A Thermodynamic Model for Receptor Clustering [PDF]
Intracellular signaling often arises from ligand-induced oligomerization of cell surface receptors. This oligomerization or clustering process is fundamentally a cooperative behavior between near-neighbor receptor molecules; the properties of this cooperative process clearly affects the signal transduction.

High- and low-conductance NMDA receptors are present in layer 4 spiny stellate and layer 2/3 pyramidal neurons of mouse barrel cortex [PDF]
NMDA receptors are ion channels activated by the neurotransmitter glutamate in the mammalian brain and are important in synaptic function and plasticity, but are also found in extrasynaptic locations and influence neuronal excitability. There are different NMDA receptor subtypes which differ in their single-channel conductance.

The quest for the best target genes for RNAi‐mediated pest control
A major challenge for RNAi mediated pest control is the identification of the most effective RNAi target genes from the pool of ~37% of all genes that are essential. Effective RNAi target genes are predominantly highly conserved genes serving basic cellular functions such as protein degradation.

Activation of Drosophila hemocyte motility by the ecdysone hormone
Summary Drosophila hemocytes compose the cellular arm of the fly's innate immune system. Plasmatocytes, putative homologues to mammalian macrophages, represent ∼95% of the migratory hemocyte population in circulation and are responsible for the ...

Cargo binding promotes KDEL receptor clustering at the mammalian cell surface [PDF]
Transmembrane receptor clustering is a ubiquitous phenomenon in pro- and eukaryotic cells to physically sense receptor/ligand interactions and subsequently translate an exogenous signal into a cellular response. Despite that receptor cluster formation has been described for a wide variety of receptors, ranging from chemotactic receptors in bacteria to ...

Autophagy‐related genes exert their effects not only by regulating autophagy but also by modulating apoptosis. This study provided evidence for anti‐apoptotic effects of Atg3 and Atg5 and pro‐apoptotic effects of Atg12 in the posterior silk gland.

Abstract Organisms inhabiting highly seasonal environments must cope with a wide range of environmentally induced challenges. Many seasonal challenges require extensive physiological modification to survive. In winter, to survive extreme cold and limited resources, insects commonly enter diapause, which is an endogenously derived dormant state ...

DNA affects ligand binding of the ecdysone receptor of Drosophila melanogaster [PDF]
The heterodimers of all three ecdysone receptor (EcR) isoforms with Ultraspiracle (Usp), the invertebrate orthologue of RXR, bind Ponasterone A with the same affinity in the absence of DNA. Ligand binding is stimulated by ecdysone response elements (EcREs) to different degrees depending on the receptor isoform, the heterodimerization partner, and the ...

Method for Screening Ecdysone-Inducible Stable Cell Lines
Ecdysone-inducible systems are useful tools to study the function of various genes in different types of mammalian cells. However, it is technically difficult to establish stable cell lines.
