Le jeu des identités ou la plasticité du lexème « intégration »

open access: yesLa Bretagne Linguistique, 1998
This article looks at the way in which individuals express their identity both in terms of abstract, even mythical, stability and, at the same time, in terms of the multiple variations that each individual allows himself thanks, no doubt, to these ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Forest Germans: a forgotten ethnic group in the contemporary landscape of the Polish Carpathians

open access: yesMiscellanea Geographica: Regional Studies on Development
In the 1340s, the Kingdom of Poland expanded eastwards, prompting large-scale settlement in the Wisłoka and Wisłok river basins, formerly a borderland between Poland and Ruthenia. This initiative integrated German and Polish settlers, who became known as

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

open access: yesMolecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

open access: yesMolecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

A Niche in a Conflict Area: The Development of the Baptist Church in the Areas of Petrinja, Glina, Sisak and Dvor

open access: yesMigracijske i etničke teme, 2007
One of the aspects of social changes during the transitional period in most post-socialist countries was the revival of religion. The revival of Churches that accompanied the national upsurge in some countries was associated with the growth of post ...

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Czech minority in Banat-Romania: A social geography survey [PDF]

open access: yesGeographica Pannonica, 2011
This paper describes the Czech minority living in SW part of Romania, namely in the Banat region. The community is concentrated in six villages, where they still keep their language and national habitudes since 1820, when the first families came.

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

open access: yesMolecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...
