Intercellular Arc Signaling Regulates Vasodilation

Symplastic intercellular connectivity regulates lateral root patterning.

Cell-to-cell communication coordinates the behavior of individual cells to establish organ patterning and development. Although mobile signals are known to be important in lateral root development, the role of plasmodesmata (PD)-mediated transport in this process has not been investigated. Here, we show that changes in symplastic connectivity accompany and regulate lateral root organogenesis in...

The Arabidopsis floral homeotic gene APETALA3 differentially regulates intercellular signaling required for petal and stamen development.

Cell-cell signaling is crucial for the coordination of cell division and differentiation during plant organogenesis. We have developed a novel mosaic analysis method for Arabidopsis, based on the maize Ac/Ds transposable element system, to assess the requirements of individual genes in intercellular signaling. Using this strategy, we have shown that the floral homeotic APETALA3 (AP3) gene has d...

miR-320 regulates inflammation in EAE through interference with TGF-β signaling pathway

Background: MicroRNAs are small noncoding RNAs that regulate gene expression and involve in many cellular and physiological mechanisems. Recent studies have revealed that dysregulation of microRNAs might contribute to autoimmune disorders such as multiple sclerosis. Based on these findings, we examined the potential role of miR-320 isoforms, miR-320-3p and miR-320-5p, in the context of autoimmu...

Endoplasmic reticulum stress regulates inflammation in adipocyte of obese rats via toll-like receptors 4 signaling

Objective(s): To explore whether endoplasmic reticulum (ER) stress regulates inflammation in adipose tissue of obese rats via TLR4 signaling. Materials and Methods: Sprague Dawley rats were randomly divided into four groups, and body weight, food intake, and free fatty acids (FFA) were measured. Real-time PCR and Western blot were used to determine mRNA or protein expression of TLR4, TRAF6, IKK...
