Isoastragaloside I
Based on 2 publication(s) in Google Scholar
Isoastragaloside I is a natural compound found in Astragalus membranaceus, with oral activity and multiple biological activities such as anti-inflammatory and antioxidant properties. Isoastragaloside I inhibits Akt, NF-κB, MAPKs and PI3K, enhances the activity of hepatic FXR, regulates the TGF-β/Smads signaling pathway, and upregulates antioxidant molecules downstream of Nrf2. Isoastragaloside I inhibits the expression of NO, TNF-α, iNOS, COX-2, IL-1β and VCAM-1, and reduces intracellular ROS levels. Isoastragaloside I attenuates blood-brain barrier disruption, restores intestinal barrier function, increases β-cell mass, improves glucose homeostasis, and elevates circulating adiponectin levels. Isoastragaloside I can be used for the study of neuroinflammation-related neurodegenerative diseases, cholestatic liver disease, and diabetes.

RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

ROS/oxidative-stress fluorescent staining
ROS/oxidative-stress fluorescent staining uses cell-permeant fluorogenic probes that become fluorescent after oxidation inside cells or tissues; commonly used examples include DCFH-DA/DCFDA for broad cellular oxidant detection, DHE for superoxide-related signal detection, MitoSOX for mitochondrial superoxide-related signal detection, and CellROX probes for oxidative-stress-associated fluorescence readouts. The assay detects probe oxidation rather than a single ROS species unless the probe and analysis method have been chemically validated for that species. DCFH-DA enters cells, is deacetylated by intracellular esterases to DCFH, and produces fluorescent DCF after oxidation, so the readout is used as an operational measure of total cellular oxidative stress rather than a species-specific ROS measurement. DHE and MitoSOX can report superoxide-related oxidation, but red fluorescence alone can include non-specific ethidium-like oxidation products; HPLC or optimized spectral approaches are

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

Research Protocol for Neurological Diseases
PINK1/Parkin-mediated mitophagy pathway is a mitochondrial quality-control signaling axis in which mitochondrial depolarization stabilizes PINK1 on damaged mitochondria, activates Parkin recruitment and E3 ubiquitin ligase activity, promotes ubiquitination of outer mitochondrial membrane proteins, recruits selective autophagy adaptors, and drives lysosomal degradation of damaged mitochondria. In neurological disease research, this pathway is experimentally important because neurons, especially dopaminergic neurons, are highly dependent on mitochondrial integrity, and defective mitochondrial turnover can lead to mitochondrial dysfunction, oxidative stress, impaired neuronal survival, α-synuclein accumulation, and neuroinflammatory damage-associated signals. The genetic disease link is strongest in Parkinson’s disease because mutations in PRKN/parkin cause autosomal recessive juvenile parkinsonism, mutations in PINK1 cause hereditary early-onset Parkinson’s disease, and Drosophila studie

Research Protocol for Metabolic Diseases
AMP-activated protein kinase, AMPK, is a conserved cellular energy sensor that responds to reduced cellular energy status and coordinates metabolism by increasing ATP-generating catabolic pathways while suppressing ATP-consuming anabolic processes. In metabolic disease research, the AMPK pathway is experimentally relevant because it regulates hepatic lipid synthesis, fatty acid oxidation, glucose production, skeletal-muscle glucose disposal, mTORC1-linked biosynthesis, autophagy, mitochondrial homeostasis, and whole-body energy balance. The central pathway logic is that energy stress, metformin, exercise-like stimulation, or direct AMPK activators increase AMPKα Thr172 phosphorylation and downstream substrate phosphorylation, including ACC and RAPTOR. Phosphorylation of ACC suppresses lipogenesis and supports fatty acid oxidation, whereas phosphorylation of RAPTOR suppresses mTORC1 signaling and links cellular energy status to growth and protein synthesis control. The pathway is linked

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
