The relationship between tissue inhibitor of metalloproteinases-1 and KCNJ5 mutation in aldosterone-producing adenoma patients.

KCNJ5 somatic mutations in aldosterone-producing adenoma (APA) are linked to higher left ventricular mass index (LVMI) and worse diastolic function. We previously identified an association between plasma tissue inhibitor of metalloproteinases-1 (TIMP-1) and an aldosterone-induced increase in LVMI and diastolic dysfunction. This study aimed to investigate the association between the presence of KCNJ5 somatic mutation and plasma TIMP-1 in APA patients.

Citrisorbicillinol, an undescribed hybrid sorbicillinoid with osteogenic activity from Penicillium citrinum ZY-2.

Citrisorbicillinol (1), along with six other known compounds (2-7), was isolated from an endphyte Penicillium citrinum ZY-2 of Plantago asiatica L. Citrisorbicillinol (1) was characterized as a skeletally unprecedented hybrid sorbicillinoid, and its unique framework is likely formed by intermolecular [4 + 2] cycloaddition between intermediates derived from citrinin and sorbicillinoid biosynthetic gene clusters. Compounds 1 and 2 demonstrated to promote osteoblastic differentiation in MC3T3-E1 cells, and to be osteogenic in the prednisolone induced osteoporotic zebrafish.

Neuroprotective α-pyrones from Nigrospora oryzae, an endophytic fungus residing in Taxus chinensis var. mairei.

Endophytes coevolve with plant hosts and thus are more probable to acquire the character (in favor) of producing undescribed bioactive metabolites. Consequently, the topic has been intensely investigated for over two decades, but endophytic metabolites with neuroprotective effect remain scarce. The study presents the discovery of eight undescribed (named solanapyrones U-Z and prosolanapyrones A and B) and six known pyrones (solanapyrones A-C and E-G) from the culture of Nigrospora oryzae, an endophytic fungus associated with Taxus chinensis var.

Aldosterone suppresses cardiac mitochondria.

Elevated serum aldosterone promotes arterial hypertension, cardiac hypertrophy, and diastolic dysfunction. However, the effect of elevated aldosterone levels on cardiac mitochondria remains unclear. We used primary cultures of mouse cardiomyocytes to determine whether aldosterone has direct effects on cardiomyocyte mitochondria, and aldosterone-infused mice as a preclinical model to evaluate the impact of aldosterone in vivo.

Macrophages play an important role in aldosterone-induced myocardial fibrosis, in which the first key steps are macrophage recruitment and infiltration. We hypothesized that IL-6 may be a key mediator of aldosterone-induced macrophage recruitment and infiltration. To test this hypothesis, we designed cell studies with a human monocytic cell line THP-1 that with monocyte/macrophage functions to explore the signaling pathway of aldosterone-induced macrophage infiltration, and further investigated the phenomenon and consequent pathway in aldosterone-infused mice studies.

Interaction between gut microbiota and ethnomedicine constituents.

Covering: 2000 to 2018 (October) Trillions of microbes, collectively termed as gut microbiota, reside in the gastrointestinal tract and are involved in the physiology of their hosts. In humans, disease incidence and medical therapy are found to be associated with gut microbiota composition. Since ethnomedicines are largely plant-derived and orally ingested, this review summarizes the interactions of gut microbiota with ethnomedicine constituents (overwhelmingly, natural phytochemicals) to highlight the knowledge accumulation in (1) the modulation of the gut microbiota profile by ingested natural compounds, and (2) the gut microbial conversion of natural products into the 'daughter molecules' with potent bioactivities.
