A limited delivery of oxygen and metabolic substrate to the heart caused by myocardial infarction (MI) impairs the cardiac function, and often results in heart failure. Here, we identified a circRNA (circ-SNRK) from SNRK (sucrose nonfermenting 1-related
Based on the findings of this study and our previous study, we propose that there is a negative feedback loop involving NRF2 and p97. However, this loop becomes disrupted in lung cancer as NRF2 is no longer ubiquitylated by the KEAP1-CUL3-RBX1 E3 complex, resulting in hyperactivation of ...
The NF-κB-mediated induction of their own regulators comprises autonomous negative feedback loops giving rise to transient expression of NF-κB activity. While searching for roles for inducible proteins upon inflammation, we and others identified an ankyrin-repeat-containing protein that was strongly ...
In particular, we found high SHIP1 expression in both, Philadelphia chromosome (Ph)-positive and ETV6-RUNX1-rearranged B-ALL cells. As demonstrated by targeted knockdown of SHIP1 by RNA interference, proliferation of B-ALL cells in vitro and their tumorigenic spread in vivo depended in part ...
we used the edgeR functions glmQLFit and glmQLFTest to perform a quasi-likelihood dispersion estimation and hypothesis testing that assigns FDR values to each gene. In the track scRNAseq plots in Fig.3and Additional file 1: Figure S5, a positive log 2 fold change value for Clone X relativ...
When dealing with negative feedback systems, the description through a low-order model is encouraged by the fact that a well-designed closed-loop system can be usually described, in first approximation, by a first- or second-order linear model [33]. In this framework, the objective of this...
