Keloid disease (KD) is a fibroproliferative disorder characterised partly by an altered extracellular matrix (ECM) profile. In fetal scarring, hyaluronic acid (HA) expression is increased, but is reduced in KD tissue compared with normal skin (NS). The expression of Hyaluronan Synthase (HAS) and hyaluronidase (HYAL) in KD and NS tissue were investigated for the first time using a range of techniques. Hyaluronan synthase and HYAL mRNA expression were significantly increased in NS tissue compared with KD tissue (P < 0.05). Immunohistological analysis of tissue indicated an accumulation of HAS and HYAL protein expression in KD compared with NS due to the thicker epidermis. No differences were observed in mRNA or protein expression in KD and NS fibroblasts. Reduced expression of HAS and HYAL may alter HA synthesis, degradation and accumulation in KD. Better understanding of the role of HA in KD may lead to novel therapeutic approaches to address the resulting ECM imbalance.
