Background: Overexpression of Rad51 protein in many tumor cells has been proven to increase radioresistance and can be related to the resistance of chemosensitivity of tumor cells. This preliminary study was conducted to determine the relationship between the Rad51 expression level in nasopharyngeal carcinoma and the response of the treatment based on the measurement o...

The role of Rad51 protein in radioresistance of spheroid model of DU145 prostate carcinoma cell line
Background: Rad51 is a protein with critical role in double strand break repair. Down-regulation of this protein has a significant effect in radiosensitivity of some cell lines like prostate carcinoma. Compared to monolayer cell culture model, the spheroids are more resistant to radiation. The aim of the current study was to determine the Rad51 protein level in DU145 spheroids, and monol...
background rapid dose assessment using biological dosimetry methods is essential to increase the chance of survival of exposed individuals in radiation accidents. objectives we compared the expression levels of the fdxr and rad51 genes at 6 and 18 mv beam energies in human peripheral blood lymphocytes. the results of our study can be used to analyze radiation energy in biological dosimetry. con...

Expression of RAD51, a crucial player in homologous recombination (HR) and DNA double-strand break (DSB) repair, is dysregulated in human tumors, and can contribute to genomic instability and tumor progression. To further understand RAD51 regulation we functionally characterized a long non-coding (lnc) RNA, dubbed TODRA (Transcribed in the Opposite Direction of RAD51), transcribed 69bp upstream...
RAD51, an essential eukaryotic DNA recombinase, promotes homologous pairing and strand exchange during homologous recombination and the recombinational repair of double strand breaks. Mutations that up- or down-regulate RAD51 gene expression have been identified in several tumors, suggesting that inappropriate expression of the RAD51 activity may cause tumorigenesis. To identify chemical compou...
Rad51 is an essential component of the homologous DNA repair pathway and has been implicated as a determinant of cellular radiosensitivity. Gleevec is a relatively specific inhibitor of c-Abl, a tyrosine kinase that can play a role in the regulation Rad51. The aim of this study was to determine the effects of Gleevec on Rad51 levels and the radiosensitivity of two human glioma cell lines and a ...
BACKGROUND Aberrant Rad51 expression is implicated in the progression of human malignancies. However, the role of Rad51 in colorectal cancer (CRC) remains undefined. This study aimed to establish a relationship between Rad51 and clinicopathologic features of CRC. METHODS We retrospectively examined the paraffin-embedded tissue samples obtained from 54 patients with CRC who had received surgic...
We investigated whether Rad51 overexpression plays a role in soft tissue sarcoma (STS) chemoresistance as well as the regulatory mechanisms underlying its expression. The studies reported here show that Rad51 protein is overexpressed in a large panel of human STS specimens. Human STS cell lines showed increased Rad51 protein expression, as was also observed in nude rat STS xenografts. STS cells...
