Osteoporosis is a complex multifactorial bone disease with a strong genetic component. Among the various genes implicated in the progression of osteoporosis, those encoding G-protein-coupled receptors (GPCRs) play a crucial role in its pathogenesis. This superfamily of membrane receptors regulates myriad of cellular events including physiological and pathological processes in bone tissue.

Dihydrofolate reductase-deficient DXB-11 cell line, one of the first CHO derivatives, serves as the host cell line for the production of therapeutic proteins. It is generally assumed that DXB-11 is identical to DUKX or CHO-DUK cell lines, but, to our knowledge, DXB-11 karyotype has not been described yet.

Chromosome numbers retained near-diploid (L363, Karpas 707 and U-266) or increased to hypotriploid (RPMI 8226) during many years of maintenance of the cell lines in vitro. Based on G-banding analysis, the complex karyotypes with abnormalities of virtually all chromosome pairs were found in these cell lines but common chromosome translocations were not observed.
