Article Synopsis
  • The study analyzed how specific mutations at Asp187 and Ser188 in the protease cocoonase (CCN) affect its ability to recognize substrates and carry out enzymatic activity.
  • Mutations at Asp187 significantly reduced enzymatic activity, highlighting its key role, while changes at Ser188 had a lesser impact but still contributed to substrate recognition.
  • Substituting Asp187 with other residues resulted in new substrate specificities, suggesting that the structure of the precursors remains stable, which may affect how the enzyme interacts with substrates and its overall catalytic function.

Article Synopsis
  • - Chronic kidney disease-mineral and bone disorder (CKD-MBD) is a systemic issue that negatively impacts the health and prognosis of CKD patients, making effective management crucial.
  • - This study analyzed data from 30,977 CKD patients in the Japan Chronic Kidney Disease Database Extension to explore the link between proteinuria and CKD-MBD.
  • - Results indicated that higher levels of proteinuria (up to 3+) are significantly associated with increased risks of hyperphosphatemia, hypocalcemia, and hypomagnesemia, regardless of kidney function measured by eGFR.

Article Synopsis
  • A study explored the potential of serum autotaxin (ATX) as a predictor for liver-related events (LRE) in patients with primary biliary cholangitis (PBC).
  • During a median follow-up of 9.7 years of 190 untreated patients, those with ATX levels ≥1.086 mg/L experienced significantly more LRE compared to those with lower levels (33.3% vs 3.6%).
  • The research suggests that ATX is a strong independent predictor for LRE, outperforming existing markers, and aligns with findings from a separate validation cohort of PBC patients.

The aim of this study was to clarify the transcriptional and metabolic characteristics of C2C12 myoblasts cultured in Dulbecco's Modified Eagle Medium (DMEM) containing 20 % chicken serum (CHS) (C2C12-CHS cells) compared with C2C12 myoblasts cultured in DMEM containing 20 % fetal bovine serum (FBS) (C2C12-FBS cells). After 3 days of culture, C2C12-CHS cells showed a marked accumulation of lipid droplets, accompanied by increased expression levels of brown adipocyte-related genes (i.e.

Background: Lower extremity peripheral arterial disease is a potentially lethal cardiovascular complication in patients undergoing hemodialysis. Anemia is a risk factor for cardiovascular disease among the hemodialysis population. However, whether blood hemoglobin concentration is associated with the risk of peripheral arterial disease progression in this population remains undetermined.

Background: Circulating autotaxin (ATX) levels have been reported to correlate with liver inflammation activity and liver fibrosis severity in patients with non-alcoholic fatty liver disease (NAFLD). The objective of this study is to investigate whether serum ATX could predict liver-related events (LRE) in NAFLD patients.

Methods: This retrospective investigation includes 309 biopsy-proven NAFLD patients registered at Shinshu University Hospital.

Imidazole dipeptides possess important bioregulatory properties in animals. This study aimed to evaluate the effect of high ambient temperature on muscle imidazole dipeptides (carnosine, anserine, and balenine) in broiler chickens. Sixteen 14-day-old male broiler chickens were divided into two groups, which were reared under thermoneutral (25 ± 1 °C) or cyclic high ambient temperature (35 ± 1 °C for 8 h/day) for 4 weeks.

Purpose: This study aims to compare the effect of using O-arm and C-arm fluoroscopy on the surgical outcomes of occipitocervical fixation.

Methods: The study included patients who underwent occipitocervical fixation using O-arm or C-arm between 2005 and 2021. Of 56 patients, 34 underwent O-arm-assisted surgery (O-group) and 22 underwent C-arm-assisted surgery (C-group).

Exogenous nutrients are essential for body and skeletal muscle growth in newly hatched chicks, and delaying post-hatch feeding negatively affects body growth, meat yield, and meat quality. The aim of this study was to investigate the effects of delayed post-hatch feeding on the metabolic profiles of broiler chickens using a combination of targeted and untargeted metabolomics. Newly hatched chicks had either immediate free access to feed (freely fed chicks) or no access to feed from 0 to 2 days of age (delayed-fed chicks); both groups were subsequently provided feed until 13 days of age.

Article Synopsis
  • Proopiomelanocortin (POMC) is an important precursor protein that produces various peptide hormones, but the biological activity of its joining peptide (JP) region has not been studied until now.
  • Through sequence analyses of mammalian POMC, researchers identified an RGD motif in several species, indicating that the JP may have cell adhesion properties.
  • Experiments showed that synthetic JP peptides enhanced cell adhesion in 293T cells and that a specific human JP variant exhibited even stronger adhesion activity, highlighting its potential role in cell adhesion and signaling related to POMC-derived hormones.

Functional dipeptides carnosine and anserine are abundant in muscle. We determined the effect of short-term dietary histidine (His) content on muscle carnosine and anserine contents and meat quality of broilers. Three groups of 28-day-old female broilers were fed diets with His contents of 67%, 100%, or 150% of requirement for 10 days before market (His contents 0.

The concentration of -methylhistidine in plasma provides an index of skeletal muscle protein breakdown. This study aimed to establish a quantitative method for measuring the concentrations of -methylhistidine and its isomer -methylhistidine in chicken plasma, using liquid chromatography-tandem mass spectrometry with stable isotope dilution analysis. The acceptable linear ranges of detection were 1.

Gamma-aminobutyric acid (GABA) is considered as a potential candidate substance that mediates the effects of intestinal bacteria on human mental health. In the present study, we evaluated the effect of water-soluble cellulose acetate (WSCA), a type of cellulose ester, on fermentation and microbial profiles, and GABA production in human stool cultures prepared from fresh feces from volunteers. In addition, the GABA-producing ability of Bacteroides uniformis, which can utilize WSCA, was evaluated in a pure-culture study.

Investigations of protein folding have largely involved the use of disulfide-containing proteins, since the disulfide-coupled folding of proteins allows folding intermediates to be trapped and their conformations determined. However, studies of the folding mechanisms of mid-size proteins face several problems, one of which is that detecting folding intermediates is difficult. Therefore, to solve this issue, a novel peptide reagent, maleimidohexanoyl-Arg-Tyr-NH, was designed and applied to the detection of folding intermediates of model proteins.

Heat-stable enterotoxin (ST) produced by Enterotoxigenic is responsible for causing acute diarrhea in infants in developing countries. However, the chemical synthesis of ST peptides with the native conformation and the correct intra-molecular disulfide bonds is a major hurdle for vaccine development. To address this issue, we herein report on the design and preparation of ST analogs and a convenient chemical method for obtaining ST molecules with the correct conformation.

Cocoonase is folded in the form of a zymogen precursor protein (prococoonase) with the assistance of the propeptide region. To investigate the role of the propeptide sequence on the disulfide-coupled folding of cocoonase and prococoonase, the amino acid residues at the degradation sites during the refolding and auto-processing reactions were determined by mass spectrometric analyses and were mutated to suppress the numerous degradation reactions that occur during the reactions. In addition, the Lys residue at the propeptide region was also mutated to estimate whether the entire sequence is absolutely required for the activation of cocoonase.
