[PMID: 32439509 DOI: 10.1016/j.fsi.2020.05.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 04/29/2020] [Accepted: 05/01/2020] [Indexed: 06/11/2023]
Abstract
Regucalcin (RGN), also known as senescence marker protein-30 (SMP30), plays a vital role in the regulation of Ca2+ homeostasis. In the present study, a regucalcin (designated as CgRGN) was identified from Pacific oyster Crassostrea gigas. The complete cDNA sequence of CgRGN was of 1059 bp, containing an open reading frame of 933 bp which encoded a protein of 310 amino acids. The deduced amino acid sequence of CgRGN shared similarity with other RGNs from the genome of C. gigas as well as other species. The mRNA transcripts of CgRGN were universally detected in all tested tissues, with higher level in hepatopancreas, labial palp, and gills. The relative expression level of CgRGN in hemocytes was significantly up-regulated (p < 0.05) at 3, 12, 72, and 96 h after the stimulation of lipopolysaccharide (LPS). After CgRGN expression was interfered by specific CgRGN-dsRNA, the hemocytes apoptosis rate increased dramatically at 12 h post LPS stimulation (1.56 fold, p < 0.01), compared to the control group. The caspase-3 activity in hemocytes and NO concentration in hemolymph increased significantly (p < 0.05) in dsCgRGN injection oysters. These results collectively indicated that CgRGN could suppress LPS-induced apoptosis and be involved in the immune response of oysters.

Abstract
The present research draws a map of the characteristic carbonylation of proteins in rats fed high-caloric diets with the aim of providing a new insight of the pathogenesis of metabolic diseases derived from the high consumption of fat and refined carbohydrates. Protein carbonylation was analyzed in plasma, liver and skeletal muscle of Sprague-Dawley rats fed a high-fat, high-sucrose (HFHS) diet by a proteomics approach based on carbonyl-specific fluorescence-labeling, gel electrophoresis and mass spectrometry. Oxidized proteins along with specific sites of oxidative damage were identified and discussed to illustrate the consequences of protein oxidation. The results indicated that long-term HFHS consumption increased protein oxidation in plasma and liver; meanwhile, protein carbonyls from skeletal muscle did not change. The increment of carbonylation by HFHS diet was singularly selective on specific target proteins: albumin from plasma and liver, and hepatic proteins such as mitochondrial carbamoyl-phosphate synthase (ammonia), mitochondrial aldehyde dehydrogenase, argininosuccinate synthetase, regucalcin, mitochondrial adenosine triphosphate synthase subunit beta, actin cytoplasmic 1 and mitochondrial glutamate dehydrogenase 1. The possible consequences that these specific protein carbonylations have on the excessive weight gain, insulin resistance and nonalcoholic fatty liver disease resulting from HFHS diet consumption are discussed.

Abstract
Regucalcin (RGN) is a calcium (Ca(2+))-binding protein widely expressed in vertebrate and invertebrate species, which is also known as senescence marker protein 30, due to its molecular weight (33 kDa) and a characteristically diminished expression with the aging process. RGN regulates intracellular Ca(2+) homeostasis and the activity of several proteins involved in intracellular signalling pathways, namely, kinases, phosphatases, phosphodiesterase, nitric oxide synthase and proteases, which highlights its importance in cell biology. In addition, RGN has cytoprotective effects reducing intracellular levels of oxidative stress, also playing a role in the control of cell survival and apoptosis. Multiple factors have been identified regulating the cell levels of RGN transcripts and protein, and an altered expression pattern of this interesting protein has been found in cases of reproductive disorders, neurodegenerative diseases and cancer. Moreover, RGN is a serum-secreted protein, and its levels have been correlated with the stage of disease, which strongly suggests the usefulness of this protein as a potential biomarker for monitoring disease onset and progression. The present review aims to discuss the available information concerning RGN expression and function in distinct cell types and tissues, integrating cellular and molecular mechanisms in the context of normal and pathological conditions. Insight into the cellular actions of RGN will be a key step towards deepening the knowledge of the biology of several human diseases.

Abstract
The role of regucalcin, which is a regulatory protein in intracellular signaling pathway, in the regulation of cell death was investigated by using the cloned rat hepatoma H4-II-E cells overexpressing regucalcin. The hepatoma cells (wild-type) and stable regucalcin (RC)/pCXN2 transfectants were cultured for 72 h in medium containing 10% fetal bovine serum (FBS) to obtain subconfluent monolayers. The proliferation of the cells was significantly suppressed in transfectants cultured for 72 h, as shown previously (Tsurusaki and Yamaguchi [2003]: J Cell Biochem 90:619-626). After culture for 72 h, cells were further cultured for 24-72 h in medium without FBS containing either vehicle, tumor necrosis factor-alpha (TNF-alpha; 0.1, 1, or 10 ng/ml) or thapsigargin (10(-7)-10(-5) M). The number of wild-type cells was significantly decreased by culture for 42 or 72 h in the presence of TNF-alpha (0.1, 1, or 10 ng/ml) or thapsigargin (10(-7)-10(-5) M). The effect of TNF-alpha (0.1 or 1 ng/ml) or thapsigargin (10(-7) or 10(-6) M) in decreasing the number of hepatoma cells was significantly prevented in transfectants overexpressing regucalcin. The presence of TNF-alpha (10 ng/ml) or thapsigargin (10(-5) M) caused a significant decrease in cell number of transfectants. Ca(2+)/calmodulin-dependent nitric oxide (NO) synthase activity in wild-type cells was significantly increased by culture with TNF-alpha (10 ng/ml) for 48 or 72 h. This increase was significantly prevented in transfectants. Culture with thapsigargin (10(-5) M) caused a significant increase in Ca(2+)/calmodulin-dependent NO synthase activity in wild-type cells or transfectants. TNF-alpha-induced decrease in the number of wild-type cells was significantly prevented by culture with N omega-nitro-L-arginine (10(-4) M), an inhibitor of caspase. Agarose gel electrophoresis showed the presence of low-molecular-weight deoxyribonucleic acid (DNA) fragments of adherent wild-type cells cultured with thapsigargin (10(-6) M), and this DNA fragmentation was not suppressed by culture with caspase inhibitor. Thapsigargin-induced DNA fragmentation was significantly suppressed in transfectants cultured with or without caspase inhibitor. This study demonstrates that overexpression of regucalcin has a suppressive effect on cell death induced by TNF-alpha or thapsigargin.

Abstract
The effect of regucalcin, a regulatory protein in the intracellular signaling process, on superoxide dismutase (SOD) activity in the cytosol of rat liver was investigated. The presence of zinc sulfate (10(-6) or 10(-5) m) or cupric sulfate (10(-6) m) in the enzyme reaction mixture caused a significant increase in SOD activity, indicating that Cu/Zn-SOD may be present in the liver cytosol. SOD activity was significantly increased by the addition of regucalcin (0.1, 0.25, or 0.5 microM) to the reaction mixture. The presence of dithiothreitol (DTT; 0.1, 0.5, or 1.0 mM), a protective reagent for the sulfhydryl group, caused a significant decrease in SOD activity. The effect of regucalcin (0.25 microM) in increasing SOD activity was not seen in the presence of DTT (1.0 mM). Meanwhile, SOD activity was significantly raised by the addition of N-ethylmaleimide (NEM; 0.5 or 1.0 mM), a modifying reagent for the sulfhydryl reagent. Regucalcin (0.25 microM) caused a significant increase in SOD activity in the presence of NEM (1.0 mM). The effect of regucalcin in increasing SOD activity may not involve the sulfhydryl group of SOD. This study demonstrates that regucalcin has an activatory effect on SOD in the liver cytosol of rats.

Abstract
The role of endogenous regucalcin, which is a regulatory protein in calcium signaling, in the regulation of nitric oxide (NO) synthase activity in the cloned rat hepatoma H4-II-E cells was investigated. Hepatoma cells were cultured for 24-72 h in the presence of fetal bovine serum (FBS; 10%). NO synthase activity in the 5,500 g supernatant of cell homogenate was significantly increased by the addition of calcium chloride (10 microM) and calmodulin (2.5 microg/ml) in the enzyme reaction mixture. The presence of trifluoperazine (TFP; 50 microM), an antagonist of calmodulin, inhibited the effect of calcium (10 microM) addition in increasing NO synthase activity, indicating the existence of Ca(2+)/calmodulin-dependent NO synthase in hepatoma cells. NO synthase activity was significantly decreased by the addition of regucalcin (10(-8) or 10(-7) M) in the reaction mixture without or with Ca(2+)/calmodulin addition. The effect of regucalcin (10(-7) M) in decreasing NO synthase activity was also seen in the presence of TFP (50 microM) or EGTA (1 mM). The presence of anti-regucalcin monoclonal antibody (10-50 ng/ml) in the reaction mixture caused a significant elevation of NO synthase activity. NO synthase activity was significantly suppressed in the hepatoma cells (transfectants) overexpressing regucalcin. This decrease was completely abolished in the presence of anti-regucalcin monoclonal antibody (50 ng/ml) in the reaction mixture. Moreover, the effect of Ca(2+)/calmodulin addition in increasing NO synthase activity in the hepatoma cells (wild-type) was completely prevented in transfectants. The present study demonstrates that endogenous regucalcin has a suppressive effect on NO synthase activity in the cloned rat hepatoma H4-II-E cells.
