The cell mediated immune response is considered to play a crucial role in HPV clearance. The viral load and number of lesions increase when there is an imbalance between the T-helper 1 and T-helper 2 immune responses. Interleukin (IL)-19 is a cytokine that belongs to interleukin 10 cytokines family and constitutes a sub-family with IL-20, IL-22 and IL-24. IL-19 is mainly produced by activated monocytes and to a lesser extent by B-cells, keratinocytes and fetal membranes. IL-19 was found to shift T-cell maturation away from the pro-inflammatory T-helper 1 cells toward the anti-inflammatory T-helper 2 cells. It induces IL-4 and IL-13 production in T cells and apoptosis in monocytes. Aim: This study aimed to measure serum level of IL-19 in patients with warts compared to healthy controls and to find out the correlation between this level and number, size and clinical types of warts. Methods: The study included 50 patients with warts and 50 control subjects. Serum concentration of IL-19 was measured by enzyme-linked immune sorbent assay. Results: Interleukin-19 serum level was significantly lower in patients with warts than in controls (P < 0.003). Moreover, there was a significant positive correlation between IL-19 serum level and the number of warts (P = 0.027). Conclusion: Serum level of IL-19 was significantly lower in patients with warts, and this low level might be crucial for an effective cell mediated immunological response to HPV.","PeriodicalId":44217,"journal":{"name":"AIMS Molecular Science","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70226818","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}

As one of the cell degradation systems, it participates in the lysosomal pathway process of degrading damaged proteins and subcellular organelles to maintain cell metabolism and energy states. Moreover, autophagy is essential for regulating organelle quality control and cell homeostasis. In recent decades, a large number of studies have demonstrated that autophagy abnormalities are present in a variety of human malignancies and that autophagy plays a crucial role in all stages of tumor development. Multiple tumors interfere with autophagy's normal regulation and use autophagy's essential properties to restructure their proteome, reprogram their metabolism, and adapt to stress. This article primarily discusses how autophagy either promotes or inhibits cancer development, the significance of autophagy in maintaining cell genome stability, and the role of selective autophagy in the reshaping and quality control of tumor cells.","PeriodicalId":44217,"journal":{"name":"AIMS Molecular Science","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70226866","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}

Its higher prevalence in women makes it necessary to study pathways/systems that could participate and/or be involved in its development, as well as those that could be affected by hormonal factors, which, in this case, are estradiol levels. In this sense, one of the systems under study that is gaining special relevance in the scientific community is the brain renin-angiotensin system and its regulatory proteolytic enzymes. This system is strongly modulated by estrogens, and it is also connected with the cerebral glucose metabolism through the angiotensin IV receptor, also recognized as the insulin-regulated aminopeptidase (IRAP). Due to the fact that the cerebral glucose metabolism is highly compromised in patients with Alzheimer's disease, it is necessary to know the elements of the systems and their functions in this process, namely, the cerebral renin-angiotensin system, estradiol and IRAP, an enzyme and receptor co-localized in brain tissue with the insulin-dependent glucose transporter 4 (GLUT4). Knowledge of the connection between them could shed light on the molecular mechanisms of this disease and also provide new diagnostic and therapeutic targets.","PeriodicalId":44217,"journal":{"name":"AIMS Molecular Science","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70226665","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}

In recent years, great progress has been achieved in the study of transition metal-catalyzed construction of various C-X bonds involving aromatic amines and benzyl amines-derived quaternary ammonium salts by cleavage of C-N bonds. This review describes the transition metal-catalyzed reaction of quaternary ammonium salts to construct C-X bonds by cleavage of C-N bond. Moreover, if chiral benzylamines-derived quaternary ammonium salts are used, a variety of highly enantiomeric pure chiral organic compounds can also be obtained.

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme for various biological enzymatic reactions such as those involved in the TCA cycle. To investigate the molecular mechanisms involved in carcinogenesis, the transcription system of genes associated with mitochondrial function should be elucidated. In this study, we isolated several mitochondrial function-associated bidirectional promoters and tested whether they responded to NAD+-metabolism regulating compounds, namely, trans-resveratrol (Rsv), 2-deoxy-D-glucose (2DG), 3-amino benzamide (3AB), and olaparib (OLA), in HeLa S3 cells. Transient transfection and luciferase (Luc) reporter assay showed that the IDH1 promoter was prominently activated by these compounds. The IDH1 gene, which encodes a nicotinamide adenine dinucleotide phosphate (NADP+) dependent isocitrate dehydrogenase, is frequently mutated in glioma and leukemia cells. In this study, RT-PCR showed that IDH1 gene and protein expression was induced in response to the NAD+-regulating drugs Rsv and 3AB. However, IDH1 protein amount was rather stable at control level. The result suggested that a post-transcriptional controlling system works to keep IDH1 at a stable level.","PeriodicalId":44217,"journal":{"name":"AIMS Molecular Science","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70227592","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}
