In recent decades, there has been a growing interest in the role of symbiotic human microbiota in the regulation of metabolism and functioning of host immune system. The symbiosis between a macroorganism and its microbiota has given rise to the concept of a holoorganism. Interactions between the components of a holoorganism have formed in the process of coevolution, resulting in the acquisition by microbiotic metabolites of a special role of signaling molecules and main regulators of molecular interactions in the holoorganism. As elements of signaling pathways in the host organism, bacterial metabolites have become essential participants in various physiological and pathological processes, including tumor growth. At the same time, signaling metabolites often exhibit multiple effects and impact both the functions of the host cells and metabolic activity and composition of the microbiome. This review discusses the role of microbiotic metabolites in the induction and prevention of malignant transformation of cells in the host organism and their impact on the efficacy of anticancer therapy, with special emphasis on the involvement of some components of the microbial metabolite molecular ensemble in the initiation and progression of tumor growth.

Among the other, RNAi is involved in silencing of transposable elements and in inhibition of virus infection in various eukaryotic organisms. Recent experimental studies demonstrate few cases of viral replication suppression via complementary interactions between the mammalian small RNAs and viral transcripts. Presentation of the hypothesis: It was found that >50% of the human genome is transcribed in different cell types and that these transcripts are mainly not associated with known protein coding genes, but represent noncoding RNAs of unknown functions. We propose a hypothesis that mammalian DNAs encode thousands RNA motifs that may serve for antiviral protection. We also presume that the evolutional success of some groups of genomic repeats and, in particular, of transposable elements (TEs) may be due to their ability to provide antiviral RNA motifs to the host organism. Intense genomic repeat propagation into the genome would inevitably cause bidirectional transcription of these sequences, and the resulting double-stranded RNAs may be recognized and processed by the RNA interference enzymatic machinery. Provided that these processed target motifs may be complementary to viral transcripts, fixation of the repeats into the host genome may be of a considerable benefit to the host. It fits with our bioinformatical data revealing thousands of 21-28 bp long motifs identical between human DNA and human-pathogenic adenoviral and herpesviral genomes. Many of these motifs are transcribed in human cells, and the transcribed part grows proportionally to their lengths. Many such motifs are included in human TEs. For example, one 23 nt-long motif that is a part of human abundant Alu retrotransposon, shares sequence identity with eight human adenoviral genomes. Testing the hypothesis: This hypothesis could be tested on various mammalian species and viruses infecting mammalian cells.

After entering the human organism vitamins or their precursors can undergo chemical modification, changing their biological properties and regulatory activity. For many decades, vitamins were considered mainly as precursors of enzyme cofactors, and hypovitaminosis was interpreted as a deficiency of a particular metabolite resulting from enzyme's insufficient activity. However, with the development of molecular biology techniques and breakthrough in understanding of gene expression regulation and cell signaling mechanisms, as well as in molecular mechanisms of diseases associated with impaired functions, it became clear that there are significantly more active forms of vitamins, and their functions in the human body are more diverse than it had been suggested previously. The purpose of this review was to consider vitamins' and vitamins' derivatives regulatory and anti-tumor role and their potential for clinical application as main or adjuvant drugs for malignant neoplasms treatment. Material and methods. The present review is based on the results of literature analysis conducted in the Scopus, PubMed, Science Direct databases for the keywords «vitamin A AND cancer», «retinoids AND cancer», «vitamin D AND cancer», «vitamins AND cancer», «vitamins AND cancer». The search depth was 6 years (2016-2021). Results. Active forms of hydrophilic and lipophilic vitamins are key participants in the processes of chromatin remodeling, genome stability maintaining, covalent modification of proteins, including signaling and regulatory ones, and also act as chemical messengers themselves. Therefore, vitamin deficiency is associated with autoimmune and chronic diseases such as cancer, atherosclerosis, diabetes mellitus, etc. This review considers the regulatory role of active forms of vitamins, their derivatives and vitamin-like substances as well as their involvement in the process of carcinogenesis. Conclusions. Modern studies confirm the high therapeutic potential of vitamins: the use of pharmacological doses of vitamins or their derivatives may help to prevent or fight non-communicable diseases, including cancer.
