Zhang receives a grant from NIDCR R01 to study genes involved in amelogenesis imperfecta

October 31, 2023
Amelogenesis imperfecta is a condition resulting from hereditary factors that lead to the malformation of enamel, compromising the protective barrier of our teeth. This malformation primarily arises due to mutations in genes that encode enamel matrix proteins. Dr. Zhang, backed by the National...

U.S. Children's Plasma Fluoride Levels Linked to Inflammation Indicators

October 31, 2023
Previous research has shown that fluoride ingestion can increase inflammation markers in rodents. However, making direct comparisons between rodent and human studies has been problematic because of the much higher water fluoride concentrations required for rodents.

Amelogenin Gene's miRNA: A New Hope for Bone Growth Regulation

October 31, 2023
In a recent study, Yakano and coworkers explored the role of the amelogenin gene, which produces the amelogenin protein crucial for enamel formation. Our findings revealed that miR-exon4, a miRNA originating from exon4 of the amelogenin gene, targets the transcription factor nuclear factor I/A (NFI...

Dental Decay is Linked to Blood Infections in Children Receiving Stem Cell Transplants

October 31, 2023
Hematopoietic cell transplantation (HCT) offers a potential cure for various pediatric diseases, but complications like blood stream infections (BSI) pose significant risks. There's emerging evidence linking the oral microbiome, specifically bacteria such as S. mitis, to the onset of BSI.  In a...

COHR researchers found that fluoride targets Androgen Receptor (AR) and Progesterone Receptor (PR) driven Klk4 transcription in maturation ameloblasts

July 03, 2017
Kallikrein related peptidase 4 (KLK4) is thought to play important role in the final stage of dental enamel formation by allowing for enamel crystal growth. In humans having a mutated KLK4 gene and in mice lacking Klk4 expression, the enamel becomes hypomineralized or hypomatured with discoloration...

Paving the way toward tooth regeneration

July 03, 2017
Enamel, formed by ameloblast cells, is the hardest substance in human body, and the first defensive line for healthy tooth. Unfortunately, nearly 40% the incisor teeth in babies and children have some sort of enamel defect. To replace enamel, or even entire teeth, we need strategies to regenerate...

Dr. Ann George visited COHR from University of Illinois, Chicago

May 16, 2016
Dr. Ann George visited COHR on April, 2016 from the University of Illinois and gave the lecture on the topic "DMP1: A busy protein that functions in mineralized matrix assembly". Dr. George is a Professor at the  Division of Oral Biology, University of Illinois, and an Allan G.

COHR researchers found a novel microRNA derived from amelogenin gene, which directs ameloblast and osteoblast differentiation.

January 20, 2016
Amelogenins are the most abundant proteins in the developing enamel matrix, and the gene coding amelogenin is known to be highly alternatively spliced. The researchers from COHR have found that a novel microRNA (miRNA) is derived from amelogenin exon4 through the alternative splicing of amelogenin...
