Xylt1 is an essential gene in regards to chondrocytes and proper skeletal formation, and is a key factor in the close regulation of maturation. However, the mutation pug of the Xylt1 gene was studied in mice in 2014 and was found to cause the pre-maturation of chondrocytes.
A spotted gar larva at 22 days stained for cartilage (blue) and bone (red). Chondrogenesis is the biological process through which cartilage tissue is formed and developed. . This intricate and tightly regulated cellular differentiation pathway plays a crucial role in skeletal development, as cartilage serves as a fundamental component of the embryonic skele
Collagen alpha-1(X) chain is a protein that in humans is a member of the collagen family encoded by the COL10A1 gene. [5] [6] This gene encodes the alpha chain of type X collagen, a short chain collagen expressed by hypertrophic chondrocytes during endochondral ossification. Unlike type VIII collagen, the other short chain collagen, type X ...
SOX-9 recognizes the sequence CCTTGAG along with other members of the HMG-box class DNA-binding proteins. It is expressed by proliferating but not hypertrophic chondrocytes that is essential for differentiation of precursor cells into chondrocytes [7] and, with steroidogenic factor 1, regulates transcription of the anti-Müllerian hormone gene.
While the DNA sequence of most cells of an organism is the same, the binding patterns of transcription factors and the corresponding gene expression patterns are different. To a large extent, differences in transcription factor binding are determined by the chromatin accessibility of their binding sites through histone modification and/or ...
Transcription factor Sp7, also called Osterix (Osx), is a protein that in humans is encoded by the SP7 gene. [5] It is a member of the Sp family of zinc-finger transcription factors [5] It is highly conserved among bone-forming vertebrate species [6] [7] It plays a major role, along with Runx2 and Dlx5 in driving the differentiation of mesenchymal precursor cells into osteoblasts and ...
Gene structure is the organisation of specialised sequence elements within a gene. Genes contain most of the information necessary for living cells to survive and reproduce. [ 1 ] [ 2 ] In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.
Furthermore, Runx2 controls the gene expression of cyclin D2, D3, and the CDK inhibitor p21(cip1) in hematopoietic cells. It has been shown that on a molecular level, Runx associates with the cdc2 partner cyclin B1 during mitosis. [10] The phosphorylation state of Runx2 also mediates its DNA-binding activity.
