THE COMMUTATIVITY OF PRIME NEAR RINGS

open access: yesInternational Journal of Research -GRANTHAALAYAH, 2018
Let N be a near-ring, and σ be an automorphisms of N. An additive mapping d from a near-ring N into itself is called a reverse σ-derivation on N if d (xy) = d(y) x + σ(y) d(x), holds for all x, y∈ N. In this paper, we shall investigate the commutativity of N by a reverse σ-derivation d satisfied some properties, when N is a prime ring.

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential

open access: yesMolecular Oncology, EarlyView.
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

Generalized Derivations of Prime Rings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
LetRbe an associative prime ring,Ua Lie ideal such thatu2∈Ufor allu∈U. An additive functionF:R→Ris called a generalized derivation if there exists a derivationd:R→Rsuch thatF(xy)=F(x)y+xd(y)holds for allx,y∈R. In this paper, we prove thatd=0orU⊆Z(R)if any one of the following conditions holds: (1)d(x)∘F(y)=0, (2)[d(x),F(y)=0], (3) eitherd(x)∘F(y)=x ...

Purification and characterization of a thermophilic NAD+‐dependent lactate dehydrogenase from Moorella thermoacetica

open access: yesFEBS Open Bio, EarlyView.
The thermophilic acetogenic model organism Moorella thermoacetica can utilize lactate as substrate. The formation of lactate by reduction of pyruvate is energetically favorable, but the reverse reaction, the oxidation of lactate to pyruvate with NAD+ as electron acceptor is challenging.

$\mathscr{T}$-Commuting Generalized Derivations on Ideals and Semi-Prime Ideal

open access: yesBoletim da Sociedade Paranaense de Matemática
This paper's primary goal is to look at a quotient ring $\mathscr{A}/\mathscr{T}$ structure, where $\mathscr{A}$ is an arbitrary ring and $\mathscr{T}$ is a semi-prime ideal of $\mathscr{A}$.

Prime Ideals in Enveloping Rings [PDF]

open access: yesTransactions of the American Mathematical Society, 1987
Let L L be a Lie algebra over the field K K of characteristic 0 0 and let U ( L ) U(L) denote its universal enveloping algebra. If R R is a K K -algebra and L L acts on R R as ...

HDAC4 regulates apoptosis in Acan‐CreERT2;HDAC4d/d mice with osteoarthritis by downregulating ATF4

open access: yesFEBS Open Bio, EarlyView.
Using the AcanCreERT2;HDAC4fl/fl genetic mouse model, we further investigated the role of histone deacetylase 4 (HDAC4) in chondrocyte apoptosis. We found that knocking down HDAC4 may be associated with chondrocyte apoptosis by upregulating the activating transcription factor 4 (ATF4)/CAAT/enhancer binding protein homologous (CHOP) signaling pathway ...

Pharmacological effects of osimertinib on a chicken chorioallantoic membrane xenograft model with the EGFR exon‐19‐deleted advanced NSCLC mutation

open access: yesFEBS Open Bio, EarlyView.
Osimertinib reduces angiogenesis and PDL1 expression in in ovo tumors, transforming them into ‘cold tumors’ with lower immune activity. Anatomopathological and transcriptomic analyses highlight its therapeutic impact on tumor biology. This study underscores osimertinib's potential to reshape the tumor microenvironment and provides insights into its ...
