Identifying Novel Signaling Pathways: An Exercise Scientists Guide to Phosphoproteomics.

We propose that phosphoproteomic-based studies will radically advance our knowledge about exercise regulated signaling events. However, these studies utilize cutting-edge technologies that can be difficult for non-specialists to understand. Hence, this review is intended to help non-specialists: 1) understand the fundamental technologies behind phosphoproteomic analysis and 2) employ various bioinformatic tools that can be used to interrogate phosphoproteomic datasets.

Notch inhibitors and their role in the treatment of triple negative breast cancer: promises and failures.

Notch signaling is a highly evolutionarily conserved cell-to-cell communication system that is involved in a number of pivotal cellular processes, such as development, stem cell maintenance, cell fate specification, differentiation, proliferation, and death. Much progress has been made in understanding Notch signaling. This review will focus on the role of canonical Notch signaling pathway in breast cancer cause and progressing.

MiR-155 regulates lymphoma cell proliferation and apoptosis through targeting SOCS3/JAK-STAT3 signaling pathway.

Janus kinase (JAK)- signal transducer and activator of transcription (STAT) signaling pathway participates in regulating cell proliferation, differentiation, and apoptosis, and related to lymphoma. Suppressors of cytokine signaling 3 (SOCS3) is a negative regulator of the JAK-STAT signaling pathway. SOCS3 reduction and miR-155 up-regulation are associated with lymphoma pathogenesis. Bioinformatics analysis showed the complementary binding site between miR-155 and SOCS3. This study aimed to investigate the r...

Cell Polarity and Notch Signaling: Linked by the E3 Ubiquitin Ligase Neuralized?

Notch is a mechanosensitive receptor that requires direct cell-cell contact for its activation. Both the strength and the range of notch signaling depend on the size and geometry of the contact sites between cells. These properties of cell-cell contacts in turn depend on cell shape and polarity. At the molecular level, the E3 ubiquitin ligase Neuralized (Neur) links receptor activation with epithelial cell remodeling. Neur regulates the endocytosis of the Notch ligand Delta (Dl), hence Notch activation. It ...

Control of B-1a cell development by instructive BCR signaling.

B-1a cells remain one of the most enigmatic lymphocyte subsets. In this review, we discuss recent advances in our understanding of the development of these cells and their regulation by the transcription factors Bhlhe41 and Arid3a as well as by the RNA-binding protein Lin28b. A large body of literature supports an instructive role of BCR signaling in B-1a cell development and lineage commitment, which is initiated only after signaling from an autoreactive BCR. While both fetal and adult hematopoiesis can ge...

The Role of PAR2 in TGF-β1-Induced ERK Activation and Cell Motility.

Recently, the expression of proteinase-activated receptor 2 (PAR2) has been shown to be essential for activin receptor-like kinase 5 (ALK5)/SMAD-mediated signaling and cell migration by transforming growth factor (TGF)-β1. However, it is not known whether activation of non-SMAD TGF-β signaling (e.g., RAS-RAF-MEK-extracellular signal-regulated kinase (ERK) signaling) is required for cell migration and whether it is also dependent on PAR2.

Stereotypical architecture of the stem cell niche is spatiotemporally established by miR-125-dependent coordination of Notch and steroid signaling.

Stem cell niches act as signaling platforms that regulate stem cell self-renewal and sustain stem cells throughout life; however, the specific developmental events controlling their assembly are not well understood. Here we show that during Drosophila ovarian germline stem cell niche formation, the status of Notch signaling in the cell can be reprogrammed. This is controlled via steroid-induced miR-125, which targets a negative regulator of Notch signaling, Tom. Thus, miR-125 acts as a spatiotemporal coordi...

Once upon a time ...A special issue for the 10th anniversary of the Journal of Cell Communication and Signaling.

Wnt Ligands as a Part of the Stem Cell Niche in the Intestine and the Liver.

The term "Wnt signaling" does not refer to one uniform signal transduction cascade. Instead, it describes the multiple discrete signals elicited by Wnt ligands following their interaction with distinct receptor complexes. The interaction of stem cells with niche cells is coordinated by the involvement of different signaling pathways, including Wnt signaling. The stem cell populations are highly sensitive to modulation of Wnt pathway activity. Wnt signaling is of paramount importance for stem cell self-renew...

The nuclear pore complex: a strategic platform for regulating cell signaling.

I II. III. IV. V. References SUMMARY: Nuclear pore complexes (NPCs) are fundamental components of the eukaryotic cell. They perforate the nuclear envelope and serve as highly selective transport gates that enable bi-directional macromolecule exchange between the nucleus and cytoplasm. Recent studies illustrate that the NPC is not a static structural channel but a flexible environment and strategic player during nuclear signaling. The constitutional and conformational dynamics of the NPC allow it to tailor n...

In this review, we mainly presented the recent work on the quantitative charact...

A temporal examination of calcium signaling in cancer- from tumorigenesis, to immune evasion, and metastasis.

Although the study of calcium (Ca) is classically associated with excitable cells such as myocytes or neurons, the ubiquity of this essential element in all cellular processes has led to interest in other cell types. The importance of Ca to apoptosis, cell signaling, and immune activation is of special import in cancer.

Transient acceleration of epidermal growth factor receptor dynamics produces higher-order signaling clusters.

Cell signaling depends on spatiotemporally regulated molecular interactions. Although the movements of signaling proteins have been analyzed with various technologies, how spatial dynamics influence the molecular interactions that transduce signals is unclear. Here, we developed a single-molecule method to analyze the spatiotemporal coupling between motility, clustering, and signaling. The analysis was performed with the epidermal growth factor receptor (EGFR), which triggers signaling through its dimerizat...

SPRING: a kinetic interface for visualizing high dimensional single-cell expression data.

Single-cell gene expression profiling technologies can map the cell states in a tissue or organism. As these technologies become more common, there is a need for computational tools to explore the data they produce. In particular, visualizing continuous gene expression topologies can be improved, since current tools tend to fragment gene expression continua or capture only limited features of complex population topologies.

Beyond the bulk: disclosing the life of single microbial cells.

Microbial single cell analysis has led to discoveries that are beyond what can be resolved with population-based studies. It provides a pristine view of the mechanisms that organize cellular physiology, unbiased by population heterogeneity or uncontrollable environmental impacts. A holistic description of cellular functions at the single cell level requires analytical concepts beyond the miniaturization of existing technologies, defined but uncontrolled by the biological system itself. This review provides ...

Type 1 metabotropic glutamate receptor and its signaling molecules as therapeutic targets for the treatment of cerebellar disorders.

Neurodegenerative diseases such as spinocerebellar ataxias and autoantibody-associated disorders of the central nervous system often affect the cerebellum, resulting in motor deficits. Recent studies have revealed that most of these disorders impair type 1 metabotropic glutamate receptor (mGluR1) and/or the closely associated signaling molecules in cerebellar Purkinje cell. Since the signaling pathway triggered by mGluR1 activation in Purkinje cell plays a pivotal role in coordinated movements and motor lea...

Innate Immune Signaling in Drosophila Blocks Insulin Signaling by Uncoupling PI(3,4,5)PProduction and Akt Activation.

In obese adipose tissue, Toll-like receptor signaling in macrophages leads to insulin resistance in adipocytes. Similarly, Toll signaling in the Drosophila larval fat body blocks insulin-dependent growth and nutrient storage. We find that Toll acts cell autonomously to block growth but not PI(3,4,5)Pproduction in fat body cells expressing constitutively active PI3K. Fat body Toll signaling blocks whole-animal growth in rictor mutants lacking TORC2 activity, but not in larvae lacking Pdk1. Phosphorylation of...
