Evolution and divergence of the role of plant ethylene receptor-related histidine kinases in abscisic acid signaling.

Plant responses to the water environment are mediated by ethylene (submergence response) and abscisic acid (ABA, drought response). Ethylene is perceived by a family of histidine kinase receptors (ETR-HKs), which regulate the activity of the downstream B3 Raf-like (RAF) kinase CONSTITUTIVE TRIPLE RESPONSE1 (CTR1) in an ethylene-dependent manner. We previously demonstrated in the moss Physcomitrium patens that SNF1-related protein kinase 2 (SnRK2), an essential kinase in osmostress responses in land plants, is activated by the B3-RAF kinase ARK, which is also regulated by ETR-HKs in an ABA- and osmostress-dependent manner.

Mechanical loading-induced alveolar bone remodeling is suppressed in the diabetic state via the impairment of the specificity protein 1/vascular endothelial growth factor (SP1/VEGF) axis.

Aims/introduction: Orthodontic treatment involves alveolar bone remodeling in response to mechanical loading, resulting in tooth movement through traction-side bone formation and compression-side bone resorption. However, there are conflicting reports regarding alveolar bone resorption during the orthodontic treatment of patients with diabetes.

Materials And Methods: Diabetes was induced in 8-week-old C56BL/6J mice using streptozotocin (STZ).

Impacts of Hyperglycemia on Epigenetic Modifications in Human Gingival Fibroblasts and Gingiva in Diabetic Rats.

Periodontal disease is considered one of the diabetic complications with high morbidity and severity. Recent studies demonstrated the involvement of the epigenome on diabetic complications. Histone modifications change chromatin architecture and gene activation.

Variation in Diffusion Tensor Imaging Parameters in the Cervical and Thoracic Spinal Cord (C1-C5 and C6-T2) Segments of Normal Beagle Dogs.

This study aimed to determine the characteristics and reference values of each vertebra in the cervicothoracic region by performing diffusion tensor imaging (DTI) scans and analyzing DTI parameters in normal Beagle dogs. In five adult Beagles under anesthetic maintenance, DTI was performed using a 1.5-T magnetic resonance imaging (MRI) scanner.
