Current progress in the derivation and therapeutic application of neural stem cells

open access: yesCell Death and Disease, 2017
Neural stem cells (NSCs) have a unique role in neural regeneration. Cell therapy based on NSC transplantation is a promising tool for the treatment of nervous system diseases.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

LEXICALIZATION IN MORPHOLOGY: A CASE STUDY OF THE ANTICAUSATIVE PREFIX IN TAQBAYLIT BERBER [PDF]

open access: yesStudii de gramatică contrastivă
What makes lexicalization an intriguing topic in morphology? It is not so much the semantic mismatch between a base and its ‘derived’ form, but the question of how lexicalization is underlyingly represented.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Generalized Derivations With Left Annihilator Conditions in Prime and Semiprime Rings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2017
Let R be a prime ring with its Utumi ring of quotients U, C = Z(U) be the extended centroid of R, H and G two generalized derivations of R, L a noncentral Lie ideal of R, I a nonzero ideal of R.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Этимологические заметки о русском семинарском жаргоне: ВЗЪЕФАНТУЛИТЬ, СМОРОЗИТЬ, АКСИОС(Ы) (= Some Etymological Notes on the Russian Seminarian Slang: VZʺEFANTULITʹ, SMOROZITʹ, AKSIOS(Y)) [PDF]

open access: yesSlovene, 2013
Три отдельные заметки объединены тем, что рассмотренные в них слова происходят из русского семинарского жаргона и являются грецизмами, причём в двух первых случаях неочевидными, каламбурными.

Hypercentral Derivations

open access: yesJournal of Algebra, 1994
Define generalized commutators for a ring \(R\) by \([x,y]_ 1 = xy - yx\) and for \(k > 1\) set \([x,y]_ k = [[x,y]_{k - 1},y]\), where \(x,y \in R\). The author proves that if \(R\) has no nonzero nil ideal and has a derivation \(D\) satisfying \([D(x^ n),x^ n]_ k = 0\) for \(k \geq 1\), all \(x\in R\), and \(n = n(x) \geq 1\), then the Utumi quotient

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
