Comprehensive profiling of lncRNAs and mRNAs enriched in small extracellular vesicles for early noninvasive detection of colorectal cancer: diagnostic panel assembly and extensive validation

Molecular Oncology, EarlyView.
Small extracellular vesicles are a promising source of diagnostic molecules. We conducted a comprehensive study, including transcriptome profiling and RT‐qPCR validation on large cohorts of samples. Diagnostic panels enabling sensitive detection of colorectal cancer and precancerous lesions were established. Some molecules were differentially expressed

Targeting of PTP4A3 overexpression sensitises HGSOC cells towards chemotherapeutic drugs

Molecular Oncology, EarlyView.
In HGSOC with normal KRAS expression, high PTP4A3 expression regulates autophagy activation. Conversely, in HGSOC with high KRAS expression, KRAS dictates autophagy control, and PTP4A3 is not required. When high PTP4A3 expression is inhibited, HGSOC cells are preferentially sensitised towards DNA‐damaging agents.

Pericytes change function depending on glioblastoma vicinity: emphasis on immune regulation

Molecular Oncology, EarlyView.
Pericytes alter their transcriptome depending on their proximity to the tumor core. In the tumor core, pericytes display a more active state with higher communication strength but with lower immune activation potential and a shift toward extracellular matrix production.

SensRORing cholesterol to drive protumoral myelopoiesis

Molecular Oncology, EarlyView.
Bleve et al. uncover a cholesterol‐driven immune evasion pathway, where RORγ‐dependent myelopoiesis shapes tumor immunosuppression. Targeting RORγ and PCSK9 emerges as a strategy to boost cancer immunotherapy. Protumoral myelopoiesis is a determinant of immunoevasion and tumor spread in many malignancies.

Interplay of Klebsiella pneumoniae fabZ and lpxC Mutations Leads to LpxC Inhibitor-Dependent Growth Resulting from Loss of Membrane Homeostasis

mSphere, 2018
Tight coordination of inner and outer membrane biosynthesis is very important in Gram-negative bacteria. Biosynthesis of the lipid A moiety of lipopolysaccharide, which comprises the outer leaflet of the outer membrane has garnered interest for Gram ...

Lipid Sorting: Lipids Do It on Their Own [PDF]

Current Biology, 2005
How are lipid molecules sorted between organelles in eukaryotic cells? A recent paper shows that the work needed to bend a membrane and form a vesicle is sufficient to sort lipid molecules.

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

FEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

Synthesis of resorcinolic lipids bearing structural similarities to cytosporone A

Química Nova, 2009
Inspired by the structure and biological activities of resorcinolic lipids and, particularly cytosporone A- a potent inhibitor of plantule germination and growth, we have performed the synthesis of the analogs 3-heptyl-3-hydroxy-5,7-dimethoxy-2 ...

Lipid science and lipid commerce [PDF]

Arkivoc, 2002
Lipid science is now an important and respected field of endeavour involving many individual sciences though this was not always true for organic chemists. The reasons for this change are discussed. Some current topics of interest are described including dietary recommendations, transgenic genetic modification of oilseeds, developments in analytical ...

Protein O‐glycosylation in the Bacteroidota phylum

FEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.
