Thymidine-Inosine Dimer Building Block for Reversible Modification of Synthetic Oligonucleotides

Molecules
Modification of synthetic oligonucleotides and DNA is widely used in many applications in the life sciences. However, in most cases, modified DNA cannot be restored to its native state.

An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

Advanced Science, EarlyView.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

A Bioinspired Three‐Dimensional High‐Curvature Nano‐Interface Integrated Microfluidic Chip for Small Extracellular Vesicles Enrichment and Machine Learning‐Assisted Prostate Cancer Precision Diagnosis

Advanced Science, EarlyView.
A biotin‐modified artificial insertion peptide functionalized three‐dimensional high‐curvature‐TiO2 nano‐interface was engineered in a microfluidic chip to improve the isolation efficiency of small extracellular vesicles (sEVs). This chip balanced affinity, releasability, and extendibility, enabling high‐throughput recovery of sEVs for downstream ...

DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics

Advanced Science, EarlyView.
This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

The BnTFL1‐BnJAM3‐BnSWEETs Module Orchestrates Seed Storage Reserve Accumulation in Brassica napus

Advanced Science, EarlyView.
BnaC03.TFL1 and BnaA01.JAM3 form a complex that facilitates the transport of soluble sugars from the seed coat to the embryo by directly activating the expression of BnSWEETs. Furthermore, BnaC03.TFL1 and BnaA01.JAM3 work cooperatively to promote soluble sugar and oil production while suppressing protein deposition.

Disruption of the SNRPF–DDX24–E2F4 Feedback Loop Uncouples Splicing and Transcriptional Regulation to Suppress Ovarian Cancer Progression

Advanced Science, EarlyView.
This study identifies SNRPF as a critical oncogenic driver in ovarian cancer. By regulating a self‐sustaining SNRPF–DDX24–E2F4 feedback loop through intron retention and nonsense‐mediated decay, SNRPF couples RNA splicing with transcriptional regulation to promote tumor progression.
