AACR2017 Poster download – Modulation of CAF expressed podoplanin activity in TME

By Leave a Comment

This year again, we were pleased to attend the Annual meeting of the AACR (American Association for Cancer Research), which took place in Washington DC, USA at the beginning of April.

Nadia Normand Ph.D. (Business Development Manager, tebu-bio), presented a poster with results from collaborative work between the Centre for Molecular Biophysics of the CNRS (Orléans, France), tebu-bio Laboratories (Le Perray en Yvelines, France), Anaxomics Biotech (Barcelona, Spain) and the Institute of Immunology and Experimental Therapy (Wroclaw, Poland).

miRNome analyses reveal that activity of CAF expressed podoplanin in the tumor microenvironment is modulated by exosome miRNAs involved in the PTEN-PI3K-AKT-mTOR signaling

Best methods for Circulation miRNA profiling (cmiRNA)

By Leave a Comment

We need to find biomarkers for prognostic, diagnostic and personalised treatment development. Notably to fight cancers that affect tissues. Since biopsies are invasive, it’s better to look for biomarkers in body fluids. Indeed, a simple blood sample becomes a kind of ‘liquid biopsy’ to reveal tissues affections. For 13 years, increasing interest has been shown for miRNA as biomarkers and it will last for sure. The 2 main reasons are that they are major regulators of cell processes and they are released from tissues into the blood. They are major biomarker candidates in serum and plasma. Thus, these circulating miRNA (cmiRNA) are the best hope for modern medicine. Still, a lot of research has to be done to determine the specific signature for each pathology, and also depending on the patient background. Obviously, cmiRNA profiling is a key step and requires sensitive and reproducible method. Sequencing, qRT-PCR, several kind of microarrays… Let’s explore together what the best approach could be.

Circulating biomarkers – there's more than human

By 1 Comment

In a previous post, we discussed about how important it is to have research tools that allow to study secretome biomarkers outside the usual human and rodents. Either because other species are important research models, or more importantly, because they are the final patient that will be treated, such as pets or cattle.

miRNAs are key mediators in cell processes, allowing to activate or inhibit the expression of certain genes important in different physiological processes. How miRNAs work, and which ones are relevant, are a hot topic of research nowadays, and important advances are being made in areas such as Oncology and the Immune response. [Read more…]

Biomarker profiling or multiplex quantification for everyone

Many researchers would be keen to identify new targets for their research project: add a new cytokine to the classical inflammatory panels, find the missing link between 2 phosphorylation pathways, dig into the miRNA to find a new therapeutic target…
They expect they’ll need dedicated (and expensive) new equipment. Not necessarily! Let’s take a look at assays that use existing and quite common readers, or that can easily be outsourced to reliable labs…
