Objective: The aim of the present study is to isolate and characterize the bioactive compounds from Pleurotus djamor against human breast cancer (MDA-MD-231) and mouse T cell lymphoma (EL4) cell lines.
Materials And Methods: Sequential fractionization and column chromatography methods were involved in compound isolation. The structures of the isolated compound were determined by NMR, GC/MS, and X-ray crystallography studies.
Results: The isolated compounds 1- 4 [D-mannitol (C1), ergosta-5,7,22-trien-3β-ol (C2), 5,8- epidioxy-ergosta-6-22-dien-3β-ol (C3), and palmitic acid (C4)] are white crystal and amorphous powder in nature. All these compounds were isolated from this mushroom for the first time. In vitro lipid peroxidation activities of isolated compounds were determined by ferric thiocyanate (FTC) and thiobarbituric acid (TBA) method. The sterol derivatives C2 and C3 compounds displayed strong antioxidant activity and were not significantly different (p<0.05) to α-tocopherol. This finding elaborates on the isolation of a cytotoxic compound C2 and C3 from P. djamor via a rapid elution method.
Conclusion: The compound C3 has exhibited better cytotoxic activity against MDA-MD-231 and EL4 cells. The present finding and data might provide new insights into the possible therapeutic and pharmaceutical use for the design of anti-cancer drugs from this edible mushroom.

Vitamin D is critically important for sustainable human health, and the rising prevalence of deficiency-related diseases has increased interest in natural sources. This study explores the potential of epiphytic lichen-forming fungi, known for their unique metabolites, as a novel biosource of vitamin D for pharmaceutical and nutraceutical applications. Fourteen epiphytic lichen species were collected using a stratified sampling method from four mountainous forests in the Marmara Region of Türkiye.

Colorectal cancer (CRC) is characterised by microbial dysbiosis. Trimethylamine (TMA) and trimethylamine-N-oxide (TMAO) are gut microbiota-derived metabolites produced from dietary precursors that are implicated in CRC progression. However, the underlying mechanisms by which TMA or TMAO affect CRC progression remain largely unexplored.

TDP-43 is a nuclear protein encoded by the TARDBP gene, which forms pathological aggregates in various neurodegenerative diseases, collectively known as TDP-43 proteinopathies, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). These diseases are characterized by multiple pathological mechanisms, with disruptions in lipid regulatory pathways emerging as a critical factor. However, the role of TDP-43 in the regulation of the brain lipid homeostasis and the potential connection of TDP-43 dysfunction to myelin alterations in TDP-43 proteionopathies remain poorly understood, despite the fact that lipids, particularly cholesterol, comprise nearly 70% of myelin.

Background: Previous Mendelian randomization (MR) studies investigating the causal relationship between lipid traits and chronic obstructive pulmonary disease (COPD) have primarily focused on individuals of European (EUR) ancestry, limiting the generalizability of findings. This study aimed to address this limitation.
Methods: Summary-level data for individuals of East Asian (EAS), African (AFR), and Hispanic (HIS) ancestry were obtained from large-scale genetic databases.

Gastric cancer (GC) remains one of the leading causes of cancer-related mortality worldwide, with limited responses to immune checkpoint blockade (ICB) therapies in most patients. Increasing evidence indicates that the tumor immune microenvironment (TIME) plays a crucial role in immunotherapy outcomes. Among various metabolic abnormalities in the TIME, dysregulated lipid metabolism has emerged as a critical determinant of immune cell fate, differentiation, and function.
