Abstract: The present invention relates to a method of purifying high-purity ubiquitin without acid or heat treatment. The method presented here is designed to overcome limitations of acid or heat based ubiquitin purification in two different points of view.
First, it decreases a chance of mixing other proteins resistant to acids or heat. Second, it includes no harsh condition, which might denature the ubiquitin. As a result, the purification of native ubiquitin becomes possible. The ubiquitin obtained herein is expected to be used for various purposes in technical fields.-

Abstract: The present invention relates to a composition for treating bladder cancer, which includes a methylation inhibitor of the Sonic hedgehog (SHH) gene, and more particularly, to a composition for preventing or treating bladder cancer, which includes a methylation inhibitor as an active ingredient to activate a hedgehog (Hh) signaling pathway involving a protein encoded by the gene by maintaining the expression level of SHH gene by suppressing methylation at the specific sites of the promoter of the SHH gene.
The inventors found that the methylation at specific sites of the promoter of the SHH gene changes the pattern of the gene expression, and first identified that bladder cancer can be prevented or treated by controlling the Hh signaling pathway involving a protein encoded by the gene. Therefore, since the growth of cancer cells may be inhibited by inducing differentiation of the bladder cancer cells to a luminal subtype by activating the Hh signaling pathway by suppressing the methylation of the promoter of the SHH gene, the composition according to the present invention is expected to be effectively used in the treatment of bladder cancer.-

Abstract: Provided is a method of transmitting security information of a single-bit analog-to-digital converter (ADC) wiretap channel. In the method of transmitting the security information of the single-bit ADC channel, a transmitting terminal adds additive noise to a transmission signal and transmits the transmission signal, and a receiving terminal and a wiretap terminal which each include a single-bit ADC receive the transmission signal, wherein received information is processed so as not to be determined by the wiretap terminal. When intensity of additive noise of the receiving terminal is less than that of additive noise of the wiretap terminal, a binary phase-shift keying (BPSK) distribution is used, and when the intensity of the additive noise of the receiving terminal is greater than that of the additive noise of the wiretap terminal, a codebook is designed using an asymmetric BPSK distribution in which both of two message points have a positive value.
