Nephronectin (NPNT) is a Crucial Determinant of Idiopathic Pulmonary Fibrosis: Modulating Cellular Senescence via the ITGA3/YAP1 Signaling Axis

open access: yesAdvanced Science, EarlyView.
Through a comprehensive multi‐omics analysis, this study identifies a marked reduction in Nephronectin (NPNT) expression within fibrotic lung tissue. This reduction impairs the binding capability to the ITGA3 receptor, consequently causing YAP1 to persist in the cytoplasm, where it undergoes degradation.

Chromo-fluorogenic probes for beta-galactosidase detection

open access: yes, 2021
beta-Galactosidase (beta-Gal) is a widely used enzyme as a reporter gene in the field of molecular biology which hydrolyzes the beta-galactosides into monosaccharides. beta-Gal is an essential enzyme in humans and its deficiency or its overexpression results in several rare diseases.

The mechanism of action of beta-galactosidase. Effect of aglycone nature and -deuterium substitution on the hydrolysis of aryl galactosides.

open access: yesBiochemical Journal, 1973
1. Steady-state kinetic parameters for the beta-galactosidase-catalysed hydrolysis of 13 aryl beta-d-galactopyranosides show no simple dependence on aglycone acidity. 2.

Progastrin Promotes Colorectal Cancer Stem Cell‐Like Properties via the Receptor PZR

open access: yesAdvanced Science, EarlyView.
The tumor microenvironment supports colorectal cancer (CRC) progression by maintaining cancer stem cells (CSCs) through progastrin (PG). This study identifies Protein Zero‐Related protein (PZR) as an essential receptor for PG activity, promoting CSC‐like signaling via SHP2/SRC/β‐catenin.

Human iPSCs Derived MSCs‐Secreted Exosomes Modulate Senescent Nucleus Pulposus Cells Induced Macrophage Polarization via Metabolic Reprogramming to Mitigate Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Senescent nucleus pulposus cells drive inflammatory M1 macrophage polarization, exacerbating intervertebral disc degeneration (IDD). Conversely, M1 macrophages accelerate NP cell senescence, creating a vicious cycle. iPSCs‐derived mesenchymal stem cell (iMSCs) exosomes break this loop by delivering miR‐100‐5p to suppress mTORC1/glycolysis in ...

beta-Galactosidase alpha-complementation. Overlapping sequences.

open access: yesJournal of Biological Chemistry, 1981
Enzyme activity is restored to two defective beta-galactosidase molecules (M15 protein lacking amino acid residues 11-41 and M112 protein lacking residues 23-31) by incubation with CNBr2 (residues 3-92 of beta-galactosidase). M15 and M112 proteins (alpha-acceptors) are dimers. Complemented enzyme, like wild type, has a tetrameric structure. Cleavage of

Expression of a preproinsulin-beta-galactosidase gene fusion in mammalian cells.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1983
As an approach to the study of mammalian gene expression, the promoters and translation initiation regions of the rat preproinsulin II and the simian virus 40 early genes were fused to the structural gene of Escherichia coli beta-galactosidase, a ...

β‐Mangostin Attenuates TET2‐Mediated DNA Demethylation of Prkcg in the Prevention of Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
β‐Mangostin alleviates intervertebral disc degeneration through dual modulation of macrophage polarization and the TET2‐Prkcg axis in nucleus pulposus cells. Abstract Intervertebral disc degeneration (IDD) induced lower back pain is a main cause of disability, resulting in a substantial workforce loss worldwide and placing a substantial burden on the ...

Quorum Sensing Inhibits Type III‐A CRISPR‐Cas System Activity Through Repressing Positive Regulators SarA and ArcR in Staphylococcus Aureus

open access: yesAdvanced Science, EarlyView.
This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.
