ABSTRACT Introduction: In recent years, genetic engineering has made outstanding contributions to sports, and it has played a huge role in promoting the development of sports-related fields. Objective: We analyze the tissue source of bone growth and healing by studying the role of bone morphogenetic protein and transforming growth factors in fracture injuries caused by sports. Methods: We established a human fracture model to express the shape and content of bone morphogenetic protein and transforming growth factor during fracture healing. Results: In the fracture healing stage caused by different sports, the expression levels of the two genes are different. Bone morphogenetic protein has a high content in the osteogenesis stage of the membrane, while transforming growth factor is high in the cartilage ossification stage. Conclusion: Gene therapy for fractures caused by physical exercise has certain advantages. Osteoblasts and chondrocytes are involved in the synthesis of transforming growth factors. Level of evidence II; Therapeutic studies - investigation of treatment results.

Группа исследователей из Гарвардского университета в 2013 и последующих годах опубликовала серию статей об одном из трансформирующих факторов роста b - GDF-11. По данным этого коллектива, концентрация GDF-11 в крови и тканях млекопитающих с возрастом снижается. Искусственное повышение содержания GDF-11 у старых мышей путем ежедневных инъекций рекомбинантного GDF-11 или парабиоза в течение месяца с молодыми мышами существенно снижало и даже устраняло свойственные старости неблагоприятные изменения сердца, скелетных мышц, мозга. Статьи Гарвардской группы привлекли большое внимание научного сообщества, были комментированы в сотнях публикаций, и в них GDF-11 стали часто называть белком молодости. Капитальность заявки Гарварда стимулировала капитальность проверочных экспериментов с привлечением максимально надежных методик. Эти эксперименты расширили знания о GDF-11, но не подтвердили его права называться белком молодости. A research group at the Harvard University in 2013 and the next years has published a series of articles focusing on one of transforming growth factors b, GDF-11. According to these reports mammalian blood and tissue concentrations of GDF-11 decrease with age. Increasing the GDF-11 content in old mice using daily injections of recombinant GDF-11 or one-month parabiosis induced in young mice significantly reduced and even eliminated adverse, old age-specific changes in the heart, skeletal muscles, and brain. The reports of the Harvard group have attracted much attention of the scientific community, and were cited in hundreds of publications where GDF-11 was often called the protein of youth. The solidity of the Harvard team statement warranted solidity of test experiments, which used the most reliable methods. These experiments have expanded the knowledge of GDF-11 but did not confirm its right to be called a protein of youth.

The author describes DNA oncoviruses and RNA oncoviruses, their ways of infiltrating the host’s cells, and the possibilities of neoplastic transformation of cells by these microorganisms. The role of protooncogenesis and oncogenesis in both humans and animals is discussed. The transformation of cells by viruses is normally insufficient for oncogenesis; the cells also need to gain “immortality,” which usually requires 4-5 genetic changes (the so-called clonal development of cells), (Fig. 1). Oncoviruses remove suppressor growth factors while enhancing the effects that stimulate cell growth through e.g. hormones, cytokines, or transcription activators. In addition, the author discusses the role of the optimization principle in neogenesis.
