Human placental neuraminidase. Activation, stabilization and association with beta-galactosidase and its protective protein

, 1985
Supernatant of homogenized human placenta hardly contains lysosomal neuraminidase activity. It is, however, possible to generate remarkably high activity by concentration of a partially purified glycoprotein fraction. This activity is labile to dilution,

The sRNA vvrr1 Modulates the VarS/VarA‐Csr System via LeuO to Regulate Biofilm Formation and Virulence in Vibrio alginolyticus

Animal Research and One Health, EarlyView.
vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

Differences in SARS‐CoV‐2 Antigen Persistence in Individuals With Systemic Autoimmune Rheumatic Diseases Compared to the General Population: A RECOVER‐Adult Cohort Study

Arthritis &Rheumatology, EarlyView.
Objective Individuals with systemic autoimmune rheumatic diseases (SARDs) are at risk for worse acute and post–acute COVID‐19 outcomes, though whether individuals with SARDs have longer persistence of viral antigens after COVID‐19 has not been studied.

Altered expression of beta-galactosidase-1-like protein 3 (Glb1l3) in the retinal pigment epithelium (RPE)-specific 65-kDa protein knockout mouse model of Leber's congenital amaurosis

Purpose: In this study, we investigated the expression of the gene encoding beta-galactosidase (Glb)-1-like protein 3 (Glb1l3), a member of the glycosyl hydrolase 35 family, during retinal degeneration in the retinal pigment epithelium (RPE)-specific 65 ...

Molecular genetic analyses of potential beta-galactosidase genes in Xanthomonas camplestris

, 2014
Xanthomonas campestris pv. campestris, which displays no significant beta-1,4-agalactopyranosidase activity, has three annotated beta-galactosidase genes in the sequenced genome, designated galA, galB and galC herein.

IgG Glycosylation‐Dependent CLEC7A Signaling Drives Podocyte Dysfunction in Lupus Nephritis

Arthritis &Rheumatology, EarlyView.
Objective Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE) that can lead to end‐stage kidney disease and increased mortality. IgG from patients with LN displays abnormal glycosylation, contributing to podocyte injury.

Optimizing Efficacy to Safety Ratio of Glucocorticoids in Rheumatoid Arthritis Models by Leveraging Peroxisome Proliferator–Activated Nuclear Receptor‐α Agonism

Arthritis &Rheumatology, EarlyView.
Objective Glucocorticoids remain essential therapies for immune and inflammatory diseases such as rheumatoid arthritis (RA) but are notorious for their metabolic side effects. Given the anti‐inflammatory and metabolically favorable actions of peroxisome proliferator–activated nuclear receptor (PPAR) agonists, we investigated whether PPARα agonism could

Stabilization by Crosslinking of β‐Galactosidase Immobilized by Adsorption for Application in a Continuous Lactose Removal Process

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Adsorption is the simplest method of enzyme immobilization, but it often requires additional treatments to improve stability. These treatments, however, may impact enzymatic activity. This study investigated the effect of crosslinking on the stability of β‐galactosidase immobilized by adsorption on A‐568 resin and its implications for ...

Species Dynamics and Gene Expression in Algal Polycultures Under Mixotrophic Cultivation in Outdoor Pilot‐Scale Nordic Conditions

Biotechnology and Bioengineering, EarlyView.
These results demonstrate that mixotrophic conditions drive both microbial community shifts and metabolic reprogramming, underscoring the importance of cultivation strategy and polyculture selection for targeted applications such as nutrient recovery and bioproduct generation.
