Research Statement
Supplemental Microarray Data, Loercher, et al. June 2004.
The Tumor Biology Section, Head and Neck Surgery Branch of the NIDCD conducts clinical studies and trials concerning the pathogenesis, prevention, diagnosis, and treatment of neoplasms of the head and neck region that affect human communication. Squamous cell carcinoma is the most prevalent malignancy involving the upper aerodigestive tract which affects voice, speech, taste, smell, hearing, and balance as well as survival. Over 42,000 Americans develop neoplasms of the upper aerodigestive tract each year, and approximately 320,000 Americans currently alive suffer significant impairment of communication and other disability as a result of tumor destruction or ablative surgical and radiation therapy. Despite therapy, over 12,000 of these patients in the U.S. die of disease annually. New modalities for prevention and therapy are needed in order to improve preservation of function and survival.
Accomplishments
Signal transcription factors in head and neck cancer
A major focus of the Tumor Biology Section (TBS) has been to identify and determine the mechanisms of activation of key signal activated transcription factors responsible for altered gene and protein expression and molecular pathogenesis, that may serve as molecular targets for prevention and therapy of HNSCC. Our laboratory discovered that transcription factor Nuclear Factor-kappaB, initially identified as a transient activator of genes in response to injury and infection, is aberrantly turned on in HNSCC (Ondrey, Mol Carcinogenesis, 1999). NF-kappaB was found to be a key regulator of cancer cell survival and the multiple cytokines and factors that promote inflammation, angiogenesis and tumorigenesis (Duffey, Cancer Res, 1999; Dong, Cancer Res, 1999). Using microarray gene expression profiling, we further showed that as many as ~60 percent of the genes abnormally expressed in murine and human SCC are NF-kappaB regulated genes, and their expression and the malignant phenotype may be reverted by inhibition of NF-kappaB (Dong Cancer Res, 2001; Loercher, Cancer Res, 2004; Yan, Genome Biology, 2007; Lee, Clin Cancer Res, 2007). We have further demonstrated that NF-kappaB is part of a network of injury signal transcription factors altered in HNSCC. NF-kappaB contributes to activation of other prosurvival pathways and genes, such as IL-6-mediated STAT3 activation, and inhibition of pro-death pathways, notably tumor suppressor p53 (Hong, FASEB J. 2000; Friedman, Clin Cancer Res, 2007; Lee, Int J Cancer, 2008). Using a systems biology approach, we have recently shown important links between NF-kappaB, other pathways and gene expression patterns in HNSCC (Yan, Genome Biol, 2008). Through a collaboration with Dr. Wendy Weinberg of the FDA, a novel interaction between subunits of the NF-kappaB cREL and p63 deltaNp63 family subunits in regulating p21 and cell growth of normal keratinocytes, and their aberrant activation in HNSCC was demonstrated (King, Cancer Res, 2008).
Signal cytokines in molecular pathogenesis and as biomarkers
Clinical studies showed that NF-kappaB related and other signal cytokines and growth factors that promote inflammation and blood vessel formation such as IL-1, IL-6, IL-8, GRO-1, GM-CSF, HGF and VEGF are constitutively expressed by human HNSCC (Chen, Clin Cancer Res, 1999; Dong, Cancer Res, 2001, Druzgal, Head Neck, 2005). Constitutive IL-1 expression was shown to be an autocrine activator of NF-kappaB and proliferation (Chen, Cancer Res, 1999; Wolf Clin Cancer Res, 2001). Autocrine and paracrine IL-6 was shown to promote STAT3 activation and proliferation (Hong, FASEB J, 2000). GRO-1 and its receptor CXCR2 were shown to be key factors in inflammation, angiogenesis and tumorigenesis in syngeneic and transgenic mice (Loukinova, Oncogene (Nature), 2000). HGF and its receptor c-MET were shown to be important in spread and metastasis (Dong, Cancer Res, 2001; Dong, Oncogene (Nature), 2004; Worden Cancer Res, 2005) Among these cytokines and factors, IL-6, IL-8, GRO-1, HGF, and VEGF were detected in the serum of patients with newly developed or recurrent head and squamous cell carcinoma (Chen, Clin Cancer Res, 1999; Dong, Cancer Res, 2004; Druzgal, Head Neck, 2005). The potential use of multiplex assay of these cytokines as serum proteomic biomarkers of response, recurrence and survival was demonstrated in a collaborative study with the NCI Specialized Program of Research Excellence (SPORE) at University of Michigan (Allen, Clin Cancer Res, 2007).
Molecular targeted therapy
After discovery of the role of NF-kappaB in molecular pathogenesis of HNSCC, we demonstrated that a novel first generation proteasome inhibitor (bortezomib, PS-341), was a potent inhibitor of NF-kappaB, cell proliferation, survival, cytokine expression, angiogenesis and tumorigenesis in preclinical studies (Sunwoo, Clin Cancer Res, 2001). The inhibition of NF-kappaB and the proteasome was shown to sensitize HNSCC to radiation, one of the major treatment modalities for HNSCC (Kato, Head Neck, 2000; Van Waes, Proteasome Inhibitors in Cancer Therapy, 2004). The NIDCD HNSB together with the NCI Radiation and Medical Oncology Branches conducted the first in human phase I study of a proteasome inhibitor with re-irradiation in patients with recurrent HNSCC (Van Waes, Int J Rad Oncol Biol Phys, 2005; Allen, Clin Cancer Res, 2008). With altered scheduling, we demonstrated the feasibility of this combination, as well as activity of bortezomib in inhibiting NF-kappaB, target genes, proliferation and survival, and serum cytokine biomarkers. This work has been translated to an NCI Eastern Oncology Cooperative Group Phase II two arm trial of bortezomib or bortezomib and irinotecan in recurrent HNSCC (ECOG 1304), which is nearing completion of accrual. The clinical activity of bortezomib alone and the combination, together with NF-kappaB serum cytokines as early pharmacodynamic proteomic markers is being investigated. Newly underway at NIH in Bethesda in collaboration with the NCI SPORE and Cancer Center at University of Pittsburgh is a phase I trial of bortezomib, cetuximab without or with cisplatin and radiation, as a possible next generation combination for advanced HNSCC. Preclinical studies of other molecular targeted combinations such as bortezomib with histone deacetylase inhibitors (Duan, Mol Cancer Ther, 2007) are also being translated in extramural phase I studies. Recently, the antimalarial and anti-inflammatory drug quinacrine and HSP90 inhibitors were shown to inhibit NF-kB, and to reactivate p53 in a subset of HNSCC (Friedman, Clin Cancer Res, 2007; Nottingham, Keystone Proceedings, 2008). Further studies to evaluate clinical potential of such agents are underway.
Molecular Prevention and Therapy
Premalignant precursors of HNSCC and other cancers may provide a window for molecular prevention. Such lesions commonly progress to invasive HNSCC in hereditary Fanconi Anemia, in which there are defects in the FA DNA repair pathway (Van Waes, Arch Otolaryngol Head Neck Surg, 2005). We demonstrated that a synthetic anti-oxidant, Tempol, could reduce oxidative DNA damage in FA fibroblasts, thereby raising the potential of Tempol to delay the onset of HNSCC and other cancers. These findings were reported together with the demonstration that Tempol delays the onset of epithelial malignancies and prolongs survival of transgenic Fancd2(-/-) p53 (+/-) mice with collaborators at Oregon Health Sciences University (Zhang, Cancer Res, 2008). Studies of natural and synthetic inhibitors of NF-kappaB activation have been of interest for chemoprevention of cancer (Van Waes, Clin Cancer Res, 2007). Inhibition of protein kinase CK2 and both Inhibitor Kappa B Kinases alpha and beta inhibit activation of NF-kappaB in HNSCC (Yu, Cancer Res, 2006), identifying these as potential targets for natural and synthetic agents.
