Biphasic response of Protein Kinase A to cyclic adenosine monophosphate triggers distinct epithelial phenotypes

ABSTRACT: We postulated that the ability of bPAC-generated cAMP to induce the biphasic response of PKA might have profound and distinct effects on the cellular transcriptome. To test this hypothesis, we carried out mRNA sequencing of MDCKI and MDCKI+bPAC cells under no, low, or high cAMP inputs (0%, 1.7% and 33% blue light duty cycle)

Gene expression in undifferentiated or cyclic adenosine monophosphate-exposed BeWo trophoblast cells

Project description:BeWo trophoblast cells differentiate in response to expsure to cyclic adenosine monophosphate (cAMP) analogs. Differentiation includes syncytialization (fusion) and hormonogenesis. The goal of this study was to globally determine transcripts differentially expressed in BeWo trophoblast cells following a 24-h exposure to 250 uM 8-bromo-cAMP. 3 replicates undifferentiated BeWo trophoblast cells; and 3 replicates BeWo trophoblast cells treated with 250 uM 8-Br-cAMP for 24 h.

Protein interactome of 3’,5’-cyclic adenosine monophosphate reveals its role in regulating the actin cytoskeleton

Project description:Four biological replicates of Arabidopsis seedlings supplemented with 1 µM Br-3’,5’-cAMP, or water (control) were subjected to untargeted proteomics analysis at two time-points: 30 min and 1 h. Rather than wild-type, we used act2act7 mutant because of the evident phenotypic changes associated with the 3’,5’-cAMP supplementation.

Diverse effects of cyclic AMP variants on osteogenic and adipogenic differentiation of human mesenchymal stromal cells

Project description:Osteogenic differentiation of human mesenchymal stromal cells (hMSCs) may potentially be used in cell-based bone tissue-engineering applications to enhance the bone-forming potential of these cells. Osteogenic differentiation and adipogenic differentiation are thought to be mutually exclusive, and although several signaling pathways and cues that induce osteogenic or adipogenic differentiation, respectively, have been identified, there is no general consensus on how to optimally differentiate hMSCs into the osteogenic lineage. Some pathways have also been reported to be involved in both adipogenic and osteogenic differentiation, as for example, the protein kinase A (PKA) pathway, and the aim of this study was to investigate the role of cAMP/PKA signaling in differentiation of hMSCs in more detail. We show that activation of this pathway with dibutyryl-cAMP results in enhanced alkaline phosphatase expression, whereas another cAMP analog induces adipogenesis in long-term mineralization cultures. Adipogenic differentiation, induced by 8-bromo-cAMP, was accompanied by stronger PKA activity and higher expression of cAMP-responsive genes, suggesting that stronger activation correlates with adipogenic differentiation. In addition, a whole-genome expression analysis showed an increase in expression of adipogenic genes in 8-br-cAMP-treated cells. Furthermore, by means of quantitative polymerase chain reaction, we show differences in peroxisome proliferator-activated receptor-gamma activation, either alone or in combination with dexamethasone, thus demonstrating differential effects of the PKA pathway, most likely depending on its mode of activation.

Cyclic AMP signalling controls key components of malaria parasite host cell invasion machinery

Project description:Cyclic nucleotides are important signalling molecules across evolution, but their roles in malaria parasites are poorly understood. We have investigated the role of cAMP in asexual blood stage development of Plasmodium falciparum through conditional disruption of adenylyl cyclase (ACβ) and its downstream effector, cAMP-dependent protein kinase (PKA). We show that both production of cAMP and activity of PKA are critical for erythrocyte invasion, whilst key developmental steps that precede invasion still take place in the absence of cAMP-dependent signalling. We also show that another protein with putative cyclic nucleotide binding sites, PfEpac, does not play an essential role in cyclic nucleotide signalling in blood stages. We identify over 2,000 sites whose phosphorylation is dependent on cAMP signalling and we provide mechanistic insight as to how cAMP-dependent phosphorylation of the cytoplasmic domain of the essential invasion adhesin apical membrane antigen 1 (AMA1) controls erythrocyte invasion.

Photobiomodulation by blue light induces a dose dependent biphasic proliferation curve in human keratinocytes [exp2]

Project description:Photobiomodulation (PBM) with blue light induces a biphasic dose response curve in proliferation of immortalized human keratinocytes (HaCaT), with a maximum proliferative effect reached with 7.5min (10.35J/cm2). The aim of this study was to test the photobiomodulatory effect of 10.35J/cm2 blue light irradiation on cell proliferation, ROS production and gene expression at different time points after irradiation of HaCaT cells in vitro and to compare the results with the anti-proliferative phase of PBM using blue light with 41.4J/cm2. For 10.35J/cm2 cell proliferation was increased for all measured harvesting time points up to at least 24h after irradiation. ROS concentration was increased 30min after irradiation. However, already 1h after irradiation, cells were able to decrease ROS and stabilize the concentration to the basal level. The sudden increase in ROS was even higher when compared to 41.4J/cm2. However, gene expression analysis did not indicate any sign of apoptosis and even indicated an activation of cell survival mechanisms. Furthermore, comparable to 41.4J/cm2, aryl hydrocarbon receptor (AHR) “battery genes” showed a deregulation after blue light irradiation strengthening the hypothesis of AHR as possible target for blue light irradiation.
