Description

PTEN oxidative inactivation inducer containing 1,1-diethoxyethanein as an active ingredient and uses thereof

[0001] The present invention relates to a PTEN oxidative inactivator comprising 1,1-diethoxyethane (1,1-DEE) as an active ingredient and its uses. More specifically, the present invention relates to a PTEN oxidative inactivation inducer comprising 1,1-diethoxyethane as an active ingredient and its uses, for example, as a composition for the prevention, treatment, or improvement of diseases requiring oxidative inactivation of PTEN, such as a pharmaceutical composition, a cosmetic composition, a food composition, or a feed composition, and a method for detecting the redox state of PTEN.

[0002] The PI3K / Akt (Phosphoinositide-3-kinase / protein kinase B) pathway is an important signaling system that regulates various cellular processes such as proliferation, survival, and differentiation. When ligands such as growth factors bind to RTKs (receptor tyrosine kinases), PI3K is activated, and PIP2 (phosphatidylinositol (4,5)-bisphosphate) is phosphorylated to PIP3 (phosphatidylinositol (3,4,5)-trisphosphate). When PIP3 accumulates in the cell membrane, Akt is activated, which regulates various downstream effectors.

[0003] PTEN (Phosphatase and tensin homolog deleted on chromosome 10) possesses lipid phosphatase function by dephosphorylating PIP3 to PIP2, playing an important role as a negative regulator of the PI3K / Akt signaling pathway. PTEN is regulated by various post-translational modifications, and changes such as oxidation, acetylation, or s-nitrosylation can inhibit PTEN's lipid phosphatase function. For example, the Cys124 residue, a catalytic nucleophile of PTEN, is readily oxidized by reactive oxygen species (ROS), which leads to the formation of a disulfide bond between the Cys124 and Cys71 residues, thereby inhibiting PTEN's function.

[0004] Inhibition of PTEN can increase the concentration of PIP3 and activate the PI3K / Akt pathway through Akt activation. This can lead to enhanced insulin signaling and improved insulin sensitivity. This mechanism presents new possibilities for the treatment of metabolic diseases, and related research is actively underway.

[0005] The PI3K / Akt pathway plays a particularly important role in regulating insulin sensitivity. When insulin binds to the transmembrane RTK IR (insulin receptor), the PI3K / Akt pathway is activated through autophosphorylation. Through this, Akt activation promotes glycolysis and glycogen synthesis, and increases the cellular uptake and metabolism of glucose.

[0022] Accordingly, the inventors made diligent efforts to investigate the physiological functions of 1,1-diethoxyethane (1,1-DEE) and confirmed that 1,1-DEE induces oxidative inactivation of PTEN (phosphatase and tensin homolog deleted on chromosome 10) through the formation of disulfide bonds between Cys124 and Cys71 residues (see Experimental Examples 2 and 3), that oxidative inactivation of PTEN induces increased phosphorylation at Ser473 and Thr308 of Akt, thereby activating Akt (see Experimental Examples 4 and 5), and that activation of Akt can accelerate the rate of glycolysis by increasing phosphorylation at the Ser483 residue of PFKFB2 (6-phosphofructo-2-kinase / fructose-2,6-biphosphatase 2) (see Experimental Example 6).

[0023] In addition, it was confirmed that combined treatment with 1,1-DEE and insulin can increase Akt activation and improve insulin sensitivity, and that 1,1-DEE can also have the effect of alleviating palmitic acid-induced insulin resistance (see Experimental Example 7), thereby completing the present invention.

[0071]

[0072] Meanwhile, the scope of the present invention is not limited by the effects described above.

[0073] Figure 1 shows 1,1-DEE identified in various ethanol batches: (A) HepG2 cells were treated with 100 mM E1, E2, or E3 for 10 minutes. (B) Lyophilization process flow of 100 mM E1, E2, and E4. (C) Cells were treated with 100 mM E1, E2, or E4 or the corresponding lyophilized samples described in (B) for 10 minutes. After treatment, cell extracts were alkylated with 10 mM NEM, followed by non-reducing or reducing electrophoresis and staining with PTEN and β-actin antibodies. (D) Presence and chemical structure of 1,1-DEE confirmed by GC-MS analysis of E1.

[0074] Figure 2 indicates that 1,1-DEE can induce concentration-dependent PTEN oxidation: (A) C2C12, MEF, AC16, and Ea.hy926 cells were treated with various concentrations of 1,1-DEE (0–50 mM) for 10 minutes. (B) C2C12 cells were treated with 1,2-DEE at the same concentrations as in (A). After alkylating the cell lysates with 10 mM NEM, Western blot analysis was performed using PTEN and GAPDH antibodies to determine the levels of PTEN oxidation. (C) HepG2 cells were transfected with HA-tagged pCGN PTEN WT, C71S, C124S, or C71S / C124S. After transfection, the cells were treated with 10 mM 1,1-DEE for 10 minutes. After treatment, the cells were lysed and alkylated with 10 mM NEM, and then immunoblotting was performed using an antibody against the HA-tag.

[0075] Figure 3 shows that 1,1-DEE can induce time-dependent PTEN oxidation: (A) C2C12, MEF, AC16, and EA.hy926 cells were treated with 10 mM 1,1-DEE for 120 minutes at various time intervals. (B) C2C12 cells were treated with 10 mM 1,2-DEE under the same conditions as in (A). After alkylating the cell lysates with 10 mM NEM, reductive or non-reductive electrophoresis was performed, and immunoblot analysis was conducted using PTEN antibodies.

[0076] Figure 4 indicates that PTEN oxidation induced by 1,1-DEE can activate the Akt signaling pathway: (A) C2C12 cells were treated with various concentrations of 1,1-DEE for 10 minutes. (B) C2C12 cells were treated with 10 mM 1,1-DEE for 120 minutes at various time intervals. Immunoblot analysis was performed using cell lysates and antibodies against phosphorylated Akt and total Akt at Ser473 and Thr308.

[0077] Figure 5 illustrates that PTEN oxidation induced by 1,1-DEE is mediated by ROS generation: (A) HepG2 cells were treated with 10 mM 1,1-DEE or 0.5 mM H2O2 for 10 minutes. Subsequently, the cells were stained with 10 μM DCFH-DA for 30 minutes, and representative images of the stained cells were obtained using a fluorescence microscope (10x magnification). (B) HepG2 cells were treated with 0.5 mM H2O2 for 10 minutes or with 10 mM 1,1-DEE for 30 minutes at various time intervals. After staining the cells with 10 μM DCFH-DA, flow cytometry was performed using the FITC channel at 10,000 events per sample. (C) HepG2 cells were pretreated with 10 mM NAC for 120 minutes, followed by treatment with 10 mM 1,1-DEE for 120 minutes at various time intervals. After alkylating the cell lysate with 10 mM NEM, non-reducing or reducing immunoblotting was performed and analyzed using antibodies against PTEN, phosphorylated Akt, Akt, and GAPDH.

[0078] Figure 6 shows that 1,1-DEE can promote glycolysis through Akt activation: (A) AC16 cells were pretreated with 10 μM MK-2206 for 24 hours, followed by treatment with 10 mM 1,1-DEE for 30 minutes. (B) AC16 cells were pretreated with 10 μM Ebselen for 60 minutes, followed by treatment with 10 mM 1,1-DEE for 30 minutes at various time intervals. Cell lysates were alkylated with 10 mM NEM, and Western blot analysis was performed using antibodies against PTEN, phosphorylated Akt, Akt, phosphorylated PFKFB2, PFKFB2, and GAPDH.

[0079] Figure 7 indicates that 1,1-DEE can improve insulin sensitivity and alleviate palmitic acid-induced insulin resistance: (A) C2C12 cells were treated with various concentrations of 1,1-DEE (0–10 mM) for 10 minutes in the presence or absence of 20 nM insulin. (B) C2C12 cells were pretreated with 500 μM palmitic acid for 24 hours, followed by treatment with 10 mM 1,1-DEE, 20 nM insulin, or both for 10 minutes. Cell lysates were alkylated with 10 mM NEM, and Western blot analysis was performed using antibodies against PTEN, phosphorylated Akt, Akt, and GAPDH.

[0080] Figure 8 illustrates a method for detecting the redox state of PTEN using 1,1-DEE. 1,1-DEE induces the generation of ROS within cells, of which H2O2 reacts with HCO3- to form HCO4-. When PTEN is exposed to HCO4-, some PTEN molecules form reversible intracellular disulfide bonds with Cystein 71 residues, which can oxidize the Cystein 124 residues in the active site. Subsequently, treatment with NEM causes the reduced PTEN to alkylate and form a PTEN-NEM complex, which increases the molecular weight and decreases mobility in SDS-PAGE under non-reducing conditions.

[0081] Hereinafter, a PTEN oxidative inactivation inducer comprising 1,1-diethoxyethanein as an active ingredient and its uses according to a specific embodiment of the invention will be described in detail. However, this is presented as one example of the invention and does not limit the scope of the invention, and it is obvious to those skilled in the art that various modifications to the embodiment are possible within the scope of the invention.

[0176] Gas sampling

[0177]

[0178] The researchers used a continuous irrigation system for transurethral resection of the prostate (TURP) and vaporization. Gases generated during the cutting and cauterization process were collected in the upper part of the bladder. The mixture of the solution and gas used for perfusion was drawn through tubing into a large vessel connected to a vacuum pump. A portion of the gas collected above the fluid in the vessel was directed from the exhaust gas outlet to tubing connected to a Tenax adsorption tube (Tenax GR; Japan Analytical Industry, Tokyo, Japan). The flow rate of the gas directed into the Tenax adsorption tube was maintained at 0.05 L / min using a gas flow pump (MP-S30; SIBATA, Tokyo, Japan). Measurements using a Tedlar Bag (Sigma-Aldrich) showed that a mixture of gas and room air was generated at a rate of approximately 45 L per hour. For quantification, 1 L of surgical gas was injected into a Tenax adsorption tube at a flow rate of 0.05 L / min.

The frozen samples were freeze-dried overnight to completely remove volatile and water-containing components. The following day, the contents of each Falcon tube were reconstituted with serum-free DMEM prior to cell treatment.

[0190]

[0191] 5. DCFH-DA staining for ROS detection

[0192] Total intracellular reactive oxygen species (ROS) levels were evaluated according to a previous study [Kim, H. and X. Xue, Detection of Total Reactive Oxygen Species in Adherent Cells by 2',7'-Dichlorodihydrofluorescein Diacetate Staining. J Vis Exp, 2020(160)]. Briefly, cells were seeded into 6-well plates and cultured overnight under 5% CO2 conditions at 37°C. After treatment, the cells were washed once with serum-free DMEM and cultured with 10 μM DCFH-DA at 37°C for 30 minutes. Subsequently, the cells were washed once with serum-free DMEM and twice more with PBS. Finally, the cells were rapidly imaged using a fluorescence microscope.

After 1,1-DEE treatment, cells were incubated with a predetermined concentration of DCFH-DA at 37°C for 30 minutes. Subsequently, cells were collected with Trypsin-EDTA (#25300-062, Gibco) and washed with cold PBS. Intracellular ROS levels were quantified immediately by excitation at 485 nm and emission at 530 nm, and mitochondrial peroxide levels were quantified by excitation at 510 nm and emission at 580 nm.

In summary, cells were lysed in a lysis buffer containing 20 mM Tris-HCl (pH 7.5), 150 mM NaCl, 5% glycerol, 0.1% NP-40, a phosphatase inhibitor, a protease inhibitor, and 10 mM NEM. The cell lysates were sonicated and then centrifuged at 13,000 rpm for 10 minutes. The supernatant was then collected, and protein concentrations were measured using the Pierce™ BCA Protein Quantification Kit (Thermo Fisher Scientific, Waltham, MA, USA).

[0200]

[0201] 8. Statistical Analysis

[0203]

[0204] <Result>

[0205] 1. Evaluation of the Effect of 1,1-DEE on PTEN Oxidation According to Ethanol Batch

[0206] In this study, the effects of various ethanol batches provided by commercial sources on the redox status of PTEN were evaluated. HepG2 cells were used in the experiment, and the effects of ethanol batches at various concentrations on the oxidation rate of PTEN were investigated. As a result, significant differences in the oxidation rate of PTEN were observed depending on the ethanol batch, even at the same concentration. In particular, the E1 batch induced PTEN oxidation more strongly than the E2 and E3 batches. Furthermore, when E1 was mixed with E2 or E3, the level of PTEN oxidation tended to decrease compared to the oxidation effect of E1 (Fig. 1A).

[0207] Additionally, it was confirmed that the odor characteristics of batch E1 differed significantly from other ethanol batches. E1 exhibited strong alcoholic and fruity scents, whereas these scents were relatively less pronounced in batches E2 and E3. This suggests the possibility that specific compounds included in batch E1 may affect the redox state of PTEN.

[0208] To characterize the compound properties of batches E1, E2, and E4, volatile compounds in each batch were analyzed. Batch E4 exhibited odor characteristics similar to E1 (Fig. 1B); to confirm this, volatile compounds were evaporated by freeze-drying 100 mM ethanol, and the dried samples were then reconstituted with PBS or 100 mM E2. Subsequently, HepG2 cells were treated for 10 minutes with the ethanol of each batch (100 mM, E1, E2, E4) or the corresponding dried samples. The experimental results showed that batches E1 and E4 strongly induced PTEN oxidation compared to E2 and the control group. However, the dried samples of E1, E2, and E4 did not show similar effects regardless of the reconstitution condition (PBS or E2) (Fig. 1C). This indicates that the volatile compounds evaporated during the freeze-drying process.

[0209] Subsequently, additional compounds were identified in batches E1, E2, E3, and E4 through GC-MS analysis. As a result of the analysis, the aroma compound 1,1-DEE (1,1-diethoxyethane) was found at high concentrations in E1 and E4, but was not detected in E2 and E3. The results of GC-MS-based fragmentation analysis of 1,1-DEE in batches E1 and E4, along with the identified chemical structure, are shown in Figure 1D. Thus, it was demonstrated that 1,1-DEE may play a novel role in cellular functions mediating the redox regulation of PTEN.

[0210]

[0211] 2. Evaluation of whether 1,1-DEE induces PTEN oxidation in a concentration-dependent manner

[0212] To determine whether 1,1-DEE can exhibit novel molecular functions by regulating the redox state of PTEN, cells were treated with various concentrations of 1,1-DEE, and PTEN oxidation levels were evaluated. 1,1-DEE-mediated PTEN oxidation was observed within 10 minutes of treatment in various cell lines, including C2C12, MEF, AC16, and Ea.hy926. In C2C12 and MEF cells, PTEN oxidation was induced after treatment with 1,1-DEE at a concentration of 1 mM, while in AC16 and Ea.hy926 cells, similar levels of oxidation were achieved at 1,1-DEE at a concentration of 5 mM (Fig. 2A). 1,1-DEE-mediated oxidation occurred in a concentration-dependent manner, with oxidation levels increasing with higher concentrations. In contrast, 1,2-DEE, an isomer of 1,1-DEE, failed to induce PTEN oxidation in C2C12 cells at various concentrations. This suggests a specific conformation-dependent function of 1,1-DEE in the redox regulation of PTEN (Fig. 2B).

[0213] To investigate the underlying mechanism of 1,1-DEE-mediated PTEN oxidation, C2C12 cells were transfected with an HA-tagged pCGN vector containing broad-type (WT) PTEN or PTEN mutants (C71S, PTEN C124S, or PTEN C71 / 124S) prior to treatment with 1,1-DEE. As a result, PTEN oxidation was detected in cells transfected with WT PTEN, but not in cells transfected with PTEN C71S, PTEN C124S, or PTEN C71 / 124S (Fig. 2C). This indicates that 1,1-DEE mediates the oxidative inactivation of PTEN by inducing the formation of disulfide bonds between Cys124 and Cys71 residues.

[0214]

[0215] 3. Evaluation of whether 1,1-DEE induces time-dependent PTEN oxidation

[0216] In this study, we investigated the time-dependent regulatory patterns of 1,1-DEE on the redox status of PTEN. Various cell types, including C2C12, MEF, AC16, and Ea.hy926, were treated with 1,1-DEE for 120 minutes. Interestingly, PTEN oxidation levels began to increase just 5 minutes after the start of 1,1-DEE treatment, peaked after 10 minutes, and then gradually returned to basal levels after 120 minutes (Fig. 3A). However, 1,2-DEE failed to induce PTEN oxidation in C2C12 cells even after 120 minutes of treatment (Fig. 3B). Thus, it was demonstrated that specific forms of 1,1-DEE can induce reversible oxidation of PTEN in a time-dependent manner.

[0218] 4. Evaluation of PTEN oxidation by 1,1-DEE and the subsequent regulation of Akt activation

[0219] In this study, Akt activation induced by 1,1-DEE-induced PTEN oxidation was investigated. C2C12 cells were treated with various concentrations of 1,1-DEE for 10 minutes or with 10 mM 1,1-DEE for various durations over 120 minutes. Akt phosphorylation at Ser473 and Thr308 was found to be enhanced after treatment with 1 mM 1,1-DEE for 10 minutes, suggesting increased Akt activity. Akt phosphorylation increased in a concentration-dependent manner due to 1,1-DEE, indicating negative regulation of PTEN in the Akt signaling pathway (Fig. 4A). Furthermore, similar to the reversible oxidation of PTEN mediated by 1,1-DEE, it was confirmed that Akt phosphorylation at Ser473 and Thr308 was also reversible. The levels of phosphorylated Akt473 and Akt308 increased after 5 minutes of 1,1-DEE treatment, peaked at 10 minutes, and then gradually returned to baseline levels after 120 minutes (Fig. 4B). This suggests that oxidative inhibition of PTEN induced by 1,1-DEE may lead to reversible activation of Akt.

[0220]

[0221] 5. Evaluation of whether 1,1-DEE-induced PTEN oxidation is mediated by ROS generation

[0222] In this study, to investigate the underlying mechanism of 1,1-DEE-induced PTEN oxidation, ROS production levels in cells were evaluated after 1,1-DEE treatment. DCFH-DA staining results confirmed that cytoplasmic ROS levels increased 10 minutes after 1,1-DEE treatment compared to the control group (Fig. 5A). Flow cytometry analysis showed that ROS levels increased within 5 minutes of treatment, peaked at 10 minutes, and returned to basal levels after 30 minutes. This indicates that 1,1-DEE can reversibly increase ROS production (Fig. 5B).

[0223] Next, to analyze the relationship between ROS generation and 1,1-DEE-induced PTEN oxidation, cells were pretreated with the ROS scavenger NAC for 120 minutes, followed by treatment with 1,1-DEE. NAC pretreatment was found to reduce 1,1-DEE-induced PTEN oxidation. This implies that ROS generated by 1,1-DEE mediates the oxidative inactivation of PTEN. Additionally, NAC pretreatment reduced the phosphorylation levels of Akt at Ser473 and Thr308 (Fig. 5C). These results suggest a regulatory mechanism of 1,1-DEE-induced ROS generation in the PTEN / Akt signaling pathway.

[0225] 6. Evaluate whether 1,1-DEE promotes glycolysis through Akt activation

[0226] Akt activation is known to regulate the rate of glycolysis through the phosphorylation of PFKFB2 (6-phosphofructo-2-kinase / fructose-2,6-biphosphatase 2) at Ser483 residues. PFKFB2 is a dual-function enzyme involved in both the synthesis and degradation of Fru-2,6-P2 (fructose-2,6-biphosphate), which controls eukaryotic glycolysis. Phosphorylation of PFKFB2 enhances its activation, generating Fru-2,6-P2 and further upregulating glycolysis. Accordingly, to investigate the effects of Akt activation on glycolysis, phosphorylation of PFKFB2 at Ser483 in AC16 cells was evaluated. As a result, 1,1-DEE treatment was shown to increase PTEN oxidation and Akt activation through phosphorylation at Ser473, and exposure to 1,1-DEE for 5 minutes resulted in phosphorylation of PFKFB2 at the Ser483 residue (Fig. 6A).

[0227] To determine whether Ser483 phosphorylation of PFKFB2 is regulated by Akt activation, AC16 cells were pretreated with the Akt inhibitor MK-2206 and then treated with 1,1-DEE. Pretreatment with MK-2206 reduced both Akt activation and PFKFB2 phosphorylation, indicating that glycolysis can be regulated by Akt activation induced by 1,1-DEE (Fig. 6A).

[0228] Next, cells were pretreated with Ebselen to investigate the relationship between 1,1-DEE-induced ROS generation and glycolysis. Interestingly, Ebselen pretreatment reduced the increase in 1,1-DEE-induced PFKFB2 phosphorylation (Fig. 6B). These results suggest that 1,1-DEE-induced ROS generation can further increase glycolysis through the phosphorylation of PFKFB2 by mediating the oxidative inactivation of PTEN and Akt activation.

[0229]

[0230] 7. Evaluate whether 1,1-DEE improves insulin sensitivity and palmitate-induced insulin resistance.

[0231] In this study, the effects of 1,1-DEE on insulin signaling and insulin sensitivity in C2C12 cells were investigated. Treatment with 1,1-DEE induced PTEN oxidation and Akt activation, which were evaluated by phosphorylated-Akt473 and phosphorylated-Akt308 levels. When cells were co-treated with 1,1-DEE and insulin, Akt phosphorylation at Ser473 and Thr308 increased compared to treatment with 1,1-DEE or insulin alone (Fig. 7A). This indicates that 1,1-DEE can enhance insulin signaling and insulin sensitivity.

[0232] To evaluate the effects of 1,1-DEE on the regulation of insulin resistance, an in vitro cellular model of insulin resistance was established using palmitic acid. These cells were treated with either 1,1-DEE or insulin for 10 minutes. It was confirmed that Akt phosphorylation at Ser473 and Thr308 residues in insulin-resistant cells was significantly reduced compared to control cells (Fig. 7B). This indicated that the insulin resistance model was successfully induced through palmitic acid treatment. Importantly, co-administration of 1,1-DEE and insulin upregulated Akt phosphorylation in insulin-resistant cells (Fig. 7B). This suggests that 1,1-DEE can alleviate palmitic acid-induced insulin resistance by mediating Akt activation.
