Role of cyclic AMP in the control of cell-specific gene expression [PDF]

open access: yes, 1993
Genes have to be expressed in specific cell types at appropriate times of development dependent on external signals. cAMP signaling occurs in all cells, thus raising the question of how this signal transduction pattern is integrated into mechanisms ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Unraveling the role of cAMP signaling in Giardia: insights into PKA-mediated regulation of encystation and subcellular interactions

open access: yesmSphere
cAMP plays an important role as a second messenger in the stage transition of various protozoan parasites. This signaling pathway relies on multiple effectors, such as protein kinase A (PKA), exchange protein activated by cAMP, and cAMP-response element ...

Control of endogenous triglyceride breakdown in the mouse diaphragm.

open access: yesJournal of Lipid Research, 1980
The control of endogenous triglyceride breakdown was studied in vitro, in the incubated intact mouse diaphragm. Isoproterenol (2 microgram/ml) produced parallel increases in glycerol and free fatty acid release, and in tissue cyclic AMP levels ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

open access: yesMolecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Spatial heterogeneity of hotspot mutations and clonal relatedness in ovarian endometrioid carcinoma

open access: yesMolecular Oncology, EarlyView.
Spatially resolved analysis revealed heterogeneous distributions of selected cancer‐associated mutations within ovarian endometrioid carcinomas. Shared mutations between paired endometrial and ovarian tumors supported clonal relatedness. These findings highlight the value of sampling multiple tumor regions when interpreting molecular profiles ...

Crystal Structure of the Escherichia coli Fic Toxin-Like Protein in Complex with Its Cognate Antitoxin [PDF]

open access: yes, 2016
FIC domain proteins mediate post-translational modifications of target proteins, which typically results in their inactivation. Depending on the conservation of crucial active site residues, the FIC fold serves as structural scaffold for various ...

The multifaceted roles of lysosomes in cancer

open access: yesMolecular Oncology, EarlyView.
Lysosomes support cancer cell adaptation by integrating macromolecule degradation and nutrient recycling with nutrient sensing, inter‐organelle communication and immune regulation. These interconnected functions can promote tumour growth, stress tolerance and therapy resistance, while also creating context‐dependent vulnerabilities that may be ...

(Z)-2-(5-Methyl-2-oxoindolin-3-ylidene)-N-phenylhydrazinecarbothioamide

open access: yesActa Crystallographica Section E, 2011
In the title compound, C16H14N4OS, the dihedral angle between the nine-membered 5-methylindolin-2-one ring system and the benzene ring is 10.21 (7)°.
