Multiple myeloma cell lines and primary tumors proteome: protein biosynthesis and Immune system as potential therapeutic targets

Multiple myeloma cell lines and primary tumors proteome: protein biosynthesis and Immune system as potential therapeutic targets

Issue 11-12, November 2015

ABSTRACT

Despite great advance in multiple myeloma (MM) treatment since 2000s, it is still an incurable disease and novel therapies are welcome. Therefore, the purpose of this study was to explore MM plasma cells’ (MM-PC) proteome, in comparison with their normal counterparts (derived from palatine tonsils of normal donors, ND-PC), in order to find potential therapeutic targets expressed on the surface of these cells. We also aimed to evaluate the proteome of MM cell lines with different genetic alterations, to confirm findings obtained with primary tumor cells. Bone marrow (BM) samples from eight new cases of MM and palatine tonsils from seven unmatched controls were submitted to PC separation and, in addition to two MM cell lines (U266, RPMI-8226), were submitted to protein extraction for mass spectrometry analyses. A total of 81 proteins were differentially expressed between MM-PC and ND-PC - 72 upregulated and nine downregulated; U266 vs. RPMI 8226 cell lines presented 61 differentially expressed proteins - 51 upregulated and 10 downregulated. On primary tumors, bioinformatics analyses highlighted upregulation of protein biosynthesis machinery, as well as downregulation of immune response components, such as MHC class I and II, and complement receptors. We also provided comprehensive information about U266 and RPMI-8226 cell lines’ proteome and could confirm some patients’ findings.http://www.impactjournals.com/Genes&Cancer/index.php?abs=88


When public mention modern medicine, precision plays one of the most significant roles and people’s lives are directly dependent on it. Hence, any researches related to medicine are required to meet the top standards. The problem nowadays is that any outcomes of researches can be posted online and used as a reference without being properly checked and approved. Mikhail (Misha) Blagosklonny of Oncotarget clearly understood this issue and tried to generate an alternative solution. That’s how a weekly oncology-focused research journal called “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 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 demonstrates a full publications list with respective scores higher than 100 as well as reports mentioned above. Mikhail (Misha) Blagosklonny proud to share his new approach and hopes it creates 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 paper 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 different 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 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 seen a brief overview only, however those who visit Mikhail (Misha) Blagosklonny at Oncotarget, do get helpful scientific facts. Oncotarget is glad to have the chance to share with online viewers this highly appreciated and top-quality information, that is trustworthy and reliable.
