Bleached pigment activates transduction in salamander cones. [PDF]

, 1995
We have used suction electrode recording together with rapid steps into 0.5 mM IBMX solution to investigate changes in guanylyl cyclase velocity produced by pigment bleaching in isolated cones of the salamander Ambystoma tigrinum.

Thermal proteome profiling and proteome analysis using high‐definition mass spectrometry demonstrate modulation of cholesterol biosynthesis by next‐generation galeterone analog VNPP433‐3β in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Elevated level of cholesterol is positively correlated to prostate cancer development and disease severity. Cholesterol‐lowering drugs, such as statins, are demonstrated to inhibit prostate cancer. VNPP433‐3β interrupts multiple signaling and metabolic pathways, including cholesterol biosynthesis, AR‐mediated transcription of several oncogenes, mRNA 5′

Defining the Biologically Plausible Taxonomic Domain of Applicability of an Adverse Outcome Pathway: A Case Study Linking Nicotinic Acetylcholine Receptor Activation to Colony Death

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 71-87, January 2023., 2023
Abstract For the majority of developed adverse outcome pathways (AOPs), the taxonomic domain of applicability (tDOA) is typically narrowly defined with a single or a handful of species. Defining the tDOA of an AOP is critical for use in regulatory decision‐making, particularly when considering protection of untested species.

Gromomycins: An Unprecedented Class of Triterpene Antibiotics Produced by a Novel Biosynthetic Pathway

Angewandte Chemie, EarlyView.
Gromomycins represent a novel class of pentacyclic triterpene antibiotics with a unique biosynthetic pathway independent of the squalene route. These compounds exhibit potent activity against drug‐resistant Gram‐positive pathogens, including MRSA, and their unprecedented cyclization mechanism provides new insight into bacterial triterpene biosynthesis.

Homologous and heterologous desensitization of guanylyl cyclase-B signaling in GH3 somatolactotropes [PDF]

, 2013
The guanylyl cyclases, GC-A and GC-B, are selective receptors for atrial and C-type natriuretic peptides (ANP and CNP, respectively). In the anterior pituitary, CNP and GC-B are major regulators of cGMP production in gonadotropes and yet mouse models of ...

Elucidating prognostic significance of purine metabolism in colorectal cancer through integrating data from transcriptomic, immunohistochemical, and single‐cell RNA sequencing analysis

Molecular Oncology, EarlyView.
Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

GUCY2C maintains intestinal LGR5+ stem cells by opposing ER stress [PDF]

, 2017
Long-lived multipotent stem cells (ISCs) at the base of intestinal crypts adjust their phenotypes to accommodate normal maintenance and post-injury regeneration of the epithelium.

Piezo1 channels enhance anabolic signaling activation induced by electrical stimulation of cultured myotubes

FEBS Open Bio, EarlyView.
By using an electrical pulse stimulation (EPS)‐based in vitro exercise model and chemical activation/inhibition of mechanosensitive Piezo1 channels, we explored changes in protein synthetic response in cultured C2C12 myotubes. Our data showed that application of Piezo1 activator (Yoda1) during EPS significantly enhances the rate of protein synthesis in

Guanylyl cyclase activation reverses resistive breathing–induced lung injury and inflammation [PDF]

, 2015
Inspiratory resistive breathing (RB), encountered in obstructive lung diseases, induces lung injury. The soluble guanylyl cyclase (sGC)/cyclic guanosine monophosphate (cGMP) pathway is down-regulated in chronic and acute animal models of RB, such as ...

Subcellular Clustering of the Phosphorylated WspR Response Regulator Protein Stimulates Its Diguanylate Cyclase Activity

mBio, 2013
WspR is a hybrid response regulator-diguanylate cyclase that is phosphorylated by the Wsp signal transduction complex in response to growth of Pseudomonas aeruginosa on surfaces.
