Breast cancer is a major health burden, responsible for >10% of all cases of cancer worldwide. Advances in breast cancer diagnosis and treatment have contributed to an improved rate of survival, although mortality rates remains significantly high. The establishment of breast cancer cell lines is an
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has been widely used as a control RNA in Northern blotting and in reverse transcriptase-polymerase chain reaction (RT-PCR) analyses. We investigated the expression of GAPDH in a large series of primary breast cancers and in MCF7 human mammary
Hypoxia up-regulates the expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in a cell type-specific manner. It is unknown whether this occurs in breast cancer. Here, we report that hypoxia up-regulates the GAPDH gene expression through breast cancer-specific molecular mechanisms in MCF-7
AIMS
To determine the expression of the cyclooxygenase-2 (
COX-2) gene in patients with
breast cancer attended at the Centro Universitário Saúde ABC/Faculdade de Medicina do ABC (CUS-ABC/FMABC) outpatient clinic.
Breast cancer is the most common cancer in women worldwide.
BACKGROUND
Telomerase activity has been significantly associated with nodal metastasis and cellular proliferation in human breast cancer, indicating that its degree of expression has some form of vital control over the invasive nature of the malignancy concerned. Of the telomerase subunits, the
BACKGROUND
We analysed cell-free DNA (cfDNA) in the plasma of patients with both malignant and benign breast lesions by real-time quantitative PCR to determine whether the finding may have diagnostic and prognostic implications.
METHODS
Plasma samples were obtained from 33 patients with breast
The main intention of this study was the investigation of impact of natural biologically active ligands of nuclear retinoid/retinoid X receptors (all-trans and 9-cis retinoic acid) on proteomic pattern in human estrogen receptor negative breast cancer cell line MDA-MB-231. For this purpose,
The effects of immunosuppressants and inhibitors of specific calcium/calmodulin kinase (CaMK) of types II and IV on progestin/glucocorticosteroid-induced transcription were studied in two human stably transfected breast cancer T47D cell lines. The lines contain the chloramphenicol acetyl transferase
In situ hybridization analysis provides a means to qualitatively study the heterogeneity of primary tumors and metastases based on the types of genes transcribed. In this study, we have tested some parameters for quantitative analysis of in situ hybridizations with paraffin-embedded human breast
Triple‑negative breast cancer (TNBC) is a heterogeneous disease characterized by an aggressive phenotype and reduced survival. The aim of the present study was to investigate the molecular mechanisms involved in the carcinogenesis of TNBC and to identify novel target molecules for therapy. The
BACKGROUND
Cyclin-dependent kinase 2-associated protein 1 (CDK2AP1) interacts with CDK2AP2, modulates the actions of transforming growth factor-B1, cyclin-dependent kinase 2 and retinoblastoma protein, and closely interacts with micro-RNA21 and micro-RNA25. Our objective was to determine if CDK2AP1
Several clinical studies have suggested that the content of estrogen receptor (ER) in breast tumors influences the survival, tumor recurrence, and response to antiestrogen therapies. Therefore, the ability to precisely quantitate the ER content in tumor tissues will be of significant benefit to
BACKGROUND
BRCA1 is involved in numerous essential processes in the cell, and the effects of BRCA1 dysfunction in breast cancer carcinogenesis are well described. Many of the breast cancer susceptibility genes such as BRCA2, p53, ATM, CHEK2, and BRIP1 encode proteins that interact with BRCA1. BCL6
Gene therapy clinical trials for cancer frequently produce inconsistent results. Some of this variability could result from differences in transcriptional regulation that limit expression of therapeutic genes in specific cancers. Systemic liposomal delivery of a nonviral plasmid DNA showed efficacy
OBJECTIVE
In order to assess the potential biomolecules for breast cancer, we analyzed in parallel the levels of cell-free glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and cell-free nucleosomes in serum samples from patients with benign and malignant breast tumors. The levels of cell-free DNA
