Fold changes were computed relative to untreated controls to generate normalized expression data for each target gene.","Hybridization - Real-time PCR amplification was carried out using SYBR Green Master Mix on a StepOnePlus™ Real-Time PCR System (Applied Biosystems). Relative mRNA expression levels were calculated using the 2^-ΔΔCt method, with β-actin as the internal control.","Sample Collection - Oral squamous carcinoma cell lines (HEP-2 and HN-9) were cultured under standard conditions (37 °C, 5% CO₂) in DMEM supplemented with 10% FBS and antibiotics. Cells were seeded in 6-well plates and treated according to the experimental design.","Labeling - cDNA synthesis was performed using a high-capacity cDNA reverse transcription kit (Applied Biosystems) following the manufacturer’s protocol.","Sample Treatment - Cells were treated with free Captopril or Captopril-Montmorillonite (CP-MMT) nanoparticles for 48 hours. Untreated cells served as controls.","Nucleic Acid Extraction - Total RNA was extracted from treated and control cells using TRIzol reagent according to the manufacturer’s instructions.
