BioEssays, EarlyView.Multiple enzymes play a crucial role in regulating the biosynthesis of de novo sphingolipids. This regulation starts with the rate‐limiting enzyme, serine palmitoyltransferase (SPT), which catalyzes the first step of the pathway. Disruptions in this regulatory process can lead to serious diseases.

Microsomal superoxide anion production and NADPH-oxidation in a series of 22 aziridinylbenzoquinones [PDF]
, 1989 Several 2,5-bis(1-aziridinyl)-1,4-benzoquinones (BABQs) can be activated to alkylating species by reduction of the quinone moiety. On the other hand, cytotoxicity of these compounds can be induced by redox cycling.

Cancer Communications, EarlyView.Abstract Background Pancreatic cancer's aberrant lipid metabolism fuels cell growth, invasion, and metastasis, yet its impact on immune surveillance and immunotherapy is unclear. This study investigated how sterol regulatory element‐binding transcription factor 1 (SREBP1)‐driven lipid metabolism affects the tumor microenvironment (TME) in pancreatic ...

Chemistry &Biodiversity, EarlyView.ABSTRACT Epimedium (EP) is a traditional Chinese medicine that has been used to treat osteoporosis for several years, but its mechanism of action is unclear. We used ultrahigh‐performance liquid chromatography coupled with triple–quadrupole mass spectrometry (UPLC–QQQ–MS/MS) to detect the components of raw and processed EP samples.

Do Flame Retardants Promote Vitamin D Deficiency? [PDF]
, 2014 Vitamin D deficiency in the Unites States has become more prevalent in recent years. Research has shown that environmental chemicals such as flame-retardants induce hepatic enzymes in the cytochrome P450 family such as CYP24 and CYP3A that are important ...

UPLC-MS/MS analysis of ochratoxin A metabolites produced by Caco-2 and HepG2 cells in a co-culture system [PDF]
, 2017 Ochatoxin A (OTA) is one of the most important mycotoxins based on its toxicity. The oral route is the main gateway of entry of OTA into the human body, and specialized epithelial cells constitute the first barrier.

Chemistry &Biodiversity, EarlyView.ABSTRACT Benzodiazepines are widely used in the treatment of anxiety, but their use may be interrupted due to side effects. This study evaluated the indole alkaloids isocarapanaubine (indole alkaloid 1 [AIN1]) and 18‐β‐hydroxy‐3‐epi‐α‐yohimbine (indole alkaloid 2 [AIN2]), extracted from Rauvolfia ligustrina, in adult zebrafish.
