OBJECTIVE
To study the relation between SUVmax, hypoxia inducible factor 1α (HIF-1α), angiogenetic factor adrenomedullin (AM) and antiapoptotic factor Bcl-2 in endometrial cancer.
METHODS
Thirthy eight patients who were diagnosed after a preoperative endometrial biopsy with endometrium cancer
Hypoxia-inducible factor-1α (HIF-1α), glucose transporter-1 (GLUT-1), and carbon anhydrase IX (CAIX) are important molecules that allow adaptation to hypoxic environments. The aim of our study was to investigate the correlation between HIF-1α, GLUT-1, and CAIX protein level with the
OBJECTIVE
Angiogenesis is essential for the development, growth and advancement of solid tumors. Angiogenesis is induced by hypoxia with the angiogenic transcription factor hypoxia-inducible factor (HIF). This prompted us to study the clinical implications of HIF relative to angiogenesis in uterine
Objective: To reduce the stemness maintenance ability of endometrial cancer stem cell and increase its sensitivity to chemotherapy by inducing hypoxia inducible factor 1α (HIF-1α) protein deSUMOylation. Methods: Lentiviral plasmid mediated ubiquitin carrier protein 9 (Ubc9) gene silencing was
Recent data support a role for SHARP1, a basic helix-loop-helix transcription repressor, in the regulation of malignant cell behavior in several human cancers. However, the expression and role of SHARP1 during the development of endometrial cancer (EC) remain unclear. Here we show that upregulation
BACKGROUND
Endometral carcinoma is the most common malignant tumor of the female genital tract and the fourth most common cancer in women after breast, colorectal and lung cancers Hypoxia-inducible factor -1 (HIF-1) is a key transcription factor that regulates cellular response to hypoxia HIF-1
BACKGROUND
DNA sequence variations in HIF-1 alpha gene might yield changes both in the production outcomes and in the activities of the gene. Overexpression of the HIF-1 alpha subunit, resulting from intratumoral hypoxia and genetic alterations, has been demonstrated in common human cancers and is
High expression of Ki67, a proliferation marker, is associated with reduced endometrial cancer-specific survival. Pre-surgical metformin reduces tumour Ki-67 expression in some women with endometrial cancer. Metformin's anti-cancer activity may relate to effects on cellular energy OBJECTIVE
BNIP3 is a pro-apoptotic mitochondrial protein induced under hypoxic stress, with the BNIP3 gene being under direct regulation of the hypoxia-inducible HIF-1alpha transcription factor. Induction of BNIP3 leads to caspase-independent necrosis-like cell death and an aggressive tumour
Hypoxia is frequent in solid tumors and linked to aggressive phenotypes and therapy resistance. We explored expression patterns of the proposed hypoxia marker HIF-1α in endometrial cancer (EC) and investigate whether preoperative functional imaging parameters are associated with tumor hypoxia.
Proline hydroxylase 2 (PHD2) is involved in tumorigenesis. This study aimed to examine PHD2 and hypoxia-inducible factor 1α (HIF-1α) expression in different endometrial tissues and explore the correlations between PHD2 and HIF-1α expression with clinicopathological characteristics of Due to their post-transcriptional regulatory impact on gene expression, microRNAs (miRNA, miRs) influence decisively cellular processes of differentiation, proliferation and apoptosis. In oncogenic pathways various miRNAs exert either oncogenic or tumor suppressor activities in a stage-specific
Recent studies suggested that Ob (Ob) and its receptor (ObR) could be involved in the pathogenesis of various human malignancies, among others in endometrial cancer. Moreover, hypoxia, which is associated with solid tumors, might stimulate, through hypoxia-inducible factor 1alpha (HIF-1alpha),
In the Western world, endometrial cancer (EC) is the most common malignant tumor of the female genital tract. Solid tumors like EC outgrow their vasculature resulting in hypoxia. Tumor hypoxia is important because it renders an aggressive phenotype and leads to radio- and chemo-therapy resistance.
OBJECTIVE
Tumor necrosis is associated with aggressive features of endometrial cancer and poor prognosis. Here, we investigated gene expression patterns and potential treatment targets related to presence of tumor necrosis in primary endometrial cancer lesions.
RESULTS
By DNA microarray analysis,
