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

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
[[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]
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 ...

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
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 ...
