Age-related macular degeneration (AMD) is one of the most common leading causes of irreversible blindness, and there is no effective treatment for it. It has been reported that aging is the greatest r...
Ocular, genital, and anogenital infection by the obligate intracellular pathogen...
Junctional epithelium (JE) connects the tooth surface and gingival epithelium and adheres directly to the tooth enamel. JE plays an important role as a barrier preventing the invasion of exogenous bac...
We generated a novel JE cell line, mHAT-JE01, using naturally immortalized dental epithelium derived from incisor labial cervical cells and by selecting cells that adhered to apatite. mHAT-JE01 was ch...
The mHAT-JE01 cells had a higher capacity for producing JE-specific markers than oral mucous epithelial cells. In addition, the presence of lipopolysaccharides from Porphyromonas gingivalis downregula...
This cell line is stable and presents the opportunity to characterize JE efficiently, which is essential for the prevention and treatment of periodontal disease....
In early 2020, the novel pathogenic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China, and rapidly propagated worldwide causing a global health emergency. SARS-CoV-2...
Mitophagy may have a potential role in the pathogenesis of acquired cholesteatoma....
Enhanced mitophagy has been proven to be involved in various cancers. However, its role in the pathogenesis of cholesteatoma, which shares some common features with cancer, is controversial. This stud...
The autophagy protein markers LC3-II and p62 and mitophagy proteins BNIP3, Parkin, and PINK1 were analyzed in cholesteatoma epithelial cells and external auditory canal epithelium cells by immunoblott...
LC3-II expression was increased in cholesteatoma cells, whereas soluble and insoluble p62 levels were decreased. The expressions of BNIP3, Parkin, and PINK1 were higher in total protein and mitochondr...
Mitophagy was enhanced in cholesteatoma epithelial cells and may have a potential role in the pathogenesis of acquired cholesteatoma....
Neurons and epithelia are viewed as fundamentally different cell types, yet some sensory neurons exhibit hallmarks of epithelial cells. For example, they use tight junctions to form a diffusion barrie...
Epithelial-Mesenchymal Transition (EMT) of retinal pigment epithelial (RPE) cells is recognized as pivotal in various retinal diseases. Previous studies have suggested a reciprocal regulation between ...
During enamel formation, transforming growth factor-beta (TGF-β) isoforms exhibit different activities for gene expression, apoptosis, and endocytosis. This study aimed to investigate the differential...
Using a mouse enamel epithelial cell line (mHAT9d) cultured in the presence of each TGF-β isoform, (1) the morphological changes in EMT were explored, (2) EMT-related genes were analyzed by next-gener...
EMT was observed in mHAT9d cultured in the presence of TGF-β1 and β3 but not TGF-β2. The expression of both epithelial and mesenchymal marker genes was observed in mHAT9d exhibiting EMT. NGS analysis ...
We propose that in TGF-β-stimulated enamel epithelial cells, EMT mainly occurred via the Rho signaling pathway, and the differences in response across TGF-β isoforms were due to their endoglin-mediate...
Human amniotic epithelial cells (hAECs), which are a type of placental stem cell, express stem cell marker genes and are capable of differentiating into all three germ layers under appropriate culture...
Renal Cell Carcinoma (RCC) is the most common form of all renal cancer cases, and well-known for its highly aggressive metastatic behavior. SMOC2 is a recently described non-structural component of th...
