Multiple myeloma (MM) is a plasma cells neoplasm which is often preceded by a preneoplastic condition called monoclonal gammopathy of unknown significance (MGUS). A protein called High-mobility group box-1 (HMGB-1) controls transcription and genomic stability. Both pro-and anti-tumor properties of HMGB1 have been described during tumor growth. The S100 protein family includes a protein known as psoriasin. Poorer prognosis and survival were linked to higher psoriasin expression in cancer patients. The goal of the current investigation was to compare the plasma levels of HMGB-1 and psoriasin in patients with MM and MGUS significance, as well as in a group of healthy controls. According to our research, patients with MGUS have higher HMGHB-1 con-centrations than healthy controls (846.7 +/- 287.6 pg/ml vs. 176.9 +/- 204.8 pg/ml for controls, p < 0.001). Similarly, we found a huge difference in HMGB-1 levels for MM patients with respect to controls (928.0 +/- 551.4 pg/ml vs. 176.9 +/- 204.8 pg/ml; p = 0.001). No difference was found as for the Psoriasin levels in the three groups considered. Additionally, we tried to evaluate the knowledge already present in the literature about putative mechanisms of action for these molecules in the onset and development of these disorders.

Abstract

Multiple myeloma (MM) is a plasma cells neoplasm which is often preceded by a preneoplastic condition called monoclonal gammopathy of unknown significance (MGUS). A protein called High-mobility group box-1 (HMGB-1) controls transcription and genomic stability. Both pro-and anti-tumor properties of HMGB1 have been described during tumor growth. The S100 protein family includes a protein known as psoriasin. Poorer prognosis and survival were linked to higher psoriasin expression in cancer patients. The goal of the current investigation was to compare the plasma levels of HMGB-1 and psoriasin in patients with MM and MGUS significance, as well as in a group of healthy controls. According to our research, patients with MGUS have higher HMGHB-1 con-centrations than healthy controls (846.7 +/- 287.6 pg/ml vs. 176.9 +/- 204.8 pg/ml for controls, p < 0.001). Similarly, we found a huge difference in HMGB-1 levels for MM patients with respect to controls (928.0 +/- 551.4 pg/ml vs. 176.9 +/- 204.8 pg/ml; p = 0.001). No difference was found as for the Psoriasin levels in the three groups considered. Additionally, we tried to evaluate the knowledge already present in the literature about putative mechanisms of action for these molecules in the onset and development of these disorders.
