Is thoracic endometriosis syndrome strongly associated with severe pelvic endometriosis and infertility?
Thoracic endometriosis syndrome, represented by catamenial pneumothorax, was strongly associated with severe pelvic endometriosis and a high rate of infertility. Inasmuch as many patients with thoracic endometriosis syndrome are treated by thoracic surgeons using video-assisted thoracoscopy, it is desirable to involve an experienced gynecologist who can diagnose and treat concurrent pelvic endometriosis.
Our data indicate that human Scc4 is required for the association of cohesin with chromatin, which is a prerequisite for the establishment of sister-chromatid cohesion and for chromosome biorientation in mitosis. The proteinaceous machinery that is required for loading of cohesin onto chromatin is therefore conserved from yeast to humans. The finding that Caenorhabditis elegans MAU-2 is an ortholog of Scc4 further supports the notion that the Scc2-Scc4 complex is required for developmental processes in metazoans.
