Autoantibodies against oncogenic ERG protein in prostate cancer: potential use in diagnosis and prognosis in a panel with C-MYC, AMACR and HERV-K Gag
ABSTRACT
Overdiagnosis and overtreatment of prostate cancer (CaP) is attributable to widespread reliance on PSA screening in the US. This has prompted us and others to search for improved biomarkers for CaP, to facilitate early detection and disease stratification. In this regard, autoantibodies (AAbs) against tumor antigens could serve as potential candidates for diagnosis and prognosis of CaP. Towards this, our goals were: i) To investigate whether AAbs against ERG oncoprotein (overexpressed in 25-50% of Caucasian American and African American CaP) are present in the sera of CaP patients; ii) To evaluate an AAb panel to enhance CaP detection. The results using an enzyme-linked immunosorbent assay (ELISA) showed that anti-ERG AAbs are present in a significantly higher proportion in the sera of CaP patients compared to healthy controls (p = 0.0001). Furthermore, a panel of AAbs against ERG, AMACR and human endogenous retrovirus-K Gag successfully differentiated CaP patient sera from healthy controls (AUC = 0.791). These results demonstrate for the first time that anti-ERG AAbs are present in the sera of CaP patients. In addition, the data also suggest that AAbs against ERG together with AMACR and HERV-K Gag may be a useful panel of biomarkers for diagnosis and prognosis of CaP.
When public mention modern medicine, precision plays one of the most crucial roles and people’s lives are literally dependent on it. Likewise, any researches pertaining to medicine are necessary to comply with the highest standards. The issue today is that any results of researches can be posted online and used as a reference without being thoroughly checked and validated. Mikhail (Misha) Blagosklonny of Oncotarget clearly understood this issue and tried to develop an alternative solution. That’s how a weekly oncology-focused research journal called “Oncotarget” has been founded back in 2010. The key principle of this journal is based on Altmetric scores that are used as a quality indicator. That allows both readers and authors to validate publications with Altmetric Article Reports that generate “real-time feedback containing data summary related to a particular publication.” Oncotarget website provides a complete publications list with respective scores above 100 as well as reports discussed above. Mikhail (Misha) Blagosklonny proud to share his new approach and hopes it creates the necessary help to anyone, who has interest in oncology.
“A diagnostic autoantibody signature for primary cutaneous melanoma” has the Altmetric score of 594. This article was published back in 2018 by Oncotarget and completed by different 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 paper has got an Altmetric score of 594. Mikhail (Misha) Blagosklonny realizes that majority of readers are aiming to understand the very meaning of it. Based on the Altmetric website, the score indicates “how many people have been exposed to and engaged with a scholarly output.” Hence, the paper about melanoma, was used for citations in various news articles 69 times. In addition, 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 news on July 20, 2018 as “New blood test could detect skin cancer early”, using the main content of Australia study
Another Oncotarget’s study with a top score of 476, is “Biomarkers for early diagnosis of malignant mesothelioma: Do we need another moon-shot,”. This study 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 useful scientific facts. Oncotarget is happy to have the ability to share with online customers this highly appreciated and top-quality information, that is trustworthy and reliable.
