The application belongs to the technical field of biological medicine, and particularly relates to an anti-aging ergothioneine composition for improving mitochondrial function and a preparation method thereof. The composition comprises the following components: ergothioneine, sea hao polysaccharide and entada extract. The ergothioneine has good mitochondrial targeted antioxidant activity, can up-regulate the expression of Sirt1 to activate PGC-1a, and promote mitochondrial biosynthesis; the sea hao polysaccharide is helpful to restore mitochondrial function, promote the generation of mitochondrial high-energy phosphoric compounds, improve cell activity and energy supply for regeneration, and can up-regulate the expression of key genes for mitochondrial biosynthesis and ATP synthase related genes. The entada extract can synergize with the ergothioneine and the sea hao polysaccharide, significantly down-regulate the expression of aging related proteins such as p53, p21 and p16 in cells, simultaneously inhibit the transcription of aging related genes, and has a good protective effect on aging cells.

With supporting experimental data, this disclosure teaches that IF1 protein activity is a molecular determinant of lifespan, therein explaining why different species have different maximal lifespans, and it teaches a IF1 protein / fragment (or sequence variant thereof), or a fusion protein thereof, optionally a fusion protein comprising a Cell Penetrating Peptide (CPP) sequence, as an agent to slow / delay / reduce aging in a subject, optionally as a component of a cosmetic, optionally to treat an age-correlated disease / disorder. Moreover it teaches other inhibitors of F1F0 ATP hydrolysis, including small molecules, of a number of different scaffolds, for this purpose. Furthermore, with supporting experimental data, it teaches that compounds that slow the ATP-hydrolysing mode of ATP synthase are useful for treating various diseases and disorders, including cancer, particularly cancers that utilise the Warburg effect.

This invention discloses a photosynthetic nanomotor powered by a biomolecular motor and its preparation method, belonging to the field of colloidal motors. This invention aims to address the current limitations of research on the rotational dynamics of FoF1-ATP synthase molecular machines, which is limited to the motion of single and isolated objects. The photosynthetic nanomotor is prepared based on supramolecular self-assembly technology through the reconstruction of thylakoid vesicles and lecithin vesicles. The photophosphorylation system on the thylakoid membrane surface is reconstructed on the photosynthetic nanomotor. Utilizing the preserved biomolecular motor FoF1-ATPase as the power engine, under external visible light irradiation, protons generated by the photosystem accumulate in the photosynthetic liposome motor, driving the FoF1-ATPase to synthesize the energy currency ATP. Through metabolic reactions, light energy is converted into chemical energy ATP, ultimately generating self-propulsion. Due to its unique energy currency regeneration capability, the photosynthetic liposome motor has broad application prospects in the biomedical field.

The present invention relates to novel in vivo uses in the treatment of non-tuberculous Mycobacterium, in particular Mycobacterium avium complex bacteria.

The application relates to the field of biomaterials, and particularly relates to application of a giant salamander mucus extract hydrolysate in preparation of an anti-dentin sensitivity agent. The anti-dentin sensitivity agent comprises a hydrolysate retaining the biological activity of SSAD, the hydrolysate being a product of reduction of the giant salamander mucus extract by an acid solution with a pH value of 1-5, and the product comprising five active proteins, namely MHC class I molecule alpha chain, homeobox protein Hox-D13, abnormal heavy chain 3 of axonemal dynein, ATP synthase protein and cytochrome b; the particle size of the giant salamander mucus extract is 1-50 mu m; and the pH value of the anti-dentin sensitivity agent is 5.5-7.5. The giant salamander mucus extract is treated by the acid solution to obtain the hydrolysate containing the multiple active proteins, the hydrolysate can effectively promote deep closure of dentin tubules, and has long-term stable biocompatibility; the pH value is controlled to ensure that the biological activity is completely retained, and the curative effect of the anti-dentin sensitivity agent is remarkably improved.
