2‐Pyrazoline‐5‐One Derivative Suppresses Cell Proliferation and Induces Apoptosis With Upregulation of Bax in Breast Cancer Cells

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
2‐Pyrazoline‐5‐one derivative inhibits proliferation and migration and induces Bax‐mediated apoptosis in breast cancer cells. ABSTRACT The most common cancer in women worldwide is still breast cancer. Among its subtypes, luminal A and triple‐negative breast cancers present significant therapeutic challenges due to intrinsic drug resistance and absence ...

Curcumin Attenuates Aroclor 1254‐Induced Oxidative, Genotoxic, and Apoptotic Alterations in HepG2 Cells

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
In HepG2 cells, Aroclor 1254 induced oxidative stress, DNA damage, apoptosis, and mutagenicity; co‐treatment with curcumin restored antioxidant defenses (GSH/thiols; SOD, CAT, GPx, GR, TrxR), reduced ROS and comet/8‐OHdG readouts, and attenuated caspase activation, demonstrating curcumin's hepatoprotective and genoprotective modulation of PCB toxicity.

Mass spectrometry proteomics for studying mitostasis

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Maintaining mitochondrial integrity and function is fundamental to cellular homeostasis. Cells rely on coordinated protein quality control (QC) systems—including intricate chaperone‐protease networks, the ubiquitin‐proteasome system, and cytosolic surveillance pathways—that together form a dynamic, cell‐wide mitostasis network governing the ...
