Incorporation of tritiated cytidine into ribonucleic acid by isolated pea nuclei [PDF]

open access: yes, 1962
A new method for the isolation of the nuclei from plant tissue has been devised. This method consists in passing the plant tissue through a set of spring-loaded, counter-rotating rollers and collecting the liberated nuclei in sucrose solution containing ...

SLPI/FBW7/c‐Myc Axis Reduces Gemcitabine Sensitivity in PDAC by Enhancing Glycolysis and Impairing NK Cell Immunity

open access: yesCancer Science, EarlyView.
SLPI reduces the sensitivity of PDAC to gemcitabine by competing with FBW7 for binding to c‐Myc, thereby disrupting FBW7‐dependent ubiquitination and proteasomal degradation of c‐Myc, leading to increased c‐Myc stability and expression. SLPI knockdown could significantly increase gemcitabine sensitivity to gemcitabine‐induced direct cytotoxicity and NK

Plant organelle C‐to‐U RNA editing factors can operate successfully in yeast (Saccharomyces cerevisiae) as an easily amenable eukaryotic system for their functional analysis

open access: yesThe FEBS Journal, EarlyView.
Plant‐type pentatricopeptide repeat proteins capable of C‐to‐U RNA editing perform faithfully when expressed in a new heterologous system, the yeast Saccharomyces cerevisiae. They were tested with constitutive and inducible expression and with a set of different solubility tags. PPR56, PPR65, and PPR78 from P.

Harnessing S. cerevisiae to advance the engineering of pentatricopeptide repeat proteins

open access: yesThe FEBS Journal, EarlyView.
Heterologous expression systems have been instrumental in furthering our understanding of plant RNA editing proteins. In this commentary, we discuss how the establishment of yeast as a model for studying plant RNA editing by Ramanathan et al. could advance the engineering of pentatricopeptide repeat proteins, and how in return pentatricopeptide repeat ...

Construction of Mycobacterium tuberculosis cdd knockout and evaluation of invasion and growth in macrophages

open access: yesMemorias do Instituto Oswaldo Cruz
Cytidine deaminase (MtCDA), encoded by cdd gene (Rv3315c), is the only enzyme identified in nucleotide biosynthesis pathway of Mycobacterium tuberculosis that is able to recycle cytidine and deoxycytidine. An M.

Comparative evaluation of noncanonical amino acids as site‐specific NMR probes for the complex of E. coli SSB with single‐stranded DNA without isotope labelling

open access: yesThe FEBS Journal, EarlyView.
Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.

Gene Editing for Haemophilia—The Next Frontier

open access: yesHaemophilia, EarlyView.
ABSTRACT The recently approved haemophilia A and B gene therapies via adeno‐associated virus (AAV) showed a promising therapeutic response after a single injection, but there are still limitations, including the potential loss of transgene expression and restriction in adults.

Cytosolic delivery of bacterial metabolites by riboflavin transporters promotes MR1 antigen presentation and MAIT cell recognition

open access: yesImmunology &Cell Biology, EarlyView.
VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.
