On Automorphisms of Prime Rings with Involution

open access: yesDemonstratio Mathematica, 1997
Let \(R\) be a unital ring with involution. For every pair, \(x\) and \(y\) of elements of \(R\), we write \([x,y]=xy-yx\). We denote by \(Z(R)\) the center of \(R\), i.e., the set of elements \(x\in R\) such that \([x,x^*]=0\). Let \(f\) be a self-mapping of \(R\). We say that \(f\) is centralizing if \([f(x),x]\in Z(R)\), for every \(x\in R\). On the

Fully *-prime rings with involution

open access: yes, 2018
Some known results on fully prime rings and almost fully prime rings are extended to the category of rings with involution. In particular, various properties of fully *-prime involution rings are presented, a classification of fully *-prime involution

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

On some equations in prime rings

open access: yesMonatshefte für Mathematik, 2007
The bulk of this paper is its first theorem, which uses the notions of functional identity and \(d\)-freeness. To state this result let \(p(x_1,x_2,x_3)\) be the linearization of \(x^3\). The theorem is: If \(L\) is a 6-free Lie subring of a ring \(R\) with \(p(L^3)\subseteq L\), and if \(T\colon L\to R\) is additive and satisfies (*) \(T(x^3)=T(x)x^2 ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Prime Ideals and Homoderivations on Rings

open access: yesCumhuriyet Science Journal
In this paper, we aim to establish a new approach that involves characterizing the commutativity of a quotient ring L/P with homoderivations of L satisfying some algebraic identities involving the prime ideal P.

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

open access: yesMolecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

REMARKS ON GENERALIZED DERIVATIONS IN ∗−PRIME RINGS [PDF]

open access: yesJournal of Algebraic Systems
Let (R, ∗) be a ∗−prime ring with characteristic different from two, and L ̸= 0be a square closed ∗−Lie ideal of R. An additive mapping F : R −→ R is calleda generalized derivation on R if there exists a derivation d : R −→ R such thatF(xy) = F(x)y + xd ...

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.
