Description

CRISPR/Cas9 system causing congenital deafness and application thereof in preparation of model pig nuclear donor cells
Technical Field
The invention belongs to the technical field of biology, relates to a CRISPR/Cas9 system causing congenital deafness and application thereof in preparing model pig nuclear donor cells, and in particular relates to the CRISPR/Cas9 system and application thereof in preparing TMC1 gene mutation congenital genetic deafness clone pig nuclear donor cells.
Background
Congenital deafness (congenital deafness) refers to deafness caused by abnormalities or genetic factors in pregnancy, childbirth, and is mostly sensorineural deafness. Congenital deafness can be divided into two major categories, hereditary and non-hereditary. 43 syndrome type deafness genes and 99 non-syndrome type deafness genes have been found. Wherein, a plurality of genes can cause autosomal dominant hereditary non-syndrome type deafness and autosomal recessive hereditary non-syndrome type deafness simultaneously, and TMC1 is one of them. TMC1 was first reported in 2002 to have multiple mutations that lead to dominant (DFNA 36) and recessive (DFNB 7/11) hereditary hearing loss. TMC1 is a necessary component for detecting acoustic wave stimulation by auditory hair cells in the inner ear, but its physiological role and deafness causing mechanism are still unclear at present, so development of an animal model for congenital genetic deafness caused by TMC1 mutation is urgently needed to study its pathogenic mechanism and therapeutic regimen. Pigs are main meat supply animals for a long time, are easy to breed and raise on a large scale, have lower requirements on ethical morals, animal protection and the like, have similar body size and physiological functions to human beings, and are ideal human disease model animals.
Gene editing is a biotechnology that has been greatly developed in recent years, and includes editing means from gene editing based on homologous recombination to ZFN, TALEN, CRISPR/Cas9 based on nuclease, wherein CRISPR/Cas9 technology is currently the most advanced gene editing technology. Currently, gene editing techniques are increasingly applied to the production of animal models.

The invention aims at overcoming the defects of the prior art and providing an sgRNA target and a gRNA for TMC1 gene editing.
It is another object of the present invention to provide a CRISPR/Cas9 system for porcine TMC1 gene editing.
It is a further object of the present invention to provide for the use of the CRISPR/Cas9 system.
The aim of the invention can be achieved by the following technical scheme:
an sgRNA target for TMC1 gene editing, the sequence of which is shown in SEQ ID NO: 21.
A gRNA for TMC1 gene editing, the sequence of which is shown in SEQ ID NO: 25.
A gRNA expression vector for pig TMC1 gene uses pKG-U6gRNA with the complete sequence shown in SEQ ID NO.3 as a vector skeleton to express the gRNA for TMC1 gene editing.
Preferably, the expression vector of the present invention is a vector comprising the sequence of SEQ ID NO:32 and SEQ ID NO:33, and a double-stranded DNA molecule having a cohesive end obtained by annealing the single-stranded DNA shown in FIG. 33 is inserted into the BbsI restriction enzyme site of the vector backbone pKG-U6 gRNA.

To increase the gene editing capacity of the Cas9 Plasmid, we modified pU6gRNA-eEF1a-mNLS-hSpCas9-EGFP-PURO (abbreviated as granule pKG-GE 3) on the basis of the vector pX330-U6-Chimeric_BB-CBh-hSpCas9 (abbreviated as PX 330) purchased from adedge (Plasmid #42230,from Zhang Feng lab). The map of PX330 is shown in fig. 1, modified as follows:

The recombinant cell is applied to construction of TMC1 gene knockout cloned pigs; preferably in constructing cloned pigs with TMC1 gene knocked out congenital genetic deafness.
Compared with the prior art, the invention has at least the following beneficial effects:
(1) The subject (pig) of the invention has better applicability than other animals (rats, mice, primates).
Rodents such as rats and mice have great differences from humans in terms of body type, organ size, physiology, pathology and the like, and cannot truly simulate normal physiological and pathological states of humans. Studies have shown that more than 95% of drugs that are validated in mice are ineffective in human clinical trials. In the case of large animals, primates are animals that are closest to human relatives, but are small in size, late in sexual maturity (mating begins at 6-7 years old), and single animals, the population expansion rate is extremely slow, and the raising cost is high. In addition, primate cloning is inefficient, difficult and costly.
The pig is an animal which has the closest relationship with human except primate, and has the similar size, weight, organ size and the like to human, and is very similar to human in terms of anatomy, physiology, nutrition metabolism, disease pathogenesis and the like. Meanwhile, the pigs are early in sexual maturity (4-6 months), have high fertility and have more piglets, and can form a larger group within 2-3 years. In addition, the cloning technology of pigs is very mature, and the cloning and feeding cost is much lower than that of primates; the pig is taken as a meat animal for a long time, and the pig is taken as a disease model animal, so that the requirements on animal protection, ethics and the like are low.
(2) According to the invention, four gRNAs are designed aiming at the pig TMC1 gene, and the high-efficiency gRNAs are screened from the gRNAs and then the pre-set targets are knocked out, so that the workload of later-stage identification and screening can be effectively reduced, and the PCR product sequencing can be directly used for detecting the gene editing efficiency.
(3) The efficient expression vector of Cas9 modified by the invention is adopted for gene editing, and the editing efficiency is improved by more than 100% compared with the original vector.
(4) The efficient expression vector of the Cas9 modified by the invention is adopted for gene editing, and the genotype [ homozygous mutation (including homozygous mutation of the same variation of the double alleles and homozygous mutation of different variations of the double alleles), heterozygous mutation or wild type ], of the obtained cells can be analyzed according to the sequencing result of the target gene PCR product, wherein the probability of obtaining the homozygous mutation is 30% -50%, which is greatly superior to the probability (lower than 5%) of obtaining the homozygous mutation in a model preparation method (namely fertilized ovum injection gene editing material) using embryo injection technology.
(5) The homozygous mutant monoclonal cell strain obtained by the invention is used for cloning somatic cell nuclear transfer animals, so that cloned pigs containing target gene homozygous mutation can be directly obtained, and the homozygous mutation can be stably inherited.
The method of microinjection of gene editing material into fertilized ovum and embryo transplantation adopted in mouse model production is not suitable for large animal (such as pig) model production with long gestation period because the probability of directly obtaining homozygous mutant offspring is very low (less than 5%), and the offspring need to be hybridized and bred. Therefore, the method for editing and screening the positive editing monoclonal cells in vitro by using the primary cells with high technical difficulty and high challenge is adopted, and the corresponding disease model pigs are directly obtained by somatic cell nuclear transfer animal cloning technology in the later period, so that the manufacturing period of the model pigs can be greatly shortened, and the manpower, material resources and financial resources are saved.
The invention lays a solid foundation for obtaining the congenital deafness pig model by a gene editing means, is helpful for researching and revealing the pathogenesis of the congenital deafness caused by TMC1 mutation, can be further used for researching drug screening, drug effect detection, disease pathology, gene therapy, cell therapy and the like, can provide effective experimental data for further clinical application, and further provides a powerful experimental means for successfully treating the congenital deafness caused by TMC1 mutation. The invention has great application value for research and development of congenital genetic deafness drugs and revealing pathogenesis of the disease.
