Cell viability was determined by the MTT-based assay using Cell Proliferation Reagent WST-1 (Roche, Basel, Switzerland) according to the manufacturer’s instruction. Cells (5000 cells/well) were plated in 96-well culture plates, and various concentrations of (-)-gossypol or docetaxel were added to the cells in triplicates. Four days later, WST-1 was added to each well and incubated for 1.5 hours at 37°C. Absorbance was measured with a plate reader at 450 nm with correction at 650 nm. The results are expressed as the % of absorbance of treated wells versus that of vehicle control. IC50, the drug concentration causing 50% growth inhibition, was calculated via sigmoid curve fitting using GraphPad Prism 5.0 (GraphPad, Inc.).

Animal experiments were performed following a protocol (NCU202019BM) reviewed and approved by the Institutional Animal Care and Use Committee of Jiangxi Provincial People’s Hospital. The in vivo effects of depletion of NCOA3-p300-NF-κB members were determined by mixing 5.0 × 105 Control-KD1, RelA-KD1, NFKB1-KD1, p300-KD1, and NCOA3-KD1 cells (all in T47D background) in 100 μL of PBS with 50% Matrigel (Sigma-Aldrich; #CLS354234) and inoculating them subcutaneously into one armpit of female BALB/c nude mice (22–25 g) (n = 10 for each group) (Vital River Laboratories, Beijing, China). Each group of mice was randomly divided into two subgroups. One mouse subgroup was implanted with a 0.18 mg E2 pellet (Innovative Research Of America, Sarasota, FL, USA; #NC1775204) following a previous protocol [21 (link)]. The other group underwent the same surgery but without E2 pellet implantation. The position of the E2 pellet implantation was contralateral to the cell injection site between the skin and the peritoneal wall. Tumor sizes were measured every 5 days with a digital caliper (Thermo Fisher; #0666416), and tumor volumes were calculated using the formula: volumes = ½ (Length × Width2). For evaluation of the in vivo effects of NCOA3 inhibitors, T47D cells (5.0 × 105) were injected into female BALB/c nude mice (n = 60), and half of the mice were further implanted with a 0.18 mg E2 pellet. After the tumor volumes reached approximately 150 mm3, the mice were randomly grouped and injected intraperitoneally every 5 days with 1.5 mg/kg bufalin (n = 10), 50 mg/kg gossypol (n = 10), or PBS (control, n = 10). Tumor sizes were measured with a digital caliper every 5 days.

Using FM (crude protein, 73.6%) and CSM (crude protein, 49.6%; free gossypol, 1.12 mg/g) as the primary protein sources, five isonitrogenous (41% crude protein) and isocaloric (21 kJ/g gross energy) diets (C0, C8.5, C17.2, C25.7, and C34.4) were prepared to replace 0%, 12%, 24%, 36%, and 48% FM protein with 0%, 8.5%, 17.2%, 25.7%, and 34.4% CSM, respectively. DL-methionine, L-lysine, and L-leucine were also supplemented to each diet to provide equal amounts of methionine, lysine, and leucine in all experimental diets. The feed ingredients and proximate composition of experimental diets are listed in Table 1, and the corresponding amino acid profiles are shown in Table 2.
All feed ingredients except lipid sources were crushed and passed through a sieve with a diameter of 320 μm. Soybean lecithin was preblended in the mixture of soybean oil and fish oil. All ingredients were thoroughly mixed; the lipid mixture was added, and then thoroughly mixed again. Suitable water was added to make a dough, and the dough was squeezed into 1.5-mm pellet by a pellet feed maker (KS-180; Jiangsu Jingu Rice Mill Co., Ltd., Zhenjiang, China). The wet pellets were dried at 40°C and then stored at −20°C until use.

The proximate composition of feed ingredients, experimental diets, and whole-body samples were measured following the method of AOAC [22 ]. Dry matter was determined by drying the sample to a constant weight at 105°C; crude protein content was examined by the Kjeldahl method (N × 6.25); crude lipid content was determined using the Soxhlet method with ether extraction; crude ash content was determined after burning in a muffle furnace at 550°C for 6 h. A bomb calorimeter (Parr 1351; Parr Instrument Co., Moline, IL, USA) was used to measure gross energy. Free gossypol content in diets was determined by high-performance liquid chromatography [23 (link)]. The amino acid composition of diets was determined using the method described by Mai et al. [24 (link)].

The online tool SGN VIGS (https://vigs.solgenomics.net/) was used to design the appropriate silencing region in the target gene [36 (link)]. The parameters were set as follows: n-mer size is 21, fragment length is 300, and mismatches is 0. The specific parameters could be adjusted according to the score. DNAMAN8 was used for restriction enzyme analysis, the target fragment was ligated to TRV2 (tobacco rattle virus) vector through EcoRI and BamHI digestion sites, and the recombinant vector was constructed into the competent cells of Agrobacterium tumefaciens GV3101 by freeze–thaw method. The bacterium GV3101 containing pTRV1 vector was used as auxiliary bacteria, TRV1/GV3101 and TRV2/GV3101 were mixed in a 1:1 ratio and injected into the cotyledons of 8-day-old cotton seedlings until the leaves were filled and incubated in the dark for 24 h, at least 30 cotton seedlings were injected for each gene. After 30 days, the leaves were harvested to measure the gossypol content.
