A Comparative Study of Methyl-BEAMing and Droplet Digital PCR for MGMT Gene Promoter Hypermethylation Detection

Diagnostics
Background: O-6-methylguanine-DNA methyltransferase is responsible for the direct repair of O6-methylguanine lesions induced by alkylating agents, including temozolomide.

HMGB2–RAD21 Axis Promotes Fibro/Adipogenic Progenitor Proliferation and Regulates Fat Infiltration

Advanced Science, EarlyView.
This study constructed the first developmental atlas of embryonic skeletal muscle fibro/adipogenic progenitors (FAPs) and identified an HMGB2+ FAPs subpopulation that regulates FAP pool size and muscle homeostasis. HMGB2 directly targets the RAD21 promoter, and its knockout significantly reduces FAP numbers, thereby lowering the potential for ...

Stimuli‐Responsive Supramolecular Biomaterials for Cancer Theranostics

Advanced Science, EarlyView.
The ultimate goal of cancer theranostics is to get imaging agents and therapeutic cargo to tumor sites when and where they are required. “Smart” systems should be developed. This review discusses the characteristics of physiological stimuli, types and action modes of external stimuli, construction approaches and working principles, as well as ...

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Engineering Compact Base Editors by AlphaFold‐Guided Mutation Scan and Escherichia coli‐Based Tri‐Selection

Advanced Science, EarlyView.
A miniaturized deaminase SsdAtox was scanned with AlphaFold to identify DNA binding pocket hot spots. Site‐saturation mutagenesis at gatekeeper residue K31 yielded ten‐fold activity enhancement. Trinity Screen, an E. coli‐based three‐in‐one platform selecting for high activity and reduced double‐strand breaks, enabled combinatorial evolution at DNA ...

Structure‐Guided Engineering of a Cas12i Nuclease Unlocks Near‐PAMless Genome Editing

Advanced Science, EarlyView.
CRISPR‐Cas nucleases are limited by PAM requirements, restricting genome accessibility. Structure‐guided engineering of the compact Cas12i nuclease SF01 produced three variants with near‐PAMless, enabling efficient editing at diverse 5'‐NNTN‐3' sites. These nucleases expand the editable portion of the human genome more than fourfold, enabling efficient

A Modular DNAzyme for Precise Visualization and Intervention of Alternative Splicing Isoforms in Live Cells

Advanced Science, EarlyView.
A Stringent dUPlex‐activated Error Robust (SUPER) DNAzyme system enables real‐time imaging of alternative mRNA splicing (e.g., Bcl‐xL/Bcl‐xS) in living cells via target‐triggered split‐DNAzyme reassembly and dual‐color fluorescence. It also achieves mRNA‐selective knockdown through DNAzyme‐based gene regulation, serving as a versatile tool for splicing

NIR Light‐Driven Photocatalytic Antibacterial Hydrogels for Synergistic MRSA Biofilm Eradication and Wound Regeneration

Advanced Science, EarlyView.
The nanohybrid hydrogel (Fe‐BOS@C/H Gel) is composed of Fe‐Bi2O2‐XS (Fe‐BOS) photocatalysts and CS‐ADH/OHA (C/H) hydrogel. Fe‐BOS photocatalysts achieve near‐infrared (NIR) light‐driven antibacterial photocatalytic/mild photothermal therapy (APCT/MPTT), effectively eliminating methicillin‐resistant Staphylococcus aureus (MRSA) biofilms. The degradation
