Translational Breast Cancer Research
A postdoctoral training position is available in the laboratory of Carlos L. Arteaga, M.D. in the Simmons Comprehensive Cancer Center at UT Southwestern Medical Center, Dallas, TX. The laboratory has a longstanding interest in understanding the molecular pathways that drive breast cancer progression and influence response to therapies.
Our laboratory has a strong translational focus, aimed at developing therapeutic strategies and identifying biomarkers of drug sensitivity and resistance.
Current projects include:
• Discovery of mechanisms of resistance to breast cancer therapies (i.e., estrogen receptor antagonists,
CDK4/6 inhibitors, HER2 inhibitors, PI3K/AKT inhibitors)
• Genomic profiling of drug-resistant breast cancers
• Identifying rational combinations to overcome resistance to targeted therapies
We incorporate molecular profiling (next-gen DNA/RNA sequencing) of patient tumors, CRISPR, forward genetics, and gain-of-function ORF screens, and mechanistic studies using breast cancer cell lines, cell linederived xenografts, and patient-derived organoids and xenografts, with the goal of using insights from the laboratory to guide clinical trials.
Relevant recent publications that apply to these topics include:
• Proline rich 11 (PRR11) overexpression amplifies PI3K signaling and promotes antiestrogen resistance in breast cancer. Nat Commun. 2020 Oct 30;11(1):5488.
• Hyperactivation of TORC1 Drives Resistance to the Pan-HER Tyrosine Kinase Inhibitor Neratinib in HER2-Mutant Cancers. Cancer Cell. 2020 Feb 10;37(2):183-199.e5.
• Aberrant FGFR signaling mediates resistance to CDK4/6 inhibitors in ER+ breast cancer. Nat Commun. 2019 Mar 26;10(1):1373.
• ER+ Breast Cancers Resistant to Prolonged Neoadjuvant Letrozole Exhibit an E2F4 Transcriptional Program Sensitive to CDK4/6 Inhibitors. Clin Cancer Res. 2018 Jun 1;24(11):2517-2529.
• Genomic profiling of ER+ breast cancers after short-term estrogen suppression reveals alterations associated with endocrine resistance. Sci Transl Med. 2017 Aug 9;9(402):eaai7993.
• An Acquired HER2(T798I) Gatekeeper Mutation Induces Resistance to Neratinib in a Patient with HER2 Mutant-Driven Breast Cancer. Cancer Discov. 2017 Jun;7(6):575-585.
Applicants with a recent Ph.D., M.D., or M.D./Ph.D. and a strong background in molecular & cell biology and genomics with an interest in translational research are encouraged to apply. A track record of productivity and publications in well-established journals is essential.
