The long non-coding RNA TAZ-AS202 promotes lung cancer progression via regulation of the E2F1 transcription factor and activation of Ephrin signaling.

Long non-coding RNAs (lncRNAs) are transcripts without coding potential that are pervasively expressed from the genome and have been increasingly reported to play crucial roles in all aspects of cell biology. They have been also heavily implicated in cancer development and progression, with both oncogenic and tumor suppressor functions. In this work, we identified and characterized a novel lncRNA, TAZ-AS202, expressed from the TAZ genomic locus and exerting pro-oncogenic functions in non-small cell lung cancer.

Multiple roles and context-specific mechanisms underlying YAP and TAZ-mediated resistance to anti-cancer therapy.

Understanding the molecular mechanisms driving resistance to anti-cancer drugs is both a crucial step to define markers of response to therapy and a clinical need in many cancer settings. YAP and TAZ transcriptional cofactors behave as oncogenes in different cancer types. Deregulation of YAP/TAZ expression or alterations in components of the multiple signaling pathways converging on these factors are important mechanisms of resistance to chemotherapy, target therapy and hormone therapy.

The Hippo pathway modulates resistance to BET proteins inhibitors in lung cancer cells.

Inhibitors of BET proteins (BETi) are anti-cancer drugs that have shown efficacy in pre-clinical settings and are currently in clinical trials for different types of cancer, including non-small cell lung cancer (NSCLC). Currently, no predictive biomarker is available to identify patients that may benefit from this treatment. To uncover the mechanisms of resistance to BETi, we performed a genome-scale CRISPR/Cas9 screening in lung cancer cells.

Histone Deacetylase Inhibitors Repress Tumoral Expression of the Proinvasive Factor RUNX2.

Aberrant reactivation of embryonic pathways occurs commonly in cancer. The transcription factor RUNX2 plays a fundamental role during embryogenesis and is aberrantly reactivated during progression and metastasization of different types of human tumors. In this study, we attempted to dissect the molecular mechanisms governing RUNX2 expression and its aberrant reactivation.

New insights into the molecular basis of progressive myoclonus epilepsy: a multiprotein complex with cystatin B.

Cystatin B is an anti-proteolytic polypeptide implicated in progressive myoclonus epilepsy (EPM1), a degenerative disease of the central nervous system. The knock-out mouse model of the disease shows apoptosis of the cerebellar granule cells. We have identified five recombinant proteins interacting with cystatin B and none of them is a protease.
