstract:
... Dopamine is a neurotransmitter that has many functions in the nervous and immune systems. Ferroptosis is a non-apoptotic form of regulated cell death that is involved in cancer and neurodegenerative diseases. However, the role of dopamine in ferroptosis remains unidentified. Here, we show that the non-oxidative form of dopamine is a strong inhibitor of ferroptotic cell death. Dopamine dose-depende ...

Abstract:
... Hedgehog (Hh) signaling plays key roles in animal development and tissue homeostasis. Binding of the secreted ligand to its Ptch1 receptor triggers Hh signaling through distinct canonical or noncanonical signaling pathways. Canonical Hh signaling leads to the activation of Gli transcription factors to induce Hh target-gene expression. In contrast, noncanonical Hh signaling regulates cytoskeleton r ...

Increased iron in prion-related disease has been observed due to the prion protein-ferritin complex. Additionally, the accumulation and conversion of recombinant PrP (rPrP) is specifically derived f ...

Abstract:
... The Na+/Ca2+ exchanger 1 (NCX1) is an essential Ca2+ efflux system in cardiomyocytes. Although NCX1 is distributed throughout the sarcolemma, a subpopulation of NCX1 is localized to transverse (T)-tubules. There is growing evidence that T-tubule disorganization is a causal event that shifts the transition from hypertrophy to heart failure (HF). However, the detailed molecular mechanisms have not b ...

In the present study, we found that HMGB1 induced migration of in human non-small cell lung cancer (NSCLC) cells by up-regulating integrin αvβ3 expression. Further investigation evidenced that HMGB1 activated Toll-like receptor ...
