Proteomic analysis of the regenerating liver following 2/3 partial hepatectomy in rats

Biol. Res; 47 (), 2014
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 ...

Activation of group II metabotropic glutamate receptors blocks zinc release from hippocampal mossy fibers

Biol. Res; 47 (), 2014
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...

Normalization of the levels of inflammatory molecules in Mycobacterium smegmatis-infected U937 cells by fibrate pretreatment

Biol. Res; 47 (), 2014
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...

Chromosomal localization of selected SCARs converted from new RAPD, ISSR and R-ISSR markers linked to rye (Secale cereale L. ) tolerance to nutrient deprivation stress identified using bulk segregant analysis

Electron. j. biotechnol; 16 (5), 2013
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...

Mecanismos de ação da bradicinina na diferenciação neural in vitro

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...

Efecto de esfingolípidos y Agelosina B en la movilización de Ca2+ y la señalización celular en células de cáncer de mama (MCF-7) y su relación con la apoptosis

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...

Células madre hematopoyéticas, generalidades y vías implicadas en sus mecanismos de auto-renovación

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...
