MetabolomicsPKA regulates stress granule maturation to allow timely recovery after prolonged starvation
Cells have evolved multiple strategies to survive environmental stress conditions. This includes the formation of membrane-less cytoplasmic ribonucleoprotein structures called stress granules that sequester and protect mRNAs encoding many housekeeping genes. Stress granules are not static biomolecul...

MetabolomicsSemen Cuscutae flavonoids activated the cAMP-PKA-CREB-BDNF pathway and exerted an antidepressant effect in mice

Background: Semen Cuscutae flavonoids (SCFs) constitute a class of metabolites of Semen Cuscutae, a botanical drug that was recently found to have an anti-depression effect. This study aimed to evaluate the anti-depression effects of SCFs in chronic unpredi...

ProteomicsIdentifications of protein kinase A substrates with quantitative phosphoproteomics and primary-sequence based scoring.(H-89)
Protein kinase A (PKA) is a serine/threonine kinase who plays essential roles in the complex signalling pathways. To better understand the functionalities, it is necessary to elucidate direct interplays between PKA and their substrates in living system. In order to screen them in a high-throughput m...

ProteomicsSmoothened Transduces Hedgehog Signals via Activity-Dependent Sequestration of PKA Catalytic Subunits
The Hedgehog (Hh) pathway is essential for organ development, homeostasis, and regeneration. Dysfunction of this cascade drives several cancers. To control expression of pathway target genes, the G protein-coupled receptor (GPCR) Smoothened (SMO) activates glioma-associated (GLI) transcription facto...

TranscriptomicsExploring the scope of TOR/PKA co-regulation in MDN
To identify genes co-regulated by TOR and PKA during growth in MDN BCY1, bcy1 deletion, TPK, and tpk1-3 deletion strains were grown in MDN with and without rapamycin treatment. Different combinations of these samples were examined.

TranscriptomicsTranscription profiling of mouse S49 cells to study the global impact of cAMP and protein kinase A on gene expression
Although a substantial number of hormones and drugs increase cellular cAMP levels, the global impact of cAMP and its major effector mechanism, protein kinase A (PKA), on gene expression is not known. Here we show that treatment of wild-type S49 lymphoma cells for 24 h with 8-(4-chlorophenylthio)-cAM...

TranscriptomicsTranscription profiling by array of human ovarian cancer cells overexpressing PKA regulatory subunits
The regulatory subunit of cAMP-dependent protein kinase (PKA) exists in two isoforms, RI and RII, which distinguish the PKA isozymes, type I (PKA-I) and type II (PKA-II). Evidence obtained from a variety of different experimental approaches has shown that the relative levels of type I and type II PK...

MetabolomicsStress-related mitogen-activated protein kinases stimulate the accumulation of small molecules and proteins in Arabidopsis thaliana root exudates
A delicate balance in cellular signaling is required for plants to distinguish mutualist from parasitic organisms in its environment. Mitogen-activated protein kinase (MAPK) cascades are one of the signaling modules that mediate transduction of extracellular microbial signals into appropriate cellul...

TranscriptomicsTranscription profiling of mouse S49 lymphoma cell deathless (D-) cell variant
The second messenger cAMP acts via protein kinase A (PKA) to induce apoptosis by mechanisms that are poorly understood. Here, we assessed a role for mitochondria and analyzed gene expression in cAMP/PKA-promoted apoptosis by comparing wild-type (WT) S49 lymphoma cells and the S49 variant, D- (cAMP-d...
