Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor characterized by ETV6 translocation. It appears that prior studies have identified MASC by reviewing salivary gland carcinomas, such as acinic cell carcinoma and adenocarcinoma, not otherwise specified. To address the possibility of MASC mimicking benign salivary neoplasms we ...

This study reports a strategy that allows one to finely tune the distance between Ag nanoparticles decorated on thermoresponsive microgels to create vast 'hot spots' for electromagnetic enhancement. The dynamic gap (i.e. the interparticle distance) can be tuned easily because the microgel template undergoes a phase transition upon changing the ...

MicroRNAs (miRNAs) post-transcriptionally repress gene expression via the miRNA-induced silencing complex (miRISC), which includes miRNA, Argonaute and a GW182 family member. Here we show that in Caenorhabditis elegans, miRNA-mediated gene silencing is modulated by macroautophagy, a lysosome-mediated degradation process. Loss of autophagy activity suppresses developmental defects caused by partially impaired ...

Modern pharmacometrics can integrate and leverage all prior proprietary and public knowledge. Such methods can be used to scale across species or comparators, perform clinical trial simulation across alternative designs, confirm hypothesis and potentially reduce development burden, time and costs. Crucial yet typically lacking in integration is the pre-clinical stage. ...

The transcription factor Stat3 is an activator of systemic inflammatory genes. Two isoforms of Stat3 are generated by alternative splicing, Stat3α and Stat3β. The β isoform lacks the transactivation domain but retains other functions, including dimerization and DNA binding. Stat3β-deficient mice exhibit elevated expression of systemic inflammatory genes and are ...
