Background technology
Basal metabolic rate refers in natural temperature environment, and human body (includes digestive system, i.e. fasting more than two hours) under inactive state, and sustain life the required minimum energy consumed. These energy are mainly used in keeping the function of each organ, drain (kidney), removing toxic substances (liver), musculation etc. as breathed (lung), heart beating (heart), glandular secretion (brain and other nervous system), filtering. Basal metabolic rate along with the age increases or loses weight and reduces, and can increase along with muscle and increase. Disease, feed, variation of ambient temperature, bear pressure level change and all can change the energy expenditure of human body, thus affecting basal metabolic rate.
The heat that basal metabolic rate difference determines human body consumption every day is different, if therefore to be lost weight by diet, then must take in energy < consumed energy. Meanwhile, basal metabolic rate also determines human body catabiotic difference under different exercise intensitys, therefore in the middle of body building process, if intensity is excessive causes that energy expenditure is too much, can cause many unhealthy even harmful sufferers.
BMR is the index of each organ of human body, tissue energy consumption, therefore closely related with gene.

(2) pcr amplification
The present embodiment detects RS16892496 and RS7832552 simultaneously. The detection of each SNP needs a pair upstream and downstream primer, two polymorphic primer totally 4 PCR primer, needs 8 primers altogether. The detection of each SNP needs to do two pipe pcr amplifications, for preventing the reaction of false positive etc, whether successful weighs PCR, add a pipe negative control group, being 5 pipe PCR altogether, described negative control group genomic templates and reaction system are the same, but do not have primer.
According to different detection site, prepare PCR reaction system with corresponding primer respectively in following ratio: 2.5 μ l10 × PCR buffer, 2 μ ldNTPs, 0.5 μ l primer sets, hot start Taq polymerase 0.15 μ l, genomic templates 80mg, adding ultra-pure water to cumulative volume is 25 μ l.
Will be equipped with the Eppendorf test tube of reaction solution to put in ABI9700PCR instrument, it is as follows that reaction condition is set: 95 DEG C of 3min of denaturation; 94 DEG C of 30s of thermal cycle, 60 DEG C of 30s, 72 DEG C of 30s, 35 circulations; Extend 72 DEG C of 3min. After reaction terminates, take out test tube.
Owing to 5 pipe pcr amplification reactions are synchronously performed in same PCR instrument, in order to realize the high efficiency of detection, specificity, require that the Tm value of 8 PCR primer is close, need for this first to carry out substantial amounts of DNA sequence software analysis to design PCR primer, and carry out the optimization of Tm value by substantial amounts of experiment and determine the reasonability of design, the detection of this test kit each gene SNP polymorphism is not only relatively independent but also connect each other, indivisible.
(3) agarose gel electrophoresis detection
Product after amplification is carried out sepharose electrophoresis detection, and process is as follows: 3g agarose, adds 100mL deionized water, microwave-oven-heating 1min, adds 5 μ LGoldview dyeing liquors, make the agarose gel of 3% when being cooled to 60 DEG C. PCR primer 10 μ L and 6 × tbe buffer liquid 0.8 μ L mixes loading, voltage 100V electrophoresis 15min. Reading result under uviol lamp and take pictures, gained sepharose electrophoresis detection figure is as shown in Figure 1.
It is as follows that detection obtains 2 gene types analysis results:
SNP | Genotyping result |
RS16892496 | TT |
RS7832552 | TT |
According to above genotyping result, the contribution margin (Y) of the gene pairs basal metabolic rate of this tester is: 2.7+2.55=5.25KG.According to being RS16892496GG > the LBM 2.55KG more than the LBM of TC and CC type than many 2.7KG, the RS7832552TT type of TT and TG type of TG/TTGG type. Then according to below equation:
Male: LBM=(0.32810*W)+(0.33929*H)-29.5336+Y
Women: LBM=(0.29569*W)+(0.41813*H)-43.2933+Y
BMR=P(kcal/day)=370+(21.6*LBM)
This tester is male, therefore calculates its BMR=1837kcal/day. Energy expenditure in its daily life can be calculated according to following table:
Seldom or not move Dailykilocaloriesneeded=BMRx1.2
More slight exercise (1 3 days/weekly) Dailykilocaloriesneeded=BMRx1.375
Moderate exercise (3 5 days/weekly) Dailykilocaloriesneeded=BMRx1.55
Severe exercise (6 7 days/weekly) Dailykilocaloriesneeded=BMRx1.725
Pole severe tempers (twice daily) Dailykilocaloriesneeded=BMRx1.9
Be engaged in more slight exercise for as daily in this man, then the energy expenditure of its every day is approximately: 1723*1.375=2525kcal.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
