• REV1–DHX36 Control of G4 DNA Replication

  2026-08-28

  The 2026 Nucleic Acids Research study identifies a direct REV1–DHX36 interaction that coordinates G-quadruplex unwinding, replication-fork progression, and suppression of single-stranded DNA gaps. Its two-tiered model clarifies how cells tolerate stabilized G4 structures and provides a mechanistic framework for studying replication stress and DNA damage response signaling.

• Olaparib Nanoparticles for Local Brain Tumor Delivery

  2026-08-28

  The reference study developed a sprayable pectin hydrogel containing PLA-PEG-coated etoposide and olaparib nanocrystals for local delivery after brain-tumor resection. Its findings support a preclinical formulation strategy that combines bioadhesion, sustained drug release, and nanoparticle distribution around a surgical cavity, while stopping short of demonstrating therapeutic efficacy in intracranial tumor models.

  2026-08-27

  Turn DNA-PK inhibition into a controlled workflow for DNA repair research, oncology research, and cell-cycle analysis. This guide connects cancer-cell sensitization assays with a carefully bounded, hypothesis-generating approach to cytosolic-DNA and TDP-43 biology.

• iPSC Platform for Ultrarare Disease Trial Selection

  2026-08-26

  Sequiera et al. developed a patient-specific iPSC platform to prescreen therapies for an ultrarare ECHS1-related Leigh-like syndrome before clinical trial participation. The study shows how disease-relevant cellular models can connect molecular diagnosis, drug response, and longer-term clinical decision-making while also defining important limits for generalization.

• Linoleic Acid: From Membranes to Metabolic Signals

  2026-08-26

  Explore how Linoleic Acid (C18:2(9Z,12Z)) connects membrane behavior, redox biology, and selective translation. This article turns recent fasting research into a practical framework for choosing interpretable cell and erythrocyte assays.

• IR-1061 Near Infrared Fluorescent Dye Workflow

  2026-08-25

  IR-1061 supports OTN-NIR imaging workflows that prioritize deep-tissue contrast, but its hydrophobicity makes formulation design essential. This guide translates polymer-encapsulation findings into practical preparation, assay, optimization, and troubleshooting decisions for biomedical imaging researchers.

• Protease Inhibitor Cocktail EDTA-Free: K1010 Guide

  2026-08-25

  The Protease Inhibitor Cocktail is a 100X DMSO formulation for limiting endogenous proteolysis during protein extraction. Its EDTA-free design supports workflows that require divalent cations, including phosphorylation analysis and selected kinase assays.

• Olaparib and SmD2: Rethinking HCC PARP Assays

  2026-08-24

  Olaparib and AZD2281 provide a precise way to interrogate PARP-dependent DNA repair in hepatocellular carcinoma. This article explains how SmD2-regulated splicing can refine DNA damage response assays, biomarker interpretation, and combination-study design beyond conventional BRCA-based models.

• Sulfo-NHS-SS-Biotin: Cleavable Labeling Guide

  2026-08-24

  Sulfo-NHS-SS-Biotin provides water-compatible, amine-selective biotinylation for protein capture, detection, and reversible affinity workflows. It is suitable for intact-cell surface labeling and purified protein conjugation, but not for intracellular labeling or assays that require a permanently attached biotin tag.

• ABT-263: From Apoptotic Priming to Translation

  2026-08-23

  ABT-263 (Navitoclax) is more than a cytotoxicity reagent: it is a mechanistic probe for Bcl-2-family dependence, mitochondrial priming, and the selective elimination of chemotherapy-induced senescent cancer cells.
