## Research

Harris has made many major discoveries in cancer research. One of the most notable is his seminal work describing the first-known molecular link between an environmental carcinogen, aflatoxin B1, and a specific mutation at codon 249 of the p53-encoding TP53 gene in hepatocellular carcinoma (Nature 350:427, 1991 and web of science). This discovery was selected by the AACR as a Centennial Landmark in Cancer Research. In addition, his paper on the TP53 mutation spectrum is among the most highly cited in the biomedical research field, with over 9,000 citations and web of science (Science 253:49, 1991). These findings have had, and continue to have, a major impact in cancer risk assessment and biomarker discovery for cancer prevention, diagnosis and prognosis.
Harris's research has investigated mechanistic, translational, and functional links between population and basic science research. When the focus of cancer research was on in human vitro and in vitro animal models, he pioneered investigations of carcinogen metabolism, DNA damage, and DNA repair and mutagenesis in humans and in human tissues (e.g., Science 194:1067, 1976; Cancer Res 44:2855, 1984). Many of these studies were among the first to highlight the deleterious effects of tobacco carcinogens and their damage to human health (e.g., Cancer Res. 33: 2842–2848, 1973; Nature 247: 48–49, 1974, Nature 252: 68–69, 1974), providing an evidence base for tobacco control policies. Moreover, he led the development of first-in-kind in vitro models of human bronchial epithelial cells from patient explants (e.g., Cancer Res. 36: 1003–1010, 1976, Nature 252: 68–69, 1974). In parallel, he has extensively investigated p53 functions in the regulation of DNA repair, apoptosis, senescence, and tumorigenicity (e.g., Nat Genet. 10:188, 1995; Nat Med. 4:137,1998; Nat Cell Biol 11:1135, 2009; Nat Cell Biol, 12: 1205, 2010) and recently a microbiome – TP53 mutation interaction in human lung cancer, Genome Biology:19: 123–29, 2018.
Decades prior to the recent discovery of mutant TP53 cells in esophageal tissue (Cell Stem Cell 25:321-41, 2019; Science 362:911-17, 2018), Drs. Peter Cerruti and Curtis Harris, using the novel and highly sensitive TP53 mutational load assay, discovered TP53 mutant DNA in non-malignant lung and plasma in tobacco smokers (PNAS 97: 12770–5, 2000; Science 264: 1317–19, 1994; Cancer Res. 66: 8309–17, 2000). In the past decade, Harris has contributed substantially to research on TP53 mutations, as well as TP53 isoforms and their effects on senescence, aging and cancer (Fujita K, et al., Nat Cell Biol 11:1135–41, 2009; Mondal A, et al., J Clin Invest 123:5247-57, 2013; Turnquist C. et al., Cell Death Differ 23: 1515–28,2016; Hirokawa I. et al., Cell Death Differ 24: 1017–28, 2017; Von Muhlinen N., et al., Oncogene 37: 2379–93, 2018; Mondal, AM. et al., Cell Death and Dis 9: 750–804, 2018; Turnquist C. et al., Neuro Oncology 21: 474–85, 2019).
Translational Discoveries in Cancer Biomarkers: Harris's research aims to identify mechanistic and statistically independent biomarkers of cancer risk, diagnosis, prognosis, and therapeutic outcomes, using data from multiple ethnic and geographic cohorts. One mechanistic facet of these studies is chronic inflammation, a feature of the internal exposome (initially described by Chris Wild, Cancer Epi Biomarkers Prev 14: 1847, 2005) and an established cancer risk factor. He reported findings that increased levels of circulating interleukins are predictors of cancer risk, diagnosis, and prognosis of lung cancer patients (JNCI 99:1401, 2007; JNCI 103:1112, 2011). He also identified microRNAs associated with both diagnosis and prognosis of lung cancer (Cancer Cell 9:189, 2006; Clin Cancer Res 17: 1875, 2011) and prognosis and therapeutic outcome of colon cancer (JAMA 299:425, 2008). In addition, he reported that combinations of DNA methylation, microRNAs, and proteins (e.g. inflammation-related) produced by human lung, colon, and esophageal carcinomas are robust cancer prognostic classifiers (PNAS 106:12085, 2009; Clin Cancer Res 15:5878, 2009; Clin Cancer Res 15:6192, 2009; Clin Cancer Res 16:5824, 2010; Clin Cancer Res 17:1875, 2011; Int J Cancer 132:2901, 2013; Cancer Res 73:3821, 2013, J of Thoracic Oncology, 10: 1037–1048, 2015). Importantly, these studies identified early-stage lung and colon cancers that have poor prognoses due to the likelihood of undetected micrometastasis.
Over the past ten years, Harris has conducted several novel studies of the human metabolome and how it contributes to cancer risk assessment, cancer diagnosis and the accurate identification of early stage lung cancer patients at high-risk of tumor recurrence (Cancer Res. 74: 3259–3270, 2014; Cancer Epidemiology, Biomarkers & Prevention 25(6); 978–86, 2016).
