Its abuse is associated with cognitive dysfunctions and increased resistance to blood flow in the cerebral vasculature. In addition, MJ abuse is associated with increased risks of potentially serious cardiovascular disorders. Indeed, MJ users showed significant increases in three protein peaks, which were identified as three isoforms of apolipoprotein apo C-III. Immunoprecipitation using an apoC-III antibody also validated the identification of the proteins. In any case, because apoC-III is a cardiovascular risk factor, the increased levels observed in MJ users might explain, in part, the cardiac and cerebral abnormalities reported in these patients. Keywords: cannabis, apolipoproteins, protein profiling, cerebrovascular and cardiovascular risk factors. Marijuana MJ is the most commonly used illicit drug in the United States, with 4. It is also possible that some of these proteins might be responsible, in part, for some of the adverse effects reported as a consequence of prolonged MJ abuse. As a first step toward testing these ideas, we decided to make use of a proteomic approach that has been adapted for analysis and characterization of overall protein expression in the plasma, other body fluids and various cell extracts. That approach has allowed researchers to successfully identify unique protein biomarkers for cancers of the ovary, 21 prostate, 22 , 23 mammary glands 24 and for the pathophysiology of schizophrenia. Eighteen MJ users and 24 control subjects were used in the present study. The demographic data for these volunteers are given in Table 1. All volunteers had undergone medical, neurological, psychological and laboratory evaluations. Exclusion criteria that applied to all subjects include: 1 major medical and psychiatric illnesses including history of hypertension, 2 head injuries with loss of consciousness for greater than 5 min, 3 evidence of any neurological abnormalities by history or examination, 4 HIV seropositivity and 5 drug cocaine, heroin and so on or excessive alcohol use by DSM-IV criteria for alcohol abuse or dependence. In addition to self report, the use of other illicit drugs was also ruled out by obtaining at least two observed urine samples for toxicological examinations during screening visits. These standard toxicological examinations did not document the presence of any illicit drugs that is, amphetamine, barbiturates, benzodiazepines, CBs, cocaine metabolites, methadone, opiates and phencyclidine in any study participant, except for CBs for the MJ group. The detection threshold for a positive screen for CBs was 50 mg per ml. Informed consent was obtained from all subjects. These patients have been the subject of previous papers from this laboratory. The number of days of substance use in the last 30 days from the ASI. Years of substance use calculated from ASI. In addition to the medical history, demographic information and drug use history information were obtained from the Addiction Severity Index. The heavy users smoked the equivalent of Blood samples were obtained in 7 ml Kendal vacutainer glass purple top tubes BD following venous blood sample procedures. Serum samples were pre-fractionated using pH gradients prior to analysis. Pre-fractionation has been shown to increase the number of detected peaks 29 and, thus, can increase the probability of identifying peptides or proteins that are differentially expressed. The samples were diluted twice in binding buffer, and loaded on the spin column and incubated under shaking for half an hour at room temperature. The column was centrifuged at low speed r. Then, a sequential fractionation of the column with a decreasing buffer pH pH 9; pH 7; pH 5; pH 4; pH 3; organic solvent was performed. Each solution was incubated for 20 min on the column. This spotting allows the visualization of the different proteins in each fraction to localize the proteins of interest. Reference serum samples were also spotted along with the subject's fractionated serum samples. The serum was incubated with the chips for 1 h with vigorous shaking. A final rinse with deionized water was performed, the bioprocessor was removed and the chips were allowed to air dry for 30 min. The SPA solution was allowed to dry completely 15 min interval before it was added for a second time. ProteinChip Reader calibration in the low to high mass range was performed using All-in-1 protein standard II prior to obtain the most accurate mass readings possible. The raw data were transferred to ProteinChip Software Version 3. Spectra were calibrated with the same external calibrants IgG; albumin; enolase; carbonic anhydrase; myoglobin; Cytochrome c; hirudine— All-in-1 peptide standard II; Ciphergen Biosystems used for instrument calibration. Peak intensities were normalized to total ion current, excluding the mass range below Da, which is composed of strong signals from the matrix. Each spectrum was rescaled by a normalization factor, which was based on the average total ion current. Spectra were deleted if the normalization factor was more than two times higher or lower than the mean normalization factor. The signal-to-noise cutoff was set at 3 for the first pass of peak detection to pick up obvious and well-defined peaks and 1. After the above processing, mass spectral data were used for expression difference mapping using the Ciphergen ProteinChip software system Ciphergen Biosystems , which provides rapid statistical analysis of multiple samples to identify peaks with differential intensities. The first step in the statistical analysis of peak intensity was to carry out biomarker wizard analysis on calibrated and normalized data. To average the triplicate data export the biomarker wizard analysis as a. Each cluster then was treated as a single protein or peptide fragment. Intensities of clustered peaks were analyzed by Student's t -test between two sample groups. The experiments were performed blind to diagnosis. Mass spectra were generated, calibrated by external calibrants All-in-1 protein standard II, Ciphergen Biosystems and normalized by total ion current. Among the three peaks that were identified, we enriched the peak 9. Samples were then centrifuged for 1 min at r. Proteins in the eluted fractions were analyzed by profiling aliquots of each fraction on to a NP20 ProteinChip Array. This fraction was further concentrated by vacuum centrifugation and dissolved in sample buffer for sodium dodecyl sulphate-polyacrylamide gel electrophoresis SDS-PAGE. This was stained overnight using colloidal Coomassie blue Safe-stain, Invitrogen and then destained with deionized water. The gel spot was extracted and used for passive elution or for in-gel digestion. Aliquots of the samples were analyzed directly on a NP20 array. To confirm the identity of the biomarker, we used immunocapture assays. The washes were followed by addition of mM acetic acid. Potential differences between the controls and the MJ users were assessed using analysis of covariance ANCOVA with gender, ethnicity, monthly alcohol use and daily tobacco use as co-variates. These covariates were used to statistically control for small ethnic and gender sampling differences observed between the two groups. They were used to control for slightly heavier use of alcohol and tobacco by the MJ users. Post-hoc analyses were done using Student's t -test. Analyses were performed using SPSS version By using Biomarkers Patterns, decision trees were made and the decision trees generated from the fraction 6 samples resulted in a superior classification. All data from fraction 6 were reproduced at least three times, thus, ensuring a good level of confidence in our observations. Gender, ethnicity daily tobacco and monthly alcohol use did not contribute to the differences observed between the control and MJ group as these covariates were not significant in these analyses. Variation of intensity between patients and controls are visible at approximately 9. The intensity values for the 9. As shown in the cluster plot in Figure 1b , the 9. The marker is indicated with an arrow. Note the different sizes of the peaks in the control and MJ groups. The bands at 9. Note the lack of overlap between the two groups, with the MJ group showing higher values. Isolation and enrichment of the identified 9. The three bands are shown in Figure 3a. The three protein bands were excised and the proteins were passively eluted from the gel pieces, and their masses were verified by MS profiling Figure 3b , which confirms the SELDI-TOF-protein profile results. Confirmation of the identity of the 9. The left lane shows the marker, the middle lane shows the control sample and the right lane shows the MJ sample. The bands which were excised are indicated by arrows. These results confirm the identity of the excised proteins. Identification of the 9. The protease digest was subjected to tandem mass spectrometry. The same protein purification and identification were repeated on four control and four MJ users serum samples, and each time the excised protein band was identified as apoC-III. Although the purification technique and further identification using tandem MS analysis showed consistently that the putative protein marker was apoC-III, we chose to further confirm its identity by specific immunoaffinity capture on ProteinChip arrays containing polyclonal anti-sera recognizing apoC-III Figure 5. Confirmation of biomarker using anti-apoC-III antibody. After washing, serum was incubated with serum diluted in PBS. Eluted fractions were profiled on NP20 arrays. Note the differences in the scales representing the control and MJ marijuana groups. In a fashion similar to the observation in Figure 1 , the peaks in the MJ group were higher than those of the control group. Because apoC-III and triglyceride levels are known to show positive correlations, we decided to measure triglyceride levels in the serum collected from these participants. Table 3 shows that the triglyceride levels showed non-significant increases in the serum of MJ users. Gender, ethnicity, daily tobacco and monthly alcohol use did not contribute to these findings as these covariates were not significant in these analyses. The main finding of the present study is that chronic MJ abuse is associated with significant increases in serum apoC-III levels. In addition, there were significant correlations between apoC-III and triglyceride levels. Because of the relationship between apoC-III levels and vascular risk factors, the observations in MJ abusers will be discussed in terms of the potential relevance to MJ-induced adverse vascular events, which include coronary abnormalities. ApoC-III is a 79 amino-acid glycoprotein that contains galactose, as its sugar moiety. The increased serum apoC-III levels in MJ users and the positive correlations between serum apoC-III and triglyceride levels observed in the present study are consistent with the findings of a previous paper that had reported significant increases in serum HDL-triglyceride concentrations in MJ users in comparison to controls. However, recent clinical data have demonstrated significant effects of CB1 receptor signaling on lipid parameters. Specifically, treatment of obese patients with the CB1 receptor blocker, rimonabant, caused significant improvements in the levels of triglycerides. The possibility that MJ exerts its actions via stimulation of CB1 receptors is supported by experiments documenting promotion of lipogenesis in the rodent liver by the CB1 agonist, HU and its reversal by pretreatment with the CB1 blocker, rimonabant. Marijuana is the most commonly abused drug in the USA and evidence exists that its abuse is a risk factor for cardiovascular and cerebrovascular disorders.
