During early pregnancy, uterine epithelial cells undergo major transformations in their cytoskeleton that make the endometrium receptive for conceptus attachment. Actin binding proteins (ABPs) such as cofilin, gelsolin, and vinculin are involved in regulating actin polymerization, severing or crosslinking actin to integrins. However, whether ABPs are involved in epithelial remodeling or embryo adhesion in pigs is unknown. Therefore, the expression and distribution of these proteins were investigated in porcine endometrium on Days 10 and 13 (pre-implantation period), and 16 (attachment phase) of the estrous cycle or pregnancy...

Protein aggregation is a hallmark of several degenerative diseases, including Alzheimer's disease, Parkinson's disease and familial amyloidosis (Finnish type) (FAF). A method to isolate and detect amyloids is desired for the diagnosis of amyloid diseases. Here, we report the synthesis of pentameric thiophene amyloid ligand (p-FTAA) linked to agarose resin for selective purification of amyloid aggregates produced in vitro and in vivo. Using amyloid fibrils produced in vitro from alpha-synuclein, gelsolin and Aβ1-40 and gelsolin amyloid aggregates extracted from tissue homogenates of a mouse model of FAF, we observed that p-FTAA resin was able to pull down amyloid aggregates...

FGF8 specifies early tooth development by directing the migration of the early tooth founder cells to the site of tooth emergence. To date the effect of the FGF8 in adult dental pulp has not been studied. We have assessed the regenerative potential of FGF8 by evaluating changes in the proteome landscape of dental pulp following short- and long-term exposure to recombinant FGF8 protein. In addition, we carried out qRT PCR analysis to determine extracellular/adhesion gene marker expression and assessed cell proliferation and mineralization in response to FGF8 treatment...

Breast Cancer (BC) remains a major cause of mortality, and early detection is considered important for reducing BC-associated deaths. Early detection of BC is challenging in young women, due to the limitations of mammography on the dense breast tissue of young women. We recently reported results of a pilot proteomics study, using one-dimensional polyacrylamide gel electrophoresis (1D-PAGE) and mass spectrometry (MS) to investigate differences in milk proteins from women with and without BC. Here, we applied two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and MS to compare the protein pattern in milk from the breasts of a single woman who was diagnosed with BC in one breast 24 months after donating her milk...

Little is known about plasma proteins that can be used as biomarkers for early and late responses to radiation. The purpose of this study was to determine a link between depletion of plasma gelsolin (pGSN) and cell-death as well as inflammatory responses in the lung (one of the tissues known to be radiosensitive) of the same exposed CBA/CaJ mice after exposure to heavy silicon (28 Si) ions. To prevent the development of multiple organ dysfunctions, pGSN (an important component of the extracellular actin-scavenging system) is responsible for the removal of actin that is released into the circulation during inflammation and from dying cells...

Galectin-3 (Gal-3) is a chimeric protein structurally composed of unusual tandem repeats of proline and short glycine-rich segments fused onto a carbohydrate recognition domain. Our studies have previously demonstrated that Gal-3 drives oligodendrocyte (OLG) differentiation to control myelin integrity and function. The cytoskeleton plays a key role in OLG maturation: the initial stage of OLG process extension requires dynamic actin filament assembly, while subsequent myelin wrapping coincides with the upregulation of actin disassembly proteins which are dependent on myelin basic protein (MPB) expression...

Evidence for a critical pathophysiological role of aberrant cytoskeletal dynamics is being uncovered in a growing number of neuropsychiatric syndromes. A sedentary lifestyle as well as overt psychopathology is prevalent in patients with the metabolic syndrome. Using mice deficient in gelsolin (Gsn-/- ), a crucial actin-severing protein, we here investigated reduced actin turnover as a potential common driver of metabolic disturbances, sedentary behavior, and an anxious/depressive phenotype. Gelsolin deficiency resulted in reduced lifespan...

Extracellular vesicles (EVs) are released from nearly all mammalian cells and different EV populations have been described. Microvesicles represent large EVs (LEVs) released from the cellular surface, while exosomes are small EVs (SEVs) released from an intracellular compartment. As it is likely that different stimuli promote the release of distinct EV populations, we analyzed EVs from human lymphocytes considering the respective release stimuli (activation Vs. apoptosis induction). We could clearly separate two EV populations, namely SEVs (average diameter <200 nm) and LEVs (diameter range between 200 and 1000 nm)...

BACKGROUND Gelsolin amyloidosis is a very rare systemic disease presenting with a pathognomonic triad of corneal lattice dystrophy, cutis laxa, and polyneuropathy. The disease is mostly restricted to a Finnish population with known mutations (G654A, G654T) in exon 4 of the gelsolin gene. The mutations lead to errors in protein processing and folding, and ultimately leads to deposition of an amyloidogenic fragment in the extracellular space, causing the symptoms of disease. CASE REPORT We present a case of gelsolin amyloidosis in a male of African descent with an atypical clinical presentation including fevers, skin rash, polyneuropathy, and anemia...

Gelsolin is an actin binding protein present in blood plasma and in cytoplasm of cells including macrophages. Gelsolin has important functions in cell cycle regulation, apoptotic regulation, and morphogenesis. Even though bone marrow macrophages and serum factors are critical for regulating erythropoiesis, the role of gelsolin on human erythroblasts has not been studied. Here, we investigated the effects of human recombinant plasma gelsolin (pGSN) on human immature erythroblasts. CD34+ cells isolated from cord blood were differentiated into erythroid cells in serum-free medium...

The cyclical interaction between F-actin and myosin in muscle cells generates contractile force. The myosin motor domain hydrolyses ATP, resulting in conformational changes that are amplified by the myosin lever arm that links the motor domain to the rod domain. Recent cryo-electron microscopic data have provided a clear picture of the myosin-ATP-F-actin complex, but structural insights into other stages of the myosin-actin interaction have been less forthcoming. To address this issue, we cross-linked F-actin subunits between Cys374 and Lys191, and separated them by gel filtration...

Silent cerebral infarction is the commonest neurological abnormality in children with sickle cell anemia, affecting 30-40% 14 year olds. There are no known biomarkers to identify children with silent cerebral infarcts and the pathological basis is also unknown. We used an unbiased proteomic discovery approach to identify plasma proteins differing in concentration between children with and without silent cerebral infarcts. Clinical parameters and plasma samples were analysed from 51 children (mean age 11.8 years, range 6-18) with sickle cell anemia (HbSS)...

The genetic and molecular basis underlying fear memory formation is a key theme in anxiety disorder research. Because activating transcription factor 3 ( ATF3 ) is induced under stress conditions and is highly expressed in the hippocampus, we hypothesize that ATF3 plays a role in fear memory formation. We used fear conditioning and various other paradigms to test Atf3 knockout mice and study the role of ATF3 in processing fear memory. The results demonstrated that the lack of ATF3 specifically enhanced the expression of fear memory, which was indicated by a higher incidence of the freeze response after fear conditioning, whereas the occurrence of spatial memory including Morris Water Maze and radial arm maze remained unchanged...

Molecular biomarkers in blood are needed to aid the early diagnosis and clinical assessment of glioblastoma (GBM). Here, in order to identify biomarker candidates in plasma of GBM patients, we performed quantitative comparisons of the plasma proteomes of GBM patients (n = 14) and healthy controls (n = 15) using SWATH mass spectrometry analysis. The results were validated by means of quantitative targeted absolute proteomics analysis. As a result, we identified eight biomarker candidates for GBM (leucine-rich alpha-2-glycoprotein (LRG1), complement component C9 (C9), C-reactive protein (CRP), alpha-1-antichymotrypsin (SERPINA3), apolipoprotein B-100 (APOB), gelsolin (GSN), Ig alpha-1 chain C region (IGHA1), and apolipoprotein A-IV (APOA4))...

The gelsolin family proteins are best known for involvement in cytoskeletal rearrangement by controlling actin organization during a variety of cellular processes. Previously, a 1962 bp cDNA encoding a 41.7 kDa protein with three gelsolin-like domains (G domains) from Dendrorhynchus zhejiangensis was identified and named as DzGSN. In this study, the sequence and function of a novel member of the gelsolin family proteins from D. zhejiangensis have been analyzed. Sequence alignment indicates that DzGSN is highly homologous to human gelsolin (35% identity) and human CapG (36% identity)...

Long non-coding RNA (lncRNA) dysregulation is involved in tumorigenesis and regulation of diverse cellular processes in gliomas. lncRNA SNHG12 is upregulated and promotes cell growth in human osteosarcoma cells. TAR-DNA binding protein 43 (TDP43) functions as an oncogene in various tumors by modulating RNA expression. Downregulation of TDP43 or SNHG12 significantly inhibited malignant biological behaviors of glioma cells. miR-195, downregulated in glioma tissues and cells, significantly impaired the malignant progression of glioma cells...

The actin cytoskeleton fulfills numerous key cellular functions, which are tightly regulated in activity, localization, and temporal patterning by actin binding proteins. Tropomyosins and gelsolin are two such filament-regulating proteins. Here, we investigate how the effects of tropomyosins are coupled to the binding and activity of gelsolin. We show that the three investigated tropomyosin isoforms (Tpm1.1, Tpm1.12, and Tpm3.1) bind to gelsolin with micromolar or submicromolar affinities. Tropomyosin binding enhances the activity of gelsolin in actin polymerization and depolymerization assays...

Hypoxic-ischemic encephalopathy (HIE) is a severe neonatal complication responsible for ∼23% of all neonatal deaths. Also, 30-70% of these patients will suffer lifetime disabilities, including learning impairment, epilepsy or cerebral palsy. However, biomarkers for HIE screening, or monitoring disease progression are limited. Herein, we sought to evaluate the clinical usefulness of plasma-type gelsolin (pGSN) and amyloid-beta (Aβ) 40 and 42 as prognostic biomarkers for HIE. pGSN has been previously suggested as a feasible marker in other brain injuries and amyloid-beta 40 and 42 are classically assessed in neurodegenerative diseases...
