Abstract
S100B protein bridges chronic mucosal inflammation and colorectal cancer given its ability to activate NF-kappaB transcription via RAGE signalling and sequestrate pro-apoptotic wtp53. Being an S100B inhibitor, pentamidine antagonizes S100B-wtp53 interaction, restoring wtp53-mediated pro-apoptotic control in cancer cells in several types of tumours. The expression of S100B, pro-inflammatory molecules and wtp53 protein was evaluated in human biopsies deriving from controls, ulcerative colitis and colon cancer patients at baseline (a) and (b) following S100B targeting with niosomal PENtamidine VEhiculation (PENVE), to maximize drug permeabilization in the tissue. Cultured biopsies underwent immunoblot, EMSA, ELISA and biochemical assays for S100B and related pro-inflammatory/pro-apoptotic proteins. Exogenous S100B (0.005-5 μmol/L) alone, or in the presence of PENVE (0.005-5 μmol/L), was tested in control biopsies while PENVE (5 μmol/L) was evaluated on control, peritumoral, ulcerative colitis and colon cancer biopsies. Our data show that S100B level progressively increases in control, peritumoral, ulcerative colitis and colon cancer enabling a pro-inflammatory/angiogenic and antiapoptotic environment, featured by iNOS, VEGF and IL-6 up-regulation and wtp53 and Bax inhibition. PENVE inhibited S100B activity, reducing its capability to activate RAGE/phosphor-p38 MAPK/NF-kappaB and favouring its disengagement with wtp53. PENVE blocks S100B activity and rescues wtp53 expression determining pro-apoptotic control in colon cancer, suggesting pentamidine as a potential anticancer drug.

Abstract
TAG-1 is a 135,000 Mr axonal glycoprotein of the immunoglobulin superfamily that promotes axon extension in vitro. One distinguishing feature of TAG-1 is its transient expression on subsets of axons in the developing nervous system. To examine the mechanisms that regulate TAG-1, we have monitored the expression of this protein by developing central and peripheral neurons in vitro. TAG-1 was detected on the surface of a subset of E11 to E13 spinal cord neurons in vitro and was also released by these neurons. Expressions of TAG-1 on the cell surface was transient but it was possible to detect a released form of TAG-1 at all times in vitro. Spinal cord neurons isolated from older embryos did not express surface TAG-1 when they regenerated axons in vitro. Changes in the environment of spinal cord neurons did not alter the time course of TAG-1 expression, suggesting that regulation of the protein is cell autonomous. In contrast to these results with spinal cord neurons, surface expression of TAG-1 by DRG neurons persisted in vitro and adult DRG neurons re-expressed TAG-1 when grown in vitro. The cell surface and released forms of TAG-1 therefore appear to be regulated differently by central and peripheral neurons.
