Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Purpose: Valproic acid(VPA) has anti-cancer activity attributed to histone deacetylase inhibition(HDACi). We published the GenomicallyDerived Sensitivity Signature for VPA(GDSS-VPA), a gene expression biomarker predicting breast cancer sensitivity to VPA in vitro and in vivo. We conducted a window-of-opportunity study examining the tolerability of VPA and the ability of the GDSS-VPA to predict biologic changes in breast tumors from VPA.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Drug resistance is a major obstacle in cancer therapy. The molecular mechanisms of drug resistance still remain largely elusive. Microarray analyses on paired primary myeloma samples at baseline and after therapy or at relapse showed that NEK2 was one of the most up-regulated genes in myeloma cells after high-dose chemotherapy or at relapse. By analyzing the published (> 2,500) microarrays and clinical datasets, we found that NEK2 expression is increased in many malignancies, and that high expression of NEK2 was associated with a shorter event-free and overall survival. Moreover, NEK2 expression was typically increased in tumors with aggressive subtype and advanced TNM stage. Our studies indicate that over-expressing NEK2 in cancer cells resulted in enhanced cell proliferation and drug resistance, whereas knockdown of NEK2 induced significant cancer cell death and growth inhibition. We found that NEK2 over-expression activates cell cycle progression and cell division through the stimulation of cell cycling genes CDC2/CCNB1 and PBK. Interestingly, NEK2-overexpression also activated the Wnt/-catenin signaling pathway. We conclude that NEK2 represents a predictor for drug resistance and poor prognosis in cancers and could be a potential target for cancer therapy.
Publication Title
NEK2 induces drug resistance mainly through activation of efflux drug pumps and is associated with poor prognosis in myeloma and other cancers.
