Epoxide-Opening Cascades in the Synthesis of Polycyclic Polyether Natural Products [PDF]

open access: yes, 2009
The structural features of polycyclic polyether natural products can, in some cases, be traced to their biosynthetic origin. However in case that are less well understood, only biosynthetic pathways that feature dramatic, yet speculative, epoxide-opening

Investigating Mitochondrial Viscosity in Ferroptosis‐Mediated Drug‐Induced Liver Injury using a Double‐Targeted Strategy

open access: yesAdvanced Science, EarlyView.
Utilizing a mitochondrial double‐targeted strategy, a novel near‐infrared fluorescent probe (FTZ‐2) is established for monitoring viscosity variations in ferroptosis‐mediated drug‐induced liver injury. In summary, this work provided a practical strategy for the early diagnosis and evaluation of liver injury.

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

open access: yesAdvanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Dual Targeting of Tau Kinases and Autophagy by Abemaciclib Independent of CDK4/6 Inhibition

open access: yesAdvanced Science, EarlyView.
Abemaciclib rescues cognitive function and attenuates tau pathology in Alzheimer's disease models, but not through its known cancer‐fighting mechanism. This study demonstrates that abemaciclib operates independently of CDK4/6 inhibition, instead directly targeting tau kinases CaMKII and GSK3β while simultaneously promoting autophagic clearance of ...

ERM Inhibition Confers Ferroptosis Resistance through ROS‐Induced NRF2 Signaling

open access: yesAdvanced Science, EarlyView.
ERM inhibition disrupts ERM‐actin interactions, elevating ROS and triggering KEAP1 degradation, which stabilizes and activates NRF2. Nuclear NRF2 induces cytoprotective genes, notably HMOX1, enhancing redox buffering and suppressing lipid peroxidation to resist erastin‐induced ferroptosis.

Carcass quality of feedlot finished steers fed yeast, monensin, and the association of both additives Qualidade de carcaça de novilhos terminados com dietas contendo levedura, monensina e associação de ambos aditivos

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
To evaluate the effects of the supplementation of feed additives on carcass quality in beef cattle, 72 Nellore steers (339.5kg, 20-month old) were feedlot finished and fed for 91 days one of the following diets: 1) control with no additives; or added of ...
