In this experiment, RrF3’H gene was cloned from the petal of Rosa rugosa ‘Hunchun’ using RT-PCR, and bioinformatics analysis was performed. The RrF3’H gene’s full length of opening reading frame was 1687 bp, encoding 510 amino acids. The formulas of proteins encoded by RrF3’H were C2666H4149N699O734S24. The derived protein had a molecular weight of 58,506.95 Da. The aliphatic index was 90.94. It belongs to unstable hydrophilic protein. The protein consists of 46.76% α-helix, 31.04% random coil, 7.66% β-corner and 14.54% extended strand. The protein contains 21 Ser phosphorylation sites, 12 Thr phosphorylation sites, and 2 Tyr phosphorylation sites. The protein contained two O-glycosylation sites, located at positions 98 and 263 of the amino acid sequence respectively. The protein has a signal peptide site and a transmembrane structure. In addition, by comparing the expression levels of RrF3’H, we found RrF3’H was positively correlated with the depth of flower color.","PeriodicalId":65391,"journal":{"name":"美国分子生物学期刊(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70513518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the molecular biological mechanism of how the risk of cancer is increased in obesity or type 2 diabetes is not known. The aim this research is to investigate if the decreased expression of p27Kip1, a cell cycle repressor protein, plays a central role in this mechanism. Research Methods, Previous Studies and Theoretical Backgrounds: It is well known that the expression of p27Kip1 is increased by numerous nutritional or chemopreventive anti-cancer agents. But it has never been known that the expression of p27Kip1 could be decreased, rather than increased, and the risk of cancer could be increased, rather than decreased. This problem was solved recently and this new analytical method was used in this study. Results: 1) The expression of p27Kip1 was indeed significantly decreased in human obese type 2 diabetic individuals relative to the lean normal controls. 2) The expression of p27Kip1 was also significantly decreased in genetically obese rodents relative to the lean normal controls. Additionally, in obese rodents, the concentrations of glucose or insulin were significantly increased relative to the lean normal controls. 3) Using human cells cultured in vitro it was found that the increased concentrations of glucose or insulin decrease the expression of p27Kip1. Conclusions: These results suggest that higher concentrations of glucose or insulin increase the risk of various types of cancer in obesity or type 2 diabetes by decreasing the expression of p27Kip1.","PeriodicalId":65391,"journal":{"name":"美国分子生物学期刊(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70513435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed at evaluating the nephroprotective role of different doses of the tannin-rich extract of Chasmanthera dependens stem (TRECDS) on piroxicam-induced nephrotoxicity in adult male Wistar rats. Thirty-two adult rats were divided into four groups of eight rats per group and treated orally for ten days. Rats in group one received 0.5 ml normal saline (0.9% v/v) and served as normal control group. Rats in group two received 20 mg/kg body weight piroxicam alone. Rats in groups three and four received 20 mg/kg body weight of piroxicam with concomitant administration of 200 and 400 mg/kg body weight of TRECDS. At the expiration of the experiment, rats were sacrificed and the kidney was removed. Renal function was evaluated. The results showed that administration of piroxicam alone caused a significant elevation in the serum concentrations of albumin, creatinine, total protein, urea concentrations and the activity of renal nucleotidase with a reduction in the activity of glucose-6-phosphate dehydrogenase (G6PD) when compared to normal control (p < 0.05). Furthermore, renal tissue from the piroxicam alone treated group revealed a significant decrease in the activities of renal superoxide dismutase, catalase, glutathione peroxidase and glutathione-S-transferase as well as reduced glutathione with concomitant increase in lipid peroxidation and hydrogen peroxide generation. In addition, histological assessment of the renal tissue showed noticeable damage in piroxicam alone treated group. However, concomitant administration of TRECDS showed a dose-dependent reduction in the concentrations and the activity of the kidney markers with significant increase in the activities of G6PD and restores the antioxidant status of the kidney.

TnT’s function has been extensively described in vertebrates, but its role has been obscure in molluscan muscles. Our previous work indicated that the TnC and TnI subunits work in adductor phasic muscle, but not in catch muscle. Here, we have characterized TnT from the Japanese bivalve pearl oyster Pinctada fucata to start to explain the function of Tn in molluscan muscle contraction. We determined the primary structure of the full-length TnT protein from the P. fucata adductor muscle (Pifuc-TnT), and found that it is composed of 316 amino acid residues with a predicted molecular mass of 37.4 kDa. Multiple sequence alignment showed that Pifuc-TnT has an extension of >60 residues at the C-terminus that are not present in vertebrate TnTs, including known TnTs from other mollusks. Pifuc-TnT gene structure predictions using Splign alignment of the cDNA generated in this study and genome sequences indicated that Pifuc-TnT consists of 13 exons. Start and stop codons are located in exons 2 and 12, respectively. Quantitative real-time PCR revealed that the Pifuc-TnT gene was predominantly expressed in adductor phasic muscle, weakly in adductor catch muscle, slightly in gill, and not at all in mantle and foot. These findings suggest that TnT plays a regulatory role in adductor phasic muscle contraction, but not in catch contraction. Isothermal titration calorimetry revealed that unlike vertebrate TnTs, Pifuc-TnT does not interact with P. fucata tropomyosin-1 nor with tropomyosin-2. These findings in P. fucata imply that Tn functions differently in molluscan muscle than it does in vertebrates.","PeriodicalId":65391,"journal":{"name":"美国分子生物学期刊(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70513527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UNC-21-like kinase 2 (ULK2) also harbors putative SGK1 phosphorylation sites at both Ser507 (502RsRnsSG508) and Ser750 (745RtRttSV751) residues. Thus, the objective of this study was to determine whether Ser507 and Ser750 residues of ULK2 could be phosphorylation sites of SGK1 as one of its authentic substrate proteins. Using ULK2 507 and 750 serine residue un- or phosphorylation analog (S507AS750A or 507DS750D), we observed that modification of Ser507 or Ser750 residue was required to activate the kinase activity of ULK2 and sensitize ULK2 to stress or starvation while simultaneously enhancing its active state and autophagy characteristics, suggesting that phosphorylation at Ser750 or Ser507 residue could modulate its subcellular localization and protein interaction with AMPK1α to activate ULK2. We also observed that ULK2 autophagy activity was enhanced by GSK650394 (an SGK1 inhibitor) to compensate survival capacity through increasing its association with LC3 and phosphorylation. When SGK1 known to be associated with cell survival was inhibited by GSK650394, ULK2 autophagy pathway was activated to avoid cell death alternatively. Thus, our observations indicate that phosphorylation of ULK2 by SGK1 can regulate cell survival as an alternative modulation of ULK2 functions.","PeriodicalId":65391,"journal":{"name":"美国分子生物学期刊(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70513468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasma level of anti-CCP and rheumatoid factor antibodies confirmed diagnosis of RA patients that varied significantly between patients and healthy controls. Likewise, plasma levels of C-reactive protein, triglycerides, cholesterol, HDL-cholesterol and activities of AST and ALT exhibited significant variation between the two groups. In contrast, the levels of glucose, total protein, uric acid, LDL-cholesterol and plasma activity of ALP in RA patients had no significant deviations from healthy controls. Relationship between HLA genotype frequency and clinical parameters revealed that the mean levels of anti-CCP and rheumatoid factor antibodies were highest in the patients harboring HLA-DRB1*04 allele. These findings underpin the correlation between HLA genotype with clinical markers of RA which are indicative of disease severity.

Among saturated fatty acids palmitic acid (C16:0), stearic acid (C18:0) and myristic acid (C14:0) were the prominent fatty acids detected while among unsaturated fatty acid Oleic acid (C18:1c) and Linoleic acid (C18:2c) were the major fatty acids found. Under low temperature stress the percentage of saturated fatty acids was found to be lower (53%) in adapted cell line as compared to the un-adapted cell line (63%) while the percentage of saturation increased (83%) in adapted line under high temperature stress as compared to un-adapted line (70%). On the other hand at low temperature stress the percent level of unsaturated fatty acids in the adapted line was higher (48%) than the un-adapted cell line (37%).

Forty adult male rats were divided into five groups of eight rats and were treated orally once daily.

The experiment lasted for seven days. Liver injury was manifested biochemically by a significant increase in serum level or activities of hepatic markers (aminotransferases, alkaline phosphate, bilirubin, cholesterol and gamma glutamyl transferase). In addition, hepatic tissue from chloroquine-treated rats showed a significant increase in lipid peroxidation with a decrease in hepatic superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase and glutathione reservoirs. Moreover, the liver histopathologic evaluation revealed significant in chloroquine-treated rats.
