Bivalent coronavirus disease 2019 (COVID) mRNA vaccines encoding Wuhan-1 and Omicron BA.4/BA.5 spike proteins (S) can prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but the quality of adaptive immune responses and the importance of hybrid immunity are not well documented. Adaptive immune responses to the bivalent vaccine were studied in 40 healthy participants with (COVID+) or without (COVID−) history of SARS-CoV-2 infection.

New Results doi: https://doi.org/10.1101/2022.02.18.481000 Abstract Serial RNA-seq studies of bulk samples are widespread and provide an opportunity for improved understanding of gene regulation during e.g., development or response to an incremental dose of a pharmacotherapeutic. In addition, the widely popular single cell RNA-seq (scRNA-seq) data implicitly exhibit serial characteristics because measured gene expression values recapitulate cellular transitions.

Abstract RNA 3′ end processing provides a source of transcriptome diversification which affects various (patho)-physiological processes. A prime example is the transcript isoform switch that leads to the read-through expression of the long non-coding RNA NEAT1_2, at the expense of the shorter polyadenylated transcript NEAT1_1. NEAT1_2 is required for assembly of paraspeckles (PS), nuclear bodies that protect cancer cells from oncogene-induced replication stress and chemotherapy.
