EX 527 in SIRT1-Dependent Bone Assays
2026-10-01
EX 527 (SEN0014196) provides a selective pharmacological test of whether SIRT1 catalytic activity is required for endothelial, osteogenic, and p53-linked phenotypes. This workflow connects biochemical target engagement with vascular–bone co-culture assays while separating pathway effects from solvent toxicity and nonspecific loss of cell fitness.

Patient-Derived Gastric Cancer Assembloids
2026-09-30
Shapira-Netanelov and colleagues developed patient-derived gastric cancer assembloids that combine matched tumor organoids with stromal subpopulations from the same tumor. The model reproduced tumor-associated heterogeneity and revealed that stromal composition can alter transcriptional programs and drug sensitivity, supporting more physiologically relevant cancer biology research.

Paeoniflorigenone Targets HIF1A in Cholangiocarcinoma
2026-09-29
This study identifies HIF1A as a central mediator of paeoniflorigenone activity in cholangiocarcinoma and reports enhanced antitumor effects when paeoniflorigenone is combined with cisplatin. Its combination of network pharmacology, computational structural analysis, cellular validation, and in vivo treatment testing provides a useful framework for evaluating natural-product chemosensitizers, while leaving pharmacokinetic and clinical questions unresolved.

Dynamic LRIG1 Expression in Salivary Gland Development
2026-09-28
Liu and colleagues combine single-cell RNA sequencing with histological and in vitro analyses to map changing LRIG1 expression during murine submandibular gland development. The study positions LRIG1 as a context-dependent marker and potential regulator of epithelial progenitor compartments while also identifying important limits for interpreting transcriptional, spatial, and cell-line data.

CCR7–Notch1 Crosstalk Promotes Mammary Cancer Stemness
2026-09-28
Boyle et al. show that CCR7 signaling and Notch1 activity functionally intersect to support stem-like properties in primary MMTV-PyMT mammary cancer cells. Their findings identify pathway crosstalk as a candidate mechanism of tumor-cell plasticity, while leaving its precise molecular steps and relevance across breast cancer subtypes to be tested.

Oleic Acid in Hepatic Lipid Injury Assays
2026-09-26
Use Oleic Acid to build controlled hepatocyte lipid models and test how lipid context shapes injury and rescue. This practical guide distinguishes a single-fatty-acid experiment from the oleic acid–palmitic acid model used in a recent hepatic ischemia-reperfusion study, with workflow choices and troubleshooting to improve interpretability.

Affordable GRO-seq for Nascent RNA Profiling in Wheat
2026-09-25
This protocol places rRNA depletion after nuclear RNA isolation and before nascent-RNA immunopurification, improving the sequencing efficiency of GRO-seq in allohexaploid bread wheat. The authors report a 20-fold increase in the proportion of valid data, offering a practical route to enhancer-transcription profiling in a complex plant genome.

SCP4 Dephosphorylates H3T3 to Protect Chromosomes
2026-09-25
The study identifies nuclear phosphatase SCP4 as a counter-regulator of mitotic histone H3 threonine-3 phosphorylation (H3T3), linking its activity to chromosomal passenger complex recruitment and accurate chromosome segregation. Cell-based and mouse-zygote findings indicate that disrupting SCP4 is associated with mitotic errors and aneuploidy, extending the known control of H3T3 beyond its kinase, Haspin.

N4-Acetylcytidine Assay Workflows
2026-09-24
Use N4-Acetylcytidine to distinguish free-nucleoside processing from modification of ac4C-containing RNA—a distinction highlighted by recent ASCH protein structures. This practical guide covers stock preparation, turnover assays, RNA controls, and troubleshooting without treating the free nucleoside as a substitute for modified RNA.

Benzyl-activated Streptavidin Magnetic Beads (SKU: K1301)
2026-09-23
These streptavidin magnetic beads provide a magnetically recoverable solid phase for capturing biotinylated proteins, peptides, antibodies, and nucleic acids from mixtures. Use them when the target is biotinylated and streptavidin binding is compatible with downstream analysis; avoid direct use in workflows sensitive to sodium azide or where strong-affinity capture makes gentle target release essential.
