The connection between lymphangiogenic signalling and prostaglandin biology: A missing link in the metastatic pathway




ABSTRACT

Substantial evidence supports important independent roles for lymphangiogenic growth factor signaling and prostaglandins in the metastatic spread of cancer. The significance of the lymphangiogenic growth factors, vascular endothelial growth factor (VEGF)-C and VEGF-D, is well established in animal models of metastasis, and a strong correlation exits between an increase in expression of VEGF-C and VEGF-D, and metastatic spread in various solid human cancers. Similarly, key enzymes that control the production of prostaglandins, cyclooxygenases (COX-1 and COX-2, prototypic targets of Non-steroidal anti-inflammatory drugs (NSAIDs)), are frequently over-expressed or de-regulated in the progression of cancer. Recent data have suggested an intersection of lymphangiogenic growth factor signaling and the prostaglandin pathways in the control of metastatic spread via the lymphatic vasculature. Furthermore, this correlates with current clinical data showing that some NSAIDs enhance the survival of cancer patients through reducing metastasis. Here, we discuss the potential biochemical and cellular basis for such anti-cancer effects of NSAIDs through the prostaglandin and VEGF signaling pathways.https://www.oncotarget.com/article/593/

When general population speak of today’s medicine, precision plays one of the most significant roles and human lives are literally dependent on it. Hereby, any researches related to medicine are required to meet 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 attempted to generate an alternative solution. That’s how a weekly oncology-focused research journal named “Oncotarget” has been founded back in 2010. The major principle of this journal is based on Altmetric scores that are used as a quality measure. That assists both readers and authors to verify publications with Altmetric Article Reports that provide “real-time feedback containing data summary related to a particular publication.” Oncotarget website has a full publications list with corresponding scores above 100 as well as reports discussed previously. Mikhail (Misha) Blagosklonny proud to share his new approach and hopes it provides the required assistance to anybody, 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 written 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 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 article has got an Altmetric score of 594. Mikhail (Misha) Blagosklonny realizes that most of readers are willing 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.” Likewise, the publication about melanoma, was utilized for citations in different news articles 69 times. Besides that, it was referred to 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 seen a short overview only, however those who visit Mikhail (Misha) Blagosklonny at Oncotarget, do get useful scientific facts. Oncotarget is glad to have the chance to share with online customers this highly appreciated and top-quality information, that is trustworthy and reliable.

impact journals llc 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 .

Mikhail (Misha) V. Blagosklonny graduated with an MD and PhD from First Pavlov State Medical University of St. Petersburg, Russia. Dr. Mikhail V. Blagosklonny has then immigrated to the United States, where he received the prestigious Fogarty Fellowship from the National Institutes of Health. During his fellowship in Leonard Neckers’ lab at the National Cancer Institute (NCI), he was a co-author of 18 publications on various biomedical themes, including targeting HSP90, p53, Bcl2, Erb2, and Raf-1. He also was the last author for a clinical phase I/II trial article. 
After authoring seven papers during a brief yet productive senior research fellowship in the El-Deiry Cancer Research Lab at the University of Pennsylvania, Dr. Blagosklonny returned to NCI to work with Tito Fojo. Together, they published 26 papers. Moreover, Dr. Blagosklonny published many of experimental research papers and theoretical papers as sole author. The abovementioned sole-author articles discussed two crucial topics. The first of these discussed selectively killing cancer cells with deregulated cell cycle or drug resistance via verifying their resistance. The outcomes and underlying notion were so revolutionary that they were incorrectly cited by other scientists as “reversal of resistance,” even though the publication was titled, “Exploiting of drug resistance instead of its reversal.” One big supporter of this concept was the world-famous scientist Arthur Pardee, with whom Dr. Blagosklonny co-authored a joint publication in 2001.
The second theme throughout Dr. Blagosklonny’s sole-author articles is a research method to develop knowledge by bringing several facts together from seemingly irrelevant areas. This results in new notions with testable forecasts, which in turn can be “tested” via analyzing the literature further. Likewise, the concept was co-authored by Arthur Pardee in a 2002 article in Nature. The first success of the new research methodology was the description of the feedback regulation of p53, as confirmed by the discovery of mdm2/p53 loop; and the explanation why mutant p53 is always overexpressed, published in 1997. The most important result revealed by Dr. Blagosklonny’s research methodology is the hyperfunction (or quasi-programmed) theory of aging and the revelation of rapamycin as an exclusively well-tolerated anti-aging drug, published in 2006. As mentioned in Scientific American, Michael Hall, who discovered mTOR in 1991, gives Dr. Blagosklonny credit for “connecting dots that others can’t even see.”
In 2002, Dr. Blagosklonny became associate professor of medicine at New York Medical College. He agreed to accept responsibilities as a senior scientist at Ordway Research Institute in Albany, New York, in 2005, before receiving another position at Roswell Park Cancer Institute as professor of oncology in 2009.
Since coming to Roswell Park Comprehensive Cancer Center in 2009, Dr. Blagosklonny has studied the prevention of cancer (an age-related disease) via stopping organism aging - in other words, “preventing cancer via staying young.” His laboratory closely worked together with Andrei Gudkov’s and conducted research on the suppression of cellular senescence, namely suppression of cellular conversion from healthy quiescence to permanent senescence. This led to the discovery of additional anti-aging medicines beyond rapamycin. The cell culture studies were complemented by studies in mice, including several models like normal and aging mice, p53-deficient mice, and mice on a high-fat diet.
Dr. Blagosklonny has also published extensively on the stoppage of cellular senescence via rapamycin and other mTOR inhibitors, life extension and cancer stoppage in mice, and combinations of anti-aging medicines to be taken by humans. A rapamycin-based combination of seven clinically available medications has been named the “Koschei Formula” and is now used for the treatment of aging in patients at the Alan Green Clinic in Little Neck, New York.
