Project description:Glandular trichomes (GT) are specialized cell factories that have the capacity to produce large amounts of metabolites which can amount to over 10% of the leaf dry weight. The specific expression of secondary metabolite pathways in glandular trichomes has facilitated their elucidation. However, little is known about the connection between central carbon and specialized metabolism in these cells. To address this question, we used the type VI glandular trichomes from a cultivated (Solanum lycopersicum LA4024) and a wild tomato accession (Solanum habrochaites LA1777) as a model. Our study is based on metabolomics, transcriptomics, proteomics and 13C-labeling datasets of trichome and leaves samples. This comparative analysis allowed us to identify specific features of trichomes in comparison to leaves. Here, the transcript raw and RMA-normalized data is hosted.

Our study is based on metabolomics, transcriptomics, proteomics and 13C-labeling datasets of trichome and leaves samples. This comparative analysis allowed us to identify specific features of trichomes in comparison to leaves. Tomato type VI trichomes are photosynthetic but acquire their carbon essentially from the leaves in the form of sucrose. Relatively high expression levels of photosystem genes and comparatively low expression of Calvin-cycle and photorespiration genes indicate that photosynthesis is used primarily to produce energy and reducing power to drive the high metabolic activity. High levels of polyunsaturated fatty acids, oxylipins, and of oxidized glutathione and high transcript and protein levels of associated enzymes further indicate a distinct capacity of GT to cope with oxidative stress. Enzymes which are involved in the supply of key precursors for the production of terpenoids both from the cytosol and in the chloroplasts are markedly increased. Finally, some enzymes that are typically associated with C4-photosynthesis are highly expressed in trichomes, suggesting that CO2 recycling processes may increase the efficiency of C usage in these cells. Based on this information we propose a model on how the glandular trichomes achieve high metabolic efficiency.

Project description:Cannabis consumption and legalization is increasing globally, raising concerns about its impact on fertility. In humans, we previously demonstrated that tetrahydrocannabinol (THC) and its metabolites reach the ovarian follicle. An extensive body of literature describes THC’s impact on sperm, however no such studies have determined its effects on the oocyte. Herein, we investigate the impact of THC on human female fertility through both a clinical and in vitro analysis. We show that follicular fluid THC concentration is positively correlated with oocyte maturation and in vitro, we observe a similar but non-significant increase following THC exposure. In vitro, we report altered expression of key genes implicated in extracellular matrix remodeling, inflammation, and chromosome segregation. Furthermore, THC induces oocyte chromosome segregation errors and increases abnormal spindle morphology. Finally, THC-positive patients exhibit significantly lower embryo euploid rates than matched controls. This study highlights potential reproductive risks associated with cannabis use in females.

Project description:Trichomes are found on the leaf surface of many plant species. They can be classified into either glandular or non-glandular types. Glandular trichomes are usually multicelluar structures and have long been known to participate in defense against pathogens through the production of specialized chemical products. Non-glandular trichomes, such as those in Arabidopsis thaliana, have been hypothesized to have roles in physical defense against insects, UV protection, detoxification, and heat dispersal. However, it has been difficult to separate a physical role from other possible functions for non-glandular trichomes. We have taken advantage of several mutants in the trichome developmental pathway and gene expression analyses to identify a set of genes expressed predominantly in Arabidopsis trichomes.

Project description:In this study, we evaluated the common proteomic profile, as well as, the exclusively deregulated proteins in ON cells from healthy controls cannabis users (HC/c), SCZ patients non-cannabis users (SCZ/nc) and SCZ patients cannabis users (SCZ/c) as compared to healthy controls non-cannabis users (HC/nc). Moreover, we investigated quantitative and functional differences between HC/c and SCZ, and we characterized the distinct effect of cannabis in SCZ comparing SCZ/nc and SCZ/c.

Project description:Background. The growing popularity of cannabis smoking in an era of legalization has prompted concerns about respiratory health. Objective. To investigate clinical and airway epithelial transcriptomic features associated with cannabis smoking. Methods. This cross-sectional study analyzed 139 cannabis-smoking participants categorized by joint-year exposure (low: ≤5; moderate: >5-20; high: >20), and 57 never-smokers. We evaluated respiratory symptom questionnaire scores, lung function measurements, and chest computed tomography and hyperpolarized 129Xe pulmonary magnetic resonance imaging measurements across groups. We compared the expression of immune response signatures and mucin genes in airway epithelial brushings collected from bronchoscopy. Using air-liquid interface (ALI) cell cultures, we quantified epithelial MUC5AC protein and correlated its expression with clinical outcomes. Results. Among cannabis-smoking individuals (48% male and median age of 27 years), 84% reported current or former cigarette smoking or vaping. Cannabis-smoking groups reported worse respiratory symptoms than never-smokers. High joint-year cannabis-smoking participants showed lower pre-bronchodilator FEV1/FVC and FEF25-75, more radiographic emphysema, and more ventilation abnormalities than never-smokers. Airway epithelial brushings from cannabis-smoking individuals demonstrated increased type 2 immune response, decreased type 17 immune response, and higher MUC5AC gene expression than non-cannabis-smoking individuals. Epithelial MUC5AC protein expression in cell cultures correlated with worse clinical outcomes and imaging abnormalities. Conclusions. Cannabis smoking, particularly at high exposures, is associated with worse respiratory symptoms, lower lung function, functional imaging abnormalities, and dysregulated immune responses in the airway epithelium. These observations suggest respiratory harm associated with cannabis smoking and underscore the concerns for future respiratory morbidities related to persistent cannabis use.

Project description:Population-based studies show cannabis use doubles the risk of developing schizophrenia especially when use occurs in early adolescence (prior to age 15). However, the cause-and-effect mechanisms are largely unknown. To investigate the effect of cannabis on brain maturation and relation to the development of psychosis-like behaviours in adulthood, we treated young adolescent mice with vehicle or cannabis extract once a day for 2 weeks between postnatal days 14 and 28, and then collected hippocampal tissue for microarray analysis 12 weeks later. We identify a total of 78 differentially expressed genes (25 upregulated and 53 downregulated; p<0.05, fold change ± 1.2) and validate increases in dopamine D2 receptor (Drd2) and fatty acid amide hydrolase (Faah). Changes in Faah expression were limited to the hippocampus however Drd2 also increased in striatum but not prefrontal cortex or amygdala. When tested in adulthood with a behavioural panel relevant to schizophrenia, cannabis-treated mice displayed lower anxiety in the elevated zero-maze, decreased social preference, increased social novelty preference, mild cognitive impairments in a spatial version of the novel object recognition task and absence of latent inhibition when compared to vehicle controls. Adolescent treatment with cannabis extract thus lead to long-lasting changes in gene expression within the hippocampus which together result in behavioural deficits consistent with the negative and positive symptoms of schizophrenia.
