20080286238Recombinant Adenovirus Expressing A Gene Encoding Streptolysin O Proetin and Anti-Cancer Composition Comprising Same - A recombinant adenovirus expressing a streptolysin O (SLO) protein comprising a SLO gene; a promoter operably linked to the SLO gene; a polyadenylation signal sequence; and an adenovirus genome lacking E1 gene effectively kills a cancer cell by expressing a pore-forming toxin, SLO protein, and, therefore, is useful for the suicide cancer gene therapy.11-20-2008
20090189652Frequency Multiplier - A frequency multiplier is disclosed. A plurality of voltage regulators each regulate levels of voltages at first and second common nodes in response to a corresponding one of input signals from a voltage-controlled delay line. An input buffer charges the first node or discharges the second node in response to a feedback signal. An output buffer regulates a level of a voltage at an output node and outputs a frequency-multiplied clock signal and the feedback signal corresponding to the voltage level of the output node. A discharge circuit discharges the first node before a rising edge of each of the input signals from the voltage-controlled delay line is inputted. A charge circuit charges the second node before the rising edge of each of the input signals from the voltage-controlled delay line is inputted.07-30-2009
20090202623GENE THERAPY FOR CANCER USING SMALL INTERFERING RNA SPECIFIC TO ANT2 AND A METHOD TO OVERCOME TOLERANCE TO ANTITUMOR AGENT - The present invention relates to a small interfering RNA (siRNA) suppressing the expression of adenine nucleotide trnaslocator 2 (ANT2) gene and an anticancer agent containing the same. Particularly, the invention relates to ANT2 siRNA comprising a sense sequence selected from the nucleotide sequences of ANT2 mRNA, a hairpin loop sequence and an antisense sequence binding complementarily to the said sense sequence and an anticancer agent containing the same. ANT2 siRNA of the present invention inhibits the expression of ANT2 gene, suggesting that it inhibits the growth of cancer cells exhibiting high level of ANT2. Therefore, ANT2 siRNA of the invention can be effectively used for gene therapy for cancer treatment and further prevents the anticancer effect from decreasing by anticancer drug resistance of cancer cells.08-13-2009
