Recommendations on Arrangement, Citations

Upon review of the Eukaryotic Cytoskeleton section, I found the article to be informative and well-organized. The Comparison table was especially helpful in summarizing the information, and I believe that an Intro Biology course could greatly benefit from this kind of set-up. All of the subheadings are explored evenly and in-depth, making the article concise but not too technical.

The way that yeast is featured is a bit awkward. While yeast is a unique eukaryote, the way that the information is presented with all of the other elements of presumably every eukaryotic cytoskeleton makes the yeast almost seem like it is not a separate entity. The material is included in a list of components of the eukaryotic cytoskeleton. Is there a better place for this subheading? Perhaps since yeast is a model organism, this could appear within the introductory paragraph of the section.

The Prokaryotic Cytoskeleton Section is also well-organized and beneficial to introductory courses. Because the prokaryotic cytoskeleton may not be covered as in depth as the eukaryotic cytoskeleton, the comparison section helps tie the two together and relate a familiar subject with lesser known information.

Where does the information about FtsZ come from? The article does not list a source within the subheading. The information is presented well, but the lack of citation is concerning.

Microtrabeculae can not be listed at the same level of importance as microtubules, microfilaments and intermediate filaments? According to the article they don't exist, and were simply artefacts of the fixation process used. I really don't think we need to include them at all. -DrNixon 21:22, 25 March 2006 (UTC)

Yep, I totally agree they should be de-emphasized. --Splette ^Talk 13:06, 26 March 2006 (UTC)

i would like to know if the cytoskeleton is the same thing as the cell membrane/wall. —Preceding unsigned comment added by 68.10.87.157 (talk) 02:03, 6 November 2009 (UTC)

Not the same. The "cell membrane" (or "plasma membrane") is the external boundary of the cytosol (the "inside" of the cell); the "cell wall" is one of a variety of more rigid outer wall structures (outside the cell membrane) found in most bacteria and archaea and many eukarya, excluding animals; the cytoskeleton describes a variety of filamentous structures within the cytosol. FredV (talk) 13:42, 9 October 2017 (UTC)

The history section should be placed at the top of this article after the overview. Also more information can be added on the types of cytoskeleton and a generally function of cytoskeleton on a hold should be in the overview of the article. The article needs more pictures(Ancharles002 (talk) 01:53, 23 October 2015 (UTC)).

I do disagree. I expect that most people who look up scientific concepts will be more interested in the concept itself than its history, so it makes sense if the history comes later. Also, the history section is so far from complete that it does not make much sense on the top of the article. The other sections are not complete either, but at least they link to other, more extensive and relevant articles. True, images would be nice. Gormfull (talk) 08:49, 24 October 2015 (UTC)

I will be making a few edits to this article, I am doing this for a course I am taking. I would appreciate some feedback and also some assistance where deemed necessary. I must admit that this article is very difficult to edit,as it is clear what needs to be changed but finding the right information and tone is a challenge.Ancharles002 (talk) 16:02, 14 November 2015 (UTC)

Microfilaments

The header listed 3 kinds of skeletal element but only had paragraphs on 2 of them. The subsequent Intermediate Filament paragraph made reference to their being thicker than actin filaments, but this came out of thin air, as if there was a preceding reference to actin that was somehow missing. So I've added a sketchy para; feel free to extend. — Preceding unsigned comment added by Allangmiller (talk • contribs) 11:03, 9 December 2010 (UTC)

From Wikipedia article on Nikolai Koltsov: "In 1903 Koltsov proposed that the shape of cells was determined by a network of tubules which he termed the cytoskeleton." Twill0001 (talk) 17:54, 19 July 2011 (UTC)

Ivan Denisov (talk) 06:51, 3 September 2011 (UTC) Attantion: The Wiki paper http://en.wikipedia.org/wiki/Cytoskeleton has hard error "The concept of a protein mosaic that dynamically coordinated cytoplasmic biochemistry was proposed by Rudolph Peters in 1929 [1] while the term (cytosquelette, in French) was first introduced by French embryologist Paul Wintrebert in 1931.[2]". Exact info:"In 1903 Nikolai K Koltsov proposed that the shape of cells was determined by a network of tubules which he termed the cytoskeleton". http://en.wikipedia.org/wiki/Nikolai_Koltsov Peter I Belobrov checkit this info in 2010 & confirm this fact by the publication of N K Koltsov. More them Koltsov's cytoskeleton was very popular far before 1929 as there is into a few classical text book on biology of early 20th century. http://ia700301.us.archive.org/10/items/ongrowthform00thom/ongrowthform00thom.djvu http://www.nature.com/nrg/journal/v2/n9/full/nrg0901_723a_fs.html

There isn't a lot of back up examples for the basic purpose of these filaments. For example, the microfilaments section could use a organized (bulleted) section of examples of what microfilaments aid in and their sole purpose in enabling cells to grow. I found some simple explanations from Armst1865 (talk) 23:51, 9 October 2017 (UTC)

Peer Review

While this article provides a solid basis of understanding for the cytoskeleton, there are several areas in need of improvement:

The introductory section is well-developed and easy to read for the lay person, but may benefit from being condensed. In the first paragraph, the cytoskeleton of eukaryotes is described as being "composed of three main proteins..."; I believe this should read protein filaments, as there are several different proteins that make up intermediate filaments (as stated correctly in the corresponding subsection). Including some key functions of the cytoskeleton in the introductory section is essential for initial understanding of the topic; however, not as much detailed information needs to be included. Definitions of linked key terms should be removed in order to improve brevity, as readers may click on the link to further understand the term if they are unfamiliar. Functions of the cytoskeleton are of huge importance and would make a great new section. Also, the example of muscle contraction needs citation(s) and clarification that it is in reference to eukaryotic cytoskeletal elements.

The history section needs expansion. Also, there is some close paraphrasing from the Nikolai K. Koltsov that may need to be reworded.

The microfilament subsection is too technical, and needs a broader explanation. The linked microfilament page should supply some excellent sources for this.

The intermediate filaments and microtubule subsections are in better shape than that of microfilament, but could also use some expansion and improved citations from their corresponding main articles.

I suggest moving septins, spectrin, and yeast cytoskeleton subsections into a new section in order to prevent confusion with the three main types of eukaryotic filaments, as well as to maintain symmetry with the prokaryotic section.

The prokaryotic section needs development to match the depth of the eukaryotic section.

There are some grammatical errors and simple formatting that would also greatly improve this article. A TEM micrograph showing internal filament structure seems pertinent to this article as well. --Austalexina (talk) 00:19, 1 October 2016 (UTC)

Prokaryote Introduction

My group would like to add the date when comparisons between eukaryotic and prokaryotic cytoskeletons were drawn (1992). In 1992 and 1993, three separate groups (de Boer et al., Raychaudhuri and Park, and Mukherjee et al.) purified FtsZ from Escherichia coli and found that it hydrolyzed GTP. It is surprising how recently these groundbreaking discoveries were made. S holley3393 (talk) 16:04, 6 October 2017 (UTC)

Microtubules

The microtubules’ section mentions in the second paragraph of a “9+2” arrangement that the tubules form. A picture from Wikimedia could be a simple fix for clarity of said arrangement. Wikimedia provides a simplified enough picture to clarify what they mean by the '9+2' arrangement. Armst1865 (talk) 23:53, 9 October 2017 (UTC)

Cytoplasmic Streaming

My group and I would like to add an entire section and subheading called Cytoplasmic streaming to explain how it relates to the cytoskeleton. The separate article for cytoplasmic streaming is highly specific to certain experiments. Therefore, we want to add a concise section to this article. We would like to add background information on cytoplasmic streaming to explain what it is. Then, possible history will added, according to the discovery dates and timeline as it relates to cytoskeleton discoveries. Next, we want to add where this is happening and in what type of cells. Lastly, we would like to explain how this process works and why it works for the cell.

Eukaryotic Cytoskeleton

Our group decided to expand on the information of Actin Filaments and Intermediate Filaments as well as how these filaments play a role in muscle contractions. Muscle contractions are touched on very lightly but providing more information would give better insight in how these filaments work together in the cell, with other cells, and conjunction with proteins. Both sections on Actin and Intermediate filaments could use more information to differentiate themselves from the other filaments listed in the article. William McNeel (talk) 01:24, 13 October 2017 (UTC)

History

Our section will focus on the history of the cytoplasm. The specific points will be who discovered it, when, where and a little on the path to identify and discover the cytoplasm.

The discussion of Hameroff / Penrose's theory of microtubules is highly controversial and there are many credible sources showing that the phenomena they discuss could not occur at body temperature. It is not only dismissive but patently untrue (as evidenced by decades of research) that the cytoskeleton would be considered "uninteresting" without their theory of consciousness. — Preceding unsigned comment added by 134.174.21.188 (talk) 16:57, 23 September 2018 (UTC)

Lead (heading) much too long?

This article looks very well done, and I'm just a passerby, so this is just my opinion, but it seems to me that the lead (heading) is much too long; it should, if I understand wiki article formation correctly, just summarize the article. Details that are currently in the lead should perhaps rather be in the actual sections of the article. And it should/could maybe start more like: "The cytoskeleton is an organized network of three types of protein filaments: microtubules, actin filaments, and intermediate fibers, and provides the cell with structure, shape, compartmentalization, and movement of macromolecules." From: Plant Virology (Fifth Edition), 2014, via ScienceDirect, Cytoskeleton. (I would change the 'and provides' in the above quote to 'which provides') (And the references below do not belong to my comment, they just seem to be permanently at the bottom of this talk page?)

Heading - muscle contraction volume of info

The heading section seems to focus too deeply on the mechanism behind muscle contraction given that it is an article about the cytoskeleton in general. 82.16.58.104 (talk) 21:30, 9 February 2024 (UTC)
