In Vivo CRISPR Screen Identifies RPS19 as an Immunotherapy Target in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
By employing in vivo CRISPR functional screening, we identify ribosomal protein RPS19 as a pivotal mediator driving immune evasion in hepatocellular carcinoma, wherein tumor‑released RPS19 binds C5aR1 on tumor‑associated macrophages to initiate downstream immunosuppressive signaling; SP94‑peptide‑modified SNPSS nanoparticles deliver Cas9/sgRPS19 ...

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

DNA sequencing analysis of ITS and 28S rRNA of Poria cocos

open access: yesDNA sequencing analysis of ITS and 28S rRNA of Poria cocos
We determined the DNA sequences of the internal transcribed spacer 1 and 2 (ITS 1 and 2), the 5.8S rRNA gene and most of the 28S rRNA gene of Poria cocos for the first time, and conducted analysis of 20 samples including cultured mycelias and crude drug materials obtained from various localities and markets. Direct sequencing of the ITS 1 and 2 regions

The Interplay Between Molybdopterin Synthase and Metal Metabolism Contributes to Pathogenicity in Acinetobacter baumannii

open access: yesAdvanced Science, EarlyView.
Pathogenic Acinetobacter baumannii scavenges metal ions as nutritional elements to survive within the host. This study demonstrates that molybdopterin synthase is essential for pathogenesis and full virulence during infection. Molybdopterin synthase subunit MoaE constitutes an intrinsically disordered C‐terminal histidine rich tail, which mediates ...

Nanocatalytic Immunotherapy Targeting Tumor‐Resident Intracellular Bacteria for Triple‐Negative Breast Cancer Treatment and Metastasis Suppression

open access: yesAdvanced Science, EarlyView.
Bacteria residing within tumor cells contribute to breast cancer progression, but few therapies target their elimination. FeSe2 nanosheets coated with cancer cell membranes accumulate in tumors and generate reactive oxygen species under ultrasound, killing tumor cells and their harbored bacteria at the same time.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

open access: yesAngewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Small Intestinal Bacterial Overgrowth Following Gastrointestinal Cancer Surgery: Current Evidence and Future Perspectives

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Small intestinal bacterial overgrowth (SIBO) has recently gained increasing attention as a potential cause of postoperative gastrointestinal symptoms following gastrointestinal cancer surgery. Surgical procedures can disrupt normal gastrointestinal physiology through anatomical reconstruction, impaired motility, reduced gastric acid secretion,

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

open access: yesAngewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.
