FIRRM cooperates with FIGNL1 to promote RAD51 disassembly during DNA repair.

Interstrand DNA cross-links (ICLs) represent complex lesions that compromise genomic stability. Several pathways have been involved in ICL repair, but the extent of factors involved in the resolution of ICL-induced DNA double-strand breaks (DSBs) remains poorly defined. Using CRISPR-based genomics, we identified FIGNL1 interacting regulator of recombination and mitosis (FIRRM) as a sensitizer of the ICL-inducing agent mafosfamide.

[Chronic cough. Cough reflex hypersensitivity syndrome].

The cough reflex is a protective mechanism of the airway; it avoids bronchoaspiration and its complications and, when it is altered, it can appear as a hypersensitivity syndrome; cough per se is the most common symptom for which medical consultation is sought. Chronic cough represents a public health problem with a high degree of morbidity; It represents a syndrome by itself, regardless of the underlying condition. Recent evidence suggests an abnormal and altered neurophysiologic process.

Binding of the regulatory domain of MutL to the sliding β-clamp is species specific.

The β-clamp is a protein hub central to DNA replication and fork management. Proteins interacting with the β-clamp harbor a conserved clamp-binding motif that is often found in extended regions. Therefore, clamp interactions have -almost exclusively- been studied using short peptides recapitulating the binding motif.

Primary cutaneous CD8+ and CD30+ T-cell lymphoproliferative disorders: case reports and clinical implications.

Background: CD8+ CD30+ primary cutaneous T-cell lymphomas (PCTCL) are rare entities with overlapping pathological features and variable outcome.

Objectives: We sought to highlight the importance of correlation between pathological findings and clinical presentation for correct classification of the disease.

Materials & Methods: Two cases of CD8+ CD30+ PCTCL were investigated.
