What is PAX7 used for?
What is PAX7 used for?
Pax7 is a transcription factor that plays a role in myogenesis through regulation of muscle precursor cells proliferation. It can bind to DNA as an heterodimer with PAX3. Also interacts with PAXBP1; the interaction links PAX7 to a WDR5-containing histone methyltransferase complex By similarity.
What is PAX7 gene?
PAX7 (Paired Box 7) is a Protein Coding gene. Diseases associated with PAX7 include Myopathy, Congenital, Progressive, With Scoliosis and Rhabdomyosarcoma 2. Among its related pathways are Mesenchymal Stem Cells and Lineage-specific Markers and Neural Crest Differentiation.
Where is the PAX3 gene located?
The human PAX3 gene is located in the 2q36. 1 chromosomal region, and contains 10 exons within a 100 kb region.
What cells express Pax7?
Skeletal muscle growth and regeneration are attributed to satellite cells – muscle stem cells resident beneath the basal lamina that surrounds each myofibre. Quiescent satellite cells express the transcription factor Pax7 and when activated, coexpress Pax7 with MyoD.
Do myoblasts express Pax7?
(A) Pax7 was expressed at high levels in proliferating wild-type myoblasts (Wt-Mb) and MyoD-deficient cells (MyoD−/− Mb) cells and downregulated in response to differentiation conditions (Wt-D and MyoD−/− D). (B) Expression of Pax7 was specific to myogenic cells, with low levels detected in C2C12 myoblasts.
How does the MyoD protein work?
MyoD, also known as myoblast determination protein 1, is a protein in animals that plays a major role in regulating muscle differentiation. The effect of MyoD on satellite cells is dose-dependent; high MyoD expression represses cell renewal, promotes terminal differentiation and can induce apoptosis.
Is PAX6 a Hox gene?
Paired box protein Pax-6, also known as aniridia type II protein (AN2) or oculorhombin, is a protein that in humans is encoded by the PAX6 gene….

What are the symptoms of Waardenburg syndrome?
Symptoms may include:
- Cleft lip (rare)
- Constipation.
- Deafness (more common in type II disease)
- Extremely pale blue eyes or eye colors that don’t match (heterochromia)
- Pale color skin, hair, and eyes (partial albinism)
- Difficulty completely straightening joints.
- Possible slight decrease in intellectual function.
Do C2C12 cells express Pax7?
Rather, Pax7 was strictly expressed in myogenic cells, including low levels in proliferating C2C12 mouse myoblasts, which is a continuous cell line originally derived from satellite cells (Figure 1B).
What tissue is induced by MyoD?
skeletal muscle cells
2 Basic Helix-Loop-Helix Proteins The MyoD family members activate the expression of muscle-specific genes in skeletal muscle cells by binding to a CAXXTG sequence, which is known as the E-box.
How is MyoD regulated?
According to this model the ability of MyoD to activate gene expression is regulated by the antagonistic activities of PcG (Ezh2) and TrxG (Ash2L/MLL2 and UTX) through a mechanism mediated by the transcriptional activators Mef2d, Six4 and modulated by p38α MAPK signaling.
What chromosome is PAX6 on?
The PAX6 gene is located in a region of chromosome 11 that is deleted in people with WAGR syndrome, which is a disorder that affects many body systems and is named for its main features: a childhood kidney cancer known as Wilms tumor, an eye problem called anirida, genitourinary anomalies, and intellectual disability ( …
Where does PAX7 play a role in gastrulation?
Pax-7 plays a role in neural crest development and gastrulation, and it is an important factor in the expression of neural crest markers such as Slug, Sox9, Sox10 and HNK-1. PAX7 is expressed in the palatal shelf of the maxilla, Meckel’s cartilage, mesencephalon, nasal cavity, nasal epithelium, nasal capsule and pons .
Where is PAX7 expressed in the human body?
PAX7 is expressed in the palatal shelf of the maxilla, Meckel’s cartilage, mesencephalon, nasal cavity, nasal epithelium, nasal capsule and pons. Pax7 is a transcription factor that plays a role in myogenesis through regulation of muscle precursor cells proliferation. It can bind to DNA as an heterodimer with PAX3.
How does PAX7 play a role in myogenesis?

Is there a need for Pax7 in spermatogonia?
However, PAX7 is not required for spermatogenesis, as mice without PAX7 + spermatogonia show no deficits in fertility. PAX7 may also function in the recovery in spermatogenesis. Unlike other spermatogonia, PAX7 + spermatogonia are resistant to radiation and chemotherapy.
