Stomatognathic functional improvement in a patient with a canted occlusal plane and temporomandibular disorder treated with an edgewise appliance and miniscrews.

Generally, a canted occlusal plane results in esthetic problems, such as an asymmetric mandible with midline deviation, and functional problems, such as temporomandibular disorder (TMD). For many years, orthognathic surgery has been used to level a canted occlusal plane. However, similar effects might be achieved by intruding the posterior teeth using a miniscrew.

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.

The expression of Fn14 via mechanical stress-activated JNK contributes to apoptosis induction in osteoblasts.

Bone mass is maintained by the balance between the activities of bone-forming osteoblasts and bone-resorbing osteoclasts. It is well known that adequate mechanical stress is essential for the maintenance of bone mass, whereas excess mechanical stress induces bone resorption. However, it has not been clarified how osteoblasts respond to different magnitudes of mechanical stress.

N-Myristoylation is essential for protein phosphatases PPM1A and PPM1B to dephosphorylate their physiological substrates in cells.

PPM [metal-dependent protein phosphatase, formerly called PP2C (protein phosphatase 2C)] family members play essential roles in regulating a variety of signalling pathways. While searching for protein phosphatase(s) that act on AMPK (AMP-activated protein kinase), we found that PPM1A and PPM1B are N-myristoylated and that this modification is essential for their ability to dephosphorylate the α subunit of AMPK (AMPKα) in cells. N-Myristoylation was also required for two other functions of PPM1A and PPM1B in cells.
