Placental Site Trophoblastic Tumor Acquires Immune Functions by Incorporating Host Maternal Genes

Advanced Science, EarlyView.
PSTT cells, through cell fusion with B cells, incorporate abundant non‐inherited maternal genes that are detectable by DNIMA. These hybrid cells acquire immunotherapy‐resistant genetic changes and increase the expression of B cell‐derived immune‐related molecules such as Ig, HLA, LILRB, SIGLEC10, and so on, creating an immunotolerant environment around

Single‐Molecule Characterization of Bacterial Factor‐Dependent Transcription Activation by Rob

Advanced Science, EarlyView.
Factor‐dependent transcription activation is crucial and involves complex interactions between transcription factors, RNA polymerase, and promoter DNA. Using single‐molecule assays, we show that Rob prebinds RNAP to facilitate promoter search and enhances DNA unwinding and promoter escape.

The possible regulatory role of miR-4463 and its target gene CYP19A1 on the ovarian response in the women with diminished ovarian reserve: A case-control study

International Journal of Reproductive BioMedicine
Background: Diminished ovarian reserve (DOR) is a condition that affects fertility by reducing the reproductive potential of the ovary. The altered expression profile of cumulus cells (CCs) can negatively affect the quality and quantity of oocytes in the

Meiotic gene expression of STAG3 and DMC1 in blood: A novel non-invasive biomarker approach for diminished ovarian reserve: A case-control study

International Journal of Reproductive BioMedicine
Background: Diminished ovarian reserve (DOR) is a major cause of female infertility, marked by reduced oocyte quantity and quality. STAG3 and DMC1 are meiosis-specific genes essential for chromosomal integrity and homologous recombination.

Multiscale Spatial Fusion Feature‐Driven Characterization of Gastric Cancer Invasive Margins: A Multicenter Cohort Study for Preoperative Accurate Differentiation Between T4a and T4b Subtypes

Advanced Science, EarlyView.
This study develops a multi‐dimensional vision Transformer‐based model, GAVR, to accurately distinguish gastric cancer T4a/b stages preoperatively. Validated across multi‐center cohorts, it achieves excellent performance and significantly improves radiologists’ diagnostic accuracy, offering a promising tool for clinical decision‐making.

Integrated Single‐Cell and TCR Profiling Reveals Protection‐Associated CD8+ T Cell Subsets Linked to Viral Control in PRRSV

Advanced Science, EarlyView.
PRRSV vaccine‐mediated protection is associated with clonally expanded cytotoxic CD8+ T cell subsets driven by viral structural proteins and supported by innate TLR4/TLR8 signaling and CD4+ T cell help, whereas non‐protective responses are characterized by dysfunctional exhausted‐like CD8+ T cells linked to poor viral control.

Human Foetal Neuroblasts Exhibit BK Channel‐Dependent Membrane Voltage Oscillations upon Depolarization

Advanced Science, EarlyView.
Primary cultures of neuroblasts isolated from the nucleus basalis of Meynert of 12‐weeks‐old human foetuses were prepared. Whole‐cell patch‐clamp recordings were performed by injecting a depolarizing stimulus current (+500 pA; 500 ms), and the membrane voltage recorded; this stimulus current evoked periodic‐like oscillations in membrane voltage ...
