Cancer - Interactions investigated in the context of cancer Regarding the cell line U87 (U87MG): Text from Cellosaurus U-87MG ATCC (CVCL_0022) entry:- The cell line distributed by most cell collections (including ATCC, CLS, ECACC, etc.) is a different cell line (from the original U87) whose origin is not yet clear (PubMed=27582061, 2016). It states:-"the DNA profile of the widely used glioma cell line U87MG is different from that of the original cells and that it is likely to be a bona fide human glioblastoma cell line of unknown origin." It is not known if this is the original U87 cell line or not. U87MG (PTEN mutant) glioblastoma cells either expressing EGFRvIII/EV or coexpressing EGFRvIII and SIRPA proteins. The exact sequence or origin of EGFRvIII is not stated in this publication. As the exact sequence of this variant varies (see PMID: 29660021) the sequence has been taken from Uniprot -notably VAR_066493; this variant has only the commonly stated deletion of exons 2-7, resulting in a receptor that lacks amino acids 6–273 of the ecd, and no further insertions or mutational events are quoted. Transfected SIRPA was of Human origin based on Wu-2000 (PMID:10962556). Transfected EGFRvIII has been assumed to be of Human origin based on several references quoted. donald.orourke@uphs.upenn.edu Accepted 2020-MAY-11 AT 13:08 BST AT 13:08 BST by KALPANAP Oncogene 2010
