... Contamination of V. parahaemolyticus in raw product and culture areas of Crassostrea gigas has been a concern in food hygiene and infectious diseases in the shellfish aquaculture industry for decades. Although numerous researchers have presently objective of decreasing pathogen microorganism contaminated load in raw oysters or genetics improvement for prevention, the in-depth information at the mo ...
recombinantproteins, etc ; biotechnology; glycoproteins; glycosylation; markets; therapeutics; Show all 6 Subjects
Abstract:
... Proteins continue to represent a large fraction of the therapeutics market, reaching over a hundred billion dollars in market size globally. One key feature of protein modification that can affect both structure and function is the addition of glycosylation following protein folding, leading to regulatory requirements for the accurate assessment of protein attributes, including glycan structures. ...

Abstract:
... Biologics represent the fastest growing group of therapeutics, but many advanced recombinant protein moieties remain difficult to produce. Here, we identify metabolic engineering targets limiting expression of recombinant human proteins through a systems biology analysis of the transcriptomes of CHO and HEK293 during recombinant expression. In an expression comparison of 24 difficult to express pr ...

Abstract:
... Fragment antigen-binding (Fab) has several advantages in the treatment and diagnosis of some diseases. The lack of highly efficient affinity chromatography platform creates a purification bottleneck for the downstream processing of Fab-based products, which raises the urgent need for a novel immunoglobin G (IgG)-binding domain (IgBD) with both high affinity and broad specificity for Fab. SpGC₃FₐbR ...

Abstract:
... Expression of proteins in bacterial host cells, particularly E.coli, has gained much attention in recent years. Low expression outcome is the main technical drawback associated with this procedure, further restricting its largescale application in industry. Therefore, application of new amendments or reformations are required before further proceedings. Extremely low frequency magnetic fields (ELF ...

Abstract:
... Optimization of the fermentation process for recombinant protein production (RPP) is often resource-intensive. Machine learning (ML) approaches are helpful in minimizing the experimentations and find vast applications in RPP. However, these ML-based tools primarily focus on features with respect to amino-acid-sequence, ruling out the influence of fermentation process conditions. The present study ...

Abstract:
... Cry toxins from Bacillus thuringiensis (Bt) have been extensively applied in agriculture to substitute the use of chemical insecticides. We have previously reported the use of a coexpression system in which late embryogenesis abundant (LEA) peptides under the control of the lac promoter increase the expression of insecticidal proteins in Bt. The use of lactose to induce the expression of LEA pepti ...

Abstract:
... Chinese hamster ovary (CHO) cells have been the predominant host for recombinant protein production over the past decades with major efforts directed towards cell line engineering to increase amount and quality of biopharmaceutics. Emerging omics approaches and corresponding techniques now allow an extensive characterization of cellular expression systems. Technical improvements in sequencing, mas ...

Abstract:
... Miracle fruit, Synsepalum dulcificum, produces a unique taste-modifying protein, miraculin (MIR), which has an attractive potential for commercial application as a novel low-calorie sweetener. To establish a stable supply system for MIR, a previous study established a platform for recombinant MIR (rMIR) production in tomato plants and demonstrated that native miraculin from miracle fruit (nMIR) an ...

Abstract:
... BACKGROUND: Escherichia coli is a widely used tool for the over-expression of human proteins for studying structure and function. The toxicity of human proteins for E. coli often hampers the expression. This study aims to find conditions for the expression of a membrane transporter known as the carnitine transporter CT2. The knowledge on this transporter is scarce, thus obtaining the recombinant p ...

Abstract:
... The use of serological tests containing multiple immunodominant antigens rather than single antigens have the potential to improve the diagnostic performance in Cystic Echinococcoses (CE) as a complement tool to clear the inconclusive imaging data. Here, we comparatively evaluated the diagnostic value of Hydatid Fluid (HF) and the recently described recombinant multi-epitope antigen DIPOL in IgG-E ...

Abstract:
... Recombinant protein biopharmaceuticals comprise a significant portion of the current drug development landscape. The glycosylation profile of these proteins is a key quality parameter as it can affect their safety, efficacy, and stability. However, glycan analysis is challenging because of the complexity of their structures. To overcome this challenge in achieving accurate glycan identification, c ...

Abstract:
... Yeasts and especially Pichia pastoris (syn Komagataella spp.) are popular microbial expression systems for the production of recombinant proteins. One of the key advantages of yeast host systems is their ability to secrete the recombinant protein into the culture media. However, secretion of some recombinant proteins is less efficient. These proteins include antibody fragments such as Fabs or scFv ...

Abstract:
... The prolonged duration of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has resulted in the continuous emergence of variants of concern (VOC, e.g., Omicron) and variants of interest (VOI, e.g., Lambda). These variants have challenged the protective efficacy of current COVID-19 vaccines, thus calling for the development of novel therapeutics against SARS-CoV-2 and its VO ...

Abstract:
... Microalgae is emerging as a promising platform for the production of recombinant proteins of therapeutic importance. Since microalgae are safe for oral consumption and some microalgal species can form extracellular vesicles, they can potentially be used as edible vaccines or drug-delivery vehicles in addition to their status as naturally rich sources of nutraceutical bioproducts. This article focu ...

Abstract:
... Endo-β-N-acetylglucosaminidases (ENGases) are enzymes that hydrolyze the N-linked oligosaccharides. Many ENGases have already been identified and characterized. However, there are still a few enzymes that have hydrolytic activity toward multibranched complex-type N-glycans on glycoproteins. In this study, one novel ENGase from Bacteroides nordii (Endo-BN) species was identified and characterized. ...

Abstract:
... The expression level of retinol‐binding protein 4 (RBP4) protein is closely related to liver damage and plays an important role in the diagnosis and prognosis of cancer. However, the preparation of anti‐RBP4 mAb or exploration on the application of anti‐RBP4 mAb has not been reported thus far. In the present study, we constructed a pET30a‐RBP4 recombinant vector, used E. coli BL21 (DE3) as the vec ...

Abstract:
... RNase2 is the member of the RNaseA family most abundant in macrophages. Here, we knocked out RNase2 in THP-1 cells and analysed the response to Respiratory Syncytial Virus (RSV). RSV induced RNase2 expression, which significantly enhanced cell survival. Next, by cP-RNAseq sequencing, which amplifies the cyclic-phosphate endonuclease products, we analysed the ncRNA population. Among the ncRNAs accu ...

Abstract:
... For starch metabolism to take place correctly, various enzymes and proteins acting on the starch granule surface are crucial. Recently, two non‐catalytic starch‐binding proteins, pivotal for normal starch turnover in Arabidopsis leaves, namely, EARLY STARVATION 1 (ESV1) and its homolog LIKE EARLY STARVATION 1 (LESV), have been identified. Both share nearly 38% sequence homology. As ESV1 has been f ...

Abstract:
... Mussel foot proteins (Mfps), which help mussels attach to various surfaces, are considered to be promising biomaterials due to their outstanding adhesive properties. However, limited production and lack of post-translational modifications of tyrosine residues into 3,4-dihydroxyphenylalanine (Dopa) in bacterial expression systems have hampered their applications. In the present study, for the first ...
