The number of chondrocyte cells created and their maturation process can be influenced by multiple different genes and proteins. Two proteins, bone morphogenetic protein 4(BMP-4) and fibroblast growth factor 2(FGF2) have been seen to influence the amount of differentiation into chondrocytes. [4]
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.
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 ...
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 ...
FERM, RhoGEF and pleckstrin domain-containing protein 1 is a protein that in humans is encoded by the FARP1 gene. [5] [6]This gene was originally isolated through subtractive hybridization due to its increased expression in differentiated chondrocytes versus dedifferentiated chondrocytes.
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.
The protein encoded by this gene has sequence homology to members of the histone deacetylase family. This gene is orthologous to mouse HDAC7 gene whose protein promotes repression mediated via transcriptional corepressor SMRT. Multiple alternatively spliced transcript variants encoding several isoforms have been found for this gene. [7]
