PTBP1‐Mediated Alternative Splicing of DNAJB6 Promotes Everolimus Resistance in Clear Cell Renal Cell Carcinoma via EIF4B/PKIB/AKT/mTOR Positive Feedback Loop

Advanced Science, EarlyView.
PTBP1‐mediated alternative splicing drives a pathogenic switch to the DNAJB6b isoform in everolimus‐resistant clear cell renal cell carcinoma. This splicing event programs a positive feedback loop including EIF4B/PKIB/AKT/mTOR, promoting aggressive therapy resistance.

CHD8‐Dependent Chromatin Licensing Sustains Trophoblast Stem Cell Transcriptional Programs

Advanced Science, EarlyView.
In this study, Huang et al., identify chromatin remodeler CHD8 as an essential factor in TSC maintenance and placental development. CHD8‐dependent chromatin accessibility supports the occupancy of key trophoblast TFs and is coupled to KMT2A‐associated H3K4me3 deposition at TSC stem and cell cycle genes, providing a permissive chromatin environment for ...

Granzyme B PET Imaging Reveals Lgmn+ Macrophage‐Mediated Immune Evasion and Guides Immunotherapy in EGFR‐TKI‐Resistant NSCLC

Advanced Science, EarlyView.
Graphical illustration of 68Ga‐GZB PET/CT imaging reveals immune dynamics post‐EGFR‐TKI resistance in NSCLC; Lgmn+ macrophages‐derived Lgmn‐containing extracellular vesicles inhibit glycolysis, induce CD8+ T cell exhaustion, and targeting Lgmn restores immunotherapy sensitivity.
