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′

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.

Activation of Adenylyl Cyclase Causes Stimulation of Adenosine Receptors

Cellular Physiology and Biochemistry, 2018
Background/Aims: Signaling of Gs protein-coupled receptors (GsPCRs) is accomplished by stimulation of adenylyl cyclase, causing an increase of the intracellular cAMP concentration, activation of the intracellular cAMP effectors protein kinase A (PKA) and

Current Modulation of Guanylate Cyclase Pathway Activity—Mechanism and Clinical Implications

Molecules, 2021
For years, guanylate cyclase seemed to be homogenic and tissue nonspecific enzyme; however, in the last few years, in light of preclinical and clinical trials, it became an interesting target for pharmacological intervention.

Role of guanylyl cyclase modulation in mouse cone phototransduction [PDF]

, 2011
A negative phototransduction feedback in rods and cones is critical for the timely termination of their light responses and for extending their function to a wide range of light intensities. The calcium feedback mechanisms that modulate phototransduction

Forskolin Enhances Urokinase Plasminogen Activator Secretion and Angiogenic Activity of Xeno‐Free Cultures of Human Adipose Tissue‐Derived Stem Cells

Advanced Biology, EarlyView.
The regenerative potential of adipose tissue‐derived stem cells can be enhanced through chemical stimulation in vitro. A short stimulation protocol using forskolin, either alone or in combination with other growth factors, under xeno‐free conditions enhanced the pro‐angiogenic responses in human ASCs.

The Role of Pseudomonas aeruginosa ExoY in an Acute Mouse Lung Infection Model

Toxins, 2018
The effector protein Exotoxin Y (ExoY) produced by Pseudomonas aeruginosa is injected via the type III secretion system (T3SS) into host cells. ExoY acts as nucleotidyl cyclase promoting the intracellular accumulation of cyclic nucleotides.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Photosensitizer Repositioning Affords an Enantiocomplementary Enzyme for [2 + 2]‐Cycloadditions

Angewandte Chemie, EarlyView.
In this study, we capitalize on the versatility offered by genetic code expansion to develop a proficient photoenzyme for [2 + 2]‐cycloadditions that is enantiocomplementary to our recently developed photoenzyme EnT1.3. By repositioning the genetically programmed benzophenone photosensitizer and subsequent directed evolution, we have developed an ...

Mycobacterium tuberculosis Rv3586 (DacA) is a diadenylate cyclase that converts ATP or ADP into c-di-AMP. [PDF]

PLoS ONE, 2012
Cyclic diguanosine monophosphate (c-di-GMP) and cyclic diadenosine monophosphate (c-di-AMP) are recently identified signaling molecules. c-di-GMP has been shown to play important roles in bacterial pathogenesis, whereas information about c-di-AMP remains
