Background: Intermediate filament proteins that construct the nuclear lamina protein lamin cell including A / C is encoded by the gene LMNA, and is involved in fundamental processes such as nuclear structure, gene expression and signal transduction. LMNA mutations predominantly affect the mesoderm-derived cell lineages in diseases collectively referred to as laminopathies which include dilated cardiomyopathy with conduction defects, various forms of muscular dystrophy and premature aging syndromes as Hutchinson-Gilford Progeria Syndrome. At present, our understanding of the molecular mechanisms that regulate tissue-specific manifestations of laminopathies still limited.
Methods: To gain more insight into the molecular mechanisms of a novel splice-site mutations in LMNA (c.357-2A> G) in a family affected by heart disease, we do deep RNA sequencing and analysis for the nine lines derived fibroblast samples three patients with cardiomyopathy, three unaffected family members, and three unrelated individuals not affected. We validated our findings by the study of quantitative PCR and protein.
Results: We identified eight genes were significantly differentially expressed between fibroblasts mutant and non-mutant, which included downregulated factor insulin growth factor binding protein 5 (IGFBP5) in patient samples. ERK pathway analysis indicates involvement / MAPK signaling pathways consistent with previous studies. We found no significant differences in gene expression of lamin A / C and B-type lamins between groups. In the mutant fibroblasts, RNA-seq confirmed that only LMNA predominantly expressed wild-type allele, and Western blot showed normal levels of the protein lamin A / C
Conclusion: IGFBP5 can contribute in maintaining homeostasis pathway signaling, which may cause the molecular and structural abnormalities is important in the network are not affected as fibroblasts. the mechanism of compensation of other nuclear membrane protein was not found. Our results also showed that only one copy of the wild allele kind enough to normal levels of the protein lamin A / C to maintain physiological functions in the cell type affected. This indicates that the affected cell types such as heart tissue may be more sensitive to haploinsufficiency of lamin A / C. These results provide insight into the molecular mechanisms of diseases with a possible explanation for tissue specificity LMNA related dilated cardiomyopathy.

Description: FGF acidic is a 17 kDa nonglycosylated member of the FGF family of mitogenic peptides. FGF acidic, which is produced by multiple cell types, stimulates the proliferation of all cells of mesodermal origin and many cells of neuroectodermal, ectodermal, and endodermal origin. It plays a number of roles in development, regeneration, and angiogenesis. FGF-acidic is a non-glycosylated heparin binding growth factor that is expressed in the brain, kidney, retina, smooth muscle cells, bone matrix, osteoblasts, astrocytes and endothelial cells. FGF-acidic has the ability to signal through all the FGF receptors.
Description: FGF acidic, also known as ECGF, FGF-1and HBGF-1, is a non-glycosylated heparin binding growth factor that is expressed in the brain, kidney, retina, smooth muscle cells, bone matrix, osteoblasts, astrocytes and endothelial cells. It is a mitogenic peptide that is produced by multiple cell types and stimulates the proliferation of cells of mesodermal, ectodermal, and endodermal origin. Its association with heparan sulfate is a prerequisite for activation of FGF receptors. Internalized FGF acidic migrates to the nucleus where it is phosphorylated by nuclear PKC delta, exported to the cytosol, dephosphorylated, and degraded. Intracellular FGF acidic inhibits p53 activity and proapoptotic signaling.

Description: Heparin-binding growth factor 1 is a protein that in humans is encoded by the FGF1 gene. The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF acidic is a potent growth factor for fibroblasts and endothelial cells. FGF acidic is involved in wound repair, angiogenesis, and development. FGF acidic is secreted from cells via an endoplasmic reticulum/Golgi independent mechanism. The ability of FGF acidic to bind to heparin sulfate is required for its ability to interact with FGF receptors and induce signaling. There are four distinct FGF receptors and each has multiple splice variants. FGF acidic binds with high affinity to many, but not all, FGFRs. Signaling cascades activated through FGF basic binding to FGFR include the ras-raf-MAPK, PLCγ/PKC, and PI3K/Akt pathways.
Description: The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Multiple alternatively spliced variants encoding different isoforms have been described.

Description: Acidic Fibroblast Growth Factor Intracellular-Binding Protein (FIBP) is highly expressed in the heart, skeletal muscle, and pancreas. Acidic Fibroblast Growth Factor is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. FIBP is an intracellular protein that binds selectively to acidic fibroblast growth factor (aFGF). It is postulated that FIBP may be involved in the mitogenic action of aFGF.
After 72 hours of incubation, the degree of inhibition was greater in the combination group than all the single drug groups. Similar results were found when apoptosis was assessed after 12 h, but not after 6 hours of treatment. Compared with a single drug, drug combination suppressed the migration and invasion ability in two cell lines; However, there is no difference between anlotinib individual or irinotecan. Colony formation rates clearly lowered in the combination group.
