Classical chemotherapy is one of the main cancer treatments, but it often causes many side effects that may cause non-specific drug action. This is mainly due to the lack of significant differences between cancer and normal cells as well as drug resistance. To reduce the side effects and increase the specificity and the selectivity of chemotherapeutics to cancer cells, new methods of their delivery to tumors are being sought. One of these methods is the application of nanoparticles (NPs), e.g. Quantum Dots (QDs) as drug delivery platforms. This review describes the most popular NPs in chemotherapy, including quantum dots, gold nanoparticles, dendrimers, micelles, and liposomes. The review describes also a strategy of design and synthesis of NPs, mechanism of cellular uptake, as well as intracellular degradation and toxicity of NPs.</p>","PeriodicalId":20335,"journal":{"name":"Postepy biochemii","volume":"68 2","pages":"196-208"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40564101","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}

The mucosal immune response is essential for the effective elimination of invading pathogens. Unfortunately, most vaccines which are administered intramuscularly by injection do not induce an adequate protective immune response on mucous membranes. For example, after intramuscular injection, the level of secretory IgA antibodies is low and often insufficient to successfully combat the pathogen. On the other hand, mucosal-induced immunity produces a long-lasting effect in the form of a local and systemic response to the pathogen. Moreover, the administration of such vaccines does not generate hazardous medical waste and their application does not require the presence of qualified medical personnel. Therefore, intensive research into vaccines administered via the mucosal route is ongoing. An obstacle in the development of mucosal vaccines is the natural defense mechanisms of the mucosa, the overcoming of which requires the use of specialized adjuvants. Currently, there are no such formulations on the market.</p>","PeriodicalId":20335,"journal":{"name":"Postepy biochemii","volume":"68 2","pages":"179-188"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40566047","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}

On May 13, the journal Nature published two articles on the first isolation of messenger ribonucleic acid (mRNA), which is an intermediate product between a gene and a protein. Just two weeks later, on May 27, the first letter of the genetic code, phenylalanine, was discovered. These discoveries made it possible to understand how genetic information is encoded and processed, thus causing the dynamic development of molecular biology. The breakthroughs of 1961 concerned not only nucleic acids. On April 12, the first human, Yuri Gagarin, entered space. Eight years later, in 1969, Neil Armstrong made his first walk on the moon, uttering the famous phrase: It is a small step for man, but a great leap for humanity. The era of conquering and learning about the cosmos has begun, mainly motivated by the natural curiosity of man and the desire to learn about the surrounding reality. The environmental factors in space are very different from terrestrial conditions, which raises questions about their effects on living organisms. In search of answers, a variety of scientific research has been carried out at the International Space Station (ISS) for over twenty years. As space travel is set to become more common in the near future, detailed studies of the effects of long-term space missions on the human body are required. These studies are currently carried out, among others using molecular biology techniques that enable detailed analysis of nucleic acids and proteins, but not only. The breakthrough achievements of 1961 initiated the development both in the field of molecular biology and the science of space, thanks to which today, 60 years after those events, we can combine knowledge and technological achievements from both fields to analyze and understand changes at the molecular level that occur as a result of being in organisms in outer space.</p>","PeriodicalId":20335,"journal":{"name":"Postepy biochemii","volume":"68 2","pages":"169-178"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40566049","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}

It is caused by mutations in the DMD gene encoding dystrophin, which protects muscle fibers upon contraction. Its absence leads to muscle weakening and premature death mostly due to cardio-respiratory failure. Many experimental therapies have been developed to restore functional dystrophin or counteract processes contributing to disease progression. Nonetheless, DMD remains an incurable disease, and glucocorticoids, exerting many side effects, still serve as the “gold standard” of treatment. Hence, there is a need to develop innovative therapeutic options that will at least alleviate the symptoms of DMD. Among them, targeting specific microRNAs (miRs), e.g. miR-378a, restoring normal angiogenesis and the use of cytoprotective factors such as heme oxygenase-1 (HO-1) or hydrogen sulfide (H2S) might be of special interest.

Despite numerous studies, the etiology of this disease remains unclear. Previous studies suggest the involvement of interrelated biochemical pathways, i.e. oxidative and nitrative stress as well as abnormalities of the tryptophan catabolites pathway (TRYCATs) in the depression development. Therefore, the aim of this study was to explain the role of oxidative and nitrative stress as well as disorders in the course of the TRYCATs pathway in the molecular basis of depression. In this study, an attempt was made to determine the effect of single nucleotide polymorphisms, located in genes, encoding enzymes involved in oxidative and nitrative stress, and the TRYCATs pathway on the incidence of depression. Moreover, using an in vivo model of depression, the impact of chronic mild stress stimuli on mRNA expression and protein amount as well as the degree of methylation of the promoter regions of genes encoding enzymes involved in the studied pathways was assessed. The obtained results clearly confirmed the studied biochemical pathways are involved in the development of depression at the molecular level.","PeriodicalId":20335,"journal":{"name":"Postepy biochemii","volume":"116 1","pages":"80-95"},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85174569","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}

The correct epigenetic pattern of eu- and heterochromatin marks allows for maintaining chromatin in an active or transcriptionally silenced state. In the life cycle of angiosperms, epigenetic mechanisms participate in genome reprogramming during: 1) differentiation of sporophyte cells into spore mother cells (SMC) that undergo meiosis, 2) development of female and male gametophytes, within which the gametes differentiate and 3) after double fertilization during the embryo and endosperm development. SMC speciation and control of meiosis, followed by reprogramming of the sperm cells and egg cell genome, are non-cell-autonomous and require RdDM pathway. These processes involve companion cells, which produce „mobile” siRNAs signal molecules. Epigenetic control of gene expression through siRNAs also participates in maintenance of gametes and embryo genome integrity and in the parental imprinting.","PeriodicalId":20335,"journal":{"name":"Postepy biochemii","volume":"22 1","pages":"57-79"},"PeriodicalIF":0.0,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84735720","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}
