La recherche de la surexpression de la protéine et l'amplification du gène HER2 dans le cancer de l'estomac par immunohistochimie et Hybridation in Situ: expérience du CHU HASSAN II de Fès

The Pan African Medical Journal, 2012
La surexpression de l'Her2 a été détectée dans plusieurs cancers et a été particulièrement étudiée dans le cancer du sein. [1] Elle est décrite dans 10 à 30% des adénocarcinomes gastriques. Un statut HER2 positif est un facteur de mauvais pronostic et un

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Signal growth in a pure time-modulated transmission line and the loss effect

Royal Society Open Science
We present the first comprehensive study for signal growth in transmission lines (TL) with purely time-modulated characteristic impedance [Formula: see text] (infinite superluminality).

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Heat-Induced Fragmentation and Adapter-Assisted Whole Genome Amplification Using GenomePlex® Single-Cell Whole Genome Amplification Kit (WGA4)

, 2015
Whole genome amplification (WGA) is a widely used technique allowing multiplying picogram amounts of target DNA by several orders of magnitude. The technique described here is based on heat-induced random fragmentation yielding DNA strands mainly ranging

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
