Scene 1: Rice Pistil Collection and Processing
Prompt: Scientific illustration, close-up of immature rice flowers (Oryza sativa), highlighting the pistils carefully dissected under a stereomicroscope using fine tweezers. The pistils are immediately flash-frozen in liquid nitrogen, surrounded by dramatic swirling cold vapors. Style: Clean, detailed, educational, with labels.

Scene 2: Tissue Grinding and Protein Lysis
Prompt: Cross-sectional schematic diagram showing frozen rice pistil tissue being ground into a fine green powder with liquid nitrogen in a pre-chilled mortar. The next panel shows the powder being transferred to a microcentrifuge tube placed on ice, containing cold lysis buffer. Style: Schematic, cross-sectional view, blue and white tones to emphasize the low-temperature environment.

Scene 3: Immunoprecipitation Core Process
Prompt: Immunoprecipitation (Co-IP) process infographic. 1) A tube containing multiple proteins, one labeled "MEL2" (red). 2) Anti-MEL2 antibody (Y-shaped) binds to MEL2. 3) Magnetic beads (gray spheres) coated with Protein A/G capture the antibody-MEL2 complex. 4) A magnet pulls the magnetic beads, leaving other proteins in solution. 5) Elution buffer releases MEL2 and its interacting proteins (various colored shapes attached to MEL2). Style: Flat vector design, clear sequential steps.

Scene 4: SDS-PAGE and Mass Spectrometry Identification
Prompt: A Coomassie blue-stained SDS-PAGE gel lane showing multiple protein bands. An arrow points from the entire lane to a mass spectrometer. An inset shows a conceptual mass spectrum peak plot and a list of identified protein names (e.g., "Candidate Interacting Protein 1", "Candidate Interacting Protein 2"). Style: Realistic laboratory photograph combined with digital data overlay.

A schematic diagram illustrating the experimental process, including the establishment of a hypoxia model in *Caenorhabditis elegans* induced by sodium sulfite to simulate plateau hypoxic injury. The study explores the integrated mechanism of pyrroloquinoline quinone (PQQ) against hypoxia-induced injury, with the core concept being that PQQ blocks the cell damage cascade triggered by hypoxia through multiple pathways, ultimately achieving cell protection and survival enhancement. Initial Damage Effects of Hypoxia: When cells are in a state of hypoxia, two key damage pathways are triggered: Mitochondrial Dysfunction and Electron Transport Chain (ETC) Leakage: Hypoxia disrupts the mitochondrial structure, leading to abnormal electron transport chains, which in turn triggers a burst of reactive oxygen species (ROS) / oxidative stress. Calcium Homeostasis Imbalance: Hypoxia causes abnormal opening of calcium channels on the cell membrane, resulting in a sharp increase in intracellular Ca²⁺ concentration, further exacerbating cellular dysfunction. Direct Antioxidant Effect of PQQ: PQQ blocks the source of hypoxic damage by directly scavenging ROS / exhibiting antioxidant activity: PQQ can directly react with ROS such as superoxide anions (O₂⁻), converting them into harmless H₂O₂ (while PQQ itself undergoes redox cycling), thereby inhibiting the cascade amplification of "ROS bursts." Regulation of Signaling Pathways by PQQ: Inhibition of p38 MAPK Overactivation: The ROS burst caused by hypoxia overactivates the p38 MAPK pathway: ROS activates the upstream kinase sek-1 (MAP2K), which in turn phosphorylates and activates p38 MAPK (pmk-1); Overactivation of p38 MAPK induces cell dysfunction, apoptosis signals, and even individual death. PQQ directly inhibits the overactivation of p38 MAPK by transcriptional reprogramming (such as regulating calcium signal-related genes), blocking this damage pathway. Final Protective Effect of PQQ: Through the above dual mechanisms (direct antioxidant + inhibition of p38 pathway), PQQ achieves: Cell Protection: Maintaining the normal structure and function of cells (including mitochondria); Physiological State Maintenance: Restoring intracellular environmental balance such as calcium homeostasis; Survival Enhancement: Blocking apoptosis signals and avoiding cell/tissue death. Core Logic: Hypoxia triggers cell death through a cascade reaction of "mitochondrial damage → ROS burst → p38 pathway overactivation"; PQQ intervenes simultaneously from two levels, the "source (scavenging ROS)" and the "signaling pathway (inhibiting p38)," ultimately reversing the damaging effects of hypoxia and achieving cell protection and enhanced survival.
