Inhibitory activities of three annonaceous acetogenins on NADH oxidase of chicken liver mitochondria. (1/25)

Annonaceous acetogenins (ACG) are natural products found in the plant family Annonaceae and which strongly inhibited mitochondrial complex I. The inhibition of NADH oxidase of chicken liver mitochondria by three different structural ACG was studied here, and ACG was shown to have potent inhibitory activities similar to rotenone for NADH oxidase. The IC(50) values indicated that bis-adjacent tetrahydrofuran (THF) type squamocin C was more potent than non-adjacent bis-THF type squamostatin B, and the latter was more potent than non-THF type compound 1 in the assay. The roles of structural factors of ACG such as the terminal gamma-lactone, the features of other ring moieties and hydroxyl groups, as well as the alkyl chain were simply discussed in this study.  (+info)

Differential cytotoxic effects of Annona squamosa seed extracts on human tumour cell lines: role of reactive oxygen species and glutathione. (2/25)

Annonaceous acetogenins are a new class of compounds that have been reported to have potent pesticidal, parasiticidal, anti-microbial, cell growth inhibitory activities. In this study, organic and aqueous extracts from the defatted seeds of Annona squamosa (custard apple) were tested on different human tumour cell lines for antitumoural activity. While organic and aqueous extracts induced apoptosis in MCF-7 and K-562 cells, they failed to do so in COLO-205 cells. Treatment of MCF-7 and K-562 cells with organic and aqueous extracts resulted in nuclear condensation, DNA fragmentation, induction of reactive oxygen species (ROS) generation and reduced intracellular glutathione levels. In addition downregulation of Bcl-2 and PS externalization by Annexin-V staining suggested induction of apoptosis in MCF-7 and K-562 cells by both the extracts through oxidative stress. On the contrary, COLO-205 cells showed only PS externalization but no change in ROS and glutathione levels. These observations suggest that the induction of apoptosis by A. squamosa extracts can be selective for certain types of cancerous cells.  (+info)

REM sleep behavior disorder in patients with guadeloupean parkinsonism, a tauopathy. (3/25)

STUDY OBJECTIVE: To describe sleep characteristics and rapid eye movement (REM) sleep behavior disorder in patients with Guadeloupean atypical parkinsonism (Gd-PSP), a tauopathy resembling progressive supranuclear palsy that mainly affects the midbrain. It is possibly caused by the ingestion of sour sop (corossol), a tropical fruit containing acetogenins, which are mitochondrial poisons. DESIGN: Sleep interview, motor and cognitive tests, and overnight videopolysomnography. PATIENTS: Thirty-six age-, sex-, disease-duration- and disability-matched patients with Gd-PSP (n = 9), progressive supranuclear palsy (a tauopathy, n = 9), Parkinson disease (a synucleinopathy, n = 9) and controls (n = 9). SETTINGS: Tertiary-care academic hospital. RESULTS: REM sleep behavior disorder was found in 78% patients with Gd-PSP (43% of patients reported having this disorder several years before the onset of parkinsonism), 44% of patients with idiopathic Parkinson disease, 33% of patients with progressive supranuclear palsy, and no controls. The percentage of muscle activity during REM sleep was greater in patients with Gd-PSP than in controls (limb muscle activity, 8.3%+/-8.7% vs 0.1%+/- 0.2%; chin muscle activity, 24.3%+/- 23.7% vs 0.7%+/-2.0%) but similar to that of other patient groups. The latency and percentage of REM sleep were similar in patients with Gd-PSP, patients with Parkinson disease, and controls, whereas patients with progressive supranuclear palsy had delayed and shortened REM sleep. CONCLUSION: Although Gd-PSP is a tauopathy, most patients experience REM sleep behavior disorder. This suggests that the location of neuronal loss or dysfunction in the midbrain, rather than the protein comprising the histologic lesions (synuclein versus tau aggregation), is responsible for suppressing muscle atonia during REM sleep. Subjects with idiopathic REM sleep behavior disorder should avoid eating sour sop.  (+info)

Genotoxic and cytotoxic effects produced by acetogenins obtained from Annona cherimolia Mill. (8/25)

In the present study we extracted three isomeric acetogenins (Ace) from the seeds of Annona cherimolia Mill. (Annonaceae) and determined their genotoxic and cytotoxic potential in mice. Our results showed a significant increase in the rate of micronucleated polychromatic erythrocytes induced by Ace with respect to the value for the control group; the effect was less pronounced than that observed with daunorubicin (Dau). To evaluate cytotoxicity, we determined the proportion of polychromatic erythrocytes with respect to the number of normochromatic erythrocytes, and we found an inhibitory effect induced by Ace that was quite similar to that observed with Dau. Besides, by means of the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide test, we also determined the cytotoxicity of Ace in both a normal fibroblast mouse cell line and in a line derived from human colon cancer. In this assay, the strongest decrease in viability corresponded to the malignant cell line. Our results established for the first time the genotoxic capacity of these compounds in vivo, and confirmed their cytotoxic potential in cultured cells.  (+info)

Annona squamosa L., a popular fruit tree, is the most widely cultivated species of the genus Annona. The lack of transcriptomic and genomic information limits the scope of genome investigations in this important shrub. It bears aggregate fruits with numerous seeds. A few rare accessions with very few seeds have been reported for Annona. A massive pyrosequencing (Roche, 454 GS FLX+) of transcriptome from early stages of fruit development (0, 4, 8 and 12 days after pollination) was performed to produce expression datasets in two genotypes, Sitaphal and NMK-1, that show a contrast in the number of seeds set in fruits. The data reported here is the first source of genome-wide differential transcriptome sequence in two genotypes of A. squamosa, and identifies several candidate genes related to seed development. Approximately 1.9 million high-quality clean reads were obtained in the cDNA library from the developing fruits of both the genotypes, with an average length of about 568 bp.

Graviola is a substance that comes from a tree in the rain forests of Africa, South America, and Southeast Asia. Its scientific name is Annona muricata. It is also known as cherimoya, guanabana, soursop, custard apple, and brazilian paw paw. In many countries, people use the bark, leaves, root, and fruits of this tree for traditional remedies. The active ingredient is thought to be a type of plant compound (phytochemical) called annonaceous acetogenins.People in African and South American countries have used graviola to treat infections with viruses or parasites, rheumatism, arthritis, depression, and sickness. We know from research that some graviola extracts can help to treat these conditions. In laboratory studies, graviola extracts can kill some types of liver and breast cancer cells that are resistant to particular chemotherapy drugs. But there havent been any large scale studies in humans. So we dont know yet whether it can work as a cancer treatment or not. Overall, there is no evidence ...

Like most species of Annona, it requires a tropical or subtropical climate with summer temperatures from 25 °C (77 °F) to 41 °C (106 °F), and mean winter temperatures above 15 °C (59 °F). It is sensitive to cold and frost, being defoliated below 10 °C (50 °F) and killed by temperatures of a couple of degrees below freezing. It is only moderately drought-tolerant, requiring at least 700 mm of annual rainfall, and will not produce fruit well during droughts. It will grow from sea level to 2,000 metres (6,600 ft) and does well in hot dry climates, differing in its tolerance of lowland tropics from many of the other fruit bearers in the Annona family. It is quite a prolific bearer, and it will produce fruit in as little as two to three years. A five-year-old tree can produce as many as 50 sugar apples. Poor fruit production has been reported in Florida because there are few natural pollinators (honeybees have a difficult time penetrating the tightly closed female flowers); however, hand ...

Maintaining diverse germplasm available to plant breeders is important to the long-term genetic improvement of any crop. Although older selections were lost 70 to 80 years ago, the North American pawpaw is in a favorable position to have diverse and superior germplasm identified and maintained, because it is in the early stages of domestication and the wild population is thriving over an extensive territory. Eighteen polymorphic SSR loci, including 13 new loci, were used for fingerprinting and genetic analysis in pawpaw. These SSR loci were useful in examining whether genetically unique cultivars are being developed to enhance the genetic diversity of pawpaw cultivars. This is the first report of the influence of SSR motif on the marker polymorphism in pawpaw. The CA motif SSR loci appeared to have greater allele numbers and higher He and Ho than ATG and AAT loci motifs. The AT and GA repeats are the most common di-nucleotide repeats in plants (Bassil et al., 2005; Cardle et al., 2000; ...

Glioblastoma (GBM) is the most aggressive and lethal brain tumor in adults. Its invasive nature currently represents the most challenging hurdle to surgical resection. The mechanism adopted by GBM cells to carry out their invasive strategy is an intricate program that recalls what takes place in embryonic cells during development and in carcinoma cells during metastasis formation, the so-called epithelial-to-mesenchymal transition. GBM cells undergo a series of molecular and conformational changes shifting the tumor toward mesenchymal traits, including extracellular matrix remodeling, cytoskeletal re-patterning, and stem-like trait acquisition. A deeper understanding of the mechanisms driving the whole infiltrative process represents the first step toward successful treatment of this pathology.

This dataset contains the 5 TRFLP fragment data.. T4-like myovirus communities were analyzed by terminal restriction fragment length polymorphism (TRFLP) of g23, which encodes the major capsid protein (Chow and Fuhrman, 2012). Viral fingerprints were obtained from both terminal fragments (5 and 3). g23-TRFLP products were run in duplicate on non-adjacent lanes on an ABI377 by slab gel electrophoresis with internal size standards (Bioventures, Murfreesboro, TN, USA) every 25 bp (50-900 bp) or 50 bp (900-1400 bp). Peaks were identified in DAx (van Mierlo, Inc, Eindhoven, The Netherlands). Fragments (50-500 bp) were rounded to the nearest 0.1 bp and dynamically binned (Ruan, et al., 2006b; Chow and Fuhrman, 2012). The resulting bins were manually curated to merge bins ,0.1 bp wide with the nearest neighbor. Terminal fragments from in silico analysis of publicly available T4-like viral genomes were used to assign identities to environmental g23-TRFLP OTUs. Unique fragment lengths were considered ...

whether you choose chemotherapy or alternatives. Our research at Cancer Defeated has come across a plant that takes on cancer cells in a different way than other natural cancer fighters. Its believed to be the single most effective treatment to kill the hard-to-get-rid-of, multiple-drug-resistant (MDR) cancer cells.. Its also reportedly been successful in shrinking tumours naturally and preventing the growth of new cancer cells with minimal side effects. When this plant is used in conjunction with chemotherapy, the chemo turns out to be much more effective at tackling MDR cells.. The magic plant is the pawpaw tree. Not only can it improve the effectiveness of chemo, it also has power on its own. If you avoid chemo and just take pawpaw, you may have luck shrinking a tumour on your own, although I dont recommend relying on one therapy.. Zap cells at the energy source. The pawpaw tree boasts the largest edible fruit native to North America. Its often confused with papaya, a tropical fruit that ...

The pawpaw is the largest edible fruit that is native to the United States. Pawpaws are indigenous to 26 states in the U.S., in a range extending from northern Florida to southern Ontario and as far west as eastern Nebraska. They have provided delicious and nutritious food for Native Americans, European explorers and settlers, and wild animals. They are still being enjoyed in modern America, chiefly in rural areas. There are 27 varieties (Table 1) currently available from more than 50 commercial nurseries in the U.S. Most enthusiasts agree that the best way to enjoy pawpaws is to eat them raw, outdoors, picked from the tree when they are perfectly ripe. But there are also numerous ways to use them in the kitchen and extend the enjoyment of their tropical flavor beyond the end of the harvest season. The unique flavor of the fruit resembles a blend of various tropical flavors, including banana, pineapple, and mango. The flavor and custard-like texture make pawpaws a good substitute for bananas in ...
