Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

A Simple Three-Dimensional Compartmentalized Co-Culture Model for Basal Forebrain and Hippocampal Neurons

open access: yesBiology
The basal forebrain (BF)-hippocampus (HPC) circuit is indispensable for learning and memory, and in vitro models are essential for dissecting its age-related decline.

From crypts to enteroids: establishment and characterization of avian intestinal organoids

open access: yesPoultry Science, 2022
: Intestinal organoids (IO), known as “mini-guts”, derived from intestinal crypts, are self-organizing three-dimensional (3D) multicellular ex vivo models that recapitulate intestine epithelial structure and function and have been widely used for ...

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome

open access: yesFEBS Letters, EarlyView.
In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Two-dimensional and three-dimensional cell culture models in vitro: pros and cons

open access: yesБюллетень сибирской медицины, 2018
Discovery and development of new chemical compounds with putative anti-cancer properties requires reliable predictive preclinical models for in vitro screening of efficacy.

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

open access: yesMolecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

QUANTITATIVE REPRESENTATION OF THREE-DIMENSIONAL CELL CULTURE MODELS [PDF]

open access: yes2007 4th IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2007
Three-dimensional mammary cell culture models offer new opportunities for the development of computational techniques for segmentation, localization, and multicellular organization. Under normal conditions, these assays form a symmetrical, hollow structure, which is necessary for their functional operation.
