Five new degraded diterpenoids trigoxyphins J-N (1-5), among them trigoxyphins K and L have a novel carbon skeleton, together with four known analogues (6-9) have been obtained from the ethanol extract of the twigs of Trigonostemon xyphophylloides. Compounds 1-5 were evaluated for their cytotoxic activity in vitro against three human tumor cell lines by MTT assay. The results exhibited that Trigoxyphin N (5) showed moderate cytotoxicities against SPC-A-1 and SGC-7901 cancer cell lines.

Tanshinones, the major bioactive diterpenes in Salvia miltiorrhiza Bunge, are widely used to treat cardiovascular and cerebrovascular diseases. While jasmonates (JAs) are known to modulate tanshinones accumulation, the molecular link between JA signalling and tanshinone biosynthesis remains unclear. Here, we identify SmWRKY33, a JA-responsive WRKY transcription factor, as a key regulator of tanshinone biosynthesis through multiomic and genetic analyses.

Coronary artery atherosclerosis (CAA) stands as a prominent etiological contributor to global cardiovascular morbidity and mortality. Its pathogenesis entails intricate interplays among genetic predisposition, environmental factors, and lifestyle determinants. Trace elements, though necessitated in minuscule quantities, have emerged as potential modulators of CAA progression, yet their exact impact remains unclear.

The short lifespan of polymorphonuclear neutrophils (PMNs) in vitro poses challenges, as their limited viability restricts functional assays and experimental manipulations. The HL-60 cell line serves as a valuable model for neutrophil-like differentiation, yet the functional relevance of ATRA- and DMSO-induced differentiation remains incompletely understood. In the present study, we aimed to characterize the differentiation potential of all-trans retinoic acid (ATRA) and dimethyl sulfoxide (DMSO) on HL-60 cells and compare their functionality with primary PMNs.

Non-small cell lung cancer (NSCLC) is one of the leading causes of cancer-related deaths, remaining a significant challenge in terms of early detection, effective treatment, and improving patient survival rates. In this study, we investigated the anticancer mechanism of rubiarbonol B (Ru-B) and its derivative 3-O-acetylrubiarbonol B (ARu-B), a pentacyclic terpenoid in gefitinib (GEF)-sensitive and -resistant NSCLC HCC827 cells. Concentration- and time-dependent cytotoxicity was observed for both Ru-B and ARu-B.

Background: Retinol-binding protein 4 (RBP4) is a vitamin A transport protein synthesized in the liver and also plays a crucial role in inflammation and immune regulation. Low serum vitamin A levels have been observed in both pediatric and adult patients with ulcerative colitis (UC). The association between serum vitamin A levels and serum RBP4 levels, as well as the underlying mechanism involved inimpaired vitamin A transport during inflammation in UC patients, has yet to been investigated.
