High-mobility group A2 (HMGA2) protein regulates retinoblastoma (RB) cancer cell proliferation. Here, a stable phosphorothioate-modified HMGA2 aptamer was used to block HMGA2 protein function in RB cells. HMGA2-aptamer internalisation in RB cells (Y79, Weri Rb1) and non-neoplastic human retinal cells (MIO-M1) were optimised. Aptamer induced dose-dependent cytotoxicity in RB cancer cells (0.25-1...
Wnt/β-catenin signalling has been suggested to be active in basal-like breast cancer. However, in highly aggressive metastatic triple-negative breast cancers (TNBC) the role of β-catenin and the underlying mechanism(s) for the aggressiveness of TNBC remain unknown. We illustrate that WNT10B induces transcriptionally active β-catenin in human TNBC and predicts survival-outcome of patients with b...
Overexpression of high mobility group AT-hook 2 (HMGA2) is found in a number of benign and malignant tumors, including the clonal PIGA(-) cells in 2 cases of paroxysmal nocturnal hemoglobinuria (PNH) and some myeloproliferative neoplasms (MPNs), and recently in hematopoietic cell clones resulting from gene therapy procedures. In nearly all these cases overexpression is because of deletions or t...
The loss of the tumour suppressor E-cadherin (Cdh1) is a key event during tumourigenesis and epithelial-mesenchymal transition (EMT). Transforming growth factor-β (TGFβ) triggers EMT by inducing the expression of non-histone chromatin protein High Mobility Group A2 (HMGA2). We have previously shown that HMGA2, together with Smads, regulate a network of EMT-transcription factors (EMT-TFs) like S...
OBJECTIVE To determine the mechanism of Angiogenin(ANG) function involved in the carcinogenesis of lung squamous cell carcinoma. METHODS 12 patients' normal tissue and cancerous tissue were collected. ANG expression in the squamous cell carcinoma of the lung was evaluated by qRT-PCR and western-blot. The regulation of ANG on proliferation, migration, invasion, and apoptosis of SK-MES-1 cells ...
DNA-binding and RNA-binding proteins are usually considered 'undruggable' partly due to the lack of an efficient method to identify inhibitors from existing small molecule repositories. Here we report a rapid and sensitive high-throughput screening approach to identify compounds targeting protein-nucleic acids interactions based on protein-DNA or protein-RNA interaction enzyme-linked immunosorb...
BACKGROUND HMGA2 is an architectonic transcription factor abundantly expressed during embryonic and fetal development and it is associated with the progression of malignant tumors. The protein harbours three basically charged DNA binding domains and an acidic protein binding C-terminal domain. DNA binding induces changes of DNA conformation and hence results in global overall change of gene exp...
زمینه و هدف: یکی از علل اصلی مرگ ومیر ناشی از سرطان در مردان، سرطان پروستات می باشد. روش های درمانی متفاوتی برای درمان سرطان پروستات وجود دارد؛ اما بسیاری از بیماران مبتلا به سرطان پروستات از عود بیماری پس از عمل و متاستاز رنج می برند. افزایش بیان 1 hmga2، یک پروتئین انکوژن، در انواع مختلف تومورهای بدخیم از قبیل سرطان کولورکتال، تیروئید، پانکراس، ریه با پیشرفت تومور همراه است. هدف از این مطالعه...
TRIM71 (tripartite motif-containing 71) belongs to the TRIM-NHL protein family, which plays a conserved role in regulating early development and differentiation. However, the molecular functions of TRIM71 have remained largely unknown. Here, we explored the role of TRIM71 together with modulation of Lin28B-let-7-HMGA2 (high-mobility group AT-hook 2) signaling in tumorigenesis. TRIM71 overexpres...
Retinoblastoma (RB) is a primary childhood eye cancer. HMGA2 shows promise as a molecule for targeted therapy. The involvement of miRNAs in genome-level molecular dys-regulation in HMGA2-silenced RB cells is poorly understood. Through miRNA expression microarray profiling, and an integrated array analysis of the HMGA2-silenced RB cells, the dysregulated miRNAs and the miRNA-target relationships...
