Ten-m/Odz3 regulates migration and differentiation of chondrogenic ATDC5 cells via RhoA-mediated actin reorganization.

Tenascin-like molecule major (Ten-m)/odd Oz (Odz), a type II transmembrane molecule, is well known to modulate neural development. We have reported that Ten-m/Odz3 is expressed in cartilaginous tissues and cells. Actin cytoskeleton and its regulator ras homolog gene family member A (RhoA) are closely associated with chondrogenesis.

Methionine Enkephalin Suppresses Osteocyte Apoptosis Induced by Compressive Force through Regulation of Nuclear Translocation of NFATc1.

Mechanical stress stimulates bone remodeling, which occurs through bone formation and resorption, resulting in bone adaptation in response to the mechanical stress. Osteocytes perceive mechanical stress loaded to bones and promote bone remodeling through various cellular processes. Osteocyte apoptosis is considered a cellular process to induce bone resorption during mechanical stress-induced bone remodeling, but the underlying molecular mechanisms are not fully understood.

Improvement of Open Bite and Stomatognathic Function in an Axenfeld- Rieger Syndrome Patient by Orthodontic Sectional Arch Mechanics: Clinical Considerations and the Risk of Orthodontic Tooth Movement.

Orthodontists need to understand the orthodontic risks associated with systemic disorders. Axenfeld-Rieger syndrome (ARS) is a rare autosomal dominant disorder with genetic and morphological variability. The risks of orthodontic treatment in ARS patients have been unclear.

Insulin-like growth factor 1 modulates bioengineered tooth morphogenesis.

Regenerative therapy to replace missing teeth is a critical area of research. Functional bioengineered teeth have been produced by the organ germ method using mouse tooth germ cells. However, these bioengineered teeth are significantly smaller in size and exhibit an abnormal crown shape when compared with natural teeth.

Differentiation of Odontoblast-Like Cells From Mouse Induced Pluripotent Stem Cells by Pax9 and Bmp4 Transfection.

Unlabelled: The field of tooth regeneration has progressed in recent years, and human tooth regeneration could become viable in the future. Because induced pluripotent stem (iPS) cells can differentiate into odontogenic cells given appropriate conditions, iPS cells are a potential cell source for tooth regeneration. However, a definitive method to induce iPS cell-derived odontogenic cells has not been established.

Molecular cloning and bacterial expression of the catalytic domain of the SENP1 gene of Oryzias latipes.

In this study, we cloned the catalytic domain of the Oryzias latipes sentrin/SUMO-specific protease 1 (OlSENP1-CD) gene and produced the recombinant OlSENP1-CD protein in Escherichia coli. Experimental procedures designed to reveal the ability of the recombinant protein to show deSUMOylating activity in vitro should be helpful in future studies of other SENPs and the SUMO pathway.

Identification of four SUMO paralogs in the medaka fish, Oryzias latipes, and their classification into two subfamilies.

At least four paralogs of the small ubiquitin-related modifier (SUMO) exist in humans, but there is limited information about SUMO paralogs from other vertebrate species. We isolated the four cDNA encoding proteins, similar to human SUMOs, from the medaka fish, Oryzias latipes: OlSUMO-1, OlSUMO-2, OlSUMO-3, and OlSUMO-4. The amino acid sequences of OlSUMO-2, -3, and -4 are 89-94% identical, but they share only 45% identity with OlSUMO-1.
