Dr. Lissette Delgado-Cruzata is Associate Professor of Molecular Biology in the Department of Sciences. She earned her Masters in Public Health and PhD at Columbia University, and her undergraduate degree at the University of Havana, Cuba. She started as a basic molecular biologist carrying out genetic research in yeast, but found that she could apply her skills to population studies integrating her molecular biology expertise to the understanding of disease etiology and progression. She is a molecular epidemiologist who studies chronic diseases and carries out molecular epidemiology studies investigating epigenetic biomarkers. She is also interested in the associations of these biomarkers with lifestyle and behavioral factors. Her current research explores epigenetic biomarkers in minority populations with the goal of decreasing health disparities. She conducts this work in US and Brazilian populations in projects funded by NIH and Fulbright. In both projects, she investigates the relationship between breast cancer mortality, DNA methylation and ancestry.  She collaborates with researchers at the New York site of the Breast Cancer Family Registry and Brazil's National Cancer Institute (INCA) located in Rio de Janeiro. She expects that these projects will increase our knowledge of the role DNA methylation plays in breast cancer mortality in women of mixed ancestry. 

Her teaching expands the undergraduate and graduate curriculum in the biological sciences. She has developed a new course, AFR/SCI 252 Race and Science, that explores the sociological and biological aspects of race. This course will be co-taught by Dr. Delgado-Cruzata and Dr. Adams from Africana Studies. She also developed and teaches the Cell and Molecular Biology capstone course (BIO488). In this course she guides students in the conception, writing and presentation of a research proposal in the topic of cancer biology. She is a  coordinator for BIO488 and BIO380, Topics of Cell and Molecular Biology. She also teaches in the Forensic Science Master program Advanced Genetics (FOS704) and Advanced Molecular Biology lab (FOS732). 

She is passionate about making the STEM field more inclusive and diverse. She approaches this by working in two main areas, student mentoring and research to expand STEM curricula to make it more inclusive, diverse  and student centered. Dr Delgado-Cruzata mentors many students in her research group and co-directs a peer-mentoring program for first-year female science students.  Students in her research group end up joining many graduate programs, she encourages her mentees to attend undergraduate conferences and explore opportunities outside the college. Recent mentees are currently enrolled in doctoral degree programs at Princeton, Stanford, Texas A&M, Rutgers and Cornell Universities. She has run a peer-mentoring program since 2020, with Dr Joyce Lau of the Science department, in which an average of 30 students participate.  Female science juniors and seniors act as mentors to first year female students, meeting monthly, attending meetings to learn about potential careers, and discussing strategies to overcome the challenges of transitioning from high school to college. The program enrolls mostly women of color, and aims to create a community of women at the college level that can support each other on their path as scientists. Dr Delgado-Cruzata is also currently the PI of a NSF-funded grant to train STEM faculty members to create new curricular materials that bring the experience of students and their identities to the center of the learning process. These initiatives and projects all have the common goal of building a future STEM workforce that resembles our society, and is open to all those interested in the sciences.

Research Summary

Dr. Delgado-Cruzata's group specializes in the study of epigenetic modifications such DNA methylation and micro RNAs (miRNAs), that regulate gene expression independently of changes in the DNA sequence. We carry out in vitro cell culture studies and clinical and/or population studies, to better understand disease etiology through our study of epigenetic modifications. We are currently working in three projects:

1. In one study we are determining DNA methylation biomarkers associations with breast cancer mortality in Hispanic women. We are studying the association of known DNA methylation epitypes with breast cancer mortality considering genetic ancestry. We will also identify new DNA methylation biomarkers specific to Hispanic women at high risk of breast cancer.

2. In another, we are identifying epigenetic biomarkers associated with rheumatoid arthritis in minority populations. Dr. Delgado-Cruzata is one of the PIs of the Epigenetics of Rheumatoid Arthritis (ERA) study, which is recruiting individuals in New York and collecting their specimens to determine whether changes in epigenetic biomarkers can inform clinicians about the severity of rheumatoid arthritis and aid in the development of new therapies.

3. In a third one, we are investigating the effect of chemicals in modulating the levels of miRNAs using high through-put Nanostring analysis. This project investigates how chemotherapeutic drugs (mitomycins) and dietary polyphenols (catechins) interact with miRNAs and potentially disrupt their regulation of important cellular pathways. This is a multidisciplinary project. It uses bioinformatic, organic chemistry and analytical techniques along with molecular biology methods to investigate the effects of these  chemicals in breast cancer cells. It is a collaboration with Drs Champeil, Proni, Cheng and Concheiro Guisan from our John Jay College's Science Department, and Dr Yoel Rodriguez from Hostos Community College.
