Summary: Abivertinib (AC) is a novel epidermal growth factor receptor tyrosine kinase inhibitor that exhibits highly efficient antitumor activity. This study demonstrates that AC can induce both reactive oxygen species (ROS)-dependent apoptosis and ferroptosis in tumor cells. The Bim- and Bax-mediated mitochondrial pathways play a dominant role in AC-induced ferroptosis and apoptosis.

Summary: The study demonstrates that the relative amount of BAK found in preformed complexes with MCL1 or BCLXL varies across ovarian cancer cell lines and PDXs, with cells bearing BAK/MCL1 complexes showing increased sensitivity to paclitaxel and MCL1 antagonist. This suggests that the assessment of BAK/MCL1 complexes may be useful for predicting response to paclitaxel alone or in combination with BH3 mimetics.

Summary: BID functions as an effector of the intrinsic apoptosis pathway, playing a role both upstream and parallel to BAX, BAK, and BOK, and it may exert its function by releasing cytochrome c.

Summary: At least seven cell death programs are activated during myocardial infarction (MI), but the importance of each program in causing heart damage is not fully understood. In this study, the researchers focused on the role of BAK, a pro-cell death protein, in cardiomyocyte apoptosis and necrosis during MI/reperfusion (MI/R) and non-reperfused MI. They found that the absence of BAK significantly reduced infarct size and necrosis in vivo and in isolated cardiomyocytes. However, the complete deletion of BAK did not affect acute infarct size or long-term scar size, post-infarct remodeling, cardiac dysfunction, or mortality in non-reperfused MI. These results suggest that BAK may be a potential therapeutic target for MI/R.

Summary: Cells lacking both BAX and BAK proliferate less and activate a senescent program when driven into tetraploidy, showing alterations in calcium fluxes that can be rescued by reintroduction of Serca2a or an ER-targeted variant of BAK. This suggests that BAX/BAK prevent tetraploidy-induced senescence by regulating calcium fluxes.

Summary: Small molecule direct BAK activators have the potential to be developed as anti-cancer drugs or tools for studying BAK activation. The thrombopoietin receptor agonist eltrombopag (Eltro) inhibits BAX activation and apoptosis, but in this study, it was found that Eltro directly binds to BAK and induces its activation. Moreover, Eltro also induces BAK-dependent cell death. This finding provides a starting point for the development of more potent and selective direct BAK activators.

Summary: The study revealed that Curcusone C has significant anti-proliferative and apoptotic effects on human endometrial cancer cells, by inducing apoptosis through cytochrome c release and caspase activation, as well as activating mitogen-activated protein kinases. This suggests the potential of Curcusone C as a therapeutic option for endometrial cancer.

Summary: Ironomycin is a drug that disrupts mitochondrial metabolism and induces cell death in cancer cells by reducing mitochondrial iron load and activating BAX/BAK. It exhibits synergy with BH3 mimetics and overcomes venetoclax resistance in cancers such as acute myeloid leukemia.

Summary: In this study, the effect of nano-encapsulated lactoferrin (NE-Lf) on the expression of Bax and Bak genes in stomach cancer cell line AGS was evaluated. The results showed that NE-Lf had a stronger growth inhibition effect compared to lactoferrin, and chitosan had no effect on cell growth. The expression of Bax and Bak genes increased significantly in response to NE-Lf treatment, indicating that lactoferrin can induce apoptosis by interacting with Bax and Bak proteins.

Summary: BAX and BAK are important regulators of apoptosis and play a role in the formation of apoptotic pores. BAK has faster kinetics in forming smaller structures and can accelerate the assembly of BAX. BAX and BAK regulate each other during the formation of apoptotic pores, which affects the release kinetics of mitochondrial components and the activation kinetics of the cGAS/STING pathway.

Summary: Cancer is a major global health concern and cancer determent is a significant public health challenge. Mitochondrial dysfunction is highlighted as a hallmark of cancer cells and mitochondrial membrane permeabilization is considered a major feature in apoptosis-mediated cancer cell death. The mitochondrial permeability transition pore (mPTP) plays a critical role in regulating apoptosis-mediated cancer cell death and is linked with the enzyme hexokinase II for cellular defense and cytochrome c release reduction. The opening/activation of mPTP is influenced by factors such as mitochondrial calcium overload, oxidative stress, and mitochondrial depolarization. This review focuses on the structure and regulation of mPTP-mediated apoptosis mechanisms and discusses the development of novel mPTP-targeting drugs/molecules in cancer treatment.

Summary: Apoptosis is a crucial process for development and tissue homeostasis, and its dysregulation is linked to diseases, including cancer. This study used computational protein design, yeast surface display screening, and structure-based energy scoring to identify 10 diverse peptides that can activate BAK, an apoptotic effector. These peptides, including ones from human proteins BNIP5 and PXT1, were found to induce cell death by disrupting the mitochondrial outer membrane. The findings provide insights into the peptide sequence space that can modulate BAK function and have implications for therapeutic development.
