“Agarose gel electrophoresis showed the presence of low‐molecular weight deoxyribonucleic acid (DNA) fragments of adherent cells cultured with genistein (10−6 M) plus zinc (10−5 M) for 24 or 72 h, indicating that the combination of two chemicals induces apoptotic cell death.”
“Culture with genistein (10−6 M) plus zinc (10−5 M) for 72 h caused a significant increase in caspase‐3 mRNA expression in the presence or absence of M‐CSF and RANKL as compared with the value for each chemical alone.”
“This study demonstrates that the combination of genistein and zinc has potent stimulatory effects on apoptotic cell death and suppressive effects on osteoclastic cell function.”
