Myocardial infarction due to coronary artery occlusion leads to adverse cardiac remodeling and heart failure. Apoptotic loss of cardiomyocytes near the ischemia area enlarges infarct area and promotes cardiac remodeling. Protein arginine methyltransferase 4 (PRMT4), a type I protein arginine methyltransferase, is involved in many cellular processes...

Melanocortin 4 receptor (MC4R)-deficient mice had been used for several years to study human nonalcoholic steatohepatitis (NASH). However, although liver pathologic and biochemical indicators have been examined, mice models do not always faithfully display the phenotype of the human disease. In this study, we investigated the MC4R knockout phenotyp...

Two mGluR7-derived peptides corresponding to residues 856 to 879 and 856 to 875 are known to bind to Ca2+-saturated calmodulin (Ca2+/CaM), and their binding manners are thought to differ. Met872 function is believed as one of the anchor residues for CaM-binding only in the shorter peptide. To uncover the role of Met872 in CaM-binding, we prepared a...

In the work, we performed densitometry of thick filaments of the Gray's mussel catch muscle; densitometry included determination of electrophoretic dye binding constants of proteins. The results of densitometry showed that the content of twitchin in thick filaments is significantly (10 times) lower than the content of myosin. We performed an in vit...

Loss of total muscle force during aging has both atrophic and non-atrophic components. The former deficit is a direct consequence of reduced muscle mass while the latter has been attributed to a depression of excitation-contraction (EC) coupling. It is well established that age-onset reductions in sex hormone production regulate the atrophic compon...

Astrocytes regulate various brain functions, for which Ca2+ release from the endoplasmic reticulum (ER) often play crucial roles. Because astrocytic ER Ca2+ release is robust and frequent, the ER Ca2+ refilling mechanism should be critical for ongoing Ca2+ signaling in astrocytes. In this study, we focused on the putative functional significance of...

Molecular hydrogen (H2) is recognized as a medical gas applicable to numerous diseases including neurodegenerative diseases, metabolic disorders, and rheumatoid arthritis. Although the efficacy of H2 is reportedly attributed to its scavenging capability against the hydroxyl radical, the mechanisms underlying its therapeutic efficacy are not fully u...

Xenopus tropicalis tadpoles can regenerate an amputated tail, including spinal cord, muscle and notochord, through cell proliferation and differentiation. However, the molecular mechanisms that regulate cell proliferation during tail regeneration are largely unknown. Here we show that JunB plays an important role in tail regeneration by regulating ...

Cis-prenyltransferases are enzymes responsible for the biosynthesis of glycosyl carrier lipids, natural rubber, and some secondary metabolites. Certain organisms, including some archaeal species, possess multiple genes encoding cis-prenyltransferase homologs, and the physiological roles of these seemingly-redundant genes are often obscure. Cis-pren...

Aberrant expression of long non-coding RNAs (lncRNAs) has been observed in hepatocellular carcinoma (HCC) and confirmed to participate in the initiation and progression of HCC. In the present study, we identified a novel functional lncRNA, hedgehog-interacting protein antisense RNA 1 (HHIP-AS1). The expression levels of HHIP-AS1 were significantly ...
