Procyanidin oligomers selectively and intensively promote proliferation of mouse hair epithelial cells in vitro and activate hair follicle growth in vivo. (1/171)

We have previously reported that proanthocyanidins extracted from grape seeds possess growth-promoting activity toward murine hair epithelial cells in vitro and stimulate anagen induction in hair cycle progression in vivo. This report constitutes a comparison of the growth-promoting activity of procyanidin oligomers and the target cells of procyanidins in the skin. Results show that procyanidin dimer and trimer exhibit higher growth-promoting activity than the monomer. The maximum growth-promoting activity for hair epithelial cells with procyanidin B-2, an epicatechin dimer, reached about 300% (30 microM) relative to controls (= 100%) in a 5 d culture. Optimum concentration of procyanidin C-1, an epicatechin trimer, was lower than that of procyanidin B-2; the maximum growth-promoting activity of procyanidin C-1 was about 220% (3 microM). No other flavonoid compounds examined exhibit higher proliferative activities than the procyanidins. In skin constituent cells, only epithelial cells such as hair keratinocytes or epidermal keratinocytes respond to procyanidin oligomers. Topical application of 1% procyanidin oligomers on shaven C3H mice in the telogen phase led to significant hair regeneration [procyanidin B-2, 69.6% +/- 21.8% (mean +/- SD); procyanidin B-3, 80.9% +/- 13.0%; procyanidin C-1, 78.3% +/- 7.6%] on the basis of the shaven area; application of vehicle only led to regeneration of 41.7% (SD = 16.3%). In this paper, we demonstrate the hair-growing activity of procyanidin oligomers both in vitro and in vivo, and their potential for use as agents to induce hair growth.  (+info)

Suppression of extracellular signals and cell proliferation by the black tea polyphenol, theaflavin-3,3'-digallate. (2/171)

Previous studies in our laboratory have shown that the major green tea polyphenol, (-)-epigallocatechin-3-gallate (EGCG), suppressed autophosphorylation of epidermal growth factor (EGF) receptor induced by EGF in human A431 epidermoid carcinoma cells. In this study, we examined the inhibitory effects of black tea polyphenols, including theaflavin (TF-1), a mixture (TF-2) of theaflavin-3-gallate (TF-2a) and theaflavin-3'-gallate (TF-2b), theaflavin-3,3'-digallate (TF-3) and the thearubigin fraction on the autophosphorylation of the EGF and PDGF receptors in A431 cells and mouse NIH3T3 fibroblast cells, respectively. First, we examined the effects of these polyphenols on the proliferation of A431 and NIH3T3 cells. Both EGCG and TF-3 strongly inhibited the proliferation of A431 and NIH3T3 cells more than the other theaflavins did. In cultured cells with pre-treatment of tea polyphenol, TF-3 was stronger than EGCG on the reduction of EGF receptor and PDGF receptor autophosphorylation induced by EGF and PDGF, respectively. Other theaflavins slightly reduced the autophosphorylation of the EGF and PDGF receptors; furthermore, TF-3 could reduce autophosphorylation of the EGF receptor (or PDGF receptor) even with co-treatment with EGF (or PDGF) and TF-3, but EGCG was inactive under these conditions. In addition, TF-3 was stronger than EGCG in blocking EGF binding to its receptor. These results suggest that not only the green tea polyphenol, EGCG, but also the black tea polyphenol, TF-3, have an antiproliferative activity on tumor cells, and the molecular mechanisms of antiproliferation may block the growth factor binding to its receptor and thus suppress mitogenic signal transduction.  (+info)

Anti-tumor-promoting activity of a polyphenolic fraction isolated from grape seeds in the mouse skin two-stage initiation-promotion protocol and identification of procyanidin B5-3'-gallate as the most effective antioxidant constituent. (3/171)

Procyanidins present in grape seeds are known to exert anti-inflammatory, anti-arthritic and anti-allergic activities, prevent skin aging, scavenge oxygen free radicals and inhibit UV radiation-induced peroxidation activity. Since most of these events are associated with the tumor promotion stage of carcinogenesis, these studies suggest that grape seed polyphenols and the procyanidins present therein could be anticarcinogenic and/or anti-tumor-promoting agents. Therefore, we assessed the anti-tumor-promoting effect of a polyphenolic fraction isolated from grape seeds (GSP) employing the 7,12-dimethylbenz[a]anthracene (DMBA)-initiated and 12-O-tetradecanoylphorbol 13-acetate (TPA)-promoted SENCAR mouse skin two-stage carcinogenesis protocol as a model system. Following tumor initiation with DMBA, topical application of GSP at doses of 0.5 and 1.5 mg/mouse/application to the dorsal initiated mouse skin resulted in a highly significant inhibition of TPA tumor promotion. The observed anti-tumor-promoting effects of GSP were dose dependent and were evident in terms of a reduction in tumor incidence (35 and 60% inhibition), tumor multiplicity (61 and 83% inhibition) and tumor volume (67 and 87% inhibition) at both 0.5 and 1.5 mg GSP, respectively. Based on these results, we directed our efforts to separate and identify the individual polyphenols present in GSP and assess their antioxidant activity in terms of inhibition of epidermal lipid peroxidation. Employing HPLC followed by comparison with authentic standards for retention times in HPLC profiles, physiochemical properties and spectral analysis, nine individual polyphenols were identified as catechin, epicatechin, procyanidins B1-B5 and C1 and procyanidin B5-3'-gallate. Five of these individual polyphenols with evident structural differences, namely catechin, procyanidin B2, procyanidin B5, procyanidin C1 and procyanidin B5-3'-gallate, were assessed for antioxidant activity. All of them significantly inhibited epidermal lipid peroxidation, albeit to different levels. A structure-activity relationship study showed that with an increase in the degree of polymerization in polyphenol structure, the inhibitory potential towards lipid peroxidation increased. In addition, the position of linkage between inter-flavan units also influences lipid peroxidation activity; procyanidin isomers with a 4-6 linkage showed stronger inhibitory activity than isomers with a 4-8 linkage. A sharp increase in the inhibition of epidermal lipid peroxidation was also evident when a gallate group was linked at the 3'-hydroxy position of a procyanidin dimer. Procyanidin B5-3'-gallate showed the most potent antioxidant activity with an IC(50) of 20 microM in an epidermal lipid peroxidation assay. Taken together, for the first time these results show that grape seed polyphenols possess high anti-tumor-promoting activity due to the strong antioxidant effect of procyanidins present therein. In summary, grape seed polyphenols in general, and procyanidin B5-3'-gallate in particular, should be studied in more detail to be developed as cancer chemopreventive and/or anticarcinogenic agents.  (+info)

Inhibition of activator protein 1 activity and cell growth by purified green tea and black tea polyphenols in H-ras-transformed cells: structure-activity relationship and mechanisms involved. (4/171)

ras gene mutation, which perpetually turns on the growth signal transduction pathway, occurs frequently in many cancer types. The mouse epidermal JB6 cell line has been transfected with a mutant H-ras gene to mimic carcinogenesis in vitro. These transformed cells (30.7b Ras 12) are able to grow in soft agar, exhibiting anchorage independence and high endogenous activator protein 1 (AP-1) activity, which can be detected by a stable AP-1 luciferase reporter. The present study investigated the ability of different pure green and black tea polyphenols to inhibit this ras signaling pathway. The major green tea polyphenols (catechins), (-)-epigallocatechin-3-gallate (EGCG), (-)-epigallocatechin, (-)-epicatechin-3-gallate, (-)-epicatechin, and their epimers, and black tea polyphenols, theaflavin, theaflavin-3-gallate, theaflavin-3'-gallate, and theaflavin-3,3'-digallate (TFdiG), were compared with respect to their ability to inhibit the growth of 30.7b Ras 12 cells and AP-1 activity. All of the tea polyphenols except (-)-epicatechin showed strong inhibition of cell growth and AP-1 activity. Among the catechins, both the galloyl structure on the B ring and the gallate moiety contributed to the growth inhibition and AP-1 activity; the galloyl structure appeared to have a stronger effect on the inhibitory action than the gallate moiety. The epimers of the catechins showed similar inhibitory effects on AP-1 activity. The addition of catalase to the incubation of the cells with EGCG or TFdiG did not prevent the inhibitory effect on AP-1 activity, suggesting that H2O2 does not play a significant role in the inhibition by tea polyphenols. Both EGCG and TFdiG inhibited the phosphorylation of p44/42 (extracellular signal-regulated kinase 1 and 2) and c-jun without affecting the levels of phosphorylated-c-jun-NH2-terminal kinase. TFdiG inhibited the phosphorylation of p38, but EGCG did not. EGCG lowered the level of c-jun, whereas TFdiG decreased the level of fra-1. These results suggest that tea polyphenols inhibited AP-1 activity and the mitogen-activated protein kinase pathway, which contributed to the growth inhibition; however, different mechanisms may be involved in the inhibition by catechins and theaflavins.  (+info)

Protection against peroxynitrite by cocoa polyphenol oligomers. (5/171)

Flavonoids, natural plant constituents, protect against peroxynitrite and can thereby play a role in defense against this mediator of inflammation. Procyanidin oligomers of different size (monomer through nonamer), isolated from the seeds of Theobroma cacao, were examined for their ability to protect against peroxynitrite-dependent oxidation of dihydrorhodamine 123 and nitration of tyrosine. By molarity, oligomers were more effective than the monomeric epicatechin; the tetramer was particularly efficient at protecting against oxidation and nitration reactions. These results suggest that epicatechin oligomers found in cocoa powder and chocolate may be a potent dietary source for defense against peroxynitrite.  (+info)

Procyanidin content and variation in some commonly consumed foods. (6/171)

Procyanidins are a subclass of flavonoids found in commonly consumed foods that have attracted increasing attention due to their potential health benefits. However, little is known regarding their dietary intake levels because detailed quantitative information on the procyanidin profiles present in many food products is lacking. Therefore, the procyanidin content of red wine, chocolate, cranberry juice and four varieties of apples has been determined. On average, chocolate and apples contained the largest procyanidin content per serving (164.7 and 147.1 mg, respectively) compared with red wine and cranberry juice (22.0 and 31.9 mg, respectively). However, the procyanidin content varied greatly between apple samples (12.3-252.4 mg/serving) with the highest amounts on average observed for the Red Delicious (207.7 mg/serving) and Granny Smith (183.3 mg/serving) varieties and the lowest amounts in the Golden Delicious (92.5 mg/serving) and McIntosh (105.0 mg/serving) varieties. The compositional data reported herein are important for the initial understanding of which foods contribute most to the dietary intake of procyanidins and may be used to compile a database necessary to infer epidemiological relationships to health and disease.  (+info)

Cocoa procyanidins and human cytokine transcription and secretion. (7/171)

We examined whether cocoa, in its isolated procyanidin fractions (monomer through decamer), would modulate cytokine production at the levels of transcription and protein secretion in both resting and phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMC). In resting cells, interleukin (IL)-1beta and IL-4 gene expression from cocoa-treated cells varied markedly among the subjects tested. However, at the protein level, the larger fractions (pentamer through decamer) stimulated a dramatic increase in IL-1beta concentration (up to ninefold) with increasing degree of polymerization. Similarly, these larger fractions augmented IL-4 concentration by as much as 2 pg/ml, whereas the control displayed levels nearly undetectable. In the presence of PHA, gene expression also seemed to be most affected by the larger procyanidin fractions. The pentameric through decameric fractions increased IL-1 beta expression by 7-19% compared with PHA control, whereas the hexameric through decameric fractions significantly inhibited PHA-induced IL-4 transcription in the range of 71-86%. This observation at the transcription level for IL-1 beta was reflected at the protein level in PHA-stimulated PBMC. Significant reductions in mitogen-induced IL-4 production were also seen at the protein level with the hexamer, heptamer and octamer. Individual oligomeric cocoa fractions were unstimulatory for IL-2 in resting PBMC. However, when induced with PHA, the pentamer, hexamer and heptamer fractions caused a 61-73% inhibition in IL-2 gene expression. This study offers additional data for the consideration of the health benefits of dietary polyphenols from a wide variety of foods, including those benefits associated specifically with cocoa and chocolate consumption.  (+info)

Reactions of peroxynitrite with cocoa procyanidin oligomers. (8/171)

Peroxynitrite is a mediator molecule in inflammation, and its biological properties are being studied extensively. Flavonoids, which are natural plant constituents, protect against peroxynitrite and thereby could play an anti-inflammatory role. Procyanidin oligomers of different sizes (monomer through nonamer), isolated from the seeds of Theobroma cacao, were recently examined for their ability to protect against peroxynitrite-dependent oxidation of dihydrorhodamine 123 and nitration of tyrosine and were found to be effective in attenuating these reactions. The tetramer was particularly efficient at protecting against oxidation and nitration reactions. Epicatechin oligomers found in cocoa powder and chocolate may be a potent dietary source for defense against peroxynitrite.  (+info)

Biflavonoids are a type of flavonoid, which are plant-based compounds with antioxidant properties. Biflavonoids are unique because they consist of two flavonoid molecules joined together. They can be found in various plants, including fruits, vegetables, and herbs. Some research suggests that biflavonoids may have potential health benefits, such as reducing inflammation and protecting against oxidative stress. However, more research is needed to confirm these effects and determine the optimal dosages for human consumption.

Garcinia is a genus of flowering plants in the family Clusiaceae. It includes several species that are used in traditional medicine and as dietary supplements. One of the most well-known species is Garcinia cambogia, also known as Malabar tamarind, which contains hydroxycitric acid (HCA) in its fruit rind. HCA is a chemical that has been promoted as a weight loss aid, although its effectiveness is still a matter of scientific debate.

It's important to note that while some Garcinia species have potential health benefits, they can also have side effects and interact with certain medications. Therefore, it's always recommended to consult with a healthcare provider before starting any new supplement regimen.

I apologize for any confusion, but "Daphne" is not a medical term or condition. It is a name that can refer to both males and females in Greek mythology and is also used as a given name in modern times. In botany, "Daphne" refers to a genus of shrubs in the thyme family. If you have any questions about a specific medical topic, I would be happy to help clarify or explain it for you.

I'm not aware of a medical definition for the term "Cycas." It is a genus name in botany, referring to a group of plants commonly known as cycads. Cycads are ancient seed plants that have been on Earth for millions of years. They are often grown as ornamental plants due to their unique appearance.

While there may not be a direct medical definition for "Cycas," it is worth noting that some parts of the cycad plant, particularly the seeds, contain toxic compounds that can cause serious health issues in both humans and animals if ingested. These toxins can affect the nervous system, liver, and kidneys, leading to symptoms such as vomiting, seizures, and even death in severe cases.

Therefore, while "Cycas" may not have a medical definition per se, it is still important to be aware of its potential health risks.

Prenylation is a post-translational modification process in which a prenyl group, such as a farnesyl or geranylgeranyl group, is added to a protein covalently. This modification typically occurs at a cysteine residue within a CAAX motif (C is cysteine, A is an aliphatic amino acid, and X is any amino acid) found at the carboxyl-terminus of the protein. Prenylation plays a crucial role in membrane association, protein-protein interactions, and intracellular trafficking of proteins, particularly those involved in signal transduction pathways.

A plant extract is a preparation containing chemical constituents that have been extracted from a plant using a solvent. The resulting extract may contain a single compound or a mixture of several compounds, depending on the extraction process and the specific plant material used. These extracts are often used in various industries including pharmaceuticals, nutraceuticals, cosmetics, and food and beverage, due to their potential therapeutic or beneficial properties. The composition of plant extracts can vary widely, and it is important to ensure their quality, safety, and efficacy before use in any application.

Flavonoids are a type of plant compounds with antioxidant properties that are beneficial to health. They are found in various fruits, vegetables, grains, and wine. Flavonoids have been studied for their potential to prevent chronic diseases such as heart disease and cancer due to their ability to reduce inflammation and oxidative stress.

There are several subclasses of flavonoids, including:

1. Flavanols: Found in tea, chocolate, grapes, and berries. They have been shown to improve blood flow and lower blood pressure.
2. Flavones: Found in parsley, celery, and citrus fruits. They have anti-inflammatory and antioxidant properties.
3. Flavanonols: Found in citrus fruits, onions, and tea. They have been shown to improve blood flow and reduce inflammation.
4. Isoflavones: Found in soybeans and legumes. They have estrogen-like effects and may help prevent hormone-related cancers.
5. Anthocyanidins: Found in berries, grapes, and other fruits. They have antioxidant properties and may help improve vision and memory.

It is important to note that while flavonoids have potential health benefits, they should not be used as a substitute for medical treatment or a healthy lifestyle. It is always best to consult with a healthcare professional before starting any new supplement regimen.

Chinese herbal drugs, also known as traditional Chinese medicine (TCM), refer to a system of medicine that has been practiced in China for thousands of years. It is based on the belief that the body's vital energy, called Qi, must be balanced and flowing freely for good health. TCM uses various techniques such as herbal therapy, acupuncture, dietary therapy, and exercise to restore balance and promote healing.

Chinese herbal drugs are usually prescribed in the form of teas, powders, pills, or tinctures and may contain one or a combination of herbs. The herbs used in Chinese medicine are typically derived from plants, minerals, or animal products. Some commonly used Chinese herbs include ginseng, astragalus, licorice root, and cinnamon bark.

It is important to note that the use of Chinese herbal drugs should be under the guidance of a qualified practitioner, as some herbs can interact with prescription medications or have side effects. Additionally, the quality and safety of Chinese herbal products can vary widely depending on the source and manufacturing process.

Herbal medicine, also known as botanical medicine or phytomedicine, refers to the use of plants and plant extracts for therapeutic purposes. This traditional form of medicine has been practiced for thousands of years across various cultures worldwide. It involves the utilization of different parts of a plant, such as leaves, roots, seeds, flowers, and fruits, either in their whole form or as extracts, infusions, decoctions, tinctures, or essential oils.

Herbal medicines are believed to contain active compounds that can interact with the human body, influencing its physiological processes and helping to maintain or restore health. Some herbs have been found to possess pharmacological properties, making them valuable in treating various ailments, including digestive disorders, respiratory conditions, sleep disturbances, skin issues, and cardiovascular diseases.

However, it is essential to note that the regulation of herbal medicines varies significantly between countries, and their safety, efficacy, and quality may not always be guaranteed. Therefore, consulting a healthcare professional before starting any herbal medicine regimen is advisable to ensure proper usage, dosage, and potential interactions with other medications or health conditions.

Traditional Chinese Medicine (TCM) is a system of medicine that has been developed in China over thousands of years. It is based on the philosophy that the body's vital energy (Qi) circulates through a network of channels called meridians, and that disease results from an imbalance or blockage in this flow of Qi.

TCM uses a variety of treatments to restore balance and promote health, including acupuncture, herbal medicine, moxibustion (the burning of herbs near the skin), cupping, dietary therapy, and tuina (Chinese massage). The use of Chinese herbal medicines is a major component of TCM, with formulas often consisting of combinations of several different herbs tailored to the individual patient's needs.

In addition to these treatments, TCM practitioners may also use diagnostic techniques such as pulse diagnosis and tongue examination to assess a person's overall health and determine the underlying cause of their symptoms. The goal of TCM is not only to treat specific symptoms or diseases but to address the root causes of illness and promote overall wellness.

Phytotherapy is the use of extracts of natural origin, especially plants or plant parts, for therapeutic purposes. It is also known as herbal medicine and is a traditional practice in many cultures. The active compounds in these plant extracts are believed to have various medicinal properties, such as anti-inflammatory, analgesic, or sedative effects. Practitioners of phytotherapy may use the whole plant, dried parts, or concentrated extracts to prepare teas, capsules, tinctures, or ointments for therapeutic use. It is important to note that the effectiveness and safety of phytotherapy are not always supported by scientific evidence, and it should be used with caution and preferably under the guidance of a healthcare professional.

"Poria" is not a term commonly used in medical terminology. However, it might be a reference to "Poria cocos," a type of fungus that is sometimes used in traditional Chinese medicine. In this context, "Poria" is said to have anti-inflammatory, diuretic, and sedative properties, although its efficacy and safety are not well-studied or established by modern medical standards.

It's important to note that the use of traditional herbal remedies like "Poria cocos" can interact with other medications and have side effects, so it's crucial to consult with a healthcare provider before using them.

Medicinal plants are defined as those plants that contain naturally occurring chemical compounds which can be used for therapeutic purposes, either directly or indirectly. These plants have been used for centuries in various traditional systems of medicine, such as Ayurveda, Chinese medicine, and Native American medicine, to prevent or treat various health conditions.

Medicinal plants contain a wide variety of bioactive compounds, including alkaloids, flavonoids, tannins, terpenes, and saponins, among others. These compounds have been found to possess various pharmacological properties, such as anti-inflammatory, analgesic, antimicrobial, antioxidant, and anticancer activities.

Medicinal plants can be used in various forms, including whole plant material, extracts, essential oils, and isolated compounds. They can be administered through different routes, such as oral, topical, or respiratory, depending on the desired therapeutic effect.

It is important to note that while medicinal plants have been used safely and effectively for centuries, they should be used with caution and under the guidance of a healthcare professional. Some medicinal plants can interact with prescription medications or have adverse effects if used inappropriately.

I'm sorry for any confusion, but "Local Area Networks" (LANs) are not a medical term. They are a common term in the field of computer networking. Here is a general definition:

A Local Area Network (LAN) is a network that connects computers and other devices in a relatively small area, typically a single building or a group of buildings. Most LANs are used to share resources such as printers, games or applications. A LAN is usually owned, created, managed and supported by a single organization, such as a school, hospital, or business.
