Summary: The study reveals the prevalence of highly splicing complex exons in mammals and their correlation with gene features. The splicing complexity of exons can be moderately predicted using machine learning and deep learning methods. Both developmentally regulated and non-developmentally regulated exons show dynamic splicing complexity during organ development.

Summary: The dysregulation of alternative splicing in cancer is commonly observed and serves as a crucial indicator for cancer progression and therapy. Transformer 2 (TRA2), a nuclear RNA binding protein, consisting of TRA2A and TRA2B, has been found to be dysregulated in various types of tumors. It modulates the proliferation, migration, invasion, and chemotherapy resistance of cancer cells by altering the alternative splicing of cancer-related genes. This review focuses on the role of TRA2 in tumorigenesis and metastasis, and discusses the potential molecular mechanisms by which TRA2 influences these processes through controlling alternative splicing. We propose that TRA2A is a novel biomarker and therapeutic target for cancer progression and therapy.

Summary: Serine-and arginine-rich splicing factors play important roles in regulating splicing by binding to cis-acting elements in precursor mRNAs and facilitating spliceosome assembly. SR proteins also have diverse functions in RNA metabolism as they shuttle between the nucleus and cytoplasm. Overexpression and/or hyperactivation of SR proteins have been associated with tumorigenesis, suggesting their potential as therapeutic targets. This review highlights the physiological and pathological roles of SR proteins and discusses small molecules and oligonucleotides that can modulate SR protein function for future studies.

Summary: In this study, the transcriptome changes in response to glucose stress in Arabidopsis seedlings were investigated using Oxford Nanopore sequencing technologies. The results showed that glucose stress affects alternative splicing (AS) of many genes, including the glycine-rich protein (GRP) family and arginine/serine-rich splicing factor 31 (RS31). The findings provide insights into the regulatory mechanism of AS in sugar signaling.

Summary: Alternative splicing (AS) is a mechanism that generates multiple mature transcripts from protein-coding genes and long non-coding RNA (lncRNA) genes, increasing transcriptome complexity and producing different protein isoforms. Despite the identification of numerous alternatively spliced transcripts, the low detection rate of protein isoforms has raised questions about the contribution of AS to proteomic diversity and the functional relevance of AS events.

Summary: Alzheimer's disease is the most common neurodegenerative disorder in the elderly, with approximately 20% of people over 80 affected. Recent studies have shown that Alternative Splicing is involved in gene expression reprogramming and splicing abnormalities in AD tissues. While the molecular causes of AD are still poorly understood, therapeutic approaches targeting aberrant AS regulation offer potential new treatments.

Summary: This study reveals that calcium binding and myristoylation independently affect the conformation and functions of human CHP3. Calcium binding increases the flexibility and hydrophobicity of CHP3, indicating an open conformation. Myristoylation enhances the flexibility of CHP3 and decreases its affinity to NHE1 independently of the bound ion.

Summary: Alternative splicing is a regulated process that can lead to disease. The SMARTer method provides full-length double-strand cDNA synthesis, but faces non-specific genomic DNA amplification issue. The improved SMARTer Capture method, incorporating target-specific capture with exon probes, can accurately detect more alternative splicing events and reduce non-specific amplification.

Summary: Our study reveals an association between over-expression of sPD-1 protein and PD-1 Delta ex3 transcript in celiac disease. We also discovered three novel alternative spliced isoforms, one of which may encode a new soluble form of PD1 (sPD-1). Dietary gluten can modulate RNA splicing processes in response to different nutritional conditions, suggesting an adaptive mechanism for cell homeostasis.

Summary: We used single-cell whole-genome sequencing to reconstruct the evolutionary trajectory of medulloblastoma, the most common childhood brain malignancy. The different molecular sub-classes and clinical risk groups showed varying levels of clonal diversity and evolutionary patterns. Early-stage chromosomal aberrations and gene mutations can be used as biomarkers for early disease detection. Novel events that occur later and/or sub-clonally may have clinical significance in disease evolution and require further investigation.

Summary: The ssNet integration technique allows for the construction of PFINs from a single database, eliminating the need for an external Gold Standard dataset while producing comparable network performance and reducing data loss. It scores and integrates high-throughput and low-throughput data in a consistent manner, overcoming challenges such as data redundancy and Gold Standard bias. The ssNet method provides a more efficient and complete approach to building functional integrated networks.

Summary: The use of microorganisms for the production of industrially important compounds and enzymes is increasingly important. However, eukaryotes have been less widely used in biotechnology due to their complex genomic structure and biology. The Yeast2.0 project aims to engineer the yeast Saccharomyces cerevisiae to make it easier to manipulate and generate random variants. In this study, we developed a computer simulator for the SCRaMbLE system, which can be used to analyze and optimize the fitness landscape of any organism in which SCRaMbLE has been implemented.

Summary: Currently, the identification of gastrointestinal helminth infections relies on traditional microscopy-based techniques, but molecular approaches using DNA detection and quantification offer increased sensitivity and specificity. In this study, low-depth whole genome sequencing (genome skimming) was used to detect and characterize helminth diversity in faecal samples. Three methods were evaluated to characterize metagenomic sequencing data, and the success of genome skimming was dependent on the availability of reference sequences and methods to detect parasite DNA in mixed samples.

Summary: This study used computational analysis to answer questions about human mobility and translated the findings into anthropology based on a publicly available data set of road traffic counters in Slovenia. The analysis revealed insights about driving habits, tourism patterns, preferred locations, weekly and yearly variations, and outliers in road traffic. The study concluded that quantitative data analysis is a valuable tool for preliminary research in anthropology, but only partially answers anthropological questions.

Summary: Enzymes are increasingly being utilized as biocatalysts in various industries. The reliable annotation of enzyme catalytic function is crucial for expanding the range of available and useful biocatalysts. However, experimental characterization in the laboratory is necessary to confidently guarantee the quality of such annotation. This study presents a novel approach for the automatic selection of subsets from enzyme families, which outperforms other methods and demonstrates its effectiveness through experiments on three diverse enzyme families.
