Claudin-9 constitutes tight junctions of folliculo-stellate cells in the anterior pituitary gland

open access: yesScientific Reports, 2021
The anterior pituitary gland regulates growth, metabolism, and reproduction by secreting hormones. Folliculo-stellate (FS) cells are non-endocrine cells located among hormone-producing cells in the anterior pituitary glands.

Tricellulin constitutes a novel barrier at tricellular contacts of epithelial cells [PDF]

open access: yesThe Journal of Cell Biology, 2005
For epithelia to function as barriers, the intercellular space must be sealed. Sealing two adjacent cells at bicellular tight junctions (bTJs) is well described with the discovery of the claudins. Yet, there are still barrier weak points at tricellular contacts, where three cells join together. In this study, we identify tricellulin, the first integral

Ectoplasmic specialization: A friend or a foe of spermatogenesis? [PDF]

open access: yes, 2007
The ectoplasmic specialization (ES) is a testis-specific, actin-based hybrid anchoring and tight junction. It is confined to the interface between Sertoli cells at the blood-testis barrier, known as the basal ES, as well as between Sertoli cells and ...

The tight junction protein claudin-1 influences cranial neural crest cell emigration [PDF]

open access: yes, 2012
The neural crest is a population of migratory cells that follows specific pathways during development, eventually differentiating to form parts of the face, heart, and peripheral nervous system, the latter of which includes contributions from placodal ...

Tricellulin in Crohn's disease and ulcerative colitis

open access: yesThe FASEB Journal, 2010
The tight junction (TJ) protein tricellulina (TRIC) is predominantly located in tricellular TJs (tTJ), the meeting points of three cells. There it forms a barrier to macromolecules without affecting ion permeability. However, at low TRIC levels the tTJ forms a pathway for macromolecules.

MarvelD3 regulates the c-Jun N-terminal kinase pathway during eye development in Xenopus. [PDF]

open access: yes, 2016
Ocular morphogenesis requires several signalling pathways controlling the expression of transcription factors and cell-cycle regulators. However, despite a well-known mechanism, the dialogue between those signals and factors remains to be unveiled. Here,

Tricellulin and its role in the epididymal epithelium of the rat.

open access: yesBiology of reproduction, 2016
Tricellulin is a tight-junction protein present at tricellular tight junctions. It has been suggested that basal cells are implicated in the blood-epididymis barrier. Basal cells express claudins, a component of tight junctions; however, there is no information regarding the potential architecture or regulation of basal cell-principal cell interactions.

Association of tricellulin expression with poor colorectal cancer prognosis and metastasis

open access: yesOncology Reports, 2020
Tricellulin is a tight‑junction transmembrane protein that regulates cell‑cell interactions. Altered tricellulin expression could promote tumor cell invasions and metastasis in human cancers. The present study assessed tricellulin expression in colorectal cancer tissues for any association with clinicopathological features of colorectal cancer patients

Human peritoneal tight junction, transporter and channel expression in health and kidney failure, and associated solute transport

open access: yesScientific Reports, 2023
Next to the skin, the peritoneum is the largest human organ, essentially involved in abdominal health and disease states, but information on peritoneal paracellular tight junctions and transcellular channels and transporters relative to peritoneal ...
