Brassica vegetables are widely consumed all over the world, especially in North America, Asia, and Europe. They are a rich source of sulfur compounds, such as glucosinolates (GLSs) and isothiocyanates (ITCs), which provide health benefits but are also suspected of having a goitrogenic effect. Adhering to PRISMA guidelines, we conducted a systematic review to assess the impact of dietary interventions on thyroid function, in terms of the potential risk for people with thyroid dysfunctions. We analyzed the results of 123 articles of in vitro, animal, and human studies, describing the impact of brassica plants and extracts on thyroid mass and histology, blood levels of TSH, T3, T4, iodine uptake, and the effect on thyroid cancer cells. We also presented the mechanisms of the goitrogenic potential of GLSs and ITCs, the limitations of the studies included, as well as further research directions. The vast majority of the results cast doubt on previous assumptions claiming that brassica plants have antithyroid effects in humans. Instead, they indicate that including brassica vegetables in the daily diet, particularly when accompanied by adequate iodine intake, poses no adverse effects on thyroid function.

The Fabaceae family is known for the presence of isoflavones—phytoestrogens with potential chemopreventive effects against hormone-dependent cancers. This study aimed to optimize isoflavones extraction using a fractional factorial design and to quantitatively and qualitatively analyze 32 Fabaceae species native to Polish flora by HPLC-UV-VIS to indicate new, rich plant sources of isoflavones. The optimal extraction method was a 60 min reflux with 50% methanol and a plant material-to-solvent ratio of 1:125. The highest isoflavone levels were found in Trifolium medium (26.70 mg/g d.m.), Genista tinctoria (19.65 mg/g d.m.), and Trifolium pratense (12.56 mg/g d.m.). The obtained extracts were further evaluated for cytotoxic and antiproliferative activity against MCF7 and MDA-MB-231 human breast cancer cells. Genista tinctoria showed the highest cytotoxicity against MCF7, while Cytisus scoparius and Ononis arvensis were most effective against MDA-MB-231 at a dose of 500 µg/mL. The extracts were also characterized by varied, potent antioxidant properties, important in chemoprevention. A strong correlation was observed between isoflavone content and cytotoxic and antiproliferative activity exclusively in the estrogen receptor-positive MCF7 cell line. Importantly, the tested extracts demonstrated no toxic effects on normal human liver (HepG2), thyroid (Nthy-ori 3-1), or breast (MCF10A) cells, indicating a favorable safety profile.

Plants from the Fabaceae family are widely distributed around the world, especially in Europe, Asia and North America. They are a rich source of isoflavones, compounds with estrogen-like activity, which are suspected of having a chemopreventive effect against hormone-dependent cancers. Following the PRISMA guidelines, we conducted a systematic review aimed at assessing the impact of Fabaceae plant extracts on hormone-dependent cancer cells and the content of active compounds in plant raw materials. We analyzed the results of 63 articles from in vitro and in vivo studies describing the effect of plant extracts containing isoflavones on cancer cells, along with their anti-inflammatory and antioxidant potential. In the process, we determined the research limitations and future research directions. The collected results indicate the plant species with potentially high contents of phytoestrogens and anti-inflammatory, antioxidant and cytotoxic properties. They point to the potential use of plants in the diet as a source of compounds offering cancer prevention.

Brain tumors, including gliomas and neuroblastoma (NB), remain among the most aggressive and therapeutically challenging malignancies of the nervous system. Despite multimodal treatment, prognosis for high-grade gliomas and high-risk NB remains poor, largely due to pharmacological barriers and intrinsic therapy resistance. Isoflavones are plant-derived phytoestrogens that have attracted increasing attention because of their pleiotropic anticancer, anti-inflammatory, and neuroprotective properties. In this review, we focus on the molecular and cellular mechanisms that determine the biological activity of isoflavones in brain tumors, including estrogen receptor-dependent signaling, modulation of oncogenic pathways, and limitations related to blood-brain barrier permeability. We discuss how modulation of phosphoinositide 3-kinase (PI3K), mitogen-activated protein kinase (MAPK), AMP-activated protein kinase (AMPK), and nuclear factor kappa B (NF-κB) pathways contributes to antiproliferative and pro-apoptotic effects, and how limited brain bioavailability represents a major barrier to effective application. We identify key limitations of the current literature, including inconsistent epidemiological findings, poor standardization of experimental models, and limited pharmacokinetic characterization. Available data suggest that isoflavones represent promising adjuncts in brain tumor therapy, but their clinical relevance will depend on improving brain delivery and defining receptor-selective mechanisms of action.

Dietary factors, including the consumption of isoflavones-rich foods of plant origin, may contribute to the reduced incidence of prostate cancer. Isoflavones, natural phytoestrogens often found in legumes, can modulate estrogen and androgen receptor signaling. This study aimed to evaluate the biological potential of isoflavone-rich extracts obtained from twelve species from the Fabaceae family, targeting prostate cancer cell viability, proliferation, inflammatory markers, prostate-specific antigen secretion, and 5α-reductase activity. The tested extracts showed moderate cytotoxic activity against prostate cancer cell lines, apart from highly susceptible PC3 cells, and only weak toxicity to normal prostate epithelial cells. Significant antiproliferative activity was observed, especially for Cytisus scoparius, Ononis arvensis, and Genista tinctoria, while most extracts reduced prostate-specific antigen (PSA) secretion in normal prostate cells. Furthermore, the extracts showed anti-inflammatory properties by reducing the pro-inflammatory cytokine interleukin 6 (IL-6) and improving cytokine balance indices. Multivariate analyses revealed correlations between total isoflavone content and antiproliferative activity.

Skin aging, pigmentation disorders and skin barrier dysfunction are strongly associated with oxidative stress, chronic inflammation and extracellular matrix degradation. In this context, plant sprouts have gained popularity as a rich source of bioactive compounds and are becoming promising candidates for dermatological applications. The aim of this review was to summarize current scientific research on the potential of sprout extracts in skin care and to identify the biological mechanisms underlying their dermatological activity. A comprehensive literature search was conducted in Medline, Scopus, and Google Scholar databases up to February 2026. Studies assessing the effects of topical sprout extracts on skin structure, inflammation, pigmentation, and hair growth were included. A total of 31 studies met the inclusion criteria and were subjected to qualitative analysis. Available evidence indicates that sprout extracts have multifaceted effects relevant to skin health, including stimulation of collagen synthesis, inhibition of matrix metalloproteinases, improvement of epidermal hydration, melanogenesis, and suppression of inflammatory signaling pathways. These effects are largely attributed to bioactive compounds such as phenolic acids, flavonoids, isothiocyanates, and other antioxidant phytochemicals, which exhibit antioxidant, anti-inflammatory, and anti-aging properties. Preliminary clinical studies suggest that ingredients derived from sprouts may improve skin elasticity, hydration, and photoprotection. Although most of the evidence comes from in vitro and animal studies, it preliminarily supports the emerging concept of “food for skin” and highlights the potential of sprouted plant materials as multifunctional ingredients in dermatology.
