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...

Alternatively spliced isoforms of certain apoptosis regulators, such as Bcl-x, Ced-4, and Ich-1, have been shown to play opposing roles in regulating apoptosis. Here, we describe the identification of an endogenous alternatively spliced isoform of caspase-9, named caspase-9b, which lacks the central large subunit caspase domain. Caspase-9b is detectable in many cell lines by PCR and at the mRNA...

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 ...

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...

Bacillus subtilis 2C-9B, obtained from the rhizosphere of wild grass, exhibits inhibition against root rot causal pathogens in Capsicum annuum, Pb and Zn tolerance, and plant growth promotion in medium supplemented with Pb. The genome of B. subtilis 2C-9B was sequenced and the draft genome assembled, with a length of 4,215,855 bp and 4,723 coding genes.

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...

A duplexed, functional multiaddition high throughput screen and subsequent iterative parallel synthesis effort identified the first highly selective and CNS penetrant glucagon-like peptide-1R (GLP-1R) positive allosteric modulator (PAM). PAM (S)-9b potentiated low-dose exenatide to augment insulin secretion in primary mouse pancreatic islets, and (S)-9b alone was effective in potentiating endog...
