Direct association of occludin with ZO-1 and its possible involvement in the localization of occludin at tight junctions. [PDF]

The Journal of cell biology, 1994
Occludin is an integral membrane protein localizing at tight junctions (TJ) with four transmembrane domains and a long COOH-terminal cytoplasmic domain (domain E) consisting of 255 amino acids. Immunofluorescence and laser scan microscopy revealed that chick full-length occludin introduced into human and bovine epithelial cells was correctly delivered ...

Mettl3‐Mediated m6A Modification Represents a Novel Therapeutic Target for FSGS

Advanced Science, EarlyView.
This study explores the roles of Mettl3‐induced N6‐methyladenosine (m6A) modifications in Focal segmental glomerulosclerosis (FSGS). The findings reveal that inhibition of Mettl3 results in podocyte injury by modulating the TJP1CDC42 pathway. Moreover, Administration of N6‐methyladenosine attenuates the FSGS phenotype in WT mice induced by Adriamycin ...

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

Hepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.

Circular RNA PTPN4 Contributes to Blood‐Brain Barrier Disruption during Early Epileptogenesis

Advanced Science, EarlyView.
Epileptic condition induces CircPTPN4 upregulation, which promotes ECE‐1 expression through competitive sequestration of miR‐145a‐5p. The elevated ECE‐1 catalyzes the ET‐1 production, leading to p38/MAPK pathway activation and subsequent downregulation of tight junction protein expression. This cascade results in increased BBB permeability and enhanced

The functional antagonist of sphingosine-1-phosphate, FTY720, impairs gut barrier function

Frontiers in Pharmacology
FTY720 or fingolimod is a known functional antagonist of sphingosine-1-phosphate (S1P), and it is effective in treating multiple sclerosis and preventing inflammatory bowel disease (IBD).

17,β-estradiol inhibits hepatitis C virus mainly by interference with the release phase of its life cycle [PDF]

, 2016
Rationale & Aim: Estrogen and estrogen-mediated signalling protect from hepatitis C virus through incompletely understood mechanisms. We aimed to ascertain which phase(s) of HCV life cycle is/are affected by estrogens.

Occludin deficiency with BACE1 elevation in cerebral amyloid angiopathy [PDF]

Neurology, 2014
A significant cause of spontaneous hemorrhages in the elderly is cerebral amyloid angiopathy (CAA), which causes degeneration of cerebral vessels, but the mechanisms are unclear.We isolated leptomeningeal vessels from rapidly autopsied brains (the average of postmortem intervals was 3.28 hours) from 9 patients with CAA and 10 age-matched controls, and ...

Evaluation of Serum Zonulin and Occludin Levels in Bipolar Disorder

Psychiatry Investigation, 2023
Objective The etiology of bipolar disorder (BD) is still not fully understood. Little is currently known about the relationship between the interaction the gastrointestinal system and brain function and BD. Zonulin is the only known physiological modulator of tight junctions and is a biomarker for intestinal permeability (IP).

DRD2 Deficiency Underlies Pituitary Adenoma Dependent on Escherichia coli Translocation from the Gut

Advanced Science, EarlyView.
Dopamine receptor D2 (DRD2) deficiency disrupts epithelial barrier integrity in both the gut and pituitary gland, facilitating translocation of gut‐derived Escherichia coli into pituitary tissue. Intratumoral E. coli are phagocytosed by microglia, triggering GSDMD‐dependent pyroptosis and HMGB1 release, which subsequently activates MAPK signaling to ...
