The linear peptide is subjected to buffer at pH 7.5 where it undergoes esterification via a two-step mechanism

More research on the optimal preservation duration, temperature and unraveling the mechanism of CHS remain topics for further research

Once in the lumen of the tubule, the haemoproteins can be reabsorbed by the proximal tubules through the megalin/cubilin receptors complex,14 or even break down by releasing the haem group and free iron, which also have deleterious actions such as nitric oxide neutralisation, vasoconstriction and ischaemia.15 The reduced bioavailability of nitric oxide causes the deregulation of factors that control vascular tone, such as endothelin-1, thromboxane A2, tumour necrosis factor and isoprostanes.16,17 Hb and Mb are also powerful vasoconstrictors because they also react with nitric oxide, as described in diseases associated with intravascular haemolysis and rhabdomyolysis.1820 When present in the lumen of the tubule, both Mb and Hb can precipitate and bind to the Tamm-Horsfall protein and give rise to RBC casts, which cause intratubular obstruction in the distal nephron segments.21 This obstruction is assisted by the acidic pH found in urine, which increases the stability of the links between the haemoproteins and the Tamm-Horsfall protein.22,23 Inside the tubule cells, the haemoproteins dissociate by releasing globins and the haem group, which induces oxidative stress, cell death and the production of inflammatory cytokines and fibrosis, as discussed in more detail below

Genomic analysis using the Broad Institutes Connectivity Map showed that GHK-Cu can influence the expression of numerous human genes
