    Folate Receptor Alpha Expression in Lung Cancer: Diagnostic and Prognostic Significance




    ABSTRACT

    With the advent of targeted therapies directed towards folate receptor alpha, with several such agents in late stage clinical development, the sensitive and robust detection of folate receptor alpha in tissues is of importance relative to patient selection and perhaps prognosis and prediction of response. The goal of the present study was to evaluate the expression of folate receptor alpha in non-small cell lung cancer specimens to determine its frequency of expression and its potential for prognosis. The distribution of folate receptor alpha expression in normal tissues as well as its expression and relationship to non-small cell lung cancer subtypes was assessed by immunohistochemistry using tissue microarrays and fine needle aspirates and an optimized manual staining method using the recently developed monoclonal antibody 26B3. The association between folate receptor alpha expression and clinical outcome was also evaluated on a tissue microarray created from formalin fixed paraffin embedded specimens from patients with surgically resected lung adenocarcinoma. Folate receptor alpha expression was shown to have a high discriminatory capacity for lung adenocarcinomas versus squamous cell carcinomas. While 74% of adenocarcinomas were positive for folate receptor alpha expression, our results found that only 13% of squamous cell carcinomas were FRA positive (p<0.0001). In patients with adenocarcinoma that underwent surgical resection, increased folate receptor alpha expression was associated with improved overall survival (Hazard Ratio 0.39, 95% CI 0.18-0.85). These data demonstrate the diagnostic relevance of folate receptor alpha expression in non-small cell lung cancer as determined by immunohistochemistry and suggest that determination of folate receptor alpha expression provides prognostic information in patients with lung adenocarcinoma. https://www.oncotarget.com/article/519/



    When people refer to today’s medicine, precision plays one of the most significant roles and people’s lives are literally dependent on it. Hence, any researches pertaining to medicine are required to meet the top standards. The challenge today is that any recommendations 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 come up with an alternative solution. That’s how a weekly oncology-focused research journal named “Oncotarget” has been established back in 2010. The main principle of this journal is related to Altmetric scores that are used as a quality measure. 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 corresponding scores above 100 as well as reports discussed previously. Mikhail (Misha) Blagosklonny glad to share his new approach and hopes it provides the required help to anybody, 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 written by various 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 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 paper 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 research with a top score of 476, is “Biomarkers for early diagnosis of malignant mesothelioma: Do we need another moon-shot,”. This article 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 receive helpful scientific facts. Oncotarget is glad to have the ability to share with online readers this highly appreciated and high-quality information, that is trustworthy and reliable.

    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.

    Drug-Targeted Inhibition of Peroxisome Proliferator-Activated Receptor-gamma Enhances the Chemopreventive Effect of Anti-Estrogen Therapy

     

     
     

    ABSTRACT

    The peroxisome proliferator-activated receptorγ (PPARγ) is a key regulator of metabolism, proliferation, inflammation and differentiation, and upregulates tumor suppressor genes, such as PTEN, BRCA1 and PPARγ itself. Examination of mammary carcinogenesis in transgenic mice expressing the dominant-negative Pax8PPARγ fusion protein revealed that tumors were estrogen receptorα (ER)-positive and sensitive to the ER antagonist, fulvestrant. Here we evaluated whether administration of an irreversible PPARγ inhibitor in vivo could similarly induce ER expression in otherwise ER-negative mammary tumors following induction of carcinogenesis, and sensitize them to the antitumor effects of fulvestrant. In addition, we wished to determine whether the effect of GW9662 was associated with a PPAR-selective gene expression profile. Mammary carcinogenesis was induced in wild-type FVB mice by treatment with medroxyprogesterone and dimethylbenz(a)anthracene (DMBA) that were subsequently maintained on a diet supplemented with 0.1% GW9662, and tumorigenesis and gene expression profiling of the resulting tumors were determined. Administration of GW9962 resulted in ER+ tumors that were highly sensitive to fulvestrant. Tumors from GW9662-treated animals exhibited reduced expression of a metabolic gene profile indicative of PPARγ inhibition, including PPARγ itself. Additionally, GW9662 upregulated the expression of several genes associated with the transcription, processing, splicing and translation of RNA. This study is the first to show that an irreversible PPARγ inhibitor can mimic a dominant-negative PPARγ transgene to elicit the development of ER-responsive tumors. These findings suggest that it may be possible to pharmacologically influence the responsiveness of tumors to anti-estrogen therapy. https://www.oncotarget.com/article/457/

    Single Enantiomer of YK-4-279 Demonstrates Specificity in Targeting the Oncogene EWS-FLI1

    on June 10, 2020
     

    Single Enantiomer of YK-4-279 Demonstrates Specificity in Targeting the Oncogene EWS-FLI1




    ABSTRACT

    Oncogenic fusion proteins, such as EWS-FLI1, are excellent therapeutic targets as they are only located within the tumor. However, there are currently no agents targeted toward transcription factors, which are often considered to be ‘undruggable.’  A considerable body of evidence is accruing that refutes this claim based upon the intrinsic disorder of transcription factors.  Our previous studies show that RNA Helicase A (RHA) enhances the oncogenesis of EWS-FLI1, a putative intrinsically disordered protein.  Interruption of this protein-protein complex by small molecule inhibitors validates this interaction as a unique therapeutic target.  Single enantiomer activity from a chiral compound has been recognized as strong evidence for specificity in a small molecule-protein interaction.  Our compound, YK-4-279, has a chiral center and can be separated into two enantiomers by chiral HPLC.  We show that there is a significant difference in activity between the two enantiomers.  (S)-YK-4-279 is able to disrupt binding between EWS-FLI1 and RHA in an immunoprecipitation assay and blocks the transcriptional activity of EWS-FLI1, while (R)-YK-4-279 cannot.  Enantiospecific effects are also established in cytotoxicity assays and caspase assays, where up to a log-fold difference is seen between (S)-YK-4-279 and the racemic YK-4-279.  Our findings indicate that only one enantiomer of our small molecule is able to specifically target a protein-protein interaction. This work is significant for its identification of a single enantiomer effect upon a protein interaction suggesting that small molecule targeting of intrinsically disordered proteins can be specific. Furthermore, proving YK-4-279 has only one functional enantiomer will be helpful in moving this compound towards clinical trials. https://www.oncotarget.com/article/454/

    Recent Developments in Targeting Carbonic Anhydrase IX for Cancer Therapeutics

    on June 10, 2020
     

    Recent Developments in Targeting Carbonic Anhydrase IX for Cancer Therapeutics




    ABSTRACT

    Carbonic anhydrase IX (CAIX) is a hypoxia-inducible enzyme that is overexpressed by cancer cells from many tumor types, and is a component of the pH regulatory system invoked by these cells to combat the deleterious effects of a high rate of glycolytic metabolism.  CAIX functions to help produce and maintain an intracellular pH (pHi) favorable for tumor cell growth and survival, while at the same time participating in the generation of an increasingly acidic extracellular space, facilitating tumor cell invasiveness.  Pharmacologic interference of CAIX catalytic activity using monoclonal antibodies or CAIX-specific small molecule inhibitors, consequently disrupting pH regulation by cancer cells, has been shown recently to impair primary tumor growth and metastasis.  Many of these agents are in preclinical or clinical development and constitute a novel, targeted strategy of cancer therapy. https://www.oncotarget.com/article/422/

    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.

    Geminin overexpression induces mammary tumors via suppressing cytokinesis.

    Geminin overexpression induces mammary tumors via suppressing cytokinesis.

    ABSTRACT

    Aneuploidy plays an important role in the development of cancer. Here, we uncovered an oncogenic role for geminin in mitotic cells. In addition to chromatin, tyrosine phosphorylated geminin also localizes to centrosome, spindle, cleavage furrow and midbody during mitosis. Geminin binding to Aurora B prevents its binding to INCENP, and thus activation leading to lack of histone H3-(serine 10) phosphorylation, chromosome condensation failure, aborted cytokinesis and the formation of aneuploid, drug resistance cells. Geminin overexpressing human mammary epithelial cells form aneuploid, aggressive tumors in SCID mice. Geminin is overexpressed in more than half of all breast cancers analyzed. The current study reveals that geminin is a genuine oncogene that promotes cytokinesis failure and production of aneuploid, aggressive breast tumors when overexpressed and thus a worthy therapeutic target (oncotarget) for aggressive breast cancer. https://www.oncotarget.com/article/363/

    When people speak of modern medicine, precision plays one of the most crucial roles and human lives are directly dependent on it. Hence, any researches related to medicine are necessary to meet the top standards. The issue today is that any conclusions of researches can be shared online and used as a reference without being thoroughly checked and approved. Mikhail (Misha) Blagosklonny of Oncotarget perfectly understood this issue and attempted to generate 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 based on Altmetric scores that are used as a quality measure. That allows 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 provides a complete publications list with respective scores above 100 as well as reports discussed previously. Mikhail (Misha) Blagosklonny glad 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 paper was published back in 2018 by Oncotarget and written 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 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.” Hereby, the paper about melanoma, was utilized for citations in different news articles 69 times. Moreover, 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
