USP15 targets ALK3/BMPR1A for deubiquitylation to enhance bone morphogenetic protein signalling [PDF]

, 2014
Protein kinase ALK3/BMPR1A mediates bone morphogenetic protein (BMP) signalling through phosphorylation and activation of SMADs 1/5/8. SMAD6, a transcriptional target of BMP, negatively regulates the BMP pathway by recruiting E3 ubiquitin ligases and ...

Cytoplasmic and nuclear testosterone receptors in the hypothalamus of androgenized female and castrated male rats

Neuroscience and Behavioral Physiology, 1985
Receptors for testosterone (T) in the preopticoanterior hypothalamus (PO) and in the arcuate nucleus and median eminence (ARC + ME) were examined in neonatally androgenized female and neonatally castrated male rats. As a result of neonatal castration of males, the concentration of cytoplasmic and nuclear receptors for T in the PO dropped to an ...

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Cigarette Smoke Suppresses Type I Interferon-Mediated Antiviral Immunity in Lung Fibroblast and Epithelial Cells [PDF]

, 2008
The objective of this study was to investigate the impact of cigarette smoke on innate antiviral defense mechanisms; specifically, we examined the effects of cigarette smoke on the induction of type I interferon (IFN).

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Intercompartmental communication in senescence

FEBS Open Bio, EarlyView.
Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

Heart-type fatty-acid-binding protein (FABP3) is a lysophosphatidic acid-binding protein in human coronary artery endothelial cells

FEBS Open Bio, 2014
Fatty-acid-binding protein 3, muscle and heart (FABP3), also known as heart-type FABP, is a member of the family of intracellular lipid-binding proteins. It is a small cytoplasmic protein with a molecular mass of about 15 kDa.

Wnt/beta-catenin/Tcf signaling: A critical pathway in gastrointestinal tumorigenesis [PDF]

, 2002
Cancers of the gastrointestinal tract, including the liver, bile ducts, and pancreas, constitute the largest group of malignant tumors. Colorectal cancer is one of the most common neoplastic diseases in Western countries and one of the leading causes of ...

A new procedure for the quantitation of nuclear and cytoplasmic androgen receptors.

Journal of Biological Chemistry, 1981
Experimental conditions for the measurement of prostatic androgen receptors occupied with unlabeled hormone are described. The assay allows quantitation of cytoplasmic and nuclear receptors occupied with unlabeled ligand by exchange with 17 beta-hydroxy-17 alpha-methyl [3H]estra-4,9,11-trien-3-one at 0 degrees C.

Blood‐based proteomic profiling reveals context‐dependent changes in BCL2‐associated signaling during taxane therapy in breast cancer patients

FEBS Open Bio, EarlyView.
Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.
