The mitochondrial DNA (mtDNA) mutations in mitochondrial coding and non coding regions seem to be important in carcinogenesis. The aim of this investigation was to evaluate coding region (mt-tRNA(Phe) and tRNA(Pro)) and non-coding sequence, mitochondrial displacement loop (mtDNA D-loop), in the cancerous and non-cancerous lesions of Iranian patients with breast cancer (BC). Genomic DNA was extr...

abstractintroduction: cancer is caused by genetic abnormalities, such as mutation of ontogenesis or tumor suppressor genes which alter downstream signaling pathways and protein-protein interactions. comparison of protein interactions in cancerous and normal cells can be of help in mechanisms of disease diagnoses and treatments. methods: we constructed protein interaction networks of cancerous a...

5-hydroxymethylcytosine (5-hmC) is a modified form of cytosine recently found in mammalians and is believed, like 5-methylcytosine, to also play an important role in switching genes on and off. By utilizing a newly developed 5-hmC immunoassay, we determined the abundance of 5-hmC in human tissues and compared 5-hmC states in normal colorectal tissue and cancerous colorectal tissue. Significant ...

Objective: To analyze the expression of glutaminase 1 (GLS1) gene in breast cancer and its clinical significance in neoadjuvant chemotherapy. Methods: A total of 134 female patients with breast cancer who were treated in Department of Thyroid and Breast Surgery, Nanjing Drum Tower Hospital were selected. After being diagnosed by biopsy, they were randomly divided into two groups (n=67). Before ...

BACKGROUND On the past decade a plethora of investigations were directed on identification of molecules involved in breast tumorogenesis, which could represent a powerful tool for monitoring, diagnostics and treatment of this disease. In current study we analyzed six previously identified medullary breast carcinoma autoantigens including LGALS3BP, RAD50, FAM50A, RBPJ, PABPC4, LRRFIP1 with cance...

Demonstrated a reliable distinction in the emission and circular dichroism spectral features of TO dye, on binding to DNAs from non-cancerous cancerous tissues, which offers label-free optical method for diagnosis cancer tissues.

The development of ectopic breast tissue is attributable to the failure of primitive mammary tissue to regress after the development of the mammary ridge, except at pectoral breast sites, and is most often evident in the axillae. Several benign and malignant breast diseases have been reported in ectopic axillary breast tissues. The most common cancerous pathology of ectopic breast tissue is inv...

Objective: In traditional medicine, Ficus carica (also known as fig) latex is recognized as a remedy with various therapeutic effects. Recently, in vitro studies have reported the anticancer effect of this latex on cancer cell lines. This study evaluated the effect of this latex on breast cancer growth, hematological parameters, and histopathology in rats. Materials and Methods: Twenty-four fem...

ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....
