The congenital absence of teeth, commonly referred to as hypodontia or tooth agenesis, is a common developmental anomaly of human dentition that affects approximately 20% of the population. Although new genetic and molecular approaches in humans and mice have increased our understanding of the molecules that control tooth patterning (number, position, shape and size), the precise nature of the genes involved in hypodontia in humans is poorly understood. Hence, understanding the molecular basis for missing teeth is an issue of paramount importance that is both timely and significant to the practice of dentistry. So far, only two genes have been associated with non-syndromic familial tooth agenesis: MSX1 and PAX9. Substitution mutations in the homeodomain region of MSX1 were linked to premolar agenesis while an insertion mutation in the paired box domain of PAX9 was shown to be responsible for molar oligodontia.. The long-term goals of this research are to elucidate the molecular pathology of ...

The research in the Oestreich Laboratory focuses on defining the mechanisms by which transcription factors contribute to cellular differentiation and function in the immune system. The formation of the immune system is entirely dependent on the ability of numerous cell types to arise from a common progenitor. Developmental transcription factors are necessary for regulating the cell-type-specific gene expression patterns dictating the phenotype of each of these unique cells. Unfortunately, mutations in these key factors often lead to their improper function, resulting in cancer and autoimmune disease. Two such examples that are studied in the laboratory are the T helper cell lineage-defining transcription factors, T-bet and Bcl-6. Aberrant activity of T-bet has been linked to numerous autoimmune diseases including type 1 diabetes, while mutations in Bcl-6 are frequently associated with the onset of lymphoma. Therefore, it is critically important to understand the molecular mechanisms by which these and

Tooth agenesis can involve one or more congenitally missing teeth (CMT) and is the most common congenital dental anomalies in humans. Tooth agenesis and reduction of mesiodistal tooth width are reportedly associated, suggesting that the pathogenesis of the two conditions is related. The current study analyzed the frequency of tooth agenesis and mesiodistal tooth width in cases of hypodontia (1-5 CMT) and oligodontia (≥ 6 CMT) in Japanese patients based on the hypothesis that reductions in mesiodistal tooth width are more frequently associated with oligodontia than hypodontia. Japanese patients with tooth agenesis were divided into hypodontia cases (60 female and 25 male, mean age 19.6 years, mean CMT number 1.31 ± 1.65) and oligodontia cases (26 female and 25 male, mean age 14.6 years, mean CMT number 8.07 ± 2.39). Controls included patients with a skeletal class I relationship and no CMT (female and 60 male, mean age 20.8 years). Dental casts and orthopantomograms were used to analyze the CMT

Ancient metazoan organisms arose from unicellular eukaryotes that had billions of years of genetic evolution behind them. The transcription factor networks present in single-celled ancestors at the origin of the Metazoa (multicellular animals) were already capable of mediating the switching of the unicellular phenotype among alternative states of gene activity in response to environmental conditions. Cell differentiation, therefore, had its roots in phenotypic plasticity, with the ancient regulatory proteins acquiring new targets over time and evolving into the ``developmental transcription factors" (DTFs) of the ``developmental-genetic toolkit." In contrast, the emergence of pattern formation and morphogenesis in the Metazoa had a different trajectory. Aggregation of unicellular metazoan ancestors changed the organisms spatial scale, leading to the first ``dynamical patterning module" (DPM): cell-cell adhesion. Following this, other DPMs (defined as physical forces and processes pertinent to ...

The aim of this study was to investigate the prevalence of tooth agenesis, microdontia, and tooth malformation among non-syndromic oral cleft patients and their potential association with cleft type and gender. Intraoral records and radiographs of 154 patients (97 males and 57 females) were examined. The variables assessed were tooth agenesis, microdontia, dental malformations, and cleft types. The statistics included chi-square and Fishers exact tests as well as logistic regression to assess any mutual effects of gender and cleft type on the dental variables. Tooth agenesis occurred in 50% of the sample and microdontia in 18%. Non-statistically significant odds ratios for the association of gender and cleft type with tooth agenesis were obtained. Tooth agenesis was substantially higher at the unilateral right CL + P and the bilateral CL + P in quadrant 1 and at the unilateral left CL + P and bilateral CL + P in quadrant 2. It was also higher, at the isolated cleft palate (CP) in quadrants 3 and 4.
PAX9, a paired domain transcription factor, has important functions in craniofacial and limb development. Heterozygous mutations of PAX9, including deletion, nonsense, or frameshift mutations that lead to a premature stop codon, and missense mutations, were previously shown to be associated with autosomal dominant oligodontia. Here, we report a novel missense mutation that lies in the highly conserved paired domain of PAX9 and that is associated with non-syndromic oligodontia in one family. The mutation, 83GC, is predicted to result in the substitution of arginine by proline (R28P) in the N-terminal subdomain of PAX9 paired domain. To rule out the possibility that this substitution is a rare polymorphism and to test whether the predicted amino acid substitution disrupts protein-DNA binding, we analyzed the binding of wild-type and mutant PAX9 paired domain to double-stranded DNA targets. The R28P mutation dramatically reduces DNA binding of the PAX9 paired domain and supports the hypothesis ...
We report a comprehensive integrative analysis from multiple large-scale human epigenomic datasets, across methylation, transcription, and chromatin modifications. For the first time we used tests that integrate allelic events across populations linked either to the reference allele or purely to recurrent imbalanced methylation states of chromosomes observable only in population NGS data. We have not only generated the largest catalogue of methylation changes in haploid human genomes, but by combining these three levels of genomic data with allelic profiling, we reveal novel relationships between genetic and non-genetic allelic variation. Non-genetic effects are seen in imprinted regions of the human genome but are also strikingly enriched in classes of developmental transcription factors. The non-genetic variation appears to have less involvement in active allelic chromatin states (28% of functional AS CpG-gene correlations). Our CpG allelic variation catalogue can be utilized to intersect with ...

A pharyngeal pouch is an out-pouching or pocket (diverticulum) that develops from the posterior wall of the pharynx just above the entrance to the oesophagus (gullet). The pouch may develop as the result of a lack of co-ordination in timing and muscle tone within the sphincter muscle at the top of the oesophagus (cricopharyngeus muscle) During the act of swallowing, the muscles of the pharynx contract and pressure in the pharynx increases. If the cricopharyngeus muscle does not open at the appropriate time, pressure builds up immediately above it and the pharyngeal mucosa may herniate through a potential weakness in the posterior wall of the pharynx at Killians dehiscence, between the cricopharyngeus and thyropharyngeus muscles. This results in the development of the pouch.. Patients usually present with symptoms in the sixth and seventh decade of life. Symptoms of pharyngeal pouch vary and small pouches may cause no symptoms at all. However, pouches may give rise to difficulty in swallowing, ...
Congenital heart defects (CHDs) are the most common birth defect worldwide and are a leading cause of neonatal mortality. Nonsyndromic atrioventricular septal defects (AVSDs) are an important subtype of CHDs for which the genetic architecture is poorly understood. We performed exome sequencing in 13 parent-offspring trios and 112 unrelated individuals with nonsyndromic AVSDs and identified five rare missense variants (two of which arose de novo) in the highly conserved gene NR2F2, a very significant enrichment (p = 7.7 × 10(-7)) compared to 5,194 control subjects. We identified three additional CHD-affected families with other variants in NR2F2 including a de novo balanced chromosomal translocation, a de novo substitution disrupting a splice donor site, and a 3 bp duplication that cosegregated in a multiplex family. NR2F2 encodes a pleiotropic developmental transcription factor, and decreased dosage of NR2F2 in mice has been shown to result in abnormal development of atrioventricular septa. Via
The spo0J gene of Bacillus subtilis is required for the initiation of sporulation. We show that the sporulation defect caused by null mutations in spo0J is suppressed by a null mutation in the gene located directly upstream from spo0J, soj (suppressor of spo0J). These results indicate that Soj inhibits the initiation of sporulation and that Spo0J antagonizes that inhibition. Further genetic experiments indicated that Soj ultimately affects sporulation by inhibiting the activation (phosphorylation) of the developmental transcription factor encoded by spo0A. In addition, the temperature-sensitive sporulation phenotype caused by the ftsA279 (spoIIN279) mutation was partly suppressed by the soj null mutation, indicating that FtsA might also affect the activity of Soj. Soj and Spo0J are known to be similar in sequence to a family of proteins involved in plasmid partitioning, including ParA and ParB of prophage P1, SopA and SopB of F, and IncC and KorB of RK2, spo0J was found to be required for normal ...
The focus of my laboratory is the understanding of basic mechanisms that regulate the fate of stem cells within tissues. We are currently studying skin and hair follicle stem cells using cell culture and the mouse as model systems. Hair follicle stem cells reside in their niche in a quiescent state, but become rapidly activated in response to homeostatic and injury signals to regenerate the tissue. We are analyzing the physiological role of several genes implicated in different aspects of stem cell activation, self-renewal, and differentiation. Our general focus is on stem cell fate choice by epigenetic regulation, transcription regulation via specific developmental transcription factors, and chromatin modifying factors. Additionally, we recently began to explore the potential implication of our genes of interest in cancer.. ...
Paired box gene 9, also known as PAX9, is a protein which in humans is encoded by the PAX9 gene. It is also found in other mammals. This gene is a member of the paired box (PAX) family of transcription factors. During mouse embryogenesis Pax9 expression starts from embryonic day 8.5 and becomes more evident by E9.5; at this stage its expression is restricted to the pharyngeal endoderm. Later on, Pax9 is also expressed in the axial skeleton. Pax9 is required for craniofacial, tooth and limb development, and may more generally involve development of stratified squamous epithelia as well as various organs and skeletal elements. PAX9 plays a role in the absence of wisdom teeth in some human populations (possibly along with the less well studied AXIN2 and MSX1). This gene was found amplified in lung cancer. The amplification covers three tissue developmental genes - TTF1, NKX2-8, and PAX9. It appears that certain lung cancer cells select for DNA copy number amplification and increased RNA/protein ...
If you experience any of these symptoms then consult your GP. He or she will refer you to a specialist for further investigation. This is important as there may be an underlying cause of your condition such as a stroke or acid reflux disease. The oesophagus will be examined using a medical imaging technique called barium swallow. This involves swallowing a liquid which leaves a coating on the oesophagus and will enable it to be seen on an X-ray.. This is usually treated by endoscopic surgery although open surgery is another option. The muscle responsible for causing the pouch is incised and the pouch stapled. .BTF_1 { width: 320px; height: 300px; } @media (min-width:500px) { .BTF_1 { width: 468px; height: 300px; } } @media (min-width:800px) { .BTF_1 { width: 600px; height: 300px; } } ...

PAX8 was not only a mitotic factor, but identified as a transcription factor involved in the prognosis of human tumor patients. Elucidating the function of PAX8 on the pathology of stomach cancer was meaningful. PAX8 was found to be upregulated in primary stomach cancer tissue and the TCGA stomach cancer dataset. Interestingly, SOX13 and PAX8 showed consistent expression patterns, and the combined high PAX8 and SOX18 expression induced a worse prognosis of stomach cancer patients. SOX13 was further identified as a transcription factor of PAX8, and further affect Aurora B and Cyclin B1 expression, two cell cycle related factors of the downstream of PAX8, including. Furthermore, PAX8 depletion inducted G1-phase arrest and the decrease of EdU incorporation, cell viability and colony formation can be rescued by SOX13 overexpression. SOX13 participated in the elevated expression of PAX8, which promote the proliferation of stomach cancer cells. Therefore, SOX13 mediated PAX8 expression was recognized as a
