Condensate protein aggregation in ALS/FTD is regulated by GGGGCC-repeat RNA scaffolds”

Protein aggregation driven by intrinsically disordered proteins is a hallmark of neurodegenerative diseases, yet remains challenging to therapeutically target. In ALS/FTD, GGGGCC repeat expansion in C9orf72 generates both toxic RNA foci and dipeptide repeat proteins such as poly(GR), but their cooperative role in pathological condensates has remained unclear.

Prof. HAN Da and Prof. GUO Pei demonstrated that GGGGCC-repeat RNA functions as a structural scaffold that promotes phase separation and aggregation of poly(GR) proteins. RNA G-quadruplex and hairpin structures were identified as critical regulators of condensate formation and maturation. Importantly, simultaneous targeting of these RNA structural elements significantly inhibited protein aggregation, revealing a cooperative RNA–protein pathogenic mechanism and expanding therapeutic strategies for neurodegenerative diseases.

De novo design of functional nucleic acids of aptamers”

Functional nucleic acids such as aptamers are traditionally discovered through SELEX-based experimental evolution, a process that is labor-intensive, time-consuming, and constrained by experimental bias.

Prof. HAN Da, Prof. CHEN Guangyong, Prof. GUO Pei, and Prof. QIU Jiezhong developed InstructNA, a generative AI framework for nucleic acid design. By integrating nucleotide language models, HT-SELEX datasets, and Bayesian optimization, the system enables efficient de novo generation of functional nucleic acids with improved activity and diversity. This work establishes a paradigm shift from experimental evolution to AI-driven molecular design.

Preclinical Characterization and Clinical Activity of RNK08954, a Highly Selective and Orally Bioavailable KRASG12D Inhibitor”

KRAS G12D is one of the most challenging oncogenic drivers in solid tumors due to the absence of suitable druggable binding pockets, representing a major unmet clinical need.

Prof. SONG Zhengbo and collaborators at RAINO Biopharma report RNK08954, a novel non-covalent, orally bioavailable, and highly selective KRASG12D inhibitor. The compound forms a high-affinity salt-bridge interaction with KRASG12D and effectively suppresses downstream MAPK and PI3K signaling pathways.

Preclinical studies demonstrate strong antitumor activity across CDX, PDX, and orthotopic models with favorable safety profiles. Early Phase I clinical results (NCT06667544) in 42 patients with KRAS-mutant solid tumors show encouraging safety and preliminary efficacy, supporting further clinical development.

Anti-PD-1 antibody penpulimab plus chemotherapy for recurrent or metastatic nasopharyngeal carcinoma: a randomized, double-blind phase 3 study”

Recurrent or metastatic nasopharyngeal carcinoma remains a clinically challenging disease with limited long-term therapeutic outcomes. Immunotherapy combined with chemotherapy has emerged as a promising treatment strategy, but optimization of efficacy and safety remains necessary.

Prof. CHEN Xiaozhong, Prof. HUANG Shuang, and collaborators conducted a multicenter Phase III randomized trial across 46 institutions evaluating penpulimab plus chemotherapy. The combination significantly improved median progression-free survival (9.63 vs. 7.00 months; HR 0.45, P < 0.0001), with consistent benefit across all predefined subgroups and a manageable safety profile, supporting its use as a first-line treatment option.

A DNA Origami-Based Cobweb Facilitates Precise and Receptor Interference Free Modification of Extracellular Vesicle Mimetic for Enhanced Delivery Efficacy”

Extracellular vesicle mimetics are promising drug delivery platforms due to their biocompatibility and natural biological origin. They are widely studied for therapeutic delivery applications. However, precise surface modification remains challenging because conventional approaches may disrupt native membrane proteins.

Prof. HAN Da and Prof. TANG Qian developed a DNA origami-based “cobweb” nanostructure that enables highly precise and receptor-interference-free surface modification. This strategy significantly enhances targeted delivery efficiency while preserving native membrane functionality.

DNA-Based FRET Nanoscopy Reveals Rapid CD45 Exclusion from Raft-like Domains upon T-Cell Receptor Signaling”

Membrane lipid domains are nanoscale and highly dynamic structures. These properties make it difficult to directly visualize protein redistribution during immune activation. This limitation has hindered detailed understanding of membrane-associated signaling events.

Prof. QIU Liping and colleagues developed a DNA-based FRET nanoscopy platform to monitor CD45 dynamics in living cells. They demonstrate that T-cell receptor activation triggers rapid exclusion of CD45 from raft-like domains through cytoskeletal and lipid remodeling, providing mechanistic insight into T-cell activation.

Chenodeoxycholic acid redirects the bile acid synthetic pathway to limit pro-inflammatory neutrophil infiltration and alleviate colitis”

Inflammatory bowel disease involves both metabolic dysregulation and immune imbalance. These processes contribute to chronic intestinal inflammation. The role of bile acid pathway remodeling in this process remains unclear.

Prof. HAN Weidong and colleagues show that chenodeoxycholic acid (CDCA) redirects bile acid synthesis toward alternative pathways, suppressing CXCL2-mediated neutrophil recruitment via VDR/NF-κB signaling and alleviating intestinal inflammation.
