Somatic cell reprogramming for Parkinson's disease treatment

open access: yesIbrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

Ribosomal RNA operon copy number: A trait‐informed framework to close the microbial cultivation gap

open access: yesiMetaOmics, EarlyView.
The vast majority of microbes remain uncultured, constraining functional validation and limiting microbiome‐based applications. We show that ribosomal RNA operon (rrn) copy number—a stable, phylogenetically conserved genomic trait—is strongly correlated with cultivation outcomes across ecosystems.

Structural Basis of the Light‐Switchable Interaction between an Azobenzene Side Chain in a Biosynthetic Protein and α‐Cyclodextrin

open access: yesChemistryOpen, EarlyView.
X‐ray crystallographic analysis of super‐folder green fluorescent protein (sfGFP), a common reporter protein, displaying p‐(phenylazo)‐L‐phenylalanine (Pap) at amino acid position 39 on its surface in complex with α‐cyclodextrin (α‐CD) reveals an unexpected conformation of the photoswitchable side chain and illustrates its light‐dependent ...

Preservation of bovine preantral follicle viability and ultra-structure after cooling and freezing of ovarian tissue [PDF]

open access: yes, 2008
Bovine preantral follicles within ovarian fragments were exposed and cryopreserved in absence or presence of 1.5 M glycerol (GLY), ethylene glycol (EG), propanediol (PROH) or dimethyl sulfoxide (DMSO), undergoing a previous cooling at 20 °C for 1 h ...

Structural Analysis and Inhibitor Modeling of Bacterioferritin From Brucella abortus

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Iron homeostasis in various pathogenic bacteria is regulated by bacterioferritins (Bfr) which function to store Fe3+ and release Fe2+ as needed for metabolic processes. The Bfr structure consists of 18 kDa subunits in which dimer pairs bind a heme molecule and are assembled into a highly symmetrical 24‐meric spherical structure with an ...

Structure of 3,4-Dihydroxy-2-butanone 4-Phosphate Synthase from Methanococcus jannaschii in Complex with Divalent Metal Ions and the Substrate Ribulose 5-Phosphate: implications for the catalytic mechanism [PDF]

open access: yes, 2003
Skeletal rearrangements of carbohydrates are crucial for many biosynthetic pathways. In riboflavin biosynthesis ribulose 5-phosphate is converted into 3,4-dihydroxy-2-butanone 4-phosphate while its C4 atom is released as formate in a sequence of metal ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.
