The university was formally established in January, 1952 through the union of Gwangju Medical College, Gwangju Agricultural College, Mokpo Commerce College, and Daeseong College. It currently consists of 59 academic departments in 19 colleges and 11 graduate programs. University attached facilities are the University Library, Museum, Health Service Center, Agro-Bioindustry Technical Support Center, Animal Hospital, Language Education Center, School of Lifelong Education, and University Computing Center. In March 2006, Yeosu National University merged with Chonnam National University to become a satellite campus.Chonnam National University used to be generally regarded as one of the five major national universities of South Korea together with Seoul National University, Pusan National University, Kyungpook National University, and Chungnam National University. Now the number of the key national universities has been expanded into ten. CNU is also recognized as one of the best performers in government supported HRD projects. Research expenses of CNU ranks 13th nationally. Moreover, the number of High-ranking public officials ranked 11th. In addition, 26 alumni passed the Second Round of the 51st national bar exam, which is the biggest since the CNU Law School was established. Wikipedia.

A method for preparing a catalyst having catalytically active materials selectively impregnated or supported only in the surface region of the catalyst particle using the mutual repulsive force of a hydrophobic solution and a hydrophilic solution and the solubility difference to a metal salt precursor between the hydrophobic and hydrophilic solutions. The hydrophobic solvent is a C2-C6 alcohol. The hydrophobic solvent is introduced into the catalyst support and then removed of a part of the pores connected to the outer part of the catalyst particle by drying under appropriate conditions. Then, a hydrophilic solution containing a metal salt is introduced to occupy the void spaces removed of the hydrophobic solvent, and the catalyst particle is dried at a low rate to selectively support or impregnate the catalytically active material or the precursor of the catalytically active material only in the outer part of the catalyst particle.

An ultraviolet light emitting device without the use of a p-type semiconductor layer is described. For generating ultraviolet light, an electron beam generator is provided, and an electron beam generated in the electron beam generator is guided to an active layer of an ultraviolet light generator. In the active layer, the electron beam suffers collisions, and electron-hole pairs generated by the collisions are confined in well layers due to barrier layers of the active layer. The confined electrons and holes generate ultraviolet light through recombination.

MicroRNAs are increasingly implicated in the modulation of the progression of various cancers. We previously observed that KAI1 C-terminal interacting tetraspanin (KITENIN) is highly expressed in sporadic human colorectal cancer (CRC) tissues and hence the functional KITENIN complex acts to promote progression of CRC. However, it remains unknown that microRNAs target KITENIN and whether KITENIN-targeting microRNAs modulate CRC cell motility and colorectal tumorigenesis. Here, through bioinformatic analyses and functional studies, we showed that miR-124, miR-27a, and miR-30b negatively regulate KITENIN expression and suppress the migration and invasion of several CRC cell lines via modulation of KITENIN expression. Through in vitro and in vivo induction of mature microRNAs using a tetracycline-inducible system, miR-124 was found to effectively inhibit the invasion of CT-26 colon adenocarcinoma cells and tumor growth in a syngeneic mouse xenograft model. Constitutive overexpression of precursor miR-124 in CT-26 cells suppressed in vivo tumorigenicity and resulted in decreased expression of KITENIN as well as that of MYH9 and SOX9, which are targets of miR-124. Thus, our findings identify that KITENIN-targeting miR-124, miR-27a, and miR-30b function as endogenous inhibitors of CRC cell motility and demonstrate that miR-124 among KITENIN-targeting microRNAs plays a suppressor role in colorectal tumorigenesis.Molecular Therapy (2014); doi:10.1038/mt.2014.105.
