RBM39 is an essential component of the spliceosome, playing a critical role in maintaining mRNA integrity. Its depletion significantly exacerbates RNA splicing defects and demonstrates potent anticancer activity. To identify key effectors following depletion, we employed multiomics approach to directly compare two structurally distinct compounds, CB039 Indisulam. Through proteomic analysis, sequencing, DepMap dependency assessment, CEP192 emerged as crucial gene, exhibiting 96% 1,100 analyzed cancer cell lines. In eight lines, treatment with both Indisulam consistently induced exon 42 skipping reduced protein levels. Mechanistically, either or interference-mediated knockdown led significant increase spindle disorganization, well chromosome condensation failed segregation. conclusion, our characterization downstream effects provides novel insights into therapeutic potential degraders.

Abstract Alternative splicing (AS) serves as a pivotal mechanism in transcriptional regulation, engendering transcript diversity, and modifications protein structure functionality. Across varying tissues, developmental stages, or under specific conditions, AS gives rise to distinct splice isoforms. This implies that these isoforms possess unique temporal spatial roles, thereby associating with standard biological activities diseases. Among these, AS-related RNA-binding proteins (RBPs) play an instrumental role regulating alternative events. Under physiological the diversity of mediated by influences structure, function, interaction, localization proteins, participating differentiation development array tissues organs. pathological alterations are linked various diseases, particularly cancer. These changes can lead gene patterns, culminating loss For instance, cancer, abnormalities RBPs may result aberrant expression cancer-associated genes, promoting onset progression tumors. also associated numerous neurodegenerative diseases autoimmune Consequently, study across different holds significant value. review provides detailed account recent advancements tissue which aids deepening understanding complexity offers new insights methodologies for precision medicine.

Aging is the biggest risk factor for development of Alzheimer's disease (AD). Here, we performed a whole-genome CRISPR screen to identify regulators neuronal age and show that neddylation pathway regulates both cellular AD neurodegeneration in human stem cell model. Specifically, demonstrate blocking increased hallmarks aging led an increase Tau aggregation phosphorylation neurons carrying APPswe/swe mutation. Aged but not isogenic control also showed progressive decrease viability. Selective loss upon inhibition was similarly observed other Parkinson's (PD) models, including PSENM146V/M146V cortical LRRK2G2019S/G2019S midbrain dopamine neurons, respectively. This study indicates can reveal late-onset phenotypes, identifies new potential targets modulate progression, describes strategy program age-associated phenotypes into models disease.

Abstract The human genome contains instructions to transcribe more than 200,000 RNAs. However, many RNA transcripts are generated from the same gene, resulting in alternative isoforms that highly similar and remain difficult quantify. To evaluate ability study transcript expression, we profiled seven cell lines with five different RNA-sequencing protocols, including short-read cDNA, Nanopore long-read direct RNA, amplification-free cDNA PCR-amplified sequencing, PacBio IsoSeq, multiple spike-in controls, additional transcriptome-wide N 6 -methyladenosine profiling data. We describe differences read length, coverage, throughput reporting sequencing robustly identifies major isoforms. illustrate value of SG-NEx data identify isoforms, novel transcripts, fusion modifications. Together, provide a comprehensive resource enabling development benchmarking computational methods for complex transcriptional events at isoform-level resolution.

Alzheimer’s disease (AD) is a complex multifactorial disorder that poses substantial burden on patients, caregivers, and society. Considering the increased aging population life expectancy, incidence of AD will continue to rise in following decades. However, molecular pathogenesis remains controversial, superior blood-based biomarker candidates for early diagnosis are still lacking, effective therapeutics halt or slow progression urgently needed. As powerful genetic regulators, microRNAs (miRNAs) receiving increasing attention due their implications initiation, development, theranostics various diseases, including AD. In this review, we summarize miRNAs directly target microtubule-associated protein tau (MAPT), amyloid precursor (APP), β-site APP-cleaving enzyme 1 (BACE1) transcripts regulate alternative splicing APP. We also discuss related kinases, such as glycogen synthase kinase (GSK)-3β, cyclin-dependent 5 (CDK5), death-associated (DAPK1), well apolipoprotein E, targeted by control phosphorylation amyloidogenic APP processing leading Aβ pathologies. Moreover, there evidence miRNA-mediated modulation inflammation.
