Background: Obesity is associated with an increased risk of aortic diseases and operative risks. Currently, there are no effective drugs available to prevent the occurrence and progression of aortic aneurysms or dissections. We investigated potential biomarkers and therapeutic targets using a multi-omics approach.

-methyladenosine (mA) is a widespread post-transcriptional modification of RNA in eukaryotes. The conserved YTH-domain-containing RNA binding protein has been widely reported to serve as a typical mA reader in various species. However, no studies have reported the mA readers in ().

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by tremor, rigidity, and bradykinesia, beginning with early loss of dopaminergic neurons in the ventrolateral substantia nigra and advancing to broader neurodegeneration in the midbrain. The clinical heterogeneity of PD and the lack of specific diagnostic tests present significant challenges, highlighting the need for reliable biomarkers for early diagnosis. Alpha-synuclein (α-Syn), a protein aggregating into Lewy bodies and neurites in PD patients, has emerged as a key biomarker due to its central role in PD pathophysiology and potential to reflect pathological processes.

Identifying cellular markers within archived formalin-fixed, paraffin-embedded (FFPE) tissues is critical for understanding tissue landscapes impacting animal health, but in situ detection methods are limited in veterinary species by a restricted toolbox of species-compatible immunoreagents. We identify antibodies with conserved in situ reactivity to IBA-1 (macrophages/dendritic cells), CD3ε (T cells), Pax5 (B cells), Ki-67 (cycling cells), and cytokeratin type I/II (epithelial cells) in FFPE tissues of pigs, cattle, and white-tailed deer. Multiplexed brightfield detection (IBA-1/CD3ε/Pax5) in lymph nodes of all three species demonstrated species-specific and species-conserved features of cellular architecture.

Arrayed CRISPR libraries extend the scope of gene-perturbation screens to non-selectable cell phenotypes. However, library generation requires assembling thousands of vectors expressing single-guide RNAs (sgRNAs). Here, by leveraging massively parallel plasmid-cloning methodology, we show that arrayed libraries can be constructed for the genome-wide ablation (19,936 plasmids) of human protein-coding genes and for their activation and epigenetic silencing (22,442 plasmids), with each plasmid encoding an array of four non-overlapping sgRNAs designed to tolerate most human DNA polymorphisms.
