Abstract
In this review, we discuss the role of microtubule-associated protein 1B (MAP1B) and its phosphorylation in axonal development and regeneration in the central nervous system. MAP1B exhibits similar functions during axonal development and regeneration. MAP1B and phosphorylated MAP1B in neurons and axons maintain a dynamic balance between cytoskeletal components, and regulate the stability and interaction of microtubules and actin to promote axonal growth, neural connectivity and regeneration in the central nervous system.

Age-dependent modifications in vascular adhesion molecules and apoptosis after 48-h reperfusion in a rat global cerebral ischemia model. AGE (DORDRECHT, NETHERLANDS) 2014; 36:9703.

Abstract
Stroke is one of the leading causes of death and permanent disability in the elderly. However, most of the experimental studies on stroke are based on young animals, and we hypothesised that age can substantially affect the stroke response. The two-vessel occlusion model of global ischemia by occluding the common carotid arteries for 15 min at 40 mmHg of blood pressure was carried out in 3- and 18-month-old male Sprague-Dawley rats. The adhesion molecules E- and P-selectin, cell adhesion molecules (CAMs), both intercellular (ICAM-1) and vascular (VCAM-1), as well as glial fibrillary acidic protein (GFAP), and cleaved caspase-3 were measured at 48 h after ischemia in the cerebral cortex and hippocampus using Western blot, qPCR and immunofluorescence techniques. Diametric expression of GFAP and a different morphological pattern of caspase-3 labelling, although no changes in the cell number, were observed in the neurons of young and old animals. Expression of E-selectin and CAMs was also modified in an age- and ischemia/reperfusion-dependent manner. The hippocampus and cerebral cortex had similar response patterns for most of the markers studied. Our data suggest that old and young animals present different time-courses of neuroinflammation and apoptosis after ischemic damage. On the other hand, these results suggest that neuroinflammation is dependent on age rather than on the different vulnerability described for the hippocampus and cerebral cortex. These differences should be taken into account in searching for therapeutic targets.

Abstract
Based on about a decade of technical developments in analysing the human proteome with antibody microarrays and experience in performing such analyses, now there are the means at hand for detailed and simultaneously global investigations of this kind. Many technical aspects have been dealt with of both the microarray format itself - such as overcoming kinetic and mass transport limitations and thus achieving accurate measurements - and ancillary processes - such as extraction procedures that provide good protein solubilisation, produce reproducible yields and preserve the native protein conformation as much as possible. The overall analysis process is robust and reproducible, highly sensitive down to the level of single-molecule detection and permits an analysis of several parameters on many molecules at a time. While the study of body liquids is widely applied, analyses of tissue proteomes are still scarce. However, conditions do exist to perform the latter at a quality level that meets the standards for clinical applications. This review highlights methodological aspects relevant for a biomedically useful analysis of cellular samples and discusses the potential of such studies, in particular, in view of personalised medicine approaches.

Apoptosis-related proteins are potential markers of neonatal hypoxic-ischemic encephalopathy (HIE) injury. Neurosci Lett 2014; 558:143-8. [PMID: 24269372 DOI: 10.1016/j.neulet.2013.11.019] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2013] [Revised: 11/11/2013] [Accepted: 11/13/2013] [Indexed: 02/05/2023]
Abstract
Neonatal hypoxic-ischemic encephalopathy (HIE) causes high mortality and long-term morbidity rates. The magnitude of the neuronal damage depends on the duration and severity of the initial insult combined with the deleterious effects of reperfusion and apoptosis. Currently, a diagnosis of HIE is based largely on the neurological and histological findings. Therefore, the aim of this study was to identify apoptosis-related proteins that might serve as potential markers of HIE injury. As an initial step toward reaching this objective, we analyzed changes in protein levels in an in vitro model of hypoxia using antibody arrays, and we have identified changes in the expression level of two proteins involved in apoptosis, Smac-DIABLO and cathepsin D. We obtained brain sections from eight neonatal HIE patients and performed histological staining, TUNEL assays and Smac-DIABLO and cathepsin D immunolocalization. Our results revealed a high number of TUNEL-positive cells, including neurons, astrocytes and ependymal cells, in the various regions that were analyzed. Interestingly, many of the areas that were positive for TUNEL staining did not appear to be damaged in the histological evaluation. In addition, using immunostaining, we found that Smac-DIABLO and cathepsin D had the same regional distribution pattern. Taken together, these findings indicate that these two proteins could serve as markers to identify injured regions that might not to be detectable using histological observations alone.
