As a result of changes taking place independently in different evolutionary lineages, we observe a great diversity of mitochondrial genomes with respect to structure and gene content. In most cases, mitochondrial DNA has a circular shape, but linear molecules of mitochondrial DNA are also observed in some eukaryotes.

Progress has also been made in the field of pharmacognosy, which places substances of natural origin contained in plant raw materials at the center of attention. The beneficial effects of some of them have been known for years, while scientific evidence of their health-promoting properties was lacking for a long time. This was also the case with curcumin and the long road from its isolation in pure form in 1842 to the knowledge of its chemical structure in 1910. Due to the chemical properties of the molecule, curcumin is attributed with many health-promoting properties. These affect many organ systems including the skin, visual pathway, respiratory system, circulatory system, digestive system and nervous system. One of the complications that follow nerve damage is the loss of locomotor function in the animal and the development of inflammation within it. Curcumin has anti-inflammatory properties. This is confirmed by its inhibition of nuclear factor κB, a mediator in inflammatory processes. In addition, a very important field associated with neuronal dysfunction is the aging process. This is caused, among other things, by the presence of reactive oxygen species. The neuroprotective effect of curcumin allows to reduce their concentration caused by the accumulation of mutations within the mitochondrial DNA. The beneficial effect on the nervous system is due to the penetration of curcumin across the blood-brain barrier. However, its poor solubility significantly limits the therapeutic properties resulting from curcumin supplementation. Methods are currently being developed to increase its bioavailability using nanoparticles.</p>","PeriodicalId":20335,"journal":{"name":"Postepy biochemii","volume":"69 1","pages":"18-25"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10234562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
