The X. laevis H3C110A mutant (xH3C110A) was used to mimic the yeast histone dimerization surface and to avoid any unwanted cysteine / dye reaction (46 (link)). X. laevis histone H4T71C mutant (xH4T71C) was fluorescently labeled (26 (link),46 (link)) (Supplementary Figure S1) with the Qsy9 fluorescence quencher or fluorescein (FM) (Invitrogen) as previously described (46 (link)). The xH3C110A and Qsy9 or FM labeled xH4T71C were then prepared as tetramers yielding either H3/H4*Q or H3/H4*FM. yAsf1 was labeled with Alexa Fluor 532 (Invitrogen) yielding yAsf1*. The position of the labeled cysteine is shown in Supplementary Figure S1, while the other two cysteines in yAsf1 (Cys30 and Cys99) are not near the histone-binding interface and are not labeled efficiently in this procedure (as verified by mass spectrometry, data not shown). Measurements were performed at a yAsf1 concentration of 1 nM in buffer [10 mM Tris-HCl (pH 7.5), 150 mM KCl, 2 mM MgCl2, 1% glycerol and 0.05% Brij-35]. Double measurements were made with an integration time of 0.5 s on a Horiba Fluorolog-3 spectrometer at 20°C, using a 0.5 cm path-length cuvette. The excitation wavelength was 528 nm, with a slit width of 7 mm; emission was recorded at 547 nm with a slit width of 7 mm. H3/H4 labeled with Qsy9 was titrated to the cuvette containing yAsf1* and the decrease of yAsf1* fluorescence was monitored. Control samples with buffer or unlabeled histones were analyzed likewise to discount buffer effects on fluorescence. The buffer was scanned in the same range used in all experiments for background contributions to the readings and was corrected for in each spectrum. Varying incubation times (0–30 min) confirmed that the fluorescence signal had reached equilibrium by 5 min. The reactions were allowed to equilibrate at 20°C for at least 5 min prior to measurement, and at least three independent experiments were performed for each sample. Data were fitted with the ligand-depleted binding model [Equation (1 (link))] in cases where the concentration of yAsf1* was within 10-fold of the Kd value.

with the variable i indicating the varying concentrations of H3/H4 that were titrated into the yAsf1*.

Urea reagents were prepared as described in Jung et al. (1975) (link). The final Jung working reagent consisted of 100 mg/L o-phthalaldehyde, 215 mg/L N-(1-naphthyl)ethylenediamine, 2.5 mol/L sulfuric acid, 2.5 g/L boric acid, and 0.03% Brij-35. The modified reagent used 513 mg/L primaquine bisphosphate in place of the 215 mg/L N-(1-naphthyl)ethylenediamine reagent. The urea standard was prepared in double-distilled water and contained 5.00 mg/dL urea. To perform the assay, 50 μL of water, 50 μL of the 5.00 mg/dL standard, and 50 μL samples were transferred into separate wells of a clear flat-bottom 96-well plate. Then to each well, 200 μL of freshly prepared working reagent was added and mixed quickly by gently rocking the plate. The reaction was incubated for 1 h at room temperature. Optical densities (OD) at 430 and 505 nm were measured on the plate reader for assays using the modified reagent and the original Jung reagent, respectively.
The calibration curve (Fig. 1A) shows that the assay is linear between 0.00 and 5.00 mg/dL urea. For calculation of the sample urea concentration, the experimenter can choose either to use the slope of the standard curve or to use a single urea concentration (see below). We found that it is sufficient to use one blank (water) and one single urea concentration (5.00 mg/dL) to calculate the sample urea concentrations. In this work, urea concentration in the sample was calculated from the OD values:
[Urea]=ODSAMPLEODBLANKODSTANDARDODBLANK×n×[Standard](mg/dL) where ODSAMPLE, ODSTANDARD, and ODBLANK are OD430 nm values of the sample, standard, and water blank, respectively. [Standard] is the concentration of the urea standard (5.00 mg/dL or 0.83 mmol/L) and n is the dilution factor. Dilution of samples in distilled water is necessary when sample OD430 nm values are higher than the OD430 nm value for the 5.00 mg/dL urea standard.

Immunohistochemistry was performed with the indirect enzyme-labelled antibody method, as described previously [1 (link), 17 (link), 27 (link)]. For the detection of histone H3, H3K4me3, H3K9ac, H3K18, H3K23ac, H3K27me3, and H3S10phos, paraffin sections of mouse testis were deparaffinized with toluene and dehydrated in serially graded ethanol solutions. The sections were autoclaved in a 10 mM citrate buffer (pH 6.0) for 15 min at 120°C. Then, the sections were preincubated with 500 µg/ml normal goat IgG dissolved in 1% BSA in PBS, pH 7.4, for 1 hr. Unless otherwise specified, all reactions were conducted at room temperature. Then the sections were reacted 16 hr with first antibodies in 1% BSA in PBS. After incubation, the sections were washed with 0.075% Brij 35 in PBS three times for 15 min each. The sections were then incubated with HRP-conjugated goat anti-rabbit IgG in 1% BSA in PBS for 1 hr. After washing with 0.075% Brij 35 in PBS three times for 15 min each, the sites of HRP were visualized with DAB and H2O2 in the presence of nickel and cobalt ions [4 ]. As a negative control, some sections were reacted with normal rabbit IgG instead of the specific antibodies.

Gelatin zymography was performed to assess MMP-9 and -2 activity following treatment of THP-1 cells with DTG, CAB, BIC, or DOX. This assay was used as preliminary confirmation of the inhibition of MMPs by individual INSTIs. Due to the nature of this assay, only the gelatinases, MMP-2 and -9, could be assessed. Cells were plated at a density of 1 × 106 in 12 well plates and treated with phorbol-12-myristate-13-acetate (PMA) for 24 h. This was done to promote cell differentiation to stimulate MMP secretion. Following PMA treatment, cells were treated with DTG, CAB, BIC, or DOX at concentrations of 25, 50, 75, or 100 µM or control vehicle for 24 h. In our previous study, no DTG-induced cytotoxicity was recorded in PMA-stimulated THP-1 cells up to 100 µM (Bade et al., 2021 (link)). Thus, for comparative assessments among different INSTIs (DTG, BIC, and CAB) and DOX (positive control) drug concentrations of up to 100 µM were utilized. Each of the experimental tests were performed in triplicate. Following treatment, media was collected and centrifuged at 15,000 x g for 10 min at 4°C. Supernatant was collected and stored at −80°C for further analysis. For gelatin zymography, 3 µg of protein from cell medium was loaded in a 10% SDS-polyacrylamide gel containing 0.1% gelatin. Gels were ran at 55 V until the loading dye passed through its bottom. The gel was then removed and washed with water for 15 min, then incubated with renaturation buffer [2.5% (v/v) Triton X-100 in Milli-Q water] for 90 min at room temperature. The used renaturation buffer was replaced with fresh buffer every 30 min. Renaturation buffer was then replaced with developing buffer (50 mM Tris–HCl, pH 7.5, 5 mM CaCl2, 0.2 M NaCl, and 0.02% Brij-35) and the gel was incubated at 37°C in a shaker (Innova 42, New Brunswick Scientifc, Edison, NJ) for 48 h. After 48 h, the gel was washed with water for 15 min and then stained using 0.2% Coomassie Brilliant Blue R-250 (BIO-RAD, Hercules, CA) for 1 h. After staining, the gel was washed with water for 15 min before washing with destaining solution (30% methanol, 10% acetic acid, 60% water) for 45 min. The gel was then washed with water for 20 min to remove any destaining solution. Finally, the stained gel was imaged using the iBright 750 Imaging System (Invitrogen, Carlsbad, CA). ImageJ software was used to quantitate band density recorded as a measure of relative MMP activity.

β-1,3-glucan synthase activity was measured referring to the method of Belewa et al. (2017) (link). Microsomal proteins were obtained by crushing mycelia and pulverizing by ultracentrifugation. The microsomal proteins were resuspended in 500 μl buffer (1 mmol/l EDTA; 1 mmol/l DTT; 33% (v/v) glycerol; 50 mmol/l Tris–HCl, pH 7.5) and stored at −80°C until use. A 50 μl reaction system was established consisting of 50 mmol/l Tris–HCl (pH 7.5), 20 μmol/l GTP, 4 mmol/l EDTA, 0.5% Brij-35, 6.6% glycerol, 2 mmol/l UDP-Glc, and 100 μg microsomal protein. After incubation at 25°C for 30 min, the reaction was stopped by adding 10 μl of 6 mol/l NaOH. The dextran produced by the previous process was dissolved at 80°C for 30 min. The glucan content was measured by the aniline blue method. One unit of enzymatic activity (U/mg protein) is defined as 1 mg protein catalyzed to produce 1 μg of glucan.

Fresh brain tissues were immersed in RIPA lysis buffer (P0013K, Beyotime, China) at a ratio of 1:4 (w: v) and centrifuged at 4°C (12,000 rpm, 15 min) after homogenization. The protein concentration was determined by a BCA concentration determination kit (P0010, Beyotime, China). The supernatant and loading buffer (P0016N, Beyotime, China) were mixed at a ratio of 4:1. A total of 120 μg of total protein was loaded into an 8% SDS‒PAGE gel containing 10% gelatin. After electrophoresis at 80 V in ice water for 3 h, each gel was washed in 2.5% Triton X-100 for 30 min 3 times. Then, gels were treated with incubation buffer (50 mM Tris-HCL, 0.2 M NaCl, 5 mM CaCl2, 1 µM ZnCl2, 0.02% Brij-35, pH 7.5) for 48 h at 37°C on a shaking table. Gels were stained with 0.5% Coomassie brilliant blue R250 (ST1123, Beyotime, China) for 3 h and then dyed with 30% methanol containing 10% acetic acid until the emergence of an appropriate color discrepancy. The clear bands on the zymogram represented gelatinase activity.
