BACKGROUND: Liver regeneration (LR) after 2/3 partial hepatectomy (PH) is one of the most studied models of cell, organ, and tissue regeneration. Although the transcriptional profile analysis of regenerating liver has been carried out by many reserachers, the dynamic protein expression profile during LR ...
BACKGROUND: The hippocampal CA3 area contains large amounts of vesicular zinc in the mossy fiber terminals which is released during synaptic activity, depending on presynaptic calcium. Another characteristic of these synapses is the presynaptic localization of high concentrations of group II metabotropic...
BACKGROUND: Tuberculosis (TB) is a respiratory tract disease caused by Mycobacterium tuberculosis infection. M. tuberculosis exploits immune privilege to grow and divide in pleural macrophages. Fibrates are associated with the immune response and control lipid metabolism through glycolysis with β-oxidat...
Background: An adaptive mechanism in plant roots is initiated in the event of nitrogen and potassium deficiency, and it facilitates the active uptake of these elements in order to ensure plant growth and survival in stress conditions. Signaling and transduction of signals in response to changing nitrogen...
Durante o desenvolvimento do sistema nervoso, as células têm a tarefa de proliferar, migrar, diferenciar, morrer ou amadurecer de modo altamente preciso para formar estruturas complexas. Tal precisão é alcançada em decorrência da interação perfeita entre as células que se comunicam por meio de m...
Los esfingolípidos, como la ceramida (Cer), la ceramida-1-fosfato (C-1-P), la esfingosina (Sph) y la esfingosina-1-fosfato (S-1P) estan relacionados con la señalización intracelular en procesos como crecimiento celular, movilización intracelular de Ca+2 y apoptósis. En este trabajo se evaluó el efe...
El tejido sanguíneo está compuesto en un 45% aproximadamente por células y derivados de éstas, con una vida media que oscila entre 120 días para los eritrocitos y alrededor de 3 años para ciertos tipos de linfocitos. Esta pérdida es compensada gracias a la actividad del sistema hematopoyético y a...
