Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks

Advanced Science, EarlyView.
In this study, the orange‐muscle giant abalone (Haliotis gigantea) is used as a model to identify a non‐coding SNP that disrupts the interaction between ITGA8 pre‐mRNA and the splicing factor ILF2, leading to altered ITGA8 splicing. These splicing changes promote carotenoid accumulation in abalone muscle through the regulation of tissue remodeling ...

Dual Aptamers‐Based SETDB1 PROTACs as Effective Anti‐Tumor Strategies for Breast Cancer

Advanced Science, EarlyView.
This study establishes dual‐aptamer PROTACs targeting SETDB1 using a SETDB1‐specific aptamer conjugated to AS1411. The designed PROTACs penetrate cells, recruit MDM2 to degrade SETDB1, and inhibit cancer cell proliferation and migration. Remarkably, they also overcome tamoxifen resistance and enhance CD8+ T cell cytotoxicity, suppressing tumor growth ...

A TtAgo‐Driven Autocatalytic Circuit with Thermal‐Enhanced Kinetics for One‐Pot Nucleic Acid Detection

Advanced Science, EarlyView.
This study proposes a universal catalytic DNA circuits termed TACTIC (Thermus thermophilus protein‐driven autocatalytic circuit) for one‐pot detection of DNA and RNA in multiple clinical samples. Integrated with machine learning, TACTIC accurately profile the distinct expression of four extracellular vesicle‐derived miRNAs across different samples and ...

Putative DNA G-quadruplex formation within the promoters of Plasmodium falciparum var genes

BMC Genomics, 2009
Background Guanine-rich nucleic acid sequences are capable of folding into an intramolecular four-stranded structure called a G-quadruplex. When found in gene promoter regions, G-quadruplexes can downregulate gene expression, possibly by blocking the ...

Mucin Glycoprotein Nanoparticles Enable a Selective Antisense Therapy for Oncogenic MicroRNAs

Advanced NanoBiomed Research, EarlyView.
Mucin glycoproteins are turned into nanoparticles by employing synthetic DNA strands, which have a dual function: they stabilize the nanoparticles and act as binding sites for intracellular miRNA‐21. Thus, upon internalization into tumor cells, these mucin nanoparticles can deplete miRNA‐21 from the cytosol, which induces apoptosis in vitro and in vivo.
