Definitions
- the present invention relates to a composition that can be used for a specific purpose, such as a composition for slowing skeletal muscle.
- Muscles are the basis of daily activities such as standing, walking, and maintaining posture. Therefore, in order to maintain the quality of life, there is a desire to maintain muscle mass as much as possible and increase muscle mass if possible, regardless of age or sex. In addition, humans and athletes (for example, athletes, sports enthusiasts, athletes, etc.) who actively prefer exercise are required to increase their muscle mass as much as possible in order to improve their athletic performance.
- QOL quality of life
- flail a state between a healthy state and a state requiring nursing care
- locomotive syndrome locomotive syndrome
- Muscle is composed of bundles of muscle fibers. Muscle fibers are classified into slow muscle fibers (Type I) and fast muscle fibers (Type II) based on properties such as contraction tension, contraction speed, and fatigue tolerance. Muscles with many slow muscle fibers have the property of having low contraction force and contraction rate but are less likely to fatigue, and contribute to endurance. On the other hand, muscles with many fast muscle fibers have a large contraction force and contraction speed, but are prone to fatigue. In addition, muscles with many slow muscle fibers act as anti-gravity muscles. In patients with disuse muscular atrophy, the muscles change from slow muscles to fast muscles, and the fast muscles are more likely to atrophy due to inactivity than the slow muscles, which interferes with daily activities such as difficulty walking and bedridden. It leads to a state of atrophy. Maintaining or strengthening slow muscles can prevent or ameliorate lack of exercise and difficulty in activities of daily living by maintaining endurance and strength.

- Example 10 Preparation of administration product> The freeze-dried powder of Bifidobacterium breve FERM BP-11 175 with saline and diluted to a concentration of 5 ⁇ 10 8 cfu / mL, to obtain viable cells administered products. A viable cell-administered product of Bifidobacterium Breve FERM BP-11175 was heated at 90 ° C. for 30 minutes to obtain a heat-sterilized product.
- the experimental animals were allowed to freely ingest Lab MR stock feed (manufactured by Northan Industries) and tap water after purchase at the age of 7 weeks. After acclimatization for 1 week, the experimental animals were controlled (5 mL / kg body weight / day of physiological saline) and live Bifidobacterium cells (2 mL / day / day of live cells) (bacteria).
- Bifidobacterium heat sterilizer administration group (2 mL / day / animal in heat sterilizer / animal (1 ⁇ 10 9 cells / animal)
- oral administration of the administered product using an oral sonde was continued once a day for 4 weeks in each mouse.
- the experimental animals were treated under sevoflurane anesthesia to remove the soleus and gastrocnemius muscles.
- the gastrocnemius muscle was used to measure the proportion of slow muscle fibers by the following procedure. That is, the excised gastrocnemius muscle was sliced, and slow muscle fibers were stained by immunohistochemical staining using Anti-SERCA2 ATPase antibody (Abcam). For each group, three visual fields of the central part of the medial gastrocnemius muscle were observed under a microscope, and the staining rate (slow muscle fiber ratio) was measured for a total of 450 fibers.
- Figure 1 shows the proportion of slow muscle fibers in each group.
- the slow muscle fiber staining images of each group are shown in FIGS. 2 to 4.
- dark areas are slow muscle fibers and bright areas are fast muscle fibers.
- Administration of Bifidobacterium breve FERM BP-11175 increased the proportion of slow muscle fibers compared to the control.
- a marked increase in the proportion of slow muscle fibers was confirmed in the heat-sterilized body-administered group than in the live-cell-administered group.
- the slow muscle fiber ratio increased by 3.80% in the live cell administration group
- the slow muscle fiber ratio increased by 12.70% in the heat sterilized body administration group.
- the soleus muscle is a signal pathway involved in slowing skeletal muscle (Zhang et al., Int J Biol Sci, 13 (9), 1152-1162 (2017); Suwa et al., J. Appl. It was used for the evaluation of Physiol, 95, 960-968 (2003).
- AMPK activated AMP-activated protein kinase
- PPC-1 ⁇ peroxysome growth factor activating receptor ⁇ -conjugating factor-1 ⁇
- RNA was extracted from a part of the excised soleus muscle using RNeasy Mini Kit (Qiagen), and a complementary DNA (cDNA) library was prepared by PrimeScript RT Reagent Kit (Takara Bio Inc.).
- cDNA complementary DNA
- SYBR Premix Ex Taq2 (Takara Bio Inc.)
- PCR was performed to quantify the expression level of PGC-1 ⁇ at the mRNA level. At this time, the expression level of PGC-1 ⁇ was standardized based on the expression level of GAPDH and calculated as a relative value with respect to the control.
- the expression level of PGC-1 ⁇ is shown in FIG. Administration of Bifidobacterium breve FERM BP-11175 increased the expression level of PGC-1 ⁇ compared with the control. In particular, a marked increase in the expression level of PGC-1 ⁇ was confirmed in the heat-sterilized body-administered group than in the live-cell-administered group. Specifically, the expression level of PGC-1 ⁇ increased 1.31 times in the viable cell administration group and 1.90 times in the heat sterilized body as compared with the control. ..
- Protein was extracted from a part of the excised soleus muscle using RIPA buffer (CST), and the amount of phosphorylated AMPK (active AMPK) was quantified by Western blotting. At this time, the phosphorylated AMPK amount was standardized based on the total AMPK amount and calculated as a relative value with respect to the control.
- CST RIPA buffer
- the amount of phosphorylated AMPK is shown in FIG.
- Administration of Bifidobacterium Breve FERM BP-11175 increased the amount of active AMPK compared to the control. Specifically, the amount of active AMPK increased 1.42 times in the viable cell administration group and 1.48 times the amount of active AMPK in the heat sterilized body administration group as compared with the control.
- compositions that can be used for a specific purpose, such as a composition for slowing skeletal muscle.
