DV Biologics, a Leading Biological company, Reports Earth Science Tech (ETST) High Grade Hemp CBD (Cannabidiol) Oil Deters the Formation of Reactive Oxygen Species (ROS) on Human Brain Cells: May serve as a Neuroprotectant

BOCA RATON, FL / ACCESSWIRE / August 18, 2015 / Earth Science Tech, Inc. ("ETST" or "the Company"), a unique biotechnology company focused on nutraceuticals, bioceuticals and dietary supplements, announced today that DV Biologics, a leading biological company, has confirmed ETST High Grade Hemp CBD (Cannabidiol) Oil deterred the formation of reactive oxygen species and cell death in human brain cells in vitro. The goal of these studies is to test if ETST High Grade Hemp CBD (Cannabidiol) Oil, as a dietary supplement, serves as a neuroprotectant which may help with neurodegenerative disorders such as Alzheimer's and Parkinson's. The scientific study which concludes the in vitro experiments done independently on human brain cells by DV Biologics, a company that provides biological tools and research for the advancement of medicine, illustrates that using ETST High Grade Hemp CBD (Cannabidiol) Oil can rescue human brain cells from the detrimental effects of reactive oxygen species and free radical formation which cause damage to brain cells (see study below). Recently, independent studies demonstrated that ETST High Grade Hemp CBD (Cannabidiol) Oil can reduce lipid peroxidation (oxidative stress) on human brain cells following the addition of hydrogen peroxide. This new data supports and extends the previous data that ETST High Grade Hemp CBD (Cannabidiol) Oil may help serve as a neuroprotectant. This study looks at another pathway of free radical formation, oxidative stress and cell death that occurs in the brain during neurodegenerative disorders such as Alzheimers and Parkinsons. This data suggest that ETST High Grade Hemp CBD (Cannabidiol) Oil may have neuroprotective properties.

"Here at ETST we will continue focusing on providing the best All-Natural High Grade Hemp CBD (Cannabidiol) Oil as a dietary supplement. We believe the only way to do this is by studying the effects of ETST High Grade Hemp CBD Oils in various experiments. Science is what will show the world that ETST provides high quality products as well as the best All-Natural High Grade Hemp CBD (Cannabidiol) Oil designed to give consumers maximum overall wellness benefits. We have relatively exciting studies which we will be starting soon in our continual goal of providing the best products for consumers worldwide and great value to our investors," stated Matthew Cohen, CEO of ETST.

According to Dr Rafael Gonzalez, VP of Research & Development at DV Biologics, "The data speaks for itself. This in vitro study is very encouraging as it demonstrates that ETST High Grade Hemp CBD (Cannabidiol) Oil may be beneficial for the brain. The great thing is that the data is supported by 3 different experiments, all showing the same result that it works. With this data if I had a neurodegenerative disorder such as Parkinsons, I would seriously consider taking this as there isnt much available that can deter the progression of the disorder. We hope that ETST will continue to give us the opportunity to work with their High Grade Hemp CBD (Cannabidiol) Oil."

Does Earth Science Tech High Grade Cannabidiol (CBD) Rich Hemp Oil Have a Neuroprotective Effect? The DV Biologics Report and data below is encouraging and clearly demonstrates that Earth Science Technology (ETST) High Grade HEMP CBD (Cannabidiol) Oil is protective against lipid peroxidation in human brain cells in vitro.

The Brain

The brain contains trillions of cells. From neurons with its long axons (nerve fibers) which can extend greater than 2 feet and serve to communicate to glial cells which support the brain in all its complex task. Two-thirds of the brain is composed of lipids. The vast majority of the different cell types in the brain require lipids for correct transmission of signals, providing energy and structural support to our cell membranes. Cells in the body and particularly in the brain are under constant attack by free radicals and oxidative stress. There are protective mechanisms that help deter this normal damage that occurs; however, with aging the protective mechanism declines substantially and degeneration of the brain occurs.

Lipid Peroxidation

Lipid peroxidation is the degradation of lipids that occurs as a result of oxidative damage and is a useful marker for oxidative stress. Lipids are susceptible to an oxidative attack, typically by reactive oxygen species, resulting in a well-defined chain reaction with the production of end products such as malondialdehyde (MDA).

Reactive oxygen species (ROS)

Reactive oxygen species are molecules that contain oxygen that are chemically active (i.e. oxygen ions and peroxides). They are formed as a natural byproduct of metabolism in our bodies. However, during stress and disease or dysfunction, these byproducts are not taken removed correctly and damage occurs in our body. The harmful effect of ROS occurs in cells in the form of DNA damage and oxidation of amino acids in proteins. ROS come in various forms such as superoxides and hydroxyl radicals and it is well documented that ROS play a crucial role in the formation of neurodegenerative disorders, cancer and aging.

Experiment:

In this experiment, we look at three (3) different parameters:

1. Fluorometric intracellular ROS with a Kit that provides a sensitive, one-step fluorometric assay to detect intracellular ROS (especially superoxide and hydroxyl radicals) after induction of peroxidation with hydrogen peroxide (with and without ETST High Grade Hemp CBD (Cannabidiol) Oil).

2. Lipid peroxidation is determined by the reaction of MDA with thiobarbituric acid (TBA) to form a fluorometric complex, proportional to the amount of MDA present, after induction of peroxidation with hydrogen peroxide (with and without ETST High Grade Hemp CBD (Cannabidiol) Oil).

3. Neutral Red Assay to determine viability of cells after induction of peroxidation with hydrogen peroxide (with and without ETST High Grade Hemp CBD (Cannabidiol) Oil).

Experimental procedure ROS:

*Cells were plated in 96 well until it reach 90%. Neural cells were at a density of 2 X 104 cells/cm2. The cells were grown in neural media supplemented with 20 ng/ml of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF)
*Media was changed every 2-3 days.
*ETST Hemp CBD/Neural-Growth media was prepared by diluting the ETST Hemp CBD in dimethyl sulfoxide (DMSO). The suspension was filtered with a 0.22 micron filter. The ETST Hemp CBD suspension was then diluted in N-GRO media to contain the following concentrations of Hemp CBD: 5 M, 2.5 M, and 1 M CBD.
*Cells were incubated with ETST Hemp CBD for 48 hours prior to the addition of hydrogen peroxide.
*After 48 hours, ROS was induced by addition of H2O2 at concentration of 25 M to certain wells in quadruplicate. H2O2 was added to the wells of a 96 well plate according to the following design:

*Set up the Master Reaction Mix.
*Add 100 mL/well (96 well plate) Master Reaction Mix into the cell plate.
*Incubate the cells in a 5% CO2, 37 C incubator for one hour.
*Treat cells with 20 mL/well of H2O2 (96 well plate).
*For control wells (untreated cells), PBS was used.
*To induce ROS, incubate the cell plate in a 5% CO2, 37 C incubator for 16 hours.
*Measure the fluorescence intensity at lex = 490/lem = 525 nm for 1 second/well.

Experimental Procedure Lipid Peroxidation:

*Two 24-well plates were coated with Matrigel for 1 hour at 27 Celsius.
*The plates were seeded with human neural cells at a density of 2 X 104 cells/cm2. The cells were grown in neural media supplemented with 20 ng/ml of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF).
*Media was changed every 2-3 days.
*ETST Hemp CBD/Neural-Growth media was prepared by diluting the ETST Hemp CBD in dimethyl sulfoxide (DMSO). The suspension was filtered with a 0.22 micron filter. The ETST Hemp CBD suspension was then diluted in N-GRO media to contain the following concentrations of Hemp CBD: 10 M, 5 M, 2.5 M, and 1 M CBD.
*After the cells reached 80-90% confluency, base media was replaced with media containing ETST Hemp CBD or control media; the controls were media only, media with DMSO 1:100, and media with hydrogen peroxide (H2O2) (H2O2 was added during induction phase).
*The cells were incubated under experimental conditions for 48 hours in media containing ETST Hemp CBD.
*After 48 hours, lipid peroxidation was induced by addition of H2O2 at concentration of 100 M to certain wells in duplicates. H2O2 was added according to the following protocol:

*The cells were incubated with H2O2 for 120 minutes at 37 Celsius.
*Media was aspirated and the cells were lysed.
*Total protein was precipitated, and reaction to form MDA-TBA adduct was performed. The reactions were placed in a 96-well plate.
*MDA fluorometric detection was done by measuring fluorescence intensity (excitation 532 nm/ emission 553 nm) of samples and standard curve.
*Relative lipid peroxidation was measured by subtracting blank value from all readings.

Experimental Procedure Neutral Red Assay:

*Human prenatal neural cells were seeded in a 24 well flask coated with Matrigel.
*The cells were grown at 37 C, 90 % humidity, and 5.0 % CO2 until they reach 80% confluency.
*ETST Hemp CBD/Neural-Growth (N-GRO) media was prepared by diluting the ETST Hemp CBD in dimethyl sulfoxide (DMSO). The suspension was filtered with a 0.22 micron filter. The ETST Hemp CBD suspension was then diluted in N-GRO media to contain the following concentrations of Hemp CBD: 5 M, 2.5 M, and 1 M CBD.
*Cells were incubated with CBD for 48 hours prior to the addition of H2O2.
*After 48 hours, H2O2 was added at concentration of 25 M to certain wells in Duplicate. H2O2 was added according to the following protocol:

*The cells were incubated with H2O2 for 16 hours at 37 C.
*After incubation, media was aspirated from all wells and 100uL of NR medium was added to each well.
*Incubate for 1 hour with Neutral red (NR) medium at 37 C.
*NR media was aspirated from all wells and washed each well with 150uL PBS
*100 l of lysis solution (ETOH/acetic acid) solution was added to all wells, including blanks.
*Plate was shaken  rapidly on a microtiter plate shaker for 20 45 min to extract NR
*Lysis solution was transferred to a 96-well plate and absorbance was determined at 540nm in quadruplicate.

Results

Figure Legend:

Earth Science Tech (ETST) High Grade CBD (Cannabidiol) Oil rescues human brain cells from reactive oxygen species in vitro. Human brain cells were cultured and treated with ETST High Grade CBD (Cannabidiol) Oil diluted to concentrations indicated on the graph for 2 days (1.0 M CBD = 8 ppm CBD rich hemp Oil; 2.5 M CBD = 20 ppm CBD rich hemp oil; 5.0 M CBD rich hemp oil= 41 ppm Hemp Oil). The cells were treated with 25 M hydrogen peroxide (H2O2) for 16 hours and incubated with reactive oxygen species (ROS) master mix reagents for 1 hour to detect intracellular ROS.  The amount of ROS was determined by fluorescence intensity at lex = 490/lem = 525 nm.  The experiment is performed in quadruplicates, with error bars representing standard deviation error. Control: DMSO only. Positive control: Media + H2O2 + DMSO.

When brain cells are incubated with H2O2 + DMSO intracellular ROS accumulates and is much higher than normal physiological states as seen in the figure. ETST Hemp CBD on its own maintains intracellular ROS to similar levels as seen in physiological states. When ETST Hemp CBD is used prophylactically at all concentrations used (1, 2.5 and 5 M) there is a decrease in the formation of ROS.

Figure legend:

Earth Science Tech (ETST) High Grade CBD (Cannabidiol) Oil is protective against lipid peroxidation in human brain cells in vitro. Human brain cells were incubated with media (control), hydrogen peroxide (H2O2) to cause oxidative stress, DMSO which is the solvent to dilute ETST Hemp CBD in media and different concentrations of ETST Hemp CBD with and without H2O2. Error bar = Standard deviation. Control Media alone and DMSO alone. Positive control: H2O2.

When brain cells are incubated with H2O2 by itself lipid peroxidation occurs substantially as seen in the graph above. Lipid peroxidation as measured my MDA present is seen to reach greater than 2.5 nM as compared to controls of media and DMSO alone which register 0.5 nM or less. When human brain cells are treated with ETST High Grade CBD (Cannabidiol) in concentrations varying from 1 M to 10 M prior to the addition of H2O2 (prophylactically), human brain cells are protected against the damaging effects of lipid peroxidation.

Earth Science Tech (ETST) High Grade CBD (Cannabidiol) Oil deters cell death in human brain cells in vitro. Human brain cells were cultured and treated with ETST Hemp CBDemp He diluted to concentrations indicated on the graph for 2 days (1.0 M CBD = 8 ppm CBD rich hemp oil; 2.5 M CBD = 20 ppm CBD rich hemp oil; 5.0 M CBD = 41 ppm CBD rich hemp oil).  The cells were challenged with 25 M (0.85 ppm) H2O2 for 15 hours and stained with neutral red, which stains only live cells.  The amount of Neutral Red is quantified by absorbance at 540 nm.  The experiment is performed in quadruplicates, with error bars representing standard deviations. Control: Media. Positive control: Media + DMSO + H2O2.

When human brain cells are incubated with H2O2 cell death occurs as compared to normal physiological states of growing cells as measured using neutral red assay (see figure). When ETST Hemp CBD is used prophylactically at various concentrations, cell death is deterred even in the presence of H2O2.

DV Biologics Summary

Reactive oxygen species (ROS) and lipid peroxidation is damaging to human brain cells. ETST High Grade CBD (Cannabidiol) Oil in varying concentrations has shown to rescue the damaging effects of ROS and lipid peroxidation, two oxidative stress pathways that play a crucial role in various neurodegenerative disorders, cancer and aging. Moreover, ETST High Grade CBD (Cannabidiol) Oil deters cell death that occurs following the addition of hydrogen peroxide, a known ROS and lipid peroxidation inducer. This suggests a neuroprotective effect in vitro to human brain cells following the use of ETST Hemp CBD. This data merits the use of ETST High Grade CBD (Cannabidiol) Oil in human clinical studies for neurodegenerative disorders such as Alzheimers and Parkinsons.

Humans are designed with a built-in Endocannabinoid System (ECS). Research shows that many scientists believe cannabinoids work synergistically to support the whole human endo-cannabinoid system (internal and natural human cannabinoid system). It is your body's way of communicating with itself and properly regulating the way every other body system functions from your brain to your toes. The Endocannabinoid System (ECS) has shown to control pain sensation, appetite, temperature regulation, stress reactivity, immune function, and sleep as well as other processes. Even more interesting is that muscle and fat tissue also utilize these receptors to control their processes. Consumers should think of the Endocannabinoid System as one of the body's main control and command centers for tweaking your metabolism's ability to react and adapt to the world around it. Like many other nutrients in our diet, Cannabinoids can become exhausted and in need of steady dietary replenishment. Scientific studies and data show that Hemp CBD (Cannabidiol) Oil as well as all micronutrients (phytonutrients) and phyto-cannabinoids found in the oil work in harmony with the human body's own endocannabinoid system making a positive effect for overall wellness. Hemp oil contains CBD -- a non-psychoactive compound of the plant. There are millions of hemp oil consumers around the world and this number is rapidly rising with an increasing number of reports and studies showing a variety of benefits of hemp oil.
