Flag-p53 purified from the T cells treated with BHB and two deacetylation inhibitors was analyzed by western blot using antibodies that recognize the acetylation of p53 K, K, or the C-terminal lysines, pan-acetylation of lysine Ac-K , as well as with BHB-K. H3K9 kbhb is enriched in active gene promoters and is associated with genes upregulated in the starvation-responsive pathway These results further support a role for CBP in p53 kbhb. Induction of pregulated genes is reduced in tissues of fasted mice under genotoxic conditions To explore the effect of p53 Kbhb in vivo, we analyzed thymus tissues obtained from fasted C57BL mice under genotoxic conditions. The relative expression level of each target gene was measured by qPCR and normalized to the level of actin. Blood samples were taken from a tail vein for determination of blood BHB concentrations using a ketone meter China, Alibaba. Western blot analysis of the purified p53 using BHB-K antibodies showed that the signal was lower in KR mutant and completely disappeared in the triple mutant Fig. Western blot analysis of p Detection of p53 kbhb in mouse thymus Six- to eight-week-old C57BL male mice were either fed a standard chow diet or fasted with free access to water for 48 h. After 24 h of transfection, the cells were suspended, diluted and re-seeded to ensure single clone formation. All mouse data represent the average of results obtained in five 6- to 8-week-old male mice. Similar results were obtained as in the induction of pexpressing H cells; doxorubicin treatment activated p53 and upregulated genes p21 and PUMA at the protein level. Thymus cells were obtained from all four groups. Cell growth assay One hundred and four U2OS cells were spread into six-well plates three replicates were performed. The experiments were carried out three times, and the averages of the data are presented. Histone kbhb has been detected in yeast, flies, mice, and human cells 13 , and a total of 44 histone kbhb sites have been identified in both human cells and in mouse livers Similar results of Kbhb on endogenous p53 activity, nutlin, an MDM2 inhibitor, was used to increase the level of endogenous p53 protein in U2OS. Since posttranslational modification of p53 is known to affect its activity 2 , 3 , 4 , 5 , 6 , 7 , 8 , we next investigated whether p53 kbhb also influences p53 activity. The use of ketogenic diets and calorie restriction also have therapeutic effects in human and mouse brain tumors Results p53 kbhb occurs in cells in the presence of BHB and in the thymus of fasted mice To explore whether kbhb occurs in p53, first, we purified and enriched this protein from T cells expressing Flag-tagged p53 and treated with BHB, pyruvate or glutamine.

Cell growth assay One hundred and four U2OS cells were spread into six-well plates three replicates were performed. In addition, we investigated the effect of kbhb on the apoptosis-inducing function of p53 in HCT cells treated with Nutlin Fig. Introduction The p53 protein is one of the most widely studied transcription factors. Untreated mice were used as controls. It is well-known that almost every kind of posttranslational modification that takes place in histones also occurs in p53 protein. Our findings thus show that BHB-mediated p53 kbhb is a novel mechanism of p53 activity regulation, which may explain the link between ketone bodies and tumor, and which may provide promising therapeutic target for cancer treatment. Induction of pregulated genes is reduced in tissues of fasted mice under genotoxic conditions To explore the effect of p53 Kbhb in vivo, we analyzed thymus tissues obtained from fasted C57BL mice under genotoxic conditions. Together, our results indicate that p53 undergoes kbhb. Then, 4 h later, the mice were euthanized, and the thymus was collected. The mass spectrometric analysis also revealed that the lysine residues and were also modified Fig. Detection of p53 kbhb and acetylation inside cells p53 kbhb was determined in T cells transfected with the plasmid expressing Flag-p53 before and after treatment with 10 mM BHB for 24 h. We focused on genes targeted by p53 4 , 8. The experiments were repeated three times. Flag-p53 purified from the T cells treated with BHB and two deacetylation inhibitors was analyzed by western blot using antibodies that recognize the acetylation of p53 K, K, or the C-terminal lysines, pan-acetylation of lysine Ac-K , as well as with BHB-K. Similar results of Kbhb on endogenous p53 activity, nutlin, an MDM2 inhibitor, was used to increase the level of endogenous p53 protein in U2OS. Ketone bodies are also linked to cancer. Measurement of BHB in mouse serum Six- to eight-week-old C57BL male mice each group consisted of five mice were either fed a standard chow diet five mice or fasted with free access to water five mice for 48 h. Methods Antibodies and plasmids The following antibodies were used in western blot assays: The results showed a small but significant reduction in the apoptosis of HCT cells in the presence of BHB compared to that of cells treated with Nutlin alone Fig. These results suggest that under conditions that favor p53 kbhb over acetylation, p53 gene regulatory activity is attenuated. After 24 h of transfection, the cells were suspended, diluted and re-seeded to ensure single clone formation. The Flag-p53 protein was purified as before and the purified protein was assayed by western blot using anti-p53 DO-1 or BHB-K or anti-pan-acetylation-lysine Ac-K antibodies. These results further support a role for CBP in p53 kbhb. This result was further confirmed in HCT cells, which are another kind of cells with wild-type p53 and a complete p53 signal pathway Fig.
