Growth differentiation factor 11 (GDF-11) has been implicated in reverse effects of ageing on the central nervous system of humans. β2-microglobulin (β2-MG) has been reported to negatively regulate cognition. However, there is a lot of controversy about the role of GDF-11 and β2-MG in ageing and cognitive regulation. To examine the involvement of GDF-11 and β2-MG in the ageing process and cogni...
Background—Growth-differentiation factor-15 (GDF-15) is emerging as a prognostic marker in patients with cardiovascular disease (CVD), but its prognostic value in community-dwelling adults has not been reported. We hypothesized that GDF-15 would add incremental power for prediction of mortality in a population of community-dwelling older adults without known heart disease. Methods and Results—W...
Cellular activities responding to growth factors are important in ligament healing. The anterior cruciate ligament (ACL) has poor healing potential compared to the medial collateral ligament (MCL). To assess the differences, we investigated the proliferation, migration, adhesion, and matrix synthesis responding to growth factors in rabbit ACL and MCL fibroblasts. ACL cell proliferation to basic...
Protein synthesis factor eIF2 delivers initiator tRNA to the ribosome. Two proteins regulate its G-protein cycle: eIF5 has both GTPase-accelerating protein (GAP) and GDP dissociation inhibitor (GDI) functions, and eIF2B is the guanine nucleotide exchange factor (GEF). In this study, we used protein-protein interaction and nucleotide exchange assays to monitor the kinetics of eIF2 release from t...
In addition to its roles in embryonic development, Growth and Differentiation Factor 11 (GDF 11) has recently drawn much interest about its roles in other processes, such as aging. GDF 11 has been shown to play pivotal roles in the rescue of the proliferative and regenerative capabilities of skeletal muscle, neural stem cells and cardiomyocytes. We would be remiss not to point that some controv...
BACKGROUND The cytokine growth differentiation factor-15 (GDF-15), a member of the TGF beta superfamily, has recently been discovered to play an important role in cardiovascular diseases. It is mostly expressed in macrophages of atherosclerotic lesions, but its impact on advanced atherosclerosis is still unknown. This study was performed to evaluate the effects of GDF-15 in an established mouse...
Intervertebral disc degeneration (IDD) is a widely recognized contributor to low back pain (LBP). The Prevention or reversal of IDD is a potential treatment for LBP. Unfortunately, current treatments for IDD are aimed at relieving symptoms rather than regenerating disc structure or function. Recently, the injection of growth factors and mesenchymal stem cell (MSC) transplantation have been show...
AIMS Our aim was to assess the long-term prognostic value of growth differentiation factor-15 (GDF-15) in patients post-acute myocardial infarction (AMI). Growth differentiation factor-15 is a member of the transforming growth factor beta family. Growth differentiation factor-15 is expressed in the myocardium and upregulated due to 'stress' and has been shown to have antiapoptotic actions. Its ...
Risk stratification in critically ill patients: GDF-15 scores in adult respiratory distress syndrome
Patients with adult respiratory distress syndrome (ARDS) are highly heterogeneous but current therapies are rather uniform and largely supportive. In the previous issue of Critical Care, Clark and colleagues report that the biomarker GDF-15 provides prognostic information in ARDS that is additive to that provided by the APACHE III score. Patients with high levels of growth-differentiation facto...
The growth/differentiation factors (GDFs) are a subgroup of the bone morphogenetic proteins best known for their role in joint formation and chondrogenesis. Mice deficient in one of these signaling proteins, GDF-5, exhibit numerous skeletal abnormalities, including shortened limb bones. The primary aim of this study was determine whether GDF-5 deficiency would alter the growth rate in growth pl...
