Exon–Intron differential analysis reveals the role of competing endogenous RNAs in post-transcriptional regulation of translation

Munz, Nicolas ; Cascione, Luciano ; Parmigiani, Luca ; Tarantelli, Chiara ; Rinaldi, Andrea ; Cmiljanovic, Natasa ; Cmiljanovic, Vladimir ; Giugno, Rosalba ; Bertoni, Francesco ; Napoli, Sara

In: Non-coding RNA, 2021, vol. 7, no. 2, p. 13

Stressful conditions induce the cell to save energy and activate a rescue program modulated by mammalian target of rapamycin (mTOR). Along with transcriptional and translational regulation, the cell relies also on post-transcriptional modulation to quickly adapt the translation of essential proteins. MicroRNAs play an important role in the regulation of protein translation, and their...

Role of ETS1 in the transcriptional network of diffuse large B cell lymphoma of the activated B cell-like type

Priebe, Valdemar ; Sartori, Giulio ; Napoli, Sara ; Chung, Elaine Yee Lin ; Cascione, Luciano ; Kwee, Ivo ; Arribas, Alberto Jesus ; Mensah, Afua Adjeiwaa ; Rinaldi, Andrea ; Ponzoni, Maurilio ; Zucca, Emanuele ; Rossi, Davide ; Efremov, Dimitar ; Lenz, Georg ; Thome, Margot ; Bertoni, Francesco

Diffuse large B cell lymphoma (DLBCL) is a heterogenous disease that has been distinguished into at least two major molecular entities, the germinal center-like B cell (GCB) DLBCL and activated-like B cell (ABC) DLBCL, based on transcriptome expression profiling. A recurrent ch11q24.3 gain is observed in roughly a fourth of DLBCL cases resulting in the overexpression of two ETS transcription...

Influenza vaccination induces NK-cell-mediated type-II IFN response that regulates humoral immunity in an IL-6-dependent manner

Farsakoglu, Yagmur ; Palomino-Segura, Miguel ; Latino, Irene ; Zanaga, Silvia ; Chatziandreou, Nikolaos ; Pizzagalli, Diego Ulisse ; Rinaldi, Andrea ; Bolis, Marco ; Sallusto, Federica ; Stein, Jens V. ; Gonzalez, Santiago F.

In: Cell reports, 2019, vol. 26, no. 9, p. 2307-2315.e5

The role of natural killer (NK) cells in the immune response against vaccines is not fully understood. Here, we examine the function of infiltrated NK cells in the initiation of the inflammatory response triggered by inactivated influenza virus vaccine in the draining lymph node (LN). We observed that, following vaccination, NK cells are recruited to the interfollicular and medullary areas of...

Inhibition of Notch pathway arrests PTEN-deficient advanced prostate cancer by triggering p27-driven cellular senescence

Revandkar, Ajinkya ; Perciato, Maria Luna ; Toso, Alberto ; Alajati, Abdullah ; Chen, Jingjing ; Gerber, Hermeto ; Dimitrov, Mitko ; Rinaldi, Andrea ; Delaleu, Nicolas ; Pasquini, Emiliano ; D’Antuono, Rocco ; Pinton, Sandra ; Losa, Marco ; Gnetti, Letizia ; Arribas, Alberto ; Fraering, Patrick ; Bertoni, Francesco ; Nepveu, Alain ; Andrea Alimonti

Activation of NOTCH signalling is associated with advanced prostate cancer and treatment resistance in prostate cancer patients. However, the mechanism that drives NOTCH activation in prostate cancer remains still elusive. Moreover, preclinical evidence of the therapeutic efficacy of NOTCH inhibitors in prostate cancer is lacking. Here, we provide evidence that PTEN loss in prostate tumours ...

Dnmt3a restrains mast cell inflammatory responses

Leoni, Cristina ; Montagner, Sara ; Rinaldi, Andrea ; Bertoni, Francesco ; Polletti, Sara ; Balestrieri, Chiara ; Monticelli, Silvia

In: Proceedings of the national academy of sciences, 2017, vol. 114, no. 8, p. E1490-E1499

DNA methylation and specifically the DNA methyltransferase enzyme DNMT3A are involved in the pathogenesis of a variety of hematological diseases and in regulating the function of immune cells. Although altered DNA methylation patterns and mutations in DNMT3A correlate with mast cell proliferative disorders in humans, the role of DNA methylation in mast cell biology is not understood. By using...

Chemical stresses fail to mimic the unfolded protein response resulting from luminal load with unfolded polypeptides

Bergmann, Timothy J. ; Fregno, Ilaria ; Fumagalli, Fiorenza ; Rinaldi, Andrea ; Bertoni, Francesco ; Boersema, Paul J. ; Picotti, Paola ; Molinari, Maurizio

In: Journal of biological chemistry, 2018, vol. 293, no. 15, p. 5600-5612

The stress sensors ATF6, IRE1, and PERK monitor deviations from homeostatic conditions in the endoplasmic reticulum (ER), a protein biogenesis compartment of eukaryotic cells. Their activation elicits unfolded protein responses (UPR) to reestablish proteostasis. UPR have been extensively investigated in cells exposed to chemicals that activate ER stress sensors by perturbing calcium, N-glycans,...
