Oligonucleotides blocking glucosylceramide synthase expression selectively reverse drug resistance in cancer cells

Journal of Lipid Research, 2004
High glucosylceramide synthase (GCS) activity is one factor contributing to multidrug resistance (MDR) in breast cancer. Enforced GCS overexpression has been shown to disrupt ceramide-induced apoptosis and to confer resistance to doxorubicin.

Syntheses and characterizations of the in vivo replicative bypass and mutagenic properties of the minor-groove O2-alkylthymidine lesions. [PDF]

, 2014
Endogenous metabolism, environmental exposure, and treatment with some chemotherapeutic agents can all give rise to DNA alkylation, which can occur on the phosphate backbone as well as the ring nitrogen or exocyclic nitrogen and oxygen atoms of ...

Nucleic acid - protein fingerprints. Novel protein classification based on nucleic acid - protein recognition [PDF]

, 2012
Protein chemistry uses protein description and classification based on molecular mass and isoelectric point as general features. Enzymes are also compared by enzymatic reaction constants, namely Km and kcat values. Proteins are also studied by binding to

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, Volume 36, Issue 33, 23 April 2026.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Biophysical and biological properties of quadruplex oligodeoxyribonucleotides [PDF]

Nucleic Acids Research, 2003
Single-stranded guanosine-rich oligodeoxyribonucleotides (GROs) have a propensity to form quadruplex structures that are stabilized by G-quartets. In addition to intense speculation about the role of G-quartet formation in vivo, there is considerable interest in the therapeutic potential of quadruplex oligonucleotides as aptamers or non-antisense ...

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

Novel Cell type-specific aptamer-siRNA delivery system for HIV-1 therapy [PDF]

, 2007
The successful use of small interfering RNAs (siRNAs) for therapeutic purposes requires safe and efficient delivery to specific cells and tissues. Here we demonstrate cell type-specific delivery of anti-HIV siRNAs via fusion to an anti-gp120 aptamer. The
