Oxidative stress can disrupt the body’s ability to fight harmful free radicals, leading to premature aging and various health complications. This study investigated the antioxidant and anti-aging properties of four medicinal and edible mushrooms: Ganoderma lucidum, Hericium erinaceus, Pleurotus ostreatus, and Agaricus bisporus. The antioxidant activity of mushroom extracts was evaluated using (DPPH-ABTS-Reducing power). The anti-aging effects were assessed using Human Skin Fibroblasts (HSF) cells subjected to D-galactose-induced aging (30 g/L/72 h) and treated with mushroom extracts (0.03–0.25 mg/mL/72 h). The results demonstrated that all mushrooms have significant antioxidant and anti-aging properties, with low concentrations of extracts (0.03 mg/mL) effectively promoting cell proliferation at an 87% rate in the Agaricus bisporus extract, enhancing cell cycle progression by reducing the arrested cells in the G0/G1 phase to 75%, and promoting DNA synthesis in S phase by more than 16.36% in the Hericium erinaceus extract. Additionally, the extracts reduced DNA damage and Reactive Oxygen Species (ROS) levels, protecting cells from oxidative stress and potentially contributing to anti-aging effects. The mushrooms also exhibited immunomodulatory and anti-inflammatory effects by upregulating the IL-2, IL-4, and downregulating IL-6 expression, indicating their potential to promote general health. These findings suggest the potential of mushroom extracts as natural agents for reducing the negative effects of aging while promoting cellular health. Further research is required to explore the specific bioactive compounds responsible for these beneficial effects and to evaluate their efficacy in vivo.

Mushrooms, renowned for their nutritional value and bioactive compounds, offer potential health benefits, including antioxidants and anti-aging properties. Aging, characterized by cellular and tissue decline, is often associated with autophagy dysfunction, a crucial cellular cleaning process. This study aimed to investigate the neuroprotective, hepatoprotective, and antimicrobial properties of extracts from four medicinal and edible mushrooms: Ganoderma lucidum, Hericium erinaceus, Pleurotus ostreatus, and Agaricus bisporus. The protein, total phenol, and flavonoid content of mushroom extracts were determined. Aging was induced with 120 mg/kg D-galactose and treated with 500 mg/kg mushroom extracts. The study evaluated liver enzyme levels, histopathological changes in liver and brain tissues, gene expression correlated to neurodegeneration (SEPT5-SV2B-ATXN2-PARK2), telomere length, and immunomodulatory and pro-inflammatory (IL-2-IL-4-IL-6) gene expression pathways. Additionally, the antimicrobial potential of mushroom extracts was assessed against several bacteria (Lysinibacillus odyssey, Lysinibacillus fusiformis, Klebsiella oxytoca, and Escherichia coli) using agar well diffusion and lowest minimum inhibitory concentration (MIC) methods. By exploring these diverse aspects, this study aimed to provide a foundation for a better understanding of the potential of mushrooms as natural neuroprotective, hepatoprotective, and antimicrobial agents and their potential applications in human health. Results indicated that all mushroom extracts effectively mitigated oxidative stress. Agaricus bisporus exhibited the highest protein and flavonoid content, and Pleurotus ostreatus displayed the highest phenolic content. Notably, Hericium erinaceus and Ganoderma lucidum extracts demonstrated significant neuroprotective and hepatoprotective properties against D-galactose-induced aging, as evidenced by histopathological examination. All extracts exhibited a significant decrease (p < 0.001) in liver function (serum levels of aspartate aminotransferase (GOT) and alanine aminotransferase (GPT)) and showed immunomodulatory and anti-inflammatory effects, characterized by upregulated IL-2 and IL-4 gene expression and downregulated IL-6 gene expression. Hericium erinaceus demonstrated the most pronounced upregulation (p < 0.001) of SEPT5, SV2B, and telomere length gene expression, suggesting potential anti-aging effects. Furthermore, all mushroom extracts displayed antimicrobial activity against the tested bacterial strains, except Hericium erinaceus, which exhibited antibacterial activity solely against E. coli. Agaricus bisporus exhibited the largest inhibition zones (22 ± 0.06 mm) against Lysinibacillus odyssey, while Hericium erinaceus displayed the largest inhibition zone against E. coli. The MIC value was observed with Agaricus bisporus extract against Lysinibacillus odyssey (1.95 ± 0.16 mg/mL). Lysinibacillus fusiformis exhibited the highest resistance to the tested mushroom extracts. These findings suggest that these edible and medicinal mushrooms possess a wide range of health-promoting properties, including neuroprotective, hepatoprotective, and antimicrobial activities. Further research is needed to fully understand the underlying mechanisms and optimize applications. However, our results provide a strong foundation for exploring these mushrooms as potential natural agents that promote overall health and combat age-related decline.

Agrocybe cylindracea is an important mushroom highly valued as a functional food for its nutritional and medicinal benefits. Many bioactive extracts from A. cylindracea have been found to exhibit antitumor and antioxidant activities. This research investigated the distinct substrates that affected the physicochemical and biocomponent properties and biological efficiency of A. cylindracea. The substrates used were 48% giant juncao grass mixed with 30% Dicranopteris dichotoma grasses, 48% wasted tea leaves mixed with 30% sawdust, and 78% cottonseed hulls, all supplemented with 20% wheat bran and 2% lime. The findings indicated that A. cylindracea grown in the cotton seed hulls had a significant biological efficiency, at 35.8%, followed by the GD + DD (31.5%) and WTL + SD (28.7%). The ash content peaked in the fruiting bodies grown on giant juncao grass and D. dichotoma, while the fat content was highest in those grown on giant juncao grass and D. dichotoma, followed by wasted tea leaves and sawdust. The protein content was significantly higher in the fruiting bodies cultivated on wasted tea leaves and sawdust, followed by cottonseed hulls. The carbon dioxide emissions varied across substrates, with the highest emissions observed during the maturity stage of the fruiting bodies grown on giant juncao grass with D. dichotoma and wasted tea leaves and sawdust. Emissions decreased sharply 110 days after cultivation. Essential metabolites, such as dopamine and caffeine, were enriched in the fruiting bodies grown on wasted tea leaves, sawdust, and cottonseed hulls. In contrast, tyramine and uracil were enriched in those grown on cottonseed hulls.
