# Role of MicroRNAs in malaria and sickle cell severity

> **NIH NIH K01** · MOREHOUSE SCHOOL OF MEDICINE · 2020 · $136,283

## Abstract

This is a K01 application by Dr. Adel Driss, a research instructor at MSM. Dr. Driss is establishing himself as a
young investigator pursuing research in global health to understand the molecular mechanisms mediating
interactions between hemoglobinopathies and Malaria. Although these two diseases overlap in sub-Saharan
Africa, the biological interactions between malaria and hemoglobinopathies are poorly understood. Dr. Driss
recently returned from Ghana after an eleven-month field study sponsored by a Fogarty Global Health Fellows
award to screen microRNA polymorphisms associated with severity of anemia in sickle cell and malaria in
Ghana. This collaborative research was conducted between MSM and the University of Ghana (UG). He
successfully obtained blood samples and clinical data and conducted preliminary analysis during his
fellowship. This K01 award will greatly enhance Dr. Driss' goals of: 1) developing a path to independence in
biomedical research; 2) conducting investigations on the role of microRNA's in the pathogenesis of malaria and
hemoglobinopathies; 3) applying advanced genomic and proteomic methods to identify and validate
biomarkers of malaria severity; and 4) developing global health collaborations between MSM in the USA and
UG in West Africa. To achieve these goals, Dr. Driss has assembled a mentoring team consisting of: Dr.
Stiles, Professor of Microbiology at MSM, who will provide support through his expertise in immuno-
pathogenesis of blood diseases and hemoglobinopathies; Dr. Wilson, Professor of Parasitology at Noguchi
Memorial Institute for Medical Research at the UG. Dr. Wilson will provide the necessary onsite support and
guidance in the Ghanaian host institution; Dr. Hibbert, Associate Professor and an expert in animal studies
relating to the role of nutrition in modulation of various human diseases will provide support for the proposed
animal studies; and Dr. Quarshie will provide statistical support. The rationale for the proposed study is that
specific host-derived microRNAs (miR-451 and Let-7i) have been associated with protection against the
Malaria parasite in individuals with sickle-cell trait. These findings have never been validated in a population-
based study. The hypothesis is that malaria severity is associated with alterations in expression of microRNAs
linked to the hemoglobinopathy status of the individuals affected. Thus, Dr. Driss proposes 3 aims to (i)
correlate miR-451 and Let-7i expression profiles with clinical blood analytical values and heme metabolism in
individuals with different sickle cell status; (ii) characterize the role of miR-451 and Let-7i regulation on P.
falciparum development in human erythrocytes in vitro and (iii) determine the role of miR-451 and Let-7i in
modulation of pathogenesis of malaria and hemoglobinopathies in a sickle cell mouse model. The overall goal
is to increase understanding of malaria severity in individuals with hemoglobinopathies and to identify
molecular biomar...
