Rhodopsin is a G-protein coupled receptor (GPCR) that mediates vision under dim light. Upon light exposure, rhodopsin is phosphorylated at multiple serine and threonine sites at its carboxyl-terminus by rhodopsin kinase (GRK1). This, in turn, reduces its ability to activate the visual G-protein transducin. Binding of light-activated, ...

The kinase/RNase IRE1 is a key effector of the cellular response to endoplasmic reticulum stress. The RNase activity of IRE1 can be measured in cells or in the test tube. Here we describe a protocol for the
in vitro
cleavage and analysis of RNA substrates of IRE1. The method consists of the
in vitro
transcription, purification ...

Astrocytoma is an invasive carcinoma occurring in the nervous system and currently lacks effective treatment options. A deeper understanding of the mechanisms of tumorigenesis and tumor progression is needed in order to develop novel therapeutic strategies. Recent advances in
in vitro
culture systems have demonstrated that the use of ...

Multibeam scanning electron microscopy (multiSEM) provides a technical platform for seamless nano-to-mesoscale mapping of cells in human tissues and organs, which is a major new initiative of the U.S. National Institutes of Health. Such cross-length-scale imaging is expected to provide unprecedented understanding of relationships between cellular ...

Lipid droplets (LDs) are central organelles in maintaining lipid homeostasis. Defective LD growth often results in the development of metabolic disorders. LD fusion and growth mediated by cell death–inducing DNA fragmentation factor alpha (DFFA)-like effector (CIDE) family proteins are crucial for various biological processes including unilocular ...

Alveolar macrophages (AM) are tissue-resident macrophages that colonize the lung around birth and can self-maintain long-term in an adult organism without contribution of monocytes. AM are located in the pulmonary alveoli and can be harvested by washing the lungs using the method of bronchoalveolar lavage (BAL). Here, we compared different ...

The correct subcellular localization of proteins is vital for cellular function and the study of this process at the systems level will therefore enrich our understanding of the roles of proteins within the cell. Multiple methods are available for the study of protein subcellular localization, including fluorescence microscopy, organelle ...

The light dark paradigm is a common behavioral test used to screen a variety of pharmacological agents, including anxiogenics and anxiolytics. Although most often used in rodents, the light dark task has recently been adapted for use in zebrafish. However, a number of inconsistent findings have been reported for this species. Some have found ...

Obesity is an important health problem with a strong environmental component that is acquiring pandemic proportion. The high availability of caloric dense foods promotes overeating potentially causing obesity. Animal models are key to validate novel therapeutic strategies, but researchers must carefully select the appropriate model to draw the ...

Neuronal processes have an RNA composition that is distinct from the cell body. Therefore, to fully understand neuronal biology in health and disease we need to study both somas, dendrites and axons. Here we describe a detailed protocol of a newly refined method, Axon-seq, for RNA sequencing of axons (and dendrites) grown in isolation using single ...

Blumeria graminis
is a fungus that causes powdery mildews on grasses, such as barley. Investigations of this pathogen present many challenges due to its obligate biotrophic nature. This means that the fungus can only grow in the presence of a living host plant.
B. graminis
forms epiphytic mycelia on the plant surface and feeding ...

Symbiotic interactions between arbuscular mycorrhizal fungi (AMF) and plants are widespread among land plants and can be beneficial for both partners. The plant is provided with mineral nutrients such as nitrogen and phosphorous, whereas it provides carbon resources for the fungus in return. Due to the large economic and environmental impact, ...
