Calorie restriction (CR) refers to a reduction of calorie intake without compromising essential nutrients to avoid malnutrition. CR has been established as a non-genetic method of altering longevity and attenuating biological changes associated with aging. Aging is also an important risk factor for erectile dysfunction. The aim of this study was to examine whether CR diet can reverse the age-related alterations of erectile tissue in the aged rat. Four groups of rats were used: young rats (7 months) + ad libitum, aged rats (22 months) + ad libitum, young rats + CR diet, and aged rats + CR diet...

Peripheral blood mononuclear cells (PBMCs) are multipotent, and plasma contains growth factors involving tissue regeneration. We hypothesized that transplantation of PBMC-plasma will promote the recovery of paralyzed facial muscles in Bell palsy. This case report describes the effects of PBMC-plasma transplantations in a 27-year-old female patient with right side Bell palsy. On the affected side of the face, the treatment resulted in both morphological and functional recovery including voluntary facial movements...

In recent years, much research has been suggested and examined for the development of tissue engineering scaffolds to promote cellular behaviors. In our study, RGD peptide and graphene oxide (GO) co-functionalized poly(lactide-co-glycolide, PLGA) (RGD-GO-PLGA) nanofiber mats were fabricated via electrospinning, and their physicochemical and thermal properties were characterized to explore their potential as biofunctional scaffolds for vascular tissue engineering. Scanning electron microscopy images revealed that the RGD-GO-PLGA nanofiber mats were readily fabricated and composed of random-oriented electrospun nanofibers with average diameter of 558 nm...

Myostatin, a negative regulator of skeletal muscle growth, is a promising target for treating muscle atrophic disorders. Recently, we discovered a minimal myostatin inhibitor 1 (WRQNTRYSRIEAIKIQILSKLRL-amide) derived from positions 21-43 of the mouse myostatin prodomain. We previously identified key residues (N-terminal Trp(21), rodent-specific Tyr(27), and all aliphatic amino acids) required for effective inhibition through structure-activity relationship (SAR) studies based on 1 and characterized a 3-fold more potent inhibitor 2 bearing a 2-naphthyloxyacetyl group at position 21...

BACKGROUND/AIM: Muscle relaxants, also known as neuromuscular blocking agents, can block nerve impulses to the muscles and are always used in surgery for general anesthesia. However, the effect of muscle-relaxant anesthetics on cell activity in gastric cancer is currently unknown. The present study aimed to examine and compare the role of three different muscle-relaxant anesthetics in gastric cancer cells. MATERIALS AND METHODS: Gastric cancer cells (SGC7901 and BGC 823) were treated with a different dose of muscle-relaxant anesthetics, Rocuronium bromide (Rb), Vecuronium bromide (Vb) and Cisatracurium Besilate (CB)...

Lysophosphatidic acid (LPA) functions through activation of LPA receptors (LPARs). LPA-LPAR signaling has been implicated in development of fibrosis. However, the role of LPA-LPAR signaling in development of diabetic nephropathy (DN) has not been studied. We examined whether BMS002, a novel dual LPAR1 and LPAR3 antagonist, affects development of DN in endothelial nitric oxide synthase-knockout db/db mice. Treatment of these mice with BMS002 from 8 to 20 weeks of age led to a significant reduction in albuminuria, similar to that observed with renin-angiotensin system inhibition (losartan plus enalapril)...

Filamin B (FLNB) is a large dimeric actin-binding protein which crosslinks actin cytoskeleton filaments into a dynamic structure. Up to present, pathogenic mutations in FLNB are solely found to cause skeletal deformities, indicating the important role of FLNB in skeletal development. FLNB-related disorders are classified as spondylocarpotarsal synostosis (SCT), Larsen syndrome (LS), atelosteogenesis (AO), boomerang dysplasia (BD), and isolated congenital talipes equinovarus, presenting with scoliosis, short-limbed dwarfism, clubfoot, joint dislocation and other unique skeletal abnormalities...

BACKGROUND/AIMS: The enhanced proliferation of pulmonary arterial smooth muscle cells (PASMCs) is a central pathological component in pulmonary arterial hypertension (PAH). Both the Warburg effect and platelet-derived growth factor (PDGF) are involved in the proliferation of PASMCs. However, the mechanism underlying the crosstalk between the Warburg effect and PDGF during PASMC proliferation is still unknown. We hypothesized that PDGF promotes the Warburg effect via activating the phosphatidylinositol 3-kinase (PI3K) signaling pathway and hypoxia-inducible factor 1-α (HIF-1α) in proliferative PASMCs...

The sex-linked dwarf chicken is caused by the mutation of growth hormone receptor (GHR) gene and characterized by shorter shanks, lower body weight, smaller muscle fiber diameter and fewer muscle fiber number. However, the precise regulatory pathways that lead to the inhibition of skeletal muscle growth in dwarf chickens still remain unclear. Here we found a let-7b mediated pathway might play important role in the regulation of dwarf chicken skeletal muscle growth. Let-7b has higher expression in the skeletal muscle of dwarf chicken than in normal chicken, and the expression of insulin-like growth factor 2 mRNA binding protein 3 (IGF2BP3), which is a translational activator of IGF2, showed opposite expression trend to let-7b...

Transforming growth factor (TGF)-β1 has received much attention as a major inducer of epithelial-mesenchymal transition (EMT) in pathological conditions such as cancer and organ fibrosis. In this study, we examined the effect of a novel nucleic acid analog, COA-Cl, on TGF-β1-induced EMT using RLE/Abca3, a cell line having alveolar type II cell-like phenotype. Changes in the cell morphology consistent with EMT were induced by TGF-β1, whereas, this response was suppressed by co-treatment of the cells with COA-Cl...

Pulmonary fibrosis is a progressive and often fatal lung disease characterized by fibroblast proliferation and excessive deposition of extracellular matrix. Both TGF-β and Wnt signaling have been implicated in the regulation of organ fibrosis. However little is known about whether TGF-β-induced gene expression changes in Wnt signaling pathway could predict disease progression. In the study, we investigated the interaction between TGF-β and Wnt signaling in mediating pulmonary fibrosis by big data analysis, in vitro and in vivo experimental studies and clinical data analysis...

The objective of this study was to evaluate the effects of the energy restriction of gestation of adult ewes from day 45 to day 115 on lamb live performance parameters, carcass and meat traits. In experiment I, dietary energy was restricted at 70% of the metabolizable energy (ME) requirements, after which ewes were re-fed ad libitum until lambing. In experiment II, dietary energy was restricted at 60% of the ME requirements, and ewes were re-fed to ME requirements until lambing. All ewes grazed together from the end of the restriction periods to weaning...

OBJECTIVE: Skeletal muscles serve several important roles in maintaining good health. Insulin-like growth factor-1 (IGF-1) is a promoter of protein synthesis in skeletal muscle. Its binding protein, Insulin-like growth factor-binding protein-1 (IGFBP-1) can be one determinant of IGF-1 activity. In the present study we investigate the association between serum IGFBP-1 and muscle mass. DESIGN: Cross-sectional analysis of 4908 women, between 55 and 85years old, participating in the Swedish Mammography Cohort-Clinical...

An alternative treatment for growth hormone deficiency based on hGH-DNA administration, followed by electro gene transfer, was investigated by injecting the plasmid into surgically exposed or non-exposed quadriceps or tibialis muscle of immunodeficient "little" mice. Previously optimized electrotransfer conditions were also improved via a new combination of high/low voltage pulses: after 3 days, serum hGH was determined. Both groups exhibited similar results: 5.0 ± 2.2 (SD) and 3.5 ± 0.9 ng hGH/ml (P>0...

BACKGROUND: Cachexia is a complex metabolic and behavioural syndrome lacking effective therapies. Pancreatic ductal adenocarcinoma (PDAC) is one of the most important conditions associated with cachexia, with >80% of PDAC patients suffering from the condition. To establish the cardinal features of a murine model of PDAC-associated cachexia, we characterized the effects of implanting a pancreatic tumour cell line from a syngeneic C57BL/6 KRAS(G12D) P53(R172H) Pdx-Cre(+/+) (KPC) mouse...

OBJECTIVE: The role of TGF-β (transforming growth factor-β) signaling in abdominal aortic aneurysm (AAA) formation is controversial. Others reported that systemic blockade of TGF-β by neutralizing antibodies accelerated AAA development in angiotensin II-infused mice. This result is consistent with other studies suggesting that TGF-β signaling prevents AAA. Development of a therapy for AAA that exploits the protective actions of TGF-β would be facilitated by identification of the mechanisms through which TGF-β prevents AAA...

Fibroblast Growth Factor 9 (FGF9) is necessary for fetal lung development and is expressed by epithelium and mesothelium. We evaluated the role of FGF9 overexpression on adenoviral-induced pleural injury in vivo and determined the biological effects of FGF9 on mesothelial cells in vitro. We assessed the expression of FGF9 and FGF receptors by mesothelial cells in both Human and mouse lungs. Intrapleural injection of an adenovirus expressing human FGF9 (AdFGF9) or a control adenovirus (Adcont) was performed...

Prostaglandin E2 (PGE2), via cAMP signaling, inhibits a variety of fibroblast functions relevant to fibrogenesis. Among these are their translation of collagen I protein and their differentiation to myofibroblasts. PKA is central to these actions, with cAMP binding to regulatory (R) subunits leading to the release of catalytic subunits. Here we examined the role of specific PKAR subunit isoforms in these inhibitory actions in transforming growth factorβ-1 (TGFβ-1)-stimulated human lung fibroblasts (HLFs)...
