Hedgehog Signaling Pathway

Hedgehog Signaling Pathway

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...

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Background:

Graph-theoretical (GT) representations offer a versatile framework for describing nanomaterial structures, analogous to chemical formulas.
Current methods for constructing GT models of complex particles and linking graph features to material properties are underdeveloped.

Purpose of the Study:

To develop methods for constructing GT models of complex particles, using hedgehog particles (HPs) as a model system.
To establish links between graph features and material properties for engineered nanomaterials.

Main Methods:

Synthesized HPs with systematically varied structural patterns (cores, spikes, materials).
Developed a process for building GT models, assigning subgraphs to structural elements identified via electron microscopy.
Analyzed complexity metrics of HPs based on dimensionality, hierarchy, and component variety.

Main Results:

Successfully constructed unique GT 'formulas' for HPs with diverse solid/hollow cores and spikes.
Identified key structural pattern aspects contributing to complexity: dimensionality, hierarchy, and component variety.
Observed enhanced dispersibility and strong Mie scattering in studied HPs, correlating with GT descriptions.

Conclusions:

GT models provide a robust method for describing complex hierarchical nanostructures.
The developed approach links structural complexity to material properties like dispersibility and scattering.
GT descriptions can guide the engineering of hierarchical particles for specific functionalities.
