Rats were divided into two groups and treated with daily intraperitoneal injections of saline (control) or the gamma-secretase inhibitor, Fli-06, for 2 days. Two-thirds of the rat livers were resected and rats were later euthanized at specific time points post-resection to analyze the remnant livers. Each group's liver/body weight ratio was calculated, and immunostaining and western blotting were used to determine the cell proliferation marker, PCNA and Ki-67 expression. Real-time PCR and western blotting were used to compare the mRNA expression of Notch homolog-1 ( ), hairy and enhancer of split-1 ( ), and vascular endothelial growth factor ( ), and the protein expression of NICD and HIF-1α, respectively. The liver/body weight ratios and number of Ki-67- and PCNA-positive cells were significantly lower in the experimental group than the control group, indicating lower levels of liver regeneration following the disruption of Notch signaling by Fli-06. The and mRNA levels and NICD and HIF-1α protein expression levels were all down-regulated by Fli-06 treatment. Notch-Hif-α signaling pathway activation plays an important role in liver regeneration, where it may contribute toward liver cell proliferation. Notch-Hif-α signaling pathway activation plays an important role in liver regeneration, where it may contribute toward liver cell proliferation. Cardiac diseases lead to heart failure (HF), but the progression can take several years. Using blood samples to monitor changes in the heart before clinical symptoms begin may help to improve patient management. Microarray data GSE42955 and GSE9128 were used as study datasets and GSE16499, GSE57338, and GSE59867 were used as validation groups. The "limma" package from R Language was used to identify differentially expressed genes. Functional enrichment analyses of gene ontology
