Based on 2 publication(s) in Google Scholar
Astragaloside II is an orally active Cycloartane-type triterpene glycoside. Astragaloside II can be extracted from Astragalus membranaceus. Astragaloside II inhibits Autophagy, decreases pro-inflammatory cytokines (IL-6, IL-1β), HIF-α, p-p65, p-IκB and increases SOD. Astragaloside II regulates immunity and reduces inflammatory responses. Astragaloside II can be used in the research of diseases such as liver cancer, osteoporosis, immunosuppressive diseases, and ulcerative colitis.

LPS-Induced Endotoxemia/Systemic Inflammation
Lipopolysaccharide (LPS)-induced endotoxemia is a widely used in vivo model of acute systemic inflammation in which LPS, a Gram-negative bacterial endotoxin, activates innate immune signaling primarily through TLR4, leading to rapid and transient induction of pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1β in circulation and tissues. This cytokine surge is commonly used as a measurable readout of systemic inflammatory activation and immune dysregulation, and is typically assessed within hours after intraperitoneal LPS administration in mouse models of endotoxemia. The model captures key features of systemic inflammatory response syndrome, including cytokine release, immune cell activation, and downstream tissue responses, and has been used to evaluate anti-inflammatory interventions such as cytokine modulation, lipid mediators, and immune cell-targeting therapies.

DSS-Induced Colitis
Dextran sulfate sodium (DSS)-induced colitis is generated by administering DSS in mouse drinking water, producing epithelial injury, barrier disruption, weight loss, diarrhea, fecal blood, colon shortening, histologic mucosal damage, and inflammatory mediator changes; the model is mainly used to study acute or chronic intestinal inflammation resembling selected features of ulcerative colitis. DSS injury is interpreted through clinical and tissue readouts rather than a single molecular endpoint: daily body weight, stool consistency, and bleeding are combined into a disease activity index, while colon length, histology, cytokines, myeloperoxidase activity, intestinal permeability, and tight-junction markers provide complementary measures of inflammation and barrier damage.
-
TNBS-Induced Colitis
TNBS-induced colitis is produced by intrarectal delivery of 2,4,6-trinitrobenzene sulfonic acid in ethanol, where ethanol disrupts the mucosal barrier and TNBS haptenates colonic proteins, generating immune-mediated colonic inflammation with weight loss, diarrhea, ulceration, transmural injury, inflammatory-cell infiltration, and cytokine responses. The model is used as an experimental intestinal inflammation model with Crohn’s disease–like features, especially when Th1-type responses, IL-12–dependent inflammation, chronic relapsing inflammation, or fibrosis-related endpoints are studied.

Autophagy
Autophagy is a process in which eukaryotic cells use lysosomes to degrade their own cytoplasmic proteins and damaged organelles under the regulation of autophagy related gene (Atg). Microtubule-associated proteins light chain 3 (LC3) is recognized as autophagy marker, which transfers from cytoplasmic LC3 (LC3-I) to membrane type (LC3-II). LC3-II/I ratio could be detected by Western Blot and fluorescence microscopy.

Lysosome and acidic-vesicle live-cell staining
Lysosome and acidic-vesicle live-cell staining detects acidic intracellular compartments by using membrane-permeant acidotropic probes that accumulate in low-pH vesicles, including lysosomes, late endosomes, autolysosomes, and acidic phagosomes. LysoTracker staining is commonly used as an intensity-based readout of acidic lysosomal compartment abundance or enlargement, while acridine orange produces green fluorescence in less concentrated compartments and red fluorescence after concentration-dependent accumulation in acidic vesicular organelles. Loss or reduction of acridine-orange red signal can be used as a readout of lysosomal membrane permeabilization or reduced acidic-vesicle integrity. This protocol is designed for live cultured cells and can be adapted for fluorescence microscopy, high-content imaging, plate-reader readout, or flow cytometry when the selected literature supports the readout. Because these dyes report acidotropic accumulation rather than lysosome identity alone,

Research Protocol for Inflammation-related Diseases
The NLRP3 inflammasome is a cytosolic innate immune signaling platform that integrates priming signals and danger-signal activation to promote caspase-1 activation, maturation of IL-1β and IL-18, and gasdermin D-mediated pyroptotic cell death. The core experimental logic is to determine whether inflammatory disease phenotypes are driven by increased NLRP3 expression, ASC-containing inflammasome assembly, caspase-1 cleavage, GSDMD cleavage, and extracellular release of IL-1β/IL-18 rather than by nonspecific cell injury alone. The pathway is strongly linked to inflammation-related disease phenotypes because monosodium urate crystals activate NALP3/NLRP3 inflammasome signaling in gout-like crystal inflammation, cholesterol crystals activate NLRP3 inflammasomes in atherogenesis models, and DSS-induced intestinal inflammation has been reported to involve NLRP3 inflammasome activity. However, experimental colitis studies also show context-dependent protective effects of NLRP3 inflammasome co

Liver Cancer Modeling
Liver cancer can be classified into primary liver cancer and secondary liver cancer. Secondary liver cancer is the metastatic liver cancer. Primary liver cancer includes hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and fibrolamellar HCC, of which HCC is the most common form, accounting for approximately 90% of primary liver cancers[1]. HCC mouse models include chemical agent-induced models, transplanted tumor models, and genetic engineered models.

Macroautophagy Solutions
Macroautophagy is a conserved lysosome-dependent degradation pathway in which cytoplasmic material is sequestered into double-membrane autophagosomes and delivered to lysosomes for degradation and recycling. The pathway supports cellular homeostasis during nutrient limitation, organelle stress, protein-aggregate accumulation, infection, differentiation, and tissue remodeling by coupling cargo sequestration, autophagosome maturation, lysosomal fusion, and degradation of cargo-derived macromolecules. The core molecular sequence includes initiation by nutrient- and stress-regulated autophagy machinery, autophagosome nucleation, LC3/ATG8-family conjugation to autophagosomal membranes, cargo selection through receptors such as SQSTM1/p62, autophagosome-lysosome fusion, and lysosomal degradation. LC3 was identified as a mammalian homolog of yeast Atg8 that localizes to autophagosomal membranes after processing, and p62/SQSTM1 was shown to connect ubiquitinated cargo with autophagic degradati

Pyroptosis Solutions
Pyroptosis is a lytic inflammatory cell-death pathway executed by gasdermin pores, most classically through inflammasome-mediated activation of caspase-1, cleavage of gasdermin D, membrane pore formation, LDH release, and secretion of IL-1β and IL-18. The canonical pathway is commonly modeled by priming cells with an inflammatory signal such as LPS to induce pro-IL-1β and inflammasome components, followed by an activation signal such as ATP or nigericin to activate NLRP3, ASC speck formation, caspase-1 cleavage, GSDMD cleavage, cytokine release, and pyroptotic membrane rupture. The non-canonical pathway is triggered when cytosolic LPS activates mouse caspase-11 or human caspase-4/5, leading to GSDMD cleavage and pyroptosis, and this can secondarily activate NLRP3-dependent IL-1β release. Pyroptosis is linked to inflammatory injury, infection, cancer, liver disease, ocular disease, placental inflammation, and other disease phenotypes, but unresolved questions include which gasdermin fam
