At concentrations that inhibit mTOR, resveratrol suppresses cellular senescence
Abstract
Here we demonstrated that, at cytostatic, near-toxic concentrations, resveratrol inhibited S6 phosphorylation and prevented the senescence morphology in human cells. Using a sensitive functional assay, we found that resveratrol partially prevented loss of the proliferative potential associated with cellular senescence. Resveratrol was less effective than rapamycin, because aging-suppression by resveratrol was limited by its toxicity at high concentrations. We discuss whether concentrations of resveratrol that inhibit mTOR (target of rapamycin) and suppress cellular senescence are clinically achievable and whether partial inhibition of mTOR by resveratrol might be sufficient to affect organismal aging. https://www.researchgate.net/scientific-contributions/39445053_Zoya_N_Demidenko
oncotarget research Zoya Demidenko Dr. Zoya N. Demidenko Zoya N. Demidenko , Ph.D. is Executive Manager of the Oncotarget journal . Oncotarget publishes high-impact research papers of general interest and outstanding significance and novelty in all areas of biology and medicine: in translational, basic and clinical research including but not limited to cancer research, oncogenes, oncoproteins and tumor suppressors, signaling pathways as potential targets for therapeutic intervention, shared targets in different diseases (cancer, benign tumors, atherosclerosis, eukaryotic infections, metabolic syndrome and other age-related diseases), chemotherapy, and new therapeutic strategies. After earning her Ph.D. in molecular biology, Zoya was awarded a Fogarty post-doctoral Fellowship from the National Institutes of Health in Bethesda, MD. After successful completion of post-doctoral training, she continued her professional career at George Washington University and Albert Einstein School of Medicine . In 2005 she cofounded the startup company Oncotarget Inc. which is focused on the development of anti-aging and anti-cancer drugs. Her research interests include signal transduction, cell cycle and cellular senescence, and their pharmacological targeting. In 2009 she cofounded the publishing house Impact Journals which specializes in publishing scientific journals. In 2011 she was selected to be a Member of the National Association of Professional Women .
When general population mention modern medicine, precision plays one of the most significant roles and human lives are directly dependent on it. Hereby, any researches pertaining to medicine are necessary to comply with the top standards. The issue nowadays is that any results of researches can be posted online and used as a reference without being precisely verified and validated. Mikhail (Misha) Blagosklonny of Oncotarget perfectly understood this challenge and decided to create an alternative solution. That’s how a weekly oncology-focused research journal called “Oncotarget” has been established back in 2010. The major principle of this journal is related to Altmetric scores that are used as a quality indicator. That assists 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 higher than 100 as well as reports discussed 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 study 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 discusses “recent data shows that Australians are four times more likely to develop a cancer of the skin than any other type of cancer”, and provides 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 comprehend 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.” Likewise, the paper about melanoma, was utilized for citations in various news articles 69 times. In addition, it was quoted 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 research has appeared in 60 news stories, 1 online blog post and 6 Twitter posts. The majority of public may have come across a concise overview only, however those who visit Mikhail (Misha) Blagosklonny at Oncotarget, do get useful scientific facts. Oncotarget is proud to have the ability to share with online viewers this highly appreciated and high-quality information, that is trustworthy and reliable.
