The M. bovis strain used was a first passage level culture isolated from a naturally infected wild boar in Coletsos medium. The isolate was propagated in Middlebrook 7H9 broth enriched with OADC for 2–3 weeks. Cells were harvested by centrifugation at 2500 x g for 20 minutes and washed twice in PBS. The bacterial pellet was re-suspended in PBS and declumped using a fine needle syringe. The turbidity of this suspension was adjusted to an optical density of 1 McFarland unit. Before inactivation, tenfold serial dilutions were prepared and plated in agar-solidified 7H9 with OADC in quadruplicate to assess the number of cfu in the inoculum. The inoculum was then inactivated in a water bath at 80°C for 30 minutes. Animals in “parenteral inactivated vaccine” and “oral inactivated vaccine” groups were administered with approximately 6×106 bacteria according to cfu counts. The parenteral vaccine (1 ml) was prepared using Montanide ISA 50 V, an oily adjuvant of mannide oleate and mineral oil (Seppic, Castres, France). The oral vaccine consisted of 2 ml of PBS containing the inactivated mycobacteria. This inactivated vaccine was again cultured in duplicate to assure absence of viable M. bovis.

Stock solutions of sodium palmitate (SP) and oleate (OA) (Sigma-Aldrich, United States) were prepared, as previously described (Römer et al., 2021 (link); Cao et al., 2012 (link)). Briefly, 100 μM of SP and OA were incubated for 30 min at 50 °C. Later, fatty acids were mixed with BSA in a culture medium (the fatty acid to BSA molar ratio was 4:1). To induce steatosis, HepG2 and Huh7 cells were exposed to SP and OA conjugated with fatty acid-free BSA. After incubation for 24 h, the cells were treated for 24 h with various concentrations of withaferin A (1, 2.5, and 5 μM). Cells used as controls were treated with fatty acid-free media containing ethanol as a vehicle.

Lipase hydrolytic activity was assessed by monitoring the conversion of 4-methylumbelliferyl oleate (4-MUO) into 4-methylumbelliferone (4-MU). The enzymatic activity was determined by measuring the 4-MU fluorescence signal at 460 nm (after excitation at 355 nm) over time. A commercial reference inhibitor, orlistat, was used as the positive control, and citrate-phosphate buffer (0.1 M, pH 7.4) was used as the reaction buffer. A series of 4-MU dilutions in buffer was used to generate the standard curve to convert absorbance values into 4-MU concentrations. A 4 g/L solution of lipase in buffer was centrifuged at 5000× g and 10 °C for 10 min, then the supernatant was aliquoted. The final on-well concentration used in the assay was 250 mg/L. In each microplate well, 20 µL of test products diluted in a 10:90 (v:v) DMSO:water mixture (or 20 µL of this solvent mixture for the controls), 20 µL of lipase in buffer (or 20 µL of buffer for the blanks), and 110 µL of buffer were incubated at 37 °C in a microplate reader for 10 min. Then, 10 µL of 4-MUO substrate (48 µM in DMSO) was added to each well to initiate the reaction. Fluorescence was measured at 355 nm/460 nm (excitation/emission) using a FLUO Star Omega (BMG LabTech, Champigny sur Marne, France) 96-well microplate reader, thermostatically controlled at 37 °C, every 30 s for 15 min. The relative enzymatic activity was calculated using Equation (1). The IC50 of each compound corresponded to the lowest concentration at which the lipase activity was halved.

AML-12 mouse hepatocytes were maintained in Dulbecco’s modified Eagle’s medium (DMEM) (Sigma, Rehovot, Israel) supplemented with 10% fetal calf serum (FCS), 100 mg/L l-glutamine and 100 mg/L penicillin at 37 °C in 5% CO2. Cells were seeded in 12-well tissue culture plates, and once the desired confluence was reached, cells were synchronized with a 1-h pulse of 1 mM dexamethasone (Sigma). After 1 h, the medium was replaced with either high glucose (25 mM) or high fructose (25 mM) medium or high fructose (25 mM) containing a fatty acid complex of oleate and palmitate (ratio of 2:1) mixed with 10% bovine serum albumin. The final concentration of the palmitate/oleate mixture was 1 mM. Following 24 h of incubation, the medium was replaced, and cells were harvested in triplicates per treatment per time-point every 6 h for an additional 24 h.
