Project description:To investigate the effect of apigenin on gene expression, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to suppress the cell proliferation of human acute myeloid leukemia (AML) cell lines. HL-60 amn NB4 cells were treated with apigenin for 24 h in vitro.

Project description:Age is the primary risk factor for many chronic diseases and cognitive decline during brain aging may increase dementia risk. Hallmarks of brain aging including neuronal dysfunction and glial contribute to reduced cognitive function, and there is a persistent lack of effective treatments. Bioactive plant compounds called “nutraceuticals” can target age-related cellular processes and may protect cognitive function. Apigenin is a flavone found in plants such as chamomile and can inhibit hallmarks of aging such as cellular senescence, mitochondrial dysfunction, and impaired proteostasis. However, the underlying mechanisms of apigenin in the brain are not fully understood. Here, we characterized brain transcriptome changes in young and old mice given apigenin in drinking water and examined potential mechanisms in human astrocytes. Consistent with previous studies, we observed improved novel object recognition in old mice treated with apigenin versus old controls. Transcriptome analyses in old controls found differentially expressed genes related to immune responses, inflammation, and cytokine regulation versus young. Fewer differences were observed in old apigenin-treated versus old controls, but these changes were related to development, behavior, and antiviral responses. The majority of upregulated genes in old mice were downregulated with apigenin treatment and associated with immune responses. Similarly, the genes that were reduced with aging, but increased in old apigenin-treated mice were related to pathways important for neurological function/disease, cellular maintenance, and homeostatic signaling. We also found that glial cells drove the majority of the transcriptome differences with aging and apigenin-treatment. To explore the mechanism of action for apigenin in glial cells, we treated replicatively aged astrocytes with apigenin and observed reduced markers of inflammation and cellular senescence. Collectively, our data support the role of apigenin as a protector of cognitive and neuronal function protectant through the suppression of neuroinflammatory genes and proteins and may be especially important in non-neuronal cells.

Project description:There is no known single therapeutic drug for treating hypercholesterolemia that comes with negligible systemic side effects. In the current study, using next generation RNA sequencing approach in mouse embryonic fibroblasts we discovered that two structurally related flavonoid compounds, Apigenin and Chrysin exhibited moderate blocking ability of multiple transcripts that regulate rate limiting enzymes in the cholesterol biosynthetic pathway. The observed decrease in cholesterol biosynthesis pathway correlated well with an increase in transcripts involved in generation and trafficking of ketone bodies as evident by the upregulation of Bdh1 and Slc16a6 transcripts. Impact statement - The hypocholesterolemic potential of Apigenin and Chrysin at higher concentrations along with their ability to generate ketogenic substrate especially during embryonic stage is useful or detrimental for embryonic health is not clear and still debatable. Our findings will set the stage for translating this information to whole animal and clinical studies that could shed light to the existing information regarding safe use of Apigenin and Chrysin, specifically to embryonic health.

Project description:Acute myeloid leukemia (AML) is a clonal hematopoietic malignancy, characterized by expansion of immature leukemic blasts in the bone marrow. In AML, specific tyrosine kinases have been implicated in leukemogenesis, and are associated with poor treatment outcome. However, targeted therapy using kinase inhibitors (KIs) has had limited success, and may be improved by proper patient selection. We performed phosphotyrosine (pY) based, label-free phosphoproteomics to identify hyperphosphorylated, active kinases in AML cell lines as targets and predictive biomarkers to select KIs for treatment. We identified 3605 class I phosphorylation sites in 16 AML cell lines (EOL-1, KG-1a, MM6, KG-1, ME-1, NB-4, Kasumi-3, MV4-11, THP-1, HEL, HL-60, Kasumi-1, Kasumi-6, ML-2, OCI-AML3, MOLM-13) that exhibited large variation in the number and level of phosphopeptides per cell line (241-2764). Ranking analyses successfully pinpointed the hyperactive kinases PDGFRA, FGFR1, KIT, and FLT3 in eight cell lines with a corresponding kinase mutation. Additionally, we identified unexpected drivers in two more cell lines (PDGFRA in Kasumi-3 and FLT3 in MM6) which proved sensitive to specific kinase inhibitors. Six cell lines without a clear receptor tyrosine kinase (RTK) driver showed evidence of MAPK1/3 activation, consistent with the presence of activating RAS mutations. Our data show the potential of pY phosphoproteomics to identify key drivers in AML cells, and the predictive value of the phosphoproteome profiles in TKi selection for targeted treatment.

Project description:Down syndrome (DS), a genetic condition leading to intellectual disability, is characterized by triplication of human chromosome 21. Neuropathological hallmarks of DS include abnormal central nervous system development that manifests during gestation and extends throughout life. As a result, newborns and adults with DS exhibit cognitive and motor deficits and fail to meet typical developmental and lack independent life skills. In the last two decades, a number of preclinical treatment studies showed beneficial effects in the Ts65Dn mouse model. As of summer 2020, 13 pharmacological interventions have been tested with little evidence of success in humans with DS. Potential reasons for this failure may be related to the fact that these therapeutic interventions were carried out too late, and not during the prenatal and early postnatal critical periods for brain development. To date, no prenatal treatment studies have been reported in pregnant women carrying fetuses with T21. A limited number of prenatal treatment studies using fluoxetine, maternal choline supplementation and the neuroprotective peptides NAP and SAL have been described using the Ts65Dn mouse model of DS. In our previous studies, we integrated gene expression data from nine different cellular and tissue sources in both humans with DS and mouse models to identify common dysregulated signaling pathways and cellular processes. We demonstrated that pathway abnormalities associated with DS were the result of gene-dosage specific effects and the consequence of a global stress response with activation of compensatory mechanisms. To counteract these genome-wide abnormalities, we used the Connectivity Map database (www.broadinstitute.org/CMap) to discover molecules that could be repurposed to rescue the transcriptome and promote more typical brain development in individuals with DS. One of the molecules that had the most consistent negative scores (hence, negating the dysregulated gene expression signatures in DS) across tissues and species was apigenin (4’, 5, 7-trihydroxyflavone). Here, we hypothesized that prenatal treatment with apigenin would partly rescue the global gene expression dysregulation to improve neurogenesis and postnatal cognitive outcomes in DS. In the current study, we used a human in vitro cell model (amniocytes derived from live fetuses with Trisomy 21 and euploid fetuses) and the Ts1Cje mouse model of DS to evaluate the effects of apigenin as a potential therpay for prenatal brain defects and postnatal cognitive outcome in DS. We demonstrated that apigenin is a safe treatment that can rescue oxidative stress and total antioxidant capacity imbalance in human amniocytes from fetuses with T21. It also improved several postnatal behavioral deficits in the Ts1Cje mouse model. We also showed that apigenin achieves its therapeutic action by triggering the expression of neurogenic genes, suppressing inflammation via inhibiting NFκB and by reducing the production of pro-inflammatory cytokines, while promoting the production of anti-inflammatory cytokines, angiogenic and neurotrophic factors.
