Structural basis for guanidine sensing by the ykkC family of riboswitches
RNA: A publication of the RNA Society, 2017 Regulation of gene expression by cis-encoded riboswitches is a prevalent theme in bacteria. Of the hundreds of riboswitch families identified, the majority of them remain as orphans, without a clear ligand assignment.

Animal Models and Experimental Medicine, EarlyView.The hypothesis diagram illustrates the function and mechanism of circNR3C2: circNR3C2 overexpression can up‐regulate COL2, Aggrecan and SOX9 expression, and regulate chondrogenic differentiation of hADSCs by targeting hsa‐miR‐647. Abstract Background Human adipose‐derived stem cells (hADSCs) are seed cells with application prospects in cartilage repair.

Annals of Neurology, EarlyView.Objective Quaking‐induced conversion (QuIC) tests, which detect prion‐seeding activity in cerebrospinal fluid (CSF), have markedly advanced the antemortem diagnosis of prion diseases such as Creutzfeldt‐Jakob disease (CJD). These tests provide high diagnostic accuracy and enable timely differentiation from other rapidly progressive neurodegenerative ...
