Medicinal Food Homology in Action: Flos Sophorae Immaturus-Broccoli Seed Extract Suppresses Tumor Growth through G2/M Arrest and EMT Inhibition

ABSTRACT: Despite advancements in cancer therapy, metastasis and chemoresistance remain critical challenges due to tumor heterogeneity and compensatory pathways. This study investigates the synergistic anti-tumor potential of Flos Sophorae Immaturus (FSI) and broccoli seed extract (BSE), two natural products aligned with the "medicinal food homology" paradigm. Using in vitro and in vivo models of lung and prostate cancers, we demonstrate that FSI-BSE (F/B extract) co-treatment exerts supra-additive effects by concurrently inducing G2/M cell cycle arrest and suppressing epithelial-mesenchymal transition (EMT). Mechanistically, with integrative LC-MS/MS, network pharmacology, molecular docking, transcriptomic profiling, and molecular experimental validation, this study revealed that F/B extract targets and disrupts the cell cycle regulators such as cyclin-dependent kinases (CDKs) and cell division cycle 25 (CDC25), as well as the EMT effectors (e.g., Matrix metalloproteinase, Snail, and E-cadherin). Additionally, F/B extract suppressed tumor growth without toxicity in xenograft mouse models, supported by unaltered organ histology and blood parameters. These findings demonstrate a polypharmacological strategy leveraging dietary botanicals to address cancer complexity. By bridging cell cycle arrest and EMT inhibition, F/B extract treatment offers a non-toxic adjuvant approach with translational potential, underscoring the therapeutic value of medicinal food homology in oncology.

Anti-cancer activity of Cotyledon orbiculata extract

Project description:We investigated the effects of the crude extract of a South African medicinal plant, Cotyledon orbiculata, on cell survival of colon (HCT116) cancer cell lines. Using RNASeq, we discovered that the extract interfered with mRNA regulatory pathways. Here, we found that the extract of Cotyledon orbiculata, a South African medicinal plant, had an anti-proliferative effect in cancer cells, mediated by apoptosis induced by alternative splicing of hnRNPA2B1 and BCL2L1.

Tubular Foxp2 promotes kidney fibrosis by regulating epithelial-mesenchymal transition and cell cycle arrest

Project description:Kidney fibrosis results in progressive loss of function, ultimately leading to kidney failure, for which there are limited effective therapeutic strategies. The transcription factor, Forkhead box P2 (Foxp2), has been implicated in organ development and tumorigenesis through its association with the epithelial-to-mesenchymal transition (EMT) process. In this study, we uncovered a novel role of Foxp2 in kidney fibrosis. Expression of Foxp2 was upregulated in kidney tubules from both human chronic glomerulonephritides and animal models of chronic kidney disease. In vitro, Foxp2 was induced in tubular epithelial cells via TGF-β/Smad3 signaling while knockdown of Foxp2 suppressed TGF-β-induced EMT and accumulation of extracellular matrix proteins. In vivo, tubule-specific deletion of Foxp2 attenuated kidney inflammation and tubulointerstitial fibrosis in murine unilateral ureteral obstruction and unilateral ischemic-reperfusion models of progressive CKD, which were accompanied by reduction in cell cycle arrest. Mechanistically, overexpression of Foxp2 inhibited tubular cell proliferation with induction of G2/M cell cycle arrest. Using chromatin-immunoprecipitation sequencing, we identified Foxp2 target genes that are enriched in PI3K/Akt and TGF-β signaling pathways, and further revealed that Foxp2 directly regulated the transcriptional activities of collagen-1, E-cadherin and p21 that are involved in EMT and cell cycle arrest, thereby promoting the profibrotic process. Collectively, our findings provide novel evidence that Foxp2 regulates TGF-β-induced EMT and cell cycle arrest, the key signaling pathways of kidney fibrosis, and suggest that Foxp2 may be a potential therapeutic target for kidney fibrosis.

Testing biological actions of medicinal plants from Northern Vietnam on zebrafish embryos and larvae: developmental, behavioral, and putative therapeutical effects.

Project description:Evaluating the risks and benefits of using traditional medicinal plants is of utmost importance for a huge fraction of the human population, in particular in Northern Vietnam. Zebrafish are increasingly used as a simple vertebrate model for testing toxic and physiological effects of compounds, especially on development. Here, we tested 12 ethanolic extracts from popular medicinal plants collected in Northern Vietnam for their effects on zebrafish survival and development during the first 4 days after fertilization. We characterized more in detail their effects on epiboly, hatching, growth, necrosis, body curvature, angiogenesis, skeletal development and mostly increased movement behavior. Finally, we confirm the effect on epiboly caused by the Mahonia bealei extract by staining the actin filaments and show that this extract also inhibits cell migration of mouse embryo fibroblasts. In conclusion, we show that zebrafish early life stages reveal that traditional medicinal plant extracts are able to affect embryo development to various degrees, prompting caution to apply these medications to pregnant women. In addition, we show that an extract causing delay in epiboly also inhibits mammalian cell migration, suggesting that this effect may serve as a preliminary test for identifying extracts that inhibit cancer metastasis.

State- and stimulus-specific dynamics of SMAD signaling determine fate decisions in individual cells

Project description:SMAD-mediated signaling regulates a broad range of cell fate decisions including apoptosis, cell cycle arrest and EMT. To elucidate how this relatively simple pathway realizes this complexity, we systematically investigate how SMAD-mediated responses are modulated by various ligands of the TGFβ family, and compare these ligand responses in quiescent and proliferating MCF10A cells.

Transcription of bovine milk and meat factors (BMMFs) in HEK293TT cells

Project description:We analyze the transcription of these bovine milk and meat factors (BMMFs) and MS isolates in human HEK293TT cells. While all analyzed DNA agents are readily transcribed, one of the MS brain isolates (MSBI1.176), sharing homology with a transmissible spongiform encephalopathy (TSE)-associated DNA molecule, is transcribed at highest levels. Our results support the transcription of an open reading frame (ORF) encoding a replication-associated protein, which is highly conserved among all isolated BMMFs. In the case of the cow milk isolate CMI1.252, transcription also occurs in a second large ORF. Transcriptome profiling upon BMMF expression identified host cellular gene expression changes related to cell cycle progression and cell viability control, indicating potential pathways for a pathogenic involvement of BMMFs.
