In the emerging field of optogenetics, light-sensitive G-protein coupled receptors (GPCRs) allow for the temporally precise control of canonical cell signaling pathways. Expressing, stimulating, and measuring the activity of light-sensitive GPCRs (e.g.

YTHDF2, the first identified m6A reader in mammals, has garnered significant attention because of its profound effect to regulate the m6A epitranscriptome in multiple biological processes. Here, we review current knowledge on the mechanisms by which YTHDF2 exerts its functions and discuss recent advances that underscore the multifaceted role of YTHDF2 in development, stem cell expansion and immune evasion.

SP140, a lymphocytic-restricted protein, is an epigenetic reader working as a corepressor of genes implicated in inflammation and orchestrating macrophage transcriptional programs to maintain cellular identity. Reduced SP140 expression is associated both to autoimmune diseases and blood cancers. However, the molecular mechanisms that link SP140 altered protein levels to detrimental effects on the immune response and cellular growth, as well as the interactors through which SP140 promotes gene silencing, remain elusive.

Background An accurate method of assessing the response of muscle-invasive bladder cancer (MIBC) to neoadjuvant treatment is needed for selecting candidates for bladder-sparing strategies. Purpose To evaluate the diagnostic accuracy and reproducibility of neoadjuvant chemotherapy Vesical Imaging Reporting and Data System (nacVI-RADS) scores and posttreatment Vesical Imaging Reporting and Data System (VI-RADS) scores when assessing MIBC response to neoadjuvant immunotherapy with multiparametric MRI (mpMRI). Materials and Methods A retrospective analysis of MRI scans was conducted in patients enrolled in the PURE-01 study (NCT02736266) from February 2017 to December 2019 who underwent pre- and postimmunotherapy mpMRI before radical cystectomy.
