Article Abstract
As an important mechanism in the post-transcriptional regulation of eukaryotic gene expression, alternative polyadenylation (APA) plays a key role in biological processes such as cell proliferation and differentiation. However, the role and dynamic pattern of APA during metamorphosis are poorly understood. Here, RNA-seq data covering from the embryo to the maturation (16 time points) of were utilized. We identified 247 differentially expressed APA events between early and adult stages, and through fuzzy mean clustering analysis, we discovered five dynamic APA patterns. Among them, the gradual elongation of the 3'UTR is the major APA pattern that changes over time, and its genes are enriched in the pathways of protein and energy metabolism. Finally, we constructed mRNA-miRNA and PPI networks and detected several central miRNAs that may regulate development. Our results revealed the complex APA mechanisms in metamorphosis, shedding new light on post-transcriptional regulation of crustacean metamorphosis.

Stage specific increased expression of PCF11 and Cbc, the two components of Cleavage Factor complex II, contribute to developmentally regulated 3'UTR shortening due to alternate polyadenylation of nascent RNA molecules in spermatocytes. Here, we show that both Cbc and PCF11 change subnuclear localization during male germ cell differentiation, from homogeneous in the nucleus in spermatogonia and early spermatocytes to concentrated around the nucleolus in later spermatocyte stages.

Introduction: DMRT1 on the Z chromosome is a conserved male sex-determining gene in birds. In chickens, a representative model species of Neognathae, the function of DMRT1 has been well characterized. In contrast, Palaeognathae species such as the emu possess less differentiated sex chromosomes and thus provide a valuable system for investigating avian sex determination, yet molecular studies remain limited.

Genome-wide spatial long-read approaches often lack single-cell resolution and yield limited read lengths. Here, we introduce spatial ISOform sequencing (Spl-ISO-Seq), which reveals exons and polyadenylation sites with near-single-cell resolution. Spl-ISO-Seq selects long cDNAs and doubles to triples read lengths compared to standard preparations.

Through mechanotransduction, cells sense and respond to mechanical stimuli from their environment. A mechanical stimulus is first detected by a mechanosensor, then converted into a biochemical signal, which can ultimately control the expression of genes. RNA processing, which includes canonical and alternative splicing, 3' end polyadenylation, and 5' end capping, is a mechanism that fine-tunes gene expression regulation.

Performing total RNA profiling on formalin-fixed, paraffin-embedded (FFPE) samples, the predominant sample conservation method in clinical practice, remains challenging for current spatial transcriptomics techniques. Here, we introduce Stereo-seq V2, which employs random primers to capture and sequence RNAs in situ on FFPE sections and provides single-cell resolution. The random-priming-based strategy offers unbiased transcript capturing and uniform gene body coverage, which increase the sensitivity to marker genes, the efficiency of non-polyadenylation (poly(A)) RNA profiling, and immune repertoire coverage.
