Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

7.4K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

12.3K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

The Anchoring-and-Adjustment Heuristic

7.3K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

6.9K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

ER Retrieval Pathway01:45

ER Retrieval Pathway

3.9K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Area of Science:

  • Computational pharmacology
  • Bioinformatics
  • Artificial Intelligence in Medicine

Background:

  • Traditional Chinese Medicine (TCM) is a long-standing practice with global recognition.
  • Current TCM herb recommenders rely solely on TCM theory, limiting integration with modern medicine.
  • A molecular-level understanding necessitates bridging TCM's empirical knowledge with modern pharmacological evidence.

Purpose of the Study:

  • To develop an explainable herb recommendation system for Traditional Chinese Medicine.
  • To integrate TCM principles with modern pharmacology for evidence-based recommendations.
  • To explore the molecular action mechanisms of herbs from both TCM and modern medicine perspectives.

Main Methods:

  • Proposed a Meta-path guided Graph Attention Network (MGAT) model.
  • Constructed an extended knowledge graph incorporating TCM and modern pharmacology.
  • Implemented a meta-path guided information propagation scheme with an attention mechanism for salient path selection.

Main Results:

  • The MGAT model achieved comparable performance to state-of-the-art herb recommendation systems.
  • Demonstrated strong explainability in herb recommendations.
  • Successfully integrated TCM knowledge with modern pharmacological data.

Conclusions:

  • The proposed MGAT model offers a robust framework for evidence-based TCM herb recommendations.
  • Integrating TCM and modern medicine through knowledge graphs enhances therapeutic potential.
  • The model provides fine-grained explanations, advancing TCM from an experience-based to an evidence-based system.
