*Reggiani said that he does not know for sure if there is differences at the molecular level between "urinary system type smooth muscle contraction" and "artery type smooth muscle contraction" but He said that these type of muscle might have a difference expresion profiles, for instance they express different kind of receptors for hormons or different channels. Should I delete these muscle type contraction terms? I saw that there is already a term GO:0003056 contraction of vascular smooth muscle which has been added by cardio_mtg.DONE

*'''Webex/skype chat about plasticity: Erika Feltrin, Jennifer Deegan, Alex Diehl'''<br>
 +
 
 +
We all did some reading over the last few days and came back to discuss muscle plasticity again. Just before the call started Alex sent out a proposed structure shown below:
 +
 
 +
[i]muscle adaptation -- synonym (related):muscle plasticity
 +
--[i]muscle atrophy
 +
----[p]regulation of muscle atrophy
 +
------[i]negative regulation of muscle atrophy
 +
------[i]positive regulation of muscle atrophy
 +
--[i]muscle hypertrophy
 +
----[p]regulation of muscle hypertrophy
 +
------[i]negative regulation of muscle hypertrophy
 +
------[i]positive regulation of muscle hypertrophy
 +
--[p]regulation of muscle adaptation  ; related syn: regulation of muscle plasticity
 +
----[i]negative regulation of muscle adaptation  ; related syn: negative regulation of muscle plasticity
 +
------[i]negative regulation of muscle atrophy
 +
------[i]negative regulation of muscle hypertrophy
 +
----[i]positive regulation of muscle adaptation  ; related syn: positive regulation of muscle plasticity
 +
------[i]positive regulation of muscle atrophy
 +
------[i]positive regulation of muscle hypertrophy
 +
----[i]regulation of muscle atrophy
 +
------[i]negative regulation of muscle atrophy
 +
------[i]positive regulation of muscle atrophy
 +
----[i]regulation of muscle hypertrophy
 +
------[i]negative regulation of muscle hypertrophy
 +
------[i]positive regulation of muscle hypertrophy
 +
--[i]muscle hyperplasia
 +
----[p]regulation of muscle hyperplasia
 +
------[i]negative regulation of muscle hyperplasia
 +
------[i]positive regulation of muscle hyperplasia
 +
 
 +
He suggests that as the ambiguous community use of the word plasticity is what causes all the problems we might relegate it to the synonym field and only use unambiguous phrases in the term names. He further proposes that since the terms that we actually want to capture are things like hyperplasia, atrophy and hypertrophy, which are processes that adapt muscle, we might be best just to have the top term muscle adaptation to cover such processes, and forget about the quality term altogether. This way we can finish the edits that we are doing now, and if anyone ever wants a term to cover the meaning of plasticity that we think might require a regulation of quality term then we can deal with that when the time comes.
 +
 
 +
Erika and I agreed entirely with this approach and so Erika is implementing it immediately. We had previously merged the terms muscle plasticity and regulation of muscle plasticity but we went back and reverted this change before Erika started to implement the new plan.

We redefined contraction, which sounds like a function term just because some very detailed information was given about individual steps in the process. The def is now much more processy and Erika is going to reapply the standard definition accross the board.

We checked the cardio terms to make sure none had been lost as some defs were missing. It seemed as though some small things had just been forgotten so we will redo them. (Add one term, redefine three.)

I will check the old versions to make sure there was not actually loss of the pulmonary term.

I checked our muscle terms that were going to be x via y and David suggests we should think about changing them to be involved in terms. I think this will make more sense and will make it easier to make is_a parents.

We discussed the plan to release the cardio and muscle work.

We will probably email at the end of the week and then work through and double check the terms while the people on the go list look at them. We will commit a fortnight later.

Latest revision as of 08:45, 16 April 2019

12th September, 2007

Participants: Erika Feltrin, Jennifer Deegan

We went through about two thirds of the list on the google spreadsheet and figured out what to do about each item.


13th September, 2007

Participants: Erika Feltrin, Jennifer Deegan

We went through the descendants of skeletal muscle regeneration and fixed the graph and definitions. We made the terms is_a complete as we went along.

We made a new term called cell-cell fusion as an is_a parent for the myoblast fusion term. Cell-cell fusion has been placed as a cellular process.

14th September, 2007

Participants: Erika Feltrin, Jennifer Deegan

We worked on:

  • descendents of contractile fiber part
  • descendents of sarcoplasmic reticulum terms
  • descendents of muscle regeneration terms
  • cell fusion

We have now checked all the definitions and graphs for all of these terms and they are correct apart for 2 or 3 small outstanding questions. The questions are listed on the google spreadsheet and Erika and I have identified experts who can help us with them.

18th September, 2007

Participants: Erika Feltrin, Jennifer Deegan

  • Terms with myotube, myoblast or myofibre in the name were given cell definitions and synonyms.
  • We moved myotube development under muscle fibre development.
  • Inserted def for satellite cell in all terms covering satellite cell.
  • Checked defs for muscle regeneration terms except for EF:0014815 (a term covering growth factor in muscle regeneration.)
  • Wrote to David to ask about a skype call to cover striated muscle grouping.

Erika in the afternoon

  • EF:0014815 has a definition
  • ADDED two new terms:
    regulation of satellite cell activation involved in skeletal muscle regeneration
    positive regualtion of satellite cell activation involved in skeletal muscle regeneration
    MOVED EF:0014815 as a is_a of positive regulation of satellite cell activation involved in skeletal muscle regeneration
  • MOVED myblast migration involved in skeletal muscle regeneration is_a child of myoblast migration
  • ADDED a new term: satellite cell activation is_a cell activation
  • MOVED satellite cell activation involved in skeletal muscle regeneration is_a child satellite cell activation

HOMEWORKS:

  • WHAT IS A MUSCLE CELL? Check the muscle cell development structure
  • We need definitions for:
    myoblast cell fate commitment in head
    myoblast cell fate commitment in trunk
    regulation of branchiomeric skeletal muscle development
    negative regulation of branchiomeric skeletal muscle development
    positive regulation of branchiomeric skeletal muscle development
    regulation of somitomeric trunk muscle development
    negative regulation of somitomeric trunk muscle development
    positive regulation of somitomeric trunk muscle development

19th September, 2007

Participants: Erika Feltrin and Carlo Reggiani

AM

prof. Reggiani came and helped for definition of muscle contraction terms. We have defined almost all "muscle contraction" terms (he will come on Friday to get the work finished).
We have made these changes:

  • added or changed definitions for: muscle contraction
    voluntary and involuntary skeletal muscle contraction
    smooth muscle contraction
    phasic and tonic smooth muscle contraction
    striated muscle contraction
    diaphragm contraction
    skeletal muscle contraction
    fast/twitch and slow/twitch skeletal muscle contraction
  • Added new terms:
    twitch skeletal muscle contraction
    oscillatory skeletal muscle contraction
  • changed definition for GO:0031446, 0031447, 0031448 from striated to fast-twitch

QUESTIONS:

  • Reggiani said that he does not know for sure if there is differences at the molecular level between "urinary system type smooth muscle contraction" and "artery type smooth muscle contraction" but He said that these type of muscle might have a difference expresion profiles, for instance they express different kind of receptors for hormons or different channels. Should I delete these muscle type contraction terms? I saw that there is already a term GO:0003056 contraction of vascular smooth muscle which has been added by cardio_mtg.DONE

PM

Participants: Erika Feltrin, Jennifer Deegan and DAVID HILL

  • We need to get rid of all terms with type inside the term name
  • We consider plasticity a quality
  • Muscle cell (see CL) is a MATURE muscle cell and instead myoblast, myotube are precursors.
  • oscillatory skeletal muscle contraction should be "striated" Ask Reggiani for this!
  • we can do cross references between CL and GO (asked to Chris Mungall)
  • striated muscle development. To be asked to muscle experts. We can take it if it is too complicate.

20th September, 2007

Participants: Erika Feltrin, Jennifer Deegan

  • Check almost all the relationships and definitions under muscle contraction and skeletal muscle development.
  • Create a new spreadsheet with the list of the terms that should be defined called terms_to_define
  • Erika will write to muscle experts asking for definition for atrophy, hyperatrophy and other plasticity terms
  • Inserted MA and CL dbxrefs in the muscle contraction terms

22st September, 2007

Participants: Erika Feltrin and Reggiani

  • Reggiani defined all terms under muscle contraction
  • We have copied peristalsis also under phasic smooth muscle contraction EF:0014821
  • Reggiani said that Elastic Filament should be deleted.
  • We have added new terms:
    EF:0014728 regulation of force of skeletal muscle contraction
    EF:0014729 regulation of shortening velocity of skeletal muscle contraction

24th September, 2007

Participants: Erika Feltrin, Jennifer Deegan

  • Made some changes at the "muscle plasticity" structure: moved terms under "regulation of muscle plasticity" and added definitions of atrophy , hypertrophy and hyperplasia form cancer web dictionary (TO BE CHECKED)
  • I have destroy "elastic filament" that was under contratile fiber part and also sarcomere since it is made by just the portein titin Definition was: Non-contractile elastic cytoskeletal filaments in the sarcomere.
  • Ehler's suggestions:
    costamere GO:0043034 inserted New definition
  • modified definition for T-tubule and copied it also under sarcolemma as part_of.
  • Deleted the synonym of "intercaleted disc" from GO:0005916 and create a new term: EF:0014704 intercalated disc using Elisabeth's definition. Moved GO:0005916, 0030057 and 0005921 as part_of children of EF:0014704.
  • New term: EF0014731 spectrin-associated cytoskeleton PMID:15970557 but this citoskeleton is membrane-bounded but now it is under non -membrane bounded???

2nd October, 2007

Partecipants: Erika Feltrin and Jennifer Deegan

We have discussed about muscle plasticity terms. Correct the definition of costamere and muscle plasticity. We need to ask about merging between muscle plasticity and regulation of muscle plasticity.

Muscle Plasticity

We have a plan for muscle plasticity. We have written to Alex Deihl to ask for his thoughts. This is the plan:

Plan

Erika has spoken to experts on the muscle plasticity question. They have told us that for muscle plasticity the line between quality and process is so blurred as to be meaningless. We wondered if we might make the following structures. The whole thing is paraphrased, as we don't have rigorously thought out definitions and are just giving an idea of how we might do it to get feedback. However the term names with a * are our actual intended term names. Here's our idea:

[i]regulation of a biological quality
---[i]regulation of the biological quality of muscle plasticity* 
      (Something like: The process by which the ability of muscle to change its structure and activity is increased or decreased.)
------[i]positive regulation of the biological quality of muscle plasticity 
         (A process that makes muscles more able to adapt their structure and activity.)
------[i]negative regulation of the biological quality of muscle plasticity 
         (A process that makes muscles less able to adapt their structure and activity.)

Then to accommodate the language problem we thought about adding:

[i]muscle plasticity process* 
    (The process by which the structure and activity of muscle is actually changed.) This could have helpful synonyms.
---[i]muscle atrophy
---[i]muscle hypertrophy

We hope this might accommodate the really subtle use of language in the community, but help keep the concepts clearly apart in a useful way in the GO.

Muscle Plasticity

  • Alex and I discussed the proposal above, first by e-mail and then on skype.

This was Alex's initial e-mail response:

"I am a strong supporter of reflecting the language of biologists in the formation and organization of GO terms, although in this case I think the biologists have abused the language a bit. While I can live with the approach you have outlined, I have to admit that I find "regulation of the biological quality of muscle plasticity" needlessly wordy, and indeed sounding rather jargony. I think it would be less confusing just to say "regulation of muscle plasticity," with the definition you provide, since the placement of the term in the ontology would indicate that that we are referring to muscle plasticity as a biological quality in this case. We could even add a comment or extend the definition to say specifically that we are referring to muscle plasticity as a biological quality for this term.

I do like the "muscle plasticity process" term. Will it be a part_of to the "regulation of [the biological quality of] muscle plasticity" term? "

  • On the skype call we discussed the names of terms and then graph placement.
  • Jen agreed with Alex's points in his first paragraph above.
  • We agreed that muscle plasticity process might be well placed as a child of muscle development but that we should check with David.
  • We tried to work out how the two terms 'muscle plasticity process' and 'regulation of [the quality of] muscle plasticity' might be related to one another. Alex thought perhaps this would be good:
[i]regulation of [the quality of] muscle plasticity
---[p]muscle plasticity process

Jen did not really agree but did not have a clear idea of how else to relate them.
We decided to read a review that Erika has recommended to try to get a better idea.

In proposing this relationship, Alex suggested looking at the relationships between various blood pressure terms as a guide, although without much success. Alex also pointed out the distinction that for a biological quality such as blood pressure, negative and positive regulation terms were possible, since blood pressure is a quality which can be quantified, whereas for a biological quality such as muscle plasticity, negative and positive regulation terms may not be appropriate, depending on how one interprets the term. Alex gave a weak analogy to the skin color of a chameleon as a biological quality, where one could imagine having a "regulation of skin color" term, but not have negative and positive regulation terms.

In the end of the discussion we had some good new avenues to explore and we are going to read on with an open mind and get back together on Friday or Monday to discuss further.

I HAVE FOUND SOME DEFINITIONS FOR MUSCLE PLASTICITY:

Muscle Plasticity:

the ability of striated muscle tissue to adapt to changes in activity or in working conditions is extremely high. In some ways it is comparable to the ability of the brain to learn. The interest in muscle adaptation is increasing in relation to the idea that physical fitness helps in the prevention of disease, may counteract the loss of physical performance and generally improves wellbeing. Plasticity is the word used since the late 1970’s to indicate collectively all the processes and mechanisms which form the background of muscle adaptation. http://www.springer.com/west/home/new+&+forthcoming+titles+(default)?SGWID=4-40356-22-173664756-0

Skeletal muscle is the single most abundant tissue in higher animals. Thus, in order to minimize the expenditure for maintenance and maximize functionality, skeletal muscle has an enormous capacity to adapt to various stimuli, e.g., motor nerve activation and contractile activity, nutrient supply, temperature and hypoxia [1]. Altered signaling pathways and changes in metabolic and contractile properties contribute to the phenotypic plasticity of skeletal muscle. http://www.researchportal.ch/unizh/p7970.htm

In this report,we will be dealing with the concept of muscle plasticity, which is the ability of a given muscle cell to alter either the quantity (amount) of protein or the type of protein (i.e., phenotype or isoform) comprising its different sub-cellular components in response to any stimulus that disrupts its normal homeostasis. For example, a given muscle fiber may respond to chronic increases in mechanical stress (physical activity) by increasing its crosssectional area such that all of the subcellular components remain in normal proportion to one another and the same specific protein pheno-types are maintained in normal expression. In this case, the muscle expands both its protein mass and mechanical strength without qualitatively changing any other inherent functional property such as endurance or contractile speed. On the other hand, a given fiber may respond o the same perturbation by both increasing its mass and altering the type of MHC isoform that it expresses in the myofilaments. In this situation, as the muscle becomes both larger and stronger because of the increase in contractile protein accumulation, its intrinsic contractile properties also become transformed due to the altered myosin phenotype that is expressed. Thus, the muscle’s plasticity potential may involve (1) a change in the amount of protein, (2)the type of protein isoform it expresses, and (3) a combination of the two. However, the derived functional consequences of such a transformation will depend on which component or components of the cell are altered in terms of the quantity and quality of protein expression. http://www.nmdinfo.net/Publications/Consensus%20Conf%202002%20Papers/Baldwin.pdf

  • Webex/skype chat about plasticity: Erika Feltrin, Jennifer Deegan, Alex Diehl

We all did some reading over the last few days and came back to discuss muscle plasticity again. Just before the call started Alex sent out a proposed structure shown below:

[i]muscle adaptation -- synonym (related):muscle plasticity
--[i]muscle atrophy
----[p]regulation of muscle atrophy
------[i]negative regulation of muscle atrophy
------[i]positive regulation of muscle atrophy
--[i]muscle hypertrophy
----[p]regulation of muscle hypertrophy
------[i]negative regulation of muscle hypertrophy
------[i]positive regulation of muscle hypertrophy
--[p]regulation of muscle adaptation  ; related syn: regulation of muscle plasticity
----[i]negative regulation of muscle adaptation  ; related syn: negative regulation of muscle plasticity
------[i]negative regulation of muscle atrophy
------[i]negative regulation of muscle hypertrophy
----[i]positive regulation of muscle adaptation  ; related syn: positive regulation of muscle plasticity
------[i]positive regulation of muscle atrophy
------[i]positive regulation of muscle hypertrophy
----[i]regulation of muscle atrophy
------[i]negative regulation of muscle atrophy
------[i]positive regulation of muscle atrophy
----[i]regulation of muscle hypertrophy
------[i]negative regulation of muscle hypertrophy
------[i]positive regulation of muscle hypertrophy 
--[i]muscle hyperplasia
----[p]regulation of muscle hyperplasia
------[i]negative regulation of muscle hyperplasia
------[i]positive regulation of muscle hyperplasia

He suggests that as the ambiguous community use of the word plasticity is what causes all the problems we might relegate it to the synonym field and only use unambiguous phrases in the term names. He further proposes that since the terms that we actually want to capture are things like hyperplasia, atrophy and hypertrophy, which are processes that adapt muscle, we might be best just to have the top term muscle adaptation to cover such processes, and forget about the quality term altogether. This way we can finish the edits that we are doing now, and if anyone ever wants a term to cover the meaning of plasticity that we think might require a regulation of quality term then we can deal with that when the time comes.

Erika and I agreed entirely with this approach and so Erika is implementing it immediately. We had previously merged the terms muscle plasticity and regulation of muscle plasticity but we went back and reverted this change before Erika started to implement the new plan.

9th October

  • Participants: Erika Feltrin, Jennifer Deegan

We looked through the remaining to do items and made sure they were all assigned.

We redefined contraction, which sounds like a function term just because some very detailed information was given about individual steps in the process. The def is now much more processy and Erika is going to reapply the standard definition accross the board.

We decided to destroy the terms to do with longer sustained or strenuous muscle contractions as they were too difficult to define for now.

We fixed the parentage of the 'response to stimulus' and 'detection of stimulus' terms and they are ready to be sent off to Alex Diehl to be checked.

10th October

am.

Participants: Erika Feltrin, Jennifer Clark

We worked on the structure to do with regulation of muscle contraction and made extensive rearrangements to ensure univocity in the names and definitions and to add is_a completeness.

pm Participants: David Hill, Jennifer Deegan.

We checked the cardio terms to make sure none had been lost as some defs were missing. It seemed as though some small things had just been forgotten so we will redo them. (Add one term, redefine three.)

I will check the old versions to make sure there was not actually loss of the pulmonary term.

I checked our muscle terms that were going to be x via y and David suggests we should think about changing them to be involved in terms. I think this will make more sense and will make it easier to make is_a parents.

We discussed the plan to release the cardio and muscle work. We will probably email at the end of the week and then work through and double check the terms while the people on the go list look at them. We will commit a fortnight later.


11st October
