3D bioprinting of hydrogels for retina cell culturing [PDF]

Bioprinting, 2018
Recapitulating native retina environment is crucial in isolation and culturing of retina photoreceptors (PRs). To date, maturation of PRs remains incomprehensible in vitro. Here we present a strategy of integrating the physical and chemical signals through 3D-bioprinting of hyaluronic acid (HA) hydrogels and co-differentiation of retinal progenitor ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

3D cell culture models: Drug pharmacokinetics, safety assessment, and regulatory consideration

Clinical and Translational Science, 2021
Nonclinical testing has served as a foundation for evaluating potential risks and effectiveness of investigational new drugs in humans. However, the current two‐dimensional (2D) in vitro cell culture systems cannot accurately depict and simulate the rich

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Identification of the plant mitochondrial OrfX protein: A mass spectrometry approach

FEBS Letters, EarlyView.
The mitochondrial genome of plants contains an open reading frame, orfx, which encodes a rare protein that has so far escaped mass spectrometric detection. The protein resembles the c‐subunit of bacterial twin‐arginine‐motif‐dependent protein translocases (TatC).

Kinetics of MM1.S Multiple Myeloma Cells in a 3D Polymer Particle Culture System with Bone Marrow Stromal Cells and Bortezomib

Pharmaceuticals
Background: Three-dimensional (3D) culture systems use polymer particles with a bone marrow stroma cell feeder layer to reproduce a biostructural hematopoiesis state more effectively than in conventional two-dimensional (2D) culture methods.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Electrical Impedance Determination of Cancer Cell Viability in a 3-Dimensional Cell Culture Microfluidic Chip

International Journal of Electrochemical Science, 2012
A technique of quantitative determination of cell viability in three-dimensional (3D) cell culture construct is proposed based on on-site electrical impedance measurement in a microfluidic chip.
