Steroid Receptors
The article on heat shock proteins references this page and labels HSP90 as "Maintenance of steroid receptors and transcription factors." I'm really ignorant about this and was hoping to find this mentioned on this page. Can anybody help?doctorwolfie (talk) 11:34, 29 January 2008 (UTC)


 * I have added a new section to this article which briefly discusses the role of Hsp90 in normal cells and uses the glucocorticoid receptor (which is a type of steroid receptor) as an example. In short, Hsp90 is crucial in maintaining steroid receptors in a conformation that is capable of binding hormone and also assists in transporting the receptor from the cytoplasm into the nucleus.  I hope this helps.  Boghog2 (talk) 06:13, 30 June 2008 (UTC)

Ganetespib
On June 4, 2011, at the Annual Meeting of the American Society for Clinical Oncology (ASCO) a paper was presented on HSP-90 inhibitor ganetespib phase 2 non-small cell lung cancer trial results showing encouraging single agent clinical activity without eye or liver side effects. It is my understanding that ganetespib may be the only current HSP-90 inhibitor that is now showing broad spectrum efficacy with minimal side effects. If so, this remarkable development bears watching and perhaps will merit incorporation in the article. Frankatca (talk)frankatca —Preceding undated comment added 01:07, 5 June 2011 (UTC).

 * If there is not a free use image in the top right corner of the article, please try to find and include one.[?]
 * There may be an applicable infobox for this article. For example, see Template:Infobox Biography, Template:Infobox School, or Template:Infobox City.[?] (Note that there might not be an applicable infobox; remember that these suggestions are not generated manually)
 * Per Wikipedia:Context and Build the web, years with full dates should be linked; for example, link January 15, 2006.[?]
 * Per Manual of Style (headings), headings generally should not repeat the title of the article. For example, if the article was Ferdinand Magellan, instead of using the heading  ==Magellan's journey== , use  ==Journey== .[?]
 * There are a few occurrences of weasel words in this article- please observe WP:AWT. Certain phrases should specify exactly who supports, considers, believes, etc., such a view.

 * might be weasel words, and should be provided with proper citations (if they already do, or are not weasel terms, please strike this comment).[?]
 * Please make the spelling of English words consistent with either American or British spelling, depending upon the subject of the article. Examples include: recognize (A) (British: recognise), realize (A) (British: realise), ization (A) (British: isation), isation (B) (American: ization), signaling (A) (British: signalling), any more (B) (American: anymore).
 * Watch for redundancies that make the article too wordy instead of being crisp and concise. (You may wish to try Tony1's redundancy exercises.)
 * Vague terms of size often are unnecessary and redundant - “some”, “a variety/number/majority of”, “several”, “a few”, “many”, “any”, and “all”. For example, “ All pigs are pink, so we thought of a number of ways to turn them green.”
 * As done in WP:FOOTNOTE, footnotes usually are located right after a punctuation mark (as recommended by the CMS, but not mandatory), such that there is no space in between. For example, the sun is larger than the moon [2]. is usually written as the sun is larger than the moon.[2][?]

HSP90 Inhibitor Trial
I'm starting an oral HSP90 inhibitor trial next week at MD Anderson made by Infinity Pharmaceuticals called IPI-493. I am JAK2 positive and being treated for myelofibrosis. The JAK2 inhibitors worked for one year for me then quit. If you're interested in progress, please feel free to drop me a line. --Saalanc (talk) 04:39, 12 June 2010 (UTC)

On a slightly related note. I added a link to a future HSP 90 inhibitor page that I hope with the help of a few students have up in a few days. Jasoninkid (talk) 16:30, 9 May 2011 (UTC)

Tumor repression?
The lead section claims that Hsp90 assists in tumor repression. Reading through the later sections, it appears to me that the opposite is true: it assists in the maintenance of tumors, by stabilizing mutant proteins, growth factor receptors, and signal transduction proteins. This explains why Hsp90 inhibitors are investigated as potential cancer medications--why would you want to inhibit a tumor repressor? AxelBoldt (talk) 23:43, 18 February 2012 (UTC)


 * OK, I removed "tumor repression" and instead mentioned its involvement in tumor growth and Hsp90 inhibitors in the intro. AxelBoldt (talk) 00:13, 25 February 2012 (UTC)

Role in evolution
I read Ed Yong's National Geographic article "How A Fish Unleashed Its Evolutionary Potential And Went Blind" and thought I should mention it here.

The suggestion is that Hsp90 plays a very important role in evolution by allowing genetic variation to accumulate without any phenotypic impact. A large amount of variation can then be trialled in offspring during long periods of stress, such as when the environment has permanently changed.

Hsp90 in Amyotrophic Lateral Sclerosis
Heat shock proteins frequently show up in the research literature on ALS and I wanted to just put in a mention but I could not figure out how to do that.

According to Miyazaki et. al. HSP90 (and HSP70) is higher in ALS than controls and remains high through the course of the disease. "The biological source of serum HSPs and the mechanisms mediating the increased expression of serum HSPs in patients with ALS remain unclear." dawot (talk) 13:02, 3 March 2019 (UTC)
