Suna G, Keskin O, Küçükçetin İÖ, Ayaz A. Dietary antioxidants and flavonoids intake, and their association with inflammation and oxidative stress parameters in asthmatic women: a case-control study. J Clin Biochem Nutr 2024; 74:22-29. [PMID: 38292125 PMCID: PMC10822751 DOI: 10.3164/jcbn.23-60] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 09/10/2023] [Indexed: 02/01/2024] Open
Abstract
Asthma is more prevalent and severe in women, especially after puberty. Studies suggest a potential link between dietary antioxidants, inflammation, and oxidative stress. This study aimed to compare the dietary intake of antioxidants in asthmatic and healthy women, evaluating their potential associations with inflammation and oxidative stress. This study analyzed 30 asthmatic and 30 healthy women's lung function, anthropometry, biochemical parameters, and dietary antioxidant intake using a 161-itemized semi-quantitative food frequency questionnaire. Additionally, the study explored connections between serum inflammatory markers and oxidative stress indicators in relation to dietary intake of antioxidant nutrients and flavonoids. Asthmatic women exhibited higher serum IL-6 levels and lower total antioxidant status compared to healthy controls. Nevertheless, no significant differences were observed in dietary antioxidant micronutrient intake. Healthy controls demonstrated a notably higher intake of anthocyanidins compared to asthmatic women. Furthermore, the study identified a negative correlation between flavonol intake and serum total oxidant status, as well as between flavan-3-ols intake and serum oxidative stress index. Dietary differences in flavonoid and flavonoid-rich foods intake among asthmatic women may affect their serum IL-6 levels and oxidative stress. Promoting a diverse diet rich in flavonoids could benefit women with asthma by mitigating inflammation and oxidative stress.

Inhibition of lincRNA-Cox2 alleviates apoptosis and inflammatory injury of lipopolysaccharide-stimulated human bronchial epithelial cells via the Nrf2/HO-1 axis. J Clin Biochem Nutr 2023; 72:234-241. [PMID: 37251964 PMCID: PMC10209602 DOI: 10.3164/jcbn.22-102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 11/28/2022] [Indexed: 05/31/2023] Open
Abstract
This study mainly explored the role and mechanism of lincRNA-Cox2 in inflammatory injury of human bronchial epithelial cells. BEAS-2B cells were stimulated with lipopolysaccharide to establish an in vitro inflammatory injury model. Real-time polymerase chain reaction was used to detect lincRNA-Cox2 expression in LPS-stimulated BEAS-2B. Cell viability and apoptosis of cells were assessed using CCK-8 and Annexin V-PI double staining. The contents of inflammatory factors were determined by enzyme-linked immunosorbent assay kits. The protein levels of nuclear factor erythrocyte 2-related factor 2 and haem oxygenase 1 protein levels were measured by Western blot. The results showed that lincRNA-Cox2 was upregulated in LPS-stimulated BEAS-2B cells. lincRNA-Cox2 knockdown inhibited apoptosis and the release of tumour necrosis factor alpha, interleukin 1beta (IL-1β), IL-4, IL-5, and IL-13 in BEAS-2B cells. lincRNA-Cox2 overexpression had the opposite effect. lincRNA-Cox2 knockdown also inhibited LPS-induced oxidative damage in BEAS-2B cells. Further mechanistic studies showed that inhibition of lincRNA-Cox2 upregulated the levels of Nrf2 and HO-1, and si-Nrf2 reversed the effects of si-lincRNA-Cox2. In conclusion, lincRNA-Cox2 knockdown inhibited BEAS-2B apoptosis and the level of inflammatory factors by activating the Nrf2/HO-1 pathway.

Abstract
Sirtuins (SIRTs) are nicotine adenine dinucleotide(+)-dependent histone deacetylases regulating critical signaling pathways in prokaryotes and eukaryotes, and are involved in numerous biological processes. Currently, seven mammalian homologs of yeast Sir2 named SIRT1 to SIRT7 have been identified. Increasing evidence has suggested the vital roles of seven members of the SIRT family in health and disease conditions. Notably, this protein family plays a variety of important roles in cellular biology such as inflammation, metabolism, oxidative stress, and apoptosis, etc., thus, it is considered a potential therapeutic target for different kinds of pathologies including cancer, cardiovascular disease, respiratory disease, and other conditions. Moreover, identification of SIRT modulators and exploring the functions of these different modulators have prompted increased efforts to discover new small molecules, which can modify SIRT activity. Furthermore, several randomized controlled trials have indicated that different interventions might affect the expression of SIRT protein in human samples, and supplementation of SIRT modulators might have diverse impact on physiological function in different participants. In this review, we introduce the history and structure of the SIRT protein family, discuss the molecular mechanisms and biological functions of seven members of the SIRT protein family, elaborate on the regulatory roles of SIRTs in human disease, summarize SIRT inhibitors and activators, and review related clinical studies.

Abstract
Sirtuins are nicotinamide adenine dinucleotide (NAD+)-dependent lysine deacylases and deacetylases that participate in a variety of cellular processes, including transcriptional activity, energy metabolism, DNA damage response, inflammation, apoptosis, autophagy, and oxidative stress. As a result, sirtuins are linked to multiple pathophysiological processes, such as cardiovascular diseases, metabolic diseases, autoimmune diseases, infectious diseases, and respiratory diseases. Asthma is the most common respiratory disease, which is characterized by airway inflammation and airway remodeling. Accumulating evidence has indicated that sirtuins are involved in the pathogenesis of asthma. Furthermore, some studies have suggested that sirtuin modulators are potential agents for the treatment of asthma via alteration of the expression or activity of sirtuins. In this review, we illustrate the role of sirtuins in asthma, discuss related molecular mechanisms, and evaluate the sirtuins-targeted therapy for asthma.

Abstract
Ancylostoma ceylanicum is a zoonotic soil-derived nematode that parasitizes human and animal intestines, causing malnutrition and iron-deficiency anemia. Calreticulin is a multifunctional protein involved in all stages of parasitic infection. Studies have found that parasites can secret calreticulin to regulate the host's immune response. To explore the immunogenicity of the eukaryotic expression plasmid of Ancylostoma ceylanicum calreticulin (Ace-CRT), we constructed a recombinant Ace-CRT eukaryotic expression plasmid (pEGFP-N3-Ace-CRT). Successful expression of the target protein in Human Embryonic Kidney (HEK) 293 T cells was confirmed by indirect immunofluorescence and Western blot analysis. BALB/c mice were immunized with pEGFP-N3-Ace-CRT plasmid. Measuring IgG antibody levels in immunized mice sera by ELISA showed that the recombinant plasmid stimulated IgG antibody production in mice. Spleen lymphocytes were collected from vaccinated mice to determine the proportion of T cell subsets and the expression levels of cytokines. Flow cytometry revealed that the percentage of CD3 + CD4+ and CD3 + CD8+ T cells in mice spleen in the immunization group was significantly higher than that in the control group. Recombinant plasmid immunization increased IL-4, IL-10, IL-12, and IL-13 expression while decreasing IL-5, IL-6, and INF-γ in mice spleens. These results indicate that the eukaryotic plasmid constructed in this study had good immunogenicity and mainly induced a T helper 2 response in the host, laying a foundation for screening candidate molecules for anti-hookworm vaccines.
