GSTM1 Gene, Diet, and Kidney Disease: Implication for Precision Medicine?: Recent Advances in Hypertension

Area of Science:

• Nephrology
• Genetics
• Nutritional Science

Background:

• Chronic kidney disease (CKD) affects ≈14% of US adults, often progressing to end-stage kidney disease despite standard therapies like ACE inhibitors or ARBs.
• Oxidative stress is a key factor in CKD progression.
• The glutathione-S-transferase μ-1 (GSTM1) null genotype (GSTM1(0)) is associated with reduced enzyme activity and increased oxidative stress.

Purpose of the Study:

• To review the role of GSTM1 deficiency in hypertension and kidney disease.
• To examine the impact of GSTM1 genotype on the protective effects of cruciferous vegetables against kidney injury.
• To illustrate the significance of gene-environment interactions in kidney disease.

Main Methods:

• Review of recent human and animal studies.
• Analysis of the relationship between GSTM1 genotype, oxidative stress, and kidney disease.
• Investigation of the Nrf2 pathway and the role of sulforaphane from cruciferous vegetables.

Main Results:

• GSTM1 deficiency is implicated in hypertension and kidney disease progression.
• Reduced GSTM1 activity correlates with increased oxidative stress.
• Sulforaphane, derived from cruciferous vegetables, activates Nrf2, offering potential protection against oxidative damage.

Conclusions:

• GSTM1 genotype influences kidney disease susceptibility and progression.
• Gene-environment interactions, particularly involving diet (cruciferous vegetables), play a crucial role in kidney health.
• Targeted precision medicine strategies may leverage these interactions for novel CKD treatments.
