The Forkhead box, subclass O (FOXO) proteins are critical transcription factors, ubiquitously expressed in the human body. These proteins are characterized by a remarkable functional diversity, being involved in cell cycle arrest, apoptosis, oxidative detoxification, DNA damage repair, stem cell maintenance, cell differentiation, cell metabolism, angiogenesis, cardiac development, aging and others. In addition, FOXO have critical implications in both normal and cancer stem cell biology. New strategies to modulate FOXO expression and activity may now be developed since the discovery of novel FOXO regulators and non-coding RNAs (such as microRNAs) targeting FOXO transcription factors. This review focuses on physiological and pathological functions of FOXO proteins and on their action as fine regulators of cell fate and context-dependent cell decisions. A better understanding of the structure and critical functions of FOXO transcription factors and tumor suppressors may contribute to the development of novel therapies for cancer and other diseases.

News & Events Latest news from our journals.

  • 2021, January| 2021 AWARDS!

    2021 DISCOVERIES AWARDS! Discoveries will offer a $1000 award and at least five $400 awards in Jan 2022, for the most cited (2021 ISI Citations) and visible (Altmetric Score) articles published in 2018-2021.

  • 2020, November| Discoveries on Twitter!

    You can now follow the latest Discoveries news and updates on Twitter! (@DiscoveriesNews) 

  • 2020, August| For Authors!

    Due to a high volume of article submissions, our peer-review process takes more than usual. The pre-screening decision is released in 1-2 days, while the peer-review process lasts between 10 and 20 days.  

  • 2020, April | For Authors!

    WE DO NOT TOLERATE ANY MISCONDUCT! Please be aware that we are testing all received articles with specialized software for PLAGIARISM and WE WILL TAKE MEASURES if your article is already published or in consideration for publication by other journals! This may result in serious professional consequences for the authors. The latest striking case is the following article which is already published and was re-submitted here.  

  • 2020, April | For Authors!

    We are happy to let you know that all articles published in Discoveries are now on PubMedCentral (PMC). New accepted articles will be included in PMC and PubMed within 1-2 weeks after their publication.

  • 2020, January | For Authors!

    Starting in January 2020, Discoveries will also consider articles submitted by Discoveries' Editorial Board members. However, only a small number of such articles (maximum 4 articles/year) will be considered for publication after the peer-review process, and the authors who are also our editors will be clearly disclosed. 

  • 2019, September | Indexed by PMC

    Discoveries is now indexed by PubMedCentral and Pubmed. The agreement with US National Library of Medicine was signed on September 10, 2019. Our next step is ISI Web of Science indexing. NOTE: previously published articles will be included on PubMed in early 2020.

  • 2019, September | PubMed inclusion!

    We are happy to let you know that Discoveries successfuly passed the last step (Technical Review) required for PubMedCentral and PubMed inclusion!

  • 2019, June | PubMed inclusion News!

    We are happy to receive positive comments from PMC/NLM-NIH regarding Discoveries' last step (Technical Review) required for PubMedCentral and PubMed inclusion. We will let you know once whole indexing process is completed. 

  • 2018-2019 | For Authors!

    From now on and for at least 1 year, we will only accept articles from authors that are NOT members of Discoveries' Editorial Board. All articles submitted by our editors will be immediately rejected until further notice. 

  • 2018 | PubMed inclusion News!

    Discoveries successfully passed the Scientific Quality Review by NLM-NIH for PubMedCentral and PubMed indexing. This is the first and the most important step towards PubMedCentral and PubMed indexing! The second (last) step is the Technical Review.

  • April 2016 | Faster Peer-Review

    Starting on April 13th, all articles selected for a peer-review will receive the post peer-review decision within 10 days. The initial pre-screening time will remain the same (48h from the submission of the manuscript). This decision will significantly accelerate the publication, with no effect on the quality of the peer-review process.

  • February 2016 | Manuscript submission

    Discoveries is commited to excellence, quality and high editorial standards. We are receiving an increasing number of manuscripts for which the identity of the authors/corresponding author can't be verified. Please NOTE that ALL these articles were and will be immediately REJECTED. Indicating an institutional email address is the easiest way to overcome this problem! Moreover, we do not accept any pressure on our editorial board to accept a manuscript. This results in a prompt rejection of the article.

    Editorial Policies
  • January 2016 |Discoveries-AIM

    After reaching all proposed milestones until now (including being indexed by Google Scholar in 2014), Discoveries' next Aim is PubMed indexing of all its articles (already published and upcoming). There will be no charge for the submission or publication of articles in Discoveries before PubMed indexing.

  • August 2015 | Discoveries - on PubMed

    We are happy to announce that our first Discoveries articles were included in PMC and PubMed. More articles (submitted by NIH funded articles) are now processed for being included.
