Modification of β-galactosidase for use in organic mono-phase hexanol system

Macedonian Journal of Chemistry and Chemical Engineering, 2009
Different methods for preparation of the Aspergillus oryzae β-galactosidase were evaluated and the total enzyme activity was determined in hexanol mono-phase system using p-nitrophenyl-β-D-galactoside as a substrate.

A rapid permeabilization procedure for accurate quantitative determination of β-galactosidase activity in yeast cells [PDF]

FEMS Microbiology Letters, 1995
A procedure is described which allows the rapid permeabilization of yeast cells, Schizosaccharomyces pombe and Saccharomyces cerevisiae, for quantitative in situ assays of beta-galactosidase activity. Yeast cells are permeabilized by incubation in buffer containing 0.2% of the detergent sodium lauroyl sarcosinate without any need for washing or ...

Identification of a Hypothetical Protein of Plant Pathogenic Xanthomonas campestris as a Novel β-galactosidase [PDF]

, 2010
[[abstract]]Xc17L, a lactose-utilizing mutant of Xanthomonas campestris pv. campestris previously isolated by mutagenesis with nitrous acid, displays a level of β-galactosidase 3.5-fold higher than that in the parental Xc17.

Targeting p21‐High Senescent Kupffer Cells Nanotherapeutically Potentiates Antitumor Immunity in Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

Advanced Science, EarlyView.
Schematic illustration of a biomimetic SKEV@AAV platform targeting p21‐high senescent Kupffer cells (sKCs) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). p21‐high sKCs accumulate in the PVTT microenvironment and establish an immunosuppressive, SASP‐rich environment that facilitates tumor cell proliferation and immune evasion.

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

Hepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

HMGCR‐Driven Cholesterol Metabolism Promotes Osteoarthritis Progression by Accelerating Synovial Fibroblast Senescence

Advanced Science, EarlyView.
In the pathological context of osteoarthritis (OA), the phosphorylation of AKT1 at Ser473 enhances its binding to Lys140 of Insig1, which facilitates the formation of AKT1–Insig1 complex. Subsequently, the activation of AKT1 promotes the phosphorylation of Insig1 at Ser189, potentially enhancing the dissociation of Insig1 from sterol regulatory element‑

IL‐31 levels correlate with pruritus in patients with cholestatic and metabolic liver diseases and is farnesoid X receptor responsive in NASH

Hepatology, EarlyView., 2022
IL‐31 levels correlate with pruritus in patients with cholestatic and metabolic liver diseases Abstract Background and Aims Pruritus is associated with multiple liver diseases, particularly those with cholestasis, but the mechanism remains incompletely understood.

TET1 Inhibition Promotes Therapeutic Sensitivity in TP53‐Mutant GBM by Influencing Genome Fragility and Altering TAMs Biology

Advanced Science, EarlyView.
In TP53mut GBM cells, reduced P53 function is associated with increased TET1 expression. Genetic or pharmacological inhibition of TET1 correlates with genome fragility, including DNA damage, cellular senescence, telomere shortening, and reactive oxygen species accumulation, which may contribute to increased efficacy of antitumor therapy.

Low copy number vectors for expression of fused genes to β-galactosidase inEscherichia coli [PDF]

FEMS Microbiology Letters, 1991
A series of six expression vectors, pXM184Lac.A, B, C, pXM184Z.A, B, C, based on the low copy plasmid pACYC184 that allow for expression of proteins fused to beta-galactosidase in Escherichia coli is described. A level of 50,000 units of beta-galactosidase is routinely observed and is easily identifiable on protein gels.
