Meta-analysis of breast cancer microarray studies in conjunction with conserved cis-elements suggest patterns for coordinate regulation

open access: yesBMC Bioinformatics, 2008
Background Gene expression measurements from breast cancer (BrCa) tumors are established clinical predictive tools to identify tumor subtypes, identify patients showing poor/good prognosis, and identify patients likely to have disease recurrence. However,

Quantitative Assessment of Randomized DNA Base Sequences Using Multi‐Model Physical Analysis for High‐Fidelity Data Storage

open access: yesAdvanced Science, EarlyView.
This study quantitatively evaluates randomized DNA sequence design for digital data storage using three physics‐based models. By applying encoding schemes with strict homopolymer constraints, the framework improves base randomness, GC balance, and error resilience. Experimental validation via PCR and Sanger sequencing confirms 95–98% decoding accuracy,

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 ...

Software and methods for oligonucleotide and cDNA array data analysis. [PDF]

open access: yes, 2002
Two HTML-based programs were developed to analyze and filter gene-expression data: 'Bullfrog' for Affymetrix oligonucleotide arrays and 'Spot' for custom cDNA arrays. The programs provide intuitive data-filtering tools through an easy-to-use interface. A

MARPLE: A Proximity‐Triggered CRISPR‐Cas13 Platform for Ultrasensitive Antibody Detection

open access: yesAdvanced Science, EarlyView.
MARPLE is a modular CRISPR‐Cas13 immunoassay that uses antibody‐induced proximity to trigger a toehold‐exchange reaction, releasing an RNA activator for Cas13. This one‐pot, isothermal architecture enables ultrasensitive (femtomolar) and highly specific detection of diverse antibodies, including therapeutic, pathogen‐specific, and cancer‐associated ...

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.

Nanozymes Integrated Biochips Toward Smart Detection System

open access: yesAdvanced Science, EarlyView.
This review systematically outlines the integration of nanozymes, biochips, and artificial intelligence (AI) for intelligent biosensing. It details how their convergence enhances signal amplification, enables portable detection, and improves data interpretation.

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.

A Sirtuin‐1‐Targeted Gene‐Activating Tetrahedral DNA Attenuates Bladder Fibrosis by Restoring Mitophagy in Fibroblasts via the SIRT1‐FOXO3‐BNIP3 Axis

open access: yesAdvanced Science, EarlyView.
The SIRT1‐targeted saRNA‐delivering tetrahedral DNA (TSA) treatment effectively upregulates SIRT1 expression, which subsequently promotes FOXO3A deacetylation. This deacetylation event relieves FOXO3A's transcriptional repression on the BNIP3 gene, thereby initiating PINK1‐PARKIN‐dependent mitophagy.
