Publication number: 20220228165Abstract: The present disclosure relates to a DNA construct, and a strain into which a recombinant vector comprising the DNA construct has been introduced. The DNA construct according to the present disclosure allows the expression levels of genes, operably linked downstream of first and second promoters, in a host strain or cell, to be balanced, so that cancer diagnosis and treatment may be performed simultaneously. In addition, the DNA construct of the present disclosure completely does not allow the anticancer protein and the reporter protein to be expressed at all in the absence of doxycycline, and thus it allows the anticancer protein to be expressed at an appropriate dose for cancer treatment by controlling whether or not treatment with doxycycline is performed, and at the same time, enables the size of the cancer to be monitored in real time depending on the expression level of the reporter protein.Type: ApplicationFiled: May 11, 2020Publication date: July 21, 2022Inventors: Jung Joon Min, Hyon El Choy, Yeong Jin Hong, Sung Hwan You, Mi Ryung Song

Patent number: 10130712Abstract: A drug delivery system composition includes Corynebacterium sp. bacteria or Corynebacterium sp. bacteria-derived minicells. The drug delivery system composition is safer for use in human bodies than other bacteria (for example, Escherichia coli (E. coli), Salmonella sp. bacteria, Bacillus sp. bacteria, or the like), or other bacteria-derived drug delivery system. When an anti-cancer drug protein expression construct (protein expression recombinant vector or the like) is included, over-expression of an anti-cancer drug protein, effective protein expression control in vivo, and targeting technique using expression of targeting factor. The drug delivery system composition enables stable drug delivery in vivo, thereby maximizing anti-cancer therapeutic effects.Type: GrantFiled: October 21, 2015Date of Patent: November 20, 2018Assignee: INDUSTRY FOUNDATION OF CHONNAM NATIONAL UNIVERSITYInventors: Geun Joong Kim, Jin-Young Lee, Sa-Young Min, Sung-Hwan You, Jung-Joon Min
