Valproic Acid

Valproic Acid: A medication commonly used to treat seizures, bipolar disorder, and migrains.
It works by increasing levels of gamma-aminobutyric acid (GABA) in the brain, which can help reduce neuronal excitability.
Valproic Acid is also being investigated for its potential neuroprotective and anti-inflammatory effects in various neurological conditions.

The following distinct sources of the SNIIRAM were used to select persons with depression:

Diagnoses of long-term or costly conditions (Affections de Longue Durée, ALD). Patients with specific long-term or costly conditions may require full coverage for all their condition-related health expenditures upon request by their family doctor and after approval by a health insurance fund medical officer (médecin-conseil) [18 ].

Data from national hospital claims (Programme de Médicalisation des Systèmes d’Information, PMSI) for all inpatient and day-case admissions in public and private general and psychiatric hospitals, containing medical diagnoses defined as ICD-10 codes. In both general and psychiatric hospitals, a principal diagnosis is defined as the main reason for admission, while associated diagnoses provide information about conditions that significantly influenced care during the hospital stay [19 ].

Data concerning all national health insurance reimbursements for drugs, laboratory tests and outpatient medical procedures. Individuals receiving reimbursements for antidepressants (N06A section of the ATC classification except for oxitriptan) can be identified. However, these databases do not contain direct information about the diagnosis justifying the prescription, and these drugs are not specific for depression, as they can also be prescribed for other conditions (bipolar disorders, anxiety or chronic pain). An antidepressant prescription is typically valid 1 month.

All three sources were not considered to be equally reliable for identifying patients with depression. Reliability of the sources was assessed as follows: for the purpose of identifying individuals suffering from depression, full coverage for depression as a specific long-term or costly condition (source 1) was more reliable than the hospital claims database (source 2), which was more reliable than reimbursement for antidepressants (source 3). In the hospital claims database, associated diagnoses reported during general hospital stays were assumed to be less reliable than those reported during psychiatric hospital stays. The reasons underlying this classification of source reliability included (1) the mode of acquisition of the information (diagnoses resulting from medical interviews were regarded as more reliable than hospital diagnostic codes sometimes coded by non-medical staff, themselves regarded as a more reliable diagnostic markers than prescription drugs) and (2) what was as stake when the information was coded (hospital diagnostic codes that had no consequence on costs were regarded as less reliable than codes influencing costs or giving access to benefits). These reasons are described and discussed more thoroughly in the Merits and drawbacks of the various methods section of the Discussion section of this article.
Accordingly, five estimation methods with decreasing order of reliability were defined. ICD-10 codes F32 to F39 were used in all estimation methods to identify depression (either as a full health coverage code or as a principal or associated diagnosis). At least three reimbursements for antidepressants were used to identify treatment by antidepressant. Hospital stays in the last 5 years with a principal or associated diagnosis of depression were used to identify principal diagnosis history and associated diagnosis history of depression respectively.

Method A (Full coverage for depression): Selection of individuals with full coverage for depression as a specific long-term or costly condition during the study (source 1);

Method B (Hospitalisation for depression): Selection of individuals with depression as principal or associated diagnosis in a psychiatric hospital stay or as principal diagnosis in a general hospital stay using two timeframes: (a) the current calendar year and (b) the last two calendar years (source 2). Calendar years were used for technical reasons.

Method C (Current antidepressant treatment + History of hospitalisation during the past 5 years): Selection of individuals treated by antidepressant and with a general hospital principal diagnosis history of depression or a psychiatric hospital principal or associated diagnosis history of depression (combination of sources 2 and 3);

Method D (Hospitalisation in a general hospital with an associated diagnosis of depression): Selection of individuals with depression as associated diagnosis in a general hospital stay using two timeframes: (a) the current calendar year and (b) the last two calendar years (source 2);

Method E (Current antidepressant treatment + History of hospitalisation in a general hospital with an associated diagnosis of depression during the past 5 years): Selection of individuals treated by antidepressant and with a general hospital associated diagnosis history of depression (combination of sources 2 and 3).

Individuals with a hospital diagnosis of bipolar disorder (ICD-10 codes F30 or F31) in the last 5 years or a specific treatment for bipolar disorder (lithium, divalproex or valpromide) were not included in the study.

The first dataset consists of nine gene perturbations with matched control samples (Almudevar et al., 2011 ); the second dataset is composed of two cell types and three treatments (Sampson et al., 2013 (link)); the third dataset is a study of the effect of p53 and/or Ras mutations on gene expression (McMurray et al., 2008 (link)).
In the first dataset, cells transformed to malignancy by mutant p53 and activated Ras are perturbed with the aim of restoring gene expression to levels found in non-transformed parental cells via retrovirus-mediated re-expression of corresponding cDNAs or shRNA-dependent stable knock-down. The data contain four to six replicates for each perturbation, and each perturbation has a corresponding control sample in which only the vector has been added (Almudevar et al., 2011 ).
The second dataset consists of two cell types—young adult mouse colon (YAMC) cells and mutant-p53/activated-Ras transformed YAMC cells—in combination with three treatments—untreated, sodium butyrate or valproic acid. Four replicates were performed for each cell-type/treatment combination (Sampson et al., 2013 (link)).
The third dataset is a comparison between four cell types—YAMC cells, mutant-p53 YAMC cells, activated-Ras YAMC cells and p53/Ras double mutant YAMC cells. Three replicates were performed for the untransformed YAMC cells, and four replicates were performed for each of the other cell types (McMurray et al., 2008 (link)).
As in the original publications, all three datasets were normalized to a reference gene, Becn1, with the resulting values denoted as ΔCt. In the first dataset, ΔΔCt values were computed by comparing each perturbed sample to its corresponding control sample. Additional details regarding each of these datasets can be found in the original publications.

Isolated crypts or single cells were cultured as previously described2 (link) with minimal modification. Briefly, crypts or single cells were entrapped in Matrigel and plated at the center of wells in a 24-well plate. Following polymerization of Matrigel (growth factor reduced; BD Bioscience), 500 μl of culture medium (Advanced DMEM/F12 (Life Technologies)) was added, containing growth factors including EGF (50 ng/ml, Life Technologies), Noggin (100 ng/ml, PeproTech) and R-spondin 1 (500 ng/ml, R&D) and small molecules including CHIR99021 (3 μM, Stemgent) and valproic acid (1 mM, Sigma-Aldrich). (See Supplementary Table 1 for details.) For comparison of different culture conditions, small molecules or growth factors were added to freshly isolated crypts immediately after plating in Matrigel to test the ability to minimize potential differentiation of the ISCs within the crypts and thus sustain crypt cultures. Cell culture medium was changed every other day. For single-cell culture, cells were embedded in Matrigel containing Jagged-1 peptide (1 μM; AnaSpec), and Y-27632 (10 μM; Tocris) was added for the first 2 d. Cells were passaged either as cell colonies as previously described2 (link) or as single cells. For single-cell passage, cell culture medium was removed and Accutase (Life Technologies) was added. After incubation at 37 °C for 10–20 min, cell colonies were dissociated into single cells by pipetting. Cells were then washed, embedded in fresh Matrigel and plated into 24-well plates. Cells cultured in the CV condition were passaged every 6 d at a 1:20 split ratio.

Mice were randomly assigned to each group. We used 2 classic anti-epilepsy drugs: carbamazepine (CBZ) and valproic acid (VPA). The treatments were initiated on day 10 after Dox withdrawal from the drinking water, the time-point at which the seizure activity began to become obvious. CBZ was dissolved in DMSO and diluted in 0.9% NaCl. VPA was directly added to the drinking water of both control and transgenic groups. The dosages were based on previous studies43 (link). For CBZ, we increased the dose daily to mimic the clinical application (Day 10: 5 mg/kg; Day 11: 10 mg/kg; Day 12: 15 mg/kg; Day 13: 20 mg/kg; Day 14: 25 mg/kg). For VPA, to reach 500 mg/kg per day, we decided the VPA concentration in the drinking water on the average daily volume of water consumed (around 5 mL per day).

BA and SCFA were quantified using HPLC-MS methods, as previously described.92 (link) Briefly, for BA analysis, plasma samples were placed in acetone (in the presence of seven deuterated internal standards) to allow for protein precipitation. Next, samples were centrifuged, supernatants were recovered and evaporated under a stream of nitrogen. Organic residues were then resuspended in methanol. Samples were analyzed using an LTQ-Orbitrap XL using an electrospray probe in negative mode. Chromatographic separation was achieved using an Ascentis Express C-18 column (4.6 × 100 mm, 2.7 µm) (Sigma-Aldrich) and a gradient of water and acetonitrile in the presence of formic acid. For SCFA analysis, the cecal content (50–60 mg wet material) was homogenized in water followed by sonication in an ice water bath. Acetonitrile was used for protein precipitation (in the presence of valproic acid as internal standard). Following centrifugation, the supernatant was recovered and a derivatization step (using 3-nitrophenylhydrazine in the presence of EDC and pyridine) performed. Samples were purified using liquid-liquid extraction to remove the remaining reagents. After evaporation, the final residue was analyzed using an LTQ Orbitrap XL mass spectrometer coupled to an Accela HPLC system (ThermoFisher Scientific). A Hypersil GOLD PFP (100 × 2.1 mm; 1.9 μm) column using a gradient of water-acetonitrile-acetic acid and acetonitrile-acetic acid allowed separating the different isomers. For ionization, an APCI probe was used in positive mode. For each cecal content, an aliquot was freeze-dried to determine a dry residue that was used for data normalization. For both types of analytes, calibration curves were prepared using the same conditions to determine sample content. Xcalibur® software was used for data analysis.

Sodium butyrate (B5887, Sigma-Aldrich) or valproic acid (P4543, Sigma-Aldrich) were dissolved in normal fly food medium at the final concentration of 10 mM. Three groups of flies were prepared: those treated with one of the HDAC inhibitors and those without HDAC inhibitor treatment (control flies). Adult flies aged 1 d were transferred to fly vials containing medium with or without a HDAC inhibitor. At the end of the fifth day of treatment, flies were collected, and their antennae were dissected for RNA extraction. All treatments and experiments were performed at room temperature. Two biological replicates with 60 flies/replicate were performed for each condition, with an average of 23 million reads / replicate, and with an average of 92% mapped. Multiplexed libraries were made from total RNA input using the Illumina TruSeq RNA sample preparation kit (v2) and 50 bps paired-end sequencing was done using the HighSeq2000.

D5_AR, 10E8v4, VRC01, PGDM1400, and 10-1074 IgG1s were expressed and purified from Expi293F cells. Expression vectors for D5_AR were generated previously (20 (link)), expression vectors for VRC01 and 10E8v4 were sourced from the NIH HIV Reagent Program (see “NIH HIV Reagents”), and expression vectors for 10-1074 were gifted from Dr. Christopher Barnes (28 (link), 48 (link)). PGDM1400 heavy and light chain sequences were synthesized (Integrated DNA Technologies) and cloned into a mammalian expression vector under a CMV promoter using InFusion (Takara) and sequence verified.
Expi293F cells were cultured in 33% Expi293 Expression/66% FreeStyle Expression medium (Thermo Fisher Scientific) and grown in baffled polycarbonate shaking flasks (Triforest) at 37 °C and 8% CO2. Cells were grown to a density of ~3 × 106/mL and transiently transfected using FectoPro transfection reagent (Polyplus). For transfections, 0.5 μg total DNA (1:1 heavy chain to light chain plasmids) was added per mL final transfection volume to culture medium (1/10 volume of final transfection) followed by FectoPro at a concentration of 1.3 μL per mL final transfection volume and incubated at room temperature for 10 min. Transfection mixtures were added to cells, which were then supplemented with d-glucose (4 g/L final concentration) and 2-propylpentanoic (valproic) acid (3 mM final concentration). Cells were harvested 3 to 5 d after transfection via centrifugation at 18,000 × g for 15 min. Cell culture supernatants were filtered using a 0.22-μm filter prior to purification.
Filtered Expi cell culture supernatants were buffered with 1/10 volume 10× PBS and loaded onto a HiTrap MabSelect SuRe column (Cytiva) equilibrated in PBS (pH 7.4) using a Cytiva ÄKTA Pure system at a flow rate of 3.5 mL/min. The column was subsequently equilibrated with five column volumes PBS (pH 7.4) before elution with three column volumes 100 mM glycine (pH 2.8) into 1/10th volume of 1M Tris (pH 8.0). The column was washed with 0.5 M NaOH with a minimum contact time of 15 min between purifications of different antibodies. Elutions were concentrated using Amicon spin filters (molecular weight cut-off 10 kDa; Millipore Sigma) and were subsequently loaded onto a GE Superdex S200 increase 10/300 GL column preequilibrated in 1× PBS using a Cytiva ÄKTA Pure system. Protein-containing fractions were identified by A280 signal and/or SDS-PAGE, pooled, and stored at 4 °C or at −20 °C in 10% glycerol/1× PBS until use.
