Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

SSO Suppression Strategy of DFIG-Based Wind Turbine Based on Impedance Reshaping

IOP Conference Series: Earth and Environmental Science, 2020
Abstract In order to suppress the sub-synchronous oscillation (SSO) of DFIG-based wind power generation system, a new suppression strategy based on impedance reshaping is proposed in this paper. Firstly, the impedance model of DFIG-based wind power generation system set in static coordinate system is established, and the mechanism of SSO

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

Aging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Damping Method of High Frequency Resonance for Stator Current Controlled DFIG System under Parallel Compensation Grid [PDF]

, 2020
High-frequency resonances (HFR) is a subsistent issue in a doubly fed induction generator (DFIG) system when it connects to a parallel compensation grid, due to the insufficient phase margin between the impedance of DFIG and grid.
