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 ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Decoupling enzyme catalysis from thermal denaturation

, 2010
The equilibrium model (EM) (Daniel et al., 2001) postulates two forms of a folded enzyme, one catalytically active (Eact) and the other inactive (Einact), which interconvert via a fast thermal equilibrium (Keq) (Figure A). This model for enzyme catalysis

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Temperature-Responsive Nano-SiO₂ Composite for Improving Shale Stability in Oil-Based Drilling Fluids

The development of nanomicrometer pores and microfractures in shale gas formation leads to frequent wellbore instability during shale gas drilling, which seriously restricts the safe and rapid drilling of shale gas.
