2024
Invasion is a major biological phenomenon in the development and progression of cancer. This process is influenced by non-neoplastic cells and components of the tumor microenvironment. The purpose of this study is to describe an alternative method for analyzing tumor cell invasion in vitro using three-dimensional (3D) cultures.

Here, we describe a single cell micro-aspiration method for the separation of infected amoebae. In order to separate viral subpopulations in Vermamoeba vermiformis infected by Faustoviruses and unknown giant viruses, we developed the protocol detailed below and demonstrated its ability to separate two low-abundance novel giant viruses.

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity. There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

FAQs
Sequential changes allow a material interface to present different interactions over the course of assembly. Each introduced surface chemistry, layer, or molecular component can alter the interface’s behavior under defined conditions. This makes interfacial properties adjustable during design rather than treated as an unchanging characteristic, supporting materials tailored to particular biological environments.
The approach can support control over adhesion, permeability, biocompatibility, and drug-release behavior. These properties describe how a material interacts with surrounding biological systems, allows substances to pass through, remains compatible with tissues, or delivers a therapeutic component. Different medical applications can therefore emphasize different interface characteristics while using the same general design principle.
Defined conditions provide the framework for introducing alternating surface chemistries, layers, or molecular components in a structured sequence. Consistent control of the assembly process helps produce the intended interface rather than an uncontrolled arrangement. This organization is important because the resulting structure influences how the material behaves when used in a biological environment.
Changing the chemistry or composition presented at an interface can modify how that material interacts with its surroundings. Depending on the design, the resulting interface may support stronger or more appropriate adhesion, altered permeability, improved biocompatibility, or a different release behavior. These changes give researchers a way to match material performance with the needs of a specific medical application.
A basic workflow uses repeated assembly steps in which different surface chemistries, layers, or molecular components are introduced one after another. The sequence is performed under defined conditions to create a structured interface. Researchers can then use the resulting material, coating, membrane, or delivery system to obtain the intended interfacial behavior and performance.
The strategy can be applied to biomaterials, coatings, membranes, and drug-delivery systems. In each platform, interface control can address a different functional goal, such as influencing adhesion, regulating permeability, supporting biocompatibility, or tailoring release behavior. Its value lies in adapting the material’s interaction with a biological environment rather than relying on a single fixed interface.
