High mobility group protein B2 (HMGB2) (HMGB2)

High mobility group protein B2 (HMGB2) is a non-histone chromosomal protein that plays a critical role in maintaining chromatin structure and regulating gene expression (UniProt P27003). It belongs to the HMG-box family and is involved in various cellular processes, including DNA repair, transcription, and the regulation of the senescence-associated secretory phenotype (SASP) (Aird et al., 2016, PMID: 27322068). HMGB2 is frequently overexpressed in multiple cancer types, where it promotes cell proliferation, migration, and invasion, making it a significant target for therapeutic intervention (PMID: 30105441). Targeting HMGB2 at the mRNA level using technologies like siRNA or antisense oligonucleotides (ASOs) aims to silence its expression and inhibit tumor progression or modulate inflammatory responses. While primarily an intracellular protein, its role in disease states and its accessibility via nucleic acid-based therapies highlight its potential as a therapeutic target.

Targeting HMGB2 mRNA via RNA interference (RNAi) or antisense oligonucleotides (ASOs) leads to the degradation of the transcript or inhibition of translation, thereby reducing the levels of the HMGB2 protein and its downstream effects on gene expression and chromatin structure.
