Insights into Alkaline Phosphatase Anti-Inflammatory Mechanisms.

Background: The endogenous ecto-enzyme and exogenously administered alkaline phosphatase (ALP) have been evidenced to significantly attenuate inflammatory conditions, including Toll-like receptor 4 (TLR4)-related signaling and cytokine overexpression, barrier tissue dysfunction and oxidative stress, and metabolic syndrome and insulin resistance, in experimental models of colitis, liver failure, and renal and cardiac ischemia-reperfusion injury. This suggests multiple mechanisms of ALP anti-inflammatory action that remain to be fully elucidated.

Methods: Recent studies have contributed to a deeper comprehension of the role played by ALP in immune metabolism.

LPS-Dephosphorylating Alkaline Phosphatase of PhoA Family Divergent from the Multiple Homologues of spp.

A highly active alkaline phosphatase (ALP) of the protein structural family PhoA, from a mussel gut-associated strain of the marine bacterium KMM 296 (CmAP), was found to effectively dephosphorylate lipopolysaccharides (LPS). Therefore, the aim of this work was to perform a comprehensive bioinformatics analysis of the structure, and to suggest the physiological role of this enzyme in marine bacteria of the genus . A scrutiny of the CmAP-like sequences in 36 available genomes revealed nine homologues intrinsic to the subspecies , whereas PhoA of a distant relative JO1 carried an inactive mutation.

[Possible mechanism of the selective action of the inhibitors of glycolysis in the endothelial cells and the human carcinoma cells in the culture].

It is known that the production of energy and synthesis of macromolecules in cancer cells depend on the glucose metabolism to a greater extent than in non-tumor. In this paper we carry out a comparative study of the effectiveness of the two modifiers glycolysis 2 - D-deoxyglucose (2-DG) and dichloroacetate (DCA) in the induction of the cell death, changes in the cell cycle progression and in the alteration of the intracellular ROS levels in endothelial cells (line ECV304) and human carcinoma cells (line HeLa G-63) in order to identify cause-effect relations between these events. It has been shown that inhibition of the various stages of the glycolysis result in blocking cells in C2/M phase of the cell cycle and the induction of the cell death.

[Possibilities of epigenetic anti-tumor therapy in in-vitro models].

Research during the past decade has shown that epigenetic events have a key role in carcinogenesis and tumour progression. Histone deacetylase inhibitors (HDACi) comprise structurally diverse compounds that are a group of targeted epigenetic anticancer agents. Here we explored the in vitro efficacy of HDACi such as sodium butyrate (BuNa), valproic acid (VaNa) and several novel HDAC inhibitors for the treatment of cancer.
