poly I:C, being widely used to mimic pathogenic dsRNAs, or viral infection with the RNA virus, encephalomyocarditis (EMCV), led to dramatic and rapid reduction of all examined circRNAs with a turnover half-life of ~1 h. The observed fast turnover of circRNAs upon poly I:C treatment was ...
Serial blockface scanning electron microscopy (SBF-SEM) Embryos were fixed in 2.5% glutaraldehyde in embryo grade water (Sigma, W1503) for 1–2 h at room temperature. Fixed embryos were rinsed with 1x PBS and stored at 4 °C before processing. Processing was performed exactly as describ...
Covalent DNA–protein cross-links (DPCs) are toxic DNA lesions that block replication and require repair by multiple pathways. Whether transcription blockage contributes to the toxicity of DPCs and how cells respond when RNA polymerases stall at DPCs is unknown. Here we find that DPC formation arre...

when the reporting pathologist determines that additional testing is necessary to establish the tumour’s PD-L1 status. If additional blocks from the same sample are tested, the results from all tested blocks should be combined as though testing had been carried out in a single paraffin block [...
CO2is an important component of pH regulatory mechanisms in biological systems. In an aqueous environment, dissolved CO2partially reacts with water to form H2CO3, which dissociates into HCO3−and H+. The balance between H2CO3and HCO3−levels underlies the most important mechanism of maintaining...
A third study from the Peloton Therapeutics group described an orally active small-molecule inhibitor named PT2385, which is structurally similar to PT2399 (Fig.9B), as a specific antagonist of HIF2α, which can allosterically block PT2385 dimerization with the HIF1α/2α transcriptional partners...
To ensure representativeness and homogeneity, the whole dots were observed in tissue microarray, and 5 fields of immune cell highly infiltrated tumor area were selected in the FFPE block slide. All the evaluation was performed by the same pathologist blinded to patient characteristics. Tumor ...
Right: The covariance matrix across 10 such randomly-drawn cells showing loss of signal in the 3 block diagonal covariances. We assume the model for lj captures real single-cell measurements and the goal is to normalize data by converting it to follow the model for yj. (H) Finite state ...
