Glutamine, MTOR and autophagy: a multiconnection relationship
(Taylor & Francis, 2022)
Cancer cells metabolize glutamine mostly through glutaminolysis, a metabolic pathway that activates MTORC1. The AMPK-MTORC1 signaling axis is a key regulator of cell growth and proliferation. Our recent investigation ...

Thyroid hormones in diabetes, cancer, and aging
(Wiley, 2020)
Thyroid function is central in the control of physiological and pathophysiological processes. Studies in animal models and human research have determined that thyroid hormones modulate cellular processes relevant for aging ...

Harmful R-loops are prevented via different cell cycle-specific mechanisms
(Springer Nature, 2021)
Identifying how R-loops are generated is crucial to know how transcription compromises genome integrity. We show by genome-wide analysis of conditional yeast mutants that the THO transcription complex, prevents R-loop ...

A transcription-based mechanism for oncogenic β-catenin-induced lethality in BRCA1/2-deficient cells
(Springer Nature, 2021)
BRCA1 or BRCA2 germline mutations predispose to breast, ovarian and other cancers. High-throughput sequencing of tumour genomes revealed that oncogene amplification and BRCA1/2 mutations are mutually exclusive in cancer, ...

CtIP-mediated Alternative mRNA Splicing Fine-tunes the DNA Damage Response
(Cold Spring Harbor Laboratory Press, 2021)
In order to survive to the exposure of DNA damaging agents, cells activate a complex response that coordinates the cellular metabolism, cell cycle progression, and DNA repair. Among many other events, recent evidence has ...

ATRX-Deficient High-Grade Glioma Cells Exhibit Increased Sensitivity to RTK and PDGFR Inhibitors
(MDPI, 2022)
High-grade glioma, including anaplastic astrocytoma and glioblastoma (GBM) patients, have a poor prognosis due to the lack of effective treatments. Therefore, the development of new therapeutic strategies to treat these ...

DDX47, MeCP2, and other functionally heterogeneous factors protect cells from harmful R loops
(Elsevier, 2023)
Unscheduled R loops can be a source of genome instability, a hallmark of cancer cells. Although targeted proteomic approaches and cellular analysis of specific mutants have uncovered factors potentially involved in R-loop ...

Distinct responses of human peripheral blood cells to different misfolded protein oligomers
(Wiley-Blackwell, 2021)
Increasing evidence indicates that peripheral immune cells play a prominent role in neurodegeneration connected to protein misfolding, which are associated with formation of aberrant aggregates, including soluble protein ...

Looping the (R) Loop in DSB Repair via RNA Methylation
(Elsevier, 2020)
In this issue of Molecular Cell, Zhang et al. (2020) reveal that ATM triggers RNA methylation of DNA-RNA hybrids formed at double-strand breaks (DSBs) to modulate repair, adding a new layer of complexity to RNA's role in ...

XRCC1 Prevents Replication Fork Instability during Misincorporation of the DNA Demethylation Bases 5-Hydroxymethyl-2′-Deoxycytidine and 5-Hydroxymethyl-2′-Deoxyuridine
(MDPI, 2022)
Whilst avoidance of chemical modifications of DNA bases is essential to maintain genome stability, during evolution eukaryotic cells have evolved a chemically reversible modification of the cytosine base. These dynamic ...
