Modulating a Massive Set of Biomolecular Structures by Sono‐Mechanical Force

open access: yesAdvanced Science, EarlyView.
Using low‐power ultrasound exposure, picoNewton forces are generated to release loaded drugs after unfolding secondary structures in DNA nanoassemblies. This opens a door to reversibly manipulate a large set of biomolecular structures both inside and outside cells without the damages incurred by high‐power sonications currently used in the field ...

Mitochondrial DNA mutations in preneoplastic lesions of the gastrointestinal tract: A biomarker for the early detection of cancer

open access: yesMolecular Cancer, 2006
Background Somatic mutations of mitochondrial DNA (mtDNA) are common in many human cancers. We have described an oligonucleotide microarray ("MitoChip") for rapid sequencing of the entire mitochondrial genome (Zhou et al, J Mol Diagn 2006), facilitating ...

Red Blood Cell‐Derived Exosomal miR‐93‐5p Promotes Lung Cancer Progression through PTEN Suppression

open access: yesAdvanced Science, EarlyView.
Red blood cell (RBC)‐derived exosomal miR‐93‐5p is elevated in lung cancer patients and correlates with poor outcomes. Exosomal miR‐93‐5p suppresses PTEN in cancer cells, enhancing proliferation, migration, and invasion. In mouse models, therapeutic inhibition with ASO‐miR‐93 5p reduces tumor growth, highlighting a bidirectional tumor‐RBC‐tumor axis ...

Translation‐Promoting Effects of RNA Template Overhangs in the Absence of Ribosomes

open access: yesAngewandte Chemie, EarlyView.
Ribosome‐free translation of an RNA sequence into a peptide sequence can be controlled by the folding of the template strand. Overhang sequences forming a triplex structure with the templating region and the peptidoyl RNA in pH‐dependent manner increase yields up to 40‐fold through entropic effects and mixed anhydride formation, allowing for controlled,

MIMAS 3.0 is a Multiomics Information Management and Annotation System

open access: yesBMC Bioinformatics, 2009
Background DNA sequence integrity, mRNA concentrations and protein-DNA interactions have been subject to genome-wide analyses based on microarrays with ever increasing efficiency and reliability over the past fifteen years.

A Genome-Wide Analysis Reveals Significant Overlap of Transcription and DNA Repair in Stationary Phase Yeast [PDF]

open access: yes, 2008
The association between transcription and DNA repair is acknowledged as a player in the generation of mutations in a non-random fashion in prokaryotes and eukaryotes.

A Pan‐TE Map Reveals the Important Role of Transposable Elements in Gene Expression and Phenotypic Diversity in 2,311 Rapeseed Accessions

open access: yesAdvanced Science, EarlyView.
This study presents the first pan‐transposable element (TE) atlas in rapeseed, profiling over 8 million TEs across 2311 accessions. Integrative analyses reveal that TEs broadly shape gene expression through diverse regulatory mechanisms, with key insertions in BnaA03.FLC and BnaA09.CYP78A9 linked to flowering time and silique development.

Genome-wide mapping of ORC and Mcm2p binding sites on tiling arrays and identification of essential ARS consensus sequences in S. cerevisiae

open access: yesBMC Genomics, 2006
Background Eukaryotic replication origins exhibit different initiation efficiencies and activation times within S-phase. Although local chromatin structure and function influences origin activity, the exact mechanisms remain poorly understood.

Polymerase-endonuclease amplification reaction for large-scale enzymatic production of antisense oligonucleotide [PDF]

open access: yes, 2009
Synthetic oligonucleotides are contaminated with highly homologous failure sequences. Oligonucleotide synthesis is difficult to scale up because it requires expensive equipments, hazardous chemicals, and tedious purification process.

GLUL Confers Perivascular Cancer‐Associated Fibroblasts With Pro‐Angiogenic Capacity to Promote Glioma Progression

open access: yesAdvanced Science, EarlyView.
Schematic illustration of the proposed model. Primary CAFs are isolated from fresh human GBM specimens according to established protocols. GLUL is essential for pro‐angiogenic capacity of CAFs through its impact on the PI3K/AKT pathway. GLUL enhances the pro‐angiogenic capacity of CAFs, driving aberrant tumor vasculature that fuels tumor growth ...
