New therapeutic strategies to treat human cancers expressing mutant p53 proteins

G Blandino, S Di Agostino - Journal of Experimental & Clinical Cancer …, 2018 - Springer
The tumor suppressor p53 plays a critical role to preserve DNA fidelity from diverse insults
through the regulation of cell-cycle checkpoints, DNA repair, senescence and apoptosis. The …

[HTML][HTML] New molecular mechanisms and clinical impact of circRNAs in human cancer

G Fontemaggi, C Turco, G Esposito, S Di Agostino - Cancers, 2021 - mdpi.com
Simple Summary Circular RNAs (circRNAs) belong to a new class of non-coding RNAs
implicated in cellular physiological functions but also in the evolution of various human …

Oncogenic intra-p53 family member interactions in human cancers

M Ferraiuolo, S Di Agostino, G Blandino… - Frontiers in …, 2016 - frontiersin.org
The p53 gene family members p53, p73, and p63 display several isoforms derived from the
presence of internal promoters and alternative splicing events. They are structural homologs …

Gain of function of mutant p53: the mutant p53/NF-Y protein complex reveals an aberrant transcriptional mechanism of cell cycle regulation

S Di Agostino, S Strano, V Emiliozzi, V Zerbini… - Cancer cell, 2006 - cell.com
This article investigates the mechanistic aspects of mutant p53 "gain of function" in
response to DNA damage. We show that mutant forms of p53 protein interact with NF-Y. The …

PML, YAP, and p73 are components of a proapoptotic autoregulatory feedback loop

E Lapi, S Di Agostino, S Donzelli, H Gal, E Domany… - Molecular cell, 2008 - cell.com
p73 has been identified as a structural and functional homolog of the tumor suppressor p53.
The transcriptional coactivator Yes-associated protein (YAP) has been demonstrated to …

Direct p53 Transcriptional Repression: In Vivo Analysis of CCAAT-Containing G2/M Promoters

…, A Gurtner, F Cocchiarella, S Di Agostino… - … and cellular biology, 2005 - Taylor & Francis
In response to DNA damage, p53 activates G 1 /S blocking and apoptotic genes through
sequence-specific binding. p53 also represses genes with no target site, such as those for Cdc2 …

YAP enhances the pro‐proliferative transcriptional activity of mutant p53 proteins

S Di Agostino, G Sorrentino, E Ingallina, F Valenti… - EMBO …, 2016 - embopress.org
Mutant p53 proteins are present in more than half of human cancers. Yes‐associated protein
( YAP ) is a key transcriptional regulator controlling organ growth, tissue homeostasis, and …

[HTML][HTML] Mutant p53 stimulates chemoresistance of pancreatic adenocarcinoma cells to gemcitabine

…, C Padroni, G Blandino, S Di Agostino… - … et Biophysica Acta (BBA …, 2015 - Elsevier
Pancreatic adenocarcinoma (PDAC) is the fourth leading cause of cancer-related deaths
worldwide; PDAC is characterized by poor prognosis, resistance to conventional chemotherapy …

[HTML][HTML] Mutant p53 proteins counteract autophagic mechanism sensitizing cancer cells to mTOR inhibition

…, B Cellini, G Blandino, M Palmieri, S Di Agostino… - Molecular …, 2016 - Elsevier
Mutations in TP53 gene play a pivotal role in tumorigenesis and cancer development. Here,
we report that gain-of-function mutant p53 proteins inhibit the autophagic pathway favoring …

Signaling through extracellular signal-regulated kinase is required for spermatogonial proliferative response to stem cell factor

S Dolci, M Pellegrini, S Di Agostino, R Geremia… - Journal of Biological …, 2001 - jbc.org
In vitro addition of stem cell factor (SCF) to c-kit-expressing A 1 –A 4 spermatogonia from
prepuberal mice stimulates their progression into the mitotic cell cycle and significantly reduces …
