Identification and use of small molecule biomodulators as novel anticancer drugs and probes for new regulatory pathways
Small molecule biomodulators for studying and treating cancer
Our previous research focused on mechanisms of steroid receptor regulated transcription and posttranscriptional control of mRNA degradation. We used these skills to develop powerful high throughput screening platforms for identifying small molecule modulators of steroid hormone receptor and mRNA binding protein action.
Estrogen and androgen receptor action in cancer
Steroid hormones, such as estrogens, act by binding to specific receptor proteins called steroid/nuclear receptors. In the nucleus, these receptors regulate gene expression. In the cytosol, they regulate signaling pathways. The estrogen and androgen (testosterone) receptors (ER) and (AR) stimulate cell proliferation. Estrogens, acting through the ER, are implicated in the growth and metastases of breast, ovarian, endometrial and lung cancer. Testosterone, acting through the AR, plays a key role in prostate cancer. Over time tumors become resistant to current therapies targeting estrogen action, and tumor growth resumes with few therapeutic options. We identify and develop new small molecule inhibitors that are effective against tumors resistant to current therapies.
A novel strategy for identifying new regulatory pathways and anticancer drugs
Our approach is a novel way to do molecular biology in which unbiased high throughput screening is used to “ask the cell” to identify new pathways. We screen to develop a large database, and use simple follow-on assays and bioinformatics to identify small molecule biomodulators likely to exhibit a previously undescribed mode of action. Confirming the potential of this new strategy, our lead estrogen receptor anticancer drug candidate both induces rapid tumor regression and works by hyperactivating a normal, and previously undescribed, pathway of estrogen action in cancer. Graduate students presented 2 talks on this work at the biennial June 2014 International Congress of Endocrinology (Andruska N, Yang Mao C, Cherian M, Mahapatra L, Helferich WJ and Shapiro DJ. 2014. A Small Molecule Inhibitor Reveals a Novel Pathway of Estrogen Receptor α Action and Induces Regression of Breast Cancers, and Zheng X, Andruska, N and Shapiro DJ. 2014. A Small Molecule Inhibitor Blocks Proliferation of Ovarian Cancer Cells and Restores Sensitivity to Taxanes.)
Four papers describe this ongoing work. One paper is in press in Oncogene, one is in revision at PNAS and 2 are being written.
We also developed what is likely the first small molecule inhibitor of an oncogenic mRNA binding protein. Our inhibitor of the oncogenic mRNA binding protein IMP-1/IGF2BP1 targets oncogene mRNAs and inhibits proliferation of diverse cancer cells.
