Hello, Terrypeng and welcome to Wikipedia! It appears you are participating in a class project. If you haven't done so already, we encourage you to go through our training for students. Your instructor or professor may wish to set up a course page, if your class doesn't already have one.

Go through our online training for students.

If you need help, check out Wikipedia:Questions, ask me on my talk page, or ask your question on this page and then place {{Helpme}} before the question.

Before you create an article, make sure you understand what kind of articles are accepted here. Remember: Wikipedia is an encyclopedia, and while many topics are encyclopedic, some things are not.

It is highly recommended that you place this text: {{Educational assignment}} on the talk page of any articles you are working on as part of your Wikipedia-related course assignment. This will let other editors know this article is a subject of an educational assignment and should be treated accordingly.

We hope you like it here and encourage you to stay even after your assignment is finished!

Hey Terry, Awesome job thus far. The articles are really good, and we're going to revolutionize this myogenesis wikipedia page.

Myogenesis Project

edit

Project Topic—Myogenesis

Overview

Myogenesis refers to the process of muscle development. With the integral role that muscles—whether cardiac, smooth, or skeletal—play in the function of many organisms, the study of myogenesis has become a major point of interest in modern biological research. From muscular dystrophy to heart disease, there is a myriad of medical conditions that researchers could potentially better address with increased study and understanding of myogenesis. Unfortunately, the current page for myogenesis (as of February 7th, 2013) relays but a small portion of the findings from myogenic research available on the web. Our goal is to improve both the quantity and quality of information on myogenesis in the Wikipedia community by providing insight from the most reputable, cutting-edge authorities in this field of research. We hope to share a well-constructed, detailed description of myogenesis with all readers in this forum.

Our approach to this project is simple: We aim to provide Wikipedia users with the best possible article by actively seeking the most up-to-date and detailed information from respected sources. Below, we have constructed a summary of the information we intend to include in our project. In addition, we have listed a selection of projected topics to be covered and projected sources to be consulted during our project.

Journal of Clinical Investigation [1]

Regulation of myogenic differentiation is controlled by two pathways, the phosphoinosital 3-kinase/Akt pathway and the Notch/Hes pathway, which work in a collaborative manner to suppress MyoD transcription. The O subfamily of the forkhead proteins (Foxo) play a critical role in regulation of myogenic differentiation as they stabilize the Notch/Hes binding. Research has shown knockout Foxo1 mice, increase MyoD expression, altering distribution of fast-twitch, slow-twitch fibers.

Development 1 [2]

A transcription factor (Tcf4) of connective tissue fibroblasts is involved in the regulation of myogenesis. Specifically it regulates the type of muscle fiber developed and its maturations. Low levels of Tcf4 promote both slow and fast myogenesis, overall promoting the maturation of muscle fiber type. Thereby this shows the close relationship of muscle with connective tissue during the embryonic development.

Development 2 [3]

The Six1 gene of plays a critical role in hypaxial muscle differentiation in myogenesis. In mice lacking this gene sever muscle hypoplasia affected most of the body muscles, specifically hypaxial muscles. Therefore this gene plays a specific role in hypaxial muscle differentiation, distinct from other determinants (Pax3, cMet, Lbx1 or Mox2)

Development 3 [4]

Sim2, a BHLH-Pas transcription factor, inhibits transcription by active repression and displays enhanced expression in ventral limb muscle masses during chick and mouse embryonic development. It accomplishes this by repressing MyoD transcription by binding to the enhancer region, and prevents premature myogenesis.

Nature [5]

Delta1 expression in neural crest cells is necessary for muscle differentiation of the somites, through the Notch signaling pathway. Gain and loss of this ligand in neural crest cells results in delayed or premature myogenesis.

Hindawi Publishing Organization [6]

Skeletal myogenesis depends on the strict regulation of the expression of various gene subsets. bHLH transcription factors like MyoD, Myf5, Myogenin, and Mrf4 are critical to its formation. This specific combination of transcription factors are what cause myblasts differentiating into myotubes.

Stanford Medical School [7]

There are 3 types of proteins produced during myogenesis. Class A proteins are the most abundant and are synthesized continuously throughout myogenesis. Class B proteins are proteins that are initiated during myogenesis and continued throughout development. Class C proteins are those synthesized at specific times during development. Also 3 different forms of actin were identified during myogenesis.

Massachusetts Institute Of Technology [8]

95 alternative splicing events occur during C2C12 differentiation in myogenesis. Therefore alternative splicing is necessary in myogenesis.

Washington University of St. Louis [9]

This source describes the overall process of myogenesis and muscle regeneration. Goes into great detail about all the known genes and proteins that play a role in myogenesis as well as muscle repair. It also goes into detail about the mechanisms involved.

New York University [10]

This source describes the regulatory networks that control myogenic differentiation. It discusses the MyoD and the transcription factors that it works combinatorial with. It also describes skeletal muscle regeneration.
