Biosketch

Feyruz V. Rassool, PhD, received her doctorate at the Royal Postgraduate Medical School, University of London, UK. She did her postdoctoral training at the University of Chicago and assumed her first independent faculty position studying DNA damage and repair in myeloid malignancies at King’s College London. She has been at the University of Maryland for the last 16 years.

She is an expert in repair of potentially lethal forms of DNA damage, DNA double-strand breaks (DSBs), that play a critical role in generating genomic instability in cancer. Her work has specifically focused on the aberrant expression and activity of these repair pathways in cancer and leukemia cells that not only play a role in genomic instability, but also appear critical for cancer cell survival. These DNA repair components are attractive therapeutic targets. Thus, Dr. Rassool’s work provides a framework for the development and translation of novel therapeutic strategies for patients with leukemia’s and other cancers. Her recent work is focused on targeting DNA repair abnormalities in Cancer and leukemia for therapy.

Dr Rassool recently received the Ziskin Award to study the intersection between DNA damage and repair and epigenetic pathways in cancer and she is part of the SU2C stand-up to cancer Epigenetics Dream Team.

Studies to target acute myeloid malignancies and triple negative breast cancers with a combination of DNA repair and epigenetic inhibitors was recently published in Cancer Cell (2016). These studies led to a clinical trial in AML led by Dr Maria Baer, Director of hematologic malignancies at UMGCCC.  A clinical trial in TNBC based o this treatment paradigm was also opened at Indiana University, in collaboration with Dr. Kenneth Nephew and Kathy Miller.  The Rassool group has also extended this therapy paradigm to lung cancer.  The study showed that the efficacy of this drug combination in non-small cell lung cancer (NSCLC) is further enhanced with ionizing radiation (IR) (PNAS, 2019).  Notably this data suggests that DNMTis iduce a DNA double strand break repair defect that sensitizes cells to PARPis and IR.

 

The recent studies in the Rassooll group have linked decreased DSBR with the drug combination to activation of immune signaling.  This work is based on a report that low does of DNMTis induce an increased tumor immune response through the activation of endogenous retrovirus transcription, and a cytopllasmic double stranded RNA (dsRRNA) response.  This has been termed the DNMTi-induced iral mimiry (Chiappinelli et al., 2015; Chiappinelli et al., 2016).  Importantly, the Rassool lab has extended this concept by showing that DNMTi's in combination with PARPis induuce interferon and inflammasome signaling they termed pathogen mimicry response (PMR), leading to decreased DSBR (PNAS, 2019, PNSA, 2020).

Research Interests

Dr Rassool’s work focuses on repair of potentially lethal forms of DNA damage, DNA double strand breaks (DSBs). She reported that an abnormal and highly error-prone version of DSB repair in cancer cells plays a critical role in generating genomic instability. In addition, this abnormal repair pathway appears critical for the survival of leukemia cells but not normal cells, and thus may be an attractive therapeutic target. Importantly, Dr Rassool’s work provides a framework for the development of novel therapeutic strategies in leukemias and other cancers in which abnormal DSB repair is observed. 

Both in collaboration and independently, Dr Rassool has extended her work to the development of therapeutic strategies in leukemias and breast cancers that are resistant to standard therapies.  One important collaborator in her efforts to target abnormal repair in therapy resistant breast cancer, is the world famous breast cancer researcher at the University of Maryland, Dr Angela Brodie. In their recently published manuscript in Molecular Cancer Research, they demonstrated that hormone therapy-resistant breast cancer cells exhibit significantly increased abnormal repair involving DNA ligase IIIa and poly ADP ribose polymerase (PARP-1), and that these cells are highly sensitive to a combination of PARP and DNA ligase III inhibitors. These results suggest that abnormal DSB repair may serve as biomarkers to identify tumors that are candidates for this therapeutic approach. Importantly, this recently published study was selected to be featured in the "MOLECULAR CANCER RESEARCH Highlights”.

Her work has also involved mechanisms by which embryonic stem cells (ESCs) maintain genomic integrity in response to environmental stress, compared with differentiated cells. Her lab has recently reported that human embryonic stem cells (hESCs) employ at least two strategies to maintain genomic integrity: First, they maintain enhanced levels of DSB repair transcripts and proteins and have high repair efficacy, as evidenced by established NHEJ assays. Second, they are highly sensitive to DNA damage, as evidenced by a high level of apoptosis upon irradiation. Importantly, adult somatic cells, “reprogrammed” to “dedifferentiate” into induced Pluripotent Stem Cells (iPSCs), mimic hESCs in their repair protein expression and repair efficacy, indicating that their DDR pathways are reprogrammed to resemble those of hESCs. In contrast, the differentiated parental cells from which iPSCs are derived have decreased expression of DSB repair components and demonstrate low repair activity and efficacy. Importantly, we have demonstrated that the DNA damage response is an important biomarker for successful reprograming of adult cells into pluripotent stem cells (IPSCs). This work is vital to the future use of IPSCs in regenerative medicine and has resulted in a published manuscript and RO1-equivalent funding from the Maryland Stem Cell Fund.

Most recently, and inspired by the Laura Zisken award in 2012, Dr Rassool has shown that DNA repair and epigenetic pathways interact and that a combination of DNA methyltransferase inhibitors (DNMTi) and PARP inhibitors (PARPi) work synergistically to trap more PARP, leading to dramatic anti-tumor effects in AML and breast cancers with intact BRCA genes. This work was published in Cancer Cell (2010) and has led to clinical trials in AML and TNBC funded by the SU2C.  Her most recent studies in multiple cancers have linked the effects of the DNMTi-PARPi combination to activating STING-dependent immune reponses, leading to decreased DNA repair (2019, 2020).  Studies are underway in her lab to elucidate these effects mechanistically.  Importantly, these effects in the setting of AML appear to be enhanced in cells with TP53 mutations, suggesting a way of personalizing the therapy combination.

 

Current projects in the laboratory:

Mechanistic studies linking activation STING-dependent interferon/inflammasome signaling with PARPi and DMNTis to induction of DNA repair defects in breast, ovarian lung and AML.

Mechanistic studies linking activation STING-dependent interferon/inflammasome signaling with PARPi and DMNTis to mitochondrial dysfunction in cancer.

Mechanistic studies linking activation STING-dependent interferon/inflammasome signaling with PARPi and DMNTis to suppression of metastatic pathways.

SPNew Treatment Combination Could Work Against Broader Array of Cancer Cells, Study Finds

University of Maryland School of Medicine Researchers Find Two Drugs Work Together to Disrupt Cancer Cells’ Ability to Survive
In continuing efforts to find novel ways to kill cancer cells, researchers at the University of Maryland School of Medicine (UMSOM) have identified a new pathway that leads to the destruction of cancer cells. The new finding, published this week in the journal PNAS, could pave the way for the broader use of a class of anticancer drugs already on the market. These drugs, known as PARP inhibitors, are currently approved by the FDA to treat only a limited group of breast and ovarian cancers associated with BRCA gene mutations.

In a proof of concept study, the researchers demonstrated that combining a PARP inhibitor with a DNA methyltransferase (DNMT) inhibitor delivered a one-two punch to non-small cell lung cancer tumors, which are normally not associated with mutations in BRCA genes. The research, conducted in mouse models and cell lines, outlines the mechanistic action of the combination. The DNMT inhibitor triggers an effect that mimics a BRCA mutation in the cancer cell so the cell responds to the lethal effects of the PARP inhibitor, which prevents repair of damage to a tumor cell’s DNA, triggering cell death...

New Drug Combination Targets Aggressive Blood Cancer

Date: March 7, 2017

Van Andel Research Institute
Published by: ScienceDaily

A pair of drugs that may be a one-two punch needed to help combat acute myeloid leukemia (AML), an aggressive blood cancer that kills nearly three-fourths of patients within five years of diagnosis, is the focus of a new multi-center clinical trial that will enroll patients at three sites across the U.S.

The trial pairs an investigational PARP inhibitor, talazoparib, with the DNA methyltransferase (DNMT) inhibitor decitabine, which is already approved for the treatment of myelodysplastic syndrome (MDS), a disease that often precedes AML. Preclinical studies show that combining the drugs may maximize their ability to kill cancer cells.

“Long-term survival with AML is quite poor and, unfortunately, our arsenal for treating it has remained largely unchanged for decades,” said Feyruz Rassool, Ph.D., an associate professor of radiation oncology at the University of Maryland School of Medicine, a researcher at the Marlene and Stewart Greenebaum Comprehensive Cancer Center, and a member of the Van Andel Research Institute–Stand Up To Cancer (VARI–SU2C) Epigenetics Dream Team. “Combination therapies, such as talazoparib and decitabine together, allow us to attack cancer from multiple angles at the most basic level for a greater potential effect.”
