Nuclear phosphoproteins HMGA and their relationship with chromatin structure and cancer

TL;DR: The structural characteristics of the three nuclear phosphoproteins of the high mobility group A family are outlined and related to their participation in chromatin structure alteration in many biological processes such as gene expression, neoplastic transformation, differentiation, and apoptosis are outlined.
Journal ArticleDOI

Transcriptional activation of the cyclin A gene by the architectural transcription factor HMGA2.

TL;DR: It is shown that HMGA2 associates with the E1A-regulated transcriptional repressor p120E4F, interfering with p120 E4F binding to the cyclin A promoter, suggesting a mechanism forHMGA2-dependent cell cycle regulation.
Journal ArticleDOI

Proneural-Mesenchymal Transition: Phenotypic Plasticity to Acquire Multitherapy Resistance in Glioblastoma

TL;DR: This review frame this process in the high degree of phenotypic inter- and intra-tumor heterogeneity of GBM, which exists in different subtypes, each one characterized by further phenotypesic variability in its stem-cell compartment under the selective pressure of different treatment agents PMT.
Journal ArticleDOI

HMGA1 promotes metastatic processes in basal-like breast cancer regulating EMT and stemness.

TL;DR: It is shown that the High Mobility Group A1 (HMGA1) protein plays a fundamental role in this process in basal-like breast cancer subtype, and a specific HMGA1 gene expression signature was identified that was activated in a large subset of human primary breast tumours and was associated with poor prognosis.
