Uremic toxins such as spermine are actively transported into the kidneys via organic ion transporters (especially OAT3). Increased levels of uremic toxins can stimulate the production of reactive oxygen species. This seems to be mediated by the direct binding or inhibition by uremic toxins of the enzyme NADPH oxidase (especially NOX4 which is abundant in the kidneys and heart) (A7868). Reactive oxygen species can induce several different DNA methyltransferases (DNMTs) which are involved in the silencing of a protein known as KLOTHO. KLOTHO has been identified as having important roles in anti-aging, mineral metabolism, and vitamin D metabolism. A number of studies have indicated that KLOTHO mRNA and protein levels are reduced during acute or chronic kidney diseases in response to high local levels of reactive oxygen species (A7869). Spermine is derived from spermidine by spermine synthase. Spermine is a polyamine, a small organic cations that is absolutely required for eukaryotic cell growth. Spermine, is normally found in millimolar concentrations in the nucleus. Spermine functions directly as a free radical scavenger, and forms a variety of adducts that prevent oxidative damage to DNA. Oxidative damage to DNA by reactive oxygen species is a continual problem that cells must guard against to survive. Hence, spermine is a major natural intracellular compound capable of protecting DNA from free radical attack. Spermine is also implicated in the regulation of gene expression, the stabilization of chromatin, and the prevention of endonuclease-mediated DNA fragmentation.

As a uremic toxin, this compound can cause uremic syndrome. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Abnormal bleeding, such as bleeding spontaneously or profusely from a very minor injury can also occur. Heart problems, such as an irregular heartbeat, inflammation in the sac that surrounds the heart (pericarditis), and increased pressure on the heart can be seen in patients with uremic syndrome. Shortness of breath from fluid buildup in the space between the lungs and the chest wall (pleural effusion) can also be present.
