Obesity is associated with several endocrine disorders, including hypersensitivity of the hypothalamic-pituitary-adrenal axis. The aim of this study was to investigate the effects of a high carbohydrate diet on structural and ultrastructural features of steroidogenic tissue, as well to evaluate adrenocorticotropic hormone (ACTH), cortisol, and insulin levels in the blood and steroidogenic acute regulatory protein (StAR) expression in the adrenals of gerbils. In electron microscopy, the most pronounced effect of the hypercaloric diet was observed in the zona fasciculata. Plasma levels of ACTH, cortisol, and insulin also showed significant increases. However, no significant change was noted in StAR protein levels. There is evidence that high carbohydrate intake brings about remarkable morphological and functional modifications. This could ultimately lead to mitochondrial alteration and accumulation of lipid droplets, which may lead to inflammation and degeneration of adrenal cells.

Mangrove ecosystems are globally recognized for their blue carbon (C) sequestration capacity. Lignocellulosic detritus constitutes the primary C input to mangrove sediments, but the microbial processes involved in its bioprocessing remain unclear. Using lignocellulosic analysis and metagenomic sequencing across five 100-cm sediment cores, we found a high proportion of lignin (95.

Pancreatic ductal adenocarcinoma (PDAC) displays a high degree of spatial subtype heterogeneity and co-existence, linked to a diverse microenvironment and worse clinical outcome. However, the underlying mechanisms remain unclear. Here, by combining preclinical models, multi-center clinical, transcriptomic, proteomic, and patient bioimaging data, we identify an interplay between neoplastic intrinsic AP1 transcription factor dichotomy and extrinsic macrophages driving subtype co-existence and an immunosuppressive microenvironment.

Immune checkpoint inhibitors (ICIs) have significant therapeutic effects but can also cause fatal lung injury. However, the lack of mouse animal models of ICI-related lung injury (ICI-LI) has limited the in-depth exploration of its pathogenesis. In clinical practice, underlying lung diseases increase the risk of lung injury.
