My laboratory concentrates on understanding the complex biological mechanisms that allow cancer cells to thrive in the hypoxic tumor microenvironment, with a focus on understanding how we can exploit such pathways to oppose the oncogenic properties of tumor hypoxia. In particular, we are currently focused on understanding how the Proviral Integration site for Moloney murine leukemia virus (PIM) kinases regulation of tumor angiogenesis and response to therapy. This research will be the first to describe a novel signaling pathway discovered in our lab in which PIM kinases control the amplitude of hypoxia-inducible factor-1 (HIF-1) signaling. Our working model places PIM kinases upstream of HIF-1 in the cellular response to hypoxia, making it a promising target for hypoxia-targeted therapy. We have developed innovative biochemical and imaging techniques to understand how aberrant PIM expression/activity impacts tumor angiogenesis and resistance to therapy in vitro and in vivo. Of particular significance, our preliminary data provide the rationale for a novel therapeutic strategy combining small molecule PIM kinase inhibitors and anti-angiogenic drugs that has the potential to change how we treat hypoxic tumors. My training is in two areas: cancer biology, focused on signal transduction, and drug development, focused on identifying and exploiting hypoxia in solid tumors; these skills remain pillars of my current research program studying prostate cancer biology and barriers to its effective treatment. My background greatly influences the approach I am currently taking to investigate the the cellular response to hypoxia, and this work will distinguish my laboratory as we pursue biological avenues that may have been overlooked by others.
In addition to my passion for research, I have taken advantage of the opportunity to serve as a mentor to clinical fellows, undergraduate, and graduate students. Since arriving at Univ. of Arizona, I have served as a mentor to Alva Sainz, a talented undergraduate in the UROC program. Her work will be included in two manuscripts, and she has recently been accepted into several graduate programs to study cancer biology. In addition, I had my first ABBS student, Andrea Casillas, rotate in my lab this winter. Her rotation project was to generate and characterize a somatic mutation in HIF-1 that is widely observed in clinical samples. In addition to my training, I have learned from mentoring students in my own lab. As a result, I have confidence in my ability to effectively train students in both the conceptual and technical aspects of how to study cancer biology through hypothesis driven science. I am extremely interested in serving as a mentor to train the next generation of scientist in cancer biology. In the coming year I hope to recruit a graduate student into my lab and train another undergraduate.

Molecular cancer therapeutics, 15(7), 1637-47.More infoIntratumoral hypoxia is a significant obstacle to the successful treatment of solid tumors, and it is highly correlated with metastasis, therapeutic resistance, and disease recurrence in cancer patients. As a result, there is an urgent need to develop effective therapies that target hypoxic cells within the tumor microenvironment. The Proviral Integration site for Moloney murine leukemia virus (PIM) kinases represent a prosurvival pathway that is upregulated in response to hypoxia, in a HIF-1-independent manner. We demonstrate that pharmacologic or genetic inhibition of PIM kinases is significantly more toxic toward cancer cells in hypoxia as compared with normoxia. Xenograft studies confirm that PIM kinase inhibitors impede tumor growth and selectively kill hypoxic tumor cells in vivo Experiments show that PIM kinases enhance the ability of tumor cells to adapt to hypoxia-induced oxidative stress by increasing the nuclear localization and activity of nuclear factor-erythroid 2 p45-related factor 2 (Nrf2), which functions to increase the expression of antioxidant genes. Small molecule PIM kinase inhibitors prevent Nrf2 from accumulating in the nucleus, reducing the transcription of cytoprotective genes and leading to the build-up of intracellular reactive oxygen species (ROS) to toxic levels in hypoxic tumor cells. This toxic effect of PIM inhibitors can be successfully blocked by ROS scavengers, including N-acetyl cystine and superoxide dismutase. Thus, inhibition of PIM kinases has the potential to oppose hypoxia-mediated therapeutic resistance and induce cell death in the hypoxic tumor microenvironment.

Pharmacology & therapeutics, 151, 41-9.More infoThe initiation and progression of human cancer is frequently linked to the uncontrolled activation of survival kinases. Two such pro-survival kinases that are commonly amplified in cancer are PIM and Akt. These oncogenic proteins are serine/threonine kinases that regulate tumorigenesis by phosphorylating substrates that control the cell cycle, cellular metabolism, proliferation, and survival. Growing evidence suggests that cross-talk exists between the PIM and Akt kinases, indicating that they control partially overlapping survival signaling pathways that are critical to the initiation, progression, and metastatic spread of many types of cancer. The PI3K/Akt signaling pathway is activated in many human tumors, and it is well established as a promising anticancer target. Likewise, based on the role of PIM kinases in normal and tumor tissues, it is clear that this family of kinases represents an interesting target for anticancer therapy. Pharmacological inhibition of PIM has the potential to significantly influence the efficacy of standard and targeted therapies. This review focuses on the regulation of PIM kinases, their role in tumorigenesis, and the biological impact of their interaction with the Akt signaling pathway on the efficacy of cancer therapy.

Small-Molecule NSC59984 Restores p53 Pathway Signaling and Antitumor Effects against Colorectal Cancer via p73 Activation and Degradation of Mutant p53. Cancer research, 75(18), 3842-52.More infoThe tumor-suppressor p53 prevents cancer development via initiating cell-cycle arrest, cell death, repair, or antiangiogenesis processes. Over 50% of human cancers harbor cancer-causing mutant p53. p53 mutations not only abrogate its tumor-suppressor function, but also endow mutant p53 with a gain of function (GOF), creating a proto-oncogene that contributes to tumorigenesis, tumor progression, and chemo- or radiotherapy resistance. Thus, targeting mutant p53 to restore a wild-type p53 signaling pathway provides an attractive strategy for cancer therapy. We demonstrate that small-molecule NSC59984 not only restores wild-type p53 signaling, but also depletes mutant p53 GOF. NSC59984 induces mutant p53 protein degradation via MDM2 and the ubiquitin-proteasome pathway. NSC59984 restores wild-type p53 signaling via p73 activation, specifically in mutant p53-expressing colorectal cancer cells. At therapeutic doses, NSC59984 induces p73-dependent cell death in cancer cells with minimal genotoxicity and without evident toxicity toward normal cells. NSC59984 synergizes with CPT11 to induce cell death in mutant p53-expressing colorectal cancer cells and inhibits mutant p53-associated colon tumor xenograft growth in a p73-dependent manner in vivo. We hypothesize that specific targeting of mutant p53 may be essential for anticancer strategies that involve the stimulation of p73 in order to efficiently restore tumor suppression. Taken together, our data identify NSC59984 as a promising lead compound for anticancer therapy that acts by targeting GOF-mutant p53 and stimulates p73 to restore the p53 pathway signaling.
