Molecular heterogeneities and complex microenvironments bring great challenges for cancer diagnosis treatment. Recent advances in single-cell RNA-sequencing (scRNA-seq) technology make it possible to study cell at transcriptomic level. Here, we develop an R package named scCancer, which focuses on processing analyzing scRNA-seq data research. Except basic steps, this takes several special considerations cancer-specific features. Firstly, the introduced comprehensive quality control metrics....

Newly emerged SARS-CoV-2 variants like JN.1, and more recently, the hypermutated BA.2.87.1, have raised global concern. We recruited two groups of participants who had BA.5/BF.7 breakthrough infection post three doses inactivated vaccines: one group experienced subsequent XBB reinfection, while other received XBB-containing trivalent WSK-V102C vaccine. Our comparative analysis their serum neutralization activities revealed that vaccine induced stronger antibody responses against a wide range...

Abstract Histone deacetylases (HDAC) contain eighteen isoforms that can be divided into four classes. Of these isoform enzymes, class IIa (containing HDAC4, 5, 7 and 9) target unique substrates, some of which are client proteins associated with epigenetic control. Class HDACs reportedly neuronal disorders, making therapeutic targets for treating neurodegenerative diseases. Additionally, reported HDAC inhibitors hydroxamate moiety chelates zinc ion to become the cofactor enzymes. However,...
