Abstract:
This review presents an overview of the regulation, function, disease-relevance and pharmacological regulation of the critical endothelial transcription factors KLF2/4 in vasculature. The regulatory mechanisms of KLF2/4 expression and activity in vascular endothelium in response to hemodynamic forces and biochemical stimuli are depicted. The functional effects mediated by direct or indirect target genes of KLF2/4 in endothelial cells are systematically summarized. The contributory roles that dysregulated KLF2/4 play in relevant cardiovascular pathologies, such as atherosclerotic vascular lesions, pulmonary arterial hypertension and vascular complications of diabetes were reviewed. Moreover, this review also discusses the pharmacological regulation of KLF2/4 by drugs used in clinics and therapeutic possibility by directly targeting these two transcription factors for treating atherosclerotic cardiovascular diseases. Finally, prospective opinions on the gaps in disclosing novel vascular function mediated by KLF2/4 and future research needs are expressed.

Background:
- Endothelial transcription factors Kruppel-like factor 2 (KLF2) and Kruppel-like factor 4 (KLF4) are crucial regulators of vascular homeostasis.
- Their expression and activity are influenced by hemodynamic forces and biochemical signals within the endothelium.
Purpose of the Study:
- To provide a comprehensive overview of KLF2/4 regulation, function, and disease relevance in the vasculature.
- To explore the pharmacological modulation of KLF2/4 and their therapeutic potential in cardiovascular diseases.
Main Methods:
- Systematic review of existing literature on KLF2/4.
- Analysis of regulatory mechanisms, functional effects via target genes, and roles in pathologies.
- Discussion of pharmacological interventions and therapeutic targeting.
Main Results:
- KLF2/4 are key mediators of endothelial responses to physiological stimuli.
- Dysregulation of KLF2/4 is implicated in atherosclerosis, pulmonary arterial hypertension, and diabetic vasculopathy.
- Pharmacological agents can modulate KLF2/4 activity, suggesting therapeutic avenues.
Conclusions:
- KLF2/4 are critical targets for understanding and treating vascular diseases.
- Further research is needed to fully elucidate novel vascular functions and optimize therapeutic strategies targeting KLF2/4.
