Plzf
Gene Ameliorates Metabolic and Cardiac Traits in the Spontaneously Hypertensive Rat. Hypertension 2017; 69:1084-1091. [DOI: 10.1161/hypertensionaha.116.08798] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2016] [Revised: 12/06/2016] [Accepted: 03/09/2017] [Indexed: 12/20/2022]
Abstract
The spontaneously hypertensive rat (SHR), one of the most widely used model of essential hypertension, is predisposed to left ventricular hypertrophy, myocardial fibrosis, and metabolic disturbances. Recently, quantitative trait loci influencing blood pressure, left ventricular mass, and heart interstitial fibrosis were genetically isolated within a minimal congenic subline that contains only 7 genes, including mutant
Plzf
(promyelocytic leukemia zinc finger) candidate gene. To identify
Plzf
as a quantitative trait gene, we targeted
Plzf
in the SHR using the transcription activator-like effector nuclease technique and obtained SHR line harboring targeted
Plzf
gene with a premature stop codon. Because the
Plzf
targeted allele is semilethal, morphologically normal heterozygous rats were used for metabolic and hemodynamic analyses. SHR-
Plzf
+/−
heterozygotes versus SHR wild-type controls exhibited reduced body weight and relative weight of epididymal fat, lower serum and liver triglycerides and cholesterol, and better glucose tolerance. In addition, SHR-
Plzf
+/−
rats exhibited significantly increased sensitivity of adipose and muscle tissue to insulin action when compared with wild-type controls. Blood pressure was comparable in SHR versus SHR-
Plzf
+/−
; however, there was significant amelioration of cardiomyocyte hypertrophy and cardiac fibrosis in SHR-
Plzf
+/−
rats. Gene expression profiles in the liver and expression of selected genes in the heart revealed differentially expressed genes that play a role in metabolic pathways, PPAR (peroxisome proliferator-activated receptor) signaling, and cell cycle regulation. These results provide evidence for an important role of
Plzf
in regulation of metabolic and cardiac traits in the rat and suggest a cross talk between cell cycle regulators, metabolism, cardiac hypertrophy, and fibrosis.
