Pro-survival transcriptional programs

Pro-survival transcriptional programs refer to the coordinated activation of gene expression patterns that enable cells to resist apoptotic stimuli and maintain viability under physiological or pathological stress (Hanahan & Weinberg, 2011, Cell). These programs are typically driven by master transcription factors such as Nuclear Factor-kappa B (NF-κB), Signal Transducer and Activator of Transcription 3 (STAT3), and members of the AP-1 family, which upregulate the expression of anti-apoptotic proteins like BCL-2, BCL-XL, and Inhibitors of Apoptosis Proteins (IAPs) (Zhang et al., 2017, Signal Transduct Target Ther; Yu et al., 2014, Nat Rev Cancer). In many diseases, particularly cancer, these programs are constitutively active, allowing malignant cells to evade programmed cell death and develop multi-drug resistance (Holohan et al., 2013, Nat Rev Cancer). Therapeutic strategies often focus on inhibiting the upstream signaling kinases (e.g., IKK, JAK) or the transcription factors themselves to restore apoptotic sensitivity (Taniguchi & Karin, 2018, Nat Rev Mol Cell Biol). While not a single molecular target, these programs represent a critical regulatory node in cellular homeostasis and a major focus for overcoming therapeutic resistance.
