Pelargonium species have various uses in folk medicine as traditional remedies, and several of them have been screened for their biological activity, including anticancer. Pelargonium quercetorum Agnew (P. quercetorum) is traditionally used for its anthelminthic activity. However, little is known about its biological activity or its effect on cancer cells. The aim of the present study was to de...

Immunofluorescence studies revealed that adenovirus induces a reorganization of the cytokeratin system in lytically infected HeLa cells. At 24 h postinfection, the cytokeratin network began to disassemble into prominent spheroid globules. By 36 h postinfection, host cell lysis occurred, accompanied by the formation of perinuclear cytokeratin clumps and additional spheroid globules. Immunoblots ...

We present a new strategy for the differentiation of embryonic stem (ES) cells into insulin-producing cells via a multi-step process without selection and induction of nestin-positive cells. During ES cell differentiation, transcript levels of genes characteristic of early and mature beta cells including Pdx1, Pax4, insulin and islet amyloid pancreatic peptide are up regulated. Islet-like clust...

BACKGROUND Previously we found some low molecular weight proteins identified as histone in hepatocelluar carcinoma. Our objective was to clarify whether the coimmunoprecipitation of histone and cytokeratin 18 was an artifact or not. MATERIALS AND METHODS Histone 3 and cytokeratin 18 were investigated in three cases of human hepatocellular carcinoma and one case of normal liver tissue. Nuclei ...

The structural proteins cytokeratin 18 (CK18) and its coexpressed complementary partner CK8 are expressed in a variety of adult epithelial organs and may play a role in carcinogenesis. In this study, we focused on the biological functions of CK18, which is thought to modulate intracellular signaling and operates in conjunction with various related proteins. CK18 may affect carcinogenesis throug...
