Relaxin (Rln), a polypeptide hormone of the insulin superfamily, is an ovarian peptide hormone that is involved in a diverse range of physiological and pathological reactions. In this study, we investigated the effect of Rln on bone morphogenetic protein 2 (BMP-2)-induced osteoblast differentiation and bone formation. Expression of Rln receptors was(More)
The inactivation of the p16INK4A (p16) gene by promoter hypermethylation has been reported in many human cancers. We previously reported that aberrant p16 RNA transcripts are expressed in hepatocellular carcinoma (HCC) cell lines having hypermethylated p16 promoters. In this study, we investigated the functional roles of aberrant p16 RNA transcripts in HCC(More)
Human gastric cancer SNU 484 cells express mutant p16, which migrates slower than the wild-type p16. We constructed an expression vector containing human p16 cDNA to evaluate the cytotoxic effects of exogenous p16 expression on SNU 484 cell proliferation and to explore the potential use of p16 in cancer gene therapy. The stable transfectant expressing(More)
The key pathogenesis of leukemia is the defection of the differentiation processes of hematopoietic stem cells. There are five APRO (anti-proliferative) genes, BTG1, BTG2, BTG3, TOB and TOB2, and it was reported that certain APRO genes are associated with cell differentiation. However, it is still unknown whether APRO genes are related with the(More)
Octalactin A and B (code names K1 and K2) are eight-membered-ring lactones from a marine bacterium. K1 is reportedly cytotoxic. Since access to this natural product is severely limited, the entire synthesis of K1 has been achieved in K. Buszek's laboratory, and several of its structural and stereochemical analogs (code names K3-K9) have been tested for(More)
