Synthesis and anti-cancer activity of ND-646 and its derivatives as acetyl-CoA carboxylase 1 inhibitors.

Acetyl-coA carboxylase 1 (ACC1) is the first and rate-limiting enzyme in the de novo fatty acid synthesis (FASyn) pathway. In this study, through public database analysis and clinic sample test, we for the first time verified that ACC1 mRNA is overexpressed in non-small-cell lung cancer (NSCLC), which is accompanied by reduced DNA methylation at CpG island S shore of ACC1. Our study further demonstrated that higher ACC1 levels are associated with poor prognosis in NSCLC patients.

Retrospective analysis of 119 cases of pediatric acute promyelocytic leukemia: Comparisons of four treatment regimes.

Clinical trials have demonstrated that pediatric acute promyelocytic leukemia (APL) is highly curable. Small-scale studies have reported on the treatment of APL using one or two treatment regimes. Here, we report a multiple center-based study of 119 cases of pediatric APL treated with four regimes based on all-trans-retinoic acid (ATRA).

Signal pathways in ouabain-induced proliferation of leukemia cells.

Background: Cardiotonic steroids (CTSs) can bind to Na(+)/K(+)-ATPase and activate protein kinase cascades, resulting in changes in cell proliferation, differentiation or apoptosis in a cell-specific manner. We explored the participation of ouabain-activated signaling pathways in growth regulation of leukemia cells.

Methods: Lymphocytic leukemia Jhhan cells and megakaryocytic leukemia M07e cells were incubated at different concentrations of ouabain (0, 1 and 10 nmol) for 24 hours.
