The architectural transcription factor HMGA2 is abundantly expressed during embryonic development. In several malignant neoplasias including prostate cancer, high re-expression of HMGA2 is correlated with malignancy and poor prognosis. The let-7 miRNA family is described to regulate HMGA2 negatively. The balance of let-7 and HMGA2 is discussed to play a major role in tumour aetiology. To furthe...

Epithelial-to-mesenchymal transition (EMT) is an important event during tumorigenesis. The human high-mobility group A2 (HMGA2) is a chromatin-binding protein, which contains three AT-hook domains that enable its binding to the minor groove of DNA. HMGA2 organizes protein complexes on enhancers of various genes to regulate gene expression and cell differentiation. The HMGA2 protein has been rep...

The high-mobility group AT-hook 2 (HMGA2) protein is a member of the high-mobility group family of the DNA-binding architectural factors and participates in the conformational regulation of active chromatin on its specific downstream target genes. HMGA2 is expressed in the undifferentiated mesenchyme and is undetectable in their differentiated counterparts, suggesting its functional importance ...

High-mobility group AT-hook 2 (HMGA2), a member of the high mobility group family, has been reported to correlate with cancer progression. However, there is no report concerning the correlation between HMGA2 and metastasis in renal cell carcinoma. In the present study, we found that HMGA2 was highly expressed in five renal cell carcinoma cell lines compared with that in the normal renal tubular...

Hmga2 protein belongs to the non-histone chromosomal high-mobility group (HMG) protein family. HMG proteins have been shown to function as architectural transcription regulators, facilitating enhanceosome formation on a variety of mammalian promoters. Hmga2 are expressed at high levels in embryonic and transformed cells. Terminally differentiated cells, however, have been reported to express on...

High mobility group AT-hook 2 (HMGA2) is an architectural transcription factor that is negatively regulated by let-7 microRNA through binding to it's 3'-untranslated region. Transgenic mice expressing Hmga2 with a truncation of its 3'-untranslated region has been shown to exhibit a myeloproliferative phenotype. To decipher the let-7-HMGA2 axis in myeloproliferative neoplasms, we employed an in ...

Trisomy of chromosome 12 is a nonrandom chromosomal change in pituitary adenomas, particularly prolactinomas. This and the finding that prolactin-secreting pituitary adenomas develop in transgenic mice overexpressing the wild-type HMGA2 gene (which maps to 12q14-15) prompted us to investigate HMGA2 rearrangements and expression in human prolactinomas. By dual-color interphase fluorescence in si...

Previously, the human high mobility group protein member HMGA2 mRNA was reported to be expressed in peripheral blood of patients with breast cancer, but not in healthy individuals. Expression of HMGA2 in blood was suggested to be an independent indicator of poor prognosis in metastatic breast cancer. These very promising findings propose HMGA2 as a potential marker for the detection of circulat...

High-mobility group AT-hook 2 (HMGA2) is involved in a wide spectrum of biological processes and is upregulated in several tumors, but its role in renal carcinoma remains unclear. The aim of this study was to examine the expression of HMGA2 and its relationship to the overall survival (OS) of patients with non-metastatic clear cell renal cell carcinoma (ccRCC) following surgery. The expression ...
