Oral Cell Engineering Lab

The lab investigates how information is transmitted inside cells, starting from the molecular level.

AboutAbout the lab
Studying intracellular signaling at the molecular level
The Oral Cell Engineering Lab is part of the Department of Normal Oral Function Regulation in the Faculty of Dental Science at Kyushu University, and it studies how information is transmitted inside cells.
Its predecessor was the Department of Oral Biochemistry, established in 1968, which took its current name in the organizational restructuring of 2000.
The lab has examined from many angles the physiological functions of a protein that binds inositol 1,4,5-trisphosphate, which it discovered in 1992.
Its current research themes also include the regulation of bone metabolism by the transcription factor NF-κB.
Key terms
- NF-κB
- A transcription factor that regulates the expression of genes involved in inflammation and immune responses.
- Osteoclasts
- Cells that resorb bone. It has been reported that when estrogen is deficient, bone resorption is enhanced through NF-κB.
ResearchResearch themes
The Oral Cell Engineering Lab studies how information is transmitted inside cells, using cell biology and molecular biology experiments. Its research covers functional analysis of proteins that bind inositol 1,4,5-trisphosphate, and the regulation of bone and metabolism by NF-κB.
*Illustrative imageProteins Responsible for Intracellular Signaling
Using cell biology and molecular biology experiments, the lab studies the roles that inositol phosphates and inositol phospholipids play in intracellular signaling, focusing mainly on functional analysis of proteins that bind inositol 1,4,5-trisphosphate.
*Illustrative imageNF-κB and the Regulation of Bone Metabolism
The lab investigates the molecular basis of how the transcription factor NF-κB regulates bone metabolism, focusing on bone metabolism and osteoclasts. It aims to use the findings to develop new therapeutic strategies.
*Illustrative imagePostmenopausal Bone Loss and Weight Gain
The lab studies the relationship between NF-κB activation under estrogen deficiency and bone loss and weight gain. A published paper has shown that in ovariectomized mice, NF-κB is activated in the metaphysis of long bones and in white adipose tissue.
*Illustrative imageOral Cancer Progression and p65 Modification
Focusing on deamidation of p65, a transcription factor that is part of NF-κB, the lab studies the mechanisms by which oral squamous cell carcinoma progresses.
