Malaria, an infectious disease caused by parasites, still accounts for amounts of deaths annually in last decades. Despite the significance of as a model organism of malaria parasites, our understanding of gene expression of this parasite remains largely elusive since lots of progress on its genome and transcriptome are based on assembly with short sequencing reads. Herein, we report the new version of transcriptome dataset containing all full-length transcripts over the whole asexual blood stages by adopting a full-length sequencing approach with optimized experimental conditions of cDNA library preparation. We have identified a total of 393 alternative splicing (AS) events, 3,623 long non-coding RNAs (lncRNAs), 1,555 alternative polyadenylation (APA) events, 57 transcription factors (TF), 1,721 fusion transcripts in . Furthermore, the shotgun proteome was performed to validate the full-length transcriptome of . More importantly, integration of full-length transcriptomic and proteomic data identified 160 novel small proteins in lncRNA regions. Collectively, this full-length transcriptome dataset with high quality and accuracy and the shotgun proteome analyses shed light on the complex gene expression in malaria parasites and provide a valuable resource for related functional and mechanistic researches on genes.

Background: Compared to the 'neutral' E3, the E4 allele of Apolipoprotein E (APOE) confers up to a 15-fold increase in Alzheimer's Disease (AD) risk. Conversely, the neuroprotective E2 allele decreases AD risk by a similar degree. Here, we aimed to assess the therapeutic potential of cell-type specific allelic 'switching' by investigating the physiological and neuropathological changes associated with an inducible, in vivo APOE4 to APOE2 transition in astrocytes using a novel transgenic mouse model METHOD: The APOE "switch mouse" (APOE4s2) uses the Cre-loxP system to allow for inducible APOE allele switching from E4 to E2.

Background: Fusion genes are important biomarkers in cancer research because their expression can produce abnormal proteins with oncogenic properties. Long-read RNA sequencing (long-read RNA-seq), which can sequence full-length mRNA transcripts, facilitates the detection of such fusion genes. Several tools have been proposed for detecting fusion genes in long-read RNA-seq datasets derived from cancer cells.

Introduction: Orchids are renowned for their intricate floral structures, where sepals and petals contribute significantly to ornamental value and pollinator attraction. In Section , the distinctive curvature of these floral organs enhances both aesthetic appeal and pollination efficiency. However, the molecular and cellular mechanisms underlying this trait remain poorly understood.

The duck industry is vital for supplying high-quality protein, making research into the development of duck skeletal muscle critical for improving meat and egg production. In this study, we leveraged Oxford Nanopore Technologies (ONT) sequencing to perform full-length transcriptome sequencing of myoblasts harvested from the leg muscles of duck embryos at embryonic day 13 (E13), specifically examining both the proliferative (GM) and differentiation (DM) phases. Our analysis identified a total of 5797 novel transcripts along with 2332 long non-coding RNAs (lncRNAs), revealing substantial changes in gene expression linked to muscle development.

Chickens are vital economic poultry and serve as exemplary models for avian research. The incomplete reference genome of chickens and the limited availability of full-length cDNA impede the identification of alternatively spliced transcripts, thereby delaying many fundamental chicken studies. We utilized PacBio Iso-seq technology on various chicken tissues, obtaining 170,162 full-length transcripts through comprehensive transcriptome sequencing and annotation.
