KPLH1130
Based on 2 publication(s) in Google Scholar
KPLH1130 is a pyruvate dehydrogenase kinase (PDK) inhibitor. KPLH1130 potently inhibits M1 macrophage polarization by reducing the expression of pro-inflammatory cytokines, decreasing the levels of M1 phenotype markers (HIF-1α, iNOS) and nitric oxide (NO) production. KPLH1130 prevents the reduction of mitochondrial oxygen consumption rate (OCR) induced by inflammatory stimuli (LPS ((HY-D1056) + IFN-γ) in various macrophage types. KPLH1130 improves glucose tolerance in HFD-fed mice. KPLH1130 can be used for the study of obesity-associated metabolic disorders and other inflammatory conditions.

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.

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.

Primary monocyte-to-macrophage differentiation
Primary human monocytes can be differentiated ex vivo into monocyte-derived macrophages by culturing purified blood monocytes for approximately 5-7 days in macrophage-supporting cytokine conditions; M-CSF commonly yields CD14^high/CD163^high macrophages, while GM-CSF yields a phenotypically distinct macrophage population, so the cytokine condition should be chosen according to the downstream model. The readout of successful differentiation is a combined change in morphology, adherence, surface phenotype, and function: differentiated macrophages become adherent, enlarge, acquire macrophage-associated markers such as CD14, CD68, CD163, CD206, or HLA-DR depending on culture condition, and show increased phagocytic capacity compared with starting monocytes.

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 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
