Description
Technical field
The present invention relates to biological technical field, more particularly to a kind of skeletal muscle specificity PCK1 of AAV1 viral vectors mediation
Expression vector and application thereof, recombination expression unit and gene therapy mode comprising the carrier.
Background technology
Phosphoenolpyruvate carboxykinase(phosphoenolpyruvatecarboxykinase, PEPCK)It is catalysis
Gluconeogenesis(gluconeogenesis)One rate-limiting enzyme of reaction, i.e., be changed into phosphoric acid enol form propanone by oxaloacetic acid and GTP
Acid, GDP and CO2Reaction.Tricarboxylic acid cycle is carried out in mitochondria, and PEPCK is then online grain respectively there are two types of isodynamic enzyme
PEPCK-M in body(mitochondrial form)With the PEPCK-C in endochylema(cytosolic form).PEPCK-C
Gene is PCK1 in people, plays an important role in gluconeogenesis.PCK1 has become first of liver gluconeogenesis and has clearly marked at present
Will object, the transcriptional level of the gene is the important indicator of clinically diabetes B evaluation in liver, i.e., if the mRNA tables of PCK1
Increase up to level, the rate of gluconeogenesis is just bound to increase.
The PCK1 gene codes protease of one 63kD, mainly there are three aspects for function:In liver and cortex renis
Expression, catalysis gluconeogenesis reaction;It is expressed in liver and white and brown adipose tissue, participates in the reaction of glycerine heteroplasia
(glyceroneogenesis);It is reacted being lost in(cataplerosis)In work, remove tricarboxylic acid cycle in anion
To greatly increase the dynamics of tricarboxylic acid cycle.However transcriptional activities of the PCK1 in different tissues is different.Except mainly depositing
In liver, PCK1 is also widely present in the tissue of mammal simultaneously, including small intestine, colon, mammary gland, adrenal gland, lung
And muscle, but the metabolism in these tissues is also indefinite.In addition, major functions of the PCK1 in different tissues
Also it is different, so particular conditions knock out in different tissues or overexpression PCK1 will cause a variety of different phenotypes.Positive reason
Under condition, PCK1 is not expressed in skeletal muscle or expression quantity is very low.PCK1 is changed into one with the energy of 6 ATP to be catalyzed pyruvic acid
A glucose, and during the anerobic glycolysis of skeletal muscle, it often decomposes a glucose and but can be only generated 2 ATP.Triglycerides
Content in skeletal muscle is directly proportional to PCK1, is main energy source.
The transgenic mice of PEPCK-C is overexpressed in muscle(PEPCK-Cmus)There is infusive phenotype.First,
PEPCK-CmusThe locomitivity of transgenic mice is significantly larger than control mice, can run 5 kilometers with 20 ms/min of speed, and right
0.2 kilometer can only be run under similary speed according to mouse, this may be related with the increase of triglycerides in skeletal muscle.Secondly,
PEPCK-CmusThe service life of transgenic mice is considerably longer than control mice, and can also give birth to normal mouse at 30-35 months
Offspring, most of mouse just lost fecundity at 12-18 months(Hakimi P1, Yang J, Casadesus G, et
al.Overexpression of the cytosolic form of phosphoenolpyruvatecarboxykinase
(GTP) in skeletal muscle repatterns energy metabolism in the mouse.J Biol
Chem. 2007;282(45):32844-32855.).
The transgene pig that PEPCK-C is overexpressed in skeletal muscle has also obtained the result similar with mouse.One kind is obtained
Similar with top beef characteristic, the high intramuscular fat content of low-fat content pork, obtains significantly on meat and mouthfeel
It is promoted, there is huge economic value.And PEPCK-C transgene pigs increase in fertility, therefore in excellent product
It has a wide range of applications in the breeding of kind.
Adeno-associated virus(Adeno-associated virus, AAV)The carrier safety barrier new as one kind,
Importance is just gradually recognized by researcher.It is parvovirus family member, is nonencapsulated linear ssdna virus, has
There is extensive host range, somatoblast can be infected but also infect non-dividing cell, and the long-term table of energy mediate foreign gene
It reaches.As important a member of viral vectors, AAV does not have apparent cytotoxic effect, and will not be as other viral vectors
The immune response for causing cell strong like that;Simultaneously when structure recombinates AAV viruses, the viral codings of itself of AAV are lacked completely
Sequence and only retain its both ends length be 145 bp terminal repeat(Inverted terminal repeat, ITR), from
And the possibility of its restructuring and expression oneself protein is effectively reduced, security is made to be further enhanced.Therefore, AAV is as one
The preferable gene therapy vector of kind, intriguing more and more and concern(Lu Y. Recombinant
adeno-associated virus as delivery vector for gene therapy-a review.Stem
Cells Dev. 2004; 13(1):133-145; Daly TM.Overview of adeno-associated viral
vectors. Methods Mol Biol. 2004; 246:157-165.).Senses of the AAV of different serotypes to different tissues
Dye ability slightly has difference, and wherein AAV1 is fine to the infection ability of skeletal muscle(Rebuffat A, et al. Comparison
of Adeno-Associated Virus Pseudotype 1, 2, and 8 Vectors Administered by
Intramuscular Injection in the Treatment of Murine Phenylketonuria.Hum Gene
Ther.2010;21(4):463-477.), the mode that direct multi-point injection purpose skeletal muscle can be used effectively infected.

Specificity overexpression in skeletal muscle.And point mutation is carried out to promoter sequence, has eliminated XhoI the and SalI enzymes in sequence
Enzyme site.The cDNA sequence of PCK1 is connected afterwards, and according to Codon degeneracy principle, the CDS sequences of PCK1 genes are carried out
Point mutation eliminates EcoRI and BglII restriction enzyme sites therein.PCK1 genes are imported in liver in order to reduce external source simultaneously
Expression is introduced into the miRNA of high expression in people's liver of 4 series connection again after PCK1 gene end codons --- miR-122's
Base complete complementary target sequence inhibits to import expression of the PCK1 genes in liver, virus is avoided to enter liver via blood circulation
