The latch modulates nucleotide and DNA binding to the helicase-like domain of Thermotoga maritima reverse gyrase and is required for positive DNA supercoiling [PDF]
Reverse gyrase is the only topoisomerase that can introduce positive supercoils into DNA in an ATP-dependent process. It has a modular structure and harnesses a helicase-like domain to support a topoisomerase activity, thereby creating the unique ...

Double-strand break repair and homologous recombination in Schizosaccharomyces pombe [PDF]
In recent years our understanding of double strand break repair and homologous recombination in Schizosaccharomyces pombe has increased significantly, and the identification of novel pathways and genes with homologues in higher eukaryotes has increased ...

ABSTRACT One of the most serious complications associated with the use of the chemotherapeutic agent doxorubicin (DOX) is cardiomyopathy. Although cardioprotective drugs such as angiotensin receptor‐neprilysin inhibitors (ARNI) are used to prevent cardiomyopathy in DOX patients, no studies have reported the relationship between ARNI and endoplasmic ...

Expression of proliferation-dependent antigens during cellular ageing of normal and progeroid human fibroblasts [PDF]
Normal human fibroblasts display a limited lifespan in culture, which is due to a steadily decreasing fraction of cells that are able to proliferate.

Evaluation of melanin-targeted radiotherapy in combination with radiosensitizing drugs for the treatment of melanoma [PDF]
The incidence of malignant melanoma is rising faster than that of any other cancer in the United States. An [131I]-labeled benzamide - [131I]MIP-1145 - selectively targets melanin, reduces melanoma tumor burden and increases survival in preclinical ...

Mutations in topoisomerase IIβ result in a B cell immunodeficiency. [PDF]
B cell development is a highly regulated process involving multiple differentiation steps, yet many details regarding this pathway remain unknown. Sequencing of patients with B cell-restricted immunodeficiency reveals autosomal dominant mutations in ...
