ZIC5 Drives Melanoma Aggressiveness by PDGFD-Mediated Activation of FAK and STAT3.

Insights into mechanisms of drug resistance could extend the efficacy of cancer therapy. To probe mechanisms in melanoma, we performed siRNA screening of genes that mediate the development of neural crest cells, from which melanocytes are derived. Here, we report the identification of ZIC5 as a mediator of melanoma drug resistance.

Identification of novel small compounds that restore E-cadherin expression and inhibit tumor cell motility and invasiveness.

Tumor dissemination and invasive behavior are associated with a majority of cancer-related mortality cases. Loss of E-cadherin, which is caused by several tumor-promoting factors, is associated with metastasis and poor prognosis in many neoplasms. In this study, we aimed to identify small molecule compounds that restore the expression of E-cadherin, because these molecules are most likely to suppress tumor malignancy by restoring E-cadherin function and/or by inhibiting signals that suppress E-cadherin expression.
