Adrenomedullin (AM) (1-52), human is a biologically active peptide composed of 52 amino acids, belonging to the calcitonin gene-related peptide superfamily, and exhibits significant vasodilatory effects[1-2]. Adrenomedullin (AM) (1-52), human acts as a regulatory factor for the growth of adult neural stem cells, influencing their proliferation rate and differentiation fate into neurons, astrocytes, and oligodendrocytes[3]. Adrenomedullin (AM) (1-52), human can modulate the proliferation process of cancer cells and promote angiogenesis, playing an important role in both cancer development and vascular formation during tissue repair[4].
In vitro, pretreatment of H9c2 cardiomyocytes with Adrenomedullin (AM) (1-52), human (10nM) for 30 minutes, followed by stimulation with palmitic acid (200μM) for 24 hours, significantly suppressed the protein expression of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6, while reducing intracellular reactive oxygen species levels and improving cell viability[5]. In hypoxically cultured bovine articular chondrocytes, pretreatment with Adrenomedullin (AM) (1-52), human (100nM) for 30 minutes, followed by stimulation with Fas ligand (20ng/mL) for 24 hours, significantly inhibited the activity of caspase-3 and caspase-8, while reducing the apoptosis rate[6].
In vivo, continuous infusion of Adrenomedullin (AM) (1-52), human (0.05mg/kg/h) via a carotid artery catheter in a C57/BL6 mouse model of lung injury induced by high tidal volume (17ml/kg) mechanical ventilation for 2 hours or moderate tidal volume (12ml/kg) ventilation for 6 hours, significantly reduced ventilator-induced increases in pulmonary vascular permeability and improved oxygenation function[7]. Continuous subcutaneous infusion of Adrenomedullin (AM) (1-52), human (0.05mg/kg/min) via an osmotic minipump in BALB/c mice treated with a single intraperitoneal injection of doxorubicin (20mg/kg) significantly improved the 14-day survival rate of mice exposed to high-dose doxorubicin and reduced serum lactate dehydrogenase levels[8].
