Among these insertions, retrotransposable elements (REs) and host genomic coding and regulatory sequences are prevalent.

Highly Efficient and Stable CsPbI Perovskite Quantum Dots Light-Emitting Diodes Through Synergistic Effect of Halide-Rich Modulation and Lattice Repair.

Currently, CsPbI quantum dots (QDs) based light-emitting diodes (LEDs) are not well suited for achieving high efficiency and operational stability due to the binary-precursor method and purification process, which often results in the nonstoichiometric ratio of Cs/Pb/I. This imbalance leads to amounts of iodine vacancies, inducing severe non-radiative recombination processes and phase transitions of QDs. Herein, red-emitting CsPbI QDs are reported with excellent optoelectronic properties and stability based on the synergistic effects of halide-rich modulation passivation and lattice repair.

Successful classification of clinical pediatric leukemia genetic subtypes via structural variant detection using HiFi long-read sequencing.

Gene fusions are common primary drivers of pediatric leukemias and are the result of underlying structural variant (SVs). Current clinical workflows to detect such alterations rely on a multimodal approach, which often increases analysis time and overall cost of testing. In this study, we used long-read sequencing (lrSeq) as a proof-of-concept to determine whether clinically relevant (cr) SVs could be detected within a small (n = 17) pediatric leukemia cohort.

Self-Adaptive Dielectrics with Tunable Nonlinear Electrical Conductivity via Virus-Like Structures Composed of Metal Particles.

Self-adaptive dielectrics (SADs), with the characteristics of rapid charge dissipation in electric field distortion, is regarded as the future material for package insulation of advanced electronic devices. The current landscape of SADs is incapable to achieve tunable nonlinear electrical conductivity and threshold field strength due to the inherent Schottky barrier, significantly limiting the application scenarios of SADs. Here, a strategy is reported to construct a stepped Schottky barrier through virus-like structures, which are composed of subminiature metal particles and semiconductor microspheres.

Ensemble learning-based predictor for driver synonymous mutation with sequence representation.

Synonymous mutations, once considered neutral, are now understood to have significant implications for a variety of diseases, particularly cancer. It is indispensable to identify these driver synonymous mutations in human cancers, yet current methods are constrained by data limitations. In this study, we initially investigate the impact of sequence-based features, including DNA shape, physicochemical properties and one-hot encoding of nucleotides, and deep learning-derived features from pre-trained chemical molecule language models based on BERT.

Mismatch prime editing gRNA increased efficiency and reduced indels.

Prime editing enables precise and efficient genome editing, but its efficacy is hindered by pegRNA's 3' extension, forming secondary structures due to high complementarity with the protospacer. The continuous presence of the prime editing system also leads to unintended indel formation, raising safety concerns for therapeutic applications. To address these challenges, we develop a mismatched pegRNA (mpegRNA) strategy that introduces mismatched bases into the pegRNA protospacer, reducing complementarity and secondary structure formation, and preventing sustained activity.

Downregulation of the splicing regulator NSRP1 confers resistance to CDK4/6 inhibitors via activation of interferon signaling in breast cancer.

The combination of CDK4/6 inhibitors (CDK4/6i) and endocrine therapy is the first-line therapy for ER+/Her2-breast cancer; however, the development of drug resistance limited the efficacy of the agents. Although activation of the IFN signaling pathway has been identified as a critical driver of intrinsic and acquired CDK4/6i resistance, it remains unknown how the IFN signaling pathway was activated in resistant cells. Here, we report that NSRP1, a regulator of alternative mRNA splicing is downregulated in CDK4/6i resistant breast cancer cells and contributes to CDK4/6i resistance by mediating alternative splicing of NSD2 mRNA and activation of the IFN signaling pathway.
