COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

On z-Ideals and z ◦ -Ideals of Power Series Rings

open access: yesJournal of Mathematical Extension, 2013
Let R be a commutative ring with identity and R[[x]] be the ring of formal power series with coefficients in R. In this article we consider sufficient conditions in order that P[[x]] is a minimal prime ideal of R[[x]] for every minimal prime ideal P ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Derivations on One-Sided Ideals of Prime Rings

open access: yes, 2015
[[abstract]]Let R be a prime ring, ρ a nonzero right ideal of R, d a derivation of R and n a fixed positive integer.(I) If d(u)u^n=0 for all u belong to ρ, then d(ρ)ρ=0.(II) If {u^n}d(u)=0 for all u belong to ρ, then d=0 unless R isomorphic to M_2(F ...

On the algebraic classification of K-local spectra [PDF]

open access: yes, 2008
In 1996, Jens Franke proved the equivalence of certain triangulated categories possessing an Adams spectral sequence. One particular application of this theorem is that the K(p)-local stable homotopy category at an odd prime can be described as the ...

On V-rings and prime rings

open access: yesJournal of Algebra, 1980
In this note, we find similar characteristic properties in terms of certain intersections of maximal left ideals for the following classes of rings: (1) Left V-rings; (2) Left f-V-rings; (3) Left p-V-rings. The well-known characterisation of v-rings due to Villamayor is weakened.

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

open access: yesMolecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...
