Effects of a standardized Bacopa monnieri extract on cognitive performance, anxiety, and depression in the elderly: a randomized, double-blind, placebo-controlled trial.

July 2008

OBJECTIVES:
Study aims were to evaluate effects of Bacopa monnieri whole plant standardized dry extract on cognitive function and affect and its safety and tolerability in healthy elderly study participants.
DESIGN:
The study was a randomized, double-blind, placebo-controlled clinical trial with a placebo run-in of 6 weeks and a treatment period of 12 weeks. Setting/location: Volunteers were recruited from the community to a clinic in Portland, Oregon by public notification.
SUBJECTS:
Fifty-four (54) participants, 65 or older (mean 73.5 years), without clinical signs of dementia, were recruited and randomized to Bacopa or placebo. Forty-eight (48) completed the study with 24 in each group. INTERVENTIONS: Standardized B. monnieri extract 300 mg/day or a similar placebo tablet orally for 12 weeks. OUTCOME MEASURES: The primary outcome variable was the delayed recall score from the Rey Auditory Verbal Learning Test (AVLT). Other cognitive measures were the Stroop Task assessing the ability to ignore irrelevant information, the Divided Attention Task (DAT), and the Wechsler Adult Intelligence Scale (WAIS) letter-digit test of immediate working memory. Affective measures were the State-Trait Anxiety Inventory, Center for Epidemiologic Studies Depression scale (CESD)-10 depression scale, and the Profile of Mood States. Vital signs were also monitored.
Results:
Controlling for baseline cognitive deficit using the Blessed Orientation-Memory-Concentration test, Bacopa participants had enhanced AVLT delayed word recall memory scores relative to placebo. Stroop results were similarly significant, with the Bacopa group improving and the placebo group unchanged. CESD-10 depression scores, combined state plus trait anxiety scores, and heart rate decreased over time for the Bacopa group but increased for the placebo group. No effects were found on the DAT, WAIS digit task, mood, or blood pressure. The dose was well tolerated with few adverse events (Bacopa n = 9, placebo n = 10), primarily stomach upset. CONCLUSIONS: This study provides further evidence that B. monnieri has potential for safely enhancing cognitive performance in the aging.

gamma-Tocotrienol prevents oxidative stress-induced telomere shortening in human fibroblasts derived from different aged individuals.

January 2010

The effects of palm gamma-tocotrienol (GGT) on oxidative stress-induced cellular ageing was investigated in normal human skin fibroblast cell lines derived from different age groups; young (21-year-old, YF), middle (40-year-old, MF) and old (68-year-old, OF). Fibroblast cells were treated with gamma-tocotrienol for 24 hours before or after incubation with IC50 dose of H2O2 for 2 hours. Changes in cell viability, telomere length and telomerase activity were assessed using the MTS assay (Promega, USA), Southern blot analysis and telomere repeat amplification protocol respectively. Results showed that treatment with different concentrations of gamma-tocotrienol increased fibroblasts viability with optimum dose of 80 microM for YF and 40 microM for both MF and OF. At higher concentrations, gamma-tocotrienol treatment caused marked decrease in cell viability with IC50 value of 200 microM (YF), 300 microM (MF) and 100 microM (OF). Exposure to H2O2 decreased cell viability in dose dependent manner, shortened telomere length and reduced telomerase activity in all age groups. The IC50 of H2O2 was found to be; YF (700 microM), MF (400 microM) and OF (100 microM). Results showed that viability increased significantly (p<0.05) when cells were treated with 80 microM and 40 microM gamma-tocotrienol prior or after H2O2-induced oxidative stress in all age groups. In YF and OF, pretreatment with gamma-tocotrienol prevented shortening of telomere length and reduction in telomerase activity. In MF, telomerase activity increased while no changes in telomere length was observed. However, post-treatment of gamma-tocotrienol did not exert any significant effects on telomere length and telomerase activity. Thus, these data suggest that gamma-tocotrienol protects against oxidative stress-induced cellular ageing by modulating the telomere length possibly via telomerase.

Anti-aging effects of cyanidin under a stress-induced premature senescence cellular system.

January 2010

The anti-aging effects of cyanidin were investigated under stress-induced premature senescence (SIPS) using WI-38 human diploid fibroblasts. WI-38 cells that were treated with 300 microM H(2)O(2) showed losses of cell viability, increased lipid peroxidation, and shortened cell lifespans. However, treatment with cyanidin attenuated cellular oxidative stress through increase of cell viability and the inhibition of lipid peroxidation. In addition, the life spans of young-, middle-, and old-aged WI-38 cells were prolonged by cyanidin treatment. Furthermore, H(2)O(2)-treated WI-38 cells significantly increased mRNA and protein expressions of nuclear factor-kappaB, cyclooxygenase-2, and inducible nitric oxide synthase, while those treated with cyanidin had significantly decreased expressions. These results suggest that cyanidin may delay the aging process by attenuating oxidative stress under the SIPS cellular model.

Senile hair graying: H2O2-mediated oxidative stress affects human hair color by blunting methionine sulfoxide repair.

June 2009

Senile graying of human hair has been the subject of intense research since ancient times. Reactive oxygen species have been implicated in hair follicle melanocyte apoptosis and DNA damage. Here we show for the first time by FT-Raman spectroscopy in vivo that human gray/white scalp hair shafts accumulate hydrogen peroxide (H(2)O(2)) in millimolar concentrations. Moreover, we demonstrate almost absent catalase and methionine sulfoxide reductase A and B protein expression via immunofluorescence and Western blot in association with a functional loss of methionine sulfoxide (Met-S=O) repair in the entire gray hair follicle. Accordingly, Met-S=O formation of Met residues, including Met 374 in the active site of tyrosinase, the key enzyme in melanogenesis, limits enzyme functionality, as evidenced by FT-Raman spectroscopy, computer simulation, and enzyme kinetics, which leads to gradual loss of hair color. Notably, under in vitro conditions, Met oxidation can be prevented by L-methionine. In summary, our data feed the long-voiced, but insufficiently proven, concept of H(2)O(2)-induced oxidative damage in the entire human hair follicle, inclusive of the hair shaft, as a key element in senile hair graying, which does not exclusively affect follicle melanocytes. This new insight could open new strategies for intervention and reversal of the hair graying process.

Inhibitory effect of resveratrol derivative BTM-0512 on high glucose-induced cell senescence involves dimethylaminohydrolase/asymmetric dimethylarginine pathway.

May 2010

1. It has been reported that resveratrol exerts the inhibitory effects on aging through activation of sirtuin 1 (SIRT1) and dimethylarginine dimethylaminohydrolase (DDAH)/asymmetric dimethylarginine (ADMA) pathway involved in the high glucose-induced endothelial cell senescence. 2. The aims of this work were to explore whether BTM-0512, a novel derivative of resveratrol, was able to exert the beneficial effect on high glucose-induced cellular senescence through regulating the DDAH/ADMA pathway and to explore whether the regulatory effect of BTM-0512 on DDAH/ADMA pathway was related to the activation of SIRT1. 3. The senescence model of endothelial cells was induced by high glucose and the cells were collected for the determination of beta-galactosidase and DDAH activity, ADMA level, DDAH and SIRT1 mRNA expression. 4. The results showed that high glucose significantly increased the ratio of senescent cells concomitantly with the decreased DDAH activity, the downregulated DDAH2 and SIRT1 mRNA expressions and the increased ADMA levels, which were attenuated by pretreatment with BTM-0512. 5. The beneficial effects of BTM-0512 on high glucose-induced senescence were blocked by splimtomicin, the specific inhibitor of SIRT1, or by silencing DDAH2 expression. 6. The results suggest that BTM-0512 was able to exert the beneficial effects on high glucose-induced cellular senescence through regulating the DDAH/ADMA pathway, and its regulatory effect on DDAH/ADMA pathway was related to the activation of SIRT1.

Estrogen reduces endothelial progenitor cell senescence through augmentation of telomerase activity.

September 2005

Background:
Recent studies have demonstrated that aging or senescence constitutes a potential limitation to the ability of endothelial progenitor cells (EPCs) to sustain ischemic tissue and repair. Conversely, estrogens have been shown to accelerate recovery of the endothelium after vascular injury. OBJECTIVE:
To investigate whether estrogens are able to prevent senescence of EPCs. METHODS AND
Results:
Human EPCs were isolated from peripheral blood and characterized. After ex-vivo cultivation, the cells became senescent as determined by acidic beta-galactosidase staining. 17beta-estradiol dose-dependently inhibited the onset of EPC senescence in culture. Because cellular senescence is critically influenced by telomerase, which elongates telomeres, we measured telomerase activity using a polymerase chain reaction (PCR)-enzyme-linked immunosorbent assay (ELISA) technique. 17beta-estradiol significantly increased telomerase activity. Interestingly, reverse transcriptase-PCR analysis demonstrated that 17beta-estradiol dose-dependently increased the catalytic subunit, telomerase reverse transcriptase (TERT) – an effect that was significantly inhibited by pharmacological phosphatidylinositol 3-kinase (PI3-K) blockers (either wortmannin or LY294002). Because the expression of TERT is regulated by the PI3-K/Akt pathway, we examined the effect of 17beta-estradiol on Akt activity in EPCs. Immunoblotting analysis revealed that 17beta-estradiol dose-dependently led to phosphorylation and, thus, to activation of Akt in EPCs. We also examined whether the protective effect of 17beta-estradiol on EPC senescence translates into the augmentation of mitogenic activity in EPCs. A [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenol)-2-(4-sulfophenyl)-2H-tetrazolium] (MTS) assay demonstrated that the mitogenic potential in EPCs treated with 17beta-estradiol exceeded that in untreated (control) EPCs (P
