Dr. Hans-Juergen Schulten studied biology from 1989 to 1994 with the major in microbiology and the minor in biochemistry and ecology at the Technical University of Braunschweig, Germany. From 1995 to 1998 he performed his doctoral study at the Institute of Human Genetics, University of Goettingen, Germany. In his thesis he worked on the transcriptional and translational regulation of the developmental proacrosin gene using in vitro and in vivo techniques. The proacrosin gene was a candidate gene for male infertility. His molecular genetic findings were published (J Cell Biochem. 2001;83:155-62) (Biochem Biophys Res Commun. 1999;257:871-3). From 1999 to 2007 he worked as a postdoc at the Gastroenteropathology Department of the University of Goettingen in the field of molecular cytogenetics on solid human tumors. Dr. Schulten contributed to a number of molecular cytogenetic studies in the field of gynecology, i.e. characterization of Malignant Mixed Müllerian tumors of the uterus (Anticancer Res.2003;23:1379-84); breakpoint mapping of a endometrial stromal sarcoma cell line (Cancer Genet Cytogenet. 2003;147:84-6.); comparative genomic hybridization study on carcinosarcomas and endometrial adenosarcomas (Am J Clin Pathol. 2004;122:546-51.); multicolor FISH on a choriocarcinoma/trophoblast hybrid (Hum Pathol. 2004;35:1427-30); and characterization of an established uterine carcinosarcoma cell line (Int J Gynecol Cancer. 2008;18:339-44). Since 2009 Dr. Schulten is working at the Center of Excellence in Genomic Medicine Research in Jeddah, Saudi Arabia where he is working in a number of molecular genetic studies.
