Abstract: Heart failure (HF) is the fastest-growing cardiovascular condition worldwide. The
immune system may play a role in the development of HF since this condition is associated with
elevated pro-inflammatory cytokine levels. HF is a life-threatening disease, and there is an increasing
demand for diagnostic biomarkers, prognostic factors, and therapeutic agents that can
help treat it. Galectin-1 (Gal-1) is the prototype galectin of the lectin family. Multiple signal
transduction pathways are regulated by Ras proteins, which act as a molecular switch in cells.
Gal-1 regulates T and B cell activation, differentiation, and survival. Gal-1 has been linked to inflammation.
Activated T cells produce Gal-1 through an autocrine apoptotic mechanism involving
MEK1/ERK and p38 MAPK. In the cardiovascular system, atherosclerosis is facilitated by
Gal-1. Heart disease, myocardial infarction, hypertension, and stroke can be caused by atherosclerotic
plaque. HF and heart hypertrophy are caused by decreased cardiac L-type Ca2+ channel
activity. Deregulation of Gal-1 and CaV1.2 in pathological cardiac hypertrophy suggests a possible
target for anti-hypertrophic therapy. Rat hypertrophic cardiomyocytes express Gal-1 and
CaV1.2 channels simultaneously. It has been reported that diastolic dysfunction (DD) is associated
with elevated Gal-1 levels. The high Gal-1 level in subjects led to the lowest cumulative survival
as a composite endpoint. Incidences of HF, DD, and serum Gal-1 levels correlated significantly.
The ejection fraction was negatively correlated with Gal-1 and CRP concentrations.
Based on two different approaches in mice and humans, Gal-1 was identified as a potential mediator
of HF.
