Sulforaphane and its glutathione conjugate but not sulforaphane nitrile induce UDP-glucuronosyl transferase (UGT1A1) and glutathione transferase (GSTA1) in cultured cells. 2,a, [H3]thymidine incorporation into DNA was rapidly inhibited after sulforaphane treatment, decreasing to 63 4% of control levels within 60 min. 6D) when observed using phase-contrast microscopy. Thus, we utilize synthetic R,S-sulforaphane for all remaining experiments. Conclusion: Nutr. Zhang Y., Talalay P. Mechanism of differential potencies of isothiocyanates as inducers of anticarcinogenic phase 2 enzymes. Animal body weight in sulforaphane-treated group was 2 g less than controls at the end of 3 weeks (P = 0.02). By contrast,our results clearly show an increase in the bax protein content that appears after a 24-h period of treatment with 5 and 15 msulforaphane, suggesting that sulforaphane induces apoptosis in HT29 cells via a bax-dependent pathway. Both cell lines were inhibited from proliferation to the same extent when incubated with 10 mol/L sulforaphane. Cells treated at the higher sulforaphane dose (40 mol/L) showed a decrease in mitosis (E and F). Representative viable cells are identified in boxed region (A). 7D) of the mitotic cell cluster shows an accumulation of cells that are cyclin A negative and cyclin B1 positive, which is consistent with cells in metaphase (30). It has been shown that sulforaphane may protect against various types of cancer, may also decrease the risk of cardiovascular disease, and help in autism and osteoporosis. In recent years, there has been a shift in the cancer chemoprevention paradigm with a significant focus turning towards bioactive components of human diets for their anticancer properties. Before Briefly, Nrf2 is a transcription factor that is bound to the protein Kelch-like ECH-associated protein 1 (Keap1) in the cytosol ( Figure 3 ). Sulforaphane inhibits extracellular, intracellular, and antibiotic-resistant strains of. We thank Sue Chow and Kit Frances Tong for their flow cytometry technical assistance. 3 and 4, sulforaphane cytotoxicity is mediated in part by caspase-3 and caspase-8 and consequently may be reduced by incubating simultaneously with a general caspase inhibitor zVAD.fmk.

Almuhayawi MS, AbdElgawad H, Al Jaouni SK, Selim S, Hassan AHA, Khamis G. Food Chem. To distinguish between apoptotic and potential necrotic or lysed cells that may also expose PS according to the loss of membrane integrity, we have concomitantly used PI, a DNA dye that is excluded from cells with a nonleaky plasma membrane (i.e., normal or apoptotic). Sangkret S, Pongmalai P, Devahastin S, Chiewchan N. Sci Rep. 2019 Jul 8;9(1):9882. doi: 10.1038/s41598-019-46382-7. SFN inhibits mTOR in a concentration- and time-dependent manner, and this inhibition occurs in the presence or in the absence of NRF2. The classical DNA ladder assay shown by gel electrophoresis did not reveal an apoptotic pattern in HT29 cells treated with sulforaphane for up to 3 days (data not shown). SFN is derived from a. Ye L, Zhang Y. We observed that treatment of PANC-1 cells with sulforaphane induced loss of procaspase-8 and increase of the cleaved form, consistent with activated caspase-8 and the death receptor pathway (Fig. Similarly, the simultaneous incubation of sulforaphane with an antioxidant, N-acetyl-l-cysteine, also reduced cell damage (Fig. Unable to load your collection due to an error, Unable to load your delegates due to an error. UCN-01 abrogates G2 arrest by the inhibition of Chk1 phosphorylation, permitting the normal progression of cdc25 phosphatase to remove inhibitory phosphate groups from the mitosis-promoting kinase cdc2 (33, 34). Front Endocrinol (Lausanne). In contrast, the antiapoptotic bcl-2 protein was not detected in our cells. Canman C. E., Tang T. Y., Normolle D. P., Laurence T. S., Maybaum J. Interestingly, flow cytometry analysis also showed the presence of a sub-G1 peak characteristic of potential apoptotic cells(Fig. 9 also shows that as the level of bax increased, cytochrome c could be detected in the cytosol, whereas its level in the mitochondria decreased. doi: 10.1002/open.202200181. Effects of. It is produced when the enzyme myrosinase transforms glucoraphanin, a glucosinolate, into sulforaphane upon damage to the plant (such as from chewing or chopping during food preparation), which allows the two compounds to mix and react. To better determine which type of apoptotic pathway was induced by sulforaphane, extracts from HT29 cells at various times after sulforaphane treatment were examined by Western blotting using p53-,bax-, bcl-2-, PARP-, and cytochrome c-specific antibodies(Fig. 6,A) compared to control cells (Fig. This was evidenced by the presence of a proteolytic fragment of the caspase-3 substrate PARP in treated cells, suggesting that caspase-3 was activated, as has been recently shown in isothiocyanate-treated HeLa cells (30).

For the assay of cytochrome c, both cytosolic and mitochondrial fractions were prepared as described in Materials and Methods. Cytochrome c and actin levels in cytosol and mitochondria were determined using Western blots. Accumulation of cells at 4C DNA content was observed when cells were incubated with 10 mol/L sulforaphane. Evidence from epidemiological and experimental studies have emerged, enhancing the clinical plausibility and translational value of sulforaphane in cancer chemoprevention. Place jar in a dark, warm place (cupboards work great!) Sulforaphane increases tumor suppressor protein transcription and inhibits histone deacetylase activity. Morphological and ultrastructural changes of HT29 cells exposed to 15 m sulforaphane were examined at various times by electron microscopy (Fig. Sulforaphane (SFN) is a biologically active phytochemical found abundantly in broccoli. Sulforaphane and Other Isothiocyanates Induce Cell Death in Naive Leaf Tissue Leaf infiltration experiments were conducted in order to determine the concentration of sulforaphane needed to induce cell death. Although the presence of sulforaphane in the blood or intestine has not yet been quantified, consumption of 100 g of broccoli could release 40 mol of sulforaphane, suggesting that local concentrations in the low micromolar range may be achieved in vivo(39, 40, 41). Disclaimer, National Library of Medicine However, it decreased dramatically (down to 47%) after 3 h of treatment, indicating that a prolonged treatment affects all the major biosynthetic pathways (data not shown). Chiang W. C. K., Pusateri D. J., Leitz R. E. A. Ng SSW, Tsao MS, Chow S, Hedley DW. Xiao D, Singh SV. The greater sensitivity of PANC-1 cells to the lower doses of sulforaphane was associated with inability to increase GSH levels and might be due to deficient detoxification enzyme induction pathways as reported previously for MCF-7 and HT-29 cells (49). After 17 days of tumor establishment in severe combined immunodeficient mice, at the start of exponential tumor growth phase, animals were randomly divided into the treatment groups (n = 8). Results are the mean SE of three separate experiments. The edible plant belonging to the family of cruciferae such as broccoli is a rich source of glucoraphanin, a precursor of isothiocyanate sulforaphane which is considered to be a potent anti-cancer agent.

We never observed PI staining among the annexin V-positive cells (data not shown), excluding the presence of necrotic or lysed cells in the population. By immunoblotting, 24 hours post-treatment shows phospho-cdc2 (Tyr15) and total cdc2 (G). To investigate possible mechanisms by which sulforaphane would interfere with cell cycle progression, we evaluated the cellular content of G2-M-phase-related cyclins A and B1. However, the absence of DNA degradation in small fragments has also been reported in some cells undergoing apoptosis (19), and we cannot exclude the cleavage of DNA in a high molecular weight fragment undetectable by simple agarose gel electrophoresis. Sci. 5C and F). 10). More specifically, sulforaphane is part of a group of plant-based disease-fighting phytochemicals called isothiocyanates. Schematic presentation of anticancer mechanisms. 1 and 5). When HT29 cells were incubated for 48 h with increasing concentrations of sulforaphane, we observed a net decrease in the total number of cells and an accumulation of cells floating in the culture medium (Fig. Epub 2020 Dec 3. Moreover, about half of the floating cells recovered in the culture medium were subdiploid, with the other half being in the G2-M phase(data not shown), strengthening the relationship between G2-M-phase accumulation and apoptotic triggering. Before Such statistics warrant a collaborative engagement of conventional and complementary and alternative therapies to contain and manage cancer. Many classes of cancer chemopreventive agents, including naturally occurring and pharmaceutical compounds, are studied for efficacy in vivo and in vitro. 3). 2022 Jan 28;11(3):364. doi: 10.3390/plants11030364. Sulforaphane (SFN): An Isothiocyanate in a Cancer Chemoprevention Paradigm The International Agency for Research on Cancer (IARC) in its latest <i>World Cancer Report (2014)</i> has projected the increase in the global cancer burden from 14 million (2012) to 22 million incidence annually within the next two decades. In addition, SFN inhibited the activity of the cytoplasmic histone deacetylase 6 (HDAC6), the inhibition of which has been reported to promote the acetylation and decreases the kinase activity of AKT. Food. Mice were observed to decrease in activity level when a sulforaphane dose of 500 mol/kg body weight was given i.p., with death occurring in some animals when the dose was further increased. It is produced when the enzyme myrosinase transforms glucoraphanin, a prodrug or storage form of SFN, into SFN upon damage to the plant (such as . SFN is an isothiocyanate that occurs in a stored form as glucoraphanin in cruciferous vegetables (Vanduchova et al., 2018). Genome-Wide Association Reveals Trait Loci for Seed Glucosinolate Accumulation in Indian Mustard (, http://www.who.int/mediacentre/factsheets/fs297/en/index.html, NCI CPTC Antibody Characterization Program. Sylvia Walters never planned to be in the food-service business. Clipboard, Search History, and several other advanced features are temporarily unavailable. We then examined whether the expression of bax could promote the release of mitochondrial cytochrome c into the cytosol. Sulforaphane is an isothiocyanate occurring in stored form as glucoraphanin in cruciferous vegetables such as cabbage, cauliflower, and kale, and at high levels in broccoli especially in broccoli sprouts. Correlated dot plots of cellular content of reactive oxygen intermediate versus GSH in untreated, control cells compared with 10 mol/L sulforaphane-treated cells for 24 hours in MIA PaCa-2 (A and B) and PANC-1 (C and D), respectively.

Soni DV, Jacobberger JW. Careers. Glucoraphanin requires the plant enzyme myrosinase for converting it into sulforaphane. This is similar to the effects of nocodazole and may occur by the disruption of microtubules by sulforaphane (22, 42), whereupon it is expected that the activity of the mitotic spindle checkpoint is maintained and arrest cells in metaphase. However, while all cruciferous vegetables contain high amounts of sulforaphane , broccoli sprouts possess 20 times more sulforaphane concentration than the mature broccoli plant. The results from more than three independent experiments (Fig. However, the release of cytochrome c in the cytosol and the cleavage of PARP were also low at this concentration, suggesting a delay between the induction of bax and the final processes of apoptosis. Activated caspase-8 occurred prior to the activation of caspase-3 as observed by the loss of procaspase-3 (Fig. The resistance of cancer to therapy may be due in part to the high frequency of mutation in p53 that impairs p53-dependent apoptosis. Sulforaphane (SFN), a naturally-occurring isothiocyanate enriched in cabbage and broccoli, has been provided as food supplements to improve weight management and reduce lipid levels.
