“Vesicular stomatitis virus (VSV) is potent and a highly promising agent for the treatment of cancer. However, translation

of VSV oncolytic virotherapy into the clinic is being hindered by its inherent neurotoxicity. It has been demonstrated that selected picornaviral internal ribosome entry site (IRES) elements possess restricted activity in neuronal tissues. We therefore sought to determine whether the picornavirus IRES could be engineered into VSV to attenuate its neuropathogenicity. We have used IRES elements from human rhinovirus type 2 (HRV2) and foot-and-mouth disease virus (FMDV) to control the translation of the matrix gene (M), which plays a major role in VSV virulence. In vitro studies revealed slowed growth kinetics of IRES-controlled VSVs in most of the cell lines tested. However, in vivo studies explicitly demonstrated that IRES elements of HRV2

and FMDV severely attenuated the neurovirulence of VSV without perturbing its oncolytic potency.”
“Thermolysin Rapamycin in vitro and other secreted broad-specificity proteases, such as subtilisin or alpha-lytic protease, are produced as pre-pro-proteins that stay at least partially unfolded while in the cytosol. After secretion, the pro-proteases fold to their active conformations in a process that includes the autolytic removal of the pro-peptide. We review the life cycle of the thermolysin-like protease from Bacillus stearothermophilus in light of the calcium dependent stability and instability of the N-terminal domain. The protease binds calcium ions in the regions

that are involved in the autolytic maturation process. It is generally assumed that the calcium ions contribute to the extreme stability of the protease, but buy CHIR-99021 experimental evidence for TLP-ste indicates that at least one of the calcium ions plays a regulatory role. We hypothesize that this calcium ion plays an important role as a switch that modulates the protease between stable and unstable states as appropriate to the biological need.”
