Abstract
The invention discloses a kind of skin anti-aging ability detection method and its detection primer and kit, a kind of detection method of skin anti-aging ability, described detection method includes the following steps: (1) extracting the DNA of sample to be tested;(2) specific primer is utilized, using DNA obtained by step (1) as template, carries out fluorescent quantitative PCR detection, wherein the specific primer is forward primer 1, forward primer 2 and reverse primer 3;(3) according to fluorescent quantitative PCR testing result obtained by step (2), skin anti-aging ability is detected.The present invention provides a kind of method of the single nucleotide polymorphism of economic quickly detection skin anti-aging gene, easy to operate, economical and efficients.
Description
Technical field
The invention belongs to field of biotechnology, and in particular to a kind of skin anti-aging ability detection method and its detection primer
And kit.
Background technique
As social economy develops at full speed, skin health and beauty are gradually paid attention to by the public.Maintain the weight of skin health
Point is skin anti-aging, oxidation resistance and skin moisturizing anti-wrinkle ability.And these maintain the body of skin health to adjust
Inner principles are determined by a variety of key function related genes.Simultaneously also studies have found that, skin health key function gene
Single nucleotide polymorphism (SNP) determine the activity of gene, to influence the maintenance of skin health stable state.
Skin anti-aging/anti-oxidant index can reflect whether a people has maintenance " young state " potential quality.Skin is anti-ageing
Always/oxidation resistance is stronger, and " young state " potential quality is higher.There is a set of natural Antioxidative Defense System in human body, it is intracorporal
Peroxidase gene CAT, glutathione peroxidase gene GPX1, dehydrogenase gene NQO1, superoxide dismutase base
Because SOD2 cooperates with the removing and degradation of responsible interior free yl, peroxide, anti-oxidant balance in vivo is maintained.Wherein NQO1 base
Because belonging to NAD (P) H dehydrogenase (quinone) family, it is responsible for catalysis quinone Double electron reduction reaction.The enzyme is by NADH or NADPH conduct
Electron donor, the reduction reaction of quinones in catalytic body, prevents quinone that the free radical that an electron reduction process generates occurs.
There are different SNP by NQO1 in crowd, wherein crucially there are TT:CT:CC in the site gene coding region rs1800566.TT/
CT genotype oxidation resistance is general, and CC genotype oxidation resistance is strong.SOD2 is the one of ferrimanganic superoxide dismutase family
Member.It encodes a kind of mitochondrial protein for forming tetramer, and every subunit combines a manganese ion.This protein and phosphorous oxide
The superoxide radical that acidification generates combines, and is translated into hydrogen peroxide and diatomic oxygen.SOD2 exists different in crowd
SNP, wherein crucially code area rs4880 deposits CC:TC:TT in site.C allele carrier's oxidation resistance is poor, TT base
Because type anti-aging ability is stronger.Skin oxidation resistance genetic test anticipated that cutaneous sensibility speciality, take protection early
Measure avoids skin care is improper from causing the irreversible aging of skin.
Loss of moist caused by skin aging, long-term mental burden and sleep insufficiency, excessive being exposed to the sun all easily promote skin
, there is wrinkle in relaxation.Collagen is a kind of hmw protein, elastomer albumen and collagen fibrous proteins by mutually intersecting
Fork is wound a strong elastic network(s), and skin is made to keep solid and flexible state.Studies have shown that COL1A2 and skin
The wrinkling resistance of skin is related.The pro-alpha2 chain of the genes encoding Type I collagen, triple helices are by two alpha1 chains
It is formed with an alpha2 chain.Type i collagen is a kind of fibroplastic collagen, is present in most of connective tissues,
Rich content in bone, cornea, corium and tendon.There are different SNP by COL1A2 in crowd, wherein crucially gene coding region
There are CC:TC:TT in the site rs11979919.CC/TC genotype anti-light aging ability is general, and wrinkling resistance is general.TT genotype
Anti-light aging capability improving, wrinkling resistance are good.Gene unit point amino acid of differences will be such that collagen decomposition rate obviously increases
Add, skin is easy to generate wrinkle, if do not taken effective nursing, skin aging fast speed.
In conclusion the relevant key function gene of skin health can react the ability of skin health maintenance well,
That is skin anti-aging ability.However current cutaneous gene method for detecting single nucleotide polymorphism, it is more multiple that there is also test procedures
It is miscellaneous, it the defects of inconvenient benefit and deficiency, therefore establishes by establishing a set of economic quickly skin appraisal procedure, passes through
Simple and quick method checks the difference of skin health maintenance ability gene vigor between individual, thus between comprehensive assessment individual
Skin health simultaneously provides the care plans changed and improved, becomes technical problem urgently to be resolved.
Summary of the invention
Therefore, at present based on fluorescent quantitative PCR technique, the cutaneous gene monokaryon of skin anti-aging ability is detected
Nucleotide polymorphism detection method, there is also test procedures it is complex, inefficient and inconvenient the defects of and deficiency, this
Invention provides a kind of new skin anti-aging ability detection method and its detection primer and kit, to solve above-mentioned skill
Art problem.
Basic technique principle of the invention are as follows: the present invention carries out the inspection of different SNP using the method that PCR product Tm is migrated
It surveys.Its brief principle is, when for SNP site design primer, using unified reverse primer, and forward primer is with SNP site knot
Tail (Fig. 1).5 ' ends of the forward primer of the different genotype of SNP adjust the Tm of different genotype product by increasing GC simultaneously
Value.It can determine whether which kind of SNP product is by the difference of Tm value between product.The key of this method is that forward primer GC is duplicate
Selection, if can play the role of distinguishing different SNP.If it is homozygote genotype, it should be single melting curve peak type.
And containing the corresponding genotype of more GC in the end of forward primer 5 ', melting curve Tm should be higher than in the end of forward primer 5 ' and contain
There is the corresponding genotype of more GC.Simultaneously if it is heterozygote genotype, theory can generate bimodal melting curve or unimodal and Tm
It is located in the middle melting curve.By interpretation melting curve, the SNP parting of related gene can be confirmed, and further interpretation skin
The anti-aging ability of skin.
In order to solve the above technical problems, one of the technical solution that the present invention takes are as follows: a kind of inspection of skin anti-aging ability
Survey method, described detection method includes the following steps:
(1) DNA of sample to be tested is extracted;
(2) specific primer is utilized, using DNA obtained by step (1) as template, carries out fluorescent quantitative PCR detection, wherein described
Specific primer is forward primer 1, forward primer 2 and reverse primer 3;
(3) according to fluorescent quantitative PCR testing result obtained by step (2), skin anti-aging ability is detected.
Wherein step (1) is to extract the DNA of sample to be tested.The sample to be tested is the sample to be tested of this field routine, packet
Serum is included, is organized, cell, mouth swab sample or other samples to be tested, preferably mouth swab sample.Wherein it is described to
The extracting method of the DNA of sample is the DNA extraction method of this field routine, as long as can extract the DNA in sample to be tested
Demand of the present invention can be met out, the DNA extraction method is preferably comprised phenol chloroform method etc., or utilizes commercially available
The DNA of DNA extraction agent box extracting sample.
