MOA of PDC
Overall, these results indicate that both conjugates alter cell migration in either TNBC or ovarian cancer cell models through a SORT1-dependent mechanism. The effects of TH1902 and TH1904 on cell migration further support the molecular rationale that inhibition of VM activity may result, in part, from the reduction of cancer cell invasive phenotype.
