Extracts from sweet sorghum (Sorghum bicolor), a feedstock for biorefining, suppressed proliferation and elevated apoptosis in human colon cancer stem cells via suppression of Wnt/beta-catenin signaling pathway

Project description:In colorectal cancer, p53 is commonly inactivated, associated with chemo-resistance, and marks the transition from non-invasive to invasive disease. Cancers, including colorectal cancer, are thought to be diseases of aberrant stem cell populations, as stem cells are able to self-renew, making them long-lived enough to acquire mutations necessary to manifest the disease. We have shown that extracts from sweet sorghum stalk components eliminate colon cancer stem cells (CCSC) in a partial p53-dependent fashion. However, the underlying mechanisms are unknown. In the present study, CCSC were transfected with short hairpin-RNA against p53 (CCSC p53 shRNA) and treated with sweet sorghum phenolics extracted from different plant components (dermal layer, leaf, seed head and whole plant). While all components demonstrated anti-proliferative and pro-apoptotic effects in CCSC, phenolics extracted from the dermal layer and seed head were more potent in eliminating CCSC by elevating caspases 3/7 activity, PARP cleavage, and DNA fragmentation in a p53-dependent and p53-independent fashion, respectively. Further investigations revealed that the anti-proliferative and pro-apoptotic effects were associated with decreases in beta-catenin protein levels, and beta-catenin targets cyclin D1, cMyc, and survivin. These results suggest that the anti-proliferative and pro-apoptotic effects of sweet sorghum extracts against human colon cancer stem cells are via suppression of Wnt/beta-catenin pro-survival signaling in a p53-dependent (dermal layer) and partial p53-independent (seed head) fashion.

12hr 5-FU treatment vs. DMSO in SJSA cells (from 'A kinase independent role for CDK19 in p53 response')

Project description:The human Mediator complex regulates RNA Polymerase II transcription genomewide. A general factor that regulates Mediator function is the four-subunit Mediator kinase module, which contains either CDK8 or CDK19. Whereas CDK8 has been linked to specific signaling cascades and oncogenesis, the cellular roles of its paralog, CDK19, are poorly studied. To define cellular roles for CDK19, we used osteosarcoma cells (SJSA) that naturally lack endogenous CDK8 protein. Although stable CDK19 knockdown was tolerated in SJSA cells, it caused reduced proliferation vs. control shRNA cells. Global gene expression analyses (RNA-Seq) suggested that defects in cholesterol biosynthesis contributed to reduced proliferation in CDK19 knockdown cells (vs. shCTRL). Notably, proliferation defects were rescued with transient expression of wild-type or kinase-dead CDK19. Using RNA-Seq and other assays, we established a general role for CDK19 in the transcriptional response to 5-fluorouracil (5-FU), an inducer of genotoxic and metabolic stress. These experiments also implicated CDK19 in activation of p53 target genes during 5-FU treatment. To further probe a potential role for CDK19 in the p53 response, SJSA cells (shCDK19 vs. shCTRL) were treated with the p53 activator Nutlin-3. Remarkably, CDK19 was required for SJSA cells to return to a proliferative state following Nutlin-3 treatment, and this effect was kinase-independent. These results implicate CDK19 as a regulator of p53 stress responses and suggest a manifestation of CDK19 knockdown—potentially reduced levels of cholesterol metabolites—blocks cellular resistance to Nutlin-3.
