Acetylcysteine

Acetylcysteine is a mucolytic agent and antioxidant used to treat a variety of respiratory conditions and for acetaminophen overdose.
It helps thin out and loosen mucus, making it easier to cough up.
Acetylcysteine also has antioxidant properties that can protect cells from damage.
It is commonly used to treat chronic bronchitis, COPD, and to prevent kidney damage from acetaminophen poisoning.

The adult brain slice method we have described has been successfully implemented in a variety of experimental contexts for analysis of diverse brain regions and cell types. However, we would encourage adopters to view this method as a work in progress, and we believe there is still substantial room for systematic improvement. As a case in point, we have observed that mature adult brain slices experience high levels of oxidative stress due in large part to rapid depletion of cellular antioxidants including ascorbate and reduced glutathione (GSH). This can lead to lipid peroxidation, neuronal membrane rigidity, and tissue deterioration. There appears to be a nonuniform susceptibility to this form of oxidative damage, for example, CA1 and CA3 pyramidal neurons are particularly vulnerable, making patch clamp recording of these cells difficult in brain slices from adult and aging animals in spite of the protective recovery method.
The specific restoration of intracellular pools of neuronal GSH (e.g. supplementation with the cell-permeable GSH-ethyl ester) is highly effective at curbing deterioration and prolonging slice viability under these circumstances. Thus, we have been able to further improve the NMDG recovery method by devising strategies for stimulating de novo synthesis of glutathione during acute brain slice preparation and incubation. This is most readily accomplished by adding the inexpensive GSH precursor N-acetyl-L-cysteine (NAC, 5–12 mM) to the NMDG aCSF and HEPES holding aCSF formulas, but not the recording aCSF (seeNote 14). NAC is cell-permeable and has been shown to specifically increase neuronal glutathione levels in brain tissue (26 (link)). Within 1–2 hours of slice preparation we are able to observe notable improvements in the general appearance of neurons and in the ease of patch clamp recording, and the slices are able to be maintained in a healthy state for extended time periods.
Although these more advanced methods are not absolutely required for successful adult brain slice patch clamp recordings (as demonstrated by the specific application we have described in this chapter), we include this information in hopes of providing more options to extend the versatility of our method for particularly challenging applications. Glutathione restoration is highly effective at maintaining healthy brain slices but may not be appropriate in every experimental context, e.g. investigations focusing on oxidative stress in the aging brain. On the other hand, without implementing the NMDG protective recovery method together with glutathione restoration strategy, targeted patch clamp analysis in brain slices from very old animals is prohibitively challenging.

Described previously 2 (link), 4 (link). For culture/sorting experiments, at least 3 independent experiments were performed. For each experiment, crypts/cells were pooled from 3 intestines. For microarray, sorted cells from 10 intestines were pooled. Crypts were directly cultured as previously described (100 crypts/well on 24-well plate) 4 (link). For single-cell or doublet-cell culture, crypts were dissociated with TrypLE express (Invitrogen) including 2000 U/ml DNase (Sigma) for 30 min at 37 °C or 2 hr at room temperature. For reassociation assay from established crypt organoids, the samples were dissociated with TrypLE express for 15 min at 37 °C. Dissociated cells were passed through 20- μm cell strainer (Celltrix) and washed with PBS. Cells were stained with PE- conjugated anti-CD24 antibody (eBioscience) and APC- conjugated anti-Epcam antibody (eBioscience) for 15 min at 4 °C, and analyzed by MoFlo (DakoCytomation). Viable epithelial single-cells or doublets were gated by forward scatter, side scatter and pulse-width parameter, and negative staining for propidium iodide or 7-ADD (eBioscience). Sorted cells were collected, pelleted, and embedded in Matrigel (BD bioscience), followed by seeding on 96-well plate (30-50 singlets or doublets/10 μl Matrigel/well.

The evaluation of the response to treatments will be performed when PDTO have reached a diameter of 150 μm in « PDTO treatment medium », corresponding to the PDTO culture medium lacking N-Acetylcysteine, Y-27632 and primocin.
PDTO will be collected, resuspended in 2% extracellular matrix/PDTO culture medium and then platted in white and clear bottom 96-well plates previously coated with a 1:1 volume mix of PDTO treatment medium with extracellular matrix. In the case of evaluation of the response to radiotherapy, PDTO will be before irradiated using the CellRad System (FAXITRON Bioptics). In the case of evaluation of the response to chemotherapy or PARP inhibitors, drugs are prepared in 2% extracellular matrix/PDTO culture medium and added 1 hour after PDTO have been plated.
In the case of evaluation of the response to immunotherapies, PDTO will be co-cultured with PDTO specific T cells previously generated (see co-culture of PDTO with immune cells) at a 5:1 ratio. Treatments (such as Nivolumab or Pembrolizumab) will be added directly in the co-culture. A condition containing an MHC-I blocking antibody will be added to control for antigen specific killing.
PDTO morphology will be monitored by taking images during the required time using Incucyte S3 (Sartorius). At the endpoint, PDTO response will be assessed using CellTiter-Glo 3D cell viability assay (Promega) according to the manufacturer’s instruction and luminescence will be measured using GloMax Discover GM3000 (Promega) with the associated software. Results will be normalized to the control condition. IC50 will be calculated with GraphPad software. The ability of T cells to recognize and induce lysis of PDTO will be monitored via analysis of caspase 3 cleavage within PDTO and visualization of LAMP-1 on the membrane of CD8+ T cells.
The treatment response of the PDTO will be finally compared to the clinical response (PFS/DFS/OS) of the patient from whom they are derived in order to validate the predictive value of this model for HNSCC.

Crypts were isolated from the small intestine of mice fed with SD or CDAHFD for 3 wk as previously described17 (link). Briefly, the ileum segments were shaken in cold HBSS containing 30 mM EDTA. After vigorous shaking for ~ 300 times in HBSS, the isolated crypts were resuspended in HBSS containing 300 U/mL collagenase (Sigma), 10 µM Y-27632 (Sigma), and 1 mM N-acetylcysteine (Sigma), and shaken at 180 rpm for 5 min at 37 °C on a horizontal shaker (TAITEC). Then, 50 μg/μL Dnase I (Roche) was added, and the sample was mixed by pipetting. Cells were pelleted at 500 g for 5 min at 4 °C and resuspended in washing buffer (DMEM/F12 containing 10 μM Y-27632 and 1 mM N-acetylcysteine), then passed through 40-μm cell strainer (BD Falcon). Paneth cells were stained with Zinpyr-1 (Santa Cruz) and Allophycocyanin (APC) anti-CD24 (clone M1/69,)Abcam) in washing buffer for 10 min at 37 °C. After Paneth cell labeling, the cells were sorted by flow cytometry using a cell sorter (JSAN, Bay Bioscience). Single cells were gated by forward scatter and side scatter. Cells were sorted directly into lysis buffer for RNA isolation (PureLink RNA Mini Kit, Invitrogen). To make a pooled sample, at least 10,000 Paneth cells were sorted from 2 separate mice, and sorting experiment was repeated three times. 2 pools (each pool contains Paneth cells from 6 separate mice) were prepared for each group. Total RNA was isolated using Invitrogen® PureLink RNA Purification System according to manufacturer’s instructions, and cDNA was synthesized using a SMART-Seq. Sequencing libraries were built with the TruSeq RNA Library Prep Kit (Illumina) and then submitted to Illumina NovaSeq 6000 for 100-bp PE reads sequencing. Fragments per kilobase of transcript per million mapped reads (FPKM) values were used, genes with FPKM values below 1 were not included in the analysis, and fold change ≥ 1.5 or ≤ 0.67 was considered differentially expressed.
