A team of researchers has identified a mechanism that interferes with the splicing process in a more subtle way, leading to cell death. The study reveals that spliceosome subunits U4, U5, and U6 are normally stabilized by protein USP39, but when mutated or absent, stability is compromised, causing incorrect connections during splicing.
Researchers discovered that hnRNPM prevents errors in protein synthesis by blocking pseudo splice sites, maintaining accurate mRNA molecules. In its absence, cancer cells exhibit increased cryptic splicing, triggering interferon immune responses and potentially driving disease progression.
A novel mechanism for splicing human short introns has been discovered using the SAP30BP-RBM17 complex. The researchers confirmed that the established pre-mRNA splicing mechanism cannot work in a subset of human short introns.
Researchers have identified three novel pathogenic variants of the ATR gene as predisposing to male breast cancer. These variants were found in a cohort of individuals with early onset and familial breast cancers, using a combination of exome sequencing and functional investigations. The study suggests that extended genetic analysis ca...
Researchers at Children's Hospital of Philadelphia developed ESPRESSO, a new computational tool that can accurately discover and quantify RNA molecules from error-prone long-read RNA sequencing data. This will enable better diagnosis of rare genetic diseases and discovery of potential therapeutic targets in cancer.
Researchers from Tokyo Medical and Dental University have developed a new approach to analyze splicing variant data to identify disease-associated genetic variations. The study reveals that analyzing the coding sequences of gene splicing variants can help uncover the genetic basis of many diseases.
Splicing errors can lead to faulty proteins, increasing disease risk. Researchers analyzed 32,000 DNA sequences to understand the rules guiding RNA processing and improve predictions of genetic mutations' impact on disease risk.
Researchers at Brown University discovered over 800 tiny genetic loops, called lariats, in human tissues, providing new insights into RNA splicing decisions. The location of branchpoints on these lariats reliably predicts where splicing will occur, enabling the creation of an algorithmic model with 95.6% accuracy.
A Cold Spring Harbor Laboratory study reveals a new way in which the cell's splicing machinery recognizes splice sites, impacting current ideas on how missteps triggered by mutations can lead to diseases. The discovery affects up to 5% of all splice sites and has implications for pinpointing splicing defects underlying certain diseases.
A new web-based program called Spliceman predicts whether genetic mutations will disrupt mRNA splicing, a process crucial for gene expression. The software uses research to show that many disease-causing mutations occur due to faulty splicing instructions.
Researchers discovered that U1, a guiding RNA molecule, can 'slide' one base to recognize atypical splice sites, explaining the genetic error in PCH. This shift enables U1 to form stronger matches with divergent sequences.
The study reveals that small changes in nucleotide sequences near splice points can lead to significant changes in splice site choice and protein production. The discovery suggests that curing most genetic diseases will take longer than expected due to the complexity of alternative splicing mechanisms.
Researchers found that low temperatures trigger a specific splicing mechanism in frq mRNA, excluding the l-FRQ translation initiation site and modulating circadian rhythmicity. This temperature-dependent inhibition of translation by uORFs effectively regulates FRQ levels and circadian rhythms.
Researchers develop novel approach to treat thalassemias by blocking aberrant RNA splicing. The new virus effectively repairs existing RNA, restoring correct hemoglobin production and offering a lifeline for patients.
