    Abstract: Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer death worldwide. Novel treatment strategies derived from increased knowledge of molecular oncology are constantly being developed to cure this disease. Here, we used phage display to identify novel peptides, including (SP94), which binds specifically to HCC cells. In vitro, the phage clone PC94 binds to HCC cell lines. In vivo, PC94 homed specifically to tumor tissues but not to normal visceral organs in SCID mice bearing human HCC xenografts. The homing ability could be competitively inhibited by synthetic peptide, SP94. PC94 localized to tumor tissues but could not be detected in SP94-competed tumor tissues or in normal organs. In addition, PC94 recognized the tumor tissue but not non-tumor tissue in surgical specimens from HCC patients, with a positive rate of 61.3% (19/31). With the conjugation of SP94 and liposomal doxorubicin, a targeted drug delivery system enhanced the therapeutic efficacy against HCC xenografts through enhanced tumor apoptosis and decreased tumor angiogenesis. Our results indicate that SP94 can improve the systemic treatment of patients with advanced HCC.

    Abstract: PROBLEM TO BE SOLVED: To provide a nucleic acid that can be used to functionally express a heterologous C. rugosa lipase in a common host cell, a lipase having a specific property for industrial applications and a microorganism capable of producing the lipase. SOLUTION: This isolated nucleic acid comprises a mutant DNA encoding a Candida rugosa lipase, wherein the mutant DNA is at least 80% identical to a wild-type DNA encoding the Candida rugosa lipase, and includes at least 12 codons corresponding to CTG codons in the wild-type DNA, each of the 12 codons, independently, being TCT, TCC, TCA, TCG, AGT, or AGC. A chimeric Candida rugosa lipase comprises a substrate interacting domain of a first C. rugosa lipase and a non-substrate interacting domain of a second C. rugosa lipase. This C. rugosa lipase is encoded by the nucleic acid. This microorganism comprises the nucleic acid.

    Abstract: PROBLEM TO BE SOLVED: To obtain a transgenic plant producing seeds useful as a raw material for a feed abundantly containing phosphorus or carbohydrates. SOLUTION: This transgenic plant comprises a genomic DNA containing a promoter and a gene containing a nucleotide sequence encoding a hydrolase and operably connected to the promoter. The promoter drives the expression of the hydrolase in seeds during development of the transgenic plant, seeds during germination, germinated seeds or plant seed tissues of young plants grown from the germinated seeds.

    Abstract: PROBLEM TO BE SOLVED: To obtain a transgenic animal model for providing better knowledge about a phenomenon of molecules for adjusting the differentiation of fat cells and the storage of fat at an organic level in order to more understand a mechanism for leading to obesity and develop a strategy for controlling a specific type of obesity. SOLUTION: This transgenic animal in which the genomic DNA comprises a gene containing a C/EBPα promoter operably linked to a DNA sequence encoding a C/EBPβ polypetide. In the transgenic animal, the genomic DNA is capable of exhibiting fat accumulation reduced in white fat tissues of the transgenic animal as compared with a control animal without containing the gene.
