Project description:Chromatin plays a crucial role in the intermediation between cell signaling and gene expression. The nucleolus is sensitive to stress and can orchestrate a chain of cellular events in response to stress signals. Despite being a growth factor, FGF2 has anti-proliferative and tumor-suppressive functions in some cellular contexts. In this work, we investigated how the antiproliferative effect of FGF2 modulates chromatin, nucleolus, and rDNA-associated proteins. The chromatin and nucleolar proteome indicated that FGF2 stimulation modulates proteins related to transcription regulation, particularly rRNA expression, and chromatin remodeling proteins. Upon 24 hrs of FGF2 stimulation, the global transcriptional rate and nucleolus area increased in associationalong with intense nucleolar disorganization detected by fibrillarin dispersion and electron microscopy analyses. We confirmed that FGF2 stimulation induced immature rRNA accumulation by increasing rRNA transcription regardless of changes in ribosome profiling. The rDNA-associated protein analysis reinforced that FGF2 stimulus interferes with transcription and rRNA processing/modification, since the proteins Nolc1 and Tcof1 are were upregulated after FGF2 stimulation. Changes in rRNA expression may be crucial for triggering the antiproliferative effect induced by FGF2 since inhibiting RNA Pol I, responsible for rRNA expression, partially reversed the growth arrest induced by FGF2. Taken together, we demonstrate that the antiproliferative FGF2 stimulus triggers significant transcriptional changes, and modulation modulates of the main cell transcription site, the nucleolus, directly modulating the proteome of the rDNA loci.

Project description:The overall data contains expression profile of rat genes of cardiac fibroblasts. G-protein signaling is regulated in cardiac fibroblasts. The expresssion of angiotensin II receptor or cytokine such as interleukin is regulated by PTX (which is suggested to suppress Gi function) treatment. Keywords: control or PTX treatment Rat cardiac fibroblasts were primarily isolated and plated onto 6 well plate. Cells were treated with water (Ctl 1-3) or PTX for 24 hr (PTX 1-3) and lysed by Buffer RLT. Total RNA was isolated using QIAGEN kit and gene expression was analysed using Affymetrix Gene Chip system and GCOS analysis.

Project description:Gβγ subunits are involved in many different signalling processes in various compartments of the cell, including the nucleus. To gain insight into the functions of nuclear Gβγ, we investigated the functional role of Gβγ signalling in regulation of GPCR-mediated gene expression in primary rat neonatal cardiac fibroblasts. Following activation of the angiotensin II type I receptor in these cells, Gβγ dimers interact with RNA polymerase II (RNAPII). Our findings suggest that Gβ1γ recruitment to RNAPII negatively regulates the fibrotic transcriptional response, which can be overcome by strong fibrotic stimuli. In these specific proteomics experiments, we compared the differential protein abundance in Gβ1 knockdown and WT cardiac fibroblasts following angiotensin II treatment using a bottom-up data-dependent approach.
