Travel and the emergence of high-level drug resistance in Plasmodium falciparum in southwest Uganda: results from a population-based study

open access: yesMalaria Journal, 2017
Background The I164L mutation on the dhfr gene confers high level resistance to sulfadoxine–pyrimethamine (SP) but it is rare in Africa except in a cluster of reports where prevalence >10% in highland areas of southwest Uganda and eastern Rwanda.

Oxidative degradation of dihydrofolate reductase increases CD38-mediated ferroptosis susceptibility

open access: yesCell Death and Disease, 2022
High expression of CD38 in tissues is a characteristic of aging, resulting in a decline in nicotinamide adenine dinucleotide (NAD) and increasing cellular reactive oxygen species (ROS).

The effect of Point Mutations in Dihydrofolate reductase genes and Multidrug resistance gene 1-86 on treatment of falciparum malaria in Sudan

open access: yesJournal of Infection in Developing Countries, 2009
Background: One of the major problems to the treatment of malaria is the emergence and spread of parasite resistant to antimalarial drugs. Due to increased chloroquine (CQ) resistance, the antifolate combinations are becoming important in the ...

Cycloguanil and Analogues Potently Target DHFR in Cancer Cells to Elicit Anti-Cancer Activity

open access: yesMetabolites, 2023
Dihydrofolate reductase (DHFR) is an established anti-cancer drug target whose inhibition disrupts folate metabolism and STAT3-dependent gene expression. Cycloguanil was proposed as a DHFR inhibitor in the 1950s and is the active metabolite of clinically

Prevalence of the dhfr and dhps Mutations among Pregnant Women in Rural Burkina Faso Five Years after the Introduction of Intermittent Preventive Treatment with Sulfadoxine-Pyrimethamine

open access: yesPLoS ONE, 2015
Background The emergence and spread of drug resistance represents one of the biggest challenges for malaria control in endemic regions. Sulfadoxine-pyrimethamine (SP) is currently deployed as intermittent preventive treatment in pregnancy (IPTp) to ...
