Does native osteoprotegerin gene transfer inhibit the development of murine osteolytic bone disease induced by tumor xenografts?
A lentiviral vector can efficiently transfer the native human OPG gene to myeloma cells ex vivo and inhibit myeloma-induced bone destruction, thereby suggesting a therapeutic potential for unmodified, native OPG gene transfer for osteoclast-dependent skeletal disorders.
This study demonstrates the sensitivity of the fetal myocardium to cardioplegic calcium concentration. Hypocalcemic cardioplegia provides superior preservation of systolic, diastolic, and contractile function of the fetal myocardium.
