Ribonucleotide reductase M1 subunit in cellular proliferation, quiescence, and differentiation.
Ribonucleotide reductase catalyzes the first unique, rate-limiting step in DNA synthesis; both its large (M1) and small (M2) subunits are necessary for activity. While direct studies of M2 expression have previously shown a tight correlation with S phase, the kinetic features of M1-expressing cells have remained ill defined. Therefore we have, using immunofluorescence flow cytometry, analyzed c...
متن کاملTargeting ribonucleotide reductase M2 subunit by small interfering RNA exerts anti-oncogenic effects in gastric adenocarcinoma.
Ribonucleotide reductase M2 subunit (RRM2) is one of the two subunits of human ribonucleotide reductase which plays a critical role in tumor progression. The aim of the present study was to analyze its expression, clinical significance and biological functions in gastric adenocarcinoma. We observed the upregulation of RRM2 mRNA and protein in all nine gastric cancer cell lines examined. In pair...
متن کاملRegulation of ribonucleotide reductase M2 expression by the upstream AUGs
Ribonucleotide reductase catalyzes a rate-limiting reaction in DNA synthesis by converting ribonucleotides to deoxyribonucleotides. It consists of two subunits and the small one, M2 (or R2), plays an essential role in regulating the enzyme activity and its expression is finely controlled. Changes in the M2 level influence the dNTP pool and, thus, DNA synthesis and cell proliferation. M2 gene ha...
متن کاملTargeting Ribonucleotide Reductase M2 and NF-κB Activation with Didox to Circumvent Tamoxifen Resistance in Breast Cancer.
Tamoxifen is widely used as an adjuvant therapy for patients with estrogen receptor (ERα)-positive tumors. However, the clinical benefit is often limited because of the emergence of drug resistance. In this study, overexpression of ribonucleotide reductase M2 (RRM2) in MCF-7 breast cancer cells resulted in a reduction in the effectiveness of tamoxifen, through downregulation of ERα66 and upregu...
متن کاملTargeting BRAF in multiple myeloma.
In multiple myeloma, it is believed that multiple mutations in different pathways deregulate the intrinsic biology of the plasma cell, resulting in a genetically complex heterogeneous disease. Mutations in the mitogen-activated protein kinase/extracellular signal-regulated kinase pathway have been identified and represent potential targets for therapy in this disease. BRAF, a serine/threonine k...
