Combined Effects of Drugs: Synergism01:27

Combined Effects of Drugs: Synergism

6.4K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Gene-Environment Interactions01:20

Gene-Environment Interactions

1.5K
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Classical Conditioning in Daily Life

2.9K
Classical conditioning, a fundamental principle of associative learning, explains various phenomena observed in daily life, such as fear development, the placebo effect, taste aversion, and drug habituation. These applications demonstrate the profound impact of associative learning on human behavior and physiological responses.
John B. Watson and Rosalie Rayner famously demonstrated the development of fear through classical conditioning in their experiment with Little Albert. They paired the...

Real-World Application of Classical Conditioning

2.6K
Classical conditioning not only includes the initial pairing of stimuli but also extends to more complex forms, such as higher-order conditioning. Higher-order conditioning involves creating associations beyond the primary conditioned stimulus, resulting in a chain of conditioned responses.
Higher-order, or second-order, conditioning occurs when a neutral stimulus becomes associated with an already established conditioned stimulus through repeated pairings. For instance, if a dog has been...

Long-term Potentiation01:25

Long-term Potentiation

2.7K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Area of Science:

  • Computational biology
  • Pharmacology
  • Artificial intelligence

Background:

  • Drug combinations are vital for overcoming cancer resistance.
  • Current deep learning models for drug synergy lack dynamic cell-drug environment modeling.
  • This limitation hinders the prediction of environment-specific synergistic effects.

Purpose of the Study:

  • To develop a deep learning framework, Env-Syn, that dynamically models cell-drug interactions for improved synergy prediction.
  • To capture how the cellular environment modulates drug representations for environment-specific synergy.

Main Methods:

  • Env-Syn utilizes Environment-Conditioned Feature Modulation.
  • A Residual Feature-wise Linear Modulation (R-FiLM) module performs affine transformations on drug representations.
  • These transformations are conditioned on paired drugs and cellular environments.

    • Main Results:

    • Env-Syn consistently outperforms state-of-the-art methods in benchmark evaluations.
    • The model demonstrates exceptional generalization, with AUROC and AUPRC exceeding 0.81 in leave-drug-out settings for unseen drugs.
    • Env-Syn shows strong cross-dataset reliability and identified 8 literature-supported novel drug combinations out of 15 predictions.

    Conclusions:

    • Env-Syn is an effective computational tool for discovering drug synergy.
    • The framework accurately models drug-drug-cell interactions, improving prediction of synergistic effects.
    • Env-Syn shows promise for identifying novel, effective cancer drug combinations.
