Background/purpose: Peroxisome proliferator-activated receptor γ (PPARγ) is a major transcription factor of energy metabolism-associated genes, and three PPARγ isoforms have been identified in periodontal tissues and cells. When energy metabolism homeostasis is affected by PPARγ downregulation in periodontal ligament fibroblasts (PDLFs), osteo/cementogenic abilities are markedly lost. Herein, we investigated whether PPARγ agonists promote periodontal tissue regeneration, and which PPARγ isoforms and metabolic pathways are indispensable for osteo/cementogenic abilities.

Hypophosphatasia (HPP) is an inherited error in metabolism resulting from loss-of-function variants in the gene, which encodes tissue-nonspecific alkaline phosphatase (TNAP). TNAP plays a crucial role in biomineralization of bones and teeth, in part by reducing levels of inorganic pyrophosphate (PP), an inhibitor of biomineralization. HPP onset in childhood contributes to rickets, including growth plate defects and impaired growth.

The biosynthesis of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), which are essential for sesquiterpenes and triterpenes, respectively, is primarily governed by the mevalonate pathway, wherein () plays a pivotal role. This study identified eight members of the FPS gene family in , designated -, through bioinformatics analysis, revealing their distribution across several chromosomes and a notable tandem gene cluster. The genes exhibited strong hydrophilic properties and key functional motifs crucial for enzyme activity.

Calcium phosphates, notably monetite, are valued biomaterials for bone applications owing to their osteogenic properties and rapid uptake by bone cells. This study investigates the enhancement of these properties through Cobalt doping, which is known to induce hypoxia and promote bone cell differentiation. Heat treatments at 700°C, 900°C, and 1050°C are applied to both monetite and Cobalt-doped monetite, facilitating the development of purer, more crystalline phases with varied particle sizes and optimized cellular responses.
