Mesenchymal stem cells (MSCs) are an appealing potential therapy for vascular diseases; however, many challenges remain in their clinical translation. While the use of biochemical, pharmacological, and substrate-mediated treatments to condition MSCs has been subjected to intense investigation, there has been far less exploration of using these treatments in combination with applied mechanical force for conditioning MSCs toward vascular phenotypes. This review summarizes the current understanding of the use of applied mechanical forces to differentiate MSCs into vascular cells and enhance their therapeutic potential for cardiovascular disease...

Varenicline is a synthetic chemical substance produced from the alkaloid cytisine, used for smoking treatment, which acts as a partial agonist for α4β2 and α3β4 nicotinic cholinergic receptors and as a total agonist for α7 receptor. While there are studies regarding varenicline's non-smoking-related effects, as in treatment for drug dependence, there are no studies in the literature evaluating the long-term toxicity of varenicline through a physiological approach. Thus, the aim of this study was to evaluate possible toxicity through hematological, biochemical and anatomopathological parameters of prolonged exposure (30 days) to varenicline in rats...

Glucocorticoids are associated with lipid metabolism and their abnormal expression has an important function in the development of metabolic syndrome. The 11β‑hydroxysteroid dehydrogenase type 1 (11β‑HSD1) is a metabolic enzyme of glucocorticoids and may be a potential drug target for the treatment of metabolic syndrome. However, the association between the systemic expression of 11β‑HSD1 and metabolic syndrome remains to be elucidated. The present study used a cytomegalovirus promoter to obtain mice that systemically overexpressed the 11β‑HSD1 gene...

Nitika, Andrew W Truman
Heat shock protein 70 (Hsp70) is an evolutionarily well-conserved molecular chaperone involved in several cellular processes such as folding of proteins, modulating protein-protein interactions, and transport of proteins across the membrane. Binding partners of Hsp70 (known as "clients") are identified on an individual basis as researchers discover their particular protein of interest binds to Hsp70. A full complement of Hsp70 interactors under multiple stress conditions remains to be determined. A promising approach to characterizing the Hsp70 "interactome" is the use of protein epitope tagging and then affinity purification followed by mass spectrometry (AP-MS/MS)...

Full-length immunoglobulins (Igs) are widely considered difficult to crystallize because of their large size, N-linked glycosylation, and flexible hinge region. However, numerous cases of intracellular Ig crystallization are reported in plasma cell dyscrasias. What makes some Ig clones more prone to crystallize during biosynthesis as well as the biochemical and cell biological requirements for this cryptic event are poorly understood. To investigate the underlying process of intracellular Ig crystallization we searched for model IgGs that can induce crystalline inclusions during recombinant overexpression...

Procaspase-2 phosphorylation at several residues prevents its activation and blocks apoptosis. This process involves procaspase-2 phosphorylation at S164 and its binding to the scaffolding protein 14-3-3. However, bioinformatics analysis has suggested that a second phosphoserine-containing motif may also be required for 14-3-3 binding. In this study, we show that human procaspase-2 interaction with 14-3-3 is governed by phosphorylation at both S139 and S164. Using biochemical and biophysical approaches, we show that doubly phosphorylated procaspase-2 and 14-3-3 form an equimolar complex with a dissociation constant in the nanomolar range...
