Emerging roles of telomeric chromatin alterations in cancer [PDF]

open access: yes, 2019
Telomeres, the nucleoprotein structures that cap the ends of eukaryotic chromosomes, play important and multiple roles in tumorigenesis. Functional telomeres need the establishment of a protective chromatin structure based on the interplay between the ...

Structural basis of JAZ repression of MYC transcription factors in jasmonate signalling [PDF]

open access: yesNature, 2015
The plant hormone jasmonate plays crucial roles in regulating plant responses to herbivorous insects and microbial pathogens and is an important regulator of plant growth and development. Key mediators of jasmonate signalling include MYC transcription factors, which are repressed by jasmonate ZIM-domain (JAZ) transcriptional repressors in the resting ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

The limits of transnational solidarity : the Congress of South African Trade Unions and the Swaziland and Zimbabwean crises [PDF]

open access: yes, 2013
The Congress of South African Trade Unions (COSATU), the main union federation in South Africa, was instrumental in ending apartheid. This paper evaluates COSATU's post-apartheid role in working for democracy elsewhere in Southern Africa through ...

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 ...

About one more Organ of the Stalinist Period – Troikas and Petiorkas

open access: yesGenocidas ir Rezistencija, 2002
Informal formations of party and chekist organs – troykas, chetvyortkas, petyorkas – were formed on the instructions of the Lithuanian Bureau of the Central Committee of the Communist Party of Lithuania (LKP(b)); they began their more active operations ...

Repression and activation by multiprotein complexes that alter chromatin structure. [PDF]

open access: yesGenes & Development, 1996
Recent studies have provided strong evidence that macromolecular complexes are used in the cell to remodel chromatin structure during activation and to create an inaccessible structure during repression, Although there is not yet any rigorous demonstration that modification of chromatin structure plays a direct, causal role in either activation or ...

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 ...
