Objective(s:Cleft lip/palate are common congenital anomalies, affecting approximately 2/1000 live births. Pierre Robin Sequence is a subgroup of the cleft palate population. Chromosomal abnormalities near the SOX9 gene disrupt the regulation of this gene and prevent the SOX9 protein from properly controlling the development of facial structures, which leads to isolated PRS. The present study wa...
Fibrosis and organ failure is a common endpoint for many chronic liver diseases. Much is known about the upstream inflammatory mechanisms provoking fibrosis and downstream potential for tissue remodeling. However, less is known about the transcriptional regulation in vivo governing fibrotic matrix deposition by liver myofibroblasts. This gap in understanding has hampered molecular predictions o...
Introduction: Damage to the hyaline layer of large joints resulting from injuries or age-related changes restricts their mobility. The repair these disorders is an actual issue in medicine. One promising therapies usage cell engineering constructs based on a biodegradable scaffold and modified culture. A frequently used method modify proliferation culture for tissue cartilage, which makes it po...
Çamptomelic dysplasia is a fatal infantile dysplasia characterized by lower limb bowing and mesomelic dwarfism. Most of this skeletal dysplasia occur through spontaneous mutation, but recessive autosomic recession is also likely. Prenatal diagnosis is considered with ultrasonography and amniocentesis. Postnatal diagnosis is characterized by mesomelic dwarfism with limb bowing, pulmonary h...
One major unresolved question in the field of pancreas biology is whether ductal cells have the ability to generate insulin-producing β-cells. Conclusive examination of this question has been limited by the lack of appropriate tools to efficiently and specifically label ductal cells in vivo. We generated Sox9CreER(T2) mice, which, during adulthood, allow for labeling of an average of 70% of pan...
TAK1 is a MAP3K that mediates non-canonical TGF-β and BMP signaling. During the embryonic period, TAK1 is essential for cartilage and joint development as deletion of Tak1 in chondro-osteo progenitor cells leads to severe chondrodysplasia with defects in both chondrocyte proliferation and maturation. We have investigated the role of TAK1 in committed chondrocytes during early postnatal developm...
In mammals, birds and reptiles the morphological development of the gonads appear to be conserved. This conservation is evident despite the different sex determining switches employed by these vertebrate groups. Mammals exhibit chromosomal sex determination (CSD) where the key sex determining switch is the Y-linked gene, SRY. Although SRY is the trigger for testis determination in mammals, it i...
Aggressive lethal prostate cancer is characterised by tumour invasion, metastasis and androgen resistance. Understanding the mechanisms by which localised disease progresses to advanced lethal stages is key to the development of effective therapies. Here we have identified a novel role for the transcription factor, SOX9, as a driver of aggressive invasive prostate cancer. Using genetically modi...
OBJECTIVE To identify genes expressed early in the formation of the mouse trachea that control patterning of tracheal cartilaginous rings. DESIGN The mouse larynx and trachea begin as an outpouching from the ventral foregut endoderm at embryonic day (E) 9. Digoxigenin-labeled RNA probes to putative tracheal patterning genes were generated by in vitro transcription. Embryos ranging in age from...
Tumor initiation in the intestine can rapidly occur from Lgr5(+) crypt columnar stem cells. Dclk1 is a marker of differentiated Tuft cells and, when coexpressed with Lgr5, also marks intestinal cancer stem cells. Here, we show that Elp3, the catalytic subunit of the Elongator complex, is required for Wnt-driven intestinal tumor initiation and radiation-induced regeneration by maintaining a subp...
