Project description:Pancreatic cancer (PC) is a lethal malignancy of the digestive system with an extremely low survival rate. Schisandrin B (Sch B) has demonstrated novel pre-clinical antitumor activity in several animal tumor models. However, it remains unclear whether Sch B exerts antitumor effects in PC. The molecular mechanisms underlying the antitumor properties of Sch B were explored using RNA sequencing.
Project description:To explore how Schisandrin (SCH) regulates biological functions of fibroblast-like synovioctyes (FLSs) from rheumatoid arthritis (RA) patients, we evaluated the transcriptome of SCH-treated RA FLSs compared with untreated control using RNA sequencing analysis.
Project description:Based on the genome sequencing and gene annotation, we analyzed the alginate lyases and other genes related to alginate metabolism of strain Vibrio sp. C42, with the highest alginate-degrading activity. Combined with proteome measurement, we proposed its alginate metabolic pathways.
Project description:Introduction: This study investigates the active component Mannose-B from Codonopsis pilosula and its effect on human trophoblast cell function, particularly focusing on the regulation of Laminin Subunit Beta 1 (LAMB1) expression and its implications in subchorionic hematoma (SCH). Methods: Key genes involved in SCH pathology were identified through RNA sequencing and bioinformatics analysis. Network pharmacology was utilized to screen active components in Codonopsis pilosula and their critical targets. In vitro, HTR-8/Svneo cells were used to assess proliferation, migration, and invasion through CCK8, Transwell, and cell migration assays. A SCH rat model was established to evaluate changes in coagulation parameters, litter size, fetal viability, and fetal and placental weights. In vivo validation of Mannose-B's effects on LAMB1 expression and SCH pathology was performed using RT-qPCR and Western Blot. Results: Network pharmacology and molecular docking identified Mannose-B as an effective compound in Codonopsis pilosula, potentially beneficial for SCH treatment, with LAMB1 as a significant target. In vitro experiments showed that Mannose-B enhanced HTR-8/Svneo cell proliferation, migration, and invasion by reducing LAMB1 expression. In vivo experiments confirmed Mannose-B's inhibitory effect on placental LAMB1 expression and its potential in ameliorating SCH pathology. Conclusion: Mannose-B from Codonopsis pilosula inhibits LAMB1 expression, promoting human placental trophoblast cell proliferation, migration, and invasion, thereby mitigating the progression of SCH pathology.
