The authors of the above article misjudged the structure determination of MCF (metacytofilin). Our recent analyses using X-ray crystallography and NMR techniques revealed the correct structure as shown in Figs. 1, 2 and 3. The structure of MCF was id

The anti-diabetic effect of cytogenin was examined using streptozotocin-induced diabetes in mice. Cytogenin suppressed not only the increase of plasma glucose level but also the body weight reduction in diabetic mice. Histological examination of the

To find novel pharmacological tools useful for analyzing the molecular mechanism of apoptosis from natural resources, in the present study, we examined the activity of IC101, a cyclic depsipeptide isolated from Streptomyces sp. MJ202-72F3, to induce

Androgen receptor (AR) is a ligand-activated transcription factor that requires androgen binding to initiate a series of molecular events leading to specific gene activation. AR has been suggested to form an antiparallel homodimer based on the charac

Nephrotoxicity is known to be a major clinical side effect of aminoglycoside antibiotics. Aminoglycosides cause damage to proximal tubular cells in kidney, however the mechanism of toxicity is still unclear. In order to elucidate the mechanism of nep

Imbalances in the epithelial–stromal interactions are important in the pathogenesis of prostate cancer. However, we know little about androgenic regulation in the stroma of prostate cancer. We examined the cancer–stromal interaction paying attent

Selective augmentation of natural killer (NK) cells can suppress tumor metastasis, but molecular targets for NK cell activation have not been identified. We report here that cytostatin (CTS), a novel specific inhibitor of protein phosphatase (PP) 2A,

ICM0201 (1), a new inhibitor of murine osteoclastogenesis in culture was isolated from a fermentation broth of Cunninghamella sp. F-1490. The structure of ICM0201 was determined to be (3S, 10aR)-3, 4a-dihydroxy-2, 3, 4, 4a-tetrahydro-2H-pyrano[3, 2-b
