BCL2 Associated X, Apoptosis Regulator (BAX)
BCL2 associated X, apoptosis regulator (BAX) is a pro-apoptotic member of the BCL2 protein family and a central regulator of the intrinsic, mitochondria-mediated apoptosis pathway.
BCL2 associated X, apoptosis regulator (BAX) is a pro-apoptotic member of the BCL2 protein family and a central regulator of the intrinsic, mitochondria-mediated apoptosis pathway. Under cellular stress, BAX promotes mitochondrial outer membrane permeabilization, facilitating release of apoptogenic factors and activation of downstream caspases such as caspase-3. In normal physiology, this activity helps eliminate damaged or unwanted cells; in disease, altered BAX signaling can contribute to cancer cell survival, tissue injury, neurodegeneration, and fibrotic remodeling.
BAX is functionally opposed by anti-apoptotic proteins such as BCL2 apoptosis regulator (Bcl-2), and many recent studies assess the balance between BAX and Bcl-2 as a readout of apoptotic sensitivity. Because of this role, BAX is frequently investigated as a biomarker and mechanistic target in studies of oxidative stress, cuproptosis-associated mitochondrial stress, autophagy-apoptosis crosstalk, and tissue protection in models of ischemic injury, fibrosis, and chemotherapy resistance.

Where the papers sit
8 papers study bcl2 associated x, apoptosis regulator (bax) directly. Those 8 are one subject: Apoptosis in Disease and Therapy. Apoptotic signaling is being modulated in both directions: induced to kill cancer cells and restrained to protect neural, muscle, and reproductive tissues. Mitochondrial dysfunction, oxidative stress, and calcium handling recur as therapeutic targets. No way of splitting those 8 scores better than chance.
Recent Findings on BCL2 Associated X, Apoptosis Regulator (BAX) — latest 30 papers
Recent studies have examined BCL2 Associated X, Apoptosis Regulator (BAX) in the context of apoptosis-related tissue injury and therapeutic modulation. In adolescent rats exposed to chronic unpredictable mild stress, Ashwagandha and sertraline were compared for their effects on testicular damage and reproductive dysfunction, with BAX, BCL-2, Ki67, and SIRT6 assessed immunohistochemically. Chronic stress was associated with reduced testicular testosterone and cGMP, increased oxidative stress and inflammatory markers, and histopathological injury in the testes; the study evaluated whether treatment could counter these changes through apoptotic pathways 42315798Jun.
BAX was also implicated in an antitumor study of novel phenylahistin derivatives designed to act through dual inhibition of microtubule dynamics and the TP53/BCL-2/BAX signaling axis. Among 33 synthesized compounds, one lead derivative, compound 45, showed strong antiproliferative activity against H460 lung cancer cells, disrupted the microtubule network, induced G2/M arrest, increased p53 expression, inhibited antiapoptotic BCL-2 function, and promoted mitochondrial dysfunction, ROS accumulation, and tumor cell apoptosis. In a mouse allograft model, this compound also outperformed docetaxel in suppressing tumor growth while maintaining a favorable safety profile 42273719Jun.
Although BAX was not explicitly named in the ischemic stroke study, the publication is relevant to apoptosis regulation in injury models. Poliumoside improved outcomes in both OGD/R-injured Neuro-2a cells and a photothrombotic stroke mouse model by reducing ROS, improving mitochondrial function, decreasing apoptosis, and activating the Keap1/Nrf2 antioxidant pathway with upregulation of HO-1 and NQO1. The authors also reported modulation of autophagy-related signaling, suggesting broader cytoprotective effects in neuronal injury 42134761May.
