Sodium 4-phenylbutyrate (4-PBA sodium) is an inhibitor of HDAC and endoplasmic reticulum (ER) stress, used in cancer and infection research^[1].

Sodium 4-phenylbutyrate (Sodium phenylbutyrate) is an inhibitor of HDAC, inhibits the growth of NSCLC Cell Lines at 2 mM. Sodium 4-phenylbutyrate in combination with ciglitizone results in enhanced growth arrest of cancer cells^[1]. Sodium 4-phenylbutyrate (Sodium phenylbutyrate; 0-5 mM) inhibits ASFV infection in a dose-dependent manner. Sodium 4-phenylbutyrate also inhibits the ASFV late protein synthesis and disrupts the virus-induced H3K9/K14 hypoacetylation status. Sodium 4-phenylbutyrate and Enrofloxacin act synergistically to abolish ASFV replication^[2]. Addition of Bafilomycin A1 results in accumulation of LC3II, whereas Benzenebutyric acid (4-PBA) substantially reduces this accumulation. LPS decreases the level of p62, whereas Benzenebutyric acid reverses this decrease upon LPS stimulation for 48 h. The percentage of cells with LPS-induced AVOs is increased at 48 h, whereas Benzenebutyric acid significantly reduces this percentage. Specifically, the percentage of cells with AVOs decreases from 61.6% to 53.1% upon Benzenebutyric acid treatment, supporting that Benzenebutyric acid inhibits LPS-induced autophagy. As a positive control for autophagy inhibition, bafilomycin A1 is used. The percentage of cells with LPS-induced AVOs is reduced by bafilomycin A1 treatment. The decreased OC area and fusion index observed after Benzenebutyric acid treatment are not observed with knockdown of ATG7. Inhibition of NF-κB using BAY 11-7082 and JSH23 reduce the LC3 II level upon LPS stimulation and completely abolish the inhibitory effect of Benzenebutyric acid on LPS-induced effects^[3].

LPS induces significant bone loss and decreases bone mineral density (BMD), bone volume (BV/TV), and trabecular thickness (Tb. Th) compared with PBS alone, whereas trabecular space (Tb. Sp.) is increased. Sodium 4-phenylbutyrate (Sodium phenylbutyrate) attenuates LPS-induced bone loss. Treatment with Sodium 4-phenylbutyrate increases BMD, BV/TV, and Tb. Th. compared with LPS alone, in addition to decreasing the enlargement of Tb. Sp., but no change is observed when mice are treated with Sodium 4-phenylbutyrate alone. OC.S/BS as assessed by TRAP staining is also significantly reduced when Sodium 4-phenylbutyrate is administered to LPS-treated mice. However, OC.N/BS tends to decrease, although not with statistical significance, when mice are treated with Sodium 4-phenylbutyrate and LPS. These results indicate that the effect of Sodium 4-phenylbutyrate on OC from LPS-treated mice is to reduce its size rather than number. Consistent with these findings, a marker of bone resorption in vivo, serum CTX-1 which is elevated by LPS treatment is decreased when Sodium 4-phenylbutyrate administered to LPS-injected mice. However, co-treatment with Sodium 4-phenylbutyrate do not significantly affect the levels of serum ALP and osteocalcin, 2 markers of bone formation in vivo, compared with LPS alone. Sodium 4-phenylbutyrate also reduces the LPS-induced rise in serum MCP-1, indicating that Sodium 4-phenylbutyrate decreases systemic inflammation induced by LPS^[3].

Briefly, viable cells, as judged by trypan blue dye exclusion, are seeded at a density of 4 × 10⁴ cells/mL in 60-mm dishes in RPMI 1640 with 10% fetal bovine serum and 0.35% agarose on a base layer of 0.7% agarose. DMSO, TSA, or PB is added to both bottom and top agarose layers. Assays are performed in triplicate on at least three separate occasions, and colonies are counted at 10-14 days^[1].

Mice^[3]
Female 10-week-old C57BL/6J mice are housed in the pathogen-free animal facility of IRC. Animals are randomized into the following 4 groups: vehicle control (n=5), vehicle+Benzenebutyric acid (n=6), LPS (n=6), and LPS+Benzenebutyric acid (n=6). Mice are treated with LPS in 200 μL phosphate-buffered saline (PBS) once a week (5 mg/kg, i.p.) for 3 weeks. Sodium 4-phenylbutyrate (Benzenebutyric acid) solution is prepared by titrating equimolecular amounts of Benzenebutyric acid and sodium hydroxide to reach pH 7.4; mice are injected daily intraperitoneally in 200 μL PBS (or with PBS as a vehicle) at a dose of 240 mg/kg for 3 weeks. Mice are sacrificed by CO₂ asphyxiation. To determine the bone mineral density (BMD) and microarchitecture of the long bone, the right femur is scanned. Scans are performed with an effective detector pixel size of 6.9 μm and a threshold of 77-255 mg/cc. Trabecular bone is analyzed in a region 1.6 mm in length and located 0.1 mm below the distal femur growth plate^[3].
