Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Alternative mapping of probes to genes for Affymetrix chips

BMC Bioinformatics, 2004
Background Short oligonucleotide arrays have several probes measuring the expression level of each target transcript. Therefore the selection of probes is a key component for the quality of measurements.

Strawberry Notch 1 Acts as a Transcriptional Regulator Driving Oncogenic Programs in Liver Carcinogenesis

Advanced Science, EarlyView.
This study reports that SBNO1 protein is upregulated in several cancer entities. SBNO1 protein interacts with the basal transcription factor TFIID via TAF4, enabling its recruitment to transcription start sites and the modulation of target gene expression.

Mammalian Proteome Profiling Reveals Readers and Antireaders of Strand‐Symmetric and ‐Asymmetric 5‐Hydroxymethylcytosine‐Modifications in DNA

Advanced Science, EarlyView.
We investigate by proteomics studies how strand‐symmetric and ‐asymmetric cytosine 5‐modifications in DNA are selectively recognized by the nuclear proteome. Using promoter probes with defined modification patterns, we identify tissue‐specific reader proteinsincluding MYC, MAX, and RFX5that discriminate 5‐hydroxymethylcytosine symmetry and sequence ...

Improved detection of global copy number variation using high density, non-polymorphic oligonucleotide probes

BMC Genetics, 2008
Background DNA sequence diversity within the human genome may be more greatly affected by copy number variations (CNVs) than single nucleotide polymorphisms (SNPs).

Selective Targeting of Tip Endothelial Cells as a Therapeutic Strategy for Tumor Angiogenesis

Advanced Science, EarlyView.
Doppel protein is selectively expressed in tip endothelial cells within the tumor vasculature, where it promotes tip cell motility and stabilizes the tip cell phenotype. Targeting Doppel with monoclonal antibodies disrupts this stabilization, impairs angiogenic sprouting, and reduces tumor angiogenesis, offering a selective and druggable switch for ...

In vivo transcriptional profiling of Plasmodium falciparum

Malaria Journal, 2004
Background Both host and pathogen factors contribute to disease outcome in Plasmodium falciparum infection. The feasibility of studying the P. falciparum in vivo transcriptome to understand parasite transcriptional response while it resides in the human ...

Learned Conformational Space and Pharmacophore Into Molecular Foundational Model

Advanced Science, EarlyView.
The Ouroboros model introduces two orthogonal modules within a unified framework that independently learn molecular representations and generate chemical structures. This design enables flexible optimization strategies for each module and faithful structure reconstruction without prompts or noise.

Design and Characterization of DX‐Tile DNA Nanostar‐Based Hydrogels

Advanced Science, EarlyView.
In this study, the authors demonstrated that DNA DX‐tile‐based multi‐arm motifs can be used to assemble pure DNA hydrogels, offering greater design flexibility and enhanced control over their mechanical properties and functionalization capabilities compared to single duplex‐based DNA hydrogels.

Identification of a deep intronic mutation in the COL6A2 gene by a novel custom oligonucleotide CGH array designed to explore allelic and genetic heterogeneity in collagen VI-related myopathies

BMC Medical Genetics, 2010
Background Molecular characterization of collagen-VI related myopathies currently relies on standard sequencing, which yields a detection rate approximating 75-79% in Ullrich congenital muscular dystrophy (UCMD) and 60-65% in Bethlem myopathy (BM ...
