Targeting cellular heterogeneity with CXCR2 blockade for the treatment of therapy-resistant prostate cancer.

Hormonal therapy targeting androgen receptor (AR) is initially effective to treat prostate cancer (PCa), but it eventually fails. It has been hypothesized that cellular heterogeneity of PCa, consisting of AR+ luminal tumor cells and AR- neuroendocrine (NE) tumor cells, may contribute to therapy failure. Here, we describe the successful purification of NE cells from primary fresh human prostate adenocarcinoma based on the cell surface receptor C-X-C motif chemokine receptor 2 (CXCR2). Functional studies revealed CXCR2 to be a driver of the NE phenotype, including loss of AR expression, lineage plasticity, and resistance to hormonal therapy. CXCR2-driven NE cells were critical for the tumor microenvironment by providing a survival niche for the AR+ luminal cells. We demonstrate that the combination of CXCR2 inhibition and AR targeting is an effective treatment strategy in mouse xenograft models. Such a strategy has the potential to overcome therapy resistance caused by tumor cell heterogeneity.

Targeting androgen receptor-independent pathways in therapy-resistant prostate cancer.

Since androgen receptor (AR) signaling is critically required for the development of prostate cancer (PCa), targeting AR axis has been the standard treatment of choice for advanced and metastatic PCa. Unfortunately, although the tumor initially responds to the therapy, treatment resistance eventually develops and the disease will progress. It is therefore imperative to identify the mechanisms of therapeutic resistance and novel molecular targets that are independent of AR signaling. Recent advances in pathology, molecular biology, genetics and genomics research have revealed novel AR-independent pathways that contribute to PCa carcinogenesis and progression. They include neuroendocrine differentiation, cell metabolism, DNA damage repair pathways and immune-mediated mechanisms. The development of novel agents targeting the non-AR mechanisms holds great promise to treat PCa that does not respond to AR-targeted therapies.

Assaying Radiosensitivity of Ataxia-Telangiectasia.

Ataxia-Telangiectasia (A-T) is a prototypical genomic instability disorder with multi-organ deficiency and it is caused by the defective function of a single gene, ATM (Ataxia-Telangiectasia Mutated). Radiosensitivity, among the pleiotropic symptoms of A-T, reflects the basic physiological functions of ATM protein in the double strand break (DSB)-induced DNA damage response (DDR) and also restrains A-T patients from the conventional radiation therapy for their lymphoid malignancy. In this chapter, we describe two methods that have been developed in our lab to assess the radiosensitivity of A-T patients: (1) Colony Survival Assay (CSA) and (2) Flow Cytometry of phospho-SMC1 (FC-pSMC1). The establishment of these more rapid and reliable functional assays to measure the radiosensitivity, exemplified by A-T, would facilitate the diagnosis of other genomic instability genetic disorders as well as help the treatment options for most radiosensitive patients.
