Introduction:
Cerebral ischemia is considered to be a highly complex disease resulting from the complicated interplay of multiple pathways. Disappointedly, most of the previous studies were limited to a single gene or a single pathway. The extent to which all involved pathways are translated into fusing mechanisms of a combination therapy is of fundamental importance.
Aims:
We report an integrative strategy to reveal the additive mechanism that a combination (BJ) of compound baicalin (BA) and jasminoidin (JA) fights against cerebral ischemia based on variation of pathways and functional communities.
Results:
We identified six pathways of BJ group that shared diverse additive index from 0.09 to 1, which assembled broad cross talks from seven pathways of BA and 16 pathways of JA both at horizontal and vertical levels. Besides a total of 60 overlapping functions as a robust integration background among the three groups based on significantly differential subnetworks, additive mechanism with strong confidence by networks altered functions.
Conclusions:
These results provide strong evidence that the additive mechanism is more complex than previously appreciated, and an integrative analysis of pathways may suggest an important paradigm for revealing pharmacological mechanisms underlying drug combinations.
Insights
This study reveals how a combination therapy of baicalin (BA) and jasminoidin (JA) combats cerebral ischemia by integrating multiple pathways. The findings highlight the complexity of additive mechanisms in combination drug therapies.
Area of Science:
- Pharmacology
- Neuroscience
- Systems Biology
Background:
- Cerebral ischemia is a complex disease involving multiple interacting pathways.
- Previous research often focused on single genes or pathways, limiting understanding of combination therapies.
- Understanding integrated pathway mechanisms is crucial for effective combination treatments.
Purpose of the Study:
- To investigate the additive mechanism of a combination therapy (BJ) of baicalin (BA) and jasminoidin (JA) against cerebral ischemia.
- To analyze pathway variations and functional communities influenced by the BJ combination.
- To reveal the synergistic effects of BA and JA in treating cerebral ischemia.
Main Methods:
- Utilized an integrative strategy to analyze pathway variations and functional communities.
- Examined cross-talk between pathways at horizontal and vertical levels for individual compounds and the combination.
- Identified overlapping functions and differential subnetworks among BA, JA, and BJ groups.
Main Results:
- Identified six key pathways in the BJ group with additive indices ranging from 0.09 to 1.
- Observed extensive cross-talk from seven pathways of BA and 16 pathways of JA.
