The transcriptional repressor domain of Gli3 is intrinsically disordered. [PDF]
PLoS ONE, 2013 The transcription factor Gli3 is acting mainly as a transcriptional repressor in the Sonic hedgehog signal transduction pathway. Gli3 contains a repressor domain in its N-terminus from residue G106 to E236.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Identification of Chimeric Repressors that Confer Salt and Osmotic Stress Tolerance in Arabidopsis
Plants, 2013 We produced transgenic Arabidopsis plants that express chimeric genes for transcription factors converted to dominant repressors, using Chimeric REpressor gene-Silencing Technology (CRES-T), and evaluated the salt tolerance of each line.

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Interplay of protein and DNA structure revealed in simulations of the lac operon. [PDF]
PLoS ONE, 2013 The E. coli Lac repressor is the classic textbook example of a protein that attaches to widely spaced sites along a genome and forces the intervening DNA into a loop.

Revista Brasileira de Cancerologia, 2023 O presente trabalho demonstra que o efeito “repressor” da glicose sôbre TT no fígado não se apresenta se o animal fôr previamente tratado com 5-PU. Porém, o 5-FU não evita o efeito da glicose, se fôr administrado depois dêste glicidio.

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Allostery and applications of the lac repressor [PDF]
, 2014 The lac repressor has been extensively studied for nearly half a century; this long and complicated experimental history leaves many subtle connections unexplored.

Suicide Model of PER Repressor
, 2013 (A) In Drosophila, phosphorylation of the perSD motif is associated with strong repression activity. When this strong repressor turns off the transcription by binding to the transcriptional machinery, it triggers proteasomal degradation of PER protein ...

Molecular Oncology, EarlyView.Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).
