    Genome integrity, stem cells and hyaluronan

    Abstract

    Faithful preservation of genome integrity is the critical mission of stem cells as well as of germ cells. Reviewed are the following mechanisms involved in protecting DNA in these cells: (a) The efflux machinery that can pump out variety of genotoxins in ATP-dependent manner; (b) the mechanisms maintaining minimal metabolic activity which reduces generation of reactive oxidants, by-products of aerobic respiration; (c) the role of hypoxic niche of stem cells providing a gradient of variable oxygen tension; (d) (e) the presence of hyaluronan (HA) and HA receptors on stem cells and in the niche; (f) the role of HA in protecting DNA from oxidative damage; (g) the specific function of HA in protecting DNA in stem cells; (h) the interactions of HA with sperm cells and oocytes that also may shield their DNA from oxidative damage, and (e) mechanisms by which HA exerts the anti-oxidant activity. While HA has multitude of functions its anti-oxidant capabilities are often overlooked but may be of significance in preservation of integrity of stem and germ cells genome.https://www.aging-us.com/article/100438


    When public discuss modern medicine, precision plays one of the most crucial roles and people’s lives are directly dependent on it. Hereby, any researches pertaining to medicine are necessary to comply with the top standards. The problem today is that any results of researches can be posted online and used as a reference without being thoroughly verified and validated. Mikhail (Misha) Blagosklonny of Oncotarget clearly understood this problem and tried to develop an alternative solution. That’s how a weekly oncology-focused research journal called “Oncotarget” has been established back in 2010. The key principle of this journal is based on Altmetric scores that are used as a quality measure. That helps both readers and authors to validate publications with Altmetric Article Reports that create “real-time feedback containing data summary related to a particular publication.” Oncotarget website has a complete publications list with corresponding scores higher than 100 as well as reports mentioned previously. Mikhail (Misha) Blagosklonny glad to share his new approach and hopes it creates the necessary assistance to anyone, who has interest in oncology.
    “A diagnostic autoantibody signature for primary cutaneous melanoma” has the Altmetric score of 594. This paper was published back in 2018 by Oncotarget and completed by several experts from Hollywood Private Hospital, Edith Cowan University, Dermatology Specialist Group, St. John of God Hospital and The University of Western Australia. The introduction of the study mentions that “recent data shows that Australians are four times more likely to develop a cancer of the skin than any other type of cancer”, and shares an insight on melanoma that “is curable by surgical excision in the majority of cases, if detected at an early stage.”
    The article has got an Altmetric score of 594. Mikhail (Misha) Blagosklonny realizes that majority of readers are willing to understand the very meaning of it. Based on the Altmetric website, the score relates to “how many people have been exposed to and engaged with a scholarly output.” Hence, the paper about melanoma, was utilized for citations in various news articles 69 times. Moreover, it was mentioned in 2 online blogs, as well as 25 Tweets on Twitter and 1 Facebook post. FOX23 of Tulsa, Oklahoma has headlined their report on July 20, 2018 as “New blood test could detect skin cancer early”, using the main content of Australia study 
    Another Oncotarget’s research with a top score of 476, is “Biomarkers for early diagnosis of malignant mesothelioma: Do we need another moon-shot,”. This research has appeared in 60 news stories, 1 online blog post and 6 Twitter posts. The majority of public may have come across a short overview only, however those who visit Mikhail (Misha) Blagosklonny at Oncotarget, do receive helpful scientific facts. Oncotarget is proud to have the ability to share with online readers this highly appreciated and high-quality information, that is trustworthy and reliable.
