PR:PROJECT_TITLE                 	Human primary astrocytes finger- and footprinting metabolomics indicate
PR:PROJECT_TITLE                 	biochemical alterations under ayahuasca treatment
PR:PROJECT_TYPE                  	Untargetmetabomics- hilic
PR:PROJECT_SUMMARY               	Ayahuasca (Aya) is a psychotropic Amazonian beverage formulated from the
PR:PROJECT_SUMMARY               	combination of the Banisteriopsis caapi vine and the Psychotria viridis leaves
PR:PROJECT_SUMMARY               	in a water decoction. Aya is legally used in Latin American countries and used
PR:PROJECT_SUMMARY               	in Brazil for religious, cultural, and therapeutic purposes. Its properties
PR:PROJECT_SUMMARY               	constitute a bio-psycho-social-spiritual model involving effects from
PR:PROJECT_SUMMARY               	ß-carboline-derived alkaloids, present in the vine, and N,N-dimethyltryptamine
PR:PROJECT_SUMMARY               	(DMT), a tryptamine-derived alkaloid present in the leaves, which act together
PR:PROJECT_SUMMARY               	in the central nervous system (CNS). Few technical-scientific studies have been
PR:PROJECT_SUMMARY               	conducted to understand the effects of this brew in the metabolism. Therefore,
PR:PROJECT_SUMMARY               	this work aims to investigate an in vitro primary astrocyte lineage model by
PR:PROJECT_SUMMARY               	untargeted metabolomics evaluations of two cellular subfractions: secretome and
PR:PROJECT_SUMMARY               	intracellular content after Aya treatment, where DMT and other ß-carbolines
PR:PROJECT_SUMMARY               	were previously quantified. Metabolomics analysis was performed by UHPLC-MS/MS,
PR:PROJECT_SUMMARY               	followed by MS-Dial data processing and statistical analysis to identify
PR:PROJECT_SUMMARY               	metabolites and biochemical alterations related to Aya treatment. Aya doses were
PR:PROJECT_SUMMARY               	applied to the cell cultures considering DMT concentrations of 1, 10 and 20 µM,
PR:PROJECT_SUMMARY               	which are in agreement with non-toxic and toxic DMT threshold assays in primary

#TREATMENT
TR:TREATMENT_SUMMARY             	Aya doses were applied to the cell cultures considering DMT concentrations of 1,
TR:TREATMENT_SUMMARY             	10 and 20 µM, which are in agreement with non-toxic and toxic DMT threshold
TR:TREATMENT_SUMMARY             	assays in primary human astrocyte cells viability.secretome (extracellular
TR:TREATMENT_SUMMARY             	fraction) were collected, centrifuged under 500 x g at room temperature (about
TR:TREATMENT_SUMMARY             	27 ºC) for 5 min, stored and conditioned at -80 °C until the time of
TR:TREATMENT_SUMMARY             	metabolomics sample preparation. In parallel, to obtain the content of
TR:TREATMENT_SUMMARY             	intracellular metabolites, cell monolayers were washed three times with 5 mL of
TR:TREATMENT_SUMMARY             	ice-cold PBS to remove any excess of secretome. Subsequently, a mechanical
TR:TREATMENT_SUMMARY             	detachment was performed for removal, followed by chemical rupture of the cell
TR:TREATMENT_SUMMARY             	wall in 1.2 mL of ice-cold 80 % (v/v) methanol in PBS solution, to obtain an
TR:TREATMENT_SUMMARY             	intracellular metabolite suspension. The intracellular fractions, in methanol
TR:TREATMENT_SUMMARY             	solution, were stored and conditioned at -80 °C.
#SAMPLEPREP
SP:SAMPLEPREP_SUMMARY            	For metabolomics analysis, after being defrosted, the secretome samples volumes
SP:SAMPLEPREP_SUMMARY            	were reduced to 500 μL by centrifugation in an Amicon® Ultra-2 mL (Millipore)
SP:SAMPLEPREP_SUMMARY            	filter, according to the manufacturer specifications. Then, quality control (QC)
SP:SAMPLEPREP_SUMMARY            	samples were prepared previously to the protein precipitation. Ice-cold 80 %
SP:SAMPLEPREP_SUMMARY            	(v/v) methanol was added to the concentrated secretome, kept at -80 °C, as well
SP:SAMPLEPREP_SUMMARY            	as the intracellular fraction, for the protein precipitation step for 24 h.
SP:SAMPLEPREP_SUMMARY            	After that period of time, all samples (extra and intracellular metabolite
SP:SAMPLEPREP_SUMMARY            	suspensions) were centrifuged at 16,000 x g at 4 °C for 15 min, the
SP:SAMPLEPREP_SUMMARY            	supernatants filtered in a 0.22 μm syringe filter, and dried in a vacuum
SP:SAMPLEPREP_SUMMARY            	concentrator. For each cellular fraction, 12 samples were included in the
SP:SAMPLEPREP_SUMMARY            	analysis, where three (3) experimental samples for each group were identified as
SP:SAMPLEPREP_SUMMARY            	Aya0, Aya1, Aya10, or Aya20, corresponding to DMT doses in µmol L-1, and five
SP:SAMPLEPREP_SUMMARY            	(5) for QC samples, being four (4) QC related to dose-treatments and one (1) to
SP:SAMPLEPREP_SUMMARY            	all treatment groups.

MS:MS_COMMENTS                   	Detection was performed using a XEVO-G2XS quadrupole time-of-flight (QTOF) mass
MS:MS_COMMENTS                   	spectrometer (Waters Corp., Manchester, UK) equipped with an electrospray
MS:MS_COMMENTS                   	ionization (ESI) source. Data were collected in both positive and negative
MS:MS_COMMENTS                   	ionization modes, separately. The acquisition was performed using
MS:MS_COMMENTS                   	data-independent analysis (MSE), with the following parameters: capillary
MS:MS_COMMENTS                   	voltage +3.5 kV (positive mode) and -2.5 kV (negative mode), sample cone voltage
MS:MS_COMMENTS                   	at 40 kV, source temperature at 140 °C, desolvation temperature of 550 °C,
MS:MS_COMMENTS                   	desolvation gas flow of 900 L h−1, and cone gas flow of 10 L h−1 (positive
MS:MS_COMMENTS                   	mode) or 50 L h−1 (negative mode). MS data were acquired in the centroid mode
MS:MS_COMMENTS                   	from m/z range of 50–1200 Da, using the acquisition rate of 0.5 s per scan.
MS:MS_COMMENTS                   	The MSE analysis was operated at 20 V for low collision energy and 50 V for high
MS:MS_COMMENTS                   	collision energy. During MS analysis, a leucine enkephalin (Waters®, molecular
MS:MS_COMMENTS                   	mass = 555.62; 200 pg μL-1 in 1:1 ACN: H2O) was continuously infused into MS at
MS:MS_COMMENTS                   	a flow rate of 30 µL min-1 and the ions [M-H]- = 554.26 and [M+H]+ = 556.27
MS:MS_COMMENTS                   	were used as lock mass for accurate mass measurement. Data acquisition was
MS:MS_COMMENTS                   	controlled by MassLynx V4.2 (Waters®). Calibration was performed prior to
MS:MS_COMMENTS                   	sample analysis via infusion of 0.5 mmol L-1 sodium formate solution, which was
MS:MS_COMMENTS                   	used for calibration procedures, both in positive and negative mode analysis.
MS:MS_COMMENTS                   	Samples were randomly analyzed and QC samples composed of pooled samples after
MS:MS_COMMENTS                   	resuspension were injected every 8 injections. Data processing and metabolite
MS:MS_COMMENTS                   	identification. All MSE datasets were converted from the vendor-specific file
MS:MS_COMMENTS                   	format (.raw) into the Analysis Base File format (.abf) using the freely
MS:MS_COMMENTS                   	available Reifycs ABF converter
MS:MS_COMMENTS                   	(https://www.reifycs.com/AbfConverter/index.html). After conversion, the MS-DIAL
MS:MS_COMMENTS                   	software (version 5.0) was used for feature detection, spectral deconvolution,
MS:MS_COMMENTS                   	peak identification, and alignment between samples. MassBank databases were used
MS:MS_COMMENTS                   	for identification from MS-DIAL metabolomics MSP spectral kit containing ESI-MS
MS:MS_COMMENTS                   	and MS/MS (positive; 8,068 and negative; 4,782 compounds).
MS:MS_COMMENTS                   	(http://prime.psc.riken.jp/compms/msdial/main.html). The parameters for MS-DIAL
MS:MS_COMMENTS                   	were optimized based on their based on developer instructions. The UHPLC-MS raw
MS:MS_COMMENTS                   	data were processed with MS-DIAL version 4.8 [30]. Automatic feature detection
MS:MS_COMMENTS                   	was performed between 0.3 and 13 min for mass signal extraction between 100 and
MS:MS_COMMENTS                   	1500 Da in positive and negative modes. MS1 and MS2 tolerance were set to 0.01
MS:MS_COMMENTS                   	and 0.4 Da, respectively, in profile mode. For identification, it was used the
MS:MS_COMMENTS                   	default of accurate mass tolerance 0.01 Da for MS1 and 0.05 Da for MS2, and
MS:MS_COMMENTS                   	identification score cut off 80 %. For the potential adducts, [M+H]+, [M+Na]+,
MS:MS_COMMENTS                   	[M+K]+, [M+NH4]+, [2M+H]+, [M+2H]2+, [M+2Na]2+, [M+2K]2+, [M+H+Na]2+, [M+H+K]2+,
MS:MS_COMMENTS                   	[M+H+NH4]2+, [M+2Na-H]+, [M+2K-H]+, [M+H-H2O]+, and [M+H-2H2O]+ were considered
MS:MS_COMMENTS                   	for positively charged adducts, while [M-H]-, [M+Cl]-, [M-H-H2O]-, [2M-H]-,
MS:MS_COMMENTS                   	[M-2H]2-, [M+Na-2H]-, [M+K-2H]-, and [M+FA-H]- were considered for negatively
MS:MS_COMMENTS                   	charged. To generate matrix files for downstream statistical analysis, the
MS:MS_COMMENTS                   	aligned results were exported by selecting the area raw data matrix, that were
MS:MS_COMMENTS                   	restructured by applying a manual exclusion filter for unknown metabolites, and
MS:MS_COMMENTS                   	the negative and positive files were combined for statistical analysis in
MS:MS_COMMENTS                   	MetaboAnalyst 5.0 [31].
