Applied and environmental microbiology

Cerning J, Renard CM, Thibault JF, Bouillanne C, Landon M, Desmazeaud M, Topisirovic L.
PMID: 16349427
Appl Environ Microbiol. 1994 Nov;60(11):3914-9. doi: 10.1128/aem.60.11.3914-3919.1994.

Exopolysaccharide production by Lactobacillus casei CG11 was studied in basal minimum medium containing various carbon sources (galactose, glucose, lactose, sucrose, maltose, melibiose) at concentrations of 2, 5, 10, and 20 g/liter. L. casei CG11 produced exopolysaccharides in basal minimum...

RNA G-quadruplexes and their potential regulatory roles in translation.

Translation (Austin, Tex.)

Song J, Perreault JP, Topisirovic I, Richard S.
PMID: 28090421
Translation (Austin). 2016 Oct 04;4(2):e1244031. doi: 10.1080/21690731.2016.1244031. eCollection 2016.

DNA guanine (G)-rich 4-stranded helical nucleic acid structures called G-quadruplexes (G4), have been extensively studied during the last decades. However, emerging evidence reveals that 5'- and 3'-untranslated regions (5'- and 3'-UTRs) as well as open reading frames (ORFs) contain...

Translational reprogramming marks adaptation to asparagine restriction in cancer.

Nature cell biology

Pathria G, Lee JS, Hasnis E, Tandoc K, Scott DA, Verma S, Feng Y, Larue L, Sahu AD, Topisirovic I, Ruppin E, Ronai ZA.
PMID: 31740775
Nat Cell Biol. 2019 Dec;21(12):1590-1603. doi: 10.1038/s41556-019-0415-1. Epub 2019 Nov 18.

While amino acid restriction remains an attractive strategy for cancer therapy, metabolic adaptations limit its effectiveness. Here we demonstrate a role of translational reprogramming in the survival of asparagine-restricted cancer cells. Asparagine limitation in melanoma and pancreatic cancer cells...

Regulation of gene expression via translational buffering.

Biochimica et biophysica acta. Molecular cell research

Kusnadi EP, Timpone C, Topisirovic I, Larsson O, Furic L.
PMID: 34599983
Biochim Biophys Acta Mol Cell Res. 2022 Jan;1869(1):119140. doi: 10.1016/j.bbamcr.2021.119140. Epub 2021 Sep 30.

Translation of an mRNA represents a critical step during the expression of protein-coding genes. As mechanisms governing post-transcriptional regulation of gene expression are progressively unveiled, it is becoming apparent that transcriptional programs are not fully reflected in the proteome....

To survive, mammalian cells must adapt to environmental challenges. While the cellular response to mild stress has been widely studied, how cells respond to severe stress remains unclear. We show here that under severe hyperosmotic stress, cells enter a...

In response to disturbed mitochondrial gene expression and protein synthesis, an adaptive transcriptional response sharing a signature of the integrated stress response (ISR) is activated. We report an intricate interplay between three transcription factors regulating the mitochondrial stress response:...

Cell. 2011 Apr 29;145(3):333-4. doi: 10.1016/j.cell.2011.04.006.

The ribosome plays a universally conserved role in catalyzing protein synthesis. Kondrashov et al. (2011) now provide evidence that the loss of function of ribosomal protein L38 in mice leads to a selective reduction in the translation of Hox...

Co-translational mechanisms of quality control of newly synthesized polypeptides.

Translation (Austin, Tex.)

PMID: 26779401
Translation (Austin). 2014 Feb 13;2(1):e28109. doi: 10.4161/trla.28109. eCollection 2014.

During protein synthesis, nascent polypeptides emerge from ribosomes to fold into functional proteins. Misfolding of newly synthesized polypeptides (NSPs) at this stage leads to their aggregation. These misfolded NSPs must be expediently cleared to circumvent the deleterious effects of...
