All-trans retinoic acid (ATRA) induces complete remission in almost all patients with acute promyelocytic leukemia (APL) via its ability to induce the in vivo differentiation of APL blasts. However, prolonged ATRA treatment can result in drug resistance. In previous studies, we generated a multi-drug-resistant HL60/ATRA cell line and found it to contain a new drug resistance-related gene segment, HA117. In this study, we demonstrate that ATRA induces multi-drug-resistant subpopulations of HL60 cells with a putative stem-like signature by up-regulating the expression of the new gene segment HA117...

The ginseng family, including Panax ginseng (Asian ginseng), Panax quinquefolius (American ginseng), and Panax notoginseng (notoginseng), is commonly used herbal medicine. White ginseng is prepared by air-drying after harvest, while red ginseng is prepared by a steaming or heating process. The anticancer activity of red ginseng is significantly increased, due to the production of active anticancer ginsenosides during the steaming treatment, compared with that of white ginseng. Thus far, anticancer studies have been mostly focused on Asian ginseng...

In the present work we have devised the synthesis of a novel promising carbon nanotube carrier for the targeted delivery of radioactivity, through a combination of endohedral and exohedral functionalization. Steam-purified single-walled carbon nanotubes (SWCNTs) have been initially filled with radioactive analogues (i.e. metal halides) and sealed by high temperature treatment, affording closed-ended CNTs with the filling material confined in the inner cavity. The external functionalization of these filled CNTs was then achieved by nitrene cycloaddition and followed by the derivatization with a monoclonal antibody (Cetuximab) targeting the epidermal growth factor receptor (EGFR), overexpressed by several cancer cells...
