Human Cytokine Testing on Cell Culture Supernatant for SPHEROIDS project

3D Growth of Endothelial Cells During ISS Space Mission – The SPHEROIDS Project

The April 2017 issue of Biomaterials reports on an automated cell culture unit that was developed for the SpaceX CRS-ISS space mission that resulted in three dimensional growth of human endothelial cells in microgravity.

A spaceflight to the International Space Station, carried out in April – May 2016, included a study to examine endothelial cell (EC) behavior in respect to cellular proliferation and apoptosis under spaceflight conditions to examine the gravity dependency of EC tube formation.

GDF-15 as a Possible Biomarker for Use and Dosing of Metformin in Type II Diabetes

Novel nonglycemic biomarker for metformin

The Outcome Reduction with Initial Glargine Intervention (ORIGIN) trial delivers more insight on biomarkers that have potential to help treat patients with dysglycemia.1 Hertzel C. Gerstein and colleagues report Growth Differentiation Factor 15 as a novel biomarker for the use and dosing of metformin, in a study published in Diabetes Care last month.

Induced immune responses in monkeys alter with movement in social status

Social status can be used as predictor of life expectancy and overall health.  It is easy to conclude that this is a result of better diet, healthcare, and lack of external risk factors but, as a team of researchers reported in the November 25th issue of the journal Science, movement in social status in rhesus macaques influenced changes in immune system phenotypes.

IL-10 (AM0010) phase I trial offers novel mechanism for immune-oncology drugs in solid tumors

More commonly known as an inhibitory cytokine, high doses of IL-10 have been shown to lead to the activation and survival of antigen stimulated CD8 T cells. According to a study published in the Journal of Clinical Oncology, the investigators in this first-in-human, phase 1 clinical trial of IL-10 (AM0010), demonstrate antitumor activity and therapy tolerability in a pretreated population.  The primary endpoint of the study was to establish safety, tolerability and the maximum tolerated dose.  This goal appears to have been met, with a low incidence of adverse events, most of which were temporary or reversible.  The dose-escalation study was followed by a renal cell cancer dose-expansion cohort.

DNA variants correlated with blood based biomarkers may predict disease features within COPD

By Sam LaBrie

Developing precision medicines for COPD is an important goal, as the disease is the third most common cause of death in the developed world and there are relatively few effective therapies. A recent study published in PLOS, Common Genetic Polymorphisms Influence Blood Biomarkers Measurements in COPD, explores the massive datasets from two cohorts, SPIROMICS and COPDGene, in a search for biomarkers linked to various aspects of COPD. Scientists combined single nucleotide polymorphisms (SNPs) and a custom MAP (Multi-Analyte Profile) of Myriad RBM’s serum biomarker assays to identify protein quantitative trait loci (pQTLs), i.e. genetic features that are correlated with variations in protein expression).

Data analysis revealed 527 SNPs that are associated with 38 protein biomarkers (pQTLs). For 13 of these proteins, the pQTL could explain >10% of the variation in expression levels seen in the 2 cohorts, with the strongest influence being ~75% of the change in expression of vitamin D binding protein. Several of the pQTLs show significant associations with disease phenotypes, including the pQTL linked to sRAGE, which has been previously associated with emphysema. A striking finding was that SNPs in the ABO blood group region of the genome are strongly associated with many protein biomarker levels. Interestingly, the ABO blood group and COPD have been linked in earlier studies, confirming that ABO status should be taken into consideration for future COPD studies.

The authors conclude that multi-omics studies like this one are important for understanding complex diseases like COPD.
