Boothman Lab

The research lab of David A. Boothman is working to understand and exploit cell stress responses in cancer versus normal cells. Three ongoing projects in the laboratory focus on: 1) EMT, migration and metastasis and the influences of, or changes in, metabolism during TGFß1-driven EMT; 2) DNA double strand break (DSB) repair and the specific roles of RNA termination factors in R-loop resolution and DSB repair; and 3) NQO1-mediated programmed necrosis for improved therapy of cancers that have elevated levels of NAD(P)H:quinone oxidoreductase 1 (NQO1), including cancers of the lung (NSCLC), pancreas (PDAC), breast and prostate.

Active Research

Researchers in the Boothman laboratory focus on understanding cell stress responses and exploiting these for tumor-selective therapies. Research in the lab center on tTwo active projects. One is focused onexploiting elevated levels of the NAD(P)H:quinone oxidoreductase 1 (NQO1) for treatment of pancreatic, lung, breast, prostate, head and neck and ATRT (pediatric) cancers using unique NQO1 bioactivatable drugs. The other is studying and exploiting the functions of RNA termination factors (Kub5-Hera (RPRD1B), p15RS (RPRD1A), XRN2 and others) in carcinogenesis and for leveraging tumor vs normal tissue differences for therapy.

Exploiting NQO1 bioactivatable drugs for selective therapy of human cancers with elevated levels of NQO1

NQO01 is elevated in a vast majority of human solid cancers, specifically in nonsmall cell lung, pancreatic, breast and prostate cancers. This labhas developed two classes of NQO1 bioactivatable drugs, ß-lapachone and deoxynyboquinone derivatives that are bioactivated by NQO1 to produce massive levels of hydrogen peroxide and huge pools of NAD+. The DNA damage created by H2O2 leads to the hyperactivation of PARP1, which degrades NAD+ leaving cells deficient in NAD+, creating losses of carbon metabolic pools and NAD+ loss-dependent programmed necrosis cell death. This group of researchers has learned how to use these drugs in combination with base excision repair (BER) inhibitors, PARP inhibitors and ionizing radiation.

Role of specific RNA termination factors (rprD1B, RPRD1A, XRN2) in genetic instability and exploiting their loss for cancer-selective therapy

The lab has discovered that the specific loss of RNA termination factors leads to the creation of R-loops, which cause the formation of complex DNA double strand breaks (DSBs), leading to genetic instability. Studies here further showed that these same RNA termination factors (RPRD1A, RPRD1B or XRN2) are directly involved in DSB repair. Therefore loss of specific RNA termination factors can lead to the formation of DSBs that remain unrepaired causing enhanced genetic instability. Understanding the mechanism of these RNA termination factors in DSB repair has led to new ways to specifically treat cancers that have losses in these specific proteins. Recently, researchers found that loss of Kub5-Hera (K-H)/RPRD1B led to loss of CDK1 expression, loss of BRCA1 activation, leasing to a BRCAness phenotype. These cancer cells are hypersensitive to ionizing radiation or PARP inhibitors.

Research Funding

NIH/NCI, 5 R01 CA102792-15, PI:  Boothman, DA, 08/01/03-04/30/18

The aims of this grant are to exploit naturally elevated levels of NQO1 enzyme specifically in non-small cell lung cancer (NSCLC) patients using newly developed NSCLC animal models and novel targeted and non-targeted nanoparticle delivery methods. Researchers in the Boothman lab are developing novel pH-sensitive imaging of particles and drug and examining preclinical antitumor efficacy and pharmacology of these novel drug delivery vehicles. The lab is also developing novel prodrugs that are activated by tumor esterases. Overlap: None.

NIH/NCI, 1 R01 CA201489-02, PI: Boothman, DA, 07/01/2016-06/30/2021

This grant focuses on the lab’s discovery that Kub5/Hera (K-H) regulates RNAPII at specific genetic promoters that include CDK1. Loss of K-H expression results in CDK1-BRCA1p-HR function loss, and hypersensitizes cells to PARP inhibitors. Aim 1 focuses on determining the structure/function of K-H regulation of the CTD domain of RNPII binding to specific promoter regions of CDK1. Aim 2 studies examine the therapeutic index of K-H-deficient breast cancers that are, in turn, hypersensitive to PARP inhibitors. Overlap: None.

NIH/NCI, 1 R01 CA221158-01, PI: Boothman, DA, 07/01/2017-0630/2022

The goals of this grant are to explore the efficacy of Isobutyldeoxuynyboquinone (IB-DNQ), a novel NQO1 bioactivatable drug for use with PARP inhibitors (Aim 1), as a producer of bystander effects (aim 2) and for efficacy against NSCLCs (Aim 3). Overlap: None.

NIH/NCI, 1R01 R01CA224493, PI: Boothman, DA, 12/01/2017-11/30/2022

To examine the mechanism of action of the IR + NQO1 bioactvatable drug synergy, DNA double strand break repair (Aim 1), changes in carbon metabolism (Aim2) and overall efficacy (Aim 3) are examined. Overlap: None.

NIH/NCI, U01CA215848, PI: Melissa Kemp, GA Tech,  09/1/2017-08/31/2022

Co-Is: Boothman, DA (UTSW) and Furdui, C (WFCC). The goals of this grant are to understand the systems biology of NAD+ metabolism and then alter NAD+ enzymes to improve therapy of NQO1 bioactivatable drugs for the treatment of NQO1 elevated head and neck cancer. Overlap: None.
