- A new subtype of bone sarcoma is defined by BCOR-CCNB3 gene fusion. (22387997)

  • CCNB3 immunohistochemistry is a powerful diagnostic marker for this subgroup of sarcoma and that overexpression of BCOR-CCNB3 or of truncated CCNB3 activates S phase in NIH3T3 cells.
  • The intrachromosomal X-chromosome fusion represents a new subtype of bone sarcoma caused by a newly identified gene fusion mechanism.
