Description

Technical Field

[0001] The present invention relates to the technical field of cell enzymolysis, and specifically to an enzymolysis device for regulating histone acetylation by targeting SIRT1. Background Art

[0002] During the process of using an enzymolysis device to perform enzymolysis operation on cells, a nanocarrier loaded with an enzymolysis regulation component is intravenously injected into an organism. Through targeted delivery in vivo, the nanocarrier specifically recognizes and binds to cells containing SIRT1. Once reaching the target position, the histone acetylation detection and feedback module starts to monitor the histone acetylation level in real time and transmits the signal to the control system. According to the feedback signal, the control system activates the energy supply and drive system to regulate the release or activity of the SIRT1 regulator, so as to achieve precise regulation of the histone acetylation level. For example, if an increase in the acetylation level is detected, the control system drives the SIRT1 activator to be released from the nanocarrier and act on SIRT1 to promote its deacetylation effect on histones; if the acetylation level decreases, the relevant components are adjusted to inhibit the activity of SIRT1 or promote the supply of its substrates to restore the acetylation level to normal.

[0003] To improve the targeting effect of the nanocarrier in vivo, the nanocarrier is combined with a magnetic material (such as superparamagnetic iron oxide nanoparticles) to endow it with magnetic response ability. Under the guidance of an external magnetic field, the magnetic nanocarrier can move more precisely and directionally to the target cells. During the intravenous injection of the magnetic nanocarrier, in the injection pipeline, due to the action of magnetic force and hydrodynamic factors, the nanocarrier may agglomerate due to local flow rate changes, adsorption on the pipe wall, and the interaction of collisions. This will not only affect the distribution and targeting effect of the nanocarrier in vivo, but may also cause blood vessel blockage. Therefore, we propose an enzymolysis device for regulating histone acetylation by targeting SIRT1. Summary of the Invention

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Example 1, please refer to Figures 1-9 , an enzymatic device for regulating histone acetylation by targeting SIRT1 shown in the figure, including an operating frame 1 for delivering a nanocarrier, and a ligand specifically recognizing and binding to the SIRT1 cell surface receptor is modified on the surface of the nanocarrier; It should be noted here that: the ligand is a peptide ligand. Some short peptides can be designed to specifically recognize the SIRT1 cell surface receptor. These peptides are short chains composed of amino acids, and their amino acid sequences can be designed according to the binding sites of the target receptor. For example, by analyzing the structure of the SIRT1 receptor binding domain, the key amino acid sequence interacting with it is determined, and then a complementary peptide sequence is synthesized; A magnetic material for assisting targeted positioning is arranged inside the nanocarrier, and further includes: An L-shaped piston tube 2 for supplying and delivering the nanocarrier is arranged on the operating frame 1, and a processing assembly for preventing the agglomeration of the nanocarrier conveyed inside the L-shaped piston tube 2 is arranged on the operating frame 1; The processing component includes a mixing cylinder 301 fixed on the operating frame 1. One end of the L-shaped piston tube 2 communicates with the inside of the mixing cylinder 301. The front end of the mixing cylinder 301 is connected to a syringe 302 in a communicating manner. The rear end of the mixing cylinder 301 is rotatably connected to a liquid storage cylinder 303 through a rotating component. A liquid supply component for supplying liquid to the inside of the mixing cylinder 301 is provided on the liquid storage cylinder 303. A driving component for driving the liquid storage cylinder 303 is provided on the mixing cylinder 301. The end of the liquid storage cylinder 303 is in a communicating state and is rotatably connected to a piston cylinder 304. A connecting component for connecting the piston cylinder 304 is provided on the operating frame 1. A buffer solution for maintaining the pH value and ionic strength of the nanocarrier is stored inside the piston cylinder 304. An extrusion component for assisting liquid discharge is provided on the L-shaped piston tube 2 and the piston cylinder 304; It should be noted here that: during the process of enzymatically digesting cells using an enzymatic digestion device, it is necessary to intravenously inject a nanocarrier loaded with an enzymatic digestion regulation component into an organism. During the injection process, through the mutual cooperation of components such as the processing component, liquid supply component, rotating component, and driving component, the pH value and ionic strength of the magnetic nanocarrier are adjusted. An appropriate pH value can maintain the stability of the surface charge of the nanocarrier, causing electrostatic repulsion between the nanocarriers. At the same time, the buffer solution can adjust the ionic strength, avoiding the compression of the double electric layer caused by high ionic strength, thereby ensuring that the electrostatic repulsion formed by the surface charge of the nanocarrier effectively plays a role and preventing the aggregation of magnetic nanocarriers during injection and transportation; It is worth noting here that: the enzymatic digestion regulation component of the nanocarrier includes enzymes, enzyme inhibitors, or other regulatory factors that can specifically act on the SIRT1 pathway; Magnetic nanocarriers usually have magnetic materials added during their preparation process, such as iron oxide nanoparticles. These magnetic materials enable the nanocarriers to respond to an external magnetic field. After being injected into an organism, by applying a magnetic field at the target site, the nanocarriers are guided to specific tissue or cell regions, further enhancing the targeting property and facilitating the enzymatic digestion regulation component to play a role at the required position; The buffer solution can be a phosphate buffer solution, which is composed of sodium dihydrogen phosphate and disodium hydrogen phosphate. Its pH value is usually between 7.2 - 7.4, which is close to the physiological pH value of the organism. During the injection of magnetic nanocarriers, the phosphate buffer solution can provide a stable ionic environment, maintain the surface charge state of the nanoparticles, prevent aggregation caused by charge changes, and at the same time, the ionic components in the phosphate buffer solution can shield the mutual attraction between the nanoparticles to a certain extent.

During the abutting process, the transmission pin 801, the L-shaped frame 702, the mounting ring 701 and the L-shaped pipe 602 are forced to perform a centering contraction movement. When the end of the transmission pin 801 does not abut against the spherical protrusion 802, through the elastic force of the first spring 706 on the telescopic component, the transmission pin 801, the L-shaped frame 702, the mounting ring 701 and the L-shaped pipe 602 are forced to return, so that the L-shaped pipe 602 performs a reciprocating gathering and dispersing movement while rotating.

During the sliding process of the piston plate 1001 inside the L-shaped piston tube 2, through the extrusion action of the piston plate 1001, the nano-carriers filled inside the L-shaped piston tube 2 are extruded and conveyed into the mixing cylinder 301 and finally injected into the organism through the syringe needle 302. During the sliding process of the piston plate 1001 inside the piston cylinder 304, through the extrusion action of the piston plate 1001, the buffer solution inside the piston cylinder 304 is conveyed into the mixing cylinder 301 through the liquid storage cylinder 303, the liquid outlet pipe 601, the bellows pipe 603 and the L-shaped pipe 602.

[0027] In this solution: an enzymatic hydrolysis device for regulating histone acetylation by targeting SIRT1 includes the following steps: During the process of using the enzymatic hydrolysis device to perform enzymatic hydrolysis on cells, it is necessary to introduce the nanocarrier loaded with the enzymatic hydrolysis regulation component into the organism by intravenous injection. During the injection process, the nanocarrier is pre-filled inside the L-shaped piston tube 2, and then the pre-prepared buffer solution is filled inside the piston cylinder 304. After filling, through the interaction of the transmission assembly and the extrusion assembly, the two piston plates 1001 slide inside the L-shaped piston tube 2 and the piston cylinder 304 respectively. During the process of the piston plate 1001 sliding inside the L-shaped piston tube 2, through the extrusion of the piston plate 1001, the nanocarrier filled inside the L-shaped piston tube 2 is extruded and transported into the mixing cylinder 301 and finally injected into the organism through the syringe 302. During the process of the piston plate 1001 sliding inside the piston cylinder 304, through the extrusion of the piston plate 1001, the buffer solution inside the piston cylinder 304 is transported into the mixing cylinder 301 through the liquid storage cylinder 303, the liquid outlet pipe 601, the bellows pipe 603 and the L-shaped pipe 602. Through the transportation of the nanocarrier and the buffer solution, the buffer solution and the nanocarrier are mixed inside the mixing cylinder 301. During the mixing process, the buffer solution can adjust the PH value and ionic strength of the magnetic nanocarrier. The appropriate PH value can maintain the stability of the surface charge of the nanocarrier, causing electrostatic repulsion between the nanocarriers. At the same time, the buffer solution can adjust the ionic strength to avoid the compression of the double electric layer caused by high ionic strength, so as to ensure the effective exertion of the electrostatic repulsion formed by the surface charge of the nanocarrier and prevent the aggregation of the magnetic nanocarrier during injection and transportation. And during the process of delivering the buffer solution, through the mutual cooperation of the rotating component and the driving component, the liquid storage cylinder 303 is driven to rotate at the end of the mixing cylinder 301. During the rotation process, through the connection of the telescopic component and the liquid outlet pipe 601, each group of L-shaped pipes 602 is driven to rotate. Through the rotation of the L-shaped pipes 602 and the delivery of the buffer solution on the L-shaped pipes 602, while ensuring the mixing of the buffer solution and the nano-carriers, the mixed liquid is slightly stirred, increasing the dispersion degree of the nano-carriers in the fluid, further reducing the probability of agglomeration of the nano-carriers due to magnetic force. And during the rotation of the liquid storage cylinder 303 and the L-shaped pipes 602, the end of the transmission pin 801 on the L-shaped frame 702 abuts against the spherical protrusion 802 inside the mixing cylinder 301 in sequence. During the abutting process, the transmission pin 801, the L-shaped frame 702, the mounting ring 701 and the L-shaped pipes 602 are forced to perform a centering contraction movement (the contracted state is shown in Figure 9 ). And when the end of the transmission pin 801 does not abut against the spherical protrusion 802, through the elastic force of the first spring 706 on the telescopic component, the transmission pin 801, the L-shaped frame 702, the mounting ring 701 and the L-shaped pipes 602 are forced to reset (the reset state is shown in Figure 8 ), so that the L-shaped pipes 602 perform a reciprocating gathering and dispersing movement while rotating. Through the reciprocation and dispersion of the L-shaped pipes 602, it is convenient for the buffer solution delivered on the L-shaped pipes 602 to mix with the nano-carriers at different positions inside the mixing cylinder 301, ensuring the mixing effect of the nano-carriers and the buffer solution.
